How to deal with “java.lang.OutOfMemoryError: Java heap space” error (64MB heap size)

Hi,

can anyone please provide setting the Java parameters from the command prompt...

I am getting the Exception in thread "main" java.lang.OutOfMemoryError: Java heap space in my program

Thanks

Are you certain this is not caused by a _memory leak_? If it is, adding memory will only increase the time between crashes. — Andrew Thompson, Mar 22 '11 at 10:41

You can set -Xmx:512M argument to increase maximum possible memory for usage.

There must not be a `:` in `-Xmx:512M`. It should be `-Xmx512M` (or `-Xmx512m`) if you want to set the max. amount of memory to 512 MB. – Jesper Mar 22 '11 at 10:32

When launching from a command prompt try increasing the memory allowance, eg:

eclipse -vmargs -Xms128m -Xmx512m

Where 128m is the min and 512m is the max heap size.
