increase memory of created jar-file

[Heiko Gleitsmann]

Hi folks,

i´m developing with eclipse and export the imageJ project as a jar file. if
i start imagej.jar the memory is limited to 64 mb (please correct if i´m
wrong). And now the question: is it possible to change respectively increase
the memory of the running jar file? I know that there exists the file
IJ_Prefs.txt, but there i can´t find something that has to do with memory.

Please help, thanks in advance

You have to call java appropriately:

        java -Xmx128m ij.jar

for 128MB. The problem with IJ_Prefs.txt is that it is read only when Java
is _already_ started (with 64MB).

Hth,

Hi Johannes,

thanks for the help, it works. But I think you have to call:

java -jar -Xmx128m ij.jar     ;-)
