JNLP Applet + nativelib + UnsatisfiedLinkError

[Sagar Rohankar]

Hi all,

I'm developing a Java 3D Applet using JNLP Applet Plug In. In this applet I'm using JNA for loading my library(dll) which is used by the applet business code.

Ican load all the 5 libraries (4 for Java 3D and 1 for my applcation library). I use the custom Class Loader.

Now the problem is, when I load Java 3D jars and dll, the system throws "UnsatisfiedLinkError" for not finding the "CLP.dll" library, BUT it load the same lib and execute w/o any problem if I don't load the Java 3d libs ??

What are the possible cause, any kind of help will be greatly appricaiated.

<resources>

		<jar href="lib/CLPApplet.jar" main="true"/>       
		<jar href="lib/jna.jar"/>										
</resources>
	
<resources os="Windows" arch="x86">
		<!--<extension name="Java3D" href="java3d.jnlp"/>-->
		<nativelib href="lib/java3d.jar"/>
		<!--<nativelib href="lib/clp-dll.jar"/>-->
		<extension name="CLP" href="clp.jnlp"/>		
</resources>

2 things:
1. I'm not able to figure out whether this is JNLP or JNA problem ?
2. My custom class loader loads all the .dll into the "Temp" (Windows %TEMP%) directory renaming the dll like "extensionXXXX.dll" and overrides the java.lang.ClassLoader#findLibrary() method.

I don't know what's going wrong here, but I've been able to get native libraries to work with applets by using the JNLPAppletLauncher class.

Yes, the JNLPAppletLauncher is the next thing I'm thinking to try out ;)
It may be the custom class loader which messing the things up.
