Converting the Opaque Element into Readable format.

Question

Hi,
Right now, I am using the FTP adapter to continously poll for a new file. Whenever new file comes in, our BPEL process gets initiated. We get the contents of the file in the variable of opaque element( I have given Message Schema is Opaque in the FTP Adapter configuration).
I have to send the content of the file as the attachment in the e-mail. So when I am using the above variable in the e-mail notification, I am getting the data in the non-readable format, since the corresponding variable is of opaque schema. Now my requirement is to convert this non-readable opaque data into the readable data.
Any help is highly appreciatable.

Sorry the code I gave you was decodeing a hex variable into string.
Try this code:
String input = (String)getVariableData("InputBinary");
Base64Decoder Decoder = new Base64Decoder();
String decoded = Base64Decoder.decode(input);
setVariableData("OutputString",decoded);
you will also need to add the java class:
<bpelx:exec import="com.collaxa.common.util.Base64Decoder"/>
Just looking at the Base64 string you are testing. It is missing the 'g' off 'Testing'. The correct binary string should be VGVzdGluZw==
I'm not sure how this code is getting generated but you may need to look in that.
If you want the code to encode into binary use this:
String input = (String)getVariableData("InputString");
Base64Encoder encoder = new Base64Encoder();
byte[] barray = (new String(input)).getBytes();
BigInteger bint = new BigInteger(barray);
String encoded = Base64Encoder.encode(barray);
setVariableData("OutputBinary",encoded);
add the java class:
<bpelx:exec import="com.collaxa.common.util.Base64Encoder"/>
sorry for putting you wrong.
cheers
