rowset.jar WAS 5.1problem in WAS 6.1

Question

currently I'm running my application under WAS 5.1 with rowset.jar working fine, but when upgrade server to 6.1, getting error with rowset.jar as below

java.lang.UnsupportedClassVersionError: (javax/sql/rowset/CachedRowSet) bad major version at offset=6

do anyone face the same problem, how to solve this i try to with different version of jar but not solve,

thanks in advance

Answer 1

That error indicates that the javax/sql/rowset/CachedRowSet class you are trying to use was compiled to Java 6 bytecode.

As far as I know, WAS 6.1 uses a Java 5 runtime:

E.g., for WAS 6.1 JVM:

> java -version
java version "1.5.0"
Java(TM) 2 Runtime Environment, Standard Edition (build pwi32devifx-20080907 (SR8a + IZ29767 + IZ30684 + IZ31214 + IZ31213))
IBM J9 VM (build 2.3, J2RE 1.5.0 IBM J9 2.3 Windows XP x86-32 j9vmwi3223ifx-20080811 (JIT enabled)
J9VM - 20080809_21892_lHdSMr
JIT  - 20080620_1845_r8
GC   - 200806_19)
JCL  - 20080907

So you need to find out why you are using a Java 6 compiled version of rowset, and change to Java 5.

Again, as far as I know, WAS 6.1 comes with the javax/sql/rowset/CachedRowSet class, so you shouldn't need to bundle it yourself.
