Java Heap space error when creating dataset

[rodnikosh]

on the iReport 4.8.0,

i create a new dataset and choose 3 tables for the dataset to include,

when i push "next" i get the error : "Java Heap space"

searched this forum and tried the solution suggested and nothing helped.

i tried changing the ireport.conf file values from :   -J-Xmx512m    to -J-Xmx1024m or even -J-Xmx2048m.    it doesn't change anything.

also checked "use visualizer" but i don't know what it is and how to work with it.  anyway, checking the "use visualizer" didn't solve the problem.

 

any more ideas ?

Strange. You might consider not using the "wizard" based query creator, instead right click on the root report element and "Add Dataset" - choose "Create and Empty Dataset"

Once you've done this right click on the dataset and click "Add Query"
