I am having the same problem. The server cant seem to find my appmodule .properties file. I have included it in a jar file in the J2EE/HOME/LIB folder and also set the classpath to it. Yet i keep getting "JSP Registry could not locate runtime property file:MyProject2_package1_Package1Module.properties" The same exact jar files in IPlanet run just fine. Also, this only happens when i use JSP pages built from using Oracle provided beans. The JSP pages built with TAGS do not pose this same issue. This is propably because on the JSP's that use the beans there is a call: oracle.jbo.html.jsp.JSPApplicationRegistry.registerApplicationFromPropertyFile(session , "MyProject3_package1_Package1Module"); Also when i remove this call from all the pages i still get the same error.
This project i created just by running the BC4J JSP application wizard - nothing fancy, just scott emp/dept tables. has anyone got this to work? <HR></BLOCKQUOTE>
Ditto. I have spent hours with this exact problem. In the end, I reverted to deploying my existing code to 9ias 1.0.2.2, ie not using the OC4J engine. My code which worked with earlier versions of ias (including 8ias and 1.0.2.0) suddenly had a problem in 9ias 1.0.2.2 finding my connection file. It appears to be a general problem with the ClassLoader and the path of the resource.
Shahbaz, have you tried to run your generated JSP with the BC4J against 9ias (just using Apache and the Oracle engine) ? Do you get different results ?
