Http adapter metadata in java mapping

Question

Hi,  I'd like to read the httpheaders in my java mapping.
How can this be done?
I have tried the follwing in the execute method
       trace = (AbstractTrace)param.get(
         StreamTransformationConstants.MAPPING_TRACE);
      DynamicConfiguration dc = (DynamicConfiguration)param.get( 
          StreamTransformationConstants.DYNAMIC_CONFIGURATION);
          Object obj = (Object) param.get(
            StreamTransformationConstants.CONTENT_TYPE);
          trace.addInfo(obj.getClass().toString()); 
          // namespace http://sap.com/xi/XI/System/File
        // propertyname Directory, Filename
          trace.addInfo("Start");
          //DynamicConfigurationKey dck = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/HTTP","httpHeader");
               //trace.addInfo("has key httpHeader");
               Iterator it = dc.getKeys();
               while (it.hasNext()) {
                    DynamicConfigurationKey el = (DynamicConfigurationKey) it.next();
                    trace.addInfo(el.getNamespace() + " " + el.getName());
                    if (el.getNamespace().equals("http://sap.com/xi/XI/System/HTTP") ){
                         if (el.getName().equals("httpHeader") ){
          //if (dc.containsKey(dck)) {
          trace.addInfo("After dyn conf");
No keys are found.
Hope someone can help
Best regards /Otto

Hello, thanks for your help.
I have the following in my trace in the log SXMB_MONI
Depending on the charset and the content-type I'd like to take different action.
I use a visualbasic script to send a file to XI.
This file may be xml, zip, text or whatever. In this test I used a utf-8 text file. XI can put it into the pipe binary clean, and then I use a java program to unpack it and wrap it in xml for further processing. The file is put in the http post data, which is by definition binary clean.
Of course I can not route on a binary file, so I have to configure routing etc appropriately.
Looks like the trace api only allows for writing to the trace, not reading.
