Re: exception when deployed on tomcat - Please help

How often do you want to ask this question again? An OutOfMemoryError is nothing GWT specific.

There are basically three ways to deal with it:

1.) increase Tomcat's heap memory

2.) load less stuff into memory before writing the file. E.g. use Input/OutputStreams along with fixed sized buffers instead of reading everything into a large String and then writing that large String to a File.

3.) If you think 1.) and 2.) are ok in your project then check for memory leaks by creating a heap dump and analyzing it

Google search has tons of results for all of the above points.
