WSO2 ESB-XML到MySQL数据库

Question

I need a solution for a problem: I just tried this example for the WSO2 ESB and it is working: http://wso2.org/library/articles/2011/01/wso2-esb-example-file-processing

But I like to use an XML file as input and write this to a MySQL-DB. The XML-file looks like this:

<?xml version="1.0" encoding="utf-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
  <Name>word</Name>
  <Surname>processor</Surname>
  <Phone>12333</Phone>
</soapenv:Body>
</soapenv:Envelope>

If i put this into my "in"-folder the file will be moved to the "out"-folder, but nothing is written into the database. There is no error message.

My Proxy-Service:

    <proxy xmlns="http://ws.apache.org/ns/synapse" name="FileProxy" transports="vfs" statistics="disable" trace="disable" startOnLoad="true">
   <target>
      <inSequence>
         <log level="full"/>
         <clone>
            <target sequence="fileWriteSequence"/>
            <target sequence="databaseSequence"/>
         </clone>
      </inSequence>
   </target>
   <parameter name="transport.vfs.ActionAfterProcess">MOVE</parameter>
   <parameter name="transport.PollInterval">15</parameter>
   <parameter name="transport.vfs.MoveAfterProcess">C:/wso2esb/testordner/out</parameter>
   <parameter name="transport.vfs.FileURI">C:/wso2esb/testordner/in</parameter>

   <parameter name="transport.vfs.ContentType">text/xml</parameter>
   <parameter name="transport.vfs.ActionAfterFailure">MOVE</parameter>
   <description></description>
</proxy>

And my Sequence:

    <?xml version="1.0" encoding="UTF-8"?>
<sequence xmlns="http://ws.apache.org/ns/synapse"
          name="databaseSequence"
          trace="enable"

   </log>

               <statement>

                  <parameter expression="//csv-record/name/text()" type="VARCHAR"/>
                  <parameter expression="//csv-record/surname/text()" type="VARCHAR"/>
                  <parameter expression="//csv-record/phone/text()" type="VARCHAR"/>
               </statement>
            </dbreport>
         </sequence>
      </target>
   </iterate>
   <log level="full" category="DEBUG"/>
</sequence>

I thought this would be a simple problem, but I'm not able to get it... Like I said, it's working with a normal text-file, but not with XML. I tried different thinks and have no idea what else I could try... Does someone know what's my mistake?

Update:

The log from the console:

Smooks config:

    <param name="fields" type="string-list">name,surname,phone</param>

</smooks-resource-list>

I also changed the code of the databaseSequence above.

Thank you.

Answer 1

Your proxy service looks ok. But I have few concerns.

1. Why have you put the sql query as CDATA. Please see the sample available here .
2. You have not mentioned the database name in the connection url. May be it is not a problem since you have used the database.table format in your sql query.
3. After fixing and 1 and 2, if the issue still exists, try your proxy with only one sequence. ie Avoid the file write sequence temporarily and try only with the dbwrite sequence.

You can also log the entries which you are going to insert before the DBReport mediator. ie Right after the smooks mediator, put a log mediator and log the name, surname and phone. This will make sure you are trying to insert values which are correctly extracted from the message.
