Re: jsp:useBean / Scope Bug in 4.01 !
I agree, the id's are unique.
Could you attache the generated source file?
I'm unable to reproduce this with a build from the HEAD
branch, so I'm curious what the difference (if any) is.

is there am i declaring the same ID twice?

Hi,
Can you explain what you mean by:
Duplicate ids found in the same translation unit
shall result in a fatal translation error.
What is duplicate? I am declaring 2 seperate beans based on the condition.
Neither of them should be visible to the rest of the page. Yet they are
visible to Tomcat. The
JSP follows the XML syntax rules, which look at the *static* content of
your document at compile time. As it examines the incoming text, it
discovers that, in fact, you *are* declaring the same ID twice --
conditional execution is a runtime thing, not a compile-time thing.
Short answer -- you can't do that.
Lou

Subject: jsp:useBean / Scope Bug in 4.01 !
Hi,
The following is a bug I found using Tomcat 4.01 on NT4
The following code:
% if (request.getParameter(type)!= null
request.getParameter(type).equals(user)) { %
jsp:useBean id=user class=com.rutker.UsrData scope=request/
% } else if(request.getParameter(type)!= null
request.getParameter(type).equals(group)) { %
jsp:useBean id=group class=com.rutker.GpData scope=request/
% } %
should not be visible to the
jsp:getProperty name=user property=firstName / tag farther down
the
page because the useBean tag was declared in the if block, yet the
jsp:getProperty tag can see it and works in Tomcat. I noticed the bug
when I
tried the above code on WL 6.1 on Linux and it didnt work. I think that
WL
has the proper implementation.
I don't. They are violating the JSP Specification if they support this.
In the JSP 1.3 Specification, Section 4.1 (page 68), you will find the
following statement:
Duplicate ids found in the same translation unit
shall result in a fatal translation error.
The fact that you are doing this inside scriptlet conditionals does not
change the fact that you are using two jsp:useBean elements with the
same id attribute in the same page.
Is this the correct mailing list for this post?
The best place to report bugs is in the bug tracking system:

Re: SV: Setting the alocated memory to Tomcat 4.0.1

Re: RH Linux 7.1 Java Error
Hi, In regards to the hanging issue, if you stick with 1.3.0_x on RH 7.1 you will need to export LD_ASSUME_KERNEL=2.2.5 or if you upgrade to J2SE 1.3.1 you won't have to export the above flag. Regards, Ryan Lubke Andrew Robson wrote: Hi, Your problem is that 'cut' is in the wrong place. Copy it from wherever it is (/bin I think) into /usr/bin/ This will get rid of error message but you're not out of the woods yet. See the thread from yesterday about a missing file - libstd++-libc6.1-1.so.2 I suspect you will get the same problem. I searched redhat to find the package this file belonged to and installed via rpm. Had to force it as believe it is a 'downgrade' of an existing package. If you get this far you should rid yourself of any error messages but you may well find that javac and java just hang when you try to use them. At this point I gave up and switched to RH 7.0. I'm sure a couple of days later I came across something on the web about a fix to 7.1 to prevent the jvm hanging problem. But I can't remember where or the details. Search the Redhat support forums would be a good place to start. It may be something specific to particular version of jdk which you will avoid because you have the latest (?). good luck andrew On Fri, 10 Aug 2001, you wrote: Hi all, I know this is perhaps not the most appropriate place to present this question as it is a purely java installation problem.

Re: How to configure a custom page for JSP 404 errors?
Hi Pierce, From what I've been able to gather, you should be able to set the error page using the error-page directive within the deployment descriptor for a web app (web.xml). error-page error-code404/error-code location/error.jsp/location /error-page Looking through the bug database, there was an open issue regarding the use of static html pages within the location tag. I'm uncertain at this time what release it's actually fixed in, but if you try it and get a stacktrace, then I guess you know :) The bug report can be found here: http://nagoya.apache.org/bugzilla/show_bug.cgi?id=291 I did find this information in the archives. Try looking at the results of the following search: http://mikal.org/interests/java/tomcat/archive/search?search=error+page+custom+404 I'm sure those who are more experiences could expand/correct on this information. Hope this helps. -rl Courtney, Pierce wrote: Hello, This question probably has come up before, I just can't find it in the archives I am using Tomcat 3.2.2 standalone (not with Apache). How can I configure a particular page (servlet, static html, or jsp) to be the default page that comes up if the requested jsp is not found, instead of the 404 error. In other words, if a user requests: http://myTomcatSite.com/somePage.jsp I want to have somePage.jsp come up if it exists. But if somePage.jsp does not exist, I *don't* want the default 404 error to be displayed. Instead I want some custom page (a servlet actually) to be processed. I don't really care if this is achieved with a client-side redirect or a server-side include/forward. I have tried using the DefaultServlet, which doesn't seem to work. I have also set up my own servlet against url-pattern /* /url-pattern. This works for servlets only, not JSPs. It seems the basic problem is that any URI that matches *.jsp. gets processed by the JspServlet. So it is not determined if the .jsp file actually exists or not until the JspServlet is triggered. Can this custom error page functionality be configured somehow in Tomcat? Thanks for any help, Pierce Courtney [EMAIL PROTECTED]
