I am consuming a web service, not providing one. I have reached the point where I have the whole thing working, but it only works once through a ColdFusion "createObject" invokation.

Still need help. System: Windows Server 2003 with ColdFusion 9 single server installation.

I used Apache's wss4J library and wrote a simple Java class as the entry point. The custom Java class simply takes the complete SOAP message as a String argument, passes the String to the wss4j DateStamp class, then passes the resulting SOAP parts object to the signature class, then the encryption class. It then returns the signed and encrypted SOAP envelope, which has been converted from a document (SOAP parts) to a String by the PrettyDocumentToString function.

All of this works and I get a SOAP envelope with security header and signed, encrypted body. The problem is that, after restarting the ColdFusion service (single server install on Windows Server 2003), it all works one time, but subsequent runs result in an error occurring within the wss4j signature code. I have even used Winmerge to compare the entire ColdFusion9 directory immediately after restart, immediately after the 1st run, and immediately after the 2nd run. The only differences were in the log files. There were differences in the ColdFusion9\lib\neo-datasource.xml file, but only in the order of a couple of datasource descriptors, not the content.

Below is the code and stack trace:

ColdFusion calling script:

<cfscript>
   variables.fileContent = FileRead(getDirectoryFromPath(getCurrentTemplatePath()) &

                                                  "ASI_source_request_example.xml");

   variables.encSOAP=createobject("java","ProcessIDSRSSOAP").runProcess(fileContent);

   writeOutput("<br><br>encSOAP: <br>");
   writeOutput("<code>#variables.encSOAP#</code>");
   writeDump(var="#variables.encSOAP#", format="html", output="#expandPath('./')#_DUMP-OUTPUT.htm");
</cfscript>

Obviously, something is missing from org.apache.ws.security.message.DOMCallbackLookup.getElements.
The code feeding it is:

return callbackLookup.getElements(part.getName(),part.getNamespace());

I can't seem to figure out why it works the first time when called from CF, but fails with this error on subsequent runs.
