Servlet Producing Wrong Output

[shaun michael]

When I access the code below from a command line program it gives me the correct output, however when I access the same code from a servlet the output is incorrect. For example when I run from the command line the variable name = "program" and link = "program.html" and the output would be <a href="program.html">program</a>. When accessed from a servlet the variables come out backwards so the output would be <a href="program">program.html</a>. Can someone explain why this happens and how it might be fixed. Thanks in advance.

Shaun,
Welcome to JavaRanch!

Accoring to the API, "The order of attributes in the list is unspecified, and will vary from implementation to implementation." My guess is that your servlet container is pointing to a different version/implementation of SAX than your command line.
