I'm currently expiriencing Java Heap Size error while trying to build a report in Eclipse.
I have an SQL query which is... I wouldn't say it is really large, but it isn't small.
First of all I couldn't create it norally in Eclipse Report Design always getting an error. So I created "Select '' as NAME, ... from dual' data set and modified the query in XML directly.

But when I try to view the report in Eclipse I get the error again.

Problem accessing /viewer/preview. Reason:

Java heap space

Powered by Jetty://

Ok, I need to put some Java parameters... But where to put them?
Modifying eclipse.ini didn't help.

Need an advice. Thanks.

Eclipse.ini would be the correct file to modify. Did you add the following parameter and restart BIRT?
Note that you can change 1500 MB (1.5 GB) to whatever amount of RAM you want to allocate to BIRT. The default is something like 512 MB.

You also might want to look at your dataset query result size. If you have a cartesian product or some really large resultset (like 800 million records), you might want to revise your query instead of increasing the RAM allocation.
