[Laszlo-dev] SOAPElement class implementation

[keiji Ono]

Hi Ben,

Thank you for your reply.
Yes, i also found your point and i was searching the implementation.
If it did not implement in OpenLaszlo source, it must came from saaj.jar 
or other jars.
As far as i know, this class declared as Interface class in SAAJ, so i 
wondered
where did it implement.
In your opinion, OpenLaszlo depend on the standard of JARs, right?
If so, i would appreciate it if you gave me the information about JARs 
version and so on.

Best,
Keiji Ono
