I have encountered a strnage problem, please tell me what I have dome wrong: in my Admin Console, I set up the following Connectin pooling, jndi: jdbc/myDataSource ejb, jndi: ejb/myEjb and I tried the following: when I install a WAR module alone, and WAR module did not use any EJB, and I did not specify the "Resource Reference", then to look up for the data-source, jdbc/myDataSource, it works when I package my WAR module together with EJB module to an EAR file, what the folowing step: if I specify that the WAR use the DataSource, by setting the "Reference Resource", then I can get the DataSource with the jndi look up string: "jdbc/myDataSource" in my code, it worked fine but if I also specified that my WAW module also use the EBJ, by setting the "EJB reference" in the WAR module, then I cannot obtain the Datasource anymore? I dont know what shou;d do then? thank you vey much
