java.lang.OutOfMemoryError

2005-05-10 19:55

Hi I am using Jasper Reports 0.6.4. My reports run into 1000 pages and I am using a lot of sub reports. I got outofmemory error and I tried to fix it by the solution posted at the following link....

 

https://sourceforge.net/tracker/index.php?func=detail&aid=1146354&group_id=36382&atid=416703

 

which is..............

 

cutting the try{}catch{} (with the wait statement inside

it) (in prepare method) in JRFillsubreport.java and pasting it inside the if(fillThread==null) {...} block.

 

I created a new jar of Jasper reports, but now I have the following error.......

 

java.io.InvalidClassException: net.sf.jasperreports.engine.base.JRBaseReport; local class incompatible: stream classdesc serialVersionUID = 606, local class serialVersionUID = 604

 

I don't know whether OutOfMemoryError is fixed or not..On the top of that now I have this error.

 

Can someone please help me ASAP...I have a deadline to meet soon (Friday).

 

Thanks in advance.

Venkat

Hi thanks for your information. java.io.InvalidClassException is fixed, but I am still getting the java.lang.OutOfMemory error. Any other patches and fixes for this error.

 

If needed I can attach JRFillsubreport.java to which I made changes trying to fix the OutOfMemory error.

 

Thanks in advance.

Redesign your query, they are too complex. In every situation where i had the out of memory error, a redesign of my query helped me out (stupid java database driver)

It's not possible in subreports only in your mainreport (subreports lose features like page footers and so on because it can't detect the page ending right)
