java.lang.OutOfMemoryError running demo sampl

2006-01-12 14:28

Using jasperreports-1.1.1-project.zip and following the instructions in readme.txt, I typed:


cd jasperreports-1.1.1/demo/samples

ant testAll


it runs the tests for a while, and then crashes with:



D:jasperreports-1.1.1demosamplesbuild.xml:439: The following error occurred

while executing this line:



Do I need to be passing parameters to java, such as

-Xms256M -Xmx512M -XX:NewSize=200M -XX:MaxNewSize=200M

and if so, where?

We are aware of this, but so far not able to find

the cause and to fix it.

The report compilation tasks seem to pile up

and consume memory when the JDT-base compiler is used.

Then, the other problem is that increasing the

memory available for Ant does not seem to help.


Anyway, I suggest to run the samples one by one,

when you need to see how a specific functionality

of JasperReports works.


Thank you,
