HTTP 500 error
We are running WebFocus 5.26 NT with Tomcat, and our MRE OLAP reports were getting an HTTP 500 error on large reports. The exact error message is:

"An HTTP 500 error has been returned when attempting to communicate with the WebFOCUS web components. ..."

Tech support determined that the problem was with the java heap size. For those who are interested, here is the solution:

To set the registry settings properly on increasing the heap size, please follow the instructions below:

1. Go to your <TOMCAT_HOME>\bin directory
2. Double click on tomcat5w.exe
3. In the dialog box, Click on the Java Tab
4. Under Java Options, add -Xms256m on one line and -Xmx512m on a new line 5. Add the necessary value to the Thread Stack Size (in KB)
