Hi, for several weeks, I have been using the encoding type : String encodingStyleURI = Constants.NS_URI_LITERAL_XML; to invoke a remote method via SOAP, capable of manipulating DOM Elements ..... but now, I'd like to pass, as parameter of the method, a vector of DOM Elements ..... but, it can't because of the problem of serializing .....: [SOAPException: faultCode=SOAP-ENV:Client; msg=I only know how to serialize an 'org.w3c.dom.Element'.; targetException=java.lang.IllegalArgumentException: I only know how to serialize an 'org.w3c.dom.Element'.] I never know which type of "encodingStyleURI" to use in order to invoke a method .... Can anybody help me, and give me a list and explanations about these types of encoding .... thank you !!
