Subject Re: [jira] Commented: (OPENJPA-8) java.util.MissingResourceException: system is missing product derivations
Date Mon, 14 Aug 2006 19:25:02 GMT
So... before I got update the jira, I want to go make sure it's not 
something stupid I'm doing.

Classpath defined like this in ant...

    <path id="project.classpath">
        <pathelement location="${basedir}/lib/commons-collections-3.2.jar"/>
        <pathelement location="${basedir}/lib/commons-lang-2.1.jar"/>
        <pathelement location="${basedir}/lib/commons-logging-1.0.4.jar"/>
        <pathelement location="${basedir}/lib/commons-pool-1.3.jar"/>
        <pathelement location="${basedir}/lib/derby-10.1.3.1.jar"/>
        <pathelement 
location="${basedir}/lib/geronimo-j2ee-connector_1.5_spec-1.0.1.jar"/>
        <pathelement 
location="${basedir}/lib/geronimo-jms_1.1_spec-1.0.1.jar"/>
        <pathelement 
location="${basedir}/lib/geronimo-jta_1.0.1B_spec-1.0.1.jar"/>
        <pathelement location="${basedir}/lib/openjpa-jdbc-0.9.0.jar"/>
        <pathelement location="${basedir}/lib/openjpa-jdbc-5-0.9.0.jar"/>
        <pathelement location="${basedir}/lib/openjpa-kernel-0.9.0.jar"/>
        <pathelement location="${basedir}/lib/openjpa-kernel-4-0.9.0.jar"/>
        <pathelement location="${basedir}/lib/openjpa-kernel-5-0.9.0.jar"/>
        <pathelement location="${basedir}/lib/openjpa-lib-0.9.0.jar"/>
        <pathelement 
location="${basedir}/lib/openjpa-persistence-0.9.0.jar"/>
        <pathelement 
location="${basedir}/lib/openjpa-persistence-jdbc-0.9.0.jar"/>
        <pathelement location="${basedir}/lib/openjpa-project-0.9.0.jar"/>
        <pathelement location="${basedir}/lib/openjpa-xmlstore-0.9.0.jar"/>
        <pathelement location="${basedir}/lib/persistence-api-1.0.jar"/>
        <pathelement location="${basedir}/lib/serp-1.11.0.jar"/>
    </path>

(have also tried it like....)

    <path id="project.classpath">
        <fileset dir="${basedir}/lib" includes="*.jar"/>
    </path>


===========

Task defined like...

    <taskdef name="openjpac" 
classname="org.apache.openjpa.ant.PCEnhancerTask">
        <classpath refid="project.classpath" />
    </taskdef>

Target defined like...

    <target name="enhance-src">
        <openjpac>
            <classpath refid="project.classpath"/>
            <fileset dir=".">
                <include 
name="${basedir}/src/main/java/tutorial/persistence/*.java" />
            </fileset>
        </openjpac>
    </target>


and I still get that same MissingResourceException...

When digging into the Services.getImplementors(String serviceName, 
ClassLoader loader) method, I print out all the URL's returned by a call 
to URLClassLoader.getURLs, and it gives me the following:

Obviously, the 
'META-INF/services/org.apache.openjpa.conf.ProductDerivation' file is 
not gonna be in any of those libraries.

What am I missing?
