Question about using references

[ntreeby]

I have a build.xml, and I am trying to use references so I can re-use my PCTConnection definitions.

However, I am seeing different behavior depending on how I set up my PCT taskdef.

For reference:

• Windows 10
• OpenEdge 11.7.6 (using %DLC%\pct\PCT.jar)
• java -version: openjdk version "11.0.13" 2021-10-19 LTS
  OpenJDK Runtime Environment Microsoft-27990 (build 11.0.13+8-LTS)
  OpenJDK 64-Bit Server VM Microsoft-27990 (build 11.0.13+8-LTS, mixed mode)
• ant -version: Apache Ant(TM) version 1.9.8 compiled on December 25 2016 (using %DLC%\ant)
• DLC env var is set correctly

If I do this:

<project ...>
    <property environment="env"/>
    <taskdef resource="PCT.properties" classpath="${env.DLC}/pct/PCT.jar"/>
    <typedef resource="types.properties" classpath="${env.DLC}/pct/PCT.jar"/>
    
    <PCTConnection id="mydb" dbName="myDb" logicalName="myDb" hostName="somehost" dbPort="12345" readOnly="true"/>

    <target name="compile">
        <PCTCompile ...>
            <PCTConnection refid="mydb"/>
            ...
        </PCTCompile>
    </target>
</project>

Then, I get this error during the PCTCompile when it tries to reference the PCTConnection:

ant compile
...
Class com.phenix.pct.PCTConnection (loaded via AntClassLoader[C:\Progress\OpenEdge11\pct\PCT.jar]) is not a subclass of com.phenix.pct.PCTConnection (loaded via AntClassLoader[C:\Progress\OpenEdge11\pct\PCT.jar])

BUILD FAILED
C:\Git\progress-monitor\build\build.xml:30: mydb doesn't denote a PCTConnection
...

However, if I change to this:

<project ... xmlns:pct="PCT:eu.rssw.pct">
    <property environment="env"/>
    <taskdef uri="PCT:eu.rssw.pct"
             resource="eu/rssw/pct/antlib.xml"
             classpath="${env.DLC}/pct/PCT.jar" />
    
    <pct:dbConnection id="mydb" dbName="myDb" logicalName="myDb" hostName="somehost" dbPort="12345" readOnly="true"/>

    <target name="compile">
        <pct:compile ...>
            <pct:dbConnection refid="mydb"/>
            ...
        </pct:compile>
    </target>
</project>

ant compile
...
BUILD SUCCESSFUL
Total time: 2 seconds

Why is this? The Wiki suggests that the former approach will work, but it clearly isn't working for me. Is there something I'm missing?

Do you specify the classpath in the <taskdef> node ? If so, you should switch to ant -lib /path/to/pct.jar, or drop pct.jar in your $ANT_HOME/lib directory. You shouldn't see this problem anymore.

Yes, I do. I thought I had C&P'd that into my original post, but I think some auto-formatting wiped it out. Here is what I am using with my <taskdef> and <typedef> nodes:

    <taskdef resource="PCT.properties" classpath="${env.DLC}/pct/PCT.jar"/>
    <typedef resource="types.properties" classpath="${env.DLC}/pct/PCT.jar"/>

This works just fine for everything else, except when I use id="abc" / refid="abc" with PCT types.

A few issues were already raised ( https://github.com/Riverside-Software/pct/issues?q=is%3Aissue+sort%3Aupdated-desc+AntClassLoader ), the classpath attribute shouldn't be set in your build file. I've removed the reference to classpath attribute in the installation guide.
