Java EE (Java Enterprise Edition) General Discussion

Does any one know how to setup memory usage for Java VM, such as "-Xmx256m" parameter, in Tomcat?

I'm using Tomcat 3.x in Apache web server on Sun Solaris platform. I already tried to add the following line into tomcat.properties, like:
wrapper.bin.parameters=-Xmx512m

However, it seems to me that this doesn't work. So, how about if my servlet will consume a large amount of memory that exceeds the default 64M memory boundary of Java VM?

Any idea will be appreciated.
