BPEL Variable Assign Problem

I had developed a Web Services with 2 methods:
1, return XML data in string datatype
2. return XML data in Element
Both are work fine in normal web services invocation. However, when I try to invoke them in BPEL, I got trouble on them.
For Method 1, I can succeed to call the web services and got the data back, but when I try to assign the XML to other variable (use the result xml xsd to create). It only assigned the whole XML data into the first element of XML such that I cannot further process the data by transformation.
For Method 2, the BPEL enginee failure on compile the project as the enginee reported cannot regonize the "xsd:any" datatype in the invoking web services.
any guys have idea about it? Thanks

Hi,
i had some problems too using xsd:any in the past.
Check out xsd:anyType.

BPEL variable access problem - ORABPEL-02118

Hi,
I have a method which accesses the variable of a BPEL process. It worked well with the Soa Suite 10.1.3.1, but I re-install the SOA Suite with the Advanced installation and applied the 10.1.3.3 patch and now I have this error message:
0 - ORABPEL-02118
Variant not found.
The variant "PatientRecordVariable" has not been declared in the current scope. All variants must be declared in the scope before being accessed.
Please check that the variant "PatientRecordVariable" is properly declared; otherwise there may be a misspelling in the name of the variant.

The problem is at the "getField" method. I was wondering if somebody encountered this error and know how to solve it. I think it should also be possible to access the variable directly from the database (I'm using XE) but I don't know in which table to look.
Any help would be greatly appreciated. Thanks.
Amir

When I display the debugTrace message for the process instance using
System.out.println(instanceHandle.getDebugTrace());

There is a variant element with the attribute key whose value is "_$$variable-name" and the element has the value "PatientRecordVariable". I don't know if this is related to my problem, but if it is, I still don't understant why it could not get the data of this variable.
Is there any way to get bpel processes' variable data from the database? I browsed the tables but I haven't found them. Hope somebody knows it.

Formula Node variable assignment problems

I have a formula node with the follwing:
Inputs:E,X,T,PD,I
OutputsK,PD
The statement inside the formula node is:
if (Eelse if (PD=1) if (E else if (E<=X) ;
else PK=I, PD=1;
The logic seems to be working the way I want, the problem is in the last else statement. PK is never assigned the value of I. however, PD is assigned the value of 1. There are no errors indicated.
The source of the I input is the iteration # of the For loop where this formula node is located.
Anyone see what I am missing??
Thanks,
Mike

Mike,
In comparisons, == should be used instead of =. This is a very common mistake, and a reason that forumla nodes should be avoided if possible (except of course for very long formulae that would require a lot of nodes.
It looks like your code would be better represented with LabVIEW nodes instead of in a formula node (for readability - there is no performance difference.)
Also, you may wish to reconsider using an Input variable that has the same name as an output variable. Try using PDi and PDo, or PD1 and PD2 instead.
Good luck.

Problem with asyn bpel process assign activity

hi
i m creating asyn bpel process,in my assign activity,i want to copy operation.But it seems that when i expand my input variable it doesnt expand.so i m not able to copy.what would be the reason.anybody suggest me
thanks

works for me
i added the xsd to my composite application
created a new bpel in it, for input/ouput used both your elements.
after that i added the assign and could just 'browse' the tree to both the input-element and the result-element, with this result :
    <sequence name="main">
        
        <receive name="receiveInput" partnerLink="bpelprocess2_client" portType="client:BPELProcess2" operation="process" variable="inputVariable" createInstance="yes"/>
        
        <assign name="my_assign">
            <copy>
                <from variable="inputVariable" part="payload"
                      query="/ns1:AsyncallerProcessRequest/ns1:input"/>
                <to variable="outputVariable" part="payload"
                    query="/ns1:AsyncallerProcessResponse/ns1:result"/>
            </copy>
        </assign>
        <invoke name="callbackClient" partnerLink="bpelprocess2_client" portType="client:BPELProcess2Callback" operation="processResponse" inputVariable="outputVariable"/>
    </sequence>when you put your bpel in design mode (first tab), and the and the left bottom browse to <your process.bpel> > Variables > Process > Variables > inputVariable > payload > ns1:AsyncallerProcessRequest > input
you do see this element ?
at the bottom fo this window you see a checkbox "show detailed node information", in case of errors or non validation xsd's this would be usefull, but the xsd validates for me.
any other errors you can find ?

Read XML in BPEL and assign values to variables

Hello,
I need to read an xml message in BPEL and assign variables created in BPEL the values of elements in XML message. Whats the best possible way to do this.

When you say"*read an xml message*", is the xml coming as input message or you need to read from file ?
If you want to read from file, you can make use of the below function.
Returns the string value of an element defined by lookupXPath in a XML file (docURL) given its parent XPath (parentXPath), the key XPath (keyXPath) and the value of the key (key). Usage: oraext:lookup-xml(docURL as string, parentXPath as string, keyXPath as string, lookupXPath as string, key as string)
Example: oraext:lookup-xml('file:/d:/country_data.xml', '/Countries/Country', 'Abbreviation', 'FullName', 'UK') returns the value of the element FullName child of /Countries/Country where Abbreviation = 'UK' in the file d:\country_data.xml
Thanks,
Vijay

How to set values to bpel variables from Java

I have a java class to create files and populate some contents into it. On success it returnes "File Created"
I used the following code to achieve it :-
WriteFiles objWriteFiles=new WriteFiles();
String para=((oracle.xml.parser.v2.XMLElement)getVariableData("inputVariable","payload","/client:FileTestProcessRequest/client:HO_ORG_ID")).getFirstChild().getNodeValue();
String result=objWriteFiles.writeHeaderInfo(para);
(writeHeaderInfo is a method in my java class)
addAuditTrailEntry(result);
I works fine..Now I want to assign this reult value to a bpel variable .. I tried doin it like below:-
setVariableData("outputVariable","payload","/client:FileTestProcessResponse/client:result" , result)
but its not working...I get a fault ...
Can anyone help me out...
Thanks,
Githa.R.S

In this example :

Accessing BPEL Variables in XSLT

Hi All,
In a BPEL PM process I need to be able to access a global BPEL process variable in the XSL transformation. When I use any functions in the "Transform" activity I do not see the BPEL variables in scope. Any idea on how can this can be done ?
Regards,
Venkatesh.

This causes a problem with the XSL Mapper. If I try to add an XPath-expression component to use this function I get the Warning message :-
"Function of name "bpws:getVariableData" not found."
If I continue, the following XSL segment is generated :-
<tns:comment>
<xsl:value-of select="bpws:getVariableData(?,?,?)"/>
</tns:comment>
This compiles ok, but when I run the business process, I get the following error from the transformation component :-
XPath expression failed to execute. Error while processing xpath expression, the expression is "ora:processXSLT("transformDimToRAN.xsl", bpws:getVariableData("invokeDimensionGateway_getFutOptTradesSelect_lastProcessedTradeRef_OutputVariable", "FutOptTradesCollection"))", the reason is Extension function http://schemas.xmlsoap.org/ws/2003/03/business-process/ : getVariableData is unknown. Please verify the xpath query.

Variable Assignment : Workbook broadcast

Hi gurus,
We have been broadcasting 31 Inventory workbooks on a weekly basis for the past couple of months. The workbook is based on 1 inventory query which has a Cal Month and Store Location as mandatory variables. Obviously, while broadcasting the same, we should be able to set these variables in the Variable Assignment of the Workbook Precalculation Tab.
Earlier I was able to see them in the variable assignment assignment for this workbook. We havn't changed the query, no changes in the system, No changes at all. But now I am not able to see a single variable in the variable assignment except for this variable that says Tech.Cont.: Time Frame for which Data is Selected.
I am not sure where can I see the variants for this workbook. Anyways, we havn't mentioned any variants in the workbook precalculation tab. Please help me with this issue.
I executed the query and tried broadcasting the corresponding query, Here I am able to see the variable assignment. But not for the corresponding workbook. Creating all the settings right from the scratch for changing from workbook broadcast to query result broadcast would be a very tedious task which I don't want to undertake right now.
Can anyone please help me with this problem.
Thanks & rgds,
Sree

Hi Murali,
Thanks for your answer and sorry wasn't able to respond early.
As I had mentioned, this problem didn't exist earlier. However, all of a sudden, we have started to face this issue. Global variants were never created because we are not using the option of VARIANTS, instead we use Variable Assignments. This has been the practice for the past many months, but all of sudden since last month, we started having this strange issue where we could'nt determine the variable assignment.
When know I click on the variable assignment create link, there is only one variable that appears in the screen "Tech.Cont.: Time Frame for which Data is Selected", I donot see any other variables. Earlier though, i was able to see all the other variables (Plant, division, etc).
Please let me know if you have any answer for this issue.
Thnks & rgds,
Sree

Variable Assignment-Workbook Precalculation

Hai Guys,
I have a problem while executing.please,go through it
Start---BEx Analyzer--
Create new work book.While executing the work book,it is asking me to enter variable values.Once the variables are given and when start executing it, i am getting the ouput correctly and when i broadcast the same through email,in work precalculation tab, again it is asking me to enter variable values.I have done that and executed. But I am not able to receive any email.Infact,after taking 3 mnts it showing Timed out error.Kindly,suggest me with a solution to this. Where should I exactly enter variables?
Kindly,give me a solution for this.
Thanks,
Mohan Chand Reddy A

Hai Shakir,
First i thank q for ur reply to my question.But is it correct that we should assign Variables only in the Workbook Precalculation tab?Some one are suggesting like variables can be given both in foreground calculation i.e., while creating a workbook and also we should give the same variables in the workbook precalculation tab.But in one document, i found there is no variable assignment tab in the Broadcasting settings.It means they might have given variables in the workbook creation itself.
Please,reply me.It's very urgent.
Thanks,
Mohan Chand Reddy A

Variable assignment screen in Precalculation server

I am not able to get solution for this problem from long time. Can anybody tell me...
How to setup variable assignment screen in Precalculation server?
Currently when i click Create Variable assignment in precalculation tab of broadcaster... it gives error that error loading 0ANALYSIS_PATTERN template.
Plz help. whole points will be assigned.

I made a copy of 0ANALYSIS_PATTERN, and changed spro settings, wkbks are broadcasting but only problem is i am not able to assign variables, because no popup screen coming for creating variables. i also wrote program for table RSRVARIANT.

Template declaration error when variable assigned is the same as variable declared

Hi Fedor,
In comm-central repository, when compiling mozilla/mfbt/Compression.cpp using -std=c++11, it results in an error as follows:
"../dist/include/mozilla/CheckedInt.h", line 400: Error: Unexpected type name "T" encountered.
"../dist/include/mozilla/CheckedInt.h", line 400: Error: value is not defined.
"../dist/include/mozilla/CheckedInt.h", line 400: Error: No direct declarator preceding ">".
"../dist/include/mozilla/CheckedInt.h", line 400: Error: A declaration does not specify a tag or an identifier.
"../dist/include/mozilla/CheckedInt.h", line 400: Error: Default template argument cannot be specified on the definition of a class template member that appears outside of its class.
"../dist/include/mozilla/CheckedInt.h", line 400: Error: Templates can only declare classes or functions.
"../dist/include/mozilla/CheckedInt.h", line 413: Error: No primary specialization for partial specialization NegateImpl<T, 0>.
"../dist/include/mozilla/CheckedInt.h", line 416: Error: Too many arguments for template mozilla::detail::NegateImpl<T>.
8 Error(s) detected.
After a check on the file CheckedInt.h, it was narrowed down to the following code that resulted in the failure (the variable assigned, isSigned is the same as variable being declared) :
template<typename T, bool IsSigned = IsSigned<T>::value>
struct NegateImpl;
This code, however compiles without problems in gcc-4.8.
A workaround was to use a different variable declared in the template (e.g. bool IsTSigned = IsSigned<T>). But I just wanted to be sure whether is this a bug in 12.4 Beta or whether coding rules in templates do allow this kind of declaration? Kindly advise. Thanks.
Regards,
Brian

Hi Steve,
The declaration made below is not valid when -std=c++11 is not used (it causes the same compile-time errors when using July Refresh):
template<typename U> class IsSigned;
template<typename T, bool IsSigned = IsSigned<T>::value>
struct NegateImpl;
So far, the workaround was to use a different variable declared in the template (e.g. bool IsTSigned = IsSigned<T>).
Regards,
Brian

How to display a BPEL variable using Java Embedding

Hi, hope someone can help, I'm sure this is something very simple but for the life of me can't seem to find it through the tutorials including the Dev guide.
Question
=======
How can I display user defined and BPEL variables in the process activity "Java Embedding" ?
ex: System.out.println(bpws:getVariableData("myDatabaseParameterVariable")
This example doesn't work but this is basically what I am trying to achieve.
I would appreciate any help with this.
Rookie

Actually that's all the code I have.... System.out.println(myDatabaseArg);
myDatabaseArg is a simple parameter defined in the database adapter configuration wizard which is used as a criteria to retrieve data.
Just before I invoke the Read I use the Java Embedding to display the content of the parameter.

BPEL Variables in to Transform activity (XSL)

Hi,
I need to access a BPEL variable from within a Transform activity (XSL).
I need an output like this:
<XML>
<val1>1</val1>
<val2>2</val2>
<val3>3</val3>
<val4>4</val4>
</XML>
Val1 and val2 is reachable from the xsd in the Transform activity (source variable). A DB-adapter is used to provide these data.
Val3 and val4 is present in the BPEL, within BPEL variables.
I have created a Transform activity with source = result of DP-adapter (val1 + val2), but will then need to get val3 + val4 (BPEL vars) from inside the Transform activity as well.
How can I do this ?
I have tried passing the variables in as parameters, but can't get this to work. I either only get the parameters, or only get the values from the DB-adapter, as it seems I only can have 1 source.
Similar thread, but with no answer:
Global Variables in to XSL

Thank you for answering.
The link you're referring to is the thing that I mentioned that I couldn't get to work.
Works fine when just passing parameters, but when I already have a source (like my DB-adapter output), and want the parameters as well, it's getting tricky. Seems there can only be 1 source: Parameters or DB-adapter output.
What I need is values from a source (DB-adapter output) + be able to send BPEL variables to the same Transform activity (XSL).
Have you tried this ? Is it at all possible ?

Variable Assignment in General Precalculation tab of BI 7.0 broadcaster

Hi,
In the broadcast setting, under General precalculation tab variable values can be set up. When we are clicking create variable values, screen with all the variables of the query were coming.
After entering data in the variables and clicking OK, values are not being transferred to the Broadcast setting. The variable page remains like that with out transferring to the Pre Calculation tab.
We are on SAPKW70020.Distribution type used is Broadcast email, output fornat is MHTML. I tried with other output types, but same result.
We are using query as the object type for creating Bex Broadcaster.
Has anyone ran into this issue before?
Thanks & Regards,
Pradeep

Hi Mohan,
You have opened up an old post, so many responses might be to answer the initial question.
However, to answer your question, when you click 'Create' next to the 'VAR01 in Variable assignment, what you see is a popup window with the 'Ready for Input' variable present in your query/ workbook/ template, which is the same variable screen which you get when you execute the same query/ workbook/ template independently. You can then enter values for those variables and click OK, to save it and to be passed to the broadcasting setting. The broadcast would then happen for the same variable values.
However, if you face the issue mentioned by Pradeep, then after clicking OK, you can cancel the popup window. The values of the variables would still be passed.
After the popup window closes, you can see the 'Create', you initially saw, replaced with 'Change'. This means the values are saved.
Hope it helps.
Thanks,
Abhishek.
