Java jnlp application blocked by Security settings

I have an enterprise java application that has plenty of jars that are downloaded to the client's jvm cache by a jnlp file. When I start the application I get the following stack trace on Java Console:

I dont have any security restrictions for security on java control panel. It is at the medium level as follows:
Thanks for any help
New Edit: I got more explanatory stacktrace when I tried to run this jnlp from a jvm 1.6 machine as follows:
java.lang.NoClassDefFoundError: javax/ejb/EJBAccessException

I fixed this by going into the Java Control Panel (Start Menu > All Programs > Java > Configure Java) and adding two URLs to the Security Edit Site List.
http://code.google.com
http://androidscreencast.googlecode.com
For Mac System Preferences > Java
Where to add these sites
Java Control Panel > Security Tab > Edit Site List > Add > Apply > Ok

I tried to add the item file:/ and worked.

I recommend you to enable tracing and logging, see here how:
And then run the application from command line.
javaws -verbose AppName.jnlp
Then you could check for clues in log and trace files stored in this path
\Documents and Settings\<USERNAME>\Application Data\Sun\Java\Deployment\log
img source:
http://www.cisco.com/c/en/us/support/docs/security/hostscan/117097-trouble-java7-00.html

I had a very similar problem (Correctly signed JNLP application prevented from running in Java 7)
I fixed it by ensuring
I compiled using 1.7
I updated my JNLP file to enforce 1.7
<resources>
<j2se version="1.7*" java-vm-args="-Xmx32m" max-heap-size="32m" href="http://java.sun.com/products/autodl/j2se"/>

We saw this problem with Java 1.8u60 caused by dead references to icons in the JNLP file. Previously the missing icons were ignored, but now we are seeing failures with the stack trace in the question. Removing the references to the icons fixed our problem.
Here are the two references we removed:
<icon href="ORCL.jpg" kind="splash"/>
<icon href="ORCS.jpg" kind="default"/>
Hope that helps.

You can also try enabling the checkbox under Advanced tab of java (in controlpanel) and check mark the Always allow option under JNLP file section

On an Arch Linux system, I found the Java Control Panel to be accessible at /opt/java7/jre/bin/ControlPanel (a symlink to jcontrol). By running it, I was able to access the Security tab, and then crank down the Security Level to Medium. Then I'm prompted about accepting a security warning upon starting something like /opt/java7/bin/javaws.

Can't load FXML with webstart

First off my jar file works fine, but every time I try to start the .jnlp I get a runtime exception and this

I am using the generated .jnlp, even when I start fresh project and try to run the Hello World with FXML, I get the same error.
Before I added
<security>
<all-permissions/>
</security>
I was getting this error

I am trying to get this to run on a website btw, What am i doing wrong?

With JavaFX 2.2, you need to sign your app to be able to use FXML in a browser.
The JavaFX 2.2 FXMLLoader internally uses reflection to perform its work - and that won't work in the privileges afforded to an unsigned sandboxed application embedded in a web page.

To do that action, the JNLP file needs to declare:

My Applet is signed applet and all the DLL files inside applet are also signed with same signature.

Create other section in your JNLP file describing the native resources:
<resources os="Windows" arch="x86">
<nativelib href="jar-with-nativelibs.jar"/>
</resources>
(You don't have to use one jar for each os and architecture supported, but it's recommended)
And after that, define the java.library.path property:
<property key="java.library.path" value="." />
And you're good to go.

Upon running the JNLP file, I get the following Error:
JNLPException[category: Launch File Error : Exception: null : LaunchDesc:

I have signed all the jars except lib/org.eclipse.swt.win32.win32.x86_64_3.100.0.v4233d.jar - if I sign that one too, I get a different exception:

After doing "javaws -viewer" and re-running the JNLP, I get:

You have to sign the jar file. You can do this yourself using keytool, but if you plan on deploying this, I would recommend getting it signed by Verisign or a company like it.
If you just need a temporary fix, signing it yourself for testing is fine.
Here is an easy to use tutorial.

All jars must be signed with the same signature.

All jars in one jnlp need to be signed with the same signature, use an extension with its own jnlp for jars that are signed by third parties.
Some jars use the original signature in the jar for crypto (the JDBC driver for SQL server) others do not work when re-signed (javahelp.jar)
You can also save the trouble signing them by including this in your application's jnlp:
<extension name="javahelp" href="javahelp.jnlp"/>
