All Implemented Interfaces:

EJBDeploymentTool

public class WebsphereDeploymentTool
extends GenericDeploymentTool

WebSphere deployment tool that augments the ejbjar task. Searches for the WebSphere specific deployment descriptors and adds them to the final ejb jar file. WebSphere has two specific descriptors for session beans:

• ibm-ejb-jar-bnd.xmi
• ibm-ejb-jar-ext.xmi

and another two for container managed entity beans:

• Map.mapxmi
• Schema.dbxmi

In terms of WebSphere, the generation of container code and stubs is called deployment. This step can be performed by the websphere element as part of the jar generation process. If the switch ejbdeploy is on, the ejbdeploy tool from the WebSphere toolset is called for every ejb-jar. Unfortunately, this step only works, if you use the ibm jdk. Otherwise, the rmic (called by ejbdeploy) throws a ClassFormatError. Be sure to switch ejbdeploy off, if run ant with sun jdk.

isRebuildRequired

protected boolean isRebuildRequired(File genericJarFile,
 File websphereJarFile)

Helper method to check to see if a WebSphere EJB 1.1 jar needs to be rebuilt using ejbdeploy. Called from writeJar it sees if the "Bean" classes are the only thing that needs to be updated and either updates the Jar with the Bean classfile or returns true, saying that the whole WebSphere jar needs to be regenerated with ejbdeploy. This allows faster build times for working developers.

The way WebSphere ejbdeploy works is it creates wrappers for the publicly defined methods as they are exposed in the remote interface. If the actual bean changes without changing the the method signatures then only the bean classfile needs to be updated and the rest of the WebSphere jar file can remain the same. If the Interfaces, ie. the method signatures change or if the xml deployment descriptors changed, the whole jar needs to be rebuilt with ejbdeploy. This is not strictly true for the xml files. If the JNDI name changes then the jar doesn't have to be rebuild, but if the resources references change then it does. At this point the WebSphere jar gets rebuilt if the xml files change at all.

Parameters:

genericJarFile - java.io.File The generic jar file.

websphereJarFile - java.io.File The WebSphere jar file to check to see if it needs to be rebuilt.

Returns:

true if a rebuild is required.

getClassLoaderFromJar

protected ClassLoader getClassLoaderFromJar(File classjar)
                                     throws IOException

Helper method invoked by isRebuildRequired to get a ClassLoader for a Jar File passed to it.

Parameters:

classjar - java.io.File representing jar file to get classes from.

Returns:

a classloader for the jar file.

Throws:

IOException - if there is an error.
