How to catch a request SOAP message?

[Pablo Zuazua]

Hi everyone, I'm building a web application that will receive a SOAP message and will reply with another SOAP message. The SOAP message I will receive from a external provider is like the next one:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://www.huawei.com/schema/syncorder/v1-0/" xmlns:tns="http://www.huawei.com.cn/schema/common/v2_1"> <SOAP-ENV:Header> <tns:NotifySOAPHeader> <tns:spId>35000001</tns:spId> <tns:serviceId>35000001000001</tns:serviceId> <tns:spRevId> </tns:spRevId> <tns:spRevpassword> </tns:spRevpassword> </tns:NotifySOAPHeader> </SOAP-ENV:Header> <SOAP-ENV:Body> <ns1:SyncOrderRelationExt> <ns1:userID> <ns1:UserID> <ns1:ID>12346579801234567890</ns1:ID> <ns1:type>0</ns1:type> </ns1:UserID> </ns1:userID> <ns1:SPID>35000001</ns1:SPID> <ns1:productID>11111111111</ns1:productID> <ns1:serviceID>35000001000001</ns1:serviceID> <ns1:serviceList>44444444</ns1:serviceList> <!--OP--> <ns1:updateType>1</ns1:updateType> <ns1:updateTime>55555555555555</ns1:updateTime> <ns1:updateDesc>222222</ns1:updateDesc> <!--OP--> <ns1:effectiveTime>1256192581666</ns1:effectiveTime> <!--OP--> <ns1:expiryTime>5555555</ns1:expiryTime> <!--OP--> <ns1:extensionInfo> <!--OP--> <ns1:NamedParameterList> <ns1:NamedParameters> <ns1:ArrayOfNameParameter> <ns1:NamedParameter> <ns1:key>notifyAddress</ns1:key> <ns1:value>http://10.40.63.16:9999/syn</ns1:value> </ns1:NamedParameter> </ns1:ArrayOfNameParameter> </ns1:NamedParameters> </ns1:NamedParameterList> </ns1:extensionInfo> <ns1:notifyAddress> </ns1:notifyAddress><!--OP--> </ns1:SyncOrderRelationExt> </SOAP-ENV:Body> </SOAP-ENV:Envelope>

and the response it's like this:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:v1="http://www.huawei.com/schema/syncorder/v1-0/"> <SOAP-ENV:Header/> <SOAP-ENV:Body> <v1:SyncOrderRelationExtResponse> <v1:hRet>0</v1:hRet> </v1:SyncOrderRelationExtResponse> </SOAP-ENV:Body> </SOAP-ENV:Envelope>

I'm able to send the response, you can check it here: Webpage. But I don´t know how to catch the request SOAP message, ¿how can I obtain it?, because I must store some of the data of the message.

I know my solution it's not the best but I had to built it fast, particularly the sending message part.
Thanks in advance.

PD: I'm using JAVA, jsp, NetBeans and Tomcat.

I already solved this issue, I did what it follows:

I created a servlet that it's gonna be the entry point.

This servlet intercepts the message.

I use the request object to get the InputStream.

ServletInputStream sis = request.getInputStream();

Then I have to change the content to a String.

String contenido = convertStreamToString(sis);

import java.util.Scanner;

private String convertStreamToString(InputStream is) {
        return new Scanner(is).useDelimiter("\\A").next();
    }

Now I can extract the data I want from the String.

And last I serve the response.

PrintWriter out = response.getWriter();
try {
   out.println("<SOAP-ENV:Envelope xmlns:SOAP-ENV=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:v1=\"http://www.huawei.com/schema/syncorder/v1-0/\">");
   out.println("<SOAP-ENV:Header/>");
   out.println("<SOAP-ENV:Body>");
   out.println("<v1:SyncOrderRelationExtResponse>");
   out.println("<v1:hRet>0</v1:hRet>");
   out.println("</v1:SyncOrderRelationExtResponse>");
   out.println("</SOAP-ENV:Body>");
   out.println("</SOAP-ENV:Envelope>");
} finally { 
   out.close();
}

Maybe this helps someone who has the same problem or similar.
