This is for the people who are using 220.127.116.11 Web launcher for EAS.
Everytime I try to open Business Rules (Expand Business Rules in EAS) from EAS I was getting the below shown error. (java.lang.NullPointerException)
I tried to look into the log files, but no luck there.
First thing was to see how to remove the JNLP file and I couldn’t find a way to uninstall it. (as I was getting an error while uninstalling it from Add/Remove Programs). You can force the Web Launcher to download the jnlp file again by clearing it from the Java Console.
But this didn’t solve the issue. Then the next step was to try and uninstall the latest JRE version in my system (JRE 1.6 update 18) and install an old one. (JRE 1.5 update 22)
That’s it, the issue was resolved. It was due to an incompatible JRE version. (I’ve though found the JRE incompatible issues with WebAnalysis only till now….but good to learn :))
