Hi,:o

I am learning about webServices in 7.1 and came across a small glitch…well, i got a sample wsdl document from net and m trying to created a Provider and Consumer from dat.

The WSDL i have used is basically one to get the day given any date (i.e, it returns Friday if the date i give is ‘2009-01-16’ ).

But when I am trying to run the connector, it is giving a NullPointerException.

I know I’ll figure it out somehow, but definitely will appreciate some inputs!!

Did you check the IS error logs to get more debug information??

Hi,

I checked the error log and it is as follows!!

I think that the error is due to the fact that the site given in the namespace is inaccessible…
Any inputs?

Hi,

Finally I got the solution for this one…Told u i will, dint I?
Turns out that the problem was with the wsdl file I used…instead of giving <soap:binding style=“rpc”> I’d given it as <soap:binding style=“document”>

Here s the correct sample wsdl document!!!

<definitions name =“DayOfWeek” targetNamespace="[URL=“http://www.roguewave.com/soapworx/examples/DayOfWeek.wsdl”]http://www.roguewave.com/soapworx/examples/DayOfWeek.wsdl[/i][/URL][I]"
xmlns:tns="[URL=“http://www.roguewave.com/soapworx/examples/DayOfWeek.wsdl”]http://www.roguewave.com/soapworx/examples/DayOfWeek.wsdl[/i][/URL][I]"
xmlns:soap="[URL=“http://schemas.xmlsoap.org/wsdl/soap/”]http://schemas.xmlsoap.org/wsdl/soap/[/i][/URL][I]"
xmlns:xsd="[URL=“XML Schema”]http://www.w3.org/2001/XMLSchema[/i][/URL][I]"
xmlns="[URL=“http://schemas.xmlsoap.org/wsdl/”]http://schemas.xmlsoap.org/wsdl/[/i][/URL][I]">













<soap:binding style=“rpc”
transport="http://schemas.xmlsoap.org/soap/http"/>

<soap: operation soapAction=“getdayofweek”/>

<soap:body use=“encoded”
namespace="[URL=“http://www.roguewave.com/soapworx/examples”]http://www.roguewave.com/soapworx/examples[/i][/URL][I]"
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>


<soap:body use=“encoded”
namespace="[URL=“http://www.roguewave.com/soapworx/examples”]http://www.roguewave.com/soapworx/examples[/i][/URL][I]"
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>





Returns the day-of-week name for a given date


<soap:address location="http://localhost:8090/dayofweek/DayOfWeek"/>

This is just a sample wsdl document that I came across in the net.
Don’t forget to provide the logic for the provider service in providerName_:services folder, else it won’t work!!

Peace, ppl!

Well gud catch…BTW,you forgot to change this in the corrected wsdl above …
<soap:binding style=“document”

HTH,
RMG

Thnx RMG, but I have posted the document that was working, so I dnt no where the clarification is.
Please enlighten me.
Cheers!

you said that after changing <soap:binding style=“rpc” to <soap:binding style=“document” it worked isn’t?..but the sample you pasted above still shows rpc…never mind its just a side note.

HTH,
RMG

No no RMG, u got me wrong!

I sd after changing it to “rpc” it worked, before it ws “document”, now it is “rpc”.

OK never mind…I thought your words sounded other way…
