I am facing a performance issue while exporting data from DB2 to Excel 2003. Well the very first reason is file is about 10+ MB where it goes outofMemory Exception. I am using XLSTransformer and HSSFWorkbook classes to transform my xls file. I also have joins in my query( optional). But user most likely is going to choose these options. When they do so, of course, the data becomes huge and take lot of time and some times goes outOfMemory too.

So Please advice me on this.
