UnsupportedClassVersionError

Hi
I am trying to build a simple web service and a web service client using JAX-RPC. i am using sun application server. the web service is deployed in the server and i am able to open the WSDL file also using the browser. the web service client is also compiled with out any errors. but when i try to run the client program i get the following error -
Exception in thread "main" java.lang.UnsupportedClassVersionError: javax/activaion/DataHandler (Unsupported major.minor version 48.0)

i searched regarding this error and found that there could be some problem with the tools.jar file i.e some incompatibility in the jar file used by the server and the one used by the jdk. but the versions of my jdk and the version of jdk in the server both are same. how do i overcome this problem...

Probably you have compiled your java code with a recent jdk. But the application server, where you have deployed your application, uses an elder jdk.
To solve the problem you should specify the version of the target jdk when building your application. To do this on command line, use the -target option of javac. To do this on ant, use the target attribute of javac task.

AP 7.00 IPC VMC Log Error UnsupportedClassVersionError

Greetings all!
I've converted our IPC 4.0 java routines in preparation for our CRM 7.0 upgrade.
I've uploaded the new JAR file, and configured the new routines in the /SAPCND/UEASS transaction, and finally cleared the IPC buffer.
When we enter an order the result is an error in the IPC stating my routine has an UnsupportedClassVersionError and trhrows the following error in the VMC logs:
Execution of function module SPC_CREATE_DOCUMENT failed
--> java.lang.UnsupportedClassVersionError: com/osi/pricing/userexits/value/ZValue606 (Unsupported major.minor version 49.0)
Any thoughts on what the problem is here?
Regards,
Tim

Check the compiler (Java) version of the developer. Got to match the VMC allowed versions.
Tip: Though Eclipse may require latest version to run, it can still compile and generate Class files with any Java version you require. Got to configure Eclipse.

How do you fix UnsupportedClassVersionError

I have created an application that will run on any computer with the JDK. I want to make it an executable file so that you don't have to have the JDK to run it. I downloaded a Native compiler that will compile your Java application into an executable. It asks you for two things: The directory with all your application's .java and .class files. It asks you to specify a main .class file. It comes with a few sample applications that you can compile. I am using the most simple one the hello world application. Here is the hello.java file
public class hello
static public void main(String args[])
System.out.println("Hello, World!");
Now, this file came in a directory with the files hello.class and hello.java. If I use the native compiler (Excelsior JET is it's name) and i specify the directory that contains the hello.class and hello.java file as the application's working directory, and Hello.class as the main class and then click test, the native compiler will run the hello world application just fine. After testing I can click compile and it will turn that application and to a hello.exe file that will run on any windows computer without a JDK. Now, if specify the information for my own Java application, (which would be it's working directory C:\Vocab\) and Vocab.class as the main class, the native compiler will not be able to test and certainly not compile it and it and will give me this output:
The application has started with command line:
java -cp C:\Vocab Vocab
Exception in thread "main" java.lang.UnsupportedClassVersionError
at java.lang.Void.<unknown>(Unknown Source)
at java.lang.Void.<unknown>(Unknown Source)
at java.lang.Void.<unknown>(Unknown Source)
at java.lang.Void.<unknown>(Unknown Source)
The application has terminated with exit code: 1
You see the part that says java -cp C:\Vocab Vocab? If I type that into the command prompt, my application will run. So why wont it run here? I think the answer lies here:
Before you begin
Before using Excelsior JET to compile your Java application, make sure that the application runs properly on the reference implementation of the Java platform, such as Sun JRE 5.0.
Ok that is in the help section that comes with Excelsior JET, the main compiler. Now back to that hello world application. As i mentioned before it comes with the hello.java and hello.class file. I can take that hello.java file and use either jGrasp, Netbeans, or go to the directory
C:\Program Files\Java\jdk1.6.0\bin and use the javac.exe file to generate a hello.class file. Now if I take that hello.class file that was generated from the hello.java file that was in the hello world directory, and overwrite the hello.class file that came with the native compiler, I can try testing the compiler but i just get the same error that i get when trying to test/compile my own application. Let me clarify:
hello.class that came with the compiler will test and compile
hello.class that i made with jGrasp, Netbeans, or Javac will not test or compile.
So what do I use to create the proper .class files that will test/compile?

That means the box is having trouble communicating to the VOD servers. Please reseat the coax cord from both ends (the wall end and the box end). Once the coax cord is back on, reboot the box by unplugging power cord for 20 seconds then plugging back in. If you continue having problems with the VOD connectivity, please send me a private message so I can get your info directly.

Java.lang.UnsupportedClassVersionError with ADF and Websphere

I'm trying to get an app running with ADF/Tomahawk/MyFaces/Facelets going on Websphere 6.0. However Websphere is running with a 1.4.2 JVM instead of 1.5 so I get an error when it comes to the ADF NavigationHandlerImpl which has been built with Java 1.5. Is there a Java 1.4 version of ADF faces I should have downloaded somewhere?
Hints appreciated.

Hi,
you will have to compile the application with JDK 1.4 in this case. This should work for JSF and ADF Faces.

Java.lang.UnsupportedClassVersionError in Import Java Classes

Hi,
I have recently upgraded to Forms Developer 10g (10.1.2.3) and JDeveloper (10.1.3.4). I have recompiled my classes in JDeveloper, and when I go to Import them into my form I get
Exception occurred: java.lang.UnsupportedClassVersionError: classes/eps/palms/pickup/client/ResultSpec (Unsupported major.minor version 49.0).
Has anyone any clues as to how to resolve this?
Thanks
Margaret

Yes, the new version of JDeveloper must have the compiler default set to 1.4 or 1.5. Enforce it to 1.3 if you want to use the Bean with the JInitiator.

SGD Portlet - Failed to build using Ant - UnsupportedClassVersionError

Hi,
I've downloaded the Sun Secure Global Desktop portlet source code from here: https://portlet-repository.dev.java.net/public/Download.html and I'm trying to compile it using Ant.
I have Ant 1.7.0 and I'm using JRE 1.4.2_15. For some reason, the Ant task fails. Using the -debug and -logfile options, it points to a VersionTask class error:

I know this portlet code was just released this week, but has anybody had any success building the portlet into a .WAR file?
Thanks in advance!
Rob.

I figured it out... the tarantella-tasks.jar file had class files in it that were compiled using jdk 6, and the rest of the project was compiled using jdk 1.4.2. Luckily, the source code was there so that I could recompile the classes back to 1.4.2 and it now works.

Java.lang.UnsupportedClassVersionError: per/model/mac/Hrxss_Per_Subtype_Inf

Hi,
I have copied the essper application from inactive dc's and changed the visibility property to be derived dynamically depending on the subtype being displayed.

My compiler compliance level is 1.4 and I am deploying the applications using jdk1.4. Could you please assist?

hi,
you may get some idea from below lines
I changed the compiler complience level to 1.4 and deployed the application using jdk1.4. However the error was still there. When basis team checked the development config for PCUI_GP, it was sitting on SP03 which they then updated and the problem was fixed. Now I am getting a java.lang.UnsupportedClassVersionError on a different wd componet.
Thanks !

Java.nio package Runtime error java.lang.UnsupportedClassVersionError.

Hi
I am using nio package and create a java program for file locking (FileLocking.java).
Here is the sample
try {
file = new File("C:/acc.txt");
channel = new RandomAccessFile(file, "rw").getChannel();
     lock = channel.lock(0, Long.MAX_VALUE, true);
try {
          lock = channel.tryLock(0, Long.MAX_VALUE, true);
catch (OverlappingFileLockException e) {
return true;
using wsad 5.1 and jdk1.4 i compiled this program.

please suggest me how can i overcome this problem.

UnsupportedClassVersionError means that you are trying to execute a class for a newer version of the JVM on an older version of the JVM.
Version 48.0 is for Java 1.4, so you have compiled your class with JDK 1.4.
The computer you are trying to run the class on, has an older version of Java than 1.4 - check it!
Try recompiling your source files with the "-target" switch, for example if you're running on Java 1.3, try compiling with:
javac -target 1.3 ... FileLocking.java

UnsupportedClassVersionError in WASD

I am creating a simple java project in WASD (WebSphere Studio Application Developer Version: 5.1.1 )
but just changing compiler compliance level to 1.4 from 1.3 .
when I run a class it gives me UnsupportedClassVersionError
I don't know what is the problem ?
pls help

Having same problem as mentioned in this thread only getting it when try to run the demo webDynpro apps provided with NWDS.
Root Cause
The initial exception that caused the request to fail, was:
java.lang.UnsupportedClassVersionError: Bad version number in .class file
at java.lang.ClassLoader.defineClass1(Native Method)
After 3 installs now with different JDK's last was JDK 1_5_15 .. can't find update 12 anywhere as perscribed in earlier threads. Anyone figure out a way to resolve this without have to play shell games with JDK's. Speaking from new SAP Netweaver Guy considering jumping from ledge.
Thanks.

Hi,
I had the same problem. I got the sam advice about the 'two versions' story.
I was running java programs for Java 1.5 under Win ME (please don't laugh). I then I upgraded to XP. I re-installed Java 1.5. Suddenlu those same programs that were running under ME won't run under XP. Getting the same message as above.
I only had 1 (one) Java version installed. That was Jave 1.5
The funny thing is that jsp pages that I created under ME still worked fine under XP without me doing anything to them
I un-installed Jave 1.5, re-install it and what do you know? Everything is fine now?
It's a strange, strange world we program in, Master Jack (taken from a hit song in the late 60's in SA - need I say more?)

JDBC error : UnsupportedClassVersionError:Bad version number in .class file

Hi All,
I am currently working with PI 7.1 on an Idoc ->XI->JDBC scenario. The DB being used in our case is SQL 2008. We have successfully installed the JDBC driver provided by MS. When the message reached the JDBC the following error is listed in RWB.
JDBC Message processing failed, due to Error when attempting to get processing resources: com.sap.aii.af.lib.util.concurrent.ResourcePoolException: Unable to create new pooled resource: DriverManagerException: Can not establish connection:: UnsupportedClassVersionError: Bad version number in .class file
We tried reinstalling the JDBC drivers as well , but to no avail.. .
Any idea on why this could happen ?
Regards,
Sandeep

Hi Mallikarjun,
Are you getting this error for only specific channel or all channels?
If you are getting this for all channels check your drivers of they are installed correctly....
if it is for specific channel then try increasing JDBC thread count and in restart the channel...
Regards,
Naveen

I looked up some of the discussion in the forums they had mentioned try
"javac OutFirstProgram.java - source 1.4 - target 1.4", I tried the same but still in vain.
The code I took it from one of the boook, but when I literally type on the editor and then run the program it works perfectly fine and the complete program is the same, i did not change anaything, but why is there is change. I am not able to undetstand the reason, could somebody throw light on this and also let me know to solve the problem.
PK

Hi,
Thanks. I tried the following and it worked:
javac -source 1.4 -target - 1.4 OutFirstProgram.java
But, I am compiling the source code using the same machine and same location and also running it from the same location and machine, so how can the change be. Also my java version provides this output, which says they both are same right:
java version "1.4.2_05"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_05-b04)
Java HotSpot(TM) Client VM (build 1.4.2_05-b04, mixed mode)
I am not clear why is this problem happening.
It would be nice if you could provide me a way by this can be solved permanently not providing source and target and each and every time I run the program.
