Deployement of application java.lang.UnsupportedClassVersionError

[Former Member]

Hello,

I have to deploy applications from SAP NetWeaverDeveloper Studio. Unfortunatly, when I try to test my application I always have the following error:

java.lang.UnsupportedClassVersionError

I already try to change my JDK version to 1.5 (such as suggested on http://help.sap.com/saphelp_nwce711/helpdata/en/f3/cc6570aec14890b3f6b327825d6313/content.htm)

but it still doesn't work.

Do you know how to configure correctly SAP NetWeaverDeveloper Studio?

For information I use SAP NetWeaverDeveloper Studio 7.0.15

Hello Julien,

the link you provided points to the NetWeaver CE Help which is the wrong one in your case.

You need to install the JDK 1.4.2.x on your lokal development system since you are deploying to the 7.0 WebAS.

Kind Regards,

Hi Julien,

The recommended JDK version for NWDS 7.0 is 1.4.2.

You will find below note related to JDK version in NWDS 7.0 installation guide.

"Note that since Sunu2019s Java SDKs are downward compatible, SAP NetWeaver Developer

Studio should work as normal with higher JDK versions. However, as Java Sun SDK 1.4.2 is

the only version that we officially support in SAP NetWeaver 7.0, we discourage the use of

any other version with the Developer Studio."

Many Thanks

Mahesh

Hello,

thanks for your reply. For information, I installed j2sdk-1_4_2_19 and now it is working fine.

Next versions seem not working.
