To start our legacy application, we use java WebStart via a jnlp.
We would like to support 64-bit Java clients but one of our libraries is architecture dependent.
We thought of doing something like:
<resources>
<j2se version="1.6+" sun.arch.data.model="64"/>
<jar href="/apps/swt-3.7M5-win32-win32-x86_64_s.jar" download="eager" />
</resources>
<resources>
<j2se version="1.6+" />
<jar href="/apps/swt-3.7M5-win32-win32-x86_s.jar" download="eager" />
</resources>
This is not working because the parameter sun.arch.data.model="64" is used to set the parameter instead of testing on it.
Any ideas?
This is explained in the documentation, here: http://docs.oracle.com/javase/7/docs/technotes/guides/javaws/developersguide/syntax.html#resources
It doesn't say which arch
values make sense, though. You would want it to work for different JVM implementations and versions. I googled around for a while and here's what I've ended up using:
<resources>
<java version="1.6+"/>
<jar href="lwjgl-2.8.4.jar"/>
<jar href="lwjgl_util-2.8.4.jar"/>
</resources>
