Solution for "Could not create the Java Virtual Machine"
The problem: we wanted to give more memory to Blast2GO running on Windows 7 x64, but we kept getting the error *beep* "Could not create the Java Virtual Machine".
Looking at the makeJnlp.php file that the Blast2GO website gives you, I noticed the max-heap-size line:
<jnlp spec="1.0+" codebase="http://bioinfo.cipf.es/blast2go/webstart" href="http://bioinfo.cipf.es/blast2go/webstart/makeJnlp.php?mem=2048">
<information>
<title>Blast2GO 2048M</title>
<vendor>CIPF - UPV - IVIA</vendor>

<resources>
<j2se version="1.5+" initial-heap-size="64m" max-heap-size="2048M"/>
...
When I removed the max-heap-size assignment the JNLP file started just fine with Java Web Start (javaws.exe). Conclusion: somehow the machine could not actually allocate the amount of heap space we were asking for.
Sure enough, further investigation showed that the 32-bit version of Java had been installed instead of the 64-bit version.
After installing the 64-bit version and running the JNLP file with 64-bit javaws.exe, everything was fine.
JNLP heap size
Hi,
I have the same problem, but my JVM is 64 bit. As soon as I increase heap size from 1024M to 2048M I get "could not create Java Virtual Machine". Any other ideas?

]Thanks a bunch Len, this
Thanks a bunch Len, this helped me out a bunch. I wish there was a bit more information in the warning message. I changed my heap size down to 512M from 1024M and things worked just fine.

]How do I work it
Hi, I also keep getting the "Could not create the Java Virtual Machine" ...... How do I change my heap size down to 512M from 1024M to see if this makes it work?

This might seem like a dumb question, but where can you change the heap size?

]I tried changing
I tried changing -XX:MaxPermSize=1024m to -XX:MaxPermSize=768m, and it works.. I'm using eclipse for development, you may see the settings in the .ini file inside the eclipse folder (if you're using eclipse).
