Send XML file as attachment using Email activity in SOA / BPEL 11g

Steps are:

1. Create a BPEL project. 

2. Modify input schema element 'process' to have 'To' and 'AttachmentBody' as string type elements. 

3. Insert a Email Activity inside BPEL.

4. Double Click on the Email activity and set / pass values to required fields. 

5. Create a Temp variable say 'EncodedTemp' and copy 'AttachmentBody' to the EncodedTemp' using assign activity.

6. Insert a JavaEmbedding Activity which will encode the contents of 'EncodedTemp' to Base64Encoding. Below is the code which is used - 

try { String temp1 = (String)getVariableData("EncodedTemp"); String temp2 = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>"; String temp = temp2.concat(temp1); oracle.soa.common.util.Base64Encoder Encoder = new oracle.soa.common.util.Base64Encoder(); java.lang.String Temp = null; Temp = Encoder.encode(temp); setVariableData("EncodedTemp",Temp); } catch(Exception e) { System.out.println(e); }

        Note: 

          To use Java Embedding you also need to import oracle.soa.common.util inside BPEL.

          Go to BPEL Source and paste import statements above Java Embedding activity -

<bpelx:exec name="import" language="java" version="1.5" import="oracle.soa.common.util.*"/> <bpelx:exec name="import" language="java" version="1.5" import="java.io.*"/>

7. Now Double click on Email activity again and click on Attachments. Set the values as shown below - 

Deploy the project and test it.
