Re: [xmlvm-users] Problem with Cross Compilation using XMLVM

[Nikolai P. <ni...@np...>]

Hi John,

You should put un argument to let java use more memory. Try executing the same command, but with "-Xmx2G" argument:

java -Xmx2G -jar xmlvm.jar --in=/HelloWorld.class --target=iphone --iphone-app=TheApplication

Regards,
Nick
