Digester: Problems with ClassLoader
I am working with Digester inside an Application
Server (Oracle iAS), and I had some problems because
the method
DigesterRuleParser.IncludeRule.includeXMLRules, uses
the ClassLoader for the class DigesterRuleParser, not
the ClassLoader in use for the current thread (as this
is a container, is not the same ClassLoader for the
system jars and the application jars).
So, I just replace the line 368 of the file
DigesterRuleParser.java:
URL fileURL =
DigesterRuleParser.this.getClass().getClassLoader().getResource(fileName);
with the line:
URL fileURL =
Thread.currentThread().getContextClassLoader().getResource(fileName);
I think this can be useful, and my tests works fine,
maybe somebody wants to add this code to the
repository

Good catch! I just applied a slight tweak to this patch (if there is no
thread context class loader, fall back to the class loader that loaded
this class) because not all Digester users are running in a container
that supports the thread context class loader. Fixed in nightly build
20031001.
Thanks for the patch.
