You can then simply run the Project and have the needed libraries in your deployment location.

But remember to define the properties for addressing the target library. In this example :

    <properties>
        <glassfish.home>/opt/programs/glassfish</glassfish.home>
        <deployment.dir>${glassfish.home}/glassfish/domains/my-domain/lib</deployment.dir>
    </properties>

my maven assembly plugin

I want the provided dependencies in the current project and all the included submodules to take place in the current project's target/lib-lib directory.

how to reset mysql password

If you know the root password, but want to change it, see Section 12.4.1.6, “SET PASSWORD Syntax”.
If you set a root password previously, but have forgotten it, you can set a new password. The following sections provide instructions for Windows and Unix systems, as well as generic instructions that apply to any system.

B.5.4.1.1. Resetting the Root Password: Windows Systems

On Windows, use the following procedure to reset the password for all MySQL root accounts:

1. Log on to your system as Administrator.
2. Stop the MySQL server if it is running. For a server that is running as a Windows service, go to the Services manager: From the Start menu, select Control Panel, then Administrative Tools, then Services. Find the MySQL service in the list and stop it.
   If your server is not running as a service, you may need to use the Task Manager to force it to stop.
   
3. Create a text file containing the following statements. Replace the password with the password that you want to use.
   
   

   UPDATE mysql.user SET Password=PASSWORD('MyNewPass') WHERE User='root';
   FLUSH PRIVILEGES;

   Write the UPDATE and FLUSH statements each on a single line. The UPDATE statement resets the password for all root accounts, and the FLUSH statement tells the server to reload the grant tables into memory so that it notices the password change.
   
4. Save the file. For this example, the file will be named C:\mysql-init.txt.
5. Open a console window to get to the command prompt: From the Start menu, select Run, then enter cmd as the command to be run.
6. Start the MySQL server with the special --init-file option (notice that the backslash in the option value is doubled):
   
   

   C:\> C:\mysql\bin\mysqld --init-file=C:\\mysql-init.txt

   If you installed MySQL to a location other than C:\mysql, adjust the command accordingly.
   The server executes the contents of the file named by the --init-file option at startup, changing each root account password.
   You can also add the --console option to the command if you want server output to appear in the console window rather than in a log file.
   If you installed MySQL using the MySQL Installation Wizard, you may need to specify a --defaults-file option:
   
   

   C:\> "C:\Program Files\MySQL\MySQL Server 5.1\bin\mysqld.exe"
            --defaults-file="C:\\Program Files\\MySQL\\MySQL Server 5.1\\my.ini"
            --init-file=C:\\mysql-init.txt

   The appropriate --defaults-file setting can be found using the Services Manager: From the Start menu, select Control Panel, then Administrative Tools, then Services. Find the MySQL service in the list, right-click it, and choose the Properties option. The Path to executable field contains the --defaults-file setting.
   
7. After the server has started successfully, delete C:\mysql-init.txt.

You should now be able to connect to the MySQL server as root using the new password. Stop the MySQL server, then restart it in normal mode again. If you run the server as a service, start it from the Windows Services window. If you start the server manually, use whatever command you normally use.

How to parse a PDF

PDFBox is a Java API from Ben Litchfield that will let you access the contents of a PDF document. It comes with integration classes for Lucene to translate a PDF into a Lucene document.
 

JPedal is a Java API for extracting text and images from PDF documents.
 

PDFTextStream is a Java API for extracting text, metadata, and form data from PDF documents. It also comes with an integration module making it easier to convert a PDF document into a Lucene document.
 

XPDF is an open source tool that is licensed under the GPL. It's not a Java tool, but there is a utility called pdftotext that can translate PDF files into text files on most platforms from the command line.
 

Based on xpdf, there is a utility called pdftohtml that can translate PDF files into HTML files. This is also not a Java application.

Important matter in indexing --> Solr

Data sent to Solr is not immediately searchable, nor do deletions take immediate
effect. Like a database, changes must be committed frst. Unlike a database, there
are no distinct sessions (that is transactions) between each client, and instead there
is in-effect one global modifcation state. This means that if more than one Solr client
were to submit modifcations and commit them at similar times, it is possible for part
of one client's set of changes to be committed before that client told Solr to commit.
Usually, you will have just one process responsible for updating Solr. But if not, then
keep this in mind.

Solr 1.4 Enterprise Search Server (Packt, 2009, 1847195881) 

index-time-boosting while posting an xml to solr

Here is a sample XML fle you can HTTP POST to Solr:

<add allowDups="false">
<doc boost="2.0">
<field name="id">5432a</field>
<field name="type" ...</field>
<field name="a_name" boost="0.5"></field>
<!-- the date/time syntax MUST look just like this (ISO-8601)-->
<field name="begin_date">2007-12-31T09:40:00Z</field>
</doc>
<doc>
<doc>
<field name="id">5432a</field>
<field name="type" ...
<field name="begin_date">2007-12-31T09:40:00Z</field>
</doc>
<!-- more here as needed -->
</add>


The allowDups defaults to false to guarantee the uniqueness of values in the feld
that you have designated as the unique feld in the schema (assuming you have such
a feld). If you were to add another document that has the same value for the unique
feld, then this document would override the previous document, whether it is
pending a commit or it's already committed. You will not get an error.
If you are sure that you will be adding a document that is not
a duplicate, then you can set allowDups to true to get a
performance improvement.

Boosting affects the scores of matching documents in order to affect ranking in 
score-sorted search results. Providing a boost value, whether at the document or
feld level, is optional. The default value is 1.0, which is effectively a non-boost.
Technically, documents are not boosted, only felds are. The effective boost value 
of a feld is that specifed for the document multiplied by that specifed for the feld.

Specifying boosts here is called index-time boosting, which is rarely
done as compared to the more fexible query-time boosting. Index-time
boosting is less fexible because such boosting decisions must be decided
at index-time and will apply to all of the queries.

The OSGi Architecture

The OSGi technology is a set of specifications that define a dynamic component system for Java. These specifications enable a development model where applications are (dynamically) composed of many different (reusable) components. The OSGi specifications enable components to hide their implementations from other components while communicating through services, which are objects that are specifically shared between components. This surprisingly simple model has far reaching effects for almost any aspect of the software development process.

Though components have been on the horizon for a long time, so far they failed to make good on their promises. OSGi is the first technology that actually succeeded with a component system that is solving many real problems in software development. Adopters of OSGi technology see significantly reduced complexity in almost all aspects of development. Code is easier to write and test, reuse is increased, build systems become significantly simpler, deployment is more manageable, bugs are detected early, and the runtime provides an enormous insight into what is running. Most important, it works as is testified by the wide adoption and use in popular applications like Eclipse and Spring.

How to deploy Solr on Tomcat

• Step 1 : Go to http://lucene.apache.org/solr/ to get the last version of apache Solr . 

• Step 2 : Make a folder somewhere in your computer and name it 'solr_home' (it can have any name). I assume that you have made a folder with the path : C:\ solr-home.
• Step 3 : Copy the following folders to you solr-home directory which you made in the last step. 

1. apache-solr-x.x.x/example/lib
2. apache-solr-x.x.x/example/solr/conf
3. apache-solr-x.x.x/example/solr/bin

• Step 4 : Copy the war file placed in the ./apache-solr-x.x.x/dist folder which has a name like apache-solr-x.x.x.war (where x.x.x is the version of your solr core) and paste it in your tomcat webapps directory. 
• Step 5 : Rename the file 'solr-x.x.x.war'  to solr.zip.
• Step 6 : Now you have to set the Solr home page in order to tell tomcat where to save your indexes.  The first way to approach this aim is to open the web.xml file in Notepad located in the Solr.zip/WEB-INF directory. Find the <env-entry> element (it should be commented by default). Copy it whole and paste it to the bottom of your xml doc. something like :

<env-entry>
<env-entry-name>solr/home</env-entry-name>
<env-entry-value>C:\ solr-home</env-entry-value>
<env-entry-type>java.lang.String</env-entry-type>
</env-entry> .

Also you can set the solr home directory in tomcat configuration panel. To do that , right-click on the icon of tomcat in the notification area , select configure,  go to the  java tab, add the following line to the java options :

-Dsolr.solrhome=C:\solr-home

• Step 7 : Run the tomcat and go to the url http://localhost:8080/solr  . Thats it !

Java Message Service API (the JMS API)

General idea of messaging

Messaging is a form of loosely coupled distributed communication, where in this context the term 'communication' can be understood as an exchange of messages between software components. Message-oriented technologies attempt to relax tightly coupled communication (such as TCP network sockets, CORBA or RMI) by the introduction of an intermediary component, which in this case would be a queue. The latter approach allows software components to communicate 'indirectly' with each other. Benefits of this include message senders not needing to have precise knowledge of their receivers, since communication is performed using this queue. This is the first of two types: point to point and publish and subscribe.

Java Message Service API Overview

The Java Message Service (JMS) defines the standard for reliable Enterprise Messaging. Enterprise messaging, often also referred to as Messaging Oriented Middleware (MOM), is universally recognized as an essential tool for building enterprise applications. By combining Java technology with enterprise messaging, the JMS API provides a powerful tool for solving enterprise computing problems.

Enterprise messaging provides a reliable, flexible service for the asynchronous exchange of critical business data and events throughout an enterprise. The JMS API adds to this a common API and provider framework that enables the development of portable, message based applications in the Java programming language.

The JMS API improves programmer productivity by defining a common set of messaging concepts and programming strategies that will be supported by all JMS technology-compliant messaging systems.

The JMS API is an integral part of the Java 2, Enterprise Edition (J2EE) platform, and application developers can use messaging with components using J2EE APIs ("J2EE components").

Version 1.1 of the JMS API in the J2EE 1.4 platform has the following features:

• Message-driven beans enable the asynchronous consumption of JMS messages.
• Message sends and receives can participate in Java Transaction API (JTA) transactions.
• J2EE Connector Architecture interfaces that allow JMS implementations from different vendors to be externally plugged into a J2EE 1.4 application server.
  

The addition of the JMS API enhances the J2EE platform by simplifying enterprise development, allowing loosely coupled, reliable, asynchronous interactions among J2EE components and legacy systems capable of messaging. As a developer, you can easily add new behavior to a J2EE application with existing business events by adding a new message-driven bean to operate on specific business events.

The J2EE platform's Enterprise JavaBeans (EJB) container architecture, moreover, enhances the JMS API in two ways:

• By allowing for the concurrent consumption of messages
• By providing support for distributed transactions, so that database updates, message processing, and connections to EIS systems using the J2EE Connector Architecture can all participate in the same transaction context.

The Java Management Extensions (JMX) API

The JMX API is a standard API for management and monitoring of resources such as applications, devices, services, and the Java virtual machine.
Typical uses of the JMX technology include:

• Consulting and changing application configuration.
• Accumulating and publishing statistics about application behavior.
• Notifying users or applications of state changes and erroneous conditions.

The JMX API includes remote access, so a remote management program can interact with a running application for the above purposes.

Software versioning

Software versioning is the process of assigning either unique version names or unique version numbers to unique states of computer software. Within a given version number category (major, minor), these numbers are generally assigned in increasing order and correspond to new developments in the software.

Spring Roo

Spring Roo is an open source software tool that uses convention-over-configuration principles to provide rapid application development of Java-based enterprise software^[1]. The resulting applications use common Java technologies such as Spring Framework, Java Persistence API, Java Server Pages, Apache Maven and AspectJ^[2]. Spring Roo is a member of the Spring portfolio of projects.

http://en.wikipedia.org/wiki/Spring_Roo
http://www.springsource.org/roo

Convention over configuration

Convention over Configuration (also known as Coding by convention) is a software design paradigm which seeks to decrease the number of decisions that developers need to make, gaining simplicity, but not necessarily losing flexibility.
The phrase essentially means a developer only needs to specify unconventional aspects of the application. For example, if there's a class Sale in the model, the corresponding table in the database is called sales by default. It is only if one deviates from this convention, such as calling the table "products_sold", that one needs to write code regarding these names.
When the convention implemented by the tool you are using matches your desired behavior, you enjoy the benefits without having to write configuration files. When your desired behavior deviates from the implemented convention, then you configure your desired behavior.

you should run these commands, each on a single separate line

What Is Solr?

Solr is the popular, blazing fast open source enterprise search platform from the Apache Lucene project. Its major features include powerful full-text search, hit highlighting, faceted search, dynamic clustering, database integration, and rich document (e.g., Word, PDF) handling. Solr is highly scalable, providing distributed search and index replication, and it powers the search and navigation features of many of the world's largest internet sites.
Solr is written in Java and runs as a standalone full-text search server within a servlet container such as Tomcat. Solr uses the Lucene Java search library at its core for full-text indexing and search, and has REST-like HTTP/XML and JSON APIs that make it easy to use from virtually any programming language. Solr's powerful external configuration allows it to be tailored to almost any type of application without Java coding, and it has an extensive plugin architecture when more advanced customization is required.
See the complete feature list for more details.
For more information about Solr, please see the Solr wiki.

Comparison Between Solr And Sphinx Search Servers

Similarities

• Both Solr and Sphinx satisfy all of your requirements. They're fast and designed to index and search large bodies of data efficiently.
• Both have a long list of high-traffic sites using them (Solr, Sphinx)
• Both offer commercial support. (Solr, Sphinx)
• Both offer client API bindings for several platforms/languages (Sphinx, Solr)
• Both can be distributed to increase speed and capacity (Sphinx, Solr)

Here are some differences

• Solr, being an Apache project, is obviously is Apache2-licensed. Sphinx is GPLv2. This means that if you ever need to embed or extend (not just "use") Sphinx in a commercial application, you'll have to buy a commercial license.
• Solr is easily embeddable in Java applications.
• Solr is built on top of Lucene, which is a proven technology over 7 years old with a huge user base (this is only a small part). Whenever Lucene gets a new feature or speedup, Solr gets it too. Many of the devs committing to Solr are also Lucene committers.
• Sphinx integrates more tightly with RDBMSs, especially MySQL.
• Solr can be integrated with Hadoop to build distributed applications
• Solr can be integrated with Nutch to quickly build a fully-fledged web search engine with crawler.
• Solr can index proprietary formats like Microsoft Word, PDF, etc. Sphinx can't.
• Solr comes with a spell-checker out of the box.
• Solr comes with facet support out of the box. Faceting in Sphinx takes more work.
• Sphinx doesn't allow partial index updates for field data.
• In Sphinx, all document ids must be unique unsigned non-zero integer numbers. Solr doesn't even require a unique key for many operations, and unique keys can be either integers or strings.
• Solr supports field collapsing to avoid duplicating similar results. Sphinx doesn't seem to provide any feature like this.

What IS AppScale?

AppScale is an open-source implementation of the Google App Engine cloud computing interface. It is being developed by researchers in the UC Santa Barbara RACELab. AppScale enables execution of Google App Engine (GAE) applications on virtualized cluster systems. In particular, AppScale enables users to execute GAE applications using their own clusters with greater scalability and reliability than the GAE SDK provides. Moreover, AppScale executes automatically and transparently over cloud infrastructures such as the Amazon Web Services (AWS) Elastic Compute Cloud (EC2) and Eucalyptus, the open-source implementation of the AWS interfaces.
