Guys,
I have my own task and collection implemented and I use it like that:
<taskdef name="myTask" classname="com...MyTask"
classpathref="std.classpath" loaderref="myTask"/>
<typedef name="download_files" classname="com.....AntFileInfoSet"
classpathref="std.classpath" loaderref="myTask"/>
<typedef name="file" classname="com.....AntFileInfo"
classpathref="std.classpath" loaderref="myTask"/>
...
<myTask .......>
<download_files id="fl.flieInfos">
<file name="xxx" .../>
<file name="xxx" .../>
</download_files>
</myTask>
...
My task and collection jar file is located at std.classpath. The problem
is the AntFileInfoSet class is loaded by different classloader then
AnFileInfoSet class defined by section <download_files/>. In that case I
always get ClassCastException doing casting in AntFileInfoSet:
public List getAntFileInfos() {
if (refid != null) {
return ((AntFileInfoSet)
getProject().getReference(refid)).getAntFileInfos(); !!!!!!
} else {
return antFileInfos;
}
}
In case I copy my jar file to ANT_HOME\lib directory and then run ant,
everything is ok as only one classloader is used.
As you can see I use loaderref="myTask" property but it doesn't help.
Can you help me?
Thx,
Tomek
