MII 12.2 - IE11 & Java 8, Missing Permissions manifest attribute in main jar

[Former Member]

Hello All,

We are having issues with the MII 12.2 applets/illum8.zip being blocked and java security popups with IE11 & Java 8.

Our MII 12.2 application works fine with IE11 & Java 6.  The application also works fine with IE8 (64-bit browser) and Java 1.8.0_20 (64-bit java).  The java blocking/security popups are occurring with IE11 & Java 8 (both 1.8.0_20 and 1.8.0_60).  Since the applications works fine with IE8 and Java 8 (no popups at all), it seems like it may be a IE11 issue?

The first error in the Java 8 console is:

Missing Application-Name manifest attribute for: http://(server-name)/XMII/Classes/illum8.zip

Then get many errors, I believe one error for each java applet:

Missing Permissions manifest attribute for: http://(servern-name)/XMII/Classes/illum8.zip

We have tried adding our url to the Java Exception Site List.  This reduces the number of popups but it is still slow. When trying to run our application out of the SAP Portal, it is really slow.  I was able to get the MII 12.2 Workbench to open up with Java 8 by adding the url to the Exception Site List, but this is not a good solution for the application.

I have spent quite a bit of time searching in SAP Service Marketplace as well as internet but have not found a good solution.  Does SAP have a solution for this issue?

In SAP 12.2 SP08 documentation, it referred to one of the issues fixed was: 2099319 - MII 12.2 Sp07 Patch 1 Applet permission issue.  Is this the fix for this issue?  Would installing 12.2 Service Pack 08 resolve this issue?

We are at SAP MII version 12.2.5 (build 66).

Thanks

I was able to disable the security warnings but am still getting the Missing Permissions manifest attribute for: http://(server-name)/XMII/Classes/illum8.zip in the java 8 Update 60 console.  The application comes up quickly and can activate a Search button which responds back normally, but when I navigate to other pages in the application, the response time is very slow.  It writes the message: Missing Permissions manifest attribute for: http://(server-name)/XMII/Classes/illum8.zip each time an applet request is made and each time it does this it takes 10 to 30 seconds.

After researching further, from Oracle.com web page, "The JAR file manifest contains information about the contents of the JAR file, including security and configuration information.".  It sounds like maybe the illum8.zip needs to have permission attributes added to the manifest before the JAR file is signed.

Is 2099319 - MII 12.2 Sp07 Patch 1 Applet permission issue, the fix for the jar file manifest security attributes issue (Missing Permissions manifest attribute for: http://(server-name)/XMII/Classes/illum8.zip)?

Thanks in advance
