Deploying Webservice: Unsupported major.minor version 49.0

[Former Member]

Hi,

I made a webservice, now I'm trying to deploy it, but it gives me this error:

java.lang.UnsupportedClassVersionError:

at/vai/edilog/webservice/UserManagementBean (<b>Unsupported major.minor version 49.0</b>)

I read that this could be caused by compiling on Java 1.5 and running it on Java 1.4. I actually had 1.5 installed, but I had the compiler-compliance-level in eclipse set to 1.4.

I then installed Java 1.4.2 (same version as J2EE) and rebuild the project, but I still get the same error when deploying.

Any idea why this happens?

Thanks and regards,

I solved the problem by actually deinstalling the Java 1.5 completely.
