Unable to launch the applications

Hi, I have a java swing application, I want to start it via jnlp, I configured my project web start configuration but when I push the launch button doesn't work. Do you know why?
Here is the error
Java.lang.NumberFormatException: For input string: "\Users\Administrator\Documents\NetBeansProjects\LoginPage\dist"

With just this error we can only tell you that your problem is happening because of a parseInt on a String that is not an int.
To correct this you have two possibilities :
add try{}catch(NumberFormatException e){//show error}
Assert that you have the proper things into parseInt ;)

I have the same issue.

How fix this ?

You spelled security wrong, you said secruity.

How to stop this error with selenium in Java and JFrame

I put together an app using java, selenium and JFrame. When I try to launch it in a JNLP page it gives me this error:

I have signed all selenium jar files contained in this jar.

I am trying to launch a Application.jar directly and com.simontuffs.onejar.Boot is the main class specify for JAR.

Since you're using the applet-desc tag, your Boot class must extend Applet (or JApplet). Based on the stack trace, it would appear that that class does not extend either of those.
If it's not an applet, use application-desc instead of applet-desc

NullPointerException when launching web start app

After finally solving the jar signing problem (thank you everyone for your help!), a new one has now come up.
When trying to launch the web start app from the launch.jnlp file I get the following error :
java.lang.NullPointerException
at com.sun.javaws.Launcher.executeApplication(Unknown Source)
at com.sun.javaws.Launcher.executeMainClass(Unknown Source)
at com.sun.javaws.Launcher.doLaunchApp(Unknown Source)
at com.sun.javaws.Launcher.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)
If I use the jnlp file that points to the jar file on my computer, the app runs fine, but if I try to use the jar file in the website - I get the above error.
What exactly is the problem?
The jnlp file has the right format, otherwise why would it work on my local jar file?
Here is the jnlp:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<jnlp spec="1.0+">

</jnlp>

Be sure that your JNLP file has the right format: http://download.oracle.com/javase/6/docs/technotes/guides/javaws/developersguide/syntax.html

I had faced similar issue. I was getting below exception while trying to launch
app through jnlp:

I have jdk 1.7 on my machine and any how some jar in JRE lib was missing or corrupted. I have resinstalled the JRE and it worked for me. I would suggest to figure out jar that is not getting picked up from jnlp file and relplace them and see if it works.
