Creating an ant task from xml fragment

[Ashley Williams <ag...@mac.com>]

Hi,

I have a fragment of ant xml and would like to create a task or  
target from it in my java code. For example here is the xml text:


                 <ejbdoclet ejbspec="2.1">
                   <fileset includes="**/*Bean.java"/>
                   <deploymentdescriptor/>
                   <remoteinterface/>
                   <homeinterface/>
                   <localinterface/>
                   <localhomeinterface/>
                   <jboss version="4.0"/>        <!----- this is a  
subtask, could prove tricky -->
                 </ejbdoclet>

And from the xdoclet website the ejb doclet class is:  
xdoclet.modules.ejb.EjbDocletTask, which I believe will help form a  
taskdef.
So from these two pieces of information, can I create the  
corresponding task/target that I can run in my code?

Also can I run a task on its own or does it have to be in a target?


Any pseudo code inside the following method would be very helpful -  
although the less pseudo the better ;)


Target createTarget(Node xml, Class taskdefClass) {
}


Thanks

look at the embedding ant bit of the docs. you dont create XML; you 
create the tasks as java classes


EjbDoclet doclet=new EjbDoclet();
doclet.setProject(myproject);   //something like this?
doclet.setEjbSpec("2.1")
//maybe this
JBoss jboss=doclet.createJBoss();

//then run it.
doclet.execute();
