I am using Tomcat 5.5.15. When I run a servlet, it always gives the following error message.

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

javax.servlet.ServletException: Cannot allocate servlet instance for path /servlet/Training
org.apache.catalina.servlets.InvokerServlet.serveRequest(InvokerServlet.java:388)
org.apache.catalina.servlets.InvokerServlet.doPost(InvokerServlet.java:169)
javax.servlet.http.HttpServlet.service(HttpServlet.java:709)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

1.Yes, your servlet path is wrong

2.The name of the servlet in the file is different from then what you have saved

as a file

@hcarouselauthorJun 21.2006 — Thanks for reply, Khalid. The following is what I wrote in the web.xml file.

<servlet>
<servlet-name>Training</servlet-name>
<servlet-class>Training.Training</servlet-class>
</servlet>

I put Training.class under /webapps/ROOT/WEB-INF/classes/Training

Is it the correct path? By the way, I am using UNIX.

Success!
