Tomcat problems
Hi, I'm very new to Java and JSP. I am having problems running JSP pages with the Tomcat Webserver. (I hope somebody is familiar with this) When I set up Tomcat in NT and go to one of the example JSP pages it comes up with an Error 500 in Netscape and a bunch of errors on the console. I'm pretty sure I just forgot to set up something, but any advice you can give would help alot. Remember I am absolutly new to Java and JSP, so I might have forgot to install something. FYI, the only things I installed were Sun JDK 1.3 Jakarta Tomcat Thanks === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Problems with Tomcat
Hi, I'm trying to set up Tomcat, the apache java servlet and jsp server on an NT machine. I installed the JDK 1.3 from sun and then the most recent Tomcat from Jakarta and thats it. When I go to view the example pages they have set up, the servlet pages work fine, but the jsp ones cause errors in the browser (in both Netscape and IE) and on the server's console window. I'm its something on the setup side that I haven't done yet, but I dont know what I should do. Any help would be appreciated greatly. I already tried copying tools.jar into the tomcat\lib folder as someone suggested, but I'm still getting the same errors. If it helps I've put the errors from the server side below. I'm pretty new to java so it might be somethign really dumb I forgot. Thanks, Pete Unhandled error!

JavaBeans Compile?
Ok I am starting to use JavaBeans with JSP pages. I've never made a 'bean' before and I was wondering how to do it. When I try to recompile the code to a bean I dont get errors (using normal javac 'filename') but when the jsp pages comes up it has errors. The code isnt messed up because I am using the code for an example that works. Is compiling a bean different than compiling normal Java code? Also do I need Java Enterprise Edition SDK 1.2.1? I have the Standard Edition SDK 1.3. (When I tried to install the J2EE it didnt have javac in it and I was all confused) Please explain if this is the reason. I just started programming in java and don't know the basics. Thanks. Thanks Pete === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

JSP Login Help
Hi, I'm very new to JSP and Beans. I have to create something that users will log into from a jsp page and a bean (i suppose) keeping track of who is logged into the system. (There can be multiple people at once) I think the best way would be to create an collection (like a vector) of HttpSession objects, one for each person logged in, but I'm not sure. Also, I just can't figure out how to do this. I read the information on HttpSession objects that came with Jakarta-Tomcat server, but I dont get how to implement it. If anyone can suggest a better way to do this, or knows some example code I could look at please email me. Thanks.

Please Help
Ok I am new to JSP (excuse for not knowing this) I just put all my JSP pages and beans into one directory. I'm using Jakarta-Tomcat. Now the JSP pages cannot fin the beans. For example Neither of these two beans are in a package. So what am I doing wrong? Tomcat gives the following error in konsole to make me think that it is not finding these beans... Java.lang.NoClassDefFoundError: LoginBean (wrong name: admin/LoginBean) If anyone knows what I can do (or what I'm talking about) please helpthanks Pete === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Custom Tags and Beans
Hi, I'm try to get a reference to one of my beans inside the code of a Jsp Tag I'm making. When I declare the bean's scope to be page, and use the following statement in my Tag's doStartTag BeanName log = (BeanName)pageContext.getAttribute("BeanName"); (where BeanName is the name of the bean ;) everything is ok., but my bean is supposed to have a scope of application. So when I switch it to application, and use that line, log is null. So how can I get this object? I guessed that maybe applicationContext.getAttribute would work but it does not. Thanks.

Thanks, I used the findAttribute and it worked. -Pete On Thu, 01 Jun 2000, you wrote: > Pete Walsh wrote: > > > Hi, > > > > I'm try to get a reference to one of my beans inside the code of a Jsp Tag I'm > > making.

Re: Tomcat wierdness
You could try using getParameterValues. This would give you an array of Strings for all the values of B. B:<%String b[] = request.getParameterValues("b"); for(int i=0;i I'm not saying this would work definatly cause I'm using Tomcat without Apache and Linux, but it works on my system.

JSP precompiled
Hi, Since JSP pages are compiled before being used (I believe), if a user #1 goes to a page that outputs a list of things from a database, then user #2 goes to that same page, will user #2 get a faster response since the pages is already compiled, or will the page be compiled again since the DB may have changed? If I'm way off base with this question please explain why. Thanks Pete === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".
