Accessing Request URI using struts tags
I am trying to do the following from within a jsp, using Struts tags <%@ include file="bla.jsp" %> However, I cant seem to find the tags to do do this. I would have imagined that one could do something like: <%@ include file="bla.jsp" %> but this does not work. Any adivice would be helpful. Sorry for the newbie question. Luggage? GPS? Comic books?

RE: Connection, pool exhausted error
I thought that closing the connection was unnecessary when using a
connection pool. I was under the impression that one would just close
the context, which would return the connectin to the connection pool.
Is this not the case?

Connection, pool exhausted error
I am getting a connection, pool exhausted error, in the action class
below.
The error happens exactly after the hundredth connection, even though I
have
closed all my statements, result sets and contexts. (I know that one
would not normally do db access in an Action class, however, I'm
implementing a quick and dirty presence detection for an external
service, and dont need to worry about elegance.)

Re: getting Session from SessionId
I think its going to have to be solution 1. All Im really interested in is user data associated with a session, so I'll probably map userId to sessionID in the DB and then pull user info when the service sends me a session id. I like the idea of the session map though. Maybe use a singleton to store the map and then access the sessions from there. Why do you say this might not be a good idea? --- "Frank W.

getting Session from SessionId
I am trying to integrate a web application to an external service, and need to be able to take an incoming sessionId from the external service server, and to return details from the session to which that sessionId applies. I understand that there was a getSession(String sessionid) method, in HttpSessionContext which has since been deprecated. Does anyone know how I would do this, with the Servlet 2.3 APIs?

Struts considering exceptions in Action class .execute() as unhandled
I have an action class with an execute method as follows
public ActionForward execute( ActionMapping mapping,
ActionForm form,
HttpServletRequest req,
HttpServletResponse res
)
throws Exception
{
try
{
Do something innocuous;
Foo foo = new FooWhichThrowsAnExceptionInConstructor();
}
catch (Exception e)
{
mapping.findForward("goto_graceful_error_page");
}
}
But instead of going to the graceful error page the user gets the HTTP
Status 500 - page and I see the following in the error log.
org.apache.struts.action.RequestProcessor - Unhandled Exception thrown:
class java.lang.Exception
I put debug println's around the code and found that execution stopped
immediately at the call to the foo constructor, and the catch block was
never entered.
I am not doing anything outside of the try block. Is this behaviour
standard in struts? Shouldn't I be going to my graceful error page?
Can anyone shed any light on this?

Logging in Struts
Good day
I am having a hard time understanding how to use logging in Struts.
The struts.apache.org suggest the following usage (presumably for
business objects) (taken from:
http://struts.apache.org/1.x/userGuide/building_controller.html )
package com.foo;
// ...
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
...
public class User {
// ...
private static Log log =
LogFactory.getLog(User.class);
// ...
public void setBar(Bar bar) {
log.trace("Setting bar to " + bar);
this.bar = bar;
}
// ...
}
The suggestion seems to be that it is OK to declare my Logger as a
static variable in the business object. This is ideal for me because,
I will be accessing the Logger from both instance and static methods,
and so I do not want to have to declare this as an instance variable.
However, I am wondering whether this is OK, given that my business
objects will be being accessed from different servlet threads. Can
anyone tell me whether this is OK?, and if not, what is the correct way
to do this?
My second question is whether the same usage is valid for Action
classes. I saw the following example, at
http://www.mobilefish.com/developer/struts/struts_quickguide_log4j.html
but am not certain as to whether using a static variable would be OK
here. Would it?
public class DemoAction extends Action {
private static Log log =
LogFactory.getLog("com.mobilefish.DemoAction");
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
log.debug("This is my debug message.");
log.info("This is my info message.");
log.warn("This is my warn message.");
log.error("This is my error message.");
log.fatal("This is my fatal message.");
}
}
The commons logging documentation notes the following:
Note that for application code, declaring the log member as "static" is
more efficient as one Log object is created per class, and is
recommended. However this is not safe to do for a class which may be
deployed via a "shared" classloader in a servlet or j2ee container or
similar environment. If the class may end up invoked with different
thread-context-classloader values set then the member must not be
declared static. The use of "static" should therefore be avoided in
code within any "library" type project.
I'm not clear as to what the above means, from a practical perspective
in the context of a web applicaiton. What does this mean in simple
terms?

Re: OT: Tomcat not setting session cookies ? Please help :(
Thanks Craig Tomcat is not only doing this on the first page, but also on all the subsequesnt pages. And theres no jsessionid cookie in the cookie folder. I also disabled the firewall, to see if the cookie was being blocked there.

OT: Tomcat not setting session cookies ? Please help :(
Hi All of a sudden tomcat has stopped settign session cookies. I have been developing on my local machine for approx 1yr. Now, When I goto my webapps home page: http:/127.0.0.1:8080/webapp), tomcat is rewriting the URL as http://127.0.0.1:8080/webapp/Welcome.do;jsessionid=DAF0604E76E234C157A9BFDF53FD2617, indicating that it is not setting a session cookie. When I check the session cookie folder C:\Documents and Settings\user\Cookies. There is no jsessionid cookie. When I set a cookie from within webapp, the cookie is set as normal and stored in the cookie folder C:\Documents and Settings\user\Cookies, and is retrieved by my web application. Why is Tomcat not setting a session cookie? I configured my browser to accept all session cookies. I am using Windows XP Pro, with IE6, j2sdk1.4.2_08, Tomcat 5.0.28. This has been working as it is supposed to for 1 year. Can anyone explain what is going on? __ Do You Yahoo!? Tired of spam? Yahoo!

Re: urgent- exception in sending e-mail from application

Your smtp server may require authentication. Find out and, if so, Add
the following lines to your code.
class MyAuthenticator extends Authenticator
{
protected PasswordAuthentication getPasswordAuthentication()
{
PasswordAuthentication pa =
new
PasswordAuthentication(username,password);
return pa;
}
}
props.put("mail.smtp.auth", "true");
Authenticator a1= new MyAuthenticator();
Session mailsession = Session.getDefaultInstance(props, a1);

not detecting hidden parameters in multipart forms
I am using hidden fields and multipart forms in a jsp, and it seems that the tag is not detecting the hidden field as being present when the multipart form is submitted. In MyJsp I have Myvar is present etc I have configured this page to use the struts validator and to redirect back to itself if validation fails. When it redirects to itself the "myvar is present" message does not render. This doesnt seem to happen for parameters. Eg. If I replace the tag with Mytext is present and I submit the multipart form with mytext field populated I DO get the "my text is present" message. Also, if I remove the enctype="multipart/form-data" attribute from the tag, the hidden field seems to be detected ok, and the "myvar is present" displays. Has anyone come across this before, and/or does anyone know what I might be doing wrong? __ Yahoo! DSL Something to write home about.

Tomcat not displaying (or logging) runtime exceptions for STRUTS !!
Please help. It seems that Tomcat is no longer displaying (or logging) runtime errors. I have in a jsp, and no tags surrounding this. If I call this jsp without the var parameter, Tomcat just returns a page with the following html source: Thats it! No exceptions or anything! So theres no way to debug the jsp Shouldn't I be getting a: javax.servlet.ServletException: Cannot compare null variable to value null with root cause: javax.servlet.jsp.JspException: Cannot compare null variable to value null ?

Re: Action.execute() only being invoked the first time a url is requested ??!!!
It's understandable that my browser would retireve from cache when I hit the back button. BUT: Should my browser also be retrieving from cache when I click on the same url twice, even if the url/uri is a get request. I am implementing a logout link as follows: login.do?use_case=logout When I click on this link twice my Action.execute() is not being invoked. According to the HTTP Specification (section 13.9 - http://www.w3.org/Protocols/rfc2616/rfc2616-sec13.html#sec13): since some applications have traditionally used GETs and HEADs with query URLs (those containing a "?" in the rel_path part) to perform operations with significant side effects, caches MUST NOT treat responses to such URIs as fresh unless the server provides an explicit expiration time. This specifically means that responses from HTTP/1.0 servers for such URIs SHOULD NOT be taken from a cache. See section 9.1.1 for related information. --- Michael Jouravlev <[EMAIL PROTECTED]> wrote: > Browser is not obliged to reload non-cached page > when a user navigates > back in browser page history.

Re: Can RequestDispatcher be used in an Action class
Thanks Lorrie. I hadn't realized that one could return a null mapping. More than likely I will redirect to the referring url using a dispatcher. Does that sound like the best way to redirect to the referring URL/URI? This url would more than likely be another "blaBla.do" page. I am presuming that if I tried to generate an ActionMapping on the fly or use a global forward, that there would be more work with little added benefit. --- Laurie Harper <[EMAIL PROTECTED]> wrote: > Mon Cab wrote: > > I am trying to build a login page which will > direct > > the user to a different page depending on what > action > > they were trying to perform before they logged on. > > > > > I was thinking of using a passing a request > parameter > > in the request for the login page which could be > used > > by a request dispatched in the LoginAction class, > but > > dont know how that would square with returning an > > action Forward using the findForward method. > > > > Is there any way of doing this, Or is there a > better > > way of doing it using ActionMapping's? > > Assuming the request parameter you're talking about > is a URL to forward > to, you have two options: do the redirect yourself > and return null from > the action; or construct an action mapping 'on the > fly' with the > appropriate URL in it. > > Which you choose depends on what you want to pass in > as the request > parameter.

Can RequestDispatcher be used in an Action class
I am trying to build a login page which will direct the user to a different page depending on what action they were trying to perform before they logged on. I was thinking of using a passing a request parameter in the request for the login page which could be used by a request dispatched in the LoginAction class, but dont know how that would square with returning an action Forward using the findForward method. Is there any way of doing this, Or is there a better way of doing it using ActionMapping's? __ Start your day with Yahoo! - Make it your home page! http://www.yahoo.com/r/hs - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Action.execute() only being invoked the first time a url is requested ??!!!
Thanks Atta. It is reloading the pages now.
PS. Is this default behaviour for STRUTS? And if so,
do you know why? It seems to me that the default
should should be not to cache pages with dynamic
content.
Is there a way to configure this in Tomcat or in the
struts config?

Action.execute() only being invoked the first time a url is requested ??!!!
For Example if I type in my browser address bar:
http://127.0.0.1:8080/webapp/userSignup.do?action=whatever
The first time, I type this in, this invokes the
execute method of my Action class (I'm using
System.out ("Action execute Invoked") in Action
execute to test this). If I then enter the exact same
url, this method is not getting called.
I am not using validator at all!!
Can anyone explain what is going on with this?

Re: Runtime debugging - and Painfull Tomcat restarts
Laurie & Paul Thanks for your help on this one. Is there any way that this could be configured to just reload the specific classes that were changed, rather than reloading the whole app? Also, I read the link you gave to "set context reloadable to true", but couldn't quite see which file I would set that in.

Thanks Paul. I didn't realize that it was possible to

items in any set of parens).

Problems with "validwhen"
I am trying to use validwhen to make sure that
validator only requires a valid State and Zip if the
country selected is "United States".
But I am getting required error messages from both
state and zip when the form is submitted without these
values.
I am using the following config for validator:
test
(country=="United States")

test
(country=="United States")
mask

Re: How to display an error image next to an invalid form field?
Thanks Laurie
How would you write this. The usage doesnt seem to be
clear from the tag API.

Re: How to display an error image next to an invalid form field?
Lauri I want to do this: Forgive the "pseudo"-tags. I don't know if there are struts tags in to do this... I know will give me the error message for username, but I don't care about that. I just want to display the error arrow. Do you know how this would be done? --- Laurie Harper <[EMAIL PROTECTED]> wrote: > Mon Cab wrote: > >>I have read the struts documentation and am trying > >>to > >>work out how I would display an error image next > to > >>an > >>invalid form field. > >> > >>Ramesh mentioned that >>property="custName"/> would display the error > >>message > >>associated with a particular field.
