Re: UPON APPLICATION STARTUP!!!!!!!!!!!!!!!!
Thanks Nathan, Andrew. I am sorry that my earliler post was not specific and a little bit on the sassy side. Yes. My forms are session mapped forms and I will be getting the default values from my database. Andrew, the reason why I decided not use an action to load the default values in the forms is that this would be a query to the database *everytime*. Since, theses default values are static (will never change), I thought it makes more sense to load then upon application startup and have it within the current session. Oops, they should span accross multiple sessions, therefore, as you and Nathan suggested they should be put within the servlet context. Andrew, can you elaborate a littile bit more on the ActionForm reset issue that you mentioned? Thanks. _CJ On Sunday 10 August 2003 11:08 pm, Andrew Hill wrote: Yeh alright mate. Keep ya hair on and enough with the shouting already! Since the forms are only instantiated when a request for that mapping comes in its gonna be kinda hard to prepopulate values on them cos they dont exist yet. Indeed unless you are using session mapped forms (such as for a multipage wizard or such like) the form is only going to exist for the scope of the request. Now Im assuming that you need to read these default values from somewhere (which must be why you dont just slap em into the form constructors directly). Since they dont change while the app is running (another assumption your post didnt bother clarifying) your best bet would be to read them into some kind of config objects (perhaps even a 'prototype' instance of the forms in question) and store these in the servlet context. Implement a struts plugin to do this at startup time. You could initialise the values in the form instance from these config objects in the reset method. Dont forget to do this only on the first reset (or you will overwite input). I reckon you would be best off doing as you were advised and copying the defaults into the form in an action though rather than overloading the reset method for this purpose. As for the lists of selectable choices in things such as drop downs - that would best be left as shared beans in servlet scope (like Nathan says in his reply to your post) - you would only want to copy values into the form instance for defaults for stuff, as you can have your tags access the shared beans directly for such tasks as rendering options in selects... -Original Message- From: Curtney Jacobs [mailto:[EMAIL PROTECTED] Sent: Monday, 11 August 2003 13:46 To: Struts Users Mailing List Subject: UPON APPLICATION STARTUP Greetings!

Calling a default Action upon App startup
Greetings everyone! I would like to preopulate serveral forms with default values retrieve from a database upon application startup or after a successful login by the user. I have an approach in mind, however, I am not sure if it is the most efficient or best approach. My approach is to use a filter that creates and stores in memory default ActionForms. The ActionForm will contain default values for select fields (or any other fields) retrieved from a database. The ActionForms will be stored within the current user session and then controll will be given over to Struts ActionServlet. Another similar approach would be to register a listerner (HttpSessionAttributeListener) that would essentially wait for a specific attribute to be added into the session (i.e SETUP_FORMS) then it would query the database for neccessary application setup data. I read the message archive, and a few have suggested calling a setup action per request that prepopulates the default values in the ActionForm. This is a valid approach, but IMHO only for small applications. It just seems that there will be to much traffic going on between the app and the database. Correct me if I am wrong.

Re: Calling A default Action Upon Application Startup
Greetings Carlos. Thanks for replying. Yes. I can populate a form that way. However, it wouldn't quite give me what I want. For instance, as the application is initially loaded there should be default values already in the forms; this should be done prior to any user action. I like your one action approach. Is there a way to call this action as the application is initially loaded. Again, no user interaction should trigger this action class.

Re: Calling a default Action upon App startup
Greetings Mohan. Thanks for replying. The reasons why I mentioned the listener approach because I am also loading the user profile upon successful login. You are correct in that the mixing of servlet listeners and Struts forms is not a good idea. Your ServletContextListener approach seems interesting though. The data I am using to populate the forms are merely reference/lookup data that the user can select from. Thus the data is very static, does not change at all. Are you currently using the ServletContextListener for such data? Another approach would be to override the ActionForm reset method to load the default values in the form. However that violates separation of concerns. the ActionForm should not be doing any kind of database lookup. _CJ On Tuesday 05 August 2003 12:11 am, Mohan Radhakrishnan wrote: This is what I think about the listener approach. In our project even though we use HttpSessionAttributeListener, we are loading only the login user profile as a java bean. We don't mix servlet listeners and Struts forms. We could load data into POJO's and then copy it into ActionForms whenever they are needed. I am not sure about the efficiency of this approach for large number of forms. The filter is hit even before the ActionServlet is hit the VERY first time. So Struts is not even loaded unless you use the load on startup tag. Again here we load our own javabeans. But when we need to prepopulate we set up our ActionForms Just-in-Time. Our data that don't change often is in javabeans loaded by our ServletContextListener.

No. The same form displays and update the data. When the user clicks on his/her name the form is populated with his/her profile information. The information can then be edited by the user.

Re: Reflecting Changes in a Form After data has been updated
Sovle it. Thanks for the replies Mike, it got my brain thinking. The problem and solution is listed below, just in case anyone else is having a similar problem. The problem was I was storing the prepopulated ActionForm in the session scope while the new updated ActionForm was stored in the current request scope. Thus, after the update request was completed that instance of the ActionForm was lost and the ActionForm stored in the session (old data) was just redisplayed. Therefore, all I had to do was change my update action within my action mapping from request to session. _CJ My problem was I was storing On Tuesday 29 July 2003 10:12 am, Mainguy, Mike wrote: That seems odd. Are you sure you aren't somehow loading the old data somewhere before you actually do the update operation. Perhaps you are inadvertently doing a POST-LoadFromDB-SaveToDB-Respond.

Regardless of whether or not you store SQL in a properties file, the idea
is that you have one map with criteria_name=user_value and another map
with criteria_name=SQL_chunk. That way, you can easily insert the value
the user typed in into the matching SQL chunk that performs the query.
You construct the full query string from the various chunks.

on the form. I used this technique recently (without Struts so I had to
do the Map backed form business by hand); it's really not very much code
and is easy to add criteria to.

Hi everyone,
I know this is of the topic but I am hoping that someone has came

and wouldn't mine shareing with me how they eloquently solve this
problem.
I have an ActionForm (and corresponding Action class) that takes input
from
the user and does a search depending on the inputed criteria. With three
or
four criteria it is not a problem to dynamically build the query,
however my
input form will be growing to about 10-15 criteria.
Also, the search criteria may span serveral tables. If you have an
elegant
solution to this problem/task please share.
Currently, I have the following. Not very elegant.
StringBuffer queryStr = new StringBuffer();
queryStr.append(select * from + TableNames.STUDENT_TABLE + where
1=1);
/* append additional conditions to where clause depending on the values
specified in studentVO */
if (studentVO.getStudentID() 0) {
queryStr.append ( and student_id = ' +
studentVO.getStudentID() +
');
}
if (studentVO.getLastName() != null
(studentVO.getLastName().length())
0 ) {
queryStr.append( and lastname = ' + studentVO.getLastName() +
');
}
if (studentVO.getFirstName() != null
(studentVO.getFirstName().length() ) 0) {
queryStr.append( and firstname = ' + studentVO.getFirstName()

}
queryStr.append(;);

Re: Making a Form non-editable
To everyone, would it better to just have a seperate view to display read only data. In other words, do not use the form to display the queried data. But, simply use a JSP page to display the data (naturally, with proper formatting). The above seems a tad bit cumbersome or redundant; having two seperate views for the display of the same data, however for different purposes.

Hello Mark. Just so I don't misuderstand, are you saying that for each input tag there is a corresponding hidden tag.

Security Filter and ActionForm
Greetings!! I have a login ActionForm (LogInForm) and a associated login Action class (LogInAction). When the form is submitted, the request is intercepted by a Security Filter. The Security filter authenticates and perform necessary authorization checks on the user via a ldap server. If the user authentication fails, let say because of an invalid password, how can I use my ActionForm (LogInForm) to indicate this error to the user? I am aware that the Struts ActionForm and Action have not even been instantiated/intitialize, since the security filter intercepted the request. I have thought of setting an attribute in the request scope, for example, an invalid flag that the ActionForm validate method can check for. This will then trigger the display of the login form and asociated error message to the user. I am not sure if the above is good practice :( Any suggestions or comments will be much appreciated.

Since (as far as I know) the html:form Tag is bound to exact one HTML form, I don't think that this is possible. You could possibly inherit one overall form from all the simple forms but you will run into problems with validation (hence only one validate method for the form) and the form name (the form extending all the other forms will be saved under a single overall name) and even properbly form bean property names if they interfere, so this does not seam a good approach to me.

(Sorry Cedric, I should have posted the error message earlier) All help is greatly appreciated. _CJ - Root Cause - java.lang.NullPointerException at org.apache.jsp.tabsLayout_jsp._jspService(tabsLayout_jsp.java:121) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:136) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:204) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:289) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:240) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:684) at org.apache.catalina.core.ApplicationDispatcher.doInclude(ApplicationDispatcher.java:575) at org.apache.catalina.core.ApplicationDispatcher.include(ApplicationDispatcher.java:498) at org.apache.jasper.runtime.JspRuntimeLibrary.include(JspRuntimeLibrary.java:820) at org.apache.jasper.runtime.PageContextImpl.include(PageContextImpl.java:395) at org.apache.struts.taglib.tiles.InsertTag$InsertHandler.doEndTag(InsertTag.java:865) at org.apache.struts.taglib.tiles.InsertTag.doEndTag(InsertTag.java:487) at org.apache.jsp.classicLayout_jsp._jspx_meth_tiles_insert_2(classicLayout_jsp.java:160) at org.apache.jsp.classicLayout_jsp._jspService(classicLayout_jsp.java:81) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:136) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:204) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:289) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:240) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:684) at org.apache.catalina.core.ApplicationDispatcher.doInclude(ApplicationDispatcher.java:575) at org.apache.catalina.core.ApplicationDispatcher.include(ApplicationDispatcher.java:498) at org.apache.jasper.runtime.JspRuntimeLibrary.include(JspRuntimeLibrary.java:820) at org.apache.jasper.runtime.PageContextImpl.include(PageContextImpl.java:395) at org.apache.struts.taglib.tiles.InsertTag$InsertHandler.doEndTag(InsertTag.java:865) at org.apache.struts.taglib.tiles.InsertTag.doEndTag(InsertTag.java:487) at org.apache.jsp.tabs_jsp._jspx_meth_tiles_insert_0(tabs_jsp.java:76) at org.apache.jsp.tabs_jsp._jspService(tabs_jsp.java:53) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:136) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:204) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:289) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:240) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:247) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:193) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:260) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(StandardPipeline.java:643) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:480) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:995) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(StandardPipeline.java:643) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:471) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(StandardPipeline.java:641) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:480) at
Re: tabsLayout.jsp ServletException??
Hi, I am using Resin EJB server. I begining to think that the problems I am having could be due to the container. I will download tomcat and run your tiles examples on it. If that works, then I have to look closely at my resin configurations.
