Hi All,
I am sure most of you ask me to search this issue in the forum. I did search a lot for this issue and I concluded from my knowledge experience that this error is related to "Invalid web service response". However, the web service team says everything is normal from their side.
Before writing a lot, let me emntion the exception below...
| Code: |
Caught exception and rethrowing. Error occurred in ImbSOAPRequestHelper::makeSOAPRequest(). WebService Request Exception. Error Making SOAP JNI Call:
Axis2Requester_processResponseMessageSync.
Axis2Requester_processResponseMessageSync.

Based on my experience and the info I could find in the forum, I informed the web application team that this failure happened due to an invalid response, in this case, it is an html response from the web server where the web service is located.
Am I right about this? or anything else can also cause this issue? We got this exception 4 times and I need to be sure that this is not a broker related issue before working/arguing with the web service team. Please suggest me, if I need to do anything elsse from my side to find out the root cause for this... This is happening in PROD.
Thanks

Turn off validation of your nodes, and connect Trace nodes to all terminals, then post the output of the terminals.
Else, use UserTrace to derive the same info. Or TCPMon to see what the wire holds.

Often, when TIM/TAM junctions are not set properly, your WMB SoapRequest gets redirected to a web page that writes html to tell a human that he cannot access the site.

1. Also check to be sure - if you are using HTTPS - that your SSL certs are current and correct, stored properly in the truststore.
2. If the Web Service is hosting HTTPS and you are calling HTTP, then you would possibly also get the HTML message. Make sure, by looking at the mqsireadbar output, that if the WS is HTTPS your URL is also HTTPS on the SoapRequest node. Don't trust the toolkit view, actually do an mqsireadbar.

Two more troubleshooting tips:
1. Use curl on the WMB system by redirecting an input SOAP request from a file on the file system and check to see proper response.
2. Use SoapUI from your desktop to see if you can hit the Web Service and get a proper response.

I took a user trace and got the below info..

How can I read this data above posted one? I tried converting it from hex to string online but could not convert all data... however, I could get some clue that the web service sent some <html> data...
Please help me read this so that I can send this to the web app team so that they can do something to resolve this...
I have the bit stream data also but I could not post this here....
Thanks

you need a HEX-Decoder.
Search on google.
There you find e.g. this.
The part decoded here is an HTTP-Header, btw.
If you see "Internal Server Error" on the CLIENT you likely need to look into the SERVER log(s) for more error details.
That is because a Server likely doesn't (want) to tell you / to let you too many (of his) internal (error) details. It's just likely sends you "there was an internal error on our side, pls look into the server logs / we will look into the server logs".

I keep a perl script with
| Code: |
while (<>) {
print unpack("H*",$_);
} |
lying around for just such a purpose. |

Excellent, thanks for providing that (probably you do not want to submit your data to (some random) web page on the internet/WWW).
@OP: But you should also use SOAP-UI (or CURL) for Testing your web service (as lancelotlinc suggests)... and not only test a web service with broker. |

@msiuser, and @mqjeff,
Thanks a lot for the info. Finally, I have the <html> response from the service and sent the web service request and the html response to the web service team. Will see how we can resolve this issue together.
Thanks again for the info.
Thanks
