cgen task
Hi everyone,
i'm trying to play a bit with CAyenne cgen task, to see if i can
automate the geration of pojo counterparts to my data objects, to use as
dto in a JAX-WS service.
i've created mi pojo.vm template file and placed it in same directory
with the ant script
project
+---- generate_pojo.xml
|
+---- pojo.vm
|
+---- src
generate_pojo.xml looks like :
<?xml version="1.0" encoding="UTF-8"?>
<project name="changeme" default="all" basedir=".">
<target name="generate pojos" >
<path id="classpath">
<!-- my local cayenne directory -->
<fileset dir="D:/java/cayenne-3.0RC2-win/lib" >
<include name="cayenne-tools-3.0RC2.jar" />
<include name="cayenne-server-3.0RC2.jar" />
<include name="third-party/ashwood-2.0.jar" />
<include name="third-party/commons-collections-3.1.jar" />
<include name="third-party/commons-logging-1.1.jar" />
<include name="third-party/velocity-1.3.jar" />
<include name="third-party/vpp-2.2.1.jar" />
</fileset>
</path>
<echo message="classpath setup " />
<typedef resource="org/apache/cayenne/tools/antlib.xml">
<classpath refid="classpath"/>
</typedef>
<echo message="task inited" />
<delete dir="src/com/sapidata/piemme/pojo" />
<mkdir dir="src/com/sapidata/piemme/pojo" />
<cgen map="src/PMMap.map.xml"
destDir="src/com/sapidata/piemme/pojo"
makepairs="false"
usepkgpath="false"
includeEntities="*"
template="pojo.vm"
outputPattern="*.java"/>
</target>
</project>
but executing results in
D:\java\click-click\clickclick\pm-test\GeneraPojo.xml:39:
org.apache.velocity.exception.ResourceNotFoundException: Unable to find
resource 'pojo.vm'
at
org.apache.velocity.runtime.resource.ResourceManagerImpl.loadResource(ResourceManagerImpl.java:501)

org.apache.cayenne.tools.CayenneGeneratorTask.execute(CayenneGeneratorTask.java:163)
removing the attributes template="pojo.vm" generates the classes, but
using default templates.
Where should be put pojo.vm ?

That looks right to me when I compare it to my Cayenne 1.2 templates.
As a test, try specifying an absolute path of
\java\click-click\clickclick\pm-test\pojo.vm and see what it does.
Maybe for 3.0 it is now looking in the classpath instead of relative
to the ant task base.
Another good general-purpose way to track these kinds of things down
is to install ProcessMonitor and see where Windows is actually trying
to read the file from.

You might also be able to run ant in debug mode and get more
information that way.
