Re: Deactivate URL-rewriting in logoff action.
What I was trying to say is that when logoff action is called, my application ends and the user goes to another location. Although I invalidate() session in logoff, when ActionServlet forward to next page creates a new session that is not really used by anyone. For example, I want user to go to www.altavista.com after logoff action so I don't need new session. action path="/logoff" type="com.company.package.LogoffAction" forward name="finish" path="http://altavista.com" redirect="true" / /action Thaks "Craig R. McClanahan" wrote: On Thu, 15 Mar 2001, Ana Narvaez Vila wrote: Logoff action usually invalidates session and sends browser to a index or welcome page, so it is not necesary to rewrite the URL. ActionServlet must have a session, so if there isn't a valid session it creates one. Question is: Is there a way to say to ActionServlet not to create a new session ? It's not just the controller servlet that creates sessions -- JSP pages do as well, unless you tell them not to with a page directive: %@ page session="false" % However, trying to run Struts based apps completely without sessions is going to cause you some grief in the following areas: - Internationalized message lookups in the bean:message tag depend on a Locale object stored in the user's session, which indicates this user's current Locale preference. - The html:errors mechanism for displaying validation errors relies on the same thing, so you cannot use this. My advice would be to go ahead and let the sessions be created, and minimize the memory occupancy by using request scope (rather than session scope) for all your application's form beans. We're talking tens of bytes per simultaneous user for the session itself (and the associated Locale), so the memory requirements are not onerous -- even if it took 100 bytes per user, 10,000 simultaneous users is still only a megabyte. And you are pretty much certain to run into other resource limits (CPU, database, network) before you reach that many users anyway.

We're about to move to 3.5.3 from a working 3.5.2, so I'd appreciate a head
start. As the author of the 3.5.2 instructions, I'd like to know that you
changed the ActionServlet class and stored it in the servlet directory of
your web app.
I'm already on 3.5.3 and I've changed the ActionServlet class as you specified
it in the installations notes, before trying struts.

RE: WebSphere problem
We're running struts on WebSphere 3.5.3 and don't have any problems parsing the config file. We have not made any modifications at all to the ActionServlet class, it runs just fine out of the box. Maybe you could turn up the debug and detail init args to the ActionServlet to get a more specific trace, it's kind of hard to see what's going on. Are you sure that there's nothing wrong with the config file? On a side note: The only exception I've had during init was due to the fact that we had no web.xml file. Since that particular message seems to be missing from the ActionResources.properties file in struts 1.0 beta1 it was kind of hard to find... It cleared up fine when I created an empty web.xml file (or rather one containing web-app/) Why does Struts try to read web.xml? Shouldn't that be left to the servlet container? All init information is stored in the WebSphere database, so we don't really need a web.xml file... /Markus -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Friday, March 16, 2001 10:31 AM To: [EMAIL PROTECTED] Subject: Re: WebSphere problem [EMAIL PROTECTED] wrote: Can anyone provide a stack trace? here it is.

Okay, I've been trying to get my own struts apps going without much success. I get the following error: javax.servlet.ServletException: Cannot find ActionMappings or ActionFormBeans collection I also get the message: "cannot load servlet name action" I have everything in the places suggested by the user-guides and about 1 struts mailing list helpers, I don't have servlet.jar floating around or anything else obvious that might stuff it up. The example programs with struts all seem to work. It's only when I try to get some action classes or similar going that I get problems. I'm trying to run the app on tomcat3.2.1 in windows. Any suggestions/solutions? Thanks, Joel.

Here is the change in class GenericDataSource: I am just checking whether

connection has been closed by the database server. And if it has, then I
obtain
a new connection.
For this to work, you have to make sure that your jdbc driver is returning
the
correct value for the isClosed() method. Please try to ensure this first. I
am
saying this, because the Interbase jdbc driver Interclient 1.6 did not work,
PostgreSQL driver did not work, we had to patch it, only MySQL driver worked
ok.
I also attached the complete file GenericDataSource.java.

Other jsps use different properties of the form with no problem. Any
suggestions ?

BeanMessage Tag proposal
Hi,
When setting the args (arg0,arg1,arg2,arg3,arg4)
you must do this:
bean:message key="foo.foo.foo" arg0="foo1" arg1="foo2"/
But i think it is very rare that you know exactly at design time of the jsp
what value there must be. Because if you do then why not set it directly in
the message it self?
So it is almost any time a runtime expression.
But then i must do things like this:
bean:define id="argstring1" value="totalautotheft"/
bean:define id="argstring2" value="autotheft"/
bean:define id="insurance" name="carinsurance" scope="session"
type="nl.topicus.thema.DynamicForm"/
bean:message key="prompt.advise.wacasco" arg0="%=
insurance.getProperty(argstring1).toString() %" arg1="%=
insurance.getProperty(argstring2).toString() %"/
I must define
bean:define id="argstring1" value="totalautotheft"/
because i can't do this:
bean:message arg0="%= insurance.getProperty("totalautotheft").toString()
%"
I find this a bug of the Tomcat parser if you ask me. Because if he sees
that it is a reqexpr (%=)
then it should first find the % before looking at the closing "!!
Because if these problems i wanted to find a solution
Why is is not possible that i get the Object[] from a name/property???
Then the BeanTag is also not limmited to only 5 args
My example for the above one:
app:message key="prompt.advise.wacasco" (arg)name="insurance"
(arg)property="wacascoObjects"/
and the insurance.getWacascoObjects() does return the Object[] for that
string:
object[0] = insurance.getProperty("totalautotheft");
object[1] = insurance.getProperty("autotheft");
return object;

I think you do not need the jsp:useBean Tag but you need to define the
bean in the
"iterator" Tag. So you have to set the property name="JobQueueForm".
I use some quite similar lines of code in a test apllication:
logic:iterate id="result" name="TableRowActionForm"

Subclass of ActionServlet not registering correct locale...
Hi, We've created a subclass of the ActionServlet and arestoring a locale object in the session under the key Action.LOCALE_KEY. Apparently this has no effect on our rendered messages. Does anything special apply in regard to locale handlingwhen you subclass the ActionServlet ?? Any hints appreciated..:) Med venlig hilsen/Best Regards---Jannik Nørgaard SteenSoftware DeveloperDigital Zone International http://www.digitalzone.dkmailto:[EMAIL PROTECTED]---The most critical design decision youwill ever make is naming things...

Craig M. - Comments on Minimizing Action class proliferation
Craig,
Last week, there was a thread labelled: "Minimizing Action class proliferation". I
think you were on your brief "no list access" hiatus. :)
Below is the long-and-short of a proposed enhancement to Struts that could optionally
be used by developers if they are so inclined. The only piece missing from this is a
proposed change to the "action" XML elemen to include a "handler" or "method"
attribute. This would be used as the first parameter to the "class.getMethod" call in
the code below.
I won't regurgitate the whole thread here. I was just wondering if you had any
thoughts on this?
Thanks,
Donnie
[EMAIL PROTECTED] 03/07/01 10:05PM
Donnie,
How about this as an alternative. I have created a subclass of Action called
StandardAction which uses reflection to invoke a method with the same name
as the "actions" path (defined in the struts-config.xml file). So all you
have to do is extend the Standard action and implement methods that
correspond to the paths that use it.
For example if you define three actions in your struts-config.xml file of
/saveOrder, /editOrder and /deleteOrder that all use a class OrderAction
which extends StandardAction and then create a OrderAction class as shown
below:
I hope this is of use.
Niall
--Example of StandardAction implementation---
public class OrderAction extends StandardAction{
public ActionForward saveOrder(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) {
}
public ActionForward editOrder(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) {
}
public ActionForward deleteOrder(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) {
}
}
---StandardAction Class---
package nkp;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import org.apache.struts.action.ActionForm;

Re: Missing Property
On the same thread... can someone tell me why I can't put
property="aBCDefg" with a bean getter of "getABCDefg()"
Note the 2nd char being an uppercase "B". I were to make the "B" a
lowercase "b", it works. The problem stems from the 2nd char in the
property name being a capital. I'm on Tomcat 3.3m1 + Struts 1.0b1
Any advice? is this a bug?
Thx-

Re: Struts and Sun's J2EE Patterns
Jorge, Just catching up some email. Jorge Ribeiro Jordo wrote: Has anybody read Sun Java Center J2EE Patterns (http://developer.java.sun.com/developer/technicalArticles/J2EE/patterns/) yet ? For those that did, it seemed that Struts is pretty much an implementation of the "Front Controller" pattern (no surprises so far), using the "ServletFront", "Command and Controller", "Multiplexed Resource Mapping" and "Dispatcher in Controller" stategies. You've done an excellent job of understanding this pattern and describing the aspects of Struts it describes! The one minor clarification is about the 'Dispatcher in Controller' strategy. While I'm not a Struts expert, I believe that Struts uses a separate mapping mechanism that sits outside of the controller servlet, does it not? If the controller is delegating to an external component in order to do view mgmt (ie:choosing the view) and navigation (ie:actually dispatching to that view) then I probably wouldn't describe it as using the 'Dispatcher in Controller' strategy. This strategy is meant to describe more simplistic cases where the controller inlines the work itself, for example if it just grabs a string and a requestDispatcher instance and forwards things on their way. See the 'solution' section of the 'Service to Worker' pattern for a bit more discussion on this issue. 'Service to Worker' is a pattern that combines a couple other "smaller" patterns in the catalog into a larger one. Let me know if I got anything wrong wrt to the discussion of Struts in this email :-) I'm interested in any other comments on this issue (or others related to any of the Pattern material in the above URL - pls feel free to email the provided aliases, if you'd like to discuss outside of this list).

PaymentSearchActionPaymentSearchForm DisplayStmAction DisplayStmForm in the PaymentSearchForm I take in all the search conditions, like consultant name, stating date, ending date etc, then PaymentSearchAction will perform the search and get all the result set in the session, then I need populate all the result to DisplayStmForm, based on the setting in struts-config.xml, DisplayStmAction is the guy can access DisplayStmForm, then the question is How DisplayStmAction can take control from this point automaticlly, then I can populate the DisplayStmForm. By another word, how can I jump from paymentSearchAction to DisplayStmAction automatically, then I can use PaymentSearchAction populate PaymentSearchForm to do the search then automatically switch to DisplayStmAction to populate DisplayStmForm for the display. Thanks Frank Ling

Maybe you could turn up the debug and detail init args to the ActionServlet to get a more specific trace, it's kind of hard to see what's going on. Are you sure that there's nothing wrong with the config file? On a side note: The only exception I've had during init was due to the fact that we had no web.xml file. Since that particular message seems to be missing from the ActionResources.properties file in struts 1.0 beta1 it was kind of hard to find... It cleared up fine when I created an empty web.xml file (or rather one containing web-app/) Oops ... that is a bug. Why does Struts try to read web.xml? Shouldn't that be left to the servlet container? All init information is stored in the WebSphere database, so we don't really need a web.xml file... Struts needs to read the web.xml file to figure out what kind of servlet mapping you are using -- path-mapped or extension-mapped. This is needed in order to construct correct URLs in the html:form tag, when you just include the action name: html:form action="/logon" ... /html:form This will be translated into "/myapp/logon.do" if you are using extension mapping, or "/myapp/perform/logon" if you are using path mapping to "/perform/*". /Markus Craig McClanahan

Does your String array have any null values in it? There is an

Also, at one point the logic:iterate tag had a bug where it did not

Re: Subclass of ActionServlet not registering correct locale...
On Fri, 16 Mar 2001, [iso-8859-1] Jannik Nørgaard Steen wrote:
Hi,
We've created a subclass of the ActionServlet and are storing a locale object in the
session under the
key Action.LOCALE_KEY. Apparently this has no effect on our rendered messages.
Does the standard support for Locales not take care of your needs? Set
the "locale" initialization parameter to "true", and the controller will
store a locale for you if there isn't one present.
Second, how are you actually storing the Locale? Note the difference
between the following two statements:
session.setAttribute("Action.LOCALE_KEY", locale);
session.setAttribute(Action.LOCALE_KEY, locale);
The first one will not work correctly - the actual String constant that
Struts wants is the *value* of Action.LOCALE_KEY, which is
"org.apache.struts.action.LOCALE". You need to use the second form.
Does anything special apply in regard to locale handling when you subclass the
ActionServlet ??
Any hints appreciated..:)

Re: Connection Pool
On Fri, 16 Mar 2001, Christophe Vigny wrote: Where is the connection pool ? in tomcat, in turbine or in strut ? Turbine and Struts both have connection pool implementations. Struts can actually use any connection pool that implements javax.sql.DataSource -- it only defaults to its own. The Turbine connection pool, unfortunately, is not useful for this because it does not implement the DataSource interface. However, several other connection pool implementations available on the web are suitable. There is an ongoing discussion about creating a "Commons" project within the Jakarta framework to create and maintain shareable implementations of components like this -- and a connection pool is the primary example of the kind of code we all want to be able to share. Once the commons project is started, the physical source code for the connection pool Struts uses will move to the Commons project, but this move will have little or no impact on Struts applications (you'll need a separate JAR file, but that's easy to deal with).

Below is the long-and-short of a proposed

Donnie,
How about this as an alternative. I have created a
subclass of Action called
StandardAction which uses reflection to invoke a
method with the same name
as the "actions" path (defined in the
struts-config.xml file). So all you
have to do is extend the Standard action and
implement methods that
correspond to the paths that use it.
For example if you define three actions in your
struts-config.xml file of
/saveOrder, /editOrder and /deleteOrder that all use
a class OrderAction
which extends StandardAction and then create a
OrderAction class as shown
below:
I hope this is of use.

Re: chaining of actions
On Fri, 16 Mar 2001, Sachin Tendulkar wrote: Hi, Is there is a way in struts I can chain actions together.Like instead of going from an action to a jsp can i call another action after I am done processing one action? One way would be to set up a forward entry that points back at the controller servlet, rather than to a JSP page. The example application illustrates this -- in the "/saveSubscription" action, the "success" forward goes to "/editRegistration.do?action=Edit" which will flow back through the controller servlet again.

Jorge's initial comment is interesting, given the fact that as Ralph Johnson, Doug Schmidt, and Mohamed Fayad state in 'Building Application Frameworks', Wiley 1999 "Patterns are the architectural elements of frameworks.".

In fact, I've gotten some emails recently asking me to write a paper about the relationship of an existing framework and the Patterns.

RE: Unsafe path error
Windows will not let me create an all caps WEB-INF folder. I try and it lower-cases all but the first letter. Any more suggestions? Don't use Explorer. From a command prompt create the directory. Then, from the command prompt, verify that the directory name is all upper-case. Explorer tries to be helpful for the end- user, but this can often bite you. It will also display names that are in all caps and matching 8.3 by capitalizing the first letter and making the rest lower case. It does this because it thinks that you're using FAT without a long file name. -- Curt Hagenlocher [EMAIL PROTECTED]
RE: Unsafe path error
If you put WEB-INF in caps, windows will show it to you as Web-inf but internally it would 've made it all caps.

HTML paramter and its getter name
Hi, I have the following parameter defined in a JSP page using html:hidden tag: html:hidden property="CompanyID"/ In its correpsonding ActionForm class, there is a getter for it which name is "getCompanyID()". However, Struts can not find this getter: javax.servlet.ServletException: No getter method for property CompanyID of bean org.apache.struts.taglib.html.BEAN If I change "CompanyID" to "companyID", then problem is fixed. Can anybody tell me why? What is the right getter name for a parameter which starts with upper case letter? Thanks, - Guang
Re: Craig M. - Comments on Minimizing Action class proliferation
I also created something similar based on a Javaworld article. My Action
class takes a url like /objectX/methodX and lookes up in application scope
an object called objectX and invokes the method called methodX (via
reflection as below). The method signature is the same as that for perform
except I pass the reference to the Action class in case the class needs
access to certain data that only the Action class holds. In my Action class
perform method I can then do perform certain global rules like checking for
login, implementing some common routing algorithm, etc..., and I don't have
all those Action classes. I call these other classes controllers and they
are seperated by business functionality (e.g. AccountWebControl,ler,
MetadataWebController etc..).. The in turn access a web-neutral JDBC layer
(I don't use EJBs).
If anyone is interested in the code let me know.

Subject: Craig M. - Comments on "Minimizing Action class proliferation"
Craig,
Last week, there was a thread labelled: "Minimizing Action class
proliferation". I think you were on your brief "no list access" hiatus. :)
Below is the long-and-short of a proposed enhancement to Struts that could
optionally be used by developers if they are so inclined. The only piece
missing from this is a proposed change to the "action" XML elemen to include
a "handler" or "method" attribute. This would be used as the first parameter
to the "class.getMethod" call in the code below.
I won't regurgitate the whole thread here. I was just wondering if you had
any thoughts on this?
Thanks,
Donnie
[EMAIL PROTECTED] 03/07/01 10:05PM
Donnie,
How about this as an alternative. I have created a subclass of Action
called
StandardAction which uses reflection to invoke a method with the same name
as the "actions" path (defined in the struts-config.xml file). So all you
have to do is extend the Standard action and implement methods that
correspond to the paths that use it.
For example if you define three actions in your struts-config.xml file of
/saveOrder, /editOrder and /deleteOrder that all use a class OrderAction
which extends StandardAction and then create a OrderAction class as shown
below:
I hope this is of use.
Niall
--Example of StandardAction implementation---
public class OrderAction extends StandardAction{
public ActionForward saveOrder(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) {
}
public ActionForward editOrder(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) {
}
public ActionForward deleteOrder(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) {
}
}
---StandardAction Class---

public ActionForward perform(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) {
// Determine the method name to call (based on the path without the

String methodName = mapping.getPath().substring(1);
// Get the method with the same name as the path
Class cls = this.getClass();
Method method = null;
try {
method = cls.getMethod(methodName, new Class[] {ActionMapping.class,
ActionForm.class,
HttpServletRequest.class,
HttpServletResponse.class});
}
catch (NoSuchMethodException ex) {
servlet.log("Method "+methodName+" not found in class
"+this.toString());
}
// Invoke the Method
Object obj = null;
try {
obj = method.invoke(this, new Object[] {mapping, form, request,
response});
}

Fully decoupling the VIEW from the CONTROL
Given an action mapping with these attributes set: !-- Process a admin logon -- action path="/admin/logon" type="com.solers.portal.pcontrol.admin.LogonAction" name="logonForm" scope="request" validate="true" input="/admin/logonVue.jsp" forward name="success" path="/admin/mainMenu.jsp"/ /action and if additionally we could tell struts via the struts-config.xml that the input .jsp file was guranteed to only have ONE and only one action Then couldn't the action attribute in the FormTag become optional ? So this: html:form action="/logon" focus="username" would become this: html:form focus="username" which would FULLY uncouple the VIEW file from the CONTROL ?
Re: HTML paramter and its getter name
That is correct behavior. You MUST use property="companyID" and the getter method for it would be "getCompanyID()" As I just recently found out :-) you should use a capital letter *only* when followed by another capital letter. For example, if you had a "getAAA()" defined in your JavaBean, you'd use property="AAA", but if you had "getAaA()", you'd use property="aaA".

populate select box from formbean collection?
In my struts jsp page, I have a form. It's corresponding formbean is in
the request via my action class. My formbean has a property of type
collection that I would like to use to populate a select box. I have done
it a couple of ways, but it's real messy.
Does anybody have a more elegant solution? Both ways below work. but ugh!
Thanks!
%
//get the formbean out of request
com.healthgauge.UserForm uf =
(com.healthgauge.UserForm)request.getAttribute("userForm");
//get the collection and stuff in pageContext
pageContext.setAttribute("companies",uf.getCompanies());
%
html:select property="companyId"
html:options collection="companies" property="id"
labelProperty="companyName"/
/html:select
vs.
html:select property="companyId"
logic:iterate id="company" name="userForm" property="companies"
option value="bean:write name="company" property="id" filter="true"/"
bean:write name="company" property="companyName" filter="true"/
/logic:iterate

Re: populate select box from formbean collection?
The scope value is optional.
bean:define id="companies" name="userForm"
property="companies" scope="request"/
html:select property="companyId"
html:options collection="companies" property="id"
