Hello,
We are on PI 7.0 SP10.
Currently we are migrating the XI servers from Solaris to AIX IBM.
When I try to run Java mapping, I get following error:

But this note says
>> The error is corrected with Support Package 5 for Support Package 03 for the XI TOOLS 3.0 software component.
and I am already on PI 7.0.
Please tell me still I need to apply this?
Thanks,

In respect to class loaders and JREs, what are some of the scenarios that could result in class version mismatch errors at runtime?
I am assuming it will have to do with .class file's version stamp being different in different class loaders within the same JVM....can someone please shed some light on this. Thanks!Actually I think it would only happen if you're using a class that was compiled on a sufficiently newer compiler than the JVM you're running it on. As long as the JVM can handle all classes it's been given, I don't think the classes can mismatch among themselves.
But check the language spec or the JVM spec to be sure. -

XI Mapping: Class versions are incompatible (linkage error)
Hi,
i have a simple File-to-File scenario, and I am getting the following error as observed in the XI Monitor:
<SAP:Category>Application</SAP:Category>
<SAP:Code area="MAPPING">LINKAGE_ERROR</SAP:Code>
<SAP:Stack>Class versions are incompatible (linkage error)</SAP:Stack>
To troubleshoot the mapping, I have removed all mappings, and put the target nodes to constant values. I am still getting the error in Mapping (linkage error).
I am using XI3.0SP0 (J2EE SP07, ABAP SP3). Is this a known problem / OSS notes available ? thanks.

Linkage error occurred when loading class MyClass
Hi
I have written one simple class name MyClass and i have created jar file and i imported into import archive... but in interface mapping while i am testing i am getting the <b>"<b>Linkage error occurred when loading class MyClass"</b></b> error.... why i am getting this error
Thanks & Regards
Ravi Shankar BHere it goes:
Symptom
The LINKAGE_ERROR error occurs during the mapping.
The trace contains "java.lang.NoClassDefFoundError: Illegal name":
Other terms
XI 30, Mapping, Linkage Error
Reason and Prerequisites
As of the jdk 1.4.2_05 from Sun, this program error occurs during the mapping in the runtime or during testing in the Repository. This error may also occur in conjunction with jdks of other vendors or other versions.
Solution
The error is corrected with Support Package 5 for Support Package 03 for the XI TOOLS 3.0 software component.
Import the corresponding archive SAPXITOOL03P_5.SCA for SAP Exchange Infrastructure XI 3.0 as described in the Netweaver 04 Support Package Stac Guide.
You will find the archive and the guide in the SAP Service Marketplace under the alias "SP stacks -> SAP NetWeaver -> SAP NetWeaver 04".

Incompatible Xalan version in IDE class path? (Max OS X Leopard)
Hi all,
I have been using NetBeans 6.1 for a while and all was well. I then installed a few plug-ins (including iReport, which I believe may be the problem). When I start the IDE I get the error "Incompatible Xalan version found in IDE class phat" and gives some link that didn't help. I have uninstalled NetBeans and reinstalled, which obviously didn't fix the problem. If anybody can help me at all, I would appreciate it very much. I really need this to run, I would hate to completely reinstall the OS to get it back going. Thanks in advance for any support.
Edited by: JavaChip on Jul 7, 2008 4:32 PMHi,
I encountered this problem today and I'm also using Netbeans 6.1 on Mac OS X (10.5.4). It was definitely the iReports plugin. I found a solution here:
[http://blogs.sun.com/geertjan/entry/analyzing_the_jasperreports_visual_designer]
However, I only had to remove the file xalan.jar (and keep xalan-2.7.0.jar) from the ~/.netbeans/6.1/modules/ext directory. No changes to the config were required and the iReport plugin worked.

Hi Friends,
I am getting LINKAGE ERROR when executing JAVA mapping as its not able to reference AbstractTransform class provided by SAP PI API.
This problem occurs in particular environment for this particular mapping. For other environments this is working fine.
I assume it has something to do with Java Library reference which is mis-configured during transport. Can anyone let me know how and where the library path is configured for Imported Achieves in SAP PI 7.1.
We are using java 1.5 for building and creating java achieves.
Many thanks,
SKHi Sumant,
This error occurs when the jdk version of XI server and the library version you used to develop the mapping are incompatible. Make sure you use the same version as of the server
have a look in SAP Note 755302

How to avoid Linkage Error in JAVA Mapping
Dear Experts,
I am trying to test the JAVA mapping compiled in NWDS but receiving the error
"LinkageError at JavaMapping.load(): Could not load class".
java.lang.NoClassDefFoundError: JSONXMLProject/bin/com/sap/json/ConvJson2Xml (wrong name: com/sap/json/ConvJson2Xml)
at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClassCond(ClassLoader.java:735)
at java.lang.ClassLoader.defineClass(ClassLoader.java:716) at java.lang.ClassLoader.defineClass(ClassLoader.java:537)
at com.sap.aii.ib.server.mapping.execution.MappingLoader.findClass(MappingLoader.java:195)
Following are the details:
SAP PO 7.4
SP Stack Number 05
JDK Version jdk16
NWDS
SAP Enhancement Package 1 for SAP NetWeaver Developer Studio 7.3 SP10 PAT0000
1.Created the Project , Package and then class (Included the logic)
2. Included 1 JSON Jar file into my project and the Added to build path.
3.Exported the project as Archive File and saved in desktop
4.Imported into SAP PO system as Imported Archive
5.Could not observe the JSON jar file which i used as referenced JAR in NWDS
6.Tested in OM after referencing the JAVA class and found the above error.
I have JDK 5, 6 and 7 present in my local desktop and I am trying to export the compiled code using both JAVA SE 1.6 and 1.5 in NWDS seperatly after going several discussions.
Can any one hep me with the screenshots and tell me how to include all the reference jar files in exported project..
Regards..Dear Anand,
I did exactly as you shared. As the JSON jar has number of classes, then in OM all the Classes had to be assigned. Then the linkage error went.
But in execution , it shows a new error that all the classes of the JSON jar has to be implemented with interface StremTransformation or AbstractTransformation.
I assume in the Operation Mapping I will use only 1 class as JAVA Class. Anyway I am attaching the document with navigation.
Do we have any other alternative??
Please rename the extension of the document by remove .txt

Linkage Error while setting up webApp
Hi,
In my webApp I bumped into following Exception while running JSPs which queries
database.
Platform : Windows NT 4, webLogic 5.1 with SP 8.
Action : WLSServer crashes with Dr. Watson application error.
I am using a custom Connect.java class ( through javax.sql.DataSource, as recommended
by WLS 5.1 docs ) to connect to Oracle database using JDBC thin client. If I do
not use webApp architecture then the same class works good to connect to DB.
Also, if I maintain identical class hierachy into my weblogic.class.path classpath
settings I do not get this exception and everything works fine.
I read into this search group messages about Linkage problems caused because of
having duplicate classes available to the server at runtime and so I ensured that
I do not keep classpaths which can cause duplicate classes into runtime environment
of wlsserver but still the same problem persists.
any help is appreciated,
thanks,
- Rajesh.

Hi again
Plase check you JAVA_CLASSPATH and WEBLOGIC_CLASSPATH variables
make sure the paths. May be, the script that you use, define the class in
the incorrect path

Class Not Registered error upon using MS Office Report
Hello,
Using LabVIEW 2010, I've just installed the Microsoft RGT trial from NI, along with the Office 2010 trial from Microsoft. Upon trying to drag the MS Office Report VI to my block diagram, the configuration dialog appears but immediately an error dialog shows up over top, with a Class Not Registered error. Attached is the screenshot. If I close the error and try to configure the VI for a basic Excel report, I get a file-not-found error in reference to the Excel template, which I have verified is indeed at the target path and opens with my version of Excel just fine. Any ideas how to get past this error?

It sounds like you have to reinstall the RGT. Have a look at this documentation.

Linkage error while doing java mapping
Hi,
I Have written a java mapping but when i use it in xi.It is showing an error as linkage error
LinkageError at JavaMapping.load(): Could not load class: com/satyam/nestle/JavaMap
Can anyone explain what does this mean and how to overcome it.
Thanks in advance,
BhargavDid you try testing the java mapping seperately....that it does not have any errors??? Also check the cahce update. Sometimes it happens that XI is not able to load the class file from the cache. Perform a CPA cache refresh (delta). This should solve the problem

Class not found error afer loading classes to oracle
hi i have loaded quite a few jars into oralce 11g databse
created a java stored function
and executed it
some times it works... and hits the java front end environment... we are hitting a servlet.. and recording some output statements .. in the function
but sometimes it throws class not found error
any idea why its working sometimes and not some othr times?
Also when i load the jars.. the classes are loaded but when i see the name of the classes using
select * from user_objects where object_type like 'J%'
then i see some additional characters prefixxed the class names ... is that causing the problem?
something like this

Obviously you need to learn how to ask a question.
There is nothing in your post other than 'It doesn't work. Why? Help"
without any specific example. Also you still fail to include a 4 digit version!!!
It is also the third or the fourth time you asked this very same question.
Can you learn how to ask a question please? And stop repeating the question when you don't get a response?
And no, the extra characters are not the problem.
An incorrect CLASSPATH probably is.
