This is a very popular framework for building java based applications, and if you choose to build a web application with the framework it comes with an embedded version of tomcat,or jetty , or undertow within it. Its very simple...

Re: Failed to connect Internet with Proxy setting

Hi Sam, just some questions I have: 1) Can you start up a web-browser and try to get on to the internet, using the university proxy settings. (For example in Firefox Set the proxy settings in Tools->Options->Network-Settings) . Does this work for you ? Can you get to google ? 2) Do you know what typ...

Re: Please help robotic arm project

Hello, Just wondering , how do you run your program ? It appears that it needs root permissions. Perhaps you could try running your program with the sudo command in front of it . So your command line might look like sudo python myProgram.py sudo runs the program with root permissions. I hope this he...

Re: using pi4j inside JSP fails

Hello, I cannot seem to access any resources at that link which you posted. The point made by Douglas6 (the one dated Tue Sep 16, 2014 1:34 pm) , I think is actually correct. I think that you may have the lib directory in the wrong place. Your tomcat structure should look like this: + webapps (this ...

Re: using pi4j inside JSP fails

Hello, that's weird. It should at least find the class if the jar files are where you say they are. Just for information, what version of the jvm are you using (I assume its 1.7 ?)

Re: Installing Tomcat

Hi,

yes, you can install Tomcat without Apache web server.

You can even have it that your Tomcat instance itself runs on port 80.

Tomcat is primarily designed for dynamic pages (jsp's etc) but can also serve out static content as well.

Re: Installing Tomcat

Yes, you wont have any conflicts with Tomcat and Apache. Tomcat _normally_ will listen on port 8080 for any requests, and as mentioned in the previous post you can use Apache to pass off any requests on the normal port 80 to this port for your dynamic pages. This can be done using mod_proxy or , you...
