UDF and imported Archives

[Former Member]

Hi,

We've created two classes in a package and created a jar file. Then we imported the JAR into the a namespace as an Imported Archive. In our UDF we imported the package. But when we test the map we get the following exception.

<b>bad class file: /usr/sap/XXX/DVEBMGS00/j2ee/cluster/server0/./temp/classpath_resolver/Map85e140e0dd6c11db8894001125a5ce17/classpath/CustomExceptionHandlers_0(xxx/xx/xi/mapping/udf/MyTestClass.class) class file has wrong version 49.0, should be 48.0 Please remove or make sure it appears in the correct subdirectory of the classpath.</b>

Does anyone have an idea on the cause of this error?

hi...

i had a similar problem some days back.....

while making jar, pls compile the java file with a jdk having a same or lower version of jre that ur JAVA stack is using.....and BETTER test it outside XI in a standalone programme to see that the JAR is working fine and all classes are in proper hierarchy...

pardon me...........for mistakes

Thanks everyone for your inputs. I had just installed 1.5 for another application we are using; but the XI 3.0 environment is using 1.4. When we imported the jar which was created with 1.5 into XI the version conflict occured.

Thanks again...

Hi Gilder,

The same problem was solved here

Java 1.4 creates class files labeled with version 48.0

Java 1.5 creates class files labeled with version 49.0

Java 1.4 can't run class files labeled with version 49.0

49 is the correct classfile version for 1.5.

If you're getting this error your runtime is 1.4 or earlier while your compiler is 1.5.

Hope it helps u out

Gilder,

It is complaining about the wrong versions. Why dont you recreate the jar files and reimport the archives and check?
