Useful Java syntaxes.

org.apache.commons.lang3.Validate

This class assists in validating arguments. The validation methods are based along the following principles:

An invalid null argument causes a NullPointerException.
A non-null argument causes an IllegalArgumentException.
An invalid index into an array/collection/map/string causes an IndexOutOfBoundsException

Pretty printing SOAP messages. (60 of 285 technotes for 2015)

Handy Java code to print SOAPMessages

References: - http://bit.ly/1dkVWoW

public static String getSOAPMessageAsString(SOAPMessage soapMessage) {
      try {

         TransformerFactory tff = TransformerFactory.newInstance();
         Transformer tf = tff.newTransformer();

         // Set formatting
        
         tf.setOutputProperty(OutputKeys.INDENT, "yes");
         tf.setOutputProperty("{http://xml.apache.org/xslt}indent-amount",
               "2");
         
         Source sc = soapMessage.getSOAPPart().getContent();

         ByteArrayOutputStream streamOut = new ByteArrayOutputStream();
         StreamResult result = new StreamResult(streamOut);
         tf.transform(sc, result);

         String strMessage = streamOut.toString();
         return strMessage;
      } catch (Exception e) {
         System.out.println("Exception in getSOAPMessageAsString "
               + e.getMessage());
         return null;
      }

   }
