Problem with xs:base64Binary
Hello all,
I'm having a little trouble with a field whose type is xs:base64Binary. I
am looking for a way to populate the associated field in my Java code. Any
help/sample code would be greatly appreciated. Here are the details:
1) After the wsdl2java conversion, the xs:base64Binary field is represented
by a "javax.activation.DataHandler".
(see
http://java.sun.com/j2ee/1.4/docs/api/javax/activation/DataHandler.html)
2) The code examples that I found for DataHandler generally involve things
like files, etc. For example:
http://ws.apache.org/axis2/1_2/mtom-guide.html#21
(Note: It seems that the lines of code with OMText aren't complete).
3) In my case, my data is much simpler. For example, if I could populate
the field with a string (e.g. "0 23 532 12"), that would be sufficient.
My quick solution is to just change this field's type to xs:string. The
reason I'd like to keep it xs:base64binary is because it's someone else's
schema, so I wanted to stay faithful to their data types.
Thanks!

Yep... It can even be a byte[].. base64Binary data type stands for
base64 encoded binary data.. Hence everything that involves
Datahandlers work in binary(byte) level..

ouch... Please use the newest version.. It seems to be complete..

What's your exact use case.. What are you trying to send in that
field.. Do you already have a base64 encoded string with you??

Please find out what kind of data (semantics) is he expecting, whether
it's image or a signature etc... It's ok to change it to string.. But
you would need to make sure to set the content to a base64 encoded
string of the expected type..

Thilina

Hi,
I have similar requirement for develop a soap client that send base64binary.
My use case is that i got to convert some of the sensitive info from string
into base64binary, then send it as inline content instead of attachement.
Matt, do you found the solution of:
> // Insert miracle here, where myString data is sent
> // to the dataHandler object and turned into
> // base64 data.
Thilina, in your ByteArrayDataSource example, do I need to configure
somewhere for the base64binary?
Thank you.:-D
Truly,

First of all I wonder why do you want to send a plain string using
base64Binary.. Is it a huge string and do you want to send it as an
attachement?..
Use org.apache.axiom.attachments.ByteArrayDataSource..
String test = "test";
ByteArrayDataSource dataSource = new ByteArrayDataSource(test.getBytes());
DataHandler dataHandler = new DataHandler(dataSource);
Other way round,
InputStream inputStream = dataHandler.getInputStream();
Read the content to a byte[].. Create the string from that byte[]...

RE: Problem with xs:base64Binary
Posted by Matthew Fadoul <ma...@my3d.com>.
Thanks for the help, Thilina.
Here's a little clarification of my situation:
* I'm creating both the client and server side functionality from my WSDL,
so I don't really have to worry about someone else reading or writing to the
field.
* My use case is basically to use the xs:base64Binary field to pass a long
string that holds space-delimited integers ("0 23 532 12"). The field is
contained in some of my WSDL messages. Inside my server-side code, I'm
trying to create sample datasets which include the xs:base64Binary object.
Unfortunately, I'm not quite able to figure out how to use the DataHandler
class and DataSource interface.
So, the simplest code fragment to show what I'd like to do is:
public DataHandler convertStringToBase64Binary (String myString) {
// Example myString value = "0 23 532 12";
DataHandler myBase64BinaryField;
// Constructor for DataHandler...
// Insert miracle here, where myString data is sent
// to the dataHandler object and turned into
// base64 data.
return myBase64BinaryField;
}
It would be interesting to see the other direction (i.e. DataHandler to
String) as well.
* As I mentioned in my previous message, the easy solution is to just send
the data as an xs:string, which works for me since I'm creating both the
client- and the server-sides of the web service. That said, I am still
interested in understanding the mechanics of DataHandler.
Thanks again,
