how to get the version of struts during runtime
hi, i would need to check the version of struts running during runtime, to be more specific when my derived action servlet runs through its init method (derived from ActionServlet of course). reason is, if the minor version has changed, a warning should be written to the logs; if a major change of the version happened, my action servlet will refuse to start until somebody checked the code of the servlet and made sure that it's running with the new version. any ideas? kr, guenther -- Günther Wieser creative-it Guglgasse 6/1/11/1 A-1110 Wien Austria http://www.creative-it.com 2 Dinge sind unendlich: Das Universum und die Dummheit der Menschheit, aber beim Universum bin ich mir nicht so ganz sicher.

Subject: html:cancel question
I have a function to disable buttons onsubmit because I don't want the user
to keep clicking, especially for long running actions. However, this seems
to interfere when the button is an html:cancel, which is a type of submit.
It seems to ignore the correct behavior of cancelling and attempts to do a
validated submit. What do I need to do to disable buttons AND get cancel to
work properly?
function disable(form)
{
var buttons = form.getElementsByTagName(input);
for (i = 0; i buttons.length; i++) {
if (buttons[i].type == button || buttons[i].type == reset ||
buttons[i].type == submit) {
buttons[i].disabled = true;
}
}
return true;

RESEND: RE: Load message resources from DB???
resend because i didn't receive it on the list. sorry if this comes to you
for the second time.
hi,
as it isn't possible to send zip files to the list, i need to copy and paste
the most important things out of our implementation:
the factory is simple:
public class DBPropertyMessageResourcesFactory extends
MessageResourcesFactory {
/* (non-Javadoc)
* @see
org.apache.struts.util.MessageResourcesFactory#createResources(java.lang.Str
ing)
*/
public MessageResources createResources(String config) {
return new DBPropertyMessageResources(this, config,
this.returnNull);
}
}
also, the DBMessageResources class is quite simple, here's the most
important method:
public String getMessage(Locale locale, String key) {
String result = DBPropertyMessageService.getMessage(locale, key,
returnNull);
// we need to flush the cache of the super class MessageResource as
we want to have real // dynamic data here (no caches
// except the one in DBPropertyMessageService)
formats.clear();
return result;
}
so the REAL thing is happening in DBPropertyMessageService, and this class
just loads everything at startup (static constructor) into a hashmap. we
have implemented the service class in such way that it's the one and only
point where changes to a property have to go. this allows us to change
values during runtime, and even add new key value pairs during runtime
without reloading from the db.
it's also easy to implement a feature that reloads the db entries ater a
given period of time.
kr,
guenther

RE: download finished
how do you send the file to the user? is it going through a servlet, or is it just normal file download through e.g. apache? in the later case, it will get complicated easy solution is to serve the file through a servlet, and if your servlet doesn't get any ioexception during sending the file, and exits normally from eg. doGet() or doPost(), than the file should've been received by the user's browser. but there is still a small chance that the user didn't get it if there is a proxy inbetween, which gets the whole file even if the user cancels the download. but normaly that shouldn't happen as most proxies do not cache files, expecially if you set the cache http headers correctly. kr, guenther -- Günther Wieser creative-it Guglgasse 6/1/11/1 A-1110 Wien Austria http://www.creative-it.com -Original Message- From: Kelly C.

RE: session and request scope
as long as you don't have a clustered environment or session persistence enabled in your servlet container, there shouldn't be much difference in adding an object to a session or request. but it doesn't make sense to put it in session scope if you don't use it is session scope, but only in request scope. this could make your life harder than you want it to be (e.g. if you forget to delete such objects). this leads to one issue for session scope: if you store things in session, you HAVE TO REMOVE them as soon as you don't need them anymore, otherwise you can run out of memory because these objects won't be garbage collected. and usually it's very hard to make sure that your web app DEFINITELY reaches the point of deleting things from a session (think about a user just pressing back or going to a different page before hitting your remove page). of course, everything will be dumped when the session expires, but if you have a lot of users in your web app and they stay for a long time, the memory consuption can become significant if you have a lot of session objects. kr, guenther -Original Message- From: wo_shi_ni_ba_ba [mailto:[EMAIL PROTECTED] Sent: Thursday, March 10, 2005 10:52 PM To: user@struts.apache.org Subject: session and request scope In terms of performance, does storing an attribute into the session cost more than storing it into the request? how significant is the overhead? __ Do you Yahoo!?

RE: Struts DB Access :: Best Practices
i prefer to use OJB for persistence, because i like the approach of coming from the object world and define the mapping to the database, while hibernate (and others) tend to come from the database and help you generate classes. OJB is very easy to use, and you won't see anything related like PK-FK or id within your java code which makes it easy to read and has nothing database related in it. but if you have the need to tune performance etc. OJB gives you access to everything, inluding using stored procedures. kr, guenther -- Günther Wieser creative-it Guglgasse 6/1/11/1 A-1110 Wien Austria http://www.creative-it.com -Original Message- From: karthikeyan balasubramanian [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 09, 2005 9:19 AM To: user@struts.apache.org Subject: Struts DB Access :: Best Practices Hi all, I am planning to use Tomcat/Struts/MySQL in my project.

RE: session.invaludate(); not working in LogoffAction
i prefer to write my own RequestProcessor which does all the checking and
handling in case of user not logged in.
and even more preferable is to implement J2EE security which was suprisingly
simple (at least for Resin).
i wrote an example for the request processor stuff a few days ago here in
the list, here it is again:
--
public class MyRequestProcessor extends TilesRequestProcessor {
public void process(HttpServletRequest req, HttpServletResponse res)
throws IOException, ServletException {
HttpSession session = req.getSession();
String path = super.processPath(req, res);
String url = req.getRequestURL().toString();
String queryString = req.getQueryString();
// the next lines are there to allow deep linking
// we store the url that has been requested for future use
if ((queryString!=null) (!.equals(queryString))) {
url = url + ? + queryString;
}
if (session.getAttribute(Constants.SESSION_LOGIN_REFER_KEY)
== null) {
if (url != null) {
session.setAttribute(Constants.SESSION_LOGIN_REFER_KEY, url);
}
else {
//TODO: get main URL from property
session.setAttribute(Constants.SESSION_LOGIN_REFER_KEY,
http://localhost:8080/WebCreator/index.do;);
}
}
// no comes the important stuff
if (!checkForRealm(session)) {
if (!/login.equals(path)) {
super.doForward(/login.do, req, res);
}
}
super.process(req, res);
}
protected boolean checkForRealm(HttpSession session)
throws ServletException, IOException {
if (session.getAttribute(Constants.SESSION_USER_KEY) != null
) {
return true;
}
else {
return false;
}
}
}
so what it does is:
- get the current requested url for further reference and stores it in the
session if an atrribute with the same key does not exist (see deep linking
below)
- then it checks the session for the realm (that is the attribute that you
use to say the user is logged in)
- if it does not exist and if the request didn't go to /login.do, it
forwards the request to the action /login.do (which is a simple html with
username/password field)
- if it exists it redirects to the super class to process the request as
usual
- you need to implement the checkRealm() method with whatever you need to
check, my example is really simple but very common
with extending TileRequestProcessor (don't care that i extend
TilesRequestProcessor, you can extend the standard request processor the
same way) and adding the lines in struts-config.xml, each request that hits
the struts action servlet will go through MyRequestProcessor BEFORE the
typical struts tasks (action, form beans filling, etc) start. so this is the
right place to check security, authorization and authentication.
regarding deep linking: i want my customers to be able to store a bookmark
that points deep into the system. when they request this bookmark, they of
course need to login first. so i store the requested url in the session, and
if the login is successfull, i send a redirect to the browser to disply the
page the user requested with his bookmark.
this is done by sending a meta refresh command in the head of the resulting
login ok page, with the url containing the session attribute that has been
store with session.setAttribute(Constants.SESSION_LOGIN_REFER_KEY, url)
hope that helps, feel free to ask more if something is unclear.

RE: html:form complains of bean missing
hi scott,
well, i'll try my best.
here's the code from the execute method of MyRequestProcessor (that's the
one included in the struts-config.xml):
public class MyRequestProcessor extends TilesRequestProcessor {
public void process(HttpServletRequest req, HttpServletResponse res)
throws IOException, ServletException {
HttpSession session = req.getSession();
String path = super.processPath(req, res);
String url = req.getRequestURL().toString();
String queryString = req.getQueryString();
// the next lines are there to allow deep linking
// we store the url that has been requested for future use
if ((queryString!=null) (!.equals(queryString))) {
url = url + ? + queryString;
}
if (session.getAttribute(Constants.SESSION_LOGIN_REFER_KEY)
== null) {
if (url != null) {
session.setAttribute(Constants.SESSION_LOGIN_REFER_KEY, url);
}
else {
//TODO: get main URL from property

}
}
// no comes the important stuff
if (!checkForRealm(session)) {
if (!/login.equals(path)) {

throws ServletException, IOException {

of pages together. But as far as handling the session expires, etc, I do not
completely understand how this is accomplished.
What I have today, is a extended Action class which I can call a method eg:
if (obj.isLoggedIn()) { type of method. So each of my pages has to go to
the action servlet.
Anyway, if you could show me how you are handling this, or be a litle more
precise that would really help me out.
I sincerely appreciate your time,
Scott

AW: Tooltips in Struts
you can use the title attribute of the span tag like this way:
span class=reportTooltip title=yout tooltip textyour text or your
elements/span
and with using CSS you can set up the tooltip behaviour:
.reportTooltip {
COLOR: gray;
CURSOR: help;
TEXT-DECORATION: none;
}
if you use cursor: help the cursor in the browser will change to a cursor
plus question mark when the user moves over any element that has a tooltip,
showing the user that a tooltip exists.

Yes, sort of. If you simply want little yellow popups when your mouse
hovers over an image, use the title attribute for that image. You
can do the same for just about anything else, but it may require being
creative with some div tags and such.

RE: html:form complains of bean missing
hi if you want a single point where you can check if a user is logged in or not, you can do something like the following: create a class MyRequestProcessor extends TilesRequestProcessor (in this case it is because i use tiles) and implement the process() method. within this method check for the login var that you e.g. put into the session. in the struts-config.xml add controller processorClass=com.creative_it.webcreator.strutsext.MyRequestProcessor / and everythings fine. what you need to do in the MyReqestProcessor class is to exclude all URLs from checking that are used for e.g. the login form, or an error message in case something went wrong. if you want to be very nice to your users, store the URL that the user requested in the session, than redirect to the login form, and if everything went fine with the login, send him to the page that he/she originally requested. if you want the code for this, let me know, i can provide it. kr, guenther -Original Message- From: Scott Purcell [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 01, 2005 7:17 PM To: user@struts.apache.org Subject: html:form complains of bean missing First off, as I am learning Struts I just wanted to thank those, for bearing with my learning curve and helping out so far. Here is the issue: I want to pass all my forms, even forms without params to the com.skp.action.LoginAction action class, because this class handles the isLoggedIn issue through a subclass of Action. Anyway, I have a jsp page that has no params, so I have no bean to collect user data, so I configured my action like so: action path=/mainAdmin type=com.skp.action.LoginAction forward name=Success path=/jsp/admin/main.jsp redirect=true/ /action Anyway, I just want to always use the LoginAction as a Front Controller to my web app, and catch the status of logged-in etc. This works well, but I have to use conventional html code and not the html:form tag: works: !-- form name=foo action=/uniquepear/action/mainAdmin method=POST -- does not work: html:form action=mainAdmin When I use the above I get this error in the browser: javax.servlet.ServletException: Cannot retrieve definition for form bean null at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImp l.java:495) at org.apache.jsp.main_jsp._jspService(main_jsp.java:175) But I have no reason to have a bean for this action.

RE: Struts and EJB integration question?
i for one suggest to put it in a delegate class (maybe something with static methods), something you would call a service, that gives you access to your ejb stuff. putting it directly into the action class is not recommended, the action class should be seen as the connection between your business layer and the view, so it should ust delegate, not process anything. as mentioned, this is my private opinion and i'm sure there are may different opinions out there kr, guenther -Original Message- From: leonnewsgroup [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 01, 2005 10:40 PM To: Struts Users Mailing List Subject: Struts and EJB integration question?

caching of message resources when using bean:message tag
hi, we are using struts version 1.2.4 and we implemented our own MessageResources and MessageResourceFactory. we needed to have a database based system for managing message resources for different locales so that we can change valued on the fly without the need to restart the app. these implementation work quite well, but we found one issue when using bean:message key=whatever/: it seems that the message with the key whatever gets cached somewhere. the first call to this bean with key=whatever results in a getMessage() call to our implementation of MessageResources. the message gets delivered and inserted into the JSP. but all further calls to the message tag do NOT query MessageResources.getMessage(), so we assume that the message value is cached somewhere. what we see from the source code of the message tag is that TagUtils.message() is called. so far we haven't found anything that caches in TagUtils. and there's no caching in the message tag . anyone an idea where the caching takes place? am i missing something fundamentally when i assume that it's possible (with my own implementation of MessageResources) to change message resources in struts dynamically during runtime? kr, guenther

There were license issues so I had to host them elsewhere (same link above) but I haven't released these as of yet. That's on my todo list ;) The workaround for Struts 1.1 and 1.2.x is to clear the hashmap of formatted messages. Look at org.apache.struts.util.MessageResources#getMessage(Locale locale, String key, Object args[]). In that method you'll see where if the formatted message (param replacement already done) is found, then that is returned. That certainly is a nice way to speed up things, but the impl fails to make that configurable, so you are just stuck with it :( My impl simply does formats.clear() on each call to getMessage(), so, in effect, unless the very next call to your getMessage() is asking for the last one you just gave it, the cache is (basically) disabled.
