JBoss comes with a set of
examples that cover various J2EE and JBoss concepts. I have converted
most of the examples into Eclipse projects, so you can experiment with the code.
You can get more information about the examples in the
JBoss 2.4+ Documentation.
Install Example Projects
- Click Window, click Preferences, expand Java node, click Classpath
Variables and click New...
- Put JBOSS_DIST in Name.
- Click Folder... and navigate to C:/jboss-3.0.1RC1_tomcat-4.0.4, click OK,
click OK and click Yes.
- Open projects.zip shipped with this document.
- Extract entire contents including folder names from projects.zip to
|Eclipse Classpath Variables (Window, Preferences, Java,
Classpath Variables) are used to incorporate folders or jars into your
project. This makes it easy to upgrade libraries by simply changing where the
Classpath Variable points.|
|An exploded ear file is the uncompressed structure
representing the ear file format. JBoss can deal with ears and wars in this
uncompressed format, which makes it ideal for debugging and HotSwap class
replacement. Basically you can unzip an ear file to a directory to see its
structure. All work is done outside the exploded ear folder. Eclipse deploys
the classes for you and the build.xml does the rest. You should never modify
the ear folder directly as you will loose any changes when an Ant target
|The Eclipse Build output folder (Right-click on project,
Properties, Java Build Path) is where the class files are stored after a
compile. For a JBoss project this could be your Servlets, EJBs, clients, etc
that go directly in the exploded ear or war file. This removes the step of
deploying your classes manually.|
|Eclipse Required projects on the build path (Right-click
on project, Properties, Java Build Path, Projects) allows you to link several
projects together. Since you cannot always put client and server code
together in one project itís handy to link them together.|
|Ant scripts are used to automate many tasks such as
building ear folder, building war folder, copying templates and deployment
descriptors, copying JBoss configuration files, creating jars, creating and
deploying compressed ears, etc. In Eclipse just right click on the build.xml
and click Run AntÖ to see the targets you can run.|
