Java mapping of application triggered an exception

Hi,
We have ascenario where a vendor will be sending us a cXML file which has the second line as <!DOCTYPE cXML SYSTEM "http://xml.cxml.org/schemas/cXML/1.2.009/InvoiceDetail.dtd">. If I open it in XMLSpy, it is saying the file as invalid. XI is unable to map this file. So we decided to remove that line using Java mapping and then do the regular graphical mapping.
I took the java code from the SAP note 812966 and used the aii_map_api.jar, dom.jar, jaxp-api.jar to create the class of that java file and used that class file by importing that into XI as a jar file.
I'm getting this error in the request message mapping of SXMB_MONI
<SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="">

<SAP:AdditionalText />
<SAP:ApplicationFaultMessage namespace="" />
<SAP:Stack>Java mapping of application triggered an exception</SAP:Stack>
<SAP:Retry>M</SAP:Retry>
</SAP:Error>
I'm new to this java mapping, Can you please provide me some details about what files need to be loaded into the XI along with the class file.
Appreciate you help.
Thanks,
MT.

Hi Prateek,
Thanks for your quick reply. Yes I have downloaded the aii_map_api.jar from <SAP_install_dir>/<system_name>/<instance_name>/j2ee/cluster/server<number>/apps/sap.com/com.sap.xi.services/
And also I have compiled my java code using the dom.jar, sax.jar, jaxp-api.jar and aii_map_api.jar.
I took the class file of my javacode and all the class files of the above mentioned jar files and prepared one single jar file, which I imported into XI.
It is not allowing me to make a single jar of the actual class file and all the supporting jar files.
What is the actual method of doing it.
Appreciate all your help. Thanks very much.
Thanks,
Maulik.

JAVA Mapping with SAX: Illegal character exception &

Hi everybody,
I use a SAX JAVA Mapping. It throws an error cause the xml that is parsed has a

like in
<D_3036>Company & Co. KG</D_3036>
Does anybody know how to solve the problem?
I do not want to replace the

Are there special settings/properties for the handler/parser?
Thanks

Hi all,
thanks for your comments and suggestions. The error was not cause by the problem I describes.
FYI:
If there is an ampersand in the middle of a string, than the standard method
characters
in the handler is called three times!
This let me asume the ampersand was the error.

Thanks!!

As already suggested, you can display custom messages using AbstractTrace.
trace = (AbstractTrace)param.get( StreamTransformationConstants.MAPPING_TRACE );
trace.addInfo("G1-CYCLE is missing");
For more on coding front refer:
http://help.sap.com/javadocs/NW04/current/pi/com/sap/aii/mapping/api/StreamTransformation.html
To get this trace seen in MONI, set parameter TRACE_LEVEL in SXMB_ADM to 2.

XI AF API call failed. Module exception: Java Mapping

Hi Experts,
I have faced a typical error for one of my interface. The Scenario is SOAP to SOAP and we are performing SOAP Lookup before sending the data to Target web service. We are using one Java Mapping 'FileIns_lookupLoad.java --- com/fi/' and performing the SOAP Lookup from within the code. In the Lookup Communication channel we are using 'Axis' as message protocol and passing couple of values through Module Key parameters. We have same ESR and ID objects in Development, Quality and Production (as per Version ID and History).
Now the problem is Lookup is failing only in Development but Quality and Production is working fine. I have replaced Quality CC URL with the development WSDL URL, but that worked fine. That means Development Web Service is good. We are getting the below error in Dev:
<SAP:Stack>StreamTransformationException triggered by application mapping program com/fi/FileIns_lookupLoad; Look Up Failed</SAP:Stack>

I have already checked with Basis and as per them JDK and Java versions are identical in Dev, QAS and Prod. It seems something is wrong with 'XI AF API' which we are calling from the channel. If we totally ignore Lookup process and send direct data, it is working fine. Target CC is also using Axis.
Sequence in CC: afreq ->xireq ->wssec2 ->xires ->afres
For any more information please let me know.
Thanks,
Nabendu.

Null exception in Java mapping

Hi Experts,
I am getting "Exception in thread "main" java.lang.NoClassDefFoundError: com/sap/aii/utilxi/misc/api/BaseRuntimeException
in line Container container = new Context(new FunctionWrapper(0)); " when trying to execute the java mapping inside my interface mapping.
I am using the following code iside my java class in NWDS when I get the above error:
//Get the message Header
          Container container = new Context(new FunctionWrapper(0));
          map = container.getTransformationParameters();
          strMessageID = (String) map.get("MessageId"); // Get Message GUID
          strMessageID = strMessageID.trim();
          strMessageDate = (String) map.get("TimeSent");
          strMessageTime = (String) map.get("TimeSent"); // Get Time Sent
I have also imported aii_mt_rt.jar, aii_map_api.jar, aii_utilxi_misc.jar into my class.
Please can you help me solve this problem.
Thanks and regards,
Brendon

I solved the problem by using
strMessageID = (String)param.get(
StreamTransformationConstants.MESSAGE_ID);

Exception while perfroming Java mapping in XI

Hi there,
Im doing some java mapping in XI using the standard/classic DOM and JAXP packages, I have tested everything outside XI and the code seems to be OK.
However when I deploy the code into XI self and run a test, something goes wrong.
This is the exception Im getting from my log (PS: In th eyes of XI eveything goes fine, but this is because I have all my code surrounded by try/catch statements...):
java.lang.ClassCastException: com.inqmy.lib.xml.dom.DocumentImpl
1) First, what I dont understand here is the fact that Im not doing any kind of parsing to this type "com.inqmy.lib.xml.dom.DocumentImpl" in my code, so Why XI is doing this?
2) It seems to me like XI internally uses this "fancy" INQMY package to perform my XML parsing/mapping. But nowhere in the documentation is mentioned, at least I haven't read about it.
3) Is there anyplace where I can find/download this package "com.inqmy.lib.xml.dom.*" so that I can test/debug my code using this specific SAP pacakge?
Can anyone give me some clues how to solve and prevent this issue? Below is the part of the code where the exception is generated:
 private void processMultiMessages(Vector indexVector, NodeList msgList) {
 Iterator iter = indexVector.iterator();
 Integer tempIndex = null;

Hi there,
I have included the inqmyxml.jar in my classpath and perfor
med some tests (outside XI), with good results.
However, when I copy/deploy the same classes into XI then the problem still there. My Java class is complaining about some ClassCastException, the error looks like this:
java.lang.ClassCastException: com.inqmy.lib.xml.dom.DocumentImpl
has anyone any ideas/clues was happening here?
Cheers,
Rob.
PS: These are the packages Im importing in my class:
import com.sap.aii.mapping.api.*;
import java.io.*;
import java.sql.Timestamp;
import java.text.SimpleDateFormat;
import java.util.*;
import javax.xml.parsers.*;
import javax.xml.transform.*;
import javax.xml.transform.dom.*;
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.stream.StreamResult;
import org.xml.sax.*;
import org.xml.sax.helpers.*;
import org.w3c.dom.*;
import org.w3c.dom.ranges.*;
import com.inqmy.lib.jaxp.*;
import com.inqmy.lib.xml.*;
import com.inqmy.lib.xml.parser.*;
import com.inqmy.lib.xml.dom.*;
And these are the Global vars Im using:
 // declare Global vars
 private Map systemParams;
 private InputStream in;
 private OutputStream out;
 private DocumentBuilderFactory domFactory;
 private DocumentBuilder documentBuilder;
 private Document mainDocument;
 private String path;
 private String separator;
 private File folder;
And finally this is the way I start my mapping/parsing process:
 ClassLoader cl = Thread.currentThread().getContextClassLoader();
 Thread.currentThread().setContextClassLoader(this.getClass().getClassLoader());
domFactory = DocumentBuilderFactoryImpl.newInstance();
 Thread.currentThread().setContextClassLoader(cl);
// Optional: set various configuration options
 domFactory.setIgnoringComments(true);
 domFactory.setIgnoringElementContentWhitespace(true);
domFactory.setValidating(false);
domFactory.setCoalescing(false);
// Create and set documentBuilder
documentBuilder = domFactory.newDocumentBuilder();
// parse the input file
mainDocument = documentBuilder.parse(in);

Throw exception in Java mapping and handle this in BPM

Hi,
I'll use a Java mapping in a BPM transform step. Is it possible to throw an exception inside this Java mapping and handle this in a BPM exception handler?
thanks and regards
Verena

Hi Verena,
In a BPM transformation step, I think you can throw exceptions only for system errors.
Let me explain with an example, one of the ways to handle your scenario:
Lets assume your Java Mapping fails then you can trap that exception in your Java mapping and compose an XML message which indicates that an error has occurred.
say for e.g.
<intermediateStructure>
<SatusDocument>
<StatusCode>ERROR</StatusCode>
<ErrCode>123</ErrCode>
<ErrDesc><!populate the thrown exception details></ErrDesc>
</StatusDocument>
<Payload>
<!contains actual XML message with data>
</Payload>
</intermediateStructure>
if Java mapping is Successful, you can compose the XML message as follows:
<intermediateStructure>
<SatusDocument>
<StatusCode>SUCCESS</StatusCode>
<ErrCode>0</ErrCode>
<ErrDesc></ErrDesc>
</StatusDocument>
<Payload>
<!contains actual XML message with data>
</Payload>
</intermediateStructure>
You can use BPM switch operation to switch to different processing branches say for e.g. "error" branch or "success" branch by examining the value of <StatusCode> tag.
Hope it helps !

Handling Java Mapping Exception in BPM Transformation step

Dear SDN members,
I have developed a File to File scenario using BPM as follows.
Step 1:
Sender file adapter picks the file from FTP server and using file content conversion mapped to XML structure.
Step 2:
BPM will recieve the XML payload , immediately in the block a transformation step is called with an interface mapping. In the interface mapping a Java mapping will be executed with certain data validations on the XML payload. If found any invalid data is there a suitable excptions will be raised . Here the transformation step should be catch the error and control should be sent to exception block to place the recived file as a error file.
else if the transformation is executed with out any issues, the file will be placed in success folder.
But in the transformation step, though java mapping thorwing exceptions, the control not going into exception block, instead it is continuing to next step i.e the file is placing in the success folder.
Can anybody tell me, how to handle the exceptions raised in java mapping in the BPM transformation step?
I have refered all the SDN blogs, forums related to this issue, but could not able to find the answer. Please help me?
Thanks & Regards
Vijayanand Poreddy

Hi Abhishek,
Once the file is picked from FTP server then sent to BPM,
the BPM steps
Step1:
-->Recive
Step 2:
Block Starts
 ---Block Start: New Transaction
 ---Block End : New Transaction
 ---Exception : Error
Step 3
Inside the Block
Transformation Step
 --Interface Mapping: <IM Name>
 -- Check box ticked for Create New Transcation
 -- Exceptions
 --System Error: Error
 --Source Message: Message recieved in Recieve Step (Step 1)
Step 4:
--Send
--Source Maessage: Output message from the Transformation Step
Block End
Inserted a Exception Branch for Block
Steps inside Exception Branch
-Control
 --Throw Alert
 --Alert Name
In the above scenario
The transformation step is not throwing error even my interface mapping going to error. The same transformation step if i place outside the block next to recieve step, then the transformation step is throwing error and BPM stops the process.
Also, when transformation is inside the block, i have used the exception handling on the send step inside the block. here it is throwing error as the source message payload is empty. because in the preceding transformation step the interface mapping is failed due to which there the target will not be filled. But even though it is not entered into exception block.

Call method execute of the application Java mapping

Hi,
I'm using a RFC Lookup in a Java Mapping. In PI 7.0 it was working fine. Now we use the Mapping in our PI 7.30 Testsystem and I get following LookupException:
Error when calling an adapter by using the communication channel CC_Receiver_RFC_XXXXX (Party: , Service: BS_ERP_XXX_400, Object ID: 445eef339f2039b0856093c54c3656dd) The channel with object ID 445eef339f2039b0856093c54c3656dd could not be found in the Integration Server Java Cache. Check if the channel exists in the Integration Builder Directory and execute a refresh of the Java Cache
The Channel name and Business Service Name are correct. If I look in the Integration Builder, my Communication Channel is working fine.
I did a complete restart, the error afterwards was all the same. How can I refresh the cache for the ID's?.
I checked the party name it's having the space value not with *.
Thanks

Hello,
Error when calling an adapter by using the communication channel CC_Receiver_RFC_XXXXX (Party: , Service: BS_ERP_XXX_400, Object ID: 445eef339f2039b0856093c54c3656dd) The channel with object ID 445eef339f2039b0856093c54c3656dd could not be found in the Integration Server Java Cache. Check if the channel exists in the Integration Builder Directory and execute a refresh of the Java Cache
This error usually happens when you have created the RFC Receiver that has an entry of * in the Party. What you can do is to recreate the CC and remove the entry in the party. Save and activate.
Hope this helps,
Mark

These three xml are the same:
<?xml version="1.0"?><a:xml xmlns:a="urn:123">root</a:xml>
<?xml version="1.0"?><xml xmlns="urn:123">root</xml>
<?xml version="1.0"?><ns0:xml xmlns:ns0="urn:123">root</ns0:xml>
But your code will work only with last one, because it doesn't bound namespace to prefix ns0.

Keystore access in Java Mapping Program - user J2EE_GUEST

Dear Gurus,
I have the following problem:
I need to validate the digital signature of a XML document and I'm using some examples provided by SAP as follows:
 InitialContext ctx = ctx = new InitialContext();
 Object o = (Object) ctx.lookup("keystore");
 KeystoreManager manager = (KeystoreManager) o;
 KeyStore ks = manager.getKeystore("Serasa");
{/code}
But I get the error below, saying that user J2EE_GUEST is not authorized. How do I change the user who executes java mapping, because I granted permissions in Visual Admin to another user.

Thank you very much

Hi Fabio,
first of all have you checked if standard functions to verify digital signature for pi adpaters would work for you?
We have used the following code to access the Keystore in a custom adapter. It accesses the keystore with the access rights of a JEE application (it has a reference to the sample adapter "sap.com/com.sap.aii.adapter.sample.ra"). Check out if it works in your mapping, too.
