Subject [jira] Created: (AXIS2-495) ADB base64Binary handling
Date Wed, 15 Mar 2006 23:50:58 GMT
ADB base64Binary handling

         Key: AXIS2-495
     Project: Apache Axis 2.0 (Axis2)
        Type: Improvement
  Components: databinding  
    Reporter: Thilina Gunarathne
 Assigned to: Ajith Harshana Ranabahu 

I noticed that the code generated from ADB converts binary data back and forth in the case
of Base64Binary schema type MTOM optimised contents.. AFA i understood this behaviour leads
Axis2 to read the Binary data in MIME parts and converts them to Base64binary and then once
again converts that Base64String to bytes... 
This behaviour is inefficient, can lead to serious memory issues and this will be a limiting
factor for code generated services to handle large binary attachments....  
IMHO use of DataHandlers directly rather than encoding/re encoding binary back and forth is
the correct way to go.. This is what we are doing in the OMTextImpl... In that case if data
came as an attachment, then it won't undergo any conversions.. If they came in line as Base64
then they will decode to binary... 
We can either change the object.get/setData methods to use DataHandlers instead of byte[].
Or we can keep them as it is by getting and setting byte[] internally to data handler...
