Multiple header variables in bpelx:inputHeaderVariable

While investigating the use of the bpelx:inputHeaderVariable call for creating a SOAP message header, I found the following blog entry:
http://chintanblog.blogspot.com/2007/12/insertextract-soap-headers-in-bpel-it.html
The author creates three variables for passing security credentials in a SOAP message header, then invokes the partner link to the "secure" process using this Invoke activity:
<invoke name="Invoke_ExtractHeaderProcess" partnerLink="ExtractHeaderBPELProject" portType="ns2:ExtractHeaderBPELProject" operation="process"
inputVariable="Invoke_ExtractHeaderProcess_process_InputVariable" outputVariable="Invoke_ExtractHeaderProcess_process_OutputVariable"
bpelx:inputHeaderVariable="Variable_Username, Variable_Password, Variable_ComplexCredentialElement"/>
I downloaded his code to JDeveloper 10.1.3.3.0 and SOA Suite 10.1.3.1 and attempted to deploy it. I received the following error:
BUILD FAILED
C:\jdevstudio101330\jdev\mywork\InsertExtractHeaders\InsertHeaderVariables\build.xml:79: A problem occured while connecting to server "localhost" using port "8888": bpel_InsertHeaderVariables_1.0.jar failed to deploy. Exception message is: ORABPEL-05215

I had already attempted something similar in one of my own BPEL processes with the same erroneous result. The source of the problem would appear to be the list of multiple header variables since it disappears if a single variable is specified. Yet the author claims success with this technique.
How can I get this to work?
Thanks for your time,
Paul Camann

I see from Metalink that this topic was the subject of Bug 5623319, but it is difficult to tell from the trail of bread crumbs in the bug description whether (a) the bug was fixed, and if so, (b) the fix is included in JDev 10.1.3.3.0 or is a separate patch that must be applied. Clarification would be GREATLY appreciated.

How to pass header Variables along with body

Hi,
Here I am invoking siebel web service which is wsdl(SOAP) based web service. I tested it through sopaUI and it is working fine for me as I am getting proper response. here is the input payload structure.
Note: it is running on HTTPS, so SSL has been applied to this site.
it is loading as http not https. For every operation when we make a request, we are changing the link to https and submitting it. Then it is working for us.
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns="http://www.xxxxxx.com/2005/">
   <soapenv:Header>
      <ns:AuthorizationToken>
         <ns:Token>userName;Password</ns:Token>
      </ns:AuthorizationToken>
   </soapenv:Header>
   <soapenv:Body>
      <ns:WEBIndividualGet>
         <ns:key>{6D803C43-3917-4C99-91F3-003EB9E16E1F}</ns:key>
      </ns:WEBIndividualGet>
   </soapenv:Body>
</soapenv:Envelope>
Now I created the bpel projects like this.
Step 1:- in the xsd, I created two elements types
<xsd:element name="UsernameToken" type="xsd:string"/>
    <xsd:element name="PasswordText" type="xsd:string"/>
Step 2:- Then I created the WSDL in respect to above elements

<wsdl:message name="WEBAutTokenOut">
<wsdl:part name="userName" element="netObj:UsernameToken"/>
<wsdl:part name="passWord" element="netObj:PasswordText"/>
</wsdl:message>
<wsdl:portType name="portTypeName">
<wsdl:operation name="operationName">
<soap:operation soapAction="sopaAction">
</soap:operation>
   <wsdl:input message="netSer:SvcRequestMessage">
    <soap:header message="netSer:WEBGetAutToken" part="userName" use="literal"/>
    <soap:header message="netSer:WEBGetAutToken" part="passWord" use="literal"/>
   </wsdl:input>
   <wsdl:output message="netSer:SvcResponseMessage">
    <soap:header message="netSer:WEBAutTokenOut" part="userName" use="literal"/>
    <soap:header message="netSer:WEBAutTokenOut" part="passWord" use="literal"/>
   </wsdl:output>
</wsdl:operation>
</wsdl:portType>
Step 3:- and My Bpel looks like

<variable name="customHeaderVar" messageType="netSer:WEBGetAutToken"/>
    <variable name="customOutputHeaderVar" messageType="netSer:WEBAutTokenOut"/>
<sequence name="main">
<receive name="receiveInput" partnerLink="xxxxxxx"
             portType="netSer:xxxxxxxxxxx" operation="xxxxxx"
             variable="inputVariable" createInstance="yes"
            bpelx:headerVariable="customHeaderVar"/>
<assign name="AssignHeaderVariables">
      <copy>
        <from expression='"username"'/>
        <to variable="customHeaderVar" part="userName"
            query="/ns2:UsernameToken"/>
      </copy>
      <copy>
        <from expression='"soa1234"'/>
        <to variable="customHeaderVar" part="passWord"
            query="/ns2:PasswordText"/>
      </copy>
    </assign>
<invoke name="Invoke" inputVariable="xxxxxxxxxxxxxxxx"
            outputVariable="Invoke_OutputVar"
            partnerLink="xxxxxxxxxxx" portType="ns1:XMLSoap"
            operation="WEBGet" bpelx:invokeAsDetail="no"
           bpelx:inputHeaderVariable="customHeaderVar">
            bpelx:outputHeaderVariables="customOutputHeaderVar"/>
Note: When I am hitting siebel web service it is giving some out put, The output it self has header variable. so that is reason am added outputHeaderVariables.
< Here we have Transformation Activity >
<reply name="replyOutput" partnerLink="xxxxxx"
           portType="netSer:xxxxxxx" operation="WEBGet"
           variable="outputVariable"
           bpelx:inputHeaderVariable="customOutputHeaderVar"/>
That's about my project. But when test this service Am getting error. below is the error details.

BPEL Invoke: Input Header Variable

Is there a simple way to replicate the Input Header Variable that is part of JDeveloper 10g for BPEL Invoke activity?
Doing some work with 11g TP3 to work with salesforce.com and need to include a Session ID in the header of the massage sent to invoke a salesforce web service.
I made the change by manually pasting 'bpelx:inputHeaderVariable="headerRequest"' into the BPEL XML source document for the Invoke activity.
I'd also be interested in a way to more easily set the EndpointReference of the Partner Link than first importing ws-addressing.xsd schema document into the BPEL Project in order to next create an EndpointReference Element type variable, then copying an XML Fragment to the EndpointReference variable before finally setting the Web Service URL at runtime?
Thanks,
Mark

I started with the example code included with SOA Suite 10g.
All of the steps from that example, except the Input Header Variable, could be done the same way in both 10g & 11g.
To make things work, I had to manually paste the code noted in my initial post to BPEL XML source document.
I'm hoping TP4 or other future release will have the ability to include the header variable in the visual design tool.
I'm also hoping TP4, which I haven't used yet, or future release of the BPEL desginer in JDev 11g will come up with a simpler way to dynamically set the address of a partner link invoke.

File-adapter with Dynamic Directory/Filenames in Header-variables

Hi,
I have looked through the file-adapter documentation. And it says that you can use wildcards/regexpressions/dynamic file and directory names using the file-adapter-wizard. Also you can use the header-variables to specify the file and directory names at run-time.
Is it also possible to use the dynamic names using the header-variables?
I want to create a process that I can give in the file/directory-names at run-time and that it will look for a file using the wild-cards to pickup. Since at run-time I often do not know the name of the file, since it might contain a sequence or date/time-stamp. But I do know the location and the structure of the file name (that is specified at config-time).
The same question for outbound: if I specify a name in the header-variables with forexample '%seq%' in the name, like 'filename_%seq%.XML', will it then create the file with the sequence?
Thanks in advance.
Regards,
Martien

Hi,
I've been trhough this document over and over again, but did not find anything on how to do it actually. But I found out that the file-outbound-header wsdl does not contain a directory element after generation by the wizard. But you can add it afterwards.
Also you can replace the location attribute in the jca:address element of the adapter-wsdl by mcf properties (host, username, password) and override them by copying the values to the partnerlink using bpelx:properties.
I planned to put the details in my blog.
Regards,
Martien

Input Header Variable

Hi all,
can some one please provide me help as to how do we declare input header variables in my BPEL process using the BPEL editor.I want to add it to make WS-Addressing headers visible to my web services container.I explored the editor but I am not able to find how do we add the header variable which belong to bpelx namespace.
Do I need to manually edit my source code to make it visible or is there some other way to achieve it??Are there any samples avaiable for it??
Please help....

How to include wildcard in FTP adapter header variable?

I have two partner links that use FTP adapters. The first one puts a file on the FTP server. It specifies a dynamic outbound file name based upon an input variable and the timestamp in the format "test_BATCHID_yyyyMMddHHmmss.csv" (e.g. test_1011_20050925153059.csv). This part works as expected.
The second partner link is supposed to pick up a file on the same FTP server. This inbound filename will be based upon the outbound filename and another timestamp in a format such as "originalfilename.yyyyMMddHHmmss.txt" (e.g. test_1011_20050925153059.csv.20050926091541.txt). I have created a Transform action with a mapping to convert the outbound filename and assign it to the inbound header variable. It concatenates the outbound filename and ".*.txt" within the mapping. The inbound header shows up as test_1011_20050925153059.csv.*.txt in the audit, but the process hangs at the receive activity and the file never gets retrieved. Perhaps the asterisk is being interpreted literally?
Does anyone know how to specify a wildcard character in an xpath expression in a way that it will be interpreted as a true wildcard? Or is there another way to tell the inbound adapter to look for a dynamic filename using wildcards?

BPEL patch 1 supports performing a synchronous read using a BPEL invoke activity. The following forum post shows how to configure a read adapter manually.
Re: Help! Three questions about FileAdapater.
The subsequent patches of JDeveloper allow such an apdater to be configured automatically.
ps: This adapter can be used to read a single file only i.e. you cannot use a wild character.

SSO to a weblogic application via a header variable, possible?

Hi
Is it possible to provide single sign on to a weblogic application via a header variable?
We would like to follow a similar model to what's used with OC4J at:
http://download.oracle.com/docs/cd/E10761_01/doc/oam.1014/e10356/osso.htm#BJFJBCHB
Any feedback is appreciated.

Yes this is possible via a custom Identity Assertion Provider if you are using Weblogic security. You can write the J2EE provider to extract the header and map the user to a LDAP user when you configure the authentication provider to use the same user store as OAM.

SSO to other apps via HTTP header variable

We are on NW EP6.0 SP16. We need to add the "user id" as http header variable so that other apps which are non SAP can access our header variable and log on with that user id. Is this available by default? Or we want to achieve this how best we can achieve this.
We can use the code to get the user id and add it to header variable. If we use this route which is the jsp page we need to add the code?
Thanks

Hi,
we can you login modules provided by SAP to accomplish this.. you can use header variable authentication login module to acheive your requirement.
please refer: http://help.sap.com/saphelp_nw04/helpdata/en/8f/ae29411ab3db2be10000000a1550b0/frameset.htm

Multiple value variable - not showing Multiple values in the report

Hi,
I have careated a Multiple value variable for one of the characteristics in my Query. however, When i run the Query and select multiple values for the same, the report displays values for only the first selection.
Could you help me resolve this ?
Rgds
Shweta

Hello Shweta,
Are you running the report in the Analyzer excel or Web?
May be you can check the following:
1. Use the latest FEP. It is working for me.
2. May be the other values that you selected do not have corresponding keyfigures values. Hence it is showing only the first one.
Try selecting other values ( except first one selected this time )

Error in setting up HTTP Header Variable Authentication

Hi,
I am trying to set-up SSO for SAP Biller Direct aplication (deployed on SAP J2EE 7.0) using HTTP Header variable authentication.
As per SAP documentation I have created a new login module "HeaderVariableLoginModule" pointing to class "com.sap.security.core.server.jaas.HeaderVariableLoginModule".
Then I have added this new login module to Statck "Ticket" and the new config looks as below. HTTP header when UID is passed is USI_LOP.
Name                                                                                Flag                                            Options

                                                                                Header=USI_LOP
BasicPasswordLoginModule                                                           Optional
CreateTicketLoginModule                                                                 Optional                                         ume.configuration.active= tue
EvaluateTicketLoginModule                                                              Sufficient                                      ume.configuration.active= tue
The problem I am now having is that the authentication through HTTP_HEADEr does not work. Even though I ahve increased the trace level for JAAS module to debug, there is not any type of information generated in the log.
Each time I call the Biller Direct URL from the extrenal web server which also passes the HEADER variable for Authntication, the authrisation just fails and I am being shown a Logon Screen to pust UID/PASSWORD.
Can someone please guide me, how I can debug this? There is very no information whether anyone tried to login with HEADER varibale and that has failed...
Also, I am not pretty sure whether I am using the right Authentication Stack, which is is Ticket in my case..
But when I enter the application without any URL redirects and enter UID and password directly for Biller Direct, I get the following in log file, which makes me believe that I am using the right stack.
LOGIN.OK
User: CONDLG
Authentication Stack: ticket
Login Module                                                               Flag        Initialize Login      Commit     Abort      Details

Any help will be very much apprecated..
Thanks,
Vikrant Sud

Vikrant,
The reason why it is not working is because your login modules in ticket stack are in wrong order and with wrong flags. The first one should be EvaluateTicketLoginModule with flag=SUFFICIENT, then the Header Variable login module, with flag=OPTIONAL, then CreateTicketLoginModule with flag=SUFFICIENT, then BasicPasswordLoginModule with flag=REQUISITE, and lastly CreateTicektLoginModule with flag=OPTIONAL
Thanks,

Multiple Header line in Receiver File adapter

Hi,
I have an issue in Receiver File adapter with multiple header lines. I am able to get only 1 header lines in the receiver file but not multiple header lines with 'nl' since it is static in file mode
[CommunityTag:Header]
empNo,EmpName,Age
[CommunityTag]
I tried with the below in content conversion one as below with no luck
Root.addHeaderLine=1
Root.headerLine=[CommunityTag:Header] 'nl' empNo,EmpName,Age 'nl' [CommunityTag]
Root.fiedSeparator=,
Root.endSeparator='nl'
I am getting the Header line as same row as static text.
Can you advise this.

Hi Gabriel, I suggest to produce the header lines from additional nodes in the message payload. That means you need to modify the data type of the target message in order to generate an extra structure in the payload. Use constants in message mapping to generate the header column names, e.g.
<Header>
<H1>CommunityTag:Header</H1>
<H2>empNo,EmpName,Age</H2>
<H3>CommunityTag</H3>
</Header>
In content conversion you have to convert the Header row with
Header.endSeparator='nl'
You won't need parameter addHeaderLine anymore then.

Hi,
I had attempted to do it in the object oriented way, but found no ready solution, so I settled for the below solution.
Please use the function REUSE_ALV_COMMENTARY_WRITE.
This allows you to print multiple lines in the header.
I had a requirement of showing 5 lines in the header.
So i went on like:
DATA: it_list_commentary TYPE slis_t_listheader,
           wa_list_commentary TYPE slis_listheader.
wa_list_commentary-typ = 'H'.
wa_list_commentary-info = <text>.
APPEND wa_list_commentary TO it_list_commentary.
wa_list_commentary-typ = 'S'.
wa_list_commentary-info = <text>.
APPEND wa_list_commentary TO it_list_commentary.
I fed he internal table with all 5 lines like above.
Finally I called the function.
CALL FUNCTION 'REUSE_ALV_COMMENTARY_WRITE'
    EXPORTING
      it_list_commentary = it_list_commentary.
Regards,
Prosenjit.
