Set a variable in Adapter Module and read it during message mapping

Hi guys,
is there any way, how I could set some variable and store its value during the adapter module processing and read back this value in message mapping and use it? Without using a database or files.. I mean, some j2ee storage or something like that..
Thanks for your help,
Olian

Hi guys,
thanks for your answers.. just a clarification, what the problem is.
I need to validate a message in the adapter module, if it's digital signature is valid. If it is, I need to send back to the sender a return code (message) OK, otherwise ERROR. I can't modify the message (or dynamic configuration) as I'm using a WSS in the sender channel. The system doesn't allow me to change anything in the message, so I can't find out in the mapping what the validation result was. I then tried to do the validation directly in the message mapping, but I have some issues there with libraries or what, because the validation code, which works in the adapter module, doesn't work in the mapping java class. So my final thought was maybe I could validate the message in the adapter module and pass the result to the message mapping and then create an appropriate return message (in the mapping). However, I see no way of passing a value there. I'm stuck and have no Idea how to resolve the problem. Any hints guys?
Thanks a lot for your help!

I want to set a variable with default value and can be changed by the user

hi,
i want to set a variable with default value and can be changed by the user, so i new a variable with setting : customer exit, single value, optional, ready for input.
in my customer exit code, i set a default value, eg. 20070530
when the variable screen popup, it display the default value 20070530, i changed it to 20070529, but it doesn't work , it still display the data in 20070530, how can i solve this problem?
your help is appreciated.

Liu,
As mentioned by Anil, you need to restrict your customerr Exit code to I_STEP = 1.
or.
Open your Variable in change mode, in the Last Page os the Variable Maintenance you can provide default value. Note: you are doing same thing in Customer Exit. In your case no need of Customer Exit.

Regds : Adapter modules and custom modules

Based on which criteria, we will start working towards custom and adapter modules

Hi praveen,
There is no specific criteria on which the adapter modules have to be developed.The only criteria is the Business requirement.SAP ships the Ready to use adapter modules to enchance the functinalities of Available Adapters.
Ex: There is a Adapter module called ZIP bean that can ZIP the files that have been received on the target side .Simlilary there are about 9 SAP provided modules which can meet certain business requirement.
If u like to have ur own u can develop one and go ahead.So many Giudes are available in SDN for that.to get an idea.
Please refer the followig links .Hope this is useful

PI 7.1 Adapter Module Development - Identify SOAP Fault Message

Hi Experts,
here's a PI 7.1 Adapter Module Development issue I hope you can help me to resolve. It's about identifying SOAP fault messages.

Scenario at a glance:
Adapter Modules placed in the modules chain at request and response time in a synchronous Scenario:
- Request: SOAP Axis to RFC 
- Response and Fault Response: RFC to SOAP Axis

The issue is how to identify SOAP fault message in SOAP Axis Adapter Module in the response message:
The client gets SOAP fault messages like the follwong one:
 <SOAP:Body>
 <SOAP:Fault>
 <faultcode>SOAP:Server</faultcode>
 <faultstring>Server Error</faultstring>
 <detail>
 <ns1:exception xmlns:ns1="http://typen.geschaeftsstelle.pab.barmer.de">
 <ns1:errortext>bla bla bla ...</ns1:errortext>
 </ns1:exception>
 </detail>
 </SOAP:Fault>
 </SOAP:Body>


But when trying to access the tags faultcode and/or faultstring in the adapter module via xPath expressions I do not get them. Obviously the SOAP Fault tags are built AFTER the adapter module has been passed. So my question is:
How can I clearly/uniquely detect a SOAP fault response message (and distinguish it from a "normal" response message) in my SOAP Axis Adapter Module?

I tried it the following way:


// Check Message Payload for SOAP Fault Message via xPath expressions
...
// SOAP Fault Code
zv_xPression = zc_constXPattern.replaceFirst("&", "faultcode");
zv_soapFaultCode = XPathAPI.eval(zv_doc, (String) zv_xPression).toString();
// SOAP Fault String
zv_xPression = zc_constXPattern.replaceFirst("&", "faultstring");
zv_soapFaultString = XPathAPI.eval(zv_doc, (String) zv_xPression).toString();
// check for SOAP Fault Message
if (zv_soapFaultCode.equals("") && zv_soapFaultString.equals("")) {
 // Create Audit Log entry - NOT a SOAP Fault Message
 zv_msgText = zc_constModuleName + " 0190: xPath - OK! This message is NOT a SOAP Fault Message";
 zv_audit.addAuditLogEntry(zv_msgKey, AuditLogStatus.SUCCESS, zv_msgText);
 zv_faultCheck = false;
}
else {
 ...
 // Create Audit Log entry - SOAP Fault Message
 zv_msgText = zc_constModuleName 
 + " 0200: xPath - this message is a SOAP Fault Message. " 
 + " - Faultcode is: " + zv_soapFaultCode 
 + " - Faultstring is: " + zv_soapFaultString; 
 zv_audit.addAuditLogEntry(zv_msgKey, AuditLogStatus.ERROR, zv_msgText);
 ...
}
...

But zv_soapFaultCode and zv_soapFaultString are always empty (with other payload tags this coding works fine).

Any ideas? 
Thanx very much in advance!
Regards,
Volker

Hi Alex!
Like already mentioned I solved my problem by identifying the SOAP exception with the messageClass attribute of the PI message header. Acess code:
try {
String zv_msgClass = zv_piMsg.getMessageClass().toString();
} catch (Exception e) {
zv_msgText = zc_constModuleName
+ " E0110: Message processing terminated."
+ " Reason: Error while getting MessageClass "
+ zv_dataSource
+ e;
// create trace and audit log entry (severity ERROR) for exception
zv_location.errorT(ZV_SIGNATURE, zv_msgText);
zv_audit.addAuditLogEntry(zv_msgKey, AuditLogStatus.ERROR, zv_msgText);
ModuleException me = new ModuleException(e);
zv_location.throwing(ZV_SIGNATURE, me);
e.printStackTrace();
throw me;
} // end of try-catch-block
But I do not think this will solve your problem. I am almost sure, that something in your Axis configuration is wrong/missing. If a handler cannot be instatiated then it really may be missing. Have a look at defaultTrace.trc. Maybe you will find more suitable information about the root cause of your problem. Also have a look at NWA under software components and/or application modules if you can find/see your modules.
But there is a general issue when trying to catch PI fault messages. If e.g. the requestor tries to login with wrong userid/pasword, then you will have no chance to catch this kind of error - at least as far as I know. Because in this very early stage of PI message processing no module is called.
One last question: Did you develop your own Adapter or just an adapter module? In the first case: Is your adapter started and healthy? Have a look at RWB -> communication channel monitoring.

IMessage - how to show if someone received and read the sent message?

Hi,
I'm trying to figure out how to see when I sent a iMessage to someone if they have received it and "read" it. I know in settings there's an option that shows others when I have read their messages. Do they have to have this turned on in order for me to see this?

Yes, as far as I know, they do. I enabled the setting on my phone and my husband's because it's nice to see when he read my message. (I doubt he pays attention to that feature, but it's important to me.) I haven't used iOS with anyone else yet. Apparently none of my iPhone owning friends have updated to iOS 5 yet.

Function Module Undefined during message mapping.

Hi,
My Scenario is Idoc to Multiple Files without any condition i have to drop 2 files at the 2 differient directories of FTP,
So we are using PI 7.1 and in the Message Mapping using Signature Tab we have added 2 Target messages and at the source we have used the IDOC.
When we see the structure under Definition Tab in Message Mapping, We are facing the below error
"FUNCTION MODEL UNDEFINED"
So can anyone suggest what could be the problem, do i need to change any occurence in the signature tab for the message types else what shuld i do to get the structures in the Definiton Tab.
Please suggest how to approach this..
Thanks,
--Kishore

My Scenario is Idoc to Multiple Files without any condition i have to drop 2 files at the 2 differient directories of FTP,
1. Use multi mapping - /people/jin.shin/blog/2006/02/07/multi-mapping-without-bpm--yes-it146s-possible
2. use two different inbound interfaces, and do two different interface determination without conditions for the same receiver determination

File Adapter Writting and Reading strategy

Hi All,
When i am trying to write data to file, it was opened by another person and it gave error in the receiver communication channel saying like source is using by another application. Which is well and good
But in case of Sender channel while writing the data to file even thought it is opened by another person, Sender file adapter is picked the file.
I didn't get the reason why it is like this. Any one of u had the same issue???
Regards

Hi Neetesh,
>>hmm ... that's weird ... you mean to say that the polling frequency is now (20 + 100) = 120 secs ? Unless and until the file is not being modified or the file is not "open", this parameter shouldn't work ...
Examples
Poll interval is 20 sec and MSecs to wait is 100000( 1 MIN 40 Sec)
1) If file is there and did not opened / modifying
waiting till 1 min 40sec to pick the file
2) If the file is there and Modifying it
Adapter is waiting 1 min 40sec if the files have been changed.
3) If there is a file and just opened, not writing any files
Waiting for 1 min 40 sec to pick the file
>>Can you share the adapter log?

Siri and reading new text messages.

Why is Siri no longer responding "would you like to reply or read again" after reading back a new text message?

I never said there wasn't a change. What you expect and what Apple is planning or doing may not always be the same thing. Speculation is prohibited on these forums but, I'll repeat what I said before and hope you can figure it out: Apple has said there will be new features and improvements in Siri with iOS 7. Sometimes, features get removed for various reasons in beta products and are put back in the later releases.
And, since you've never beta tested a product for two years, you must not have used Gmail until rather recently.

PI 7.1 Adapter Module - meaning of VERSION_ID and serialVersionUID?

Hi!
I am currently developing my first PI Adapter Module. In SAP sample coding GetHostName I find the following declarations and I ask me what's the meaning and/or purpose of these declarations:
public static final String VERSION_ID = "$Id://tc/aii/30_REL/src/_adapters/_sample/java/user/module/GetHostName.java#1 $";
satic final long serialVersionUID = 7435850550539048631L;
And additionally how I have to declare these two variables for my adapter module ... This comes true especially for VERSION_ID, because serialVersionUID can be generated by NWDS using quick fix feature. It then declares such a variable ...
Thanxs for any hint in advance!
Regards,
Volker

Hi Pavel,
public - this is the visibility modifier (it means that the body method can be call by any outside method)
static - the method is a static instance of the class. Not sure what exactly it does though.
final indicates that the value of the variable won't change - in other words, a variable who's value can't be modified after it is declared.
Use public final static String when you want to create a String that belongs to the class (no instance necessary to use it), and that won't change, for instance when you want to define a Stringconstant that will be available to all instances of the class, and to other objects using the class, depending on the access modifier:
public final static String MY_CONSTANT = "SomeValue"; // ... in some other code, possibly in another object, use the constant: if (input.equals(MyClass.MY_CONSTANT)
All the variables are implicitly public static final in a Java Interface.
Is it a good coding practice to use public static final in constant variable although it is declared inside an Interface.
For example :
public interface TestInterface{ public static final String EX_CONSTANT = "ABC"; public static final int EX_INT_CONSTANT = 5; public static final double EX_DOUBLE = "5.0"; public static final Integer EX_INTEGER = 10; }

Adapter Modules: Set parameter values dynamic?

Hi everybody,
is it possible to set parameter values in adapter modules dynamic?
Thanks Regards
Mario

Hi all,
thanks for your replies.
My problem is not solved.
To make it clear,
I want to set an attachmentName in Mail receiver adapter WITHOUT using the MailPackage.
This is possible:
ModuleName:        localejbs/AF_Modules/MessageTransformBean
ModuleType:        LocalEnterpriseBean
ModuleKey:        CHAN
Parametername:        Transform.ContentDisposition
ParameterValue:        attachment; filename="NameOfAttachment.txt"
I want to set "NameOfAttachment.txt" dynamically. How can I achieve this? Thanks, regards

How to access Adapter Specific Message Attribute in my own adapter module

Hi,
I'm developing a mail adapter customer module. Now I have a requirement about getting the CC information from mail. Even if I
checked the option of "use mail package" when configing sender Mail Adapter, I still can not get CC information in my module
because it is not included in mail package.
I got to know CC information is included in ASMA(Adapter Specific Message Attribute), but how can I access ASMA in my module?
Till now I know there are two ways to access ASMA
1. use AF_Modules/DynamicConfigurationBean XI standard module to access ASMA.I did it as below:
add this module in front of my own module, then set key: write http://sap.com/xi/XI/System/Mail SHeaderCC and value :
message.refToMessageId(which message property should be put here?). I'm trying to get it by message.getRefToMessageId() in my
own module. But what happens is not as I expected, I get null instead of CC information. Which step I did wrong?
2. use mapping api
 DynamicConfiguration conf = (DynamicConfiguration) container
 .getTransformationParameters()
 .get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
 DynamicConfigurationKey key = DynamicConfigurationKey.create(
 http://sap.com/xi/XI/System/Mail,
 SHeaderCC);
but how can I get container object in my module?
Is there any other way to access ASMA in customer module?
Thanks

hi,
>>>>but how can I access ASMA in my module?
have a look at this blog:
