How to zip and encode a field as base64 with a UDF in a Message Mapping

[xavisanse]

It's possible that in some scenarios you should compress  as a ZIP and send a document through  a WebService in base64. For achieve this we can use UDF and some libraries.

The UDF will be this:

public String invoice2zip(String invoice, String filename, Container container) throws StreamTransformationException{

ByteArrayOutputStream baos = new ByteArrayOutputStream();

ZipOutputStream zos = new ZipOutputStream(baos); 

 BASE64Encoder encoder = new BASE64Encoder();

String encoded = "";

try{

     zos.putNextEntry(new ZipEntry(filename)); 

    zos.write(invoice.getBytes());

     zos.close();

      encoded = encoder.encode( baos.toByteArray());

}catch(Exception e){

return "";

}

     return encoded;

}

We need to import a library for Base64 encoding:  sun.misc.BASE64Encoder
