EJB noClassDefFoundError

hi all
i have successfully deployed all the necessary ejbs and compiled
the client .java file into .class file
but when i start to deploy the ejbs on blazix,
run the client .class file to access or call the methods
in ejbs. it appears the error as follow:
exception in thread "main" java.lang.NoClassDefFoundError
at java.lang.classLoader.defineclass1<native methods>
at java.lang.classLoader.defineclass1<unknown source>
.....
thanks in advance

Hi Min,

but when i start to deploy the ejbs on blazix,
run the client .class file to access or call the methods
in ejbs. it appears the error as follow:

Please make clear two things:

Is this a client error, or a server error? I mean you�ve got this error message from the server log files, or from the client�s console?

What is exactly the name of the class missing (not found)? Is this an application specific class (one you�ve created), or is it a blazix specific class?

Regards.

hi ,
because i tested it in a single pc.
the error msg is appearing in the client console and the class file is the
file written by myself.
it is quite fishy
thank u first
i have changed the classpath and path for several times
no result

First I�d like you to check this thread Simple]http://www.coderanch.com/t/315815/EJB-JEE/java/Simple-Session-bean-weblogic]Simple Session bean in Weblogic 8.1[/url], it might provide you useful information. Secondly I would advice you to get familiar with your application server�s class loading architecture (sooner or latter you�ll have to do it anyway), since different containers apply different strategies. For a brief introduction you might like checking this link: Understanding]http://www.theserverside.com/articles/article.tss?l=ClassLoading]Understanding J2EE Application Server Class Loading Architecture[/url].

thank you very much
but the link cannot route the page to me
well the problem is for the blazix that there are too few doc
for its internal mechanism
the procedure of the class loading is what i wanne know.
unluckily,we could only be a general doctor to see the sympotem
of our patient,not knowing the inside world
