Problem in localhost

Question

I have a problem when I run the web application project.

It gives me the following error:

The error occurs with Web Application Projects and Web Site Projects.

I tried the following URL, but it gives me the same error: http://localhost:3306/mobileApplication

This to enter the database:

http://localhost:3306/TheLostNumberApplication/
http://localhost:3306/TheLostNumberApplication/faces/welcomeJSF.jsp

It looks like the localhost doesn't run and I use MySQL and I don't know where can I find the localhost to run it.

What could be the matter?

Update:

I tried several solutions, but it still has the same problem (localhost doesn't run) ...

I want to ask now I have an Apache service. Should I have the Apache Tomcat, not the Apache service? Or doesn't it matter?

Answer 1

Do you have a firewall that could be blocking this?

Answer 2

Have you installed a web server on your machine yet?

here is one to get you up and running.

Edit:

it appears you are doing some JSP work, have you looked into Tomcat?

Answer 3

MySQL, which by default runs on port 3306, does not provide a web front-end. You will need to find out what port is opened by the webserver you're running. Typically, they run on port 80, port 8080, or port 8000.

Answer 4

What are you using as your Java Application Server? You need to start it first.

You'll find it under Administrative Tools -> Services in Windows.

Answer 5

Go into Internet Explorer Tools, click on the advanced tab, and in the settings tree, under the browsing branch, make sure that the setting "Show friendly HTTP error messages" is turned off.

This itself, won't solve your problem, but often Internet Explorer hides the truth from you when your web application is not executing properly. When you refresh, it will tell you what really went wrong (it might be a 404) but at least Internet Explorer won't be making assumptions about why the page failed.

I have had this myself, Internet Explorer reporting a 404 error, when in actuality, it was a syntaxical problem which was reported when this option was off. Turn it off and either update your question accordingly, or fix the problem. If this doesn't work, refer back to the other answers here.

Answer 6

if you're on a newer Windows then check your hosts file - microsoft removed the localhost entry in Vista(?). This can make life confusing when your dns refuses to resolve it.

check %windir%\System32\drivers\etc\hosts
