Why TomCat runs out of memory on HTMLExport?

2003-03-26 09:21

JRHtmlExporter works fine for short reports

but on large reports (300pages)TomCat raises exeption:

at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:269)

 

At the moment of raising this exception I have a lot of physical memory available according to Win2k Task Manager.

 

JRHtmlExporter.java creates buffer and fills up this buffer with html.

I replaced appending to buffer with writing to file output stream in append mode and problem disappeared.

Now export takes comparable to PDF export time.

All other exporters except PDF have the same problem.

I hate changing the Jasper Reports source code.

 

What will be the other solution to this problem?

Hi,

 

Let your JVM use more memory by setting the

-Xmx command line switch.

Apparently you are running with the default value

which is 64Mb.

In Tomcat this is done by setting

the CATALINA_OPTS environment variable.

 

I hope this helps.
