How to debug Perl apps with Eclipse Debugging


How to debug Perl apps with Eclipse
Debugging Perl applications can be a frustrating process. Many Perl programmers rely on print statements and so-called "postmortem debugging." Others use the built-in Perl debugger. Neither provides a coherent execution environment for monitoring the execution of a script, and neither supports the debugging of a Common Gateway Interface (CGI) script during execution. In this tutorial, we will look at the debugging functionality offered by the Eclipse Perl Integration (EPIC) plug-in for Eclipse, which offers a rich debugging environment available and integrated with the EPIC Perl development environment.

PHP has been a popular scripting language for some time. However, with the growing buzz over Java technology and Apache Geronimo, a J2EE-certified application server, many experienced developers shy away from using PHP with Geronimo, because only JavaServer Pages (JSP) is supported out of the box. The PHP Java Bridge solves this problem by providing full support for PHP on Geronimo and for sharing sessions across both PHP and JSP scripts.
