Logging the raw XML of a SOAP request/response using JAX-RPC

Question

I'm using JAX-RPC and wanted to know if there is a way to make JAX-RPC print the raw SOAP Request/Response for debug purposes.

I saw that JAX-RPC uses log4j but did not see which logger I should turn on with DEBUG to view the message before it is sent.

If you are using Apache Axis, here is the log4J configuration you can use:

<appender name="wsAppender" class="org.apache.log4j.RollingFileAppender">
    <param name="File" value="${catalina.base}/logs/MY_APP-ws.log" />
    <param name="Append" value="true" />
    <param name="MaxFileSize" value="20MB" />
    <param name="MaxBackupIndex" value="10" />
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="%d %m%n" />
    </layout>
      <filter class="org.apache.log4j.varia.StringMatchFilter">
              <param name="StringToMatch" value="MY_SPECIFIC_WSProcessRequest" />
              <param name="AcceptOnMatch" value="true" />
      </filter>
    <filter class="org.apache.log4j.varia.DenyAllFilter"/>
</appender>

<logger name="org.apache.axis.transport.http.HTTPSender" additivity="false">
    <level value="DEBUG" />
    <appender-ref ref="wsAppender"/>
</logger>

Change MY_SPECIFIC_WSProcessRequest for the specific value matching the XML request you want to log.

我建议您实现一个Handler ，该Handler将具有handleRequest和handleResponse方法（ doc ），可以重写该方法来操纵您的请求/响应（有关如何使用处理程序的文档 ）。
