Soap.name.NameImpl incompatible with SOAPHeaderElement

Question

Hi , I am trying to decompose a SOAP message and
I am getting the following exception :
Exception in thread "main" java.lang.ClassCastException: com.sun.xml.messaging.saaj.soap.name.NameImpl
     at com.acme.dw.tri.MessageReader.displayAttributes(MessageReader.java:128)
     at com.acme.dw.tri.MessageReader.unmarshallMessage(MessageReader.java:106)
     at com.acme.dw.tri.MessageReader.main(MessageReader.java:156)
Here is the code :

}And here is the list under the "Order and Export" tab
in Eclipse --> Project --> Properties --> Java Build Path

JRE System Library [jre1.5.0_08]
Thanks in advance for your help.
Of course, if you know of a better / simpler way to do this, that
would help as well.

Hi,
and update:
in 10.1.3.3.2
     <parameters>
          <parameter name="PM_cycle_count" dataType="number"/>
     </parameters>
<element name="CF_CYCLE_COUNT" value="PM_cycle_count" function=""/>
works perfect!!!
in 10.1.3.4.1
<element name="CF_CYCLE_COUNT" value="PM_cycle_count" function=""/>
gives java.lang.Float.
BIP's (10.1.3.4.1) expectation was:
<element name="CF_CYCLE_COUNT" value=":PM_cycle_count" function=""/>
