Web and Database Development Environment JSP Example
Please go through the HTML Example before doing this example.
NOTE: if you do not have a tomcat6 or tomcat7 directory, your account has NOT been configured for jsp and this tutorial will not be applicable.
Create a sample jsp file
JSP files can ONLY go in the tomcat6 or tomcat7 sub-directory of your web development directory.
- Go to the tomcat7 sub-directory of your web development directory and list the contents of the directory:
[username@l-lnx101 username]$ cd /webdev/user/username/tomcat7
[username@l-lnx101 tomcat7]$ ls
auth.jsp login.jsp QueryServlet_psql.html
EmpQuery.jsp protectedPage.jsp receivingPage.jsp
EmpQuery_psql.jsp QueryJSP.html sample.html
HelloWorld.jsp QueryJSP_psql.html sendingPage.jsp
index.jsp QueryJSP_psql.jsp validateLogin.jsp
JdbcQuery.jsp QueryServlet.html WEB-INF
- There are numerous examples here for you to look at and modify. If you go to http://webdev.cs.uiowa.edu/username-tomcat7/ it will load index.jsp by default.
- How do I compile my servlets so they will run?
You need to have the servlet-api.jar file in your classpath. You may also need the jdbc driver as well if you are doing database work. The servlet-api.jar file is in /var/tomcat/apache-tomcat-7/lib/servlet-api.jar. The file mysql-connector-java-5.1.7-bin.jar is in the same directory.
- I tried to go to http://webdev.cs.uiowa.edu/~username/tomcat7/ and I got a Forbidden message.
You need to go to http://webdev.cs.uiowa.edu/username-tomcat7/ to access jsp/servlet files.
- What's the difference between the tomcat6 and tomcat7 directories?
The files in tomcat6 are served by an instance of the Tomcat 6 servlet container. The files in tomcat7 are served by an instance of the Tomcat 7 servlet container.
