Question

Hi,

I get the "java.lang.ClassNotFoundException: org.jnp.interfaces.NamingContextFac tory" error while running my packaged ejb3 swing client jar. Here's the stack trace.

Here are my packaged swing client Jar contents:-

MetaDB-Client.jar
  \net\.. - contains class files(from both client and server)
  META-INF
    MANIFEST.MF
  jndi.properties

Here's my jndi.properties:-

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
java.naming.provider.url=localhost:1099

Here's my MANIFEST.MF:-

Manifest-Version: 1.0
Main-Class: net.massmatrix.metadb.ui.MainFrame
Class-Path: jbossall-client.jar

Manifest contents from my jar:-

Manifest-Version: 1.0
Created-By: 1.6.0_18 (Sun Microsystems Inc.)
Main-Class: net.massmatrix.metadb.ui.MainFrame

Command used to create the jar:-

jar cfm MetaDB-Client.jar MANIFEST.MF net\* jndi.properties

Command used to run the jar:-

java -jar MetaDB-Client.jar

I have the jbossall-client.jar in my classpath

G:\Courses\OSUMC\Installables\June 5\New>echo %CLASSPATH%
.;G:\Courses\OSUMC\WORK\Software - New\jboss-5.0.1.GA\client

What else am i missing ?

Thanks.

Answer 1

All you have to do is add the jbossall-client.jar library to the clients lib folder.
ClassPath in the MANIFEST cannot have * in it.
Here is the tutorial for the JAR manifest classpath.
