I am trying to run a Java Web Start application developed by me but when I run the jnlp, I get a security warning about the "Permissions" attribute being missing in the Manifest and the application does not run. I'm unable to understand why this happens as my manifest has the permissions attribute set in it using the line:
Permissions: all-permissions
Why is it then that running the Web Start says that the permissions attribute is missing ? Do I also have to include the attribute in every jar (in 'lib') that my code uses. If so, how do I modify 3rd party jars & set the permissions attribute in the Manifest ? Feedback on how to resolve this issue would be great. Thanks.
Update [16/07/14]: I've now added the Application-Name attribute in my jar's manifest file and re-signed it. When I run the jnlp now, there is no manifest permissions warning. I have left the 3rd party jars untouched so far. However, when the application starts the WebStart Console still states: "Missing Application-Name manifest attribute" & "Missing permissions manifest attribute". How do I solve this problem ?
Latest Update [18/07/14] Hi, I've managed to make my WebStart application run. However, it now first brings up a popup with the jar & its certificate's details. It then shows another popup with an error. I saw a post here with the same issue at Java Web Start manifest issue which provides the following solution:
In jnlpcomponent1.jnlp i see that sqljdbc4.jar is already signed by microsoft.
When i was looking to its manifest.mf it hasn't the attribute Permissions: all-permissions. So i delete all manifest file from sqljdbc4.jar and put an empty one (delete MSFTSIG.SF and MSFTSIG.RSA also). Build application again now with my signature and with Permissions: all-permissions in manifest file and works like a charm.
In my application, the 'jnlpcomponent1.jnlp' file contains four 3rd party jars that are already signed. My question is how do I unpack these jar's (to replace the Manifest with a blank one & delete the .SF and .HSA files) & re-pack it ? Please let me know. Thanks.
Update [21/07/14]: I have managed to resolve this issue myself. Thanks.
