Intercepting AuthenticationFilter and dispatching need help !
Hey all,
i want to check if the user is authenticated.
I've read that the Filters are the right place to do that.
If the User is not authenticated, so i want to dispatch him to a login page.
Does anybody knows how to do that ?
I've tryed it in the Filter in this way:
((HTTPServletRequest)servletRequest).getRequestDispatcher( "pub/ueberweisung
.jsp" ).forward( servletRequest, servletResponse );
But there is always an Error compiling the jsp ?!
if I call this jsp (plain html) without a filter it works without any
problems ?
Pleas help....
Fredy

Can I make a jsp custom tag to return a value in to a jsp variable.<p>
I want a jsp custom tag to evaluate some condition based on the parameters I
pass and return a boolean to the jsp page in a java variable (type
boolean).<p> Can anybody give some sample of the code using similar
functionality. <br>Can we some how use the get methods in the tagHandler in
our jsp to retrieve the values?

Is it possible to invoke customtags onEvents like onClick?

1. My application is under /opt/tomcat/webapps/myApp

3. My web.xml is: /opt/tomcat/webapps/myApp/WEB-INF/web.xml

What am I doing wrong?
http://www.jguru.com/misc/faqtrampoline.jsp?src=notify&EID=592461
I'm working on the JSP - Tomcat model, I'm using JSPC to pre-compile my
JSPs, Is there a way to prevent any new (non pre-compiled) JSPs from being
executed (compiled) in tomcat? ie. I do not want any new JSPs , which have
not being pre-compiled to be executed via tomcat on the browser, Is there
any property/configuration file which I need to change in Tomcat??
http://www.jguru.com/misc/faqtrampoline.jsp?src=notify&EID=592460
Why use JSP? All that we can do with scriptlets we can do with JavaScript as
well, I think.
Can somebody explain?
http://www.jguru.com/misc/faqtrampoline.jsp?src=notify&EID=590882
We are building a series of JSP pages, each of which is responsible for
producing a different area of the screen.
Any given screen that the end user sees, therefore, is made up of a number
of "blocks", each of which has been generated by a single JSP. The top level
JSP calls in the "blocks" using a jsp:include.
We are trying to use the JSP errorPage directive on every JSP to display an
error to the user if something goes wrong with any of the "blocks", but are
finding that we end up with the error page only taking up part of the screen
(for the block which had an error), whereas we would like the whole screen
to be filled up by the errorPage.
In other words - if something goes wrong with any of the blocks that
comprise a screen - we would like to display nothing but the error page.
What is the best way to do this ?

HttpUtils.parseQueryString is deprecated. What should we use instead ?
http://www.jguru.com/misc/faqtrampoline.jsp?src=notify&EID=587251
In some web.xml I find DOCTYPE reference of "web-app_2_2.dtd",(in Weblogic
5.1 example) in others, of "web-app_2.2.dtd" (in java pet store). What is
the difference between the two DTDs?

What are the steps that I need to follow to deploy my servlet in WebLogic
6.1?
http://www.jguru.com/misc/faqtrampoline.jsp?src=notify&EID=586701
How can I suppress the parameters from displaying in the URL? For instance,
if I pass in a password, I don't want it to show up in the address bar.

Fredy,
Would you please show us exactly what you do, as I need to do the same sort
of thing?
I had a version that worked under 3.2, but it fails under Tomcat 4.
Thanks
