Hi all,
I need a bit of advice on an application I have that reads in an XML file and based on its content generates a text file which is used by another application.
I have written my application to handle the XML file using JDOM. So when the XML file is read in it creates a JDOM Document which I then use to access the Elements I need to create the text file. However I have now run into some memory problems and am questioning the wisdom of using JDOM. The XML files I have to handle are much bigger then I had anticipated (they are around 1MB) and as a result I was getting OutOfMemory Exceptions when executing my application. I have had to increase the
Java heap size to 400 MB to get my application to execute successfully. I have watched the memory usage of the application while it is running and it hits 393MB. This seems a bit crazy. Should I definately migrate my code to use the SAX API??
Also as an aside, if I had to deal with an even larger XML file which required me to increase the Heap size to greater than 400MB whats the max size that I could set the heap given that my machine has 522MB of RAM??
Thanks for your help...
John
