Memory allocation for Java Webstart Application -
i'm using java webstart application called blast2go i'm running problems memory allocation. needs load large data set memory, i've been trying allocate 3-6gb application. however, no matter set max heap size, uses 455mb (as indicated message bar: 'memory usage: xxmb of 455mb'). i've tried setting reasonable levels (1024 mb), still 455mb allocation.
any ideas?
btw, i'm using ubuntu 10.04 32-bit 24gb memory, 8 procs.
update: here jnlp provide. same result when edit values of initial-heap-size , max-heap-size attributes.

> javaws blast2go3gb.jnlp error occurred during initialization of vm ccoouulldd nnoott crreesaetrev et heen ojuagvha svpiarcteu aflo rm aocbhjiencet. heap final update: turns out problem java version. got expected behavior when downloaded , used sun java.
if running 32-bit linux, can run 32-bit jvm limited 4 gb memory per instance. believe case if have more visible kernel.
if really, need lot of memory in single jvm need go 64-bit.
edit: java webstart not open sourced openjdk alternative implementation used. try download , use sun java instead. should enough download , unzip jdk, , run bin/javaws foo.jnlp.
