directory structure in tomcat

Question

hi I am having a project that runs perfectly over Netbeans without any problem in the syntax or connectivity bUt wHen i try to run the same jsp pages in tomcat it generates error. It is possible that the error is in the directory structure .

I had placed the jsp pages,html pages, css, images folder,web-inf folder and the .js files all in one folder in the webapps\login. When I run the index.html page it runs bUt when I click on the login page link it shows the following exception.

Can someone help me out?

HTTP Status 500 - message description The server encountered an internal error () that prevented it from fulfilling this request.

exception:

Try moving the WEB-INF folder to webapps/. I do not know if it is possible to have it in a webapps subfolder, but this is where it is usally located. — f_puras, Aug 30 '12 at 07:45
@f_puras: a `WEB-INF` folders inside `webapps` will create a new context with the name `WEB-INF`. This is definitely not what he wants. Usually, the `WEB-INF` is located within the context directory (e.g. `webapps//WEB-INF`) — tbl, Aug 30 '12 at 07:52
@tbk: Oh, right! I was thinking of the directory structure in an Eclipse project. When deployed, the OP's settings sound sensible. — f_puras, Aug 30 '12 at 08:02

It seems that com.mysql.jdbc.Driver is not int your in your classpath. You have to add all the needed jars (in this case this should be mysql-connector-java.jar, but there should be more) to:

webapps/app-name/WEB-INF/lib/

where app-name in your case is login.

Usually you would generate a WAR (web archive) file that contains your code base as well as all dependendent libraries and deploy that into tomcat (e.g. by copying into the webapp folder). ~~From what I remember,~~ NB generates the WAR file already (stackoverflow: How can I create a war file of my project in NetBeans?) and stores it in the dist/ folder of your project. Check if you can find a file that is called <projectname>.war inside that folder and copy it to your webapp directory.

ys m having that war file where to place that ?directly in the webapps directory or inside the login folder webapps\login\login.war – user1635172 Aug 30 '12 at 07:41
Put it directly into `webapps` folder, but move your existing `login` folder out of the way first, tomcat will most likely create a new one. – tbl Aug 30 '12 at 07:49
ys its working bt nw the format for the jsp pages is completely scattered – user1635172 Aug 30 '12 at 08:23
Scattered? That sounds like a different problem to me. Feel free to ask another question. – tbl Aug 30 '12 at 08:25
