getConnection() causes a OutOfMemoryError

2003-03-20 17:40

I have a report and a subreport.For the subreport,

I am using a Map to pass as a parameter a Connection for the connectionExpression(the value of that I get through DriverManager.getConnection()).Whenever is executed,it causes a OutOfMemoryError exception.Anybody has experienced a similar situation.


Genri !

If there are many records in the datasource,

use the -Xmx switch in the command line to

allow the JVM to use more memory when you

launch java.exe.


I hope this helps.

The report and the subreport work fine separately.The problem occurs whenever they are put together.The records returned are not that many (range of 10s and dealing with a small test DB).Could it be a jdbc driver problem..thanks
