Re: special characters from payload

Hi Mahesh,

use a java mapping to remove special characters. below code will replace all the special characters you provide in the check string array with a null value.

public class REPLACESC implements StreamTransformation {

private AbstractTrace trace = null;

private Map param = null;
String  inputFileName;

public void setParameter(Map param) {
  this.param = param;
  if (param == null) {
   this.param = new HashMap();
  }
}
   

     public void execute(InputStream in, OutputStream out)
               throws StreamTransformationException {
      trace = (AbstractTrace) param.get(StreamTransformationConstants.MAPPING_TRACE);
   trace.addWarning("JAVA Mapping Start");
  
   /*this block of code will remove all the not allowed special characters from outbound xml*/
          try
          {
               byte b[]=new byte[in.available()];
               String encoding="UTF-8";
               in.read(b);
               String inputXML=new String(b);
                
              
        
               String[] check = { "]", "&", "<", ">", """, ",", "#", "\\$", "@", "\\[", "\\)"};
               for (int i = 0; i < check.length; i++) {
             inputXML=inputXML.replaceAll(check[i],"");
               }
               out.write(inputXML.getBytes(encoding));
          }    
          catch(Exception e)
          {
               throw new StreamTransformationException(e.getCause().toString());
          }  
         
        
     }
   

     public void transform(TransformationInput arg0, TransformationOutput arg1)
               throws StreamTransformationException {
      this.execute(arg0.getInputPayload().getInputStream(), arg1.getOutputPayload().getOutputStream());
         
     }
}

you can also use an excel file to store special characters and do a file lookup if the number of special characters are not fixed. let me know if you want to use this option , i will share the code.
