RE: unnamed component. Class not found

Hi Xavier,

I cannot see what is going wrong. Are you sure that all the stubs for
all the components are there. Java 1.5 generates the RMI stubs on the
fly and in Java 1.4 you need to use rmic. You  mentioned that the stubs
are there so I should assume that the error is coming from somewhere
else.

Could you send us the complete stack trace (enable stacktrace in
bin/default.ini)?
Also, you could get a cvs head check out and try your class again, just
to try. The version in cvs does not need the file rmitargets anymore and
generates the stubs automatically when needed.

The error that you get points that it cannot find the class that you
want to deploy which is usually caused by a missing/buggy jar file. Be
careful with duplicated jars in your classpath.

Hi,

May I have help on this:

I compile a component using javac1.4 (source 1.4 target 1.4), rmic
stubversion 1.2.
Compilation works well, stubs are generated.

It runs well with jdk1.5 but fails on jdk1.4:
jvm 1.5:
[TRACE][RMI TCP Connection(2)-xxx.xxx.xxx.xx] SFCORE_LOG - sfResolved:
HERE sfClass to ch.cern.openlab.smartfrog.xmlUtil.ForceParamValueImpl
**
org.smartfrog.sfcore.componentdescription.ComponentDescriptionImpl.sfRes
olve(ComponentDescriptionImpl.java:479)
**

org.smartfrog.sfcore.prim.PrimImpl.sfResolveHere(PrimImpl.java:179) **
etc..

jvm 1.4:
[TRACE][RMI TCP Connection(2)-xxx.xxx.xxx.xx] SFCORE_LOG - sfResolved:
HERE sfClass to ch.cern.openlab.smartfrog.xmlUtil.ForceParamValueImpl
**

I suspect it has something to do with xerces. I use
org.apache.xml.serialize.OutputFormat and XMLSerializer in a class
imported by my component but when I use this class outside smartfrog
with both jvms 1.4 and 1.5 it works. It even works fine when used by a
smartfrog component on a jvm 1.5. It generates an xsl file in adding
elements into a sax contentHandler.

I can't find out what's wrong. Have you ever encountered sth similar?

Attached: diagnostic report when it fails (jvm 1.4) and differences
with diagnostic when it works fine (jvm 1.5).


Thanks in advance,
Xavier
