Going Modern

A large percentage of outsourced, onshore and offshore resources, are skilled in XML, Java and other Internet-based languages and development techniques, meaning their ability to tinker with and add features to 3GL/4GL applications is limited at best and that cost savings of such as model is neutralized. Adding to the conversation is the acknowledgment that more than 200 million lines of COBOL code are currently in use while another five million are being written each year. This presents a challenge given the waning number of students studying computer science and the shrinking number of experts in legacy applications.

According to Gartner, “interviews conducted with IT sourcing managers across the Gartner client base hint at what’s to come: Many have seen price hikes of 10% to 15% in certain skills during the past year.” (more…)

While working on an application for a client, I encountered some issues with Java’s MessageFormat. In particular, I needed to pass MessageFormat a string that contained single-quotes and curly braces that would be treated literally. This is an issue, because single-quotes and curly braces are special characters in MessageFormat land.

MessageFormat is designed to allow you to dynamically create a string based on a static pattern and a set of inputs. For example, this is from the MessageFormat JavaDoc:

 Object[] testArgs = {new Long(3), "MyDisk"};

 MessageFormat form = new MessageFormat(
     "The disk \"{1}\" contains {0} file(s).");

 System.out.println(form.format(testArgs));

 // output, with different testArgs
 output: The disk "MyDisk" contains 0 file(s).
 output: The disk "MyDisk" contains 1 file(s).
 output: The disk "MyDisk" contains 1,273 file(s).
