All,
I am having some trouble running a java web start application that has been generated by Netbeans 7.
I have migrated my existing java 6.9.1 application to Netbeans 7 and attempted to make it a web start application.
To do this I have checked the Enable Web Start option from the project properties.
For the codebase option I have Web Application Deployment selected.
The Application descriptor is selected option which will point the JNLP application-desc element to my applications main class.
For signing, I have generated a key and pointed the Signing properties at this. I have the Mixed Code set to Trusted Only as my application will only used signed JARs.
When I compile, all referenced JAR files and the application JAR file are signed which is output in the console (for each one) as:
Signing JAR: D:\MyCode\dist\lib\somejarfile.jar to D:\MyCode\dist\lib\somejarfile.jar as signFiles
Enter Passphrase for keystore: Enter key password for signFiles:
NOTE: signFiles is the alias I have used in the Signing properties in Netbeans.
The following files are created in my dist folder:
- lib
- jnlpcomponent1.jnlp
- launch.html
- launch.jnlp
- README.TXT
- My App.jar
I have copied these to my web folder that is hosted under tomcat which is C:\Program Files\Apache Software Foundation\Tomcat 7.0\webapps\mywebapp.
I am running from the following URL in IE and Firefox:
http://mylaptop:8080/mywebapp/launch.html
The following exception is thrown when I click the button in launch.html to launch the JNLP file:
com.sun.deploy.net.FailedDownloadException: Unable to load resource: file:/C:/Users/panderson/AppData/Local/Microsoft/Windows/Temporary Internet Files/Content.IE5/B3UCQV8C/$$codebase/launch.jnlp

My launch.jnlp file has the following:
<jnlp codebase="$$codebase" href="launch.jnlp" spec="1.0+">
...
<resources>
<j2se version="1.6+"/>
<jar href="My App.jar" main="true"/>
...
I am not too sure why it is looking under the temp folders in internet explorer for it…
… But I have tried putting the full url in the jnlp href to the launch.JNLP file http://mylaptop:8080/mywebapp/launch.jnlp then it throws the following exception:
com.sun.deploy.net.FailedDownloadException: Unable to load resource: file:/C:/Users/panderson/AppData/Local/Microsoft/Windows/Temporary Internet Files/Content.IE5/DR2O6URQ/$$codebase/My App.jar
If I then change the jar href to http://mylaptop:8080/mywebapp/My App.jar, the following exception is thrown when I click the button in the launch.html to run the launch.JNLP file.
BadFieldException[ The field <jnlp>codebase has an invalid value: $$codebase,$$codebase]
Any help or thoughts?
Cheers,
Andez
These $$ place-holder values are usually translated to something sensible by a servlet or similar functionality.
