Exactly which Java Plugin version is used on the client? Also, are you using the WebUtil version that is included with Forms 11 or did you copy it from another version or OTN? You can get the WebUtil version by reviewing the Java Console when any WebUtil enabled form starts.
Thanks for the quick reply Michael!
Here's the java and webUtil versioning information.
Java Plug-in 10.21.2.11
Using JRE version 1.7.0_21-b11 Java HotSpot(TM) Client VM
RegisterWebUtil - Loading WebUtil Version 126.96.36.199
Just to explicitly answer your question; We have the webUtil version installed that came with the 188.8.131.52 upgrade.
Given what you have provided, I don't see an obvious issue that would cause what you are describing. However, without a working test case I may be overlooking something. I would recommend you contact Oracle Support and provide them with a simple test case so they can assist you further.
It does seem odd that you are getting a signing error. I suppose it is possible that you may be picking up a cached version of the jar file or there may be an issue with the JRE in use. If you are not able or willing to contact Support, I would recommend you do the following in this order:
1. Close all open browser
2. Clear the JRE cache. This can be done from the Java Control Panel
3. Uninstall ALL installed Java Plugins (JRE)
4. Install any one version other than 7U21
The results will help to partially prove whether or not there is an issue with the JRE.
Thanks for the reply Michael.
An SR has been raised with Oracle. No Resolution as yet.
We are facing the exact same problem.
Any luck with the SR? Is there a solution?
