Josh,
Thanks! I took your WSDL and ran it through WSDL2Java
to generate the client java. To my surprise, the
echoAttachment signature was:
String echoAttachment( String ).
Given that the MIME type of the attachment is
"text/plain", it seemed that the attached file could
be considered a container for a long string. I then
changed the MIME type to "image/jpeg" and got this
signature:
java.awt.Image echoAttachment(java.awt.Image)
Then I changed the MIME type to "audio/x-wav" which is
what I have in original WSDL which won't compile --
and I got the same error message:
java.lang.NullPointerException
at
org.apache.axis.wsdl.toJava.Utils.getNewQName(Utils.java:613)
at
org.apache.axis.wsdl.toJava.JavaStubWriter.writeOperationMap(JavaStubWriter.java:384)
So it seems like a problem figuring out what sort of
object to convert "audio/x-wav" to.
I then changed the MIME type to
"application/octet-stream", but that failed with the
same error.
Is there any way to, say, map "audio/x-wav" to
javax.sound.sampled.Clip? Or at least to map
"application/octet-stream" to a DataHandler?
