java.lang.ClassNotFoundException : What have I missed here?
Hello,
I'm developing Tomcat apps using Eclipse with the Tomcat plugin. I
thought I layed out my directory structure correctly but Tomcat is
still failing to locate my Java class. Here's my setup.
Java src file location:
C:\eclipse\workspace\Nuthin\WEB-INF\src\com\visualio\business\NuthinClass.java
Java src file:
package com.visualio.business;
import java.io.*;
import javax.servlet.http.*;
import javax.servlet.*;
public class NuthinClass extends HttpServlet {
public void doGet (HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
PrintWriter out = res.getWriter();
out.println(Nuthin from nuthin leaves nuthin ...);
out.close();
}
}
Java class location:
C:\eclipse\workspace\Nuthin\WEB-INF\classes\com\visualio\business\NuthinClass.class
My web.xml file:
?xml version=1.0 encoding=UTF-8?
!DOCTYPE web-app PUBLIC -//Sun Microsystems, Inc.//DTD Web
Application 2.3//EN http://java.sun.com/dtd/web-app_2_3.dtd;

servlet-classNuthinClass/servlet-class

servlet-mapping
servlet-namenuthin/servlet-name
url-pattern/nuthin/url-pattern
/servlet-mapping
/web-app
Relevant Tomcat config file location:
C:\Program Files\Apache Software Foundation\Tomcat
5.5\conf\Catalina\localhost\Nuthin.xml
Relevant Tomcat config file contents:
Context path=/Nuthin reloadable=true
docBase=C:\eclipse\workspace\Nuthin
workDir=C:\eclipse\workspace\Nuthin\work /
When I try and run http://localhost:8080/Nuthin/nuthin I get:
exception

Can someone please clarify what I missed in my configuration?

your web.xml needs to have
servlet
servlet-namenuthin/servlet-name
servlet-classcom.visualio.business.NuthinClass/servlet-class
/servlet
instead of just the class name.

Strange WAR file creation error
Hello, I am trying to create a WAR file of the following directoy: duglaDataModel/ duglaDataModel/DataController.as duglaDataModel/duglaDataModel.mxml duglaDataModel/Employee.as duglaDataModel/employees.xml duglaDataModel/locations.xml duglaDataModel/WEB-INF/ duglaDataModel/WEB-INF/classes/ duglaDataModel/WEB-INF/web.xml So I cd to duglaDataModel and type: jar cvf c:\downloads\duglaDataModel .war . But this fails with and exception: added manifest adding: DataController.as(in = 958) (out= 452)(deflated 52%) adding: duglaDataModel.mxml(in = 2378) (out= 637)(deflated 73%) adding: Employee.as(in = 391) (out= 210)(deflated 46%) adding: employees.xml(in = 468) (out= 154)(deflated 67%) adding: locations.xml(in = 225) (out= 80)(deflated 64%) adding: WEB-INF/(in = 0) (out= 0)(stored 0%) adding: WEB-INF/classes/(in = 0) (out= 0)(stored 0%) adding: WEB-INF/web.xmljava.util.zip.ZipException: attempt to write past end of STORED entry at java.util.zip.ZipOutputStream.write(ZipOutputStream.java:264) at sun.tools.jar.Main.addFile(Main.java:614) at sun.tools.jar.Main.create(Main.java:412) at sun.tools.jar.Main.run(Main.java:142) at sun.tools.jar.Main.main(Main.java:903) Why? Note, as far as I can tell the directory is just fine since I can copy it into webapps and the application works. I just can't WAR'ize the directory. Any ideas?
