Occasionally - BPEL variable is empty

We have a process that prepares a large variable (purchase order) via transform for an invoke. Most of the time it performs with no problems but sometimes it gets in a state where that transform will create a totally empty output.
This continues with each new instance until restarting the server which fixes the issue. Any ideas what would cause this sporadic problem?
Thanks,

Hi,
I have seen very similar behaviour with variable initialisation in BPEL, and it does seem to clear out after a composite redeploy or a server restart.
It looks like a bug, but I have no idea how to reproduce, so it's hard to investigate around something that happens only occasionally with unknown reason...
Hope someone can find a way to reproduce it... Then it can possibly be fixed..
Cheers,
Vlad

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 ?

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 :

   </bpelx:exec>they dont use namespaces in the xpath-expression, can you try that ?

Hotsync occasionally results in an empty calendar in the Palm desktop software.

Hotsync occasionally results in an empty calendar in the Palm desktop software.
Updated to most current version - 6.2. That did not help.
Downgraded to 4.2.1 based on some discussions I read here, but that didn't help either.
Hotsync logs show successful sync when the problem occurs.
Re-syncing repopulates the calendar and gives an error about dates older than 1971.
Anyone have any suggestions?
Thank you!

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.

ICM - CVP single step transfer, peripheral variables are empty

Hi,
The we do the Single Step Transfer, peripheral variables are empty when the call reachs the CVP. Please help
The call scenario:
1-      Customer dial 181
2-      Call queued on ICM
3-      Agent receive the call
4-      Agent do single step transfer and send the call (with data(PV1..PV10)) to CVP through ICM
5-      CVP play the number received from ICM
Currently, data set in the PV1-PV10 are empty once reach the ICM…
I need the these data to be available to play it to the caller..
I am using:
CAD 7.2
CVP 7.2

If the call goes to an agent do you see the data? Are you using a cti rp to make the transfer or dnp?

Accessing BPEL variables in XSL

Hi,
Did anyone have success accessing BPEL variables in XSL? If so can
you please let me know how you did it? I tried bpws:getVariableData
without much luck.
Any information will be of great help.
Thanks
Raj

I don't think that's really what XSL is for. It's really about taking a single XML document, and generating another XML document, based on the first.
If you want to pass in variables from BPEL, then write a complex type that contains the main XML document you need, plus all the other inputs you need.
As an example, I was doing some XSL work and needed to also supply it with a default date to set when nothing else was present.
My complex type would have been something like:
<complexType name="ProcessDataInputType">
<sequence>
<element name="defaultDate" type="date"/>
<element name="data" type="tns:MyDataType"/>
</sequence>
</complexType>

BPEL Process returns "empty variable/expression result."

Hi,
I have an Asynchronous BPEL Process which uses a DB Adapter (which in turn uses a custom SQL Procedure) to insert a value in to a table and return a sequence value generated in the procedure back to the BPEL Process. The process inserts the value in to the table but the sequence is not returned back and i get the below error,
<selectionFailure xmlns="http://schemas.xmlsoap.org/ws/2003/03/business-process/">

</summary>
</part>
</selectionFailure>
If i see the process flow the invoke activity shows the sequence value is returned from the procedure but when the invoke activity passes that value to the Assign activity its lost and the above error is displayed.

Aassign xsi:nill values from element to BPEL variable - Urgent..Plz..

Hi all,I have a BPEL process which calls a Webservice,and at the end it transforms the output of the Webservice to the Output Variable in my BPEL process,but the thing is this process retuns elements with xsi:nil="true" and I get an error which says
*Could not initiate the BPEL process because the input xml is not well formed, the reason is :
Error parsing envelope: (4, 3679) Namespace prefix 'xsi' used but not declared. Please correct the input xml.*
I have verified the WSLD,.bpel file,the xsd..they all have xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
Heres the code of the assign
<from xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
variable="Invoke_P_getlV_OutputVariable"
part="parameters"
query="/ns7:getCViewResponse/ns7:getCViewReturn"/>
<to xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
variable="outputVariable" part="payload"
query="/ns1:GetOfferResponse/ns1:getCVResponse/ns1:getCViewReturn"/>
Please temme how do I get this to wrk...I need to get this working immediatly..

If you need to "clean" some xml from null values (empty tags) you can create an XSLT (like RemoveNullTags.xsl) with the following code:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:apply-templates select="@*|node()"/>
</xsl:template>
<xsl:template match="@*|node()">
<xsl:choose>
<xsl:when test="normalize-space(.)">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:when>
<xsl:when test="count(./*)">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:when>
<xsl:otherwise>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
This xslt will remove all the empty tags on your XML. So after you create this and paste it on your project, you need to use it into an ASSIGN activity like this:
<assign name="Remove_Nulls">
<copy>
<from expression="ora:processXSLT('RemoveNullTags.xsl',bpws:getVariableData('inputVariable','payload'))"/>
<to variable="inputVariable" part="payload"
query="/ns2:writeCollectedDeleteElement"/>
</copy>
<copy>
<from expression="ora:processXSLT('RemoveNullTags.xsl',bpws:getVariableData('inputVariable','payload'))"/>
<to variable="inputVariable" part="payload"
query="/ns2:writeCollectedDeleteElement"/>
</copy>
</assign>
As you can see in this sample, i make 2 copy operations because i have xml arrays, so i need a copy operation for each child the xml element have.

How to put SOAP body in BPEL variable

Hi everybody,
I have a BPEL process which needs to pick up a SOAP-message from a queue, transform the body and send the result to a webservice.
The process is running deployed and picks up the soap message. In the receive action I see the SOAP message - envolope, header and body - as expected (shown below).

Error in Passing BPEL variable Contents to BPEL Transform (XSLT)

Hi,
Problem Statement:
·     I want to Transform data, from schema1 to schema2.
·     Schema1 is basically a collection lets say collection of A. in XML terms, it has multiple same type of child elements under the root element.
·     Schema2 associated with each child element of Schema1.
·     In the Loop, I want to iterate through the schema1 data and iteration count would be as much as number of child elements in it.
·     Pick one child element (using index in XPATH) and use it to associate with Schema2 elements.
·     In this process I wanted to pass 2 parameters to BPEL Transform activity using properties datatype. (ref: http://blogs.oracle.com/rammenon/2007/05/07)
·     However it is not realizing the parameters passed to it.
Please also suggest me a location to upload the related code for any verification.
Please suggest the flaw in this and suggestions to rectify.
Thanks
Regards
Joy

Example counting nodes.
ora:countNodes('Invoke_FileSyncRead_SynchronousRead_OutputVariable','Root-Element','/ns1:Root-Element/ns1:SiteInfo')
Set that to Integer variable $count.
Then set new variable type integer $interator = 1.
That will give you a proper loop counter for your payload.
AS far as mapping only certain elements, I would just transform 1st, then pick out what you need with an explicit assign activity to whatever you want to pass that to.
Hope that helps.

My code does the following calls:
Locator locator = new Locator("default", "bpel");
WhereCondition where = new WhereCondition(SQLDefs.CI_cikey + " = ?");
where.setString(1, taskId);
IInstanceHandle[] instances = locator.listInstances( where );
IInstanceHandle instanceHandle = instances[0];
System.out.println(instanceHandle.getTitle());
HashMap inst = (HashMap)instanceHandle.getField("PatientRecordVariable");
XMLElement dataXML = (XMLElement)inst.get("payload");
String data = XMLHelper.printXML(dataXML);
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.

When I display the debugTrace message for the process instance using
System.out.println(instanceHandle.getDebugTrace());
it gives me this:

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.

Bpel variable

HI,
I am trying to create a variable in the bpel and the variable is of type 'Element'.Imported the schema file from MDS.when i am trying to compile,it is showing error as *Error(40): XML element "{http://oracle.com/service/B2BHeader}B2BHeader" of variable "Variable2" is not defined*.
So,any suggestions would be great.
Regards,
Praveen

Hi Praveen,
Is the xsd you tried to use valid? Can you check by creating a dummy SOA composite in where a BPEL component is using a WSDL based on the xsd schema you try to use? Tried to deploy and see if this works. Of course in the BPEL component make sure you assign input to output to make it compile.
Is your MDS correctly configured in adf-config.xml file? If your local MDS is point to the database make sure the schema is deployed to MDS. In case of file based make sure the xsd is stored in the correct MDS file directory.
Thanks
Sander
