Hello,
I Installed SAP JAVA GUI (recent version 7.30rev5) on Linux with recommended Oracle Java (recent version Java SE 7u45).
The Java GUI works fine as standalone, but fails to run as an applet in a browser (e.g. Firefox).
Starting the applet html, I get the following steps:
- I'm asked to activate Java(TM) plugin
- I'm asked to run com.sap.platin.GuiApplet2
- then I get the error 'RuntimeException: java.lang.reflect.InvocationTargetException'
I tried to use different versions of SAP Java GUI, Oracle Java versions (up to Java 8) and Java Sources.
The only solution to get the applet running is to downgrade to Java version 7u40. Since this is not save anymore, I'm not satisfied.
I found hints why this is not working (Java security changes):
http://scn.sap.com/docs/DOC-49944
http://www.segal.org/java/SignedAppletTest/
http://service.sap.com/sap/support/notes/1831420
There are workarounds, but they seem not to work.
Even I don't use the Java GUI as an applet, it would be interesting to know, if other Javva applications are affected too and if there is a solution yet.
Thanks
Peter
