LINKAGE_ERROR

Hello ,
We are getting a LINKAGE_ERROR at the message mapping step on (runtime) and while testing the message mapping we are getting the CLASS_NOT_FOUND error.
This happens for all scenarios and not the case with any particular scenario.
After reading some of the threads , I checked the note 755302 which surely has the correct symptom
but its applicable for XI 3.0 and we are on 2004 s.
Please advise.
Mathews

Thank you guyz for your replies...Let me try to explain this a bit further.
Initially I got this error while testing a graphical mapping which was a straight forward ,source structure to JDBC UPDATE_INSERT structure without any functions or UDFs.
Then to check whether its my mapping problem I created some simple two field mappings as well , but all has the same problem now.While testing the mapping using the test tab you get the 'Class "com.sap.xi.tf._ <message mapping name> not found'
It gives a linkage_error while running the interface (runtime)
We tried restarting the Java Stack but with no luck

Mapping - LINKAGE_ERROR

hi,
My scenario is Proxy to File. On execution of this scenario, I am getting error "LINKAGE_ERROR" and the description of the Error is "Incompatible class versions (linkage error).
I am on XI 7.0 SP 10.
Initially, I had a proxy error. On analysing, we found that the JAVA stack was upgraded to Patch SP10 whereas ABAP stack was still SP06. Therefore, we now patched the ABAP stack to SP 10. Thereafter, we generated the proxy for a test scenario and it worked.
Now that for a different scenario, we generated a proxy. It is now giving the LINKAGE ERROR. We thought it would be a compatibility issue between the ABAP and JAVA stack as the ABAP stack was upgraded a bit later. So I regenerated the PROXIES and activated them. Still I get the same error.
Can anyone thro' light to fix this issue.
Regards.
Balakrishnan

I agree, this is a mapping specific error, not related to the proxies anymore.
If you use only xslt's or message mappings, make dummy changes so that the internal java classes are rebuilt. If you use java mappings, make sure you build the .class files with a compatible (1.4.2.x) JDK.

I have tried compiling the code in the same JRE as the one in PI. Still it is not working.
Please suggest.

Hi all... thank you for the replies.. I have compiled the code in the same version of JRE as the PI version...
Hi Vijay,
I also felt the same but as I do not have much knowledge in JAVA, i could not track it further.
below is the code for the mapping... would you mind if I ask you to have a look at it and let me know where the error is..
thank you so much ...

Java Mapping PI 7.0 to 7.1

Hi,
The below mentioned code is for sending email with attachment using Java Mapping which was implemented in PI 7.0
I know the API for PI 7.1 has changed, I changed the below code using extends AbstractTransformation using Transform instead of implements streamTransformation and few other changes but I get lot of issues.
Could anyone point out what and all need to be changed in PI 7.1 for the below mentioned code. It would be greatly if anyone could let me know the changes

I am sure that I need to do include some library files, but I couln't figure it out. Couls you pls help to resolve this. The following library jar files were included
activation.jar
aii_map_api.jar
com.sap.xpi.ib.mapping.lib.jar
jce.jar
mail.jar
JRE System Library.............is anything else missed out??
By the way I included all these in Netweaver Developer studio , in JavaBuildPath ->Libraries.
Added those jar files as external jar's for development and then compiled it and exported as DynamicConfMailJar and imported in PI .
could anyone help?

Java Mapping Issue

Hi,
I'm new to JAVA mapping and I'm having an issue which I can't get resolved :

I'm using eclipse for the java class and I have choosen several jre versions to create the .jar file but all lead to the same error.
I had copied the required aii_map_api.jar.jar from xi box to my local project directory and added it as an external .jar to my project.
But since I new to JAVA and unsure on what exactly is going into the jar and what not.
Is it important with which jre version you build the java class ? ( Xi is running on 1.4.2_12 ) I tried first with 1.5.0_06 and then with 1.4.2_9 and then 1.4.2_13 all with the same result.
I do this by adding a different jre to the properties of my project. And then I export to the .jar file . Is that enough ? ( I was expecting something like a 'build' option somewhere but I can't find that in eclipse )
When I imported the archive in XI, I also see a .Classpath , a .project , SAP_AG_G.RSA and a SAP_AG__G.SF file.
This reminds me of those ugly .dll incompatibilities which I had hoped not occurring with JAVA...:(
Any ideas ?
PS We are on XI 7.0 SP8 ( so the older note 755302 is not relevant )

Hi all,
I did understand that I had something todo with different versions ( as I started to make a first attempt with version jre 1.5 and then with other versions )
But somehow I apparently couldn't get my .jar file to be compiled to a 1.4.2_xx
( although I tried numerous settings in the Eclipse build path etc...)
Finally, I removed the 1.5 version and started from scratch using jre 1.4.2_10.
And now it works OK !
I'm sure you can configure Eclipse correctly to generate 1.4 compatible jar files ( even when running itself on 1.5 or above ) but I must have missed the right combination of settings ( as I said I'm new in Java / Eclipse....)

Dirk

Java Mapping - Class versions are incompatible (linkage error)

Thanks Raj.
But this note says

and I am already on PI 7.0.
Please tell me still I need to apply this?

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.
Regards,
Manish Agarwal.

Hallo Agarwal,
have a look in OSS Message #755302

Java Map

Hello,
I m using this JAVA MAp

import java.util.Map;
import java.io.*;

 //Declare the XML tag for your XML message
 String StartXMLTag = "<Payload>";
 String EndXMLTag = "</Payload>";
 AbstractTrace trace;
 private Map param = null;
 public void setParameter(Map param) {
 this.param = param;
 public void execute(InputStream in, OutputStream out) {
 trace =
 (AbstractTrace) param.get(
 StreamTransformationConstants.MAPPING_TRACE);
 trace.addInfo("Process Started");
 try {
 StringBuffer strbuffer = new StringBuffer();
 byte[] b = new byte[4096];
 for (int n;(n = in.read(b)) != -1;) {

 trace.addInfo("Process Completed");;
 } catch (Exception e) {
 trace.addInfo("Process Terminated: Error in writing out payload");;
Now when I m sending the file I m geeting the error
MAPPING">LINKAGE_ERROR
Incompatible class versions (linkage error)
I have compile this map using JDK1.6 and 1.4 both

Hi,
I usually compile like this:
javac -cp <path from PI library> -source 1.4 -target 1.4 <file.java>
Are you doing something like this?
Best Regard,

Lucene Highlighter linkage Error

Hello!
I am working with Tomcat. I have put the Lucene highlighter.jar in the folder lib. And I have created an extra css, where I say that the background color has to be yellow. The searchword has to be highlighted know.
I have got a dataTable in which the result of the following Lucene method is loaded:
public void search(String q, File index, String [] fields, ArrayList subresult, int numresults) throws Exception {
 Directory fsDir = FSDirectory.getDirectory(index, false);
 IndexSearcher is = new IndexSearcher(fsDir);

 IndexReader reader=null;
 query=query.rewrite(reader);
 QueryScorer scorer = new QueryScorer(query);
 SimpleHTMLFormatter formatter= new SimpleHTMLFormatter("","");
 Highlighter high = new Highlighter(formatter,scorer);
 high.setTextFragmenter(fragmenter);

 else if (0.6f <= f && f<0.7f){rating = "***";}
 else if (0.5f <= f && f<0.6f){rating = "**";}
 else if (f <= 0.5f){rating = "*";}
 Document doc = hits.doc(i);
 String abstracts =doc.get("ABSTRACTS");
 String title = doc.get("TITLE");
 TokenStream abstract_stream = analyzer.tokenStream(q, new StringReader(abstracts));
 TokenStream title_straem = analyzer.tokenStream(q, new StringReader(title));
 String fragment_abstract = high.getBestFragments(abstract_stream,abstracts, 5, "...");
 String fragment_title = high.getBestFragments(title_straem,title, 5, "...");

 }else{

But I get the following error.

 org.ajax4jsf.framework.ajax.xmlfilter.BaseFilter.doFilter(BaseFilter.java:220)
Does someone know what I am doing wrong?

Thank you guyz for your replies...Let me try to explain this a bit further.
Initially I got this error while testing a graphical mapping which was a straight forward ,source structure to JDBC UPDATE_INSERT structure without any functions or UDFs.
Then to check whether its my mapping problem I created some simple two field mappings as well , but all has the same problem now.While testing the mapping using the test tab you get the 'Class "com.sap.xi.tf._ <message mapping name> not found'
It gives a linkage_error while running the interface (runtime)
We tried restarting the Java Stack but with no luck

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 "Linkage error occurred when loading class MyClass" error.... why i am getting this error
Thanks & Regards
Ravi Shankar B

Here 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".
