Native library usage

[pi4630]

Hi,

I have third party jar that makes use of native libraries.

I've created a new directory structure under modules as explained here and put all the native libraries in /lib/linux-i686. The module.xml looks like this:

{code:xml}
<?xml version="1.0" encoding="UTF-8"?>
<!--pi: this file modified according to https://community.jboss.org/thread/206389-->
<module xmlns="urn:jboss:module:1.1" name="com.canto.cumulus">
   <resources>
      <resource-root path="CumulusJC.jar" /> <!--third party jar-->
      <resource-root path="lib" />
   </resources>
   <dependencies>
      <system export="true">
         <paths>
            <path name="lib" />
         </paths>
         <exports>
            <include-set>
               <path name="lib" />
            </include-set>
         </exports>
      </system>
   </dependencies>
</module>
 {code}

On EJB jar side, the manifest file reads

{noformat} Dependencies: com.canto.cumulus {noformat}

I get the following exception when invoking the EJB service that makes use of the third party API:

{noformat}Exception in thread "main" javax.ejb.EJBException: Unexpected Error (...) Caused by: java.lang.UnsatisfiedLinkError: no CumulusJC in java.library.path {noformat}

I'd expect that the Jar is correctly modularized - but it obviously isn't. Any help would be appreciated.

and lib is under main and not on the same level?

[pi4630]

Yes, lib (with linux-i686 subfolder and its native libraries content) is under main directory.

How is the client called? If it's a completely external call I don't think it will even go through JBoss Modules.

             You should set the LD_LIBRARY_PATH or use -Djava.library.path=/path/to/my/dll in the java invocation so that your jar will be able to load the native library.

[pi4630]

That one is set, but stil yields the same error.

I then move the CumulusJC.jar to the same path, I get a slightly different (?) error:

javax.ejb.EJBException: Unexpected Error (...)

Caused by: java.lang.UnsatisfiedLinkError: com.canto.cumulus.Server.connectToServer1(Ljava/lang/String;ZLjava/lang/String;Ljava/lang/String;Ljava/lang/String;)Lcom/canto/cumulus/Server;

There is no chance you are picking up incompabile versions of the jar/dll?
