Once a project is created in Eclipse Europa of a certain type, it’s not the most straight forward process of changing the project to a different type. For example you have a project that Eclipse considers to be a Java project, but it’s actually a Web Project, you don’t get to take advantage of all of the features available for Web Projects, such as deploying to a local tomcat server, unless Eclipse is aware that it’s a web project. This has to do with the project settings and what eclipse considers the “Nature” of the project.

I basically needed the update button to be the default action on clicking enter in the form, but there were multiple submit buttons in my form and they weren’t in the order I needed due to UI design. This was a quick and dirty solution to select an html submit button and make it the default when a user clicks enter from certain or all input elements on the form. It could be tweaked to give specific behavior to specific types of input boxes, such as invoking a tab on enter in between required elements, but the general idea is using jQuery to click the default button when the user hits enter.

Ran into some issues on some of our Java sites today and needed a quick fix to protect the sites from malicious Cross Site Scripting (XSS) attempts. If you’re not aware of what XSS is and have websites that have sensitive user data, you may want to read up, you’re probably vulnerable, which means your users are vulnerable. I’m not claiming this is a perfect solution, but it was easy to implement and corrected the vulnerabilities with form and url injection. We basically have a Servlet Filter that’s going to intercept every request sent to the web application and then we use an HttpServletRequestWrapper to wrap and override the getParameter methods and clean any potential script injection.
