Custom Locales deployment

Question

Hi,
I am trying to deploy a custom locale using Webstart but am unable to get the custom extension to deploy to the lib/ext directory of the current JRE. This is required for the application/java platfrom to detect the new locales.
I have tried using the Webstart extension tag in my JNLP but this has not worked (although copying the custom locales jar to the lib/ext directory of the JRE does work)
Below is a snippet of the JNLP that I am using:
<information>
  <title>Locale test</title>
  <security>
     <all-permissions/>
  </security>
  <offline-allowed/>
  <description>Demonstration of JNLP & Locale customization</description>
</information>
<resources>
  <j2se version="1.6+" />
  <jar href="test_locals.jar"/>
  <extension names="locales" href="locals.jnlp">
  <ext-download ext-part="locales" part="locales"/>
  </extension>
</resources>Any help that can be prvoided will be greatly appreciated :-)
Thanks in Advance,
Carl

Answer 1

A small error in the JNLP - the security tags should be outside of the information tags and the attribute of extension is name, not names:
  <offline-allowed/>
  <description>Demonstration of JNLP & Locale customization</description>
</information>
  <security>
     <all-permissions/>
  </security>
<extension name="locales" href="locals.jnlp">I have tried using a custom installer and copying the file directly to the lib/ext directory. This works fine except that I cannot get the JVM to load the custom format classes for the locale on the first load - in other words, I need to restart the JVM or add the classes to the classpath for these locales to be recognised on startup (the first time the app is started anyway)
I have tried adding the classes to both the System classloader (ClassLoader.getSystemClassloader, and to the parent of the ContextClassLoader (Thread.currentThread().getContextClassLoader().getParent()) but neither of those seem to affect the JVM that the application is running in.
Any ideas would be great.
Thanks,
Carl
