Java Connectivity Builder problem

[Former Member]

Disclaimer: I'm new with less than 3 months SAP experience.

I'm trying to run the Java Connectivity Builder and it keeps bombing with the same error:

Does anyone have any clue as to how to fix this issue?

I think I'm running R/3 and SAPJ2ee Engine 6.20 Patch 30 on my local host. My boss can get his to work and our app otherwise runs on my localhost, so I'm eliminating a SAP server issue and a J2ee engine issue. Any other ideas?

Definitely now that i read the last of your msg - you really shouldt run java abouve 1.3.1_x in 6.20 (its not supported) - 1.4.1_6 is the most you will get in 6.40 ... so the latest is not always the best.

I had this problem when i updated to a newer version of java - Revert back to JDK1.3.1_10 or what ever version you were using - or you can chang it in the batch file so you dont have to reinstall JDK - StartJCB.bat should now read

@ECHO on

SET JAVA_HOME="C:\jdk1.3.1_10\"

SET PATH="C:\jdk1.3.1_10\bin\"

start "java connectivity builder" C:\jdk1.3.1_10\bin\java -Xmx256M -Dlog.handler.RootConsole.level=WARNING -Dlog.handler.FileLog=FileHandler,log.txt -Dlog.logger.com=ALL,FileLog -cp lib/ext/aii_ifr_jbtool.jar com.sap.aii.ifr.tool.jbuilder.JBuilderTool

or similiar with your java_home pointed @ the old jdk

Hi,

Is last verion of Java CB , you want to use? Are you use it with IDE or standalone? I think so the problem i not related r/3 or J2EE engine.
