Solved: Message Listener - Web Service

Former Member · ‎09-20-2010

Hi All ,

I'm using MII 12.1 , and I'm trying to post messages from transaction to the message listener of same server .

I tried most of the options informed through so many blogs , but I'm getting the response as a FATAL ERROR and MESSAGE WAS NOT RECEIVED as a string response and the xml response is null .

The url :

http://<server Name>:<port>/XMII/Illuminator?service=WSMessageListener&mode=WSMessageListenerServer&NAME=<message name>&Content-Type=text/xml

and POST Data is an XML of a Tag Query.

Still , it is showing the above error.

Would anyone suggest a solution for it please.

Hi,

if you are using the HTTP Post action in your transaction to call the WSMessageListener webservice, have you set Encoding = UTF-8? I have also used Content-type "text/xml" in the Configuration of the action instead of adding it to the URL.

Are there any entries in the NetWeaver Logs when this error is displayed in your tran?

By the way, you can add "&Session=false" to you URL to avoid MII creating a session for every webservice call.

Hi Otto ,

I'm clear with message clean up rules .But , My actual Query is :

In real time scenario , suppose I'm receiving a message based on which I'm inserting data into an external database like Oracle. I have to delete these messages only after success fully Inserting data inti external database Server. If the connection is failed then the data buffering feature will store the data and retry based on the configuration we set in the Data server .Now if the messages are keep on adding and execcuting a transaction so that the data in buffer also gets added until the connection establishes(active) again.

In Such scenario the MII database , is it capable of handling entire data ?

How do we check and delete the data in Data buffer to update Messages using clean up rules in message services?

Thank you Otto , I got it now.

May I know where these messages are getting stored , like is it the same MII Database in which the Data Buffering Entries ,Under Data Services , are stored?

Is there any way to extend its capacity as in real time scenario very huge amount of data is to be stored and Processed. Like Customisation of the MII data base or something.

Hi All ,

thanks for your suggestions. I found something Crazy that It worked now even though I violated all suggestions except removing the default Content Type. I don't know why it wasn't working.

I have a doubt : I thought the message Name should be Unique , but it is accepting Multiple Messages with same Name . Is there any Procedure to validate this ?

Thanks everyone for your immediate response.

Otto : I tried Encoding = UTF-8 , "&Session=false"

Good : I included IllumLoginName and IllumLoginPassword in the URL

Schrampf : I tried "text/xml" in place of "application/x-www-form-urlencoded" in Content Type Input

But still I'm getting the following Error Log in NWA :

Message was not received
