heap size problem!!

specfy it using the ANT_OPTS env var

http://ant.apache.org/manual/running.html

you mean I have to add ANT_OPTS to enviroment variable??
could you pleas give me the full syntax I should put ??

I mean what should I put exactly in the enviroment varaible ?

eg. to set it to 512Mb

ANT_OPS=-Xmx512m

ANT_OPTS=-Xmx512m

Thank you, I'll try it tomorrow morning and I'll send back the result :o)

that's doesn't work!!
I've tried to set ANT_OPTS from the command prompt:
set ANT_OPTS = -Xms512m
set ANT_OPTS= -Xmx512m
It has been set successfully, but still get outOfMemory Error !!

What I'm trying to do is writing a JUnit testCase for a method in a class, this method returns the sum of size of 3 ArrayLists in this class, in that method I want to check if the counter == Integer.MAX_VALUE then return Integer.MAX_VALUE!!

To be able to test this method I have to set the three Lists to number of elements it exceeds Integer.MAX_VALUE, so when calling size() method it will return Integer.MAX_VALUE!!

This is the testCase, but It gives me outOfMemory during adding elements to the lists:
public void testCollectionView1Accuracy1() throws Exception {
            for (int i = 0; i < Integer.MAX_VALUE / 2+100; ++i){
                  collection.add(new Character('A'));
            }
            for(int i = 0; i<Integer.MAX_VALUE/2+100; ++i) {
           elementsToAdd.add(new Character('A'));
        }
        collectionView = new CollectionView(collection, elementsToAdd, null);
            assertTrue("size() incorrect.", collectionView.size() == Integer.MAX_VALUE);
    }

what should I do??

that requests a lot motre than 512Mb doesn't it?
why does the test need to add so many elements to the collection?

The class is wrapper for some collections in java, I'm using it as a view so it allows to filter the collection, makes changes on it without affecting the original collection.

>>why does the test need to add so many elements to the collection?
to check if size() method returns Integer.MAX_VALUE if the sum of the three lists exceeds it!!
in the real-world this wrapper class will hold a large number of records from database, for large systems.

mmm!! I see, so my laptop won't handle it :o)

thank you very much,
I really appreciate your help :o)
