Hi all,
I've exactly the same trouble with :
- NT Workstation 4.0, SP5
- jdk 1.3
- tomcat 3.2.1
- JBoss 2.2 (in a separate JVM)
Everything works fine while executing directly the code (I mean not from
a JSP file). But if I execute it from tomcat, I've the same error.
The file jnp-client.jar is in the correct WEB-INF\lib. It contains the
class file for org.jnp.interfaces.NamingContextFactory. I've tried to
suppress the jboss-client.jar and jbosssx-client.jar from this
directory, to test it : I then get another error, which means to me that
the directory is definitively the good one.
But the jnp-client.jar doesn't seem to be loaded, or another jar file
is needed. I've copied all files from jboss/client to my WEB-INF\lib
directory, with no more success.
I just get the 'Cannot instantiate class:
org.jnp.interfaces.NamingContextFactory' exception, although my code
executes successfully this line :
org.jnp.interfaces.NamingContextFactory ncf = new
org.jnp.interfaces.NamingContextFactory ();
Which means that it CAN actually instanciate
org.jnp.interfaces.NamingContextFactory, at least with the default
constructor.
