java - jetty package org.json.simple does not exist -

i have simple servlet used jetty.

this fragment of servlet:

import org.json.simple.jsonobject; import org.json.simple.jsonvalue;  public class oscar4servlet extends httpservlet {  ...      protected void dopost(httpservletrequest req, httpservletresponse resp)         throws servletexception, ioexception     {         request.setcharacterencoding("utf8");         response.setcharacterencoding("utf8");         response.setcontenttype("application/json");         printwriter out = resp.getwriter();          jsonobject obj = new jsonobject();         obj.put("message", "hello server");         out.print(obj);     } } 

after invoking:

javac -cp  /usr/share/jetty/lib/servlet-api-2.5.jar  oscar4servlet.java  

i'm getting error:

oscar4servlet.java:5: error: package org.json.simple not exist import org.json.simple.jsonobject;                       ^ oscar4servlet.java:6: error: package org.json.simple not exist import org.json.simple.jsonvalue; 

although have json-simple-1.1.1.jar (downloaded http://code.google.com/p/json-simple/downloads/detail?name=json-simple-1.1.1.jar) in web_inf/lib directory... ideas why?

when compiling need specify full compilation classpath. need modify command to:

javac -cp  /usr/share/jetty/lib/servlet-api-2.5.jar:<path-to>/json-simple-1.1.1.jar oscar4servlet.java  

(and of course other dependencies)

alternatively, if dependencies in /some-path/web-inf/lib can do:

javac -cp  /usr/share/jetty/lib/servlet-api-2.5.jar:/some-path/web-inf/lib/* oscar4servlet.java
