RE: POST and GET method
Hi, Typically in the past when I have written my own controller servlets, I delegate from the doPost doGet methods to a process() method much like the Struts ActionServlet. The difference however is that the method signature for my process method includes a boolean to indicate whether or not the request originated as a GET or POST: public void process(HttpServletRequest req, HttpServletResponse res, boolean isPost) ... This way the framework doesnot hide that info from the user. Maybe a future release of struts can incorporate this simple change?

RE: POST and GET method
The current ActionServletpasses both doGet() and doPost()to process(request, response). if you want your entire application to handle doGet() with an error.jsp, ActionServlet is a good place to do so (assuming each webapp get its own ActionServlet). If you want to handle them per Action basis,you can find out HttpMethod with request.getMethod(),the request object is passed to Action.perform() by ActionServlet. -Original Message-From: Spencer Smith [mailto:[EMAIL PROTECTED]]Sent: Thursday, March 01, 2001 8:35 AMTo: [EMAIL PROTECTED]Subject: Re: POST and GET method That's a good question.

Re: struts and XSL
[EMAIL PROTECTED] wrote: There are many competing technologies to embrace the Model 2 pattern. I get the feeling that XML/XSL and Struts are mutually exclusive. Is this a valid concern ?? I'm not sure that they are mutually exclusive, but there is a choice you ned to make for the "outermost" controlling architecture for your web application. If your application is primarily content publishing, with data based primarly in XML, you owe it to yourself to consider a framework like Cocoon, which is aimed at precisely this type of environment. That doesn't prohibit you from using the Struts custom tag library (if your presentation is in JSP pages), but you probably will not need the Struts controller environment. If your application is primarily a dynamic business app, you owe it to yourself to consider the controller framework inside Struts. This doesn't prohibit you from using XML, XSLT, and XSP -- you can still use them to create portions of the content of your pages -- but you probably will not need the Cocoon site map capabilities.

I added a depends attribute to the validation definitions so you could say that checking for an integer shouldn't be done until required validations are done. It's probably needs some work on the logic, but it seems to be working on the basics. Also a number of objects could be created and cached somewhere.

When you iterate over a Hashtable (or any other implementation of the Map interface),
the object get for the "id" variable is actually an implementation of
the "Map.Entry" class, not the class of the value of the bean. From this "Map.Entry"
instance, however, you can easily get to the real information:
bean:write name="supplier" property="value.seq_nbr" scope="page"/
This works because a MapEntry has two properties -- key and value -- so we are using
the nested property syntax to effectively call getValue().getSeq_nbr().

Re: Is the struts example itself is multi-thread safe?
Thank you, Craig for clear "picture". One Q. to be sure that all OK. What about servlet.log file? Several action threads will need to have an access to it.,... Maya "Craig R. McClanahan" wrote: Maya Muchnik wrote: Hi, In "A Walking Tour of the Struts App", the author has mentioned that "There is only one object for each action (URI), so your action objects must be multi-thread safe". Is the example itself is multi-thread safe? I am asking this, because are several actions here, but not one of them use "synchronized" statement. Maybe I am missing something... Possibly. Thread-safety is a general term meaning "even if two or more users are calling methods in my class *simultaneously*, nothing will get messed up. In the case of Action classes in the example application, they are indeed thread safe. Why? Primarily because they use no instance variables -- only local variables within the perform() method. If the example used instance variables, then there would be only one copy of those variables (because Struts creates only one instance of your Action). However, local variables appear on the stack for each request thread that is happening simultaneously. Any single thread can only see its own copy of these variables, so there is no possibility for contention. One place you will see synchronization in the example app is when adding to the pseudo-database. Consider what would happen if two users logged on with the same id, and both proceeded to add a new subscription at exactly the same moment. You would have two attempts to modify the database (which, because it is a servlet context attribute, is visible to all request processing threads), so you need to synchronize here. The other place that you commonly need to synchronize is when you are modifying session attributes (read-only access is generally safe without locking). It is surprisingly easy to have multiple requests active at the same time for the same session -- for example: * In a framed presentation, the browser will often issue requests for more than one frame at the same time, all with the same session id. * Users might open multiple browser windows, which (in many circumstances) causes each window to be part of the same session. * The user can submit a long running transaction, press STOP (which the server does not know about), and then start something else. THANKS in advance. Maya Craig

I believe you want the bean to be SupplierBean rather than Supplier. Your

When you iterate over a Hashtable (or any other implementation of

actually an implementation of

From this "Map.Entry" instance, however, you can easily get to

This works because a MapEntry has two properties -- key and value

Re: Why should you call JSP pages directly?
One way, as I know, is to put all jsp, except index.jsp (or similar start up) under a protected directory. For Tomcat the secure directory is setup in web.xml (see web.xml for webapps/example, directory is example/jsp/security/protected). See also Tomcat instruction (I need refresh my memory myself).

HTTPClient vs java.net.URLConnection
Hi, Does anyone use HTTPClient? What do you think about it? I have got this link several minutes ago. As its document said, in HTTPClient you can set timeout for response, pipelining of request. Source code is available. It includes the source code for parsing the multiPartRequest. HTTPClient can find at: http://www.innovation.ch/java/HTTPClient/
Re: Drop-down list
Add the attribute to your tag like so:
html:select ... multiple="true" ...
and make sure the corresponding property in your form bean is an array of
values.
See the docs for more details:

Bug in handling multiple values in multipart forms
Hi,
I've encountered a bug in handling multipart requests.
(last nightly build 20010224)
If a form is sent with enctype="multipart/form-data" the multiple values
(e.g. select multiple...) aren't set correctly. In the
DiskMultipartRequestHandler the values are stored in a Hashtable thus only
the last one of the values is set in the Form.
A possible solution:
old DiskMultiPartRequestHandler.java @ line 71
if (!element.isFile())
textElements.put(element.getName(), element.getValue());
allElements.put(element.getName(), element.getValue());
}
---
new DiskMultiPartRequestHandler.java
if (!element.isFile())
String name = element.getName();
String value = element.getValue();
Object oldValue = textElements.get(name);
if (oldValue != null) {
String[] oldValues = new String[1];
try {
oldValues = (String[]) oldValue;
} catch (ClassCastException e) {
oldValues[0] = (String) oldValue;
}
int length = oldValues.length;
String[] newValue = new String[length + 1];
for (int i = 0; i length; i++) {
newValue[i] = oldValues[i];
}
newValue[length] = value;
textElements.put(name, newValue);
allElements.put(name, newValue);
} else {

allElements.put(name, value);

Re: HTTPClient vs java.net.URLConnection
I've just recently started using HTTPClient with struts on the webserver and it seems pretty reliable. Although I haven't really pushed it much, it was easy to get up and running and I haven't found any real issues with it. (I think I had one issue but can't remember what it was...I guess it wasn't that bad.) Also, the feature set seemed to be well thought out and organized. As an example, HTTPClient made it easy to mess with cookies using the provided methods. Anyways, some of my next tasks should be to start pushing it a bit harder. We'll have to see what happens then. -Paul Mailing-List: contact [EMAIL PROTECTED]; run by ezmlm list-help: mailto:[EMAIL PROTECTED] list-unsubscribe: mailto:[EMAIL PROTECTED] list-post: mailto:[EMAIL PROTECTED] Delivered-To: mailing list [EMAIL PROTECTED] From: Maya Muchnik [EMAIL PROTECTED] X-Accept-Language: en MIME-Version: 1.0 To: [EMAIL PROTECTED] Subject: HTTPClient vs java.net.URLConnection Content-Transfer-Encoding: 7bit X-Spam-Rating: h31.sny.collab.net 1.6.2 0/1000/N Hi, Does anyone use HTTPClient?

Add the attribute to your tag like so:

and make sure the corresponding property in your form bean is an array of
values.
See the docs for more details:

Mary, The problem is the initial FRAMESET sent to the browser forces the browser to initiate seperate requests to fill in the frames of the page.

Re: Why should you call JSP pages directly?
Maya Muchnik wrote: One way, as I know, is to put all jsp, except index.jsp (or similar start up) under a protected directory. For Tomcat the secure directory is setup in web.xml (see web.xml for webapps/example, directory is example/jsp/security/protected). See also Tomcat instruction (I need refresh my memory myself). Using container-managed security in this way is indeed portable. A second portable mechanism (assuming that your container works correctly per the servlet spec) is to put your JSP pages under WEB-INF. This works because the servlet container is prohibited from allowing a client to access these JSP pages directly -- but it is entirely legal to do a RequestDispatcher.include() or RequestDispatcher.forward() call to access them, as Struts does when you forward to the appropriate page.

I have wasted so much time trying to get this to work and all that was missing in my

When you iterate over a Hashtable (or any other implementation of the Map interface),
the object get for the "id" variable is actually an implementation of
the "Map.Entry" class, not the class of the value of the bean. From this "Map.Entry"
instance, however, you can easily get to the real information:
bean:write name="supplier" property="value.seq_nbr" scope="page"/
This works because a MapEntry has two properties -- key and value -- so we are using
the nested property syntax to effectively call getValue().getSeq_nbr().

One approach to this is to configure the URI of your login page as the "welcome" page for the app, using the welcome-file element in web.xml. * What about bookmarks? You have to be ready for the fact that users are going to *try* this, even if you do not want them to. Alternatives have been presented to protect JSP pages from this kind of access. * If you are switching from one view to another view (with no model manipulation), I cannot see that much difficulty in linking from one JSP page directly to another, but this is not particularly common. In a servlet 2.3 environment, you will be able to enforce things like going through the controller using the Filter facility. Until then, though, we have to deal with issues like those listed above.

I was considering an approach where coders wrote validation code in Java

That is then mapped to the form field in an xml file somewhere.
Struts, however could ship all the standard validations (such as Strings
to ints)
together.
It is something I have not given much thought to yet, but would be
interested in
exploring further.
Beyond the thinking expressed so far on this thread, I've had two
additional ideas
for functionality that should be included here:
* Optional generation of client-side JavaScript code to do the kinds
of validations that make sense (required fields, number formats, etc.)
closer to the user.
* The JavaBeans spec includes the concept of a PropertyEditor, which
lets you define a custom conversion between String and a bean data type.
JSP 1.2 supports this when doing attribute conversions -- we should look
at whether it can help us in the conversion/validation arena as well.

nope, not that strange.
if you viewed the source of your page, you should be able to see your

The container will only complain about undefined tags if there is a .tld
defined with
a prefix at the top of the page (ie the struts-logic tags). Otherwise it

JUNIT and Struts
We use a JUnit extension (HttpUnit) to do all of our functional testing. We
can effectively 'fake' the user submitting a form, and check for page
results. We've added some code into a base test class so that we can use
methods like assertPageText("xyz") or assertPageError
("struts.resources.key").
This works very well.
