Hi

PI 7.1 supports Java 1.5, so install JDK 1.5 and check this version u are using.look which Java version is selected. follow path

Control Pannel->Java->Java Tab->click on View(Down side) now look which JDK version is selected on your machine.

Hi Dharamveer,

I have seleceted Java 1.5 in the Java tab... but I still face the same issue.

Arvind ,

this problem seems to be related to your client not with the server. as you can cross check this thing by opening the mapping form any other colleagues system. so kindly uninstall any java web start version greater then 1.5 . and don't check the auto update option in ur machine .

once you will revert back to 1.4_2 even 1.5 everything will be fine..

Issue with out of Sync SCA...SCa with SP06 and SP 07 were mixed up. After a full deployment of SP07 all SCa the the problem was resolved.

Hi Arvind,

I'm currently having the same problem with PI mappings not opening. I believe it may have been caused by a imcomplete 7.1 SP07 installation.

Can you please provide more details on exactly which SCA's you applies to fix the problem.

thanks,

Ben

Did you get this fixed? We are having the same problem with QA but it works in DEV. Do you have any suggestions?

[Former Member]

Can you elaborate on the solution for a novice please?

[dharamveer_gaur2]

I think you developed mapping with lower Java version.Mapping Jar for PI 7.1 is com.sap.xpi.ib.mapping.lib.jar

Compare with PI 7.0 aii_map_api.jar .

HI

class incompatible: stream classdesc serialVersionUID

This is a version mismatch problem. Whats the version you have on your server and system. Another thing if you migrated external mappings from PI 7.0 like Java maps etc. You need to compile them again with higher version to avoid this mismatch.

Try opening with lower version of Java webstart as well.

Thanks

Hi Arvind,

Restart the java server from smicm and restart the ESR session.
