Hi,
nope, there is no other posting.
I haven't had the time yet to investigate my assumption, especially
because I have no ready to use example.
Let me explain my assumption:
- I had a problem with the new layout (inlined jars) of the runtime
plugin in the Ruta Workbench, to be more precise, with the classpath
generated by the launch delegate
- the new Ruta launcher was strongly inspired by the AE Launcher plugin
concerning how the classpath of the new vm is generated
- I fixed the problem for the Ruta launcher
- the AE launcher code hasn't changed, therefore there might still occur
the same problem
About the problem in
AnalysisEngineLaunchConfigurationDelegate.getClasspath():
If not in development mode, the classpath is expanded by adding the jar
of the bundles (e.g., runtime):
extendedClasspath.add(pluginIdToJarPath("org.apache.uima.runtime"));
I suppose that this does not work for inlined jars (e.g.,
uimaj-core.jar) and causes ClassNotFoundExceptions or similar.
If in development mode, the classpath is expanded by adding the jar entries:
Bundle bundle =
LauncherPlugin.getDefault().getBundle("org.apache.uima.runtime");
if (bundle != null) {
Enumeration<?> jarEnum = bundle.findEntries("/", "*.jar", true);
while (jarEnum != null && jarEnum.hasMoreElements()) {
URL element = (URL) jarEnum.nextElement();
extendedClasspath.add(FileLocator.toFileURL(element).getFile());
}
}
I solved the problem in the Ruta launcher by simply adding the second
code part to the first one. This actually resolves the jars within the
bundle and add them to the classpath.
Overall, the question is whether jars within jars that are listed in the
classpath are correctly resolved by the vm.
Best,
Peter
