Re: jsp:useBean / Scope Bug in 4.01 !
Back to the basic question where in this 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/
% } %
is there am i declaring the same ID twice?
Thanks

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.

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?

Config crashing Tomcat 4.01
Hi, I am new at this and the way I mapped my servlet might be odd but crashing tomcat wasn't what I expected. I am running Tomcat 4.01 standalone on NT 4 SP6 I am starting it using the shortcut provided by the installation (\Apache Tomcat 4.0\bin\bootstrap.jar start) and stopping it with the stop shortcut. Here is what I did. My web.xml is as follows: web-app servlet servlet-nameGenServlet/servlet-name servlet-classGenServlet/servlet-class /servlet servlet-mapping servlet-nameGenServlet/servlet-name url-pattern/controller/url-pattern /servlet-mapping servlet-mapping servlet-nameGenServlet/servlet-name url-pattern/GenServlet/url-pattern /servlet-mapping !-- next mapping causes problems -- !--servlet-mapping servlet-nameGenServlet/servlet-name url-pattern/*/url-pattern /servlet-mapping-- /web-app It works and when I hit http://localhost:8080/anyservletName?action=addtype=user I get exactly what I expect. But when I tested an oddball url as follows: http://localhost:8080/?action=addtype=user just passing the params to nothing I get the index page (wasn't sure I would get the index page or the servlet- now I know). At this point any servlet or JSP I try to invoke the system throws a 500 Internal Server Error The root cause is: java.lang.StackOverflowError (the longest stack trace I have ever seen - not sure this is common in tomcat). This in itself wouldn't be that bad if I could shut down Tomcat. It doesnt fully shut down using the shortcut (the start Tomcat window doesnt shut down a message appears Stopping service Tomcat-Standalone and it hangs. When I manually shut the window and kill every thread I can see that I think is associated with the process (java ones). Note The problem as I know it is ONLY when trying to do a forward. Just passing the servlet the parameters ?junk=someJunk will pose no problem. It is only when the parameter triggers the servlet to do a forward to a jsp page that causes the exception. The only way to restore it is to rebooot. I did clear out all the cache in the work folder.
