I am trying to deploy an application that uses the **native** implementation of Tibrv through the **TibrvJ** library using **Java Webstart**.

I have packaged up all of the Windows *dlls* from inside `c:\tibco\tibrv\bin` into a Jar file and have added these to the `nativelib` element in the **JNLP** file. 

I was hoping that webstart would take the *dll* files from the`tibco-7.5.1-nativelibs.jar` file and allow them to be loaded via `System.loadLibrary` which is called from `Tibrv.open()`. However it doesn't seem to want to work properly.

My **JNLP** file looks like this:

```

 </resources>
 <application-desc main-class="com.somewhere.Main">
  <argument>classpath:/live/client.xml</argument>
  <argument>/live/live.properties</argument>
 </application-desc>
</jnlp> 

```

The application launches but as soon as a call is made to open tib then it falls apart with an error along the lines of:

* [Root exception is TibrvException[error=22,message=Version mismatch: libtibrv version 7.4 does not match version of tibrvj shared library 7.5]]
* TibrvException[error=901,message=Library not found: tibrvj]]

The users have a **variety** of Tib installations already on their PCs from Tib 7.2 through to 7.5. The Webstart Application only works correctly on a machine with 7.5 installed which matches the Jar file inside the package. So it doesn't appear to do anything with the nativelib jar.

I would like to avoid having to deploy 3 versions of the web start application for the different versions of Tib that the users have installed.

Has anyone else managed to get this combination of **TibrvJ** and **Webstart** working?
