A url such as /index.php/my-page-name doesn't seem to ever hit the PHP servlet . It gets a browser error that request resource is not available.

Good evening, I am in the process of writing a Java Servlet (Struts 2, Tomcat, JSP etc) which is capable of doing some fairly complex simulations. These can take up to 2 minutes to complete on the and will return a graph of the results. It is trivial to calculate the percentage of the simulation completed because the process works by re...
I'm using Tomcat as a servlet container, and have many WARs deployed. Many of the WARs share common base classes, which are replicated in each context due to the different classloaders, etc. How can I ensure resource cleanup on context destruction, without hooking each and every web.xml file to add context listeners? Ideally, I'd like...

I'm having trouble testing a web app with Safari. My app returns wave audio data. The problem happens when I change the application and hit it again from Safari. Safari caches the original response so no matter how many times I hit refresh it seems like I've not updated anything. I can almost get around this using force refresh with Fire...

I need to create a form that will allow, among other things, a user to upload an unknown number of files to the server running Tomcat. It would be nice if the form could add upload slots to the form as needed. I haven't found much useful on the subject, so I thought I would poll the community. ...

Is there a way (without buffering the whole Inputstream) to take the HttpServletRequest from a Java Servlet and write it out to a file using all NIO? Is it even worth trying? Will it be any faster reading from a normal java.io stream and writing to a java.nio Channel or do they both really need to be pure NIO to see a benefit? Thanks....
