Unable to import json simple's .jar file into JSP file

Question

I have copied the json-simple-1.1.1.jar into the WEB-INF/lib folder. In index.jsp, I am writing: <%@ page import="org.json.simple.parse.JSONParser" %>.

But this gives me the error:

An error occurred at line: 17 in the generated java file
Only a type can be imported. org.json.simple.parse.JSONParser resolves to a package

I have seen other questions with this error but they all point to pasting the jar file into the right folder. I've already done that. What am I missing? Is there something I need to write in the Catalina host config by any chance? The virtual host for this in server.xml is:

<Host name="test-jsp.dev" appBase="/var/lib/tomcat7/webapps/test-jsp.dev"></Host>

Maybe an XML attribute I'm not setting?

I have already restarted the server. Also double checked that the group/owner of the jar file is root, because that's the way it is in the webapps/ROOT folder.

Yes, `sudo service tomcat7 restart`. Problem did not resolve. — Aditya M P, May 02 '14 at 08:31
are u sure that json-simple-X.X.jar available in your application Lib folder — Naveen Ramawat, May 02 '14 at 08:32
Not an answer, but you should not use scriptlets in JSPs anyway. JSPs are view components, using the EL, the JSTL and other custom tags to generate HTML from a model prepared by a controller. The controller, written in Java, as a servlet (for example), should be where you parse your JSON. — JB Nizet, May 02 '14 at 08:33
Thanks @JBNizet, I'll keep that in mind for real world projects. Right now rushing for something ;) — Aditya M P, May 02 '14 at 08:35
@NaveenRamawat, do you mean in `WEB-INF/lib`? Yes. Is there any other folder? — Aditya M P, May 02 '14 at 08:35
You need to add ";" at the end of your import. Can you try <%@ page import="org.json.simple.parse.JSONParser;" %> — Hirak, May 02 '14 at 08:43
@MaVRoSCy I had downloaded the file a couple times and tried just in case, same thing happened. — Aditya M P, May 02 '14 at 09:50
@Hirak yes I saw that in another question and tried it out but didn't work :( — Aditya M P, May 02 '14 at 09:51
Could this be a file permission issue? I changed the group of the jar to tomcat7 and made sure all have read and execute permissions... no luck yet. — Aditya M P, May 02 '14 at 09:57
Do you find this class `JSONParser` located inside your jar . i mean the required package — Santhosh, May 02 '14 at 10:33
Yes, I used [Jar Explorer](https://code.google.com/p/jar-explorer/) to verify that the class [actually exists](http://imgur.com/51aw0mM). — Aditya M P, May 02 '14 at 10:49
