Hi all,

I am trying to compile a servlet, and am getting the following error.

C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\flatironswp1\WEB-INF\classes>javac export\ExportUtil.java
export\ExportUtil.java:5: package javax.servlet.http does not exist
import javax.servlet.http.*;
^

and here's my code:

package export;

import java.io.*;

import javax.servlet.http.*;
import javax.servlet.*;

public class ExportUtil extends HttpServlet {
  public void doGet (HttpServletRequest req,
                     HttpServletResponse res)
    throws ServletException, IOException
  {
    PrintWriter out = res.getWriter();

    out.println("blah, blah...!");
    out.close();
  }
}

Do I need any jars or something in my classpath? please suggest.


Thanks.

Yes, those components are not part of the Java SE API so you will need to provide classpath entries to the locations of the jars containing the Java EE api implementations. There should be some info in your Tomcat docs on how to compile those source files.

You oviously missed this part of forum

When posting programming code, encase it in (code), (code=syntax), where 'syntax' is any language found within our Code Snippets section, or (icode), for inline code, bbcode tags. Also, to keep DaniWeb a student-friendly place to learn, don't expect quick solutions to your homework.

Plus error messages that you getting would be helpful instead of us going through your coding and trying to eliminate various mistakes you made

In Eclipse: Project -> Properties -> Java Build Path -> add Libraries
Click on "Add Library" and select Server Runtime (I am using Geronimo 2.0)
