Updated about every week.
OK, I have been trying for two days to get the "Building and Running a Web
Application" to work. I found the bug for the / in the
req.getRequestDispatcher("showBrowser.jsp").forward(req,resp);
but all that did was get me a java.lang.StackOverflowError by just running
javax.servlet.http.HttpServlet.service(HttpServlet.java:689)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
org.eclipse.wtp.tutorial.SnoopServlet.doGet(SnoopServlet.jav a:23)
javax.servlet.http.HttpServlet.service(HttpServlet.java:689)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
org.eclipse.wtp.tutorial.SnoopServlet.doGet(SnoopServlet.jav a:23)
javax.servlet.http.HttpServlet.service(HttpServlet.java:689)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
repeatedly..
I copied the code from the tutorial and use
http://localhost:8080/tutorial/snoop/* when I run it from Run From -->
Run from server. I am using jdk1.4.3... and have tried it on both tomcat
5.0 & 5.5 to no avail.
Any help would be appreciated.
Thanks
Calvin

I decided to try another example, the SchoolSchedule. I can get the
Schedule.jsp to run if I add Schedule.jsp to the end of the
http://localhost:8080/SchoolSchedule/ which is all that appears in the
link window when I choose Run on Server. When I try to add a class with
the button on the window, I get:
HTTP Status 404 - /SchoolSchedule/Schedule
------------------------------------------------------------ --------------------
type Status report
message /SchoolSchedule/Schedule
description The requested resource (/SchoolSchedule/Schedule) is not
available.
------------------------------------------------------------ --------------------
Apache Tomcat/5.5.17
When I move my code to the webapps directory of Tomcat, the initial window
opens but when I try and add a class I get:
type Exception report
message
description The server encountered an internal error () that prevented it
from fulfilling this request.
exception
java.lang.IllegalArgumentException: setAttribute: Non-serializable
attribute
org.apache.catalina.session.StandardSession.setAttribute(Sta ndardSession.java:1251)
org.apache.catalina.session.StandardSessionFacade.setAttribu te(StandardSessionFacade.java:129)
org.eclipse.wtp.sample.classschedule.ScheduleServlet.doPost( ScheduleServlet.java:78)
javax.servlet.http.HttpServlet.service(HttpServlet.java:709)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
note The full stack trace of the root cause is available in the Apache
Tomcat/5.5.17 logs.
Thanks

How I managed to get the project to work:
Create new project:
Web --> Dynamic Web Project
Next
Name --> SchoolSchedule
Target runtime --> Apache Tomcat 5.5
(Then finish off remainder of screens using defaults)
Switch to J2EE perspective (Not sure why but I clicked OK)
Files:
Put the .java files in the src folder
Put the Schedule.jsp in the WebContents folder
The .class files will automatically be placed in the build folder
Put the jstl.jar and standard.jar int WEB-INF --> lib folder
All .java files must implement Serializable and have a serialVersionUID
The web.xml file is automatically built and has stuff in it for XDoclet
and I have no idea what that does yet.
Issues still to resolve:
When I run the code using Run AS --> Run on servier or export a .war file
and publish it to my webapps folder I still have to add the /Schedule.jsp
after the http://localhost:8080/SchoolSchedule/

Thanks Gabor Matyi
