Strange JBoss error

When I start JBoss (even a clean install of JBoss), I get the following error (and the JAR file is in the right place):
"java.lang.NoClassDefFoundError: javax/activation/DataSource" (see stack below)

07:38:37,399 INFO [Engine] ContextConfig[/jboss-net]: Added certificates -> request attribute Valve

The activation.jar is in the lib folder, and like I said even if I create/run a clean JBoss package I still get this error. I am running Fedora c2.

Any ideas?

Thank you,

I'm seeing something similar, trying to get a SOAP example to work. It appears to be due to the method signature for javax/activation/datasource not being able to handle byte arrays.

I've got Apache SOAP 2.3.1 and the latest JAF 1.0.2 from Sun - the code where I'm seeing the error is in the soap.jar
public void setRootPart(byte[] b, String contentType)
throws MessagingException {
ByteArrayDataSource ds = new ByteArrayDataSource(b, contentType);
DataHandler dh = new DataHandler(ds);

The signature for DataHandler and a data source requires a javax.activation.datasource obj, which ByteArrayDataSource isn't?

I dunno, its maddening.

Well, just a brief, in probably unhelpful follow up - w/o changing anything, except (in Eclipse) the version of the Javs SDK used (from 1.4.2 to 1.5), I got my app to compile and run.

My guess is its a bug. There's a mention of a change to the DataHandler to fix a bug in it in the last update, so ....

I agree. Here's the link:
