How to pass java.library.path as a VM argument in JNLP file

Question

I jave a jar file containing reference to sqljdbc4.jar as I am using JDBC to talk with SQL Server. It works fine through eclipse IDE when I give the fillowing VM Argument
-Djava.library.path=C:\Users\reddys2\Downloads\sqljdbc_4.0\enu\auth\x86. Without this I get the "error message" saying that "failed to load sqljdbc_auth.dll
Now I would like to bundle working jar file in .jnlp and invoke through browser. I tried to add vm argunment (<property name="java.library.path" value="C:\Users\reddys2\Downloads\sqljdbc_4.0\enu\auth\x86"/> ) in the .jnlp file. But still i am getting "WARNING:Failed to load the sqljdbc_auth.dll cause:no sqljdbc_auth in java.library.path"
Any help is greatly appreciated. Here are the contents of JNLP file

Answer 1

Thanks for the pointer. Question that I have is I am referencing sqljdbc4.jar in my application, which in turn using sqljdbc_auth.dll.
Which one should i refernce through <nativelib>. Is it sqljdbc4.jar or sqljdbc_auth.dll.
have added the following line to the .jnlp.
<nativelib href="sqljdbc4.jar"/>
But still it is complaining on sqljdbc_audth.dll. If it is sqljdbc_auth.dll, can I use <nativelib> to pass it.
In that case does it need to be signed?. If so,
Is it possible to sign .dll using 'jarsigner'?.
