.JNLP does not work

Hi

I created a jnlp file to run java code on my website. After I did all the steps that are mentioned in Deploying a Java Web Start Application (The Java™ Tutorials > Deployment > Java Web Start).

I opened the jnlp and then the java GUI did not show up and also it didn't give me any errors. The jnlp code:

Code:

---

<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="1.0"
codebase="http://albunian.webs.com"
href="ClipJNLP1.jnlp">
<information>
<title>Clip</title>
<vendor>Sun Microsystems, Inc.</vendor>
<offline-allowed/>
</information>
<resources>
<jar href="ClipJAR4.jar" main="true"/>
<j2se version="1.3+" href="http://java.sun.com/products/autodl/j2se"/>
  <j2se version="1.3+"/>
</resources>
<application-desc main-class="ClipPackage.Clip"/>
</jnlp>

Could you please help me to find a solution ?

Does the code in the jar file execute OK by itself?
I see that the .class files were created by java 1.7.
Are you using a 1.7 version of java to execute it?
