jars no longer seem to be signed. JARSigningException: Found unsigned entry

Question

NB 7.4RC2, Win 7

In Java Control Panel, the "Keep Temporary Internet Files" checkbox is checked.

I am signing my Web Start application with trusted certificates. However, the 3rd party jars in dist/lib seem to be unsigned.

C:\Program Files (x86)\Java\jdk1.7.0_40\bin\jarsigner" -verify javafx-dialogs-0.0.3.jar

jar is unsigned. (signatures missing or not parsable)

So when I run my application in the debugger, it refuses to start complaining of unsigned jars

ExitException[ 3]com.sun.deploy.net.JARSigningException: Found unsigned entry in resource: file:/C:/Users/me/Documents/NetBeansProjects/MyApp/dist/lib/RXTXcomm.jar

I get the same error when I run with self signed jars, “Found unsigned entry in resource”. It is as if NetBeans stopped signing the jars.

I deleted all temporary files in the Java cache from Java Control Panel. Now it fails to run clicking both Run and Debug in the IDE, and also copying the dist folder to the desktop and clicking the jnlp file.

ExitException[ 3]com.sun.deploy.net.JARSigningException: Found unsigned entry in resource: file:/C:/Users/me/Desktop/dist/lib/RXTXcomm.jar

while building:

........

security: Trust for: file:/C:/Users/me/Documents/NetBeansProjects/MyApp/dist/lib/RXTXcomm.jar has ended: Wed Dec 31 18:00:00 CST 1969

Does anyone know what is causing this?

Update: In NetBeans, I selected Project Properties and under Run, selected Run As “default configuration”. Earlier, Run As “WebStart” was selected. Now it starts normally. Was it a NetBeans bug or a feature?

Solution

WebVPN Java Plugins fail to load after upgrade to Java 7 Update 45 with the following General Exception error - 'com.sun.deploy.net.JARSigningException: Found unsigned entry in resource:

Conditions: Windows or Mac OSX machines using Java 7 Update 45.

Workaround: 1) Disable the option 'Keep temporary files on my computer' on the Java Control Panel -> General -> Settings. This works for both Mac OSX and Windows.

or

2) Downgrade Java to version 7 Update 40 or below

I am having the same issue. I created a JavaFX project, added some deployment configuration (sign enabled, signing certificate), and running as Standalone works fine, but running as WebStart, or simply opening the generated html (with it's applet) or double-clicking the JNLP file, displays the same exception. I realized that toggling "Enable BLOB Signing", generates different content inside the built Jar's META-INF folder.
