validation
I have a jsp page that has input fields for personal information, so i made a PersonalInfoForm with all the setters and getters and a validate method. On this jsp i also have a drop down list that gets created by an array of beans: I pass "ethncityArray", which is an array of TranslateItem beans, to this page via the request. The problem i have is that when the validate method is called when i hit submit and an error occurs, it goes back to the jsp but the jsp can no longer find "ethnicityArray". Subsequently an error is thrown. Does anyone know how i can fix this, aside from putting it in the session? cameron

As the documentation indicates, that is the only legal use for . But it's impossible to know if this is the problem or not, unless you show us the entire page. As a side comment, the normal JavaBeans convention is that property names start with lower case letters, so you might want to change "Server" to "server".

RE: Delegating the request processing to an Action class
I would not be too concerned about the performance impact of Oleg's suggested approach. After all, the controller servlet is just going to do a RequestDispatcher.forward() back to itself, which has no more performance impact than the usual RequestDispatcher.forward() used to transfer control to a JSP page in the usual case.

In my struts-config.xml, i have CourseList as the form associated with the
Action to submit. I also put a for CourseList in the jsp. But
it still doesn't work. I'll keep trying.
Do you know if there is a way to associate mulitple forms with a single
action in the struts-config.xml file i.e.

Re: Is there any way to start struts tag in heade.jsp and endit in f ooter.jsp??
I'm not sure I understand. If all you have at the top is the start of a logic tag, and all you have at the end is the end of that tag, why would you want to pull those out into separate files? Or am I not understanding what you want to do? In any case, the whole tag has to be in a single JSP page. If you really need to put them in separate files, you can use the include directive to include them at compile time, like this: <%@ include file="header.inc" %> You can't use the include tag to do this dynamically, though, because each JSP page has to be compiled into its own servlet. Breaking the tag across pages leaves you with illegal syntax for those servlets. -- Martin Cooper - Original Message - From: "Vaibhav Patil" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, July 06, 2001 5:18 AM Subject: Is there any way to start struts tag in heade.jsp and end it in f ooter.jsp?? > Hello, > I have a common part to be put into all files.

Re: More than one resource bundles.
The 'bundle' attribute specifies the name of the (application, or servlet context) attribute under which the loaded message resources are used. To use a second bundle, you will have to load it yourself and store it as an attribute, so that your JSPs can access it. Probably the best way to load additional bundles is by extending ActionServlet and overriding one of the init* methods. (The initApplication method is where Struts loads the 'application' bundle.) That way, the bundle will always be loaded before any of your Actions are processed. Hope this helps. -- Martin Cooper - Original Message - From: "Jain, Shipra" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, July 06, 2001 3:01 PM Subject: More than one resource bundles. > Hi > > I am a new user of Struts.

Re: Bean Introspection and tag
What you are seeing is the correct behaviour. I think the piece of the puzzle you are missing is that, in the part of the JavaBeans spec you are looking at, it says: "Thus when we extract a property or event name *from the middle of an existing Java name*, we normally convert the first character to lower case." For example, when extracting the property name from a method named 'getLastName', the first character is converted to lower case, resulting in the property name 'lastName'. The thing that is a bit confusing is that the JavaBeans spec talks about how to obtain the property name from a method (getter or setter) name, whereas we (at least you and I, anyway!) tend to think of the process the other way around, as in "what is the getter name for this property?".

No it just does a single parameter, for multiple params you need to use name

Re: Where to do the init() for Actions?
You can override the setServlet() method to do this.

RE: indexed properties
Cameron,
Does the Action that is run when you submit the form have "CourseList"
associated with it?
If that sorts out the issue with not finding "CourseList" then I think
"CourseList" should look like this:
public final class CourseList extends ActionForm
{
private ArrayList courseList = new ArrayList(6);
public ArrayList getCourseList() {
return(this.courseList);
}
public void setCourseList(ArrayList courseList) {
this.courseList = courseList;
}
public CourseForm getCourseList(int index) {
return (CourseForm)courseList.get(index);
}
}
Then in your "CourseForm" bean you need setters for all the properties (i.e.
crstitle, crsdept, crshrs, crsnum).

I need some help on using the indexed properties for html:text option.
I've implemented Dave Hay's modification and can get the input boxes to show
up using the iterate tag.
<%= courseNumber++ %>
This is what my CourseList bean looks like:
public final class CourseList extends ActionForm
{
private ArrayList courseList = new ArrayList(6);
public ArrayList getCourseList() {
return(this.courseList);
}
public void setCourseList(ArrayList courseList) {
this.courseList = courseList;
}
public CourseForm getCourseForm(int index) {
return (CourseForm)courseList.get(index);
}
public void setCourseForm(int index, CourseForm course) {
this.courseList.add(index, course);
}
}
The problem i have is that when i try to submit the information and try to
access CourseList.getCourseList(), it bombs and says CourseList cannot be
found. The scope is request. I tried putting it in the session and can
access it that way but it doesn't have the changes that were made on the
form. Anybody know what i'm doing wrong?
thanks,
cameron
RE: No Need To Localize
The tag uses RequestUtils to find a message - this looks for a locale stored in session scope under the key "Action.LOCALE_KEY". The usual way for the "locale" to be stored under this key is using the tag - if you dont use that, then struts will always use the default locale. But...if you are sure you never want an internationalized app then why don't you do away with resource bundles altogether - just put all your messages directly in the jsps?

RE: session form beans
It doesn't - they will go when the session ends, or you have to explicitly remove them.

RE: Where to do the init() for Actions?
ActionServlet is a "plain Servlet" you can extend it and override the init() method (make sure you call super.init(), so that the standard Struts init(0 stuff is done.

Re: MultipartRequest and oreilly's servlet package
By the time your perform() method is called, the input stream has already
been consumed by the Struts multipart handler, so there's nothing left for
the O'Reilly one to read. You'll need to disable the Struts multipart
handler first.
Unfortunately, there isn't a good way to disable the Struts multipart
handler. Although you can specify an alternative handler as an init-param,
that has to implement the MultipartRequestHandler interface, and there's no
way to specify "no handler".
To work around this, you should be able to call setMultipartClass() in
ActionServlet, passing it null for the class name. (I haven't tried this,
but it should work.) The best time to do this would be at initialization
time, which means you would have to extend ActionServlet and override one of
the init* methods (perhaps initUpload itself).
I recently took a different approach to work around some problems with the
Struts multipart handler. Since I already had a bunch of code that was built
around the Struts mechanism, I didn't want to have to change it all, so I
wrote my own implementation of MultipartRequestHandler. I'm using Resin as
my container, which has multipart support, so I layered my handler on top of
Resin's approach and just dropped in my handler as a replacement for the
Struts handler. It seems to work well.
Hope this helps.

No Need To Localize
We are developing a web application using struts which will not need to be internationalized. Is there some way to tell struts NOT to look for and manipulate Locale's? In other words, there will always be one and only one resource bundle for tha application. Any pointer is appreciated. Thanks, David
MultipartRequest and oreilly's servlet package
Hi!
I was trying to implement an upload feature using oreilly's
com.oreilly.servlet package. http://www.servlets.com/cos/
(...and NOT using the build-in functions in struts)
The oreilly stuff works great, but when I combine struts and
the oreilly classes I'm getting an IOException
(Corrupt form data: premature ending) in the oreilly class.
This seems strange to me, does struts somehow "corrupts"
the HttpServletRequest so that it cannot be accessed by
oreilly's MultipartRequest class?

public ActionForward perform(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException
{
try {
MultipartRequest multi =
new MultipartRequest(request, ".", 10*1024*1024); // 10MB

RE: JavaBeans creation
I would suggest using JBuilder Foundation because it is free. It has the features you are looking for. -Original Message- From: Vikramjit Singh [mailto:[EMAIL PROTECTED]] Sent: Saturday, July 07, 2001 12:32 AM To: '[EMAIL PROTECTED]' Subject: RE: JavaBeans creation hi why not trying to use JDeveloper by Oracle. it is a very good IDE and it gives you the setter and getter methods ready made.

Re: Struts Templates Example in VAJ 3.5.3/WTE - Problem
Cedric, Jon, Downloaded a more recent version of Struts (30 June 2001), added flush='true', to template:get statements and Voila !, that does solve the template rendering problem, Thanks, Martin
