Do you have the JBoss jars and JNDI correct --

Try copy/paste the below and name it run.bat (in the last line java -cp %myCLASSPATH% %myD% client change client to whatever your client's name is):

Looks sloppy here but if you cut/paste into text editor will look normal (this is Windows version but you can adapt for UNIX if needed):

set myCLASSPATH=%CLASSPATH%;.;%JBOSS_DIST%\client\concurrent.jar;%JBOSS_DIST%\client\gnu-regexp.jar;%JBOSS_DIST%\client\jaas.jar;%JBOSS_DIST%\client\jacorb.jar;%JBOSS_DIST%\client\jboss-client.jar;%JBOSS_DIST%\client\jboss-common-client.jar;%JBOSS_DIST%\client\jboss-iiop-client.jar;%JBOSS_DIST%\client\jboss-j2ee.jar;%JBOSS_DIST%\client\jboss-jsr77.jar;%JBOSS_DIST%\client\jboss-net-client.jar;%JBOSS_DIST%\client\jboss-system-client.jar;jars\jbossha-client.jar;%JBOSS_DIST%\client\jbossmq-client.jar;jars\jbossmqha.jar;jars\jbosssx-client.jar;jars\jcert.jar;jars\jmx-connector-client-factory.jar;jars\jmx-ejb-connector-client.jar;jars\jmx-rmi-connector-client.jar;jars\jnet.jar;jars\jnp-client.jar;jars\jsse.jar;jars\log4j.jar
set myD=-Djava.naming.factory.initial=org.jnp.interfaces.NamingContextFactory -Djava.naming.provider.url=localhost:1099 -Djava.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
java -cp %myCLASSPATH% %myD% client
pause

The log you have posted doesn't has any reference to EJBModule. That is when you deploy an ejb corretly the EJBModule logs a message whith the ejb name.
It looks like if the jar file doesn't has the deployment descriptor files corretly. Check the META-INF directory and the deployment descriptors in the jar file.
