Has anyone run across this problem when trying to define a custom tag handler in
version 1.2b3? I'm trying to test the insertion and use of a simple custom tag handler
using the template TagDef tag.
The custom tag handler extends XDocletTagSupport and I have the following line in my
target template file (my own version of entitycmp.xdt):
<XDtTagDef:tagDef namespace="FdasEjb"
handler="myxdoclet.resources.fdas.xdoclet.handler.FdasEjbTagsHandler"/>
I'm using the EjbDocletTask and I have the following subtask defined:
<entitycmp
templateFile="${fdas.xdoclet.template.dir}/entitycmp.xdt"/>
My ant ejbdoclet task is defined with the following line:
<taskdef
name="ejbdoclet"
classname="xdoclet.modules.ejb.EjbDocletTask"
classpathref="fdas.test.class.path"
/>
where "fdas.test.class.path" contains classpath definitions for all XDoclet jars, the
XJavadoc jar, any external library jars that XDoclet depends on, as well as the path
to all my application classes including the custom tag handler class.
However, whenever I try to run this task, I get the following error:
[ejbdoclet] (XDocletMain.start 47 ) Running <entitycmp/>
[ejbdoclet] Generating CMP class for 'ejb.EmployeeBean'.

BUILD FAILED
I've tried running this with ant versions 1.5.2, 1.5.3-1 and even 1.4.1. I've even
modified xdoclet.tagshandler.TagDefTagsHandler to print out the classpath (i.e.
AntClassLoader.getClasspath()) that the AntClassLoader will consult to load in
classes. All XDoclet jars, the XJavadoc jar, and the path to my custom tag handler
class are present in the classpath definition.
Anyone have any ideas? At the very least, perhaps someone can point me to a sample
custom tag handler/template/ant build file that's known to work? This would at least
allow me to verify that it's not some quirky runtime environment issue.
Best Regards,
Richard
