Error Deploying TM1 Contributor 9.5.1 to Cognos 8.4.1

[comma]

I'm trying to install TM1 9.5.1 with Cognos 8.4.1 security. The installation of TM1 and Cognos went smoothly.
And then I tried to deploy the pmpsvc.war (the TM1 Contributor) to the Cognos 8.4.1 by copying the pmpsvc.war from <TM1 installation path>\Cadmin to <Cognos installation path>\webapps.

After that I tried to access the TM1 Contributor by opening http://[server name]:9300/pmpsvc, and I got this error page:

error cognos 8.4.1.PNG (34.34 KiB) Viewed 4689 times

I've tried to google "class file has wrong version 50.0, should be 49.0", and the results say that it's because the java.util.jar was created using JRE 1.6.0 but I tried to compile it using 1.5.0.
By looking at the folder name of my Cognos, which is saying c8_64\bin64\jre\1.5.0, I presume that Cognos 8.4.1 is using JRE 1.5.0.
Is this conclusion correct? If it is, than why is Cognos using JRE 1.5.0 while in the prerequisite they ask to install JRE 1.6.0?
I have installed JRE 1.6.0 update 22 too btw.

Thanks in advance for the help

Yes, cognos engines are 1.5 -- they aren't the same because it's not the same development teams - they don't write off a common platform.

Best results are obtained if you install Tomcat Apache (ver 6.0), and deploy the war to that. It keeps the jres separate, allows for customized java_home for Apache if needed (though undocumented for IBM's purposes), and does not overload the C8 service. (for anything beyond a few users, TM1 Contributor in C8/C10 services leads to performance issues in my experience). Also allows for 64-bit Java and Tomcat for TM1 Contributor.

Sorry, but I don't really understand your comment. Do you mean instead of using Cognos 8 to deploy the pmpsvc I should use Tomcat?
If that's what you mean then I cannot. Because I need the Cognos 8 to enable my Single Sign On.

Also, the strangest thing is I don't have this kind of issue in version 8.4.0 because in my Cognos 8.4.0's \c8_64\bin64\jre\1.5.0\lib folder, I cannot find any java.util.jar. So why is it required in the 8.4.1 version?

You install both, and you can still have single signon - there are just more configuration steps

I wouldn't know about that - we avoided any type of integration with 8.4.0.
