HELP! Error in connecting to EJB

[pop m]

I am using Orion 1.5.4 and SOAP 2.2 . I have written a simple stateless EJB and I want to call a method via SOAP but always I am getting the next error from client:     Fault Code   = SOAP-ENV:Server   Fault String = Error in connecting to EJB and my Orion app. server writes this:   Exception caught: javax.naming.NamingException: Error instantiating web-app JNDI -context: No location specified and no suitable instance of the type 'hu.regens. ejb.graph' found for the ejb-ref graph   However, I have tried to configure the "classpaths" to see my own EJB classes but it didn't work.   Can somebody help me ? If you'll get me an answer please specify what/where should I do/configure/try !   P.S. I have tried everything, even whether my autoexec.bat has been modified as you see below:   set classpath=.;.\classes;c:\java_classes;c:\jakarta-ant-1.4.1\lib\ant.jar;c:\jakarta-ant-1.4.1\lib\jaxp.jar; set classpath=%classpath%;c:\orion\applications\regens_app\regens_app-ejb.jar; (this contains my EJB classes)   set java_home=c:\jdk131 rem set java_home=c:\j2sdk1.4.0 set oracle_home=c:\orawin95 set ant_home=c:\jakarta-ant-1.4.1 rem set j2ee_home=c:\jdeveloper\j2ee\home set j2ee_home=c:\orion   Thanks !
