Unable to launch the applications

问题

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"

回答1:

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.
Netbeans 8.01, JDK 1.8u20, JRE project,

Run option:

'run as webstart' enabled.

Application/Webstart options:

Created Certificates Keystore (Tip: i used 'portecle' )
Codebase: Local execution (by which the preview shows: 'file:/C:/..../')

The JNLP which is created by the project says;

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<jnlp codebase="file:/C:/<snip>/dist/" href="launch.jnlp" spec="1.0+">
