RE: Implicit objects in JSP pages
After looking at the generated Java file, I find that the request object is available because it's a parameter to _jspService(). I was attempting to instantiate my objects via calls to request.getAttribute() at the point of declaration, not in the first real code block in the page. Once I moved the instancing to the first code block, everything was fine. (Some aspects of JSP development are counter-intuitive to me, I'm afraid.)

Implicit objects in JSP pages
According to what I've read, there should be a javax.servlet.http.HttpServletRequest instance by the name of request available to me in my JSP at compile time without my having to do something special to obtain it, yet Jasper is insisting that no such object is available.

JSP path relative to servlet?
Now that I've got my servlet's XML parsing largely debugged, it's time to see some output. The problem is this (mucho code removed): String target = /MySeatMap/seatmap.jsp; . . . rd = getServletContext().getRequestDispatcher(target); rd.forward(request,response); I get 404'd, with the error that the JSP file can't be located. What am I doing wrong? (rd is declared, I just left that out.) jbm! -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]
RE: JSP path relative to servlet?
Cool...I'll check that ASAP.

If MySeatMap is your Context root, then you do not need to include that. String target = /seatmap.jsp; rd = getServletContext().getRequestDispatcher(target); should suffice.

Getting a servlet running under Tomcat-Apache 4.0.3
Greetings, y'all. * I've read all the documentation I can find. * I've emulated all the examples. * I've asked people I know who have set up servlets before. I still can't get access to the servlet I just wrote and installed. No matter how I've set up servlet-mappings, or url-patterns, or otherwise, I get 404'd on any attempt to test the servlet. The class files are where they're supposed to be, and the manager HTML applet says that the servlet is loaded and running. Supposedly (based on reading docs and looking at examples) servlet servlet-nameMySeatingServlet/servlet-name servlet-classSeating/servlet-class /servlet servlet-mapping servlet-nameMySeatingServlet/servlet-name url-pattern/seating/url-pattern /servlet-mapping in my web.xml file should be sufficient to get the servlet mapped to a url, but http://localhost:8080/seating produces nothing but a 404, specifically type Status report message /seating description The requested resource (/seating) is not available. Obviously I'm either misinterpreting the documentation, missed something somewhere, or making a bad assumption. I'd appreciate any input I could get on this, because the servlet customer is breathing down my neck for the prototype, which I would like to test before delivering it jbm! -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]
RE: Getting a servlet running under Tomcat-Apache 4.0.3
Fabian: something not directly mentioned in the howtos for deploying a servlet: you have to update the TOMCAT_HOME/conf/server.xml file for installing your application in the web-app-directory. You have to add an entry like Context path=/seating docBase=seating debug=0 reloadable=true/ in server.xml if you have your servlet in a folder named TOMCAT_HOME/web-app/seating/WEB-INF/classes That was the first thing I did, actually. No variations on that theme seem to be making any difference, and it doesn't matter whether it's under the Tomcat-Standalone or Tomcat-Apache section Jeff: Under what context path is your servlet deployed? The context path is typically the name of the directory under $TOMCAT_HOME/webapps in which your app resides. It's deployed where the examples are, and where the manager is. The specific path is drive:\Tomcat\webapps\MySeatMap\ with the class files in drive:\Tomcat\webapps\MySeatMap\WEB-INF\classes I've tried permuting this almost to exhaustion. I've been reading the example setups, and I can't even figure out how the HelloWorldExample class gets called. Something to do with filter tags, but I can't make out what's happening. And to repeat: I know the servlet is running, because the manager and the logs confirm it. For grins and giggles, here's the web.xml file. ?xml version=1.0 encoding=ISO-8859-1? !DOCTYPE web-app PUBLIC -//Sun Microsystems, Inc.//DTD Web Application 2.3//EN http://java.sun.com/dtd/web-app_2_3.dtd; web-app servlet servlet-name MySeatMap /servlet-name servlet-class /MySeatMap /servlet-class /servlet servlet-mapping servlet-name MySeatMap /servlet-name url-pattern /seating /url-pattern /servlet-mapping servlet-mapping servlet-name MySeatMap /servlet-name url-pattern /seating/ /url-pattern /servlet-mapping servlet-mapping servlet-name MySeatMap /servlet-name url-pattern*.map/url-pattern /servlet-mapping /web-app And the context entry: Context path=/MySeatMap docBase=MySeatMap isReloadable=true debug=2 crossContent=true/ Anyone see anything (in)obviously wrong? jbm! -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]
RE: Getting a servlet running under Tomcat-Apache 4.0.3
Jeff: The path listed in the manager is /MySeatMap. http://localhost:8080/MySeatMap/seating works. Amazing. :) Got a big list of errors to resolve, which is what I was looking for. Thanks! (Off for the rest of the day...see y'all in the AM) jbm! -Original Message- From: Jeff Larsen [mailto:[EMAIL PROTECTED]] Sent: Wednesday, April 10, 2002 12:14 PM To: Tomcat Users List Subject: Re: Getting a servlet running under Tomcat-Apache 4.0.3 What path does the Manager display for your app? If tomcat is auto-deploying your app, then it should be /MySeatMap since that is the subdir of webapps in which your WEB-INF/web.xml resides. Then you should be accessing http://localhost:8080/MySeatMap/seating If you are using a Context path=/mypath docBase=MySeatMap / element in server.xml, then your URL should be http://localhost:8080/mypath/seating Remember, the servlet-mapping elements only tell the container which servlet classes to invoke WITHIN that servlet's context path. Nothing in web.xml defines the context path itself. Try the above URL's and let us know if it works.
