Can I override the MimePartSerializer?? - Need Help Soon

[Vamsi Krishna]

hi All,

My service has a method - saveJPEG(String name, java.awt.Image img) taking a name and a jpeg image and saving that jpeg with that name in a specified directory.
I am using SOAP RPC. Since there is no Serializer/Deserializer for Image type, i created my ImageSerializerDeserializer. The DD specifies this info. The client also does the mapTypes with this info. What I do in this class is - in the marshall method, i take the Image source, convert it into a DataHandler object and call the MimePartSerializer with the DataHandler object (i simply pass all the other parameters onto MimePartSerializer - only the src is changed to dhsrc).
In the unmarshall method - i first call the MimePartSerializer.unmarshall method and get the Bean. Since i know it is Image, i convert the DataHandler value in this bean to an Image object and create and return that Image bean.

So the client works fine now - my ImageSerializer's marshall method gets called and the call goes through to the Server. The problem is in the Deserialization. My ImageSerializer class's unmarshall method is never called at the server end. Always the MimePartSerializer.unmarshall is called and I get a fault saying there is no such method that accepts a DataHandler - saveJPEG(java.lang.String,javax.activation.DataHandler).

What is the problem here? Is there a way to override the deserializer for javax.activation.DataHandler? Is my approach correct?
(I know i can have an overloaded method with this signature taking the data handler and in this method convert the dh to image and call my original method. But this is not what i am looking for.)


I appreciate any help in this.

thanks a lot in advance,
Vamsi.


The DD entry is -
