Webstart via jMonkeyPlatform Alpha-3 not working


I’m trying to run a webstart locally for a basic app via the jMonkeyPlatform Alpha-3.

I go on Properties of the project:


it generates me this jnlp:

[xml]<?xml version=“1.0” encoding=“UTF-8” standalone=“no”?>

<jnlp codebase=“file:/C:/Users/some_guy/workspace/Reaction/dist/” href=“launch.jnlp” spec=“1.0+”>



<vendor>Some Guy</vendor>

<homepage href=""/>


<description kind=“short”>Reaction</description>







<j2se version=“1.5+”/>

<jar href=“Reaction.jar” main=“true”/>

<jar href=“lib/assets.jar”/>

<jar href=“lib/jMonkeyEngine3.jar”/>

<jar href=“lib/jME3-jbullet.jar”/>

<jar href=“lib/j-ogg-oggd.jar”/>

<jar href=“lib/j-ogg-vorbisd.jar”/>

<jar href=“lib/jME3-lwjgl-natives.jar”/>

<jar href=“lib/jbullet.jar”/>

<jar href=“lib/jinput.jar”/>

<jar href=“lib/lwjgl.jar”/>

<jar href=“lib/eventbus-1.4.jar”/>

<jar href=“lib/nifty-1.3-SNAPSHOT.jar”/>

<jar href=“lib/nifty-default-controls-1.3-SNAPSHOT.jar”/>

<jar href=“lib/nifty-style-black-1.3-SNAPSHOT.jar”/>

<jar href=“lib/stack-alloc.jar”/>

<jar href=“lib/vecmath.jar”/>

<jar href=“lib/xmlpull-xpp3-1.1.4c.jar”/>


<application-desc main-class=“reaction.Main”>




I click the big green button and it gives me this error:


Is the lib folder created? If not, are you sure you have no folders in your projects libraries configuration? You probably get a warning during build in that case. Also, why are you using alpha-3? Alpha-4 is long out now.

thank you for the speedy reply.

I have installed alpha 4, let me say, it looks awesome.

Anyways, the problem persists, however, now the lib folder in the dist appears and the infamous “assets.jar” is there.

No warnings in that regard either.

Is there any other information I can provide?

The java console output.

i deleted some xml’s in the nbproject and it worked, thanks.

build-impl.xml and jnlp-impl.xml
