How to make ClassLoader find CharsetProvider

[sverker]

In JDK 1.4 there is support for adding a charset by creating a class that extends java.nio.charset.spi.CharsetProvider and one that extends java.nio.charset.Charset.

The CharsetProvider is identified by placing a file called java.nio.charset.spi.CharsetProvider in META-INF/services of a jar-file in the classpath and should then be loaded.

This works fine when I run standalone but when I put the jar file in server/default/lib, it does not work. The classloader can't find my provider and it is never instansiated. I've checked which charsets are availible according to the classloader at that time and my charset is not included eventhough I have no problem to instanciate classes from that jar.

So I suspect that my jar file is loaded by some custom classloader which doesn't support the charsetprovider. Where should I look?

I see now that none of the charsets in $JAVA_HOME/jre/lib/charsets.jar is availible neither

I managed to get it to work by adding my jar-file to JBOSSCLASSPATH in run.sh but that's ugly.

I believe that the bug is somewhere in the classes that loads the jar-files from /lib, that it doens't scan the META-INF/services directory. If someone could give me a hint of where to look I'd solve it.

4 years later, this problem still exists. I had to proceed with the same very ugly hack.

Will I spend time to file a bug request? Well, given that the JBoss team had 4 years to read this forum post that points to an obvious bug, I think I'll pass. Maybe I'll file it next year, it's not like anyone's in a hurry...
