Re: [Laszlo-dev] SOAPElement class implementation

[Benjamin Shine]

It looks to me like SOAPElement is imported from  
javax.xml.soap.SOAPElement:

$ grep SOAPElement `find . -name "SOAP*.java"`
...
./WEB-INF/lps/server/src/org/openlaszlo/remote/swf/soap/encoding/ 
SOAPDataEncoder.java:
import javax.xml.soap.SOAPElement;
...

So that implementation must come from one of the jars we ship with,  
but I don't know which one.

Is this the information you were looking for?
