Java.lang.OutofmemoryError while loading message in mapping

Question

Hi,
I encountered a Strange problem while performing message mapping.
I have to transform Orders05 message into another message format(the size of the XSD file is 17 KB) which has got 100 elements(approx count) in it.
After selecting the source message(Orders05) when i tried to select the target message (whihc was imported into XI as external definations), the system hangs up and i get below error message.
<b>Display Problem
java.lang.OutofmemoryError
Internal problem occurred (INTERNAL_PROBLEM)
MESSAGE ID: com.sap.aii.utilxi.swing.framework.rb_exceptions.INTERNAL_PROBLEM</b>
The system i tried this was a P4-processor512 MB RAM. so i used my laptop(1 GB RAM Intel centrino) to perform the same. But no change in message mapping, but the only thing i noticed was the system did not hangup.
Later i went to perform the same mapping on the server 3 GB RAM, dual processor. Initially the message could be selected as target field. But after performing 2-3 field level mapping, the Design time hanged up. I had to close the session and open up again to perform 2-3 field mappings again. This went on for over 20 times and only then i could finish the entire mapping.
I have never encountered such a problem earlier. Is there any solution to rectify this. My problem is, i have to perform 10 such mappings :-((
Here is the complete errror i got .

Hi Siva,
Goto the exchange profile via URL
http://<>:port/exchangeProfile, goto
IntegrationBuilder in the left tree and increase parameter com.sap.aii.ib.client.jnlp.j2se.maxheapsize from 512m to 768m (or higherif necessary). Press the save button.
Goto http://<>:port/rep/support/admin/index.html,
press AII Properties on the left side and then press the REFRESH button until you see the new value on the right side.
if the problem is no resolved even after doing the above, take a look at a look at note:

(This note is also valid for XI3.0)
