Help with new ant task that uses spring
The problem is my ant task cannot seem to locate an xml file that is to
be located in the classpath. I have supplied the directory the xml file
is in to the taskdef (the same classpath definition works on the java
and junit tasks). When I invoke the task, my task is found, but the
spring config file (configured to read via the classpath) is not found.
I would really appreciate some scolding. Thanks.
My taskdef is as follows:
<taskdef name="authsum"
classname="org.authsum.configuration.ant.taskdefs.AuthSumProperty">
<classpath>
<path refid="springframework.classpath"/>
<fileset file="../dbom/build/dbom.jar"/>
<fileset file="../services/build/services.jar"/>
<!-- the configContext.xml file is in
../services/src/conf -->
<dirset dir="../services/src/conf"/>
<!-- the following is to pick the log4j props -->
<dirset dir="../src/conf"/>
<fileset file="../anttask/build/anttask.jar"/>
</classpath>
</taskdef>
BUILD FAILED

If you made it this far, thanks. The project is a web-based java
properties manager in which property values are "tagged" in order to use
in grid like environments. More info at

Even with fork="false"?

Ok then a workaround would be to put the confic.xml file into a jar and
include the jar in your class path to ensure that what you say is
actually true for all resources

I thank you for responding, however, I can able to successfully use
spring from within ant (using the java and junit tasks). My java and
junit tasks (which work) have the exact same classpath as my taskdef.
It seems that by having it in a taskdef does not allow for classpath
resources that are directories. My other resources (spring jars, custom
pojo's) appear to be visible to the ant task. Just not directories in
which resources are kept.

This is really more of a spring config issue than an ant issue from what
I can see from the stack trace. I remember Spring being quite awkward
with respect to loading xml files from classpath, can you build a basic
unit test like so:
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import junit.framework.TestCase;
public class BaseDAOTestCase extends TestCase {
protected final Log log = LogFactory.getLog(getClass());
protected final static ApplicationContext CTX;
static {
String[] paths = {"applicationContext.xml"};
CTX = new ClassPathXmlApplicationContext(paths);
}
public void testClasspath() {
assert(true);
}
}
basically this will remove ant completely from the equation and allow
you to focus on why Spring cannot resolve the config file.
I have had problems in the past trying to run stuff like this from
within eclipse (as it has it's own ideas of classpath), so make sure you
do this from command line and make sure that CLASSPATH variable is not
set first, hope this helps

Found the answer to my question with this post:
http://www.ant-tasks.com/msg/9124.html
I ended up swapping out the AntClassLoader as directed in this post.

Can your task be loaded using the system CLASSPATH as well? If so, it
will be loaded from there and your <classpath> will be ignored (since
your class doesn't know about it).
If you run "ant -debug" you should see which classloader is loading
which class.
