problem finding classes at runtime [message #262412]

Hi all

I have the problem that, at runtime, a plugin that should access a remote
session bean brings up the following errors.
Root exception is java.lang.ClassNotFoundException:
org.jnp.interfaces.NamingContextFactory

I have included the necessary jar (jnp-client.jar from the jboss client dir)
but the problem still persists at runtime.

Any ideas?

Cheers,
Michael

The project's build properties do not affect the classpath during runtime.
The classpath of a plugin includes its own JARs (s specified in the plugin
manifest), classes provided by any required plugins and the boot classpath
(+endorsed libraries). The regular classpath specified when launching the
VM is not visible from plugins.

Hi Rafale

Do you have a concrete idea that I could use? The mentioned
'XBootclasspath' does not work..

Thanks,
Michael

Did you check FAQ 73 in Chapter 3 of http://eclipsefaq.org?

Maybe "How do I get code that calls getContextClassLoader() to load my
plugin class?" from PDE FAQ (http://eclipse-wiki.info/PDEFaq) helps.

i checked a few FAQs in there. i tried to update the classpath by using
'PDE-Tools-Update Classpath' but that only threw out the JARs that I added
(?) and did not really help...

I'll browse a bit more through the faq...

Cheers,
Michael

This problem seems to be very persistent. I tried several things from the
FAQ, the WIKI and some other sources - with no success whatsoever.

I even tried to add the classpath to the missing jar at runtime
-classpath %classpath%;D:\...\jnp-client.jar

but that didn't change a thing. I excepted at least the above to work out -
but it didn't.

Ideas?

Cheers,
Michael

The command-line should look like this:

eclipse [any arguments you use to pass to Eclipse] -vmargs
-Xbootclasspath/a:<path to the JAR including the JAR>

Is that what you are doing (including the -vmargs)?
