R: Struts and PL/SQL
Yes, what you ask is possible, here is a minimal but working example: create or replace function test(obj_name in varchar2) return sys_refcursor is result sys_refcursor; sql_string varchar2(2000); begin sql_string := 'select * from user_objects'; if obj_name is not null then sql_string := sql_string || ' where object_name like ''' || obj_name || '%'''; end if; open result for sql_string; return result; end test; Please note that main reason I use stored procedure is to decouple the physical data structure from the application. In order to keep this separation clean in your scenario I would in some way abstract the dynamic filters (i.e. I would not use column or table names as parameters). Note also that dynamic sql is not as performant as precompiled pl/sql code (but not less performant than a client-built query) and more error-prone, so unless the logic gets *very* complicated I prefer using if/elsif/else/end blocks and have some code duplicated.

We have a form that accepts tons of input values from the web user which eventually get translated into 1 SQL query to pull back the data-set the user is looking for. The problem is that nesting select statements slows done the query, so in some cases, we create a callablestatement, generate the list of IDs on the java side and simply make those part of the query itself inline causing the query to run much faster. There are other form values that would reqiure we either append or not append additional constraints to our SQL. In my procedure, I could easily include all this logic and have a multitude of IF/ELSIF/ENDIF statements which describe the logic but then I have multiple copies of the SQL query to maintain on each IF-structure branch which I would prefer not to do. Is there a way where the string-append approach can be used in Oracle so that after all the conditions have been met, I simply open my cursor once to retreive the data in a PL/SQL procedure?

Re: 2 deep nested forms (solution to 2 dimensional arrays with struts html tags)
No i was wrong works as i thought it would
Need to iterate through the values of the dishes map
public Object[] getDishes() {
return map.values().toArray();
}
%-- var could be anything the index us the important bit --%
c:forEach var=dish items=${course.dishes} varStatus=index
%-- get the correctly indexed key from the getKeys array-%
c:set var=key value=${course.keys[index.count - 1]} /
html:text name=course property=dish(${key}.name indexed=true /
/c:forEach
renders to
input type=text name=course[0].dish(key1).name value=Fish
input type=text name=course[0].dish(key2).name value=More Fish

today and had my chance to combine indexed and mapped properties to
solve the problem.
I want to create a Restaurant Menu editor. So a menu has a few
properties like title and start and end dates for seasonal menus.
So I have 3 action form or nested pojo's
MenuForm
CourseForm
DishBean
I used lazyMap and lazyList to save scoping to session.
MenuForm - has a lazyList or nested courses.
CourseForm - has a lazyMap of dishes and a getKeys() method that
returns map.keySet().toArray()
and dishes are just plain string properties.
public DishBean getDish(String key)
public void setDish(String key,DishBean dish)
The jsp stuff looks something like this.
html:text property=title /
c:forEach var=course items=${menuForm.courses}
html:text name=course property=title indexed=true /
c:forEach var=key items=${course.keys}
html:text name=course property=dish(${key}).name
indexed=true /
/c:forEach
/c:forEach
its not quite as tidy as 2 dimensional array support, but it pretty
clean looking.

RE: [OT] File upload design question
I implement this as follows: On session creation I create a directory in an 'uploads' directory using session id for the name Uploading a file copies the file into the session upload directory and adds the filename (as a String) to a collection on my session scoped form bean. On submission of the form the full paths to the files, in the session upload directory, are passed to my business layer which processes them. On session destruction the session upload directory is removed. Paul -Original Message- From: Jim Collins [mailto:[EMAIL PROTECTED] Sent: 24 June 2004 23:19 To: Struts Users Mailing List Subject: [OT] File upload design question Hi, Appologies for the off topic posting. I am writing an application where a user fills in a form, can attach some files and when they submit the form it kicks off a workflow and saves any attached files to a content management system. This works fine using the struts file upload tools. What I would like to do though is have it work in a similar fasion to Yahoo mail when you send an email with attachments. The user when filling the form out attaches some files, these are then uploaded to the server. When the user then submits the form the workflow is kicked up and the files that were uploaded are moved to the content management system. The files are only copied across if the user submits the form. If the user uploads some files and then decide not to submit the form the files should be deleted.from the server. Does anyone have any ideas on a design for this so that I don't end up with lots of orphan files on the server and when the user submits a form the correct files are copied to the content management system?

As other posters have said, you can't use a jsp tag to provide the value of an attribute in another tag. Ever. However, what you are doing is (probably) redundant. The purpose of the html:hidden tag is to *automatically* create an input type=hidden/ element in your form with the value already set according to the value in your form bean. If you just want to create a hidden input with a value from something other than your form bean just use the html tag directly.

RE: Role based filter with struts
If the web container supports servlet 2.2 only, then options are to
either subclass request processor or creating abstract base
action class to check the roles.
Of course, you can always check the roles in any action's execute method
or in any JSP because you have access to ActionMapping
and HttpServletRequest.
If the web container supports servlet 2.3, I just want to know if there is
any better
option i.e. can we create a servlet filter to check roles? In other words,
can a filter
access ActionMapping and HttpServletRequest of a particular request.

Subject: Re: Security and Struts (JAAS?)
Ralf,
Forgive me if I misintrepreted what you are asking, but I believe what
you are wanting to use the Struts role attribute on actions for
application-managed security.
One way is to put a check on every page as was suggested and is done in
the Struts example.
Another way is to provide a custom RequestProcessor -- this is easier
than it sounds ...
The roles attribute on action is processed via the
RequestProcessor.processRoles() method. You will want to override this
method in a Custom Request Processor -- something like:
code
public class CustomRequestProcessor extends RequestProcessor {
protected boolean processRoles(HttpServletRequest request,
HttpServletResponse response,
ActionMapping mapping)
throws IOException, ServletException {
// Is this action protected by role requirements?
String roles[] = mapping.getRoleNames();
if ((roles == null) || (roles.length 1)) {
return (true);
}
// Check the current user against the list of required roles
HttpSession session = request.getSession();
User user = (User) session.getAttribute(user);
if (user == null) {
return false;
}
for (int i = 0; i roles.length; i++) {
if (user.hasRole(roles[i])) {
return (true);
}
}
response.sendError(HttpServletResponse.SC_BAD_REQUEST,
getInternal().getMessage(notAuthorized,mapping.getPath()));
return (false);
}
}
/code

Hi, i have a portal based on struts.
and i have some public action.
(e.g for listing news and so on)
however.
my problem is the protected area.
i have two roles.
-customer
-supplier
both login via ONE Action
(i got their roles via their usernames...)
okay, i saved something in session
and did if(session...) in an action,
before a user (a logged in) could
do some stuff.
it works okay, but only
if the user enters a URL like
host:8080/trashApp/cust/addStuff.do
(for submitting a form)
i got validation.errors ...
because the execute() of my action is not called...
so i figured out, that i can use ROLES-attribute
for action. nice, but this is jaas, isn't it?
now the (for me) interessting point.
can i add a user (or roles) manually in my
LogonAction.execute() ?
and when, how?
or how to deal generally?
with two user-roles and ONE-LogonAction.class ?
i also watched tomcat-app, that uses struts/jaas for
authorization, but only with ONE role.
so is there anyone out, how has a tip/solution
for me?
thanks alot!

Are you willing to use JSTL? The c:forEach tag has 'varStatus' which
will give you the integer position as you loop through the collection.
This won't be exactly right, I haven't worked with it for a while,
but...
c:forEach items=${myCollection} var=myItem varStatus=myLoopIndex
c:out value=${myLoopIndex}/
c:out value=${myItem}/
/c:forEach
Are these links, or do you need to submit the form with the index as one
of the form properties? Do you have any objection to JavaScript?
With Struts-EL and JSTL, I haven't needed to venture into the Nested
taglib, although I understand there are things it can do that
Struts-EL/JSTL cannot. This may be one of them...
Actually you can do everything with JSTL/EL that the nested tag does,
but I must admit the nested tag makes things cleaner. In the above it
doesn't matter much because you don't have Lists nested within each other.
Imagine a case, though, where you had a Company object that a Collection
of divisions and then each division had a collection of departments and
you want to display a form that lest you edit the departments in each
division. You'll see the benefit of nested below (sorry for the ugly
wrapping you'll get. If you want I can send the example to you offlist).

image submit and lookupDispatchAction - drives me struts
hi there!
i wanted to use images to hide my ugly submit button names, but exchanging
html:submit with html:image doesn't work;
this is what is rendered:
html:submit property=action
fmt:message key=profiles_action_${ownerName}_${prepopulatedActionPart}/
/html:submitbr/
html:image src=images/edit-button.jpg property=action
fmt:message key=profiles_action_${ownerName}_${prepopulatedActionPart}/
/html:imagebr/
bean:define id=editButton type=java.lang.Stringfmt:message
key=profiles_action_${ownerName}_${prepopulatedActionPart}//bean:define
html:submit property=action value=${editButton}/br/
html:image src=images/edit-button.jpg property=action value=${editButton}/
gets rendered to
input type=submit name=action value=EDIT_USER /br/
input type=image name=action src=images/edit-button.jpg /
input type=submit name=action value=EDIT_USER /br/
input type=image name=action src=images/edit-button.jpg value=EDIT_USER /
so the html:submit buttons do work, but neither of the html:image buttons
pass the parameter on and i get a null reference for
request.getParameter(parameter);
(with parameter.equals(action))
the resulting error message is:
Request[/action/lookupDispatch] does not contain handler parameter named action
anybody knows what could help?
thanks,

custom error message handling

I still want the list of errors produced by html:errors/ at the top but I would like to place something like ** next to any field that had errors.

Problem With Struts-config. Pls Reply ASAP
Dear Friends,
I'm a bit out of touch with coding. My need is to display some
orderdetails after a successful Login. So I have a Login View and a
SucessView. So the orderDetails are picked up as a vector from the
DAO and throu Delegate returned to the SuccessView. I display the
OrderDetails using Logic-iterate. I'm also using Tiles. This works
fine if I have an intermediate JSP in the Login View which has a
Button Action which inturn calls the DisplayOrders Action.
so my intermediate JSP Looks Like this :
html:form action=/displayOrders
table width=98% height=78% border=0 cellspacing=0
cellpadding=0
tr
td width=9%nbsp;/td
td width=91% Valign=top class=lg_title!--
#BeginEditable Body1 --font color=#CC face=Arial,
Helvetica, sans-serifbfont color=#00br
Display Orders/font/b/fontfont color=#CC
face=Arial, Helvetica, sans-serifbbr
br
/b/font
br
br
br
br
font color=black
input type=submit align=center class=frmBtnS value=Search
name=action onclick=doSetUserAction('%
=SucessView.ACTION_DISPLAY_ORDER_LIST %')/font font color=black
..
And My Struts-config looks Like this:
action path=/Login
type=com.equifax.emortgage.abstractui.GenericStrutsAction
name=com.equifax.emortgage.ui.LoginView
input=/jsp/Login.jsp
scope=request
validate=true
forward name=com.equifax.emortgage.ui.LoginView
path=LoginViewResult/
/action
action path=/displayOrders
type=com.equifax.emortgage.abstractui.GenericStrutsAction
name=com.equifax.emortgage.ui.SucessView
scope=request
validate=true
forward name=com.equifax.emortgage.ui.SucessView
path=displayOrders/
/action
And my Forward Definition.xml looks Like this:
definition name=LoginViewResult path=/jsp/MasterLayout.jsp
put name=header value=/jsp/Eheader.jsp/
put name=body value=/jsp/appHome.jsp/
put name=footer value=/jsp/Efooter.jsp/
/definition
definition name=displayOrders
path=/jsp/MasterLayout.jsp
put name=header value=/jsp/Eheader.jsp/
put name=body value=/jsp/success.jsp/
put name=footer value=/jsp/Efooter.jsp/
/definition
Now Instead of calling appHome.JSP which inturn calls success.jsp how
can I call success.jsp directly. ?
Pls tell me the changes to be made in struts-config.xml. and forward-
definition.xml.
thanks in advance,
regards,
kiran

Hi, You are talking about dynamic SQL in stored procedures. But there is a nice option that provides you dynamic SQL alike features: iBATIS SQL MAPS. When you declare your statements inside map config file, you can use a set of tags to build your statement according to parameters you pass to your statement. It works nicely for me.

In order to keep this separation clean in your scenario I would in some way abstract the dynamic filters (i.e. I would not use column or table names as parameters). Note also that dynamic sql is not as performant as precompiled pl/sql code (but not less performant than a client-built query) and more error-prone, so unless the logic gets *very* complicated I prefer using if/elsif/else/end blocks and have some code duplicated.

Trying to learn Struts, need help understanding design process
I've been a C#/.Net developer for two years. Recently my company has decided to move towards Java/Struts, so i've spent the last three weeks familiarizing myself with Java, JDBC, Type 4 drivers, Tomcat, Ant, and Struts. Struts is the last thing i've tried to tackle, and I thought I had a handle on it, however I don't. I'm not sure of the best (or correct/standard) way of doing simple things. I've read that if I ever have a *.jsp showing in the address bar outside of the entry page, i've done something wrong. I'd like to give an example, and hear suggestions on the correct way to implement such an idea. Simple example to follow... Let's say I have a database that contains a two tables: one called teams, and one called riders. There is a one-to-many relationship between teams and riders based on a teamid. In the teams table, we have the following data (Primary Key in parens): (1) USPS (2) T-Mobile (3) Cofidis (4) Phonak ... In the riders table, we have this data (relationship in parens): Lance Armstrong (teamid = 1) George Hincapie (teamid = 1) Jan Ullrich (teamid = 2) Alexandre Vinokourov (teamid = 2) David Millar (teamid = 3) Tyler Hamilton (teamid = 4) ... From the Index.jsp, there should be a link to another page that will have a single select box, and a submit button. The select box needs to be populated with a list of teams/teamids from the database. Upon submission of the form, all riders will be displayed in a table. Pretty simple stuff, except I can't seem to figure out how to do it with Struts. The closest i've gotten is to have a static Teams.jsp with an input-text box, which calls an Action to display the users. In otherwords my Index.jsp links to Teams.jsp, instead of something like Teams.do (and I can't figure out how to populate a select box from a Vector or other sort of list).

I am writing an application where a user fills in a form, can attach some files and when they submit the form it kicks off a workflow and saves any attached files to a content management system.

The user when filling the form out attaches some files, these are then uploaded to the server. When the user then submits the form the workflow is kicked up and the files that were uploaded are moved to the content management system. The files are only copied across if the user submits the form. If the user uploads some files and then decide not to submit the form the files should be deleted.from the server. Does anyone have any ideas on a design for this so that I don't end up with lots of orphan files on the server and when the user submits a form the correct files are copied to the content management system?

RE: Trying to learn Struts, need help understanding design proces s
A nice combination of tools/libraries we use is the display tag library to display tabular data in a jsp page and iBATIS SQL Maps for data access. Both are widely used as far as I know. The iBATIS site also has a JPetStore demo based on Struts which provides a great example (source code included) of how to implement a struts application, based on best practices. http://displaytag.sourceforge.net/ http://www.ibatis.com Hope this helps.

RE: Trying to learn Struts, need help understanding design process
A general design for this sort of thing would be to load your collection of teams at application start up and put them into the ServletContext. Define an action for displaying the teams page and an action for processing the user input after they have selected a team. Define your actions to forward to these pages and not redirect. The display action can simply be a forward defined in your struts-config.xml since the teams already exist in the ServletContext. You will have to subclass one the many Action classes in order to process the user input subsequent to their team selection. The teams page can enlist the help of the html:optionsCollection .../ to render the drop down list. http://jakarta.apache.org/struts/userGuide/struts-html.html#optionsCollection As Brian already mentioned, you can utilize some third party tools like the displayTag library found here http://displaytag.sourceforge.net/ to render the riders in tabular format. Hide your pages behind WEB-INF. Something like WEB-INF/pages/teams.jsp. Note that most (but not all) web containers disallow direct access to resources which are in the WEB-INF directory. This helps enforce the MVC aspect of your web application. There are several ways to tackle this problem and the above is just some high level advice. I would review (actually install and do a code trace) the Struts example web apps. hth, robert -Original Message- From: Jamison Roberts [mailto:[EMAIL PROTECTED] Sent: Friday, June 25, 2004 2:46 PM To: Struts Mailing List Subject: Trying to learn Struts, need help understanding design process I've been a C#/.Net developer for two years.

RE: Trying to learn Struts, need help understanding design process
It almost seems like you're coming at this from the wrong end, with the page calling the action. It's the other way around. I know that with php and asp development is page centric. In JSP it's action centric. The page is just a display. Something like this is what you want I think: /context/showTeamSelection.do -- populate your lists, collections in request scope would do it. and forward to the JSP. This can also be the ForwardAction if you have nothing to setup for the page. Then later, if you do have something change the struts-config.xml to point at the new action, nothing else changes. Person clicks submit, which goes to /context/teamSelected.do -- which pulls from the database, populates the request scope with appropriate data and then forwards to the page. -Original Message- From: Jamison Roberts [mailto:[EMAIL PROTECTED] Sent: Friday, June 25, 2004 11:46 AM To: Struts Mailing List Subject: Trying to learn Struts, need help understanding design process I've been a C#/.Net developer for two years.

Is it possible to reuse the same FormBean with different actions?
I have a few jsp pages that use almost the same information. I am using a formbean for one of them right now for validation. Of course I'd like to re-use the this same bean with the other jsp pages too since the info is so similar. But here's the catch, theres only one input field in an action mapping, meaning it will always send the user back to the same jsp page if validation fails, rather than different ones. Is there some other element in the action mapping I can set to get around this? I can always have 2 or 3 formbeans and copy properties from one to the other, but that doesnt seem like a very good solution to me. Does anyone have any ideas? -Asif

Sounds like you should be setting the FormBean to be in session scope for the Actions -- as far as the input attribute being a problem -- I really don't understand.

Thanks for the code snippet Rick. It helped trim down a lot of code.

if I set the action scope=request I get:
javax.servlet.ServletException: BeanUtils.populate

Caused by: java.lang.IndexOutOfBoundsException: Index: 2, Size: 0
or
Caused by: java.lang.NullPointerException
make sure you don't have scope=request in your action ...
/action
/VERY-IMPORTANT
Do you _have_ to put forms that use nested beans in session scope?
Using your example, my getters/setters would look something like:
public void setDivisions(Divisions[] divisions) {
this.divisions = divisions;
}
public Divisionsa[] getDivisions() {
return this.divisions;
}
On my action, having scope=request would cause problems. Changing
that to scope=session solved the problem.
Do you know of a way I can avoid storing the ActionForm in the session?
I've caught a few references to Common's LazyList (page was formatted
correctly in Google cache under Mozilla 1.7 but not when the original
url was clicked on):
http://tinyurl.com/yqot7
Should I declare this.divisions to be some sort of List or LazyList
instead of Divisions[]?
Is any of this making sense?

Re: Trying to learn Struts, need help understanding design process
Struts works in layers. You might want to create 2 DAO objects to unit test. 1 to return a list of teams. The other DAO takes an argument of the team ID and returns a list of memners of the team. (Many DAO's out there, try iBatis.com). Once you have that unit tested, you can write an action that populates object from DAO 1, and puts it in request scope; so you can display the JSP. From that JSP, call another action, where you get the parm out of the request of the team you want returned. Good luck. On Struts wiki, there are 20 books on Struts, and many online tutorials on Struts (look at one from Rick Reuman) .V Jamison Roberts wrote: I've been a C#/.Net developer for two years.

From: Pietro Dansk [mailto:[EMAIL PROTECTED] I want this form to simply return to the page or action that it was previously at. What is the most elegant way to do this? In Struts, everything goes forward so the go back where you came from problem comes up repeatedly. The 'coming from' page needs to put something in the request so you can figure out where to go back to. Then instead of looking up a forward from struts-config.xml, you can construct a new one and return that.

if anybody could kindly show me the JSTL equivalents?

Is there anyway an Action can dynamically return to a page based on input?
I have a form which appears on multiple pages. The form leads to an action which changes a simple property. After doing this, I want the action to simply lead back to the individual page from which it came. I can't register a single input within the action tag of the struts-config.xml file (because there are multiple actions from which it could possibly come). Therefore, it doesn't seem like I can use the mapping.findInputForward() method. I want this form to simply return to the page or action that it was previously at. What is the most elegant way to do this? --Pietro - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Whoever told you that should be shot! It's not that JSTL is deficient,
its just sort of like saying I have heard that a honeydew melon can be
used instead of a canteloupe. Theyr'e both round fruits, but they taste
different.
JSTL relies on scoped variable where the scopes are pageScope,
requestScope, sessionScope, and applicationScope. To get the variables
into these scopes should be the job of your actions. You can create
these scoped variables using other things such as jsp:useBean and
bean:define. However, the best place is your action, (or other things
like PlugIn, SessionListener, etc.).
I have not tested all of these so YMMV.
I still have some problem with initializing
variables and if statments; for example, I do not know
how to write in JSTL of the following:
1. int i = 0;
c:set var=i0/c:set
2. i++;
c:set var=i value=${i + 1}/
3. String prevArticle = null;
c:set var=prevArticle value=/
4. if ( numberOfPosts - 1 == 1 ) {}
c:if test=${(numberOfPosts - 1) eq 1}
/c:if
5. if ( nextTopic != 0 )
c:if test=${(nextTopic ne 0}
/c:if
6. String threadID = String.valueOf( threadID_int );
c:set var=threadId value=${threadID_int}/
7. if ( threadRows.size() == 0 ) {}
c:if test=${empty threadRows}
/c:if
8. if ( previousOffset = 0 || nextOffset = 0 ) {}
c:if test=${previousOffset ge 0 and nextOffset ge 0}
/c:if
9. if ( prevArticle != null ) ( !article.equals(
prevArticle ) ) {}
c:if test=${(not empty prevArticle) and (article ne prevArticle)}
/c:if
Good Luck!
