Java web start + jnlp + no lwjgl in java.library.path

Troubleshooting General Help
1

Hello,

i'm having this classical problem with "no lwjgl in java.library.path" while using java web start. following my jnlp-file:


<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="1.0+" codebase="http://139.30.101.246/ship3djmonkey" href="index.jnlp">
   <information>
        <title>Degrees of Freedom</title>
        <vendor>maring</vendor>
        <description>Degrees of Freedom</description>
        <description kind="short">Degrees of Freedom</description>
    </information>
 
   <security>
           <all-permissions/>
     </security>

   <resources>
        <j2se version="1.6"/>
        <jar href="ship3djmonkey.jar"/>
   </resources>

    <resources os="Windows">
      <nativelib href="lwjgl-native-windows.jar"/>
    </resources>
    <resources os="Linux">
       <nativelib href="lwjgl-native-linux.jar"/>
   </resources>

   <property key="java.library.path" value="." />

   <application-desc main-class="de.uni.rostock.maring.Ship3dApplication"/>
</jnlp>



and this is the folder, where all the jars etc. are in:

what may be the problem??? i try to figure it out since three days ...

Doesn't it automatically add the contents of the native jars to the library path and thus the line

<property key="java.library.path" value="." />

is actually overriding that and messing your path up?



By the way this is a complete guess as I've never used web start  :expressionless:

i deleted the line <property key=“java.library.path” value="." />, cleaned browser cache and got the same error messages, shown below …

You might want to give this a try:

I still use it from time to time. :slight_smile:

you dont have lwjgl.jar in resources ?

<resources>



<j2se version="1.5+"/>



    <jar href="yourgame.jar" main="true"/>



    <jar href="lwjgl.jar" />



    <jar href="jme.jar" />

   



</resources>

ha! no! i have no lwjgl.jar in my jnlp-resources! i try to change now my application's folder structure (now the lwjgl.jar is in there) to that way you suggested.

@ mud2005: THANK YOU!!! It works now!!!

@ darkfrog: your webstart creator gave me nearly the same jnlp-file that i had before (except the main="true" attribut). so i knew the error must be somewhere else. thanks for that, too!! nice little app!



to whom it may concern: my problem was solved while i did this:

  1. making a signed jar of my application (used fatjar). in this jar there were all the jme-jars in the lib-directory, except the lwjgl.jar (the one that needs the native libs)
  2. making a signed jar from lwjgl.jar
  3. making signed jars of the native dlls (helpfull was http://www.eclipse.org/swt/jws/)
  4. making this jnlp-file (useful was darkfrogs webcreator):


<?xml version="1.0" encoding="utf-8" standalone="no"?>
<jnlp spec="1.0+" codebase="http://139.30.101.246/ship3djmonkey" href="index.jnlp">

      <j2se version="1.5+"/>
        <jar href="ship3djmonkey.jar" main="true"/>
      <jar href="lwjgl.jar"/>
   </resources>

    <resources os="Windows">
      <j2se version="1.5+"/>
      <nativelib href="lwjgl-native-windows.jar"/>
    </resources>
    <resources os="Linux">
      <j2se version="1.5+"/>
       <nativelib href="lwjgl-native-linux.jar"/>
   </resources>

   <property key="java.library.path" value="." />

   <application-desc main-class="de.uni.rostock.maring.Ship3dApplication"/>
</jnlp>


5. putting all the signed jars and the jnlp-file in one directory
6. ready!!!
