Hi binh,
I might be wrong..but in any bpel process files(samples in ODE/ some
other references) , authors haven't declared the local namespace(dont
know term is right) for partnerlinks. All partnerlinks'
namespace(relevant WSDl file's target namespace) are defined at the
start as i said in previous mail.
You are invoking the 'TestString' service..so you need to include its
namespace at the top.(?).
Ps: Another reason is, i opened your testBP.bpel file with eclipse
editor,it shows that you defined two partnerlinks but for StringPL it
states no partnerlink type and role...
Regards,
Ratha.

Hi Ratha,
Yes, I misunderstood your idea. Anyway, I am afraid that you did not
carefully the part of code that declare the partnerLink.
file testBP.bpel
<partnerLinks>
<partnerLink name="StringPL"
xmlns:*tns*="
http://enterprise.netbeans.org/bpel/StringWSServiceWrapper";
partnerLinkType="*tns*:*StringWSLinkType*"
partnerRole="StringWSRole"
initializePartnerRole="yes"/>
As you can see, the local namespace tns has been declared end references to
StringWSLinkType defined in the file StringWSServiceWrapper. This local
namespace is different compared to global namespace tns declared above at
the beginning of the file bpel.
In addition, the first operation testOneWay also in the partnerlink StringPL
runs well, so I think that maybe the error is not there.
Anyway, thank you very much for your effort in finding my error! I think we
are closer to it.
Cheers,
Binh.

Hi binh,
I think you misunderstood me.. I meant you shoud define the WSDL namespaces
with the process name tag.
<process
name="testBP"
targetNamespace="http://enterprise.netbeans.org/bpel/StringBP/testBP";
xmlns:tns="http://enterprise.netbeans.org/bpel/StringBP/testBP";
xmlns="http://docs.oasis-open.org/wsbpel/2.0/process/executable";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:str="http://MyWS/";
xmlns:ns0="http://docs.oasis-open.org/wsbpel/2.0/process/executable";
xmlns:ns1="http://j2ee.netbeans.org/wsdl/testBP";>
In the above segment have you mentioned the StringWSServiceWrapper.wsdl
file?
It should be like this,
<process
name="testBP"
targetNamespace="http://enterprise.netbeans.org/bpel/StringBP/testBP";
xmlns:tns="http://enterprise.netbeans.org/bpel/StringBP/testBP";
xmlns="http://docs.oasis-open.org/wsbpel/2.0/process/executable";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
-------------------------------------------------
-------------------------------------------------
xmlns:ns5="http://enterprise.netbeans.org/bpel/StringWSServiceWrapper";>
and use at the partner link definition as,
<partnerLink name="StringPL" partnerLinkType="ns5:StringWSLinkType"
partnerRole="StringWSRole"/>
With your earlier design, StringPL partnerlink didn't have partner role or
PartnerLinkType.
You might think, then why its right for the 2nd partnerlink. But you are
using same namespace tag for both "*tns*"
(bpel and the wsdl(which you defined at the top))
Hope you will get it...
thanks,
ratha.

Hi Ratha,
Actually, the partnerLinkType StringWSLinkType is defined in another WSDL
file that I forgot not to attach in the last mail. Here is the file:
file StringWSServiceWrapper.wsdl
<?xml version="1.0" encoding="UTF-8"?>
<definitions
name="StringWSServiceWrapper"
targetNamespace="
http://enterprise.netbeans.org/bpel/StringWSServiceWrapper";
xmlns="http://schemas.xmlsoap.org/wsdl/";
xmlns:tns="http://enterprise.netbeans.org/bpel/StringWSServiceWrapper";
xmlns:plnk="http://docs.oasis-open.org/wsbpel/2.0/plnktype";
xmlns:ns="http://MyWS/";>
<import location="StringWSService.wsdl" namespace="http://MyWS/"/>
<plnk:partnerLinkType name="StringWSLinkType">
<plnk:role name="StringWSRole" portType="ns:StringWS"/>
</plnk:partnerLinkType>
</definitions>
--------------------
Thank you very much for your attention and suggestions.
Please check it again for me, because I really need to fix this issue!
Cheers,
Binh.

Hi Binh,
I can find an error in your partnerlink definition. You defined as,
/<partnerLinks>
<partnerLink name="StringPL"
partnerLinkType="tns:StringWSLinkType"partnerRole="StringWSRole"
initializePartnerRole="yes" xmlns:tns="
http://enterprise.netbeans.org/bpel/StringWSServiceWrapper"/>
<partnerLink name="TestPartnerLink" xmlns:tns="
http://j2ee.netbeans.org/wsdl/testBP";
partnerLinkType="tns:testBPLT" myRole="testBPPortTypeRole"/>
</partnerLinks>
/StringPL is wrong.. Name space should be the relevant WSDL files name
space..You need to define at the start (with <bpel:process name> tag)
So your StringPL doesnt have partnerlinktype or partner role...May cause
an
error..
Thanks.
regards,
ratha.

--------------------
In the testBP.bpel file, the value of variable TestStringIn is always
NULL
event after it has been assigned by Non NULL value.
I do not know how to assign it correctly?
Any advice is appreciated!
