How to detect that session has expired ?
Hi All, How can I detect that session has expired and so throw the user out of system after showing him a message that Your session has expired. Please login again. Thanks, BS - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: How to detect that session has expired ?
When a session restarts, its context is empty, so all objects stored in the session context have disappeared. To detect if a session has restarted, you need first to store an object in the session context, then each time you need to know if the session has restarted, you test its presence in the context. If it is not there anymore, then the session has restarted.

RE: Link-to-action?
Hi In our current project we are using an adapted version of the LinkXTag class provided with the struts example application. Check out this class and I hope it is what you need. Kind regards Dennis Hunziker -Original Message- From: Theodosios Paschalidis [mailto:[EMAIL PROTECTED] Sent: Sonntag, 7. Dezember 2003 00:10 To: [EMAIL PROTECTED] Subject: Link-to-action? Hi all, I am a new struts user utilizing it for my uni project. I have reached a point that I do not know how to handle the struts way and am really stuck! I spent a lot time on this and I would be grateful for any further info! I am dynamically producing some search results. I will be turning them into links and I want to pass a parameter. Is it possible that a user clicking on a link can trigger an action? eg having something like a href=DisplayItem.do?ItemId=223 Using JSPs would be easy to do invoking the appropriate method directly the above way. Using servlets I could just do String itemId=request.getParameter(Itemid). Since an ActionClass is a servlet could I achieve the same using the Form as a transfer object for the ID property? If this cannot be done using the struts sequence (Form-Action) then maybe it will be easier forwarding to a JSP? Doing that though will require me using a scriptlet to retrieve the object of interest :( Any better way? (because my Items are nested I am trying to do it through an Action) In a nutshell: 1) I display a collection 2) I want to somehow select the item that the user clicked, for detailed description Any help will be really appreciated!

How to refer/declare to ImageButtonBean within a JSP
Hi, I have a need to define multiple Image Input Button within an Iterate tag and I am experimenting with the use of ImageButtonBean. I would like to know that having defined the ImageButtonBean, how does one declare it within the html:img tag. An example would be great. Secondly, how does one resolve which particular button from those generated by the enclosing Iterate tag was actually clicked. I would highly appreciate your input in this regard TIA Shantanu

RE: How to detect that session has expired ?
Seems this is not supported by many containers yet(J2EE 1.4). You could use a filter to check for session expiry but what if it expires after it passes the filter. Then each JSP should have a check in the beginning.

RE: from Action to Facade: simple attributes or Business Objects
The philosphy is that the Actions (controller) move bean properties
from form bean(s) into business beans, and pass the business bean into a
business object to perform an operation. I.e., the action should
contain all of (and only) the web-specific portion of the application.
I.e., the latter case in your example. Think about what happens if you
add a property? How many places do you need to change it? One less (at
least) in the patter case. You can (typically) use BeanUtils.populate()
do move all properties in one fell swoop.

RE: How to detect that session has expired ?
You ought not to refer directly to any jsp pages anyway. Always refer to an action which forwards to your jsp. Then you can put your JSPs inside WEB-INF if you want (insures they can never be directly accessed) and you never have to add any tag(s) to check for valid user. As Ed points out, Inheritance is your friend. Get to know him, and his cousin, Poly. Poly Morphism.

Tks for the reply Tim.
I now see the advantages of my latter case.
But being my form bean a DynaActionForm, can I still use
BeanUtils.populate()??
If not, what would be the alternative?

I am using MappingDispatchAction and am attempting to pre-populate
a DynaValidatorForm in a setup action. Without validation, the

again reaches my submit and past my validate, but fails to show
back in the redisplayed form in error.
I have looked through the forums and docs and know it has been
covered. I am seeking an extra eye because I can't seem to figure
out what is going wrong. If you don't mind can you take a quick
look. I have tried many variations and think it is something

Maps within Beans (was Stupid Bean Tricks)
This example relates how to _implement_ things in your own taglibs. It doesn't mention Maps at all (the part I'm being befuddled by). It's not even specific to struts. Actually, all I need is a reference on usage of the struts taglibs beyond the foo.bar.baz example. I want to see how one can refer to Maps contained in beans like Martin explained: bean:message name=user property=en.message/ I have to admit, I found this confusing also because in my User object (session key as user) there would be a map of UserData objects. The above example doesn't mention userdata at all, so I'm guessing Martin meant this: bean:message name=user property=en.UserData.message/ But in the interest of saving bandwidth, just the reference on how to get to maps within beans. -Original Message- From: Martin Gainty [mailto:[EMAIL PROTECTED] Sent: Sunday, December 07, 2003 10:59 PM To: Struts Users Mailing List; [EMAIL PROTECTED] Subject: Re: Stupid Bean tricks a complete example on how to use this concept is located at http://www.orionserver.com/tutorials/taglibs/8.html viel Glueck, Martin - Original Message - From: Joe Hertz [EMAIL PROTECTED] To: 'Struts Users Mailing List' [EMAIL PROTECTED] Sent: Sunday, December 07, 2003 5:58 PM Subject: RE: Stupid Bean tricks Martin- Can you point me to the correct docs for how this works?

the way, I do not use 'request' to retrieve the value

[OT] Exception handling in a J2EE project.
Hi All, What is the best Hierarcy (framework) for handling exceptions in a J2EE project. I am thinking of some roughly the following Hierarcy consisting broadly of three categories : + MyApplicationException extends Exception ( For handling bussiness exceptions.) - InsufficientBalanceException - InvalidPasswordException - etc. + MySystemException extends RuntimeException (Non bussiness exception, exception due to System problems) + MyEJBException extends EJBException (Not too sure if this is required) My question is : 1. Is this approach correct ? 2. My application flow consists of ActionClass calls BussinessDelegate calls SessionBean calls DAO and ActionClass calls BussinessDelegate calls SessionBean calls EntityBeans How should the exception for take place. Should it be something like this: DAO throws some ApplicationException ... caught by SessionBean thrown as some EJBException .. caught by BussinessDelegate and do some handling Regards, Prasenjit. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
linefeeds in a resource properties file
Hello,
How to add linefeeds to a property file within struts?
This thread
(http://forum.java.sun.com/thread.jsp?forum=31thread=400653)
says that we can add \n to a String.
However, if I put \n to a resource property line
e.g.
my.key = my value 1 \n my value 2
and then I use html:textarea tag to display the
value
e.g.
c:set var=emailBodyValue
bean:message bundle=ParticipantMsgKey
key=participant.create.step3.defaultEmailBody/
/c:sethtml-el:textarea
property=parameterBuffer.emailBody cols=60
rows=10 value=${emailBodyValue}/
It will display \n instead of line feed.
I notice that html:textarea converts a single
quotation mark ' into #39;
Now, the codes for line feed or new line are #10; and
#13;, but if I put #10; into the properties file, it
will be converted into amp;#10;.
I have tried this by
- having #10; in the properties file
- passing #10; as an argument to bean:message
Both still convert #10; into amp;#10;
I have also tried using empty line with backslash
character in the properties file
e.g.
my.key = my value 1\
\
my value 2
It doesn't work as well.
Any solution to this?

RE: [OT] Exception handling in a J2EE project.
Good question, I'm thinking about the same sort of thing myself. I usually find it easier to give each server side component its own exception, and to throw all exceptions up to the client side with an appropriate message or error code. Obviously, exceptions fatal to the system have to be sent to an administrator - usually through an appropriate log comment or email. If you try to put in too many layers between your exceptions and client view it can be murder, down the line, when bug tracking and extending the application. Perhaps having a common exception class, from which all component exceptions extend, is a nice idea, but I think it invites needless complexity.

I usually find it easier to give each server side component its own exception, and to throw all exceptions up to the client side with an appropriate message or error code. Obviously, exceptions fatal to the system have to be sent to an administrator - usually through an appropriate log comment or email. If you try to put in too many layers between your exceptions and client view it can be murder, down the line, when bug tracking and extending the application. Perhaps having a common exception class, from which all component exceptions extend, is a nice idea, but I think it invites needless complexity.

Hi All, What is the best Hierarcy (framework) for handling exceptions in a J2EE project. I am thinking of some roughly the following Hierarcy consisting broadly of three categories : + MyApplicationException extends Exception ( For handling bussiness exceptions.) - InsufficientBalanceException - InvalidPasswordException - etc. + MySystemException extends RuntimeException (Non bussiness exception, exception due to System problems) + MyEJBException extends EJBException (Not too sure if this is required) My question is : 1. Is this approach correct ? 2. My application flow consists of ActionClass calls BussinessDelegate calls SessionBean calls DAO and ActionClass calls BussinessDelegate calls SessionBean calls EntityBeans How should the exception for take place. Should it be something like this: DAO throws some ApplicationException ... caught by SessionBean thrown as some EJBException .. caught by BussinessDelegate and do some handling Regards, Prasenjit. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Having trouble with html:form tag - Using 1.1
Hi Jim Remove your second servlet mapping in your web.xml. I had the same problem. I've defined two mappings: servlet-mapping servlet-nameaction/servlet-name url-pattern*.do/url-pattern /servlet-mapping servlet-mapping servlet-nameaction/servlet-name url-pattern/home/url-pattern /servlet-mapping As soon as I have removed the second mapping the form action is correct and not the webapp context anymore. Very strange!!! Cheers Oliver *** BITTE BEACHTEN *** Diese Nachricht (wie auch allfällige Anhänge dazu) beinhaltet möglicherweise vertrauliche oder gesetzlich geschützte Daten oder Informationen.

about using DynaActionForm in SQL Maps framework with Struts...
hi, there,
has anybody tried to use SQL Maps framework with struts? i am now using
the struts with SQL Maps framework, all is convenient. i have tried to use
ActionForm instead of create a new javaBean passed to SQL Map parameter.
just like this:
AuthorForm authorForm = (AuthorForm) form;
try {
baseDAO.insertAuthor(authorForm);
} catch(Exception ex) {
ex.printStackTrace();
}
now, i have a query about using DynaActionForm in it...
assume that i am using DynaActionForm and config in struts-config.xml,
What should i do to pass the dynaformBean to SQL Map parameter?
some code like these, but it threw some exception...
DynaActionForm authorForm = (DynaActionForm) form;
try {
baseDAO.insertAuthor(authorForm);
} catch(Exception ex) {
ex.printStackTrace();
}
and in my BaseDAO.java :
public void insertAuthor(DynaActionForm author) throws DaoException {
try {
javaDIYDaoManager.startTransaction();
authorDao.insertAuthor(author);
javaDIYDaoManager.commitTransaction();
}
catch (DaoException e) {
try {
javaDIYDaoManager.rollbackTransaction();
}
catch (Exception e2) { /* ignore */}
throw ( (DaoException) e.fillInStackTrace());
}
}
it threw some exception:
Error executing 'insertAuthor' in 'com/dao/sql/Author.xml'.
Check the Parameter Map (or inline parameters). Check the 'author_name' property.
Cause: com.ibatis.common.beans.BeansException: There is no READABLE property named
'author_name' in class 'org.apache.struts.action.DynaActionForm'
com.ibatis.common.beans.BeansException: There is no READABLE property named
'author_name'
in class 'org.apache.struts.action.DynaActionForm'

Re: about using DynaActionForm in SQL Maps framework with Struts...
Ricky,
You might have a problem using ibatis SQL Maps with Struts DynaForms. I
think that Ibatis is going to try and look for a method called
getAuthor_name() when it would need to use
DynaForm.get(author_name). You might try emailing
[EMAIL PROTECTED] to get a definitive answer.
