XI 3.0StringBuffer Error java - mapping

[Former Member]

Hi @ll;

I try to implement a java mapping in SAP Xi 3.0;

by trying to use the "append-method of the StringBuffer class.

But the following error arises:

<b>java.lang.NoSuchMethodError; java.lang.StringBuffer: method append(C)Ljava/lang/Appendable; not found.</b>

Can anybody help me?

thanks

I had same problem - StringBuffer seems to be not working under XI.

Finally I've found that I had wrong JRE at my specific project libraries. I've changed it from 1.6 to 1.4 and rebulid the source.

After uploading it to XI everytihng worked fine.

So, anyone - please check Your libriaries - that's the problem.

Hi Jochen,

I am using string buffer in advance user defined java function as follows and the append function works fine.

===============================================

String NTTEXT = "";

StringBuffer tmpStr = new StringBuffer();

for(int i=0;i<a.length;i++)

{

tmpStr.append(a<i>);

}

result.addValue(tmpStr.toString());

================================================

Post your code sample of the appending part. Lets have a look.

thanks,

Hello,

Does it work in your JDE (Eclipse) ?

Yes, it works in Eclipse!

I just compare JDK 1.3 and 1.4 and perhaps the method you want to use only exist in 1.4 no in 1.3.

You must change your JDK to 1.3 to developp XI mapping.

We used this method (append) also in Xi 2.0 and it works without any Problems.

so the method exists in JDK 1.3 and also in higher versions.

Hi @ll;

the code:

-

---

StringBuffer xmlFile = new StringBuffer();

int c = in.read();

while (c != -1) {

xmlFile.append((char) c);

c = in.read();

}

-

---

thanks

Jochen

Perhaps you have already tested it, but try to you an other method with an other parameter (try without using cast)

<u>For example :</u>

xmlFile.append(c);

<b>or</b>

xmlFile.append(Integer.toString(c));

Regards,

Chris

Hi @ll;

I edited the code.

I try to append just the string "Hello World" to the StringBuffer!

import java.io.DataOutputStream;

import java.io.InputStream;

import java.io.OutputStream;

import java.util.Map;

import com.sap.aii.mapping.api.StreamTransformation;

import com.sap.aii.mapping.api.StreamTransformationException;

public class TestMapping implements StreamTransformation {

String delemiter = new String(";");

/**

• @see com.sap.aii.mapping.api.StreamTransformation#setParameter(Map)

*/

public void setParameter(Map arg0) {

}

public void execute(InputStream in, OutputStream out) throws StreamTransformationException {

try {

StringBuffer resultXML = new StringBuffer();

resultXML.append("HelloWorld");

DataOutputStream writeOut = new DataOutputStream(out);

writeOut.writeBytes(resultXML.toString());

} catch (Exception e) {

e.printStackTrace();

throw new StreamTransformationException("Exception during KeyMapping: (" + e.getClass().getName() + ") " + e.getMessage(), e);

}

}

}

Finally the same error arises!

I just test your java mapping and it works for me.

What XI verson you use ?

Hy,

I am a colleague of Jochen...

we also have the XI3.0 SP11.

It doesent works at our developement and qualtity XI.

Maybe we have an installation problem (we are running the XI on ZSeries and DB2).

I think we will open an OSS for this problem.

Thank you for your help,

Thomas

We have an RHEL ES3 with SAP DB and jdk 1.3.1.

Good luck
