Re: Problem in Tomcat 5.0.19 - Help Needed

[Andres Ledesma]

Hi Ramachandran,

You can check out your session, if it is new, include the page, otherwise do 
not do it.

another servlet-mapping question,.............

[Andres Ledesma]

Hi everybody, 

I got several servlets mapped on the web.xml file that works pretty fine on my 
local tomcat installation, but when uploaded to the hosting server, I get a 
400 Server Statuts Error, it complains the path to the server does not exist 
!!!

My web.xml for the servlets is like this code ...


validate_user
com.bs.crm.validateUser 

..


validate_user
/validate_user  




Anybody can help  me ??

Thanx in advance !!

Andrew

Well, the servlet can set attributes on the user's session and latter you can 
check whether this attributes have been set, you can even know whether it's a 
new session or an older one. 

There is a book 'moreservlets ans jsp' thar explains it very well, but is a 
sage of 'core servlets and jsp', that is entirely in 'www.moreservlets.com'.
Any way, I send you a snippet of code where I verify and set something in the 
session 

  /** Processes requests for both HTTP GET and POST 
methods.
 * @param request servlet request
 * @param response servlet response
 */
protected void processRequest(HttpServletRequest request, 
HttpServletResponse response)
throws ServletException, IOException {

String username = request.getParameter("username");
String password = request.getParameter("password");

HttpSession session = request.getSession(true);

try{
aUser usr = new aUser();

if( usr.IsAValidUser(username, password) ) 
{

UserSession user = (UserSession)session.getAttribute("user");
if ( user == null)
{
user = new UserSession();
user.setIsLogged(true);
user.setIsClient(true);

session.setAttribute("user", user);

}
else
{
user.setIsLogged(true);
user.setIsClient(true);
}


}

}
catch(Exception e)
{
;
}

..  ;

}

Hope this help

Re: restricting access to jsp pages

[Andres Ledesma]

Hi, 

I have not much experience with jsp, but I do not think this is the right way 
of doing that, your app have not to be inside WEB-INF. 

To prevent people accessing your pages, you check the user session, if for 
example, this pages can be view only by registered users only after a login, 
or something that is already there by I do not know very well, but I you can 
do a little research by yourself are the filters.

Hope this help. If you find something usefull, say something back ..

Good luck !

Andrew

Re: Making index.jsp work as welcome page after upgrade

[Andres Ledesma]

sorry, I think I did not write what I meant to say.

the point is to set the default port to 80, instead of just comment the 
default setting of port 8080.

It should be something like ...





sorry again

newbie simple question...

[Andres Ledesma]

Hi everybody,

I'm pretty new to Tomcat and jsp development, I'm running tomcat 4.1 over red 
hat 8. 

I redirected default port to 80 on server.xml, and created an index.jsp page 
in wich I insert other jsp pages I created as templates usign :

 
 
... etc

In the beginning it worked fine, but at some point it stoped working, so after 
issuing an http://localhost, just a blank page appears, so obviously, that 
header.jsp and footer.sjp are not found anymore..

Testin I did insert a <%= new java.util.Date() %> just above the include 
directive, and it works fine, I get the Date Time anwser, but not the page I 
asked to be inserted for...

I been looking around, trying to find something in previous postings, but I 
couldn't get anything, so I write here hope anybody can help.

Thanks in advance
