Problem Consuming Service From ES Workplace

[Former Member]

Hi all,

I tried consuming Service from ES Workplace (ReadPurchaseOrder) using NWDS 7.1 by following the blog

I configured all that is needed to consume a Service by following the same above blog. I successfully deployed my Project. But while Running my application, I was facing a problem as shown below.

Hi,

Please check JDK version deployed on your machine (or where you developed this code). goto command prompt and type:

Java -version

if it is not 1.5.x then upgrade it to latest version.

Hi

I have JDK 1.6 in my machine. I deployed on this only.

Netweaver CE 7.1 only support jdk1.5, while Netweaver 2004 and 2004s only support jdk1.4.

hi,

why not enter UnsupportedClassVersionError in google??

This results in about 37.000 hits for me, all basically saying the same: You compiled your classes against a certain Java version and try to run it on a VM of another version.
