Well, I am able to create reports but and I can see the paper reports in 10g W2K but when I try to see the web report created by report builder, I get an error in the browser: *--------- 500 Internal Server Error OracleJSP: oracle.jsp.provider.JspCompileException: Errors compiling:C:\Documents and Settings\nflorez\Local Settings\Temp\docroot\3000\default\defaultWebApp\persistence\_pages\\_MODULE200802632.java error: Invalid class file format: C:\oracle\product\oradevsuit10g_home1\j2ee\home\oc4j.jar(com/orionserver/http/OrionHttpJspPage.class), wrong version: 46, expected 45 C:\Documents and Settings\nflorez\Local Settings\Temp\docroot\3000\default\defaultWebApp\persistence\_pages\_MODULE200802632.java:9: Superclass com.orionserver.http.OrionHttpJspPage of class _MODULE200802632 not found. public class _MODULE200802632 extends com.orionserver.http.OrionHttpJspPage { ^ 2 errors *---------- I think that it might have to do with java but I really do not know what to do here. I made sure that my JAVA_HOME is pointing to my j2sdk1.4.2_04\bin directory but it still did not work. Any ideas?
