Problem upgrading from struts-1.0-b1 to struts-1.0
After upgrading from struts-1.0-b1 to struts-1.0 I keep getting a servlet error with the message "can't remove attributes from request scope". This is especially annoying because it occurs in the login JSP of my application and thus it blocks my progress. I checked the installation notes several times to see if I overlooked something, but found nothing wrong. Does anyone have a suggestion? (In the mean while I'll just add the Struts source to my project and debug through it.)

Checked radio buttons
I'm trying to find out if it is possible to set a radiobutton to checked using the HTML tag library. The documentation does not describe it. Regards, Guus Guus Holshuijsen, VideturHorsten 1, unit 1.185612 AX Eindhoven The NetherlandsT:+31-40-2450214 F:+31-40-2939343 M:+31-6-25077204

Re: Displaying errors when validating forms (ActionErrors)
Do you save your errors?
// Report any errors we have discovered
if ( !errors.empty() )
{
saveErrors( request, errors );
}

Re: Displaying errors when validating forms (ActionErrors)
Hartmut,
I do it at the end of an action's perform() method using the "construction"
given in my previous reply!
What I describe is only valid if your controller checks for errors itself.
In case you let Struts handle the validation automatically, I advice you to
look at the Struts source code.
The following code snippet is from the Action.java class:
/**
* The request attributes key under which your action should store an
* org.apache.struts.action.ActionErrors object, if you
* are using the corresponding custom tag library elements.
*/
public static final String ERROR_KEY = "org.apache.struts.action.ERROR";
Concluding: the errors are stored in the request (session?) attribute
"org.apache.struts.action.ERROR".
Regards,
Guus

HTTP requests in struts-config.xml
I would like to use the following request in a forward of an action in my web application's struts-config.xml file:"/doorman.do?action=lfadm.list&ci=0" But when I put in: I get XML parser errors when Tomcat starts up. And when I put in: I find that Struts does not interpret this as a parameter 'action' with value 'lfadm.list' and a parameter 'ci' with value '0' but as a parameter 'action' with value 'lfadm.list&ci=0' (note the change of %26 into &). The questions I have: 1. Is Struts designed to handle these kind of requests in a forward in struts-config.xml? 2. If the answer to 1 is yes: am I doing something wrong, or did I run into a Struts bug? 3. If the answer to 1 is no: What's another option?

Problem with tag?
I am using Struts 1.0 on Tomcat 3.2.1. When I try to use I get the message "According to TLD attribute key is mandatory for tag message" The message is incorrect, at least if I am to believe the documentation of the BEAN TLD! Does anyone has any experience using "name" & "property" instead of "key"? Regards, Guus Guus Holshuijsen, VideturHorsten 1, unit 1.185612 AX Eindhoven The NetherlandsT:+31-40-2450214 F:+31-40-2939343 M:+31-6-25077204
Re: Problem with tag?
The documentation for the tag states the following:
"Retrieves an internationalized message for the specified locale, using the
specified message key, and write it to the output stream. Up to five
parametric replacements (such as "{0}") may be specified.
The message key may be specified directly, using the key attribute, or
indirectly, using the name and property attributes to obtain it from a
bean."
So what I expect is that I can use the name and property attributes to
retrieve a message key from the "ci" property in the "<%=
Constants.STATS_KEY %>" bean!

Guus

Re: Accessing JDBC-ODBC from Struts
One of the - more complicated - solutions is to set up Java Naming and Directory services (JNDI, see the documentation that comes with JDK1.3). Using JNDI you can hide the details of connecting to your database(s) in a DataSource object you store in the naming service. Sun provides us with a "com.sun.jndi.fscontext.RefFSContextFactory" class that provides a filesystem naming service.

Re: problem
Are you sure that you have an "input" entry in your action mapping in your
struts-config.xml file pointing to the JSP where you want to end up?
If you don't provide an input entry you forward into the blueand not to
the JSP where you expect to end up.
You could also use the relative URL of your JSP to create an actionforward
(new ActionForward( "" ))

Re: Validating a form
Alexandre,
The input attribute must be added to the action mapping as follows:
where the "input" attribute should contain the name of the JSP you use to
input for the requete action (I assumed it to be '/requete.jsp').

Hi agian,
Excuse me for being late in my response but i'm currently between too
projects...
Craig, when you say :
"Note that you *must* specify an input attribute on your , so that
Struts knows where to send the user back to."
What do i need to do, what is the name of this input attribute?
Do you have an example of struts-config.xml code matching the case.
Here is mine:
http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd";>
I beleve there is something missing in the action node, but what?
Perhaps struts does not know what page to display when finding errors. How
can i tell it where to go? (another forward???)
Thanks for help.

Re: session ids
You can retrieve the current user's "session id" from the HttpSessionBindingEvent e using "e.getSession().getId()". Use this value to look up an entry in your hastable and remove it. The HttpSessionBindingEvent is generated when the session is invalidated (valueUnbound()) or created (valueBound()). For more details read the Java doc on HttpSessionBindingEvent. Make sure your class maintaining the hashtable implements the javax.servlet.http.HttpSessionBindingListener interface.
