About Tiles

[Koon Yue Lam]

Hi, I want to build a webpage using tiles, the structure is:

Header
Body
Footer

super classic layout but I have one question, if the content in Header
and Footer are read only and will be nearly the same throughout entire
user session. How can I just reload the body part? and keep the Header
and Footer static?
(the content of Body is generated according to the content of Header)

however, each user will have a page to modify their info (name,
age...), and after these changes have made to DB. Both Header and
Footer must force to reload

so how can I trigger reload of Tiles as I wish, but keep those tiles
static for the rest of time??

Best regards

RE: Multiple Tiles Definitions Factories in a servlet context?

[Alef Arendsen]

Guys,
 
just wanted to pop this one up again. A user on our list has problems applying 
multiple tiles definition factories. Is there any way this is possible??
 
Thanx,

Subject: Multiple Tiles Definitions Factories in a servlet context?



Hi guys,

A user on our list (Spring) has configured two servlets both including a
Tiles Definitions Factory using Spring's integration code. The
TilesUtilsImpl however specifies a static identifier (which we're using
to bind the factory in the servlet context) for the factory, causing the
first Definitions Factory to be overwritten by the second one.

Any idea how to solve this?

Thanx,

Re: Tiles breaks my page that uses logic:iterate

[Janne Mattila]

With Tiles:









without tiles (works fine):









So, three actions. "Init" is called only the first time to give default 
values, after that it is Save => Get => Save => Get and so on as long as 
user keeps submitting the form. Purpose of "Get" (and also "Init") is to 
read the collection of possible choices (allChoices) from database.

OK so post the bits of your struts-config which show the forms and action
mappings for
1) The action which renders the page
2) The action the form will post to (i.e. "/TilesSaveInputs")

Hi All,
I have a typical problem. Recently I developed a new page with struts
1.1. All the labels of the page come from the properties file. I access
these labels with bean:message tag. 

Example :  

This works fine in my local server where struts 1.1 is there. When I
moved this to remote server which has struts 1.0 it gives me error like
following.
javax.servlet.jsp.JspException: Missing message for key

Both these server has Apache webserver and OC4j container.

The key is there in properties file and it is in path as defined in
Web.xml. Most strange is other pages those were developed before are
getting the other keys properly. But all these new keys are not
accessible. Is there a size or number of key limitation  for properties
file?  None of the new pages getting the keys. Apache/OC4j Restated so
many times and I am trying to figure this from last two days without

Please help.

Re: Connection and Tomcat server

[Jignesh Patel]

I can say, this is purely a connection closing problem.

That's the reason when you restart the tomcat it works fine till the
time all the connection in the connection pool utilize and then after it
hangs.

Are u closing your connection in finally block?

Re: html:text - want to set disable= to a bean value

[Stuart Guthrie]

Thanks Rick.

I need to rely on the backend to decide whether to enable/disable as the
requirement is a 'business rule' not an interface decision. Here are the
factors:

- What 'stage' is this row of the table reached determines if this field
can be changed or not.
- What 'security level' the current session's user has determines
enable/disable.

So unfortunately, putting all this in the view would lead to huge
amounts of choosings. I'd rather the view was really dumb and just
reacted to decisions @ the backend.


> Then you can do:
>  disable="${userFormBean.customerCodeEnabled}"  />

This looks promising. Thanks for your help..

multiselect with a map-backed form property

[Adam Murray]

I have a form with a dynamically generated list of constraints that can
be turned on or off, and each constraint has a set of values associated
with it. My form has two relevant fields:

private String[] selectedConstraints;
private Map values;

public String[] getSelectedConstraints() {
return selectedConstraints;
}
public void setSelectedConstraints(String[] selectedConstraints) {
this.selectedConstraints = selectedConstraints;
}

public Object getValues(String key) {
return values.get(key);
}
public void setValues(String key, Object value) {
values.put(key, value);
}


To keep track of which values are associated with which constraint, I
use the string from the selectedConstraints array as the key into the
values map. My jsp page looks like this:



  


  



  

 
   
 
...


The above works perfectly fine as long as only want to select a single
item from the select drop-down box. The problem is some of the
constraints can have multiple values, so I changed the select to a
multi-select:

 

But then the form is only ever populated with the *first* string
selected from the multiselect box. Since a map can hold a String[] as
easily as a String, I'm a little confused by this behavior. I tried the
following things with no luck (these changes are in the struts action
that forwards to the jsp above):

1) inserting an empty String array into the values map for each key in
an attempt to coerce the user of String arrays

2) inserting a wrapper class into the map for each key:
public class SelectedValues {
private String[] selectedValues;
public String[] getSelectedValues() {   
return selectedValues;
}
public void setSelectedValues(String[] selectedValues) {
this.selectedValues = selectedValues;
}
}

and I updated my jsp to:
 

but that causes the following exception:
javax.servlet.ServletException: BeanUtils.populate
org.apache.struts.util.RequestUtils.populate(RequestUtils.java:1254)
...
root cause:
java.lang.IllegalArgumentException: No bean specified

org.apache.commons.beanutils.PropertyUtils.getPropertyDescriptor(PropertyUtils.java:837)
...


I can get the multiselect to work if I create a String array for each
constraint, but that defeats the purpose since this is supposed to be
dynamically generated. I'm out of ideas for other things to try with the
map-backed approach. Can someone tell me what I'm doing wrong here?

Thanks,
Adam

The short version is that it is handled automagically for you.  No need to borrow or 
return the connection etc.

RE: connection pooling

[Saurabh Bhatla]

Jim,
  I understand most part of it now. the only thing that i dont
understand is how will the connection pooling be handled. I am using
tomcat 5. will the following code(from the link that u sent me) serve
the purpose?

Re: Overwritting RequestProcessor, how to???

[David Durham]

Rick Reumann wrote:
This is another reason why I still think calling validate() manually 
from your Action is a much better approach then relying on Struts do it 
for you. If you call form.validate() from your Action you then have 
control over what you want to do. So in your Action you could do...

//in your Action execute or dispatch method:
ActionErrors errors = myForm.validate();
if ( errors != null ) {
   mySpecificMethod();
   return( mapping.findFoward("SUCCESS");
} else {
   saveErrors(request, errors);
   return( mapping.findFoward("SUCCESS");
}
 

On this note, but slightly different, I use something very similar to 
this within all DispatchActions.  My reasoning is that you can only 
configure one input attribute for an Action.  DispatchActions obviously 
open up the possibility for several inputs.  This is something that the 
current configuration doesn't handle very well, IMO.

In particular, I think it would be interesting to see a configuration 
for DispatchActions like so:



 
  

 
  


Obviously you can achieve very similar results by simply creating 
multiple Actions, but perhaps a configuration like this would allow for 
some inheritence (as in, define attributes for the DispatchedAction and 
optionally override them for nested actions, share/override mappings 
within the Dispatch's scope).

Thoughts?  Has this already been mentioned?

RE: connection pooling

[sridhar ramalingam]

Saurabh,
If you want to do some kind of initialization when your server starts
up, you can implement the org.apache.struts.action.PlugIn interface and
override the init() method to do your initialization. Check Logon
example application,
org.apache.struts.webapp.example.memory.MemoryDatabasePlugIn.java for
more details.

Sridhar

Yes, that is correct.  I acutally implment that in my DaoFactory class, and put the 
resultant connection from the data source in the DaoFactory class.  That allows me to 
easily de-couple the dao class for testing.

Depends on the web server... websphere has it's own, tomcat allows you to have several 
choices, and I have no idea what BEA does.

RE: connection pooling

Jim,
   I am sorry but I am confused now. Just correct me if I am
wrong I want to call my DAO from my Action class. So the snippet
that you sent me would go in my DAO class in the function
getConnection() (or something like that). 
 And if what I said is correct then does it mean that I dont need to
have a connection pool class and my webserver would handle everything
for me.

Ah, okay.. I also posted a link to the struts way to do the JNDI data source stuff 
in that case.. you follow your web app servers guide on how to setup a data source, 
then you follow the destructions for a normal jndi data source. Something like:

/**
 * 
 */
public static DataSource getDataSource() throws NamingException {
if (ds == null) {
Context ctx = (Context) new InitialContext();
ds =
(DataSource) ctx.lookup(
"jdbc/yourDataSource);
}
return ds;

I was about to say something like this, but I don't think it works.

validate() *returns* an instance of ActionErrors. So how does the base
class' validate() method know the subclass' validate() method found any
errors? Yeah, you can call super.validate(), but how do you check for that
condition inside of the base class? There's no .saveErrors() method inside
of the ActionForm classes

This is another reason why I still think calling validate() manually 
from your Action is a much better approach then relying on Struts do it 
for you. If you call form.validate() from your Action you then have 
control over what you want to do. So in your Action you could do...

//in your Action execute or dispatch method:
ActionErrors errors = myForm.validate();
if ( errors != null ) {
   mySpecificMethod();
   return( mapping.findFoward("SUCCESS");
} else {
   saveErrors(request, errors);
   return( mapping.findFoward("SUCCESS");
}
Another option is that you can still have your forms over-ride a base 
ActionForm and then at the end of the validate method, if you get 
errors, you can then call super.validate() which will call your 
mySpecificMethod(); of your Super class.

And doing that with struts:

connection pooling

[Saurabh Bhatla]

Hi all, 
   I have just started working with struts a few days ago, and I
understand most of it. The only thing that i dont understand is, if i
make a connection pool then where will it be initialized. In servlets I
know that it can be done in the init() method but in struts framework
there is nothing like an init() method. I have the connection pool class
that i have written and i was using in one of my servlets. Now i want to
know how to initialize the connection pool object and how to pass that
object to all Action classes.

Any suggestion would be greatly appreciated.

regards
saurabh

I agree overload validate(), call super and if you get any errors back, then do 
your custom stuff.  Provided that your custom stuff your running after validation 
doesn't break the one method, one function rule.  If that's what you want, then I'd 
look to see if there's another way of triggering whatever it is you want... say with a 
tag or something.

RE: Overwritting RequestProcessor, how to???

[Frank Zammetti]

Maybe it would be enough to just write your own base class that extends 
ActionForm, have your "common" code in it, and then extend your ActionForms 
from that class?

If not, take a look at my code from http://www.omnytex.com/strutsws for an 
example of writing your own command processor.  I get the feeling it's not 
the right approach, but I could be wrong.

Hi,
i'd like to overwirte RequestProcessor, but actually i
don't really know if it's a good idea.
Here's the point:
I'd like to have one more action if my form.validate()
method fails on ActionForm. I'd like to do some
specific stuff everytime the validate method fails.
Then, i thought of overwritting the RequestProcessor.
Is that a good idea, or there's another way to
accomplish what i want???

Re: How to call multiple submits in a jsp form(in STRUTS other than using javascript)

[Frank Zammetti]

Alternatively, don't forget that Actions are just classes, and as such you 
can always instantiate an instance of an Action from within another and call 
it's execute() method yourself.  Your app has to be designed to allow for 
this, but it's fairly trivial to do so.  LookupDispatchAction is I think the 
better way though, but sometimes the simpler approach is sufficient.

Ravi, without getting real complicated, I use PlugIns to do this!

Implement org.apache.struts.action.PlugIn. You only need to write two

methods -- init and destroy. In your init method, gather some data store

it as application scope attributes (you get a reference to the

controller Servlet in the init method). Finally, register your PlugIn

with struts-config.xml. When your Struts app initializes, your PlugIn's

init method is invoked. Your JSPs now have easy access to the cached

data, as do your Actions.

Re: Read only iterate?

[dhay]

Mike,

The indexed tags do make the code much cleaner.  And they are definitely
not read-only (as you've discovered, you don't need them if you want things
read only!!).

There are lots of posts in the archives about it, and I posted working code
here:
http://www.mail-archive.com/[EMAIL PROTECTED]/msg12084.html

cheers,

David

Yes, that works.  Thank you.  However, I would put that in the general
category of a workaround rather than the correct solution.  I read the
reference you mentioned before making my original attempt.

In that reference, the authors themselves feel there is a better solution:

  " The JSP expression syntax for the property attribute is somewhat
messy and easy to get wrong so it's something we want to avoid.
One way to make this a little cleaner is to use "indexed tags"'

and then go on to talk about "indexed tags" as being superior.  I took from
that the notion that I should avoid the first solution; that indexed tags
would do the same thing.

If that's actually true then I'd be delighted to see how to make it work.
Nowhere in the discussion do the authors drop the bomb that using indexed
tags makes the whole situation read-only and I still think that there must
be
some way to make it work using indexed tags -- I just haven't yet found it.

However, thanks for pointing me at the earlier solution -- it does work,
awkward as it is, and that's really important when one has a product to
deliver.

Hi,
MS IE has default setting:
 Tools->Options->Advanced->Browsing->"Show friendly
HTTP error message"
When it is checked, the IE default error page is used
not your own 404 error page.
How can I change the http status code in Struts
application so that my own 404 page is used ?
thanks

Hi all,
Thanks for the info.  Here's another issue.
What if I have an employee search screen that wants to show only some of 
the information of an employee (not all).  What do you do then?
1. Instanatiate an Employee object and only fill in the relative 
information?  Keep in mind that this could be just employee name and 
location on the search results screen and then when the user chooses 
which employee to view I need to get all of the employee information.

2.  Instantiate an Employee object and fill out all the information even 
though you won't be needing most of it on the search results screen?

3.  Create 2 DTOs, one called Employee and one called EmployeeSearch 
DTO.  The EmployeeSearch DTO only stores what needs to be shown on the 
search results screen and the EmployeeDTO holds all the information for 
what needs to be shown on the detail screen?

4.  Something else...
I wouldn't make new DTOs/Value Objects. I'd just do number 1 above: 
"Instanatiate an Employee object and only fill in the relative
information?" OR sometimes 2 is ok if it's not a big query, that way 
could reuse your query. BUT, you also mention that are doing this based 
on a "search," often for that what you search on won't necessarily even 
be in the EmployeeDTO so I often DO make a SearchDTO to pass to my 
service layer. For example maybe you want to search on employees who 
have been hired before a certain date and after a date. You then would 
have a startDate and endDate in your searchDTO. I susually always end up 
with a searchDTO for when I need to capture criteria to search on. But 
if say for displaying a list of Employees that the user can pickf from.. 
I'd simply reuse the basic Employee object, even if it's only populated 
with a name and ID.

By the way, I recommend you look at iBATIS for this stuff. It really 
makes this stuff pretty easy http://www.ibatis.com/. I even have a small 
example lesson showing it in use (although it needs to be updated)

Re: [OT] Open/free SQL Query Wizard

[James Mitchell]

May not be what you are looking for, but I use DbVisualizer.it simply
rocks!!

Is there a reason it needs to be web-based?  Remote access??

If DbVis doesn't work for you, I can give you a copy of a little jsp that I
put together that works with DB2.  It displays 3 text area inputs, 1 for
straight sql (select), 1 for straight sql (update), and one that you can use
hql (Hibernate SQL).  Below that it lists, and links the meta info for the
specified database.  As you click, it drills down.  Click a schema, it shows
the tables.  Click a table, it shows the rows.  A little crude, but
functional.

Anyway, just thought I'd offer.

RE: [OT] DAO ... where to draw the line?

[Robert Taylor]

Strategy 3.

I would basically have a DAO that handles the search query
and returns a collection of value objects for the related use case.
When the user clicks on a specific employee, then render the
details using your employee DTO.

As far as patterns are concerned you may want to take a look
as the ValueObjectAssembler pattern or the TransferObjectFactory 
patterns.

Re: html:text - want to set disable= to a bean value

Stuart Guthrie wrote:
Hi there, 

What I'm trying to do is re-use the same jsp for ADD/UPDATE modes. In
order to do this, certain field attributes will be different depending
on the modes and sometimes even on the user's security credentials or
the 'status' of the customer row.
To this end I need to pass in the form bean whether a particular field
is disabled or not
I usually don't like to have my formBean take care of holding this 
information. Not that it's necessarily bad, I just sort of like having 
my form beans as dumb as possible and only maintain form captured 
information.

What I do in the above is base what to display on a "userAction" which 
actually ends up corresponding to my dispatch Action method name. This I 
will sometimes add as an ActionForm property (ie String userAction ).

I then control the dispaly based on this userAction ( "update", "add"). 
You'll end up with a bit more verbose code but I find it easier to 
maintain.. so for example

You might have a case where if you are doing an update you can't update 
the User Name but can update other fields:

Name:

  
 
  
  
 
  

If you really want you can do your approach though but you'll have to 
use the html-el tags

Then you can do:

where customerCodeEnabled would correspond to "true" or "false" and be 
set accordingly. I don't like this approach though because you'll end up 
having to code a bunch of these for different fields and you've made 
your backend responsible for figuring out how to display the info on the 
page ( he he I say I don't like this, and now I'm on a project where the 
whole application is going to be coded by meta-data to tell the front 
what to display.. but still in theory I don't like it:)

Does this work for you?


I had an app with similar requirements. IIRC, I solved it by doing the 
following.

In the JSP first define the FormBean that contains the boolean values:


then access the boolean fields for each form field like so:


Hope that helps.

Anyone else experiencing duplication of tag contents with JSTL?

e.g.


  

  



 where:

form.title=Log new {0}
person.form.name=Person

Results in "Log new Person" the first time you open the form and "Log
new PersonPerson" the second time and "Log new
PersonPersonPersonPersonPerson" the n'th time.

Any suggestions?

Re: Tiles breaks my page that uses logic:iterate

[Niall Pemberton]

OK so post the bits of your struts-config which show the forms and action
mappings for

1) The action which renders the page
2) The action the form will post to (i.e. "/TilesSaveInputs")

error code 404 not used in IE

[lixin chu]

Hi,
MS IE has default setting:
 Tools->Options->Advanced->Browsing->"Show friendly
HTTP error message"

When it is checked, the IE default error page is used
not your own 404 error page.

How can I change the http status code in Struts
application so that my own 404 page is used ?

thanks

JSTL duplication of tag content

[Johan Wasserman - BCX - Infrastructure Services]

Anyone else experiencing duplication of tag contents with JSTL?
 
e.g.


  

  


 
 where:
 
form.title=Log new {0}
person.form.name=Person
 
Results in "Log new Person" the first time you open the form and "Log
new PersonPerson" the second time and "Log new
PersonPersonPersonPersonPerson" the n'th time.
 
Any suggestions?

Re: [OT] DAO ... where to draw the line?

[Matthew J. Vincent]

LAST .  I promise!
Thanks!
Hi all,
Thanks for the info.  Here's another issue.
What if I have an employee search screen that wants to show only some 
of the information of an employee (not all).  What do you do then?
1. Instanatiate an Employee object and only fill in the relative 
information?  Keep in mind that this could be just employee name and 
location on the search results screen and then when the user chooses 
which employee to view I need to get all of the employee information.

2.  Instantiate an Employee object and fill out all the information 
even though you won't be needing most of it on the search results 
screen?

3.  Create 2 DTOs, one called Employee and one called EmployeeSearch 
DTO.  The EmployeeSearch DTO only stores what needs to be shown on 
the search results screen and the EmployeeDTO holds all the 
information for what needs to be shown on the detail screen?

4.  Something else... Another pattern, etc?
Thanks!
Matt

hi matthew,
I wont say that you go with one or other of your approaches.
It depends upon type of assosciation that 2 entities may share. They 
may have aggregation or composition relationship. Depending on that 
your DAO implementation will decide that you need to get ONLY id or 
the composite objects.

Let me explain.
Say you have class named ORDER ad ORDER_DETAILS. (consists-of 
relationship) Order without order details is nothing. So you may get 
the OrderDetails object as well when you get Order.

Now say you have EMPLOYEE and DEPARTMENT. (has-a relationship) 
EMPLOYEE *may* still exists with or without department. So you may 
get only id of department and later fetch the department.

Think in employee table, you have relationship (reports-to). If you 
specify this relation as composition, you may go on fetching the 
objects all the way up to the organization chart ;-)

Do i make sense?

Subject: [OT] DAO ... where to draw the line?

[OFF TOPIC]
I know this is a struts forum, but as struts developers using DAOs, 
where do your DAO implementation draw the line?
For example:

Let''s say I have three tables:
Employee (contains employee_id, employee_name,  and dept_id)
Department (contains dept_id, dept_name, loc_id)
Location (contains loc_id, location_name)
How deep do your classes go to replicate the data?
Do you do this...
public class Employee {
   private int id;
   private String name;
   private int deptId;   // just the id
   // .. implementation details
}
or do you do this
public class Employee {
   private int id;
   private String name;
   private Department dept;  // all of the data
   // .. implementation details
}
and so on and so on.   Class Department has the same type of 
problem.  Does it hold just the id for location or a variable class 
Location?

Should DAOs just fill in the id (keys) so it is up to the 
application using the DAOs to get the Employee class, then the 
Department class, and the the Location class like:

Employee emp = EmployeDAO.getEmployee(1);
Department dept = DepartmentDAO.getDepartment(emp.getDeptId());
Location loc = LocationDAO.getLocation(dept.getLocId());
System.out.println(emp.getEmpName() + " works in " + 
loc.getLocationName());

or
Employee emp = EmployeDAO.getEmployee(1);
System.out.println(emp.getEmpName() + " works in " + 
emp.getDept().getLoc().getLocationName());

Now this is just a simple example, but where do you draw the line?  
It's possible to go on and on and on and cycle back to employee...

Any thoughts, links, tips, best practices, whatvere would be helpful!
Thanks!
Matt

html:text - want to set disable= to a bean value

[Stuart Guthrie]

Hi there, 

What I'm trying to do is re-use the same jsp for ADD/UPDATE modes. In
order to do this, certain field attributes will be different depending
on the modes and sometimes even on the user's security credentials or
the 'status' of the customer row.

To this end I need to pass in the form bean whether a particular field
is disabled or not

I've searched the archives to no avail. I'm trying to set the disable=''
attribute on the html:text tag to a value in the form bean I'm passing
in.

eg:

formbean.isCustomerCodeEnabled()

returns a boolean true/false

formbean.getCustomerCode()

is the value of customer code.

I'm trying (hoping) to do something like this:



I've tried lots of different approaches, all failing. I've also scanned
the examples to no avail.

Latest attempt is:



<% boolean customerCodeDisabled=(!customerCodeEnabled); %>


Which fails with:

customerCodeEnabled = null; [javac] ^ An error occurred at line: 87 in
the jsp file: /CustomerFormWindowMainTabBody.jsp Generated servlet
error:
[javac]/home/sfg/javadev/jboss-3.2.3/server/default/work/MainEngine/localhost/pimsweb/CustomerFormWindowMainTabBody_jsp.java:175:

Tiles breaks my page that uses logic:iterate

[Janne Mattila]

I have a simple page for editing some form properties. It works. There's a 
select box, a multibox, single-select select and a text input field. Now I 
tried to "Tiles-ify" it, just using Tiles to add some silly decorations 
around the actual form. Using tiles seems to break the form, the exception I 
get is

the JSP page for the form looks like:


 
 
 Select + optionsCollection:
 

 
 Multibox:
 
 
   
 
   
   
 
 Single select + optionsCollection:
 

 
 Plain text field, validated using validator
 e-mail:
 
 Back
 
 

The part which breaks the page is the multibox, it's iterator and use of 
iterator's choice object. If I take that part out the page works fine with 
Tiles, I can make the selections etc.

The page works fine also with the multibox as long as I do not use Tiles. 
With tiles I use the same Actions, JSP code for forming the output is 
straight copy-paste, there's no difference with the action definitions in 
struts-config.xml. The only difference is the use of Tiles. I wonder what 
about Tiles causes this to break?

Are there any "commonly known" techniques to do this smoothly with

What about Container Managed Authentication? 
It's part of J2EEs standard (so it's not Struts specific)
and it allows you to configure server to protect your pages
as you've described above.

See http://jakarta.apache.org/tomcat/tomcat-5.0-doc/realm-howto.html
for Tomcat5 configuration.
Or use securityfilter on http://securityfilter.sf.net, a servlet filter 
which mimics container managed security in case you do not want to 
change your container's settings.

Re: Modifying Tiles definitions dinamically

[Leandro Melo]

I'm not sure if i get it right, i still have a couple
doubts.
Take this definition:


...

  

...




Naturally i got a login page, would i have to redirect
the login (or just forward the login) to  this
"TilesAction" and then manipulate my definition and
insert the real jsp page i want???

I have never heard of this "TilesAction" (haven`t been
dealling with struts for long time), but is it
possible to some post some bib reference (or web
reference) where i can learn how to work with it???

If it`s easy, maybe a little piece of code would also
work.

Thanks,
Leandro

RE: OC4J and struts issue

In jsp page if you are including the tag lib files like this

<%@ taglib uri="/tags/struts-bean" prefix="bean" %>
<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>

your taglib code in web.xml file should be like this

Re: Still need help with layered Map iteration in JSP

[Kris Schneider]

It's certainly not a bad idea to grab a JSTL book, but the spec itself is quite
readable and full of good information:

http://jcp.org/aboutJava/communityprocess/final/jsr052/

The only JSTL book I've even partially read is "JSTL in Action" by Shawn Bayern
and I have no reservations recommending it. There are also plenty of web
resources available:

http://www.javaworld.com/javaworld/jw-02-2003/jw-0228-jstl.html
http://www.onjava.com/pub/a/onjava/2002/08/14/jstl1.html

Re: Still need help with layered Map iteration in JSP

Kris, once again you have helped me get my work done. bean:size did the 
trick. I was looking over and over again for a JSTL tag or expression to 
do this; I probably never would have thought of bean:size.

OK, I'll take ANY WAY TO DO THIS AT ALL.
I have a c:forEach over a Map. The value for each key in the Map can be 
an array of objects, or I can make it a List. I don't care at this point.

All I want to do is get the length of this array or List, before I start 
iterating over *it*, during the current iteration of the Map. I am told 
that I access the array or List like this:

1) Given this Map iteration:


2) access the value of the current Map entry (which will be either an 
array or a List) like this:
${currentMapEntryWhichIsBothAKeyAndAValueTogether.value}

But I have tried all of these, none of them work:






Not that they would have worked, because I was merely guessing in every 
case.

This is the type of thing that makes me sorry I ever got involved with 
tag libraries.

I have a Map of Lists. I didn't invent this. This is a common structure 
to use in Java. So someone please show me a single document that tells 
you how to work with JSTL tags (or any other tags) to do such a simple 
thing as to do a nested iteration of a Map of Lists or a Map of arrays!

Here is the Java equivalent of what I need to do:
//Map, stored as request attribute, has String keys, MyClass[] values
Map map = getMapWhichIsARequestAttribute();
Iterator i = map.keySet().iterator();
while (i.hasNext()) {
   String key = (String) i.next();
   MyClass[] values = (MyClass[]) map.get(key);
   int size = values.length; // *HOW DO I GET THIS VALUE USING TAGS?*
   if (size > 0) { // *HOW DO I IMPLEMENT THIS TEST USING TAGS?*
if (size > 5) {
//do setup for a big array
for (int x = 0; x < size; x++) {
//do output for each item in array
}
}
<>else {
<>//do setup for a small array
for (int x = 0; x < size; x++) {
//do output for each item in array
}
}
   }
   else {
   //no records found for this key
   }
}

Failing that, I would appreciate it if someone could show me how to do 
this using Struts tags. If I had used scriptlets, I would have been done 
hours ago.

Thanks,
Erik

I have a c:forEach where "items" refers to a Map, and "var" refers to

The value for each Map entry is an array. How do I switch on the

But I get a syntax error; it says I supplied the "." operator with an 
index value of type "java.lang.String" to be applied to an array, but 
that the value cannot be converted to an integer.

Is there some sort of way I can use "items.length" or "items.size" or 
something similar? More importantly, WHERE IS THIS DOCUMENTED?

I have searched the Internet for decent documents on JSTL and cannot 
find a simple complete guide to tag usage -- something similar to what 
Struts has for its tags. For example, where is a document that 
explains what you can do with "var", "varStatus", "items", etc. on a 
c:forEach tag, and covers all the tags? The Sun web services tutorial 
does not do this, it only gives examples.

If you are populating here, and do not have the form specified, then how
is the form getting sent to the page?
I typically set the name parameter, and validate=false when going
through my populate actions.

- - 

By using HttpServletRequest.setAttribute("myStringList",
dataObjectArray); name-attribute, as far as I know, defines the form
where we want to read the data, it's not necessary in actions where you
just throw some stuff to request.

Re: Accessing Session attribute from action

[Erik Weber]

Implement a checkLogin method in a base Action class that returns a User 
object or similar, whatever you need. This method takes an argument of 
type HttpServletRequest and looks for the User object in the request's 
HttpSession. Your Login Action would set this attribute, and your Logout 
Action would remove it.

Make all your actions extend the base Action class, then you can 
retrieve your User object (if there is one) from any Action. You can 
also access the objects in JSPs since they are just Session attributes. 
For example:


 

Hope that helps,

RE: handling multiple independent window

[Kailash Vasani]

Thanks Antonio,

this seems to be simpler solution.

for benefit of all, we have opted to update RequestUtil class of struts so
that all the JSPs would now
be passing one parameter always. Hence we r doing the same thing, but in
slightly differnt way.

I wonder whether struts ppl had considered similar requirement or not. I

I think you could use a request-scope bean that contains an ID referring
to one item in a session-scope collection (here I mean an array, a Map, a
List...).
Then expose your item in a page-context bean (using bean:define) and use
it in the rest of the JSP page.

Still need help with layered Map iteration in JSP

[Erik Weber]

OK, I'll take ANY WAY TO DO THIS AT ALL.
I have a c:forEach over a Map. The value for each key in the Map can be 
an array of objects, or I can make it a List. I don't care at this point.

All I want to do is get the length of this array or List, before I start 
iterating over *it*, during the current iteration of the Map. I am told 
that I access the array or List like this:

1) Given this Map iteration:


2) access the value of the current Map entry (which will be either an 
array or a List) like this:
${currentMapEntryWhichIsBothAKeyAndAValueTogether.value}

But I have tried all of these, none of them work:






Not that they would have worked, because I was merely guessing in every 
case.

This is the type of thing that makes me sorry I ever got involved with 
tag libraries.

I have a Map of Lists. I didn't invent this. This is a common structure 
to use in Java. So someone please show me a single document that tells 
you how to work with JSTL tags (or any other tags) to do such a simple 
thing as to do a nested iteration of a Map of Lists or a Map of arrays!

Here is the Java equivalent of what I need to do:
//Map, stored as request attribute, has String keys, MyClass[] values
Map map = getMapWhichIsARequestAttribute();
Iterator i = map.keySet().iterator();
while (i.hasNext()) {
   String key = (String) i.next();
   MyClass[] values = (MyClass[]) map.get(key);
   int size = values.length; // *HOW DO I GET THIS VALUE USING TAGS?*
   if (size > 0) { // *HOW DO I IMPLEMENT THIS TEST USING TAGS?*
if (size > 5) {
//do setup for a big array
for (int x = 0; x < size; x++) {
//do output for each item in array
}
}
<>else {
<>//do setup for a small array
for (int x = 0; x < size; x++) {
//do output for each item in array
}
}
   }
   else {
   //no records found for this key
   }
}

Failing that, I would appreciate it if someone could show me how to do 
this using Struts tags. If I had used scriptlets, I would have been done 
hours ago.

Thanks,
Erik

The value for each Map entry is an array. How do I switch on the

But I get a syntax error; it says I supplied the "." operator with an 
index value of type "java.lang.String" to be applied to an array, but 
that the value cannot be converted to an integer.

Is there some sort of way I can use "items.length" or "items.size" or 
something similar? More importantly, WHERE IS THIS DOCUMENTED?

I have searched the Internet for decent documents on JSTL and cannot 
find a simple complete guide to tag usage -- something similar to what 
Struts has for its tags. For example, where is a document that 
explains what you can do with "var", "varStatus", "items", etc. on a 
c:forEach tag, and covers all the tags? The Sun web services tutorial 
does not do this, it only gives examples.

HTML Filtering?

[Mike Elliott]

I have a situation where I need to populate a table with values.  Sometimes 
those values are empty.  Mozilla, for reasons outside of this discussion will 
not fully render a table datum that is empty; that is, it will render nothing 
(correctly) but also not render the border of the table datum either, if the 
content is empty.

Normally the workaround for this is to put a non breakable space ( ) in 
the table datum to get Mozilla (or Netscape, for that matter) to render the 
table datum with all surrounding borders.  However, Struts makes that 
difficult.

If I use a  tag, I can specify filtering off to allow the   
non breakable space to appear.  That will, however, prevent the filtering of 
non-empty items as well -- which might not be such a good idea.  Or, I can 
turn on filtering which will cause oddball elements to be rendered correctly, 
but will prevent the   from being a non-breakable space.

So . . . what I need to do is perform the filtering beforehand, then set the 
bean to render the property with no filtering (filtering="false").  That 
means I need to do my own filtering.  Yes, I can write my own HTML filtering 
routine, but . . . there must be something already out there - probably part 
of the commons-beanutils jar file - that already does such filtering.  I'd 
much rather use that than roll my own.

Anyone know of such a routine?  That is, a routine invokable from within an 
arbitrary class, that takes a chunk of text and renders ampersands as &, 
left angle brackets as < etc.?

Re: Overwritting RequestProcessor, how to???

[Niall Pemberton]

Although you haven't specified the TilesRequestProcessor in the 
element the TilesPlugin automatically changes it to TilesRequestProcessor.

If you do however specify your own custom RequestProcessor in the
 element and you use tiles then if it doesn't extend
TilesRequestProcessor then the TilesPlugin will throw an exception.

So, in short,  you are using TilesRequestProcessor and your custom version
needs to extend that one.

RE: Mapping ActionPath to a method in DispatchAction

[Amit Kumar Sharma]

Try lookupDispatchAction instead of DispatchAction and have a message
resources(applicationresource.properties) for the mappings...that you
way you can achieve multiple submits as well as no need to check for the
method parameter.
You need to check for the html:submit code for that.

What about Container Managed Authentication? 
It's part of J2EEs standard (so it's not Struts specific)
and it allows you to configure server to protect your pages
as you've described above.

Re: Modifying Tiles definitions dinamically

[brenmcguire]

think the best (and the most elegant) way to make dynamic tiles is by
using TilesAction. This because this class has knowledge of the use of
Tiles.
So write your TilesAction (it is similar to a plain Action, except of some
more parameters in the "execute" method). In the "execute" method put your
code that can distinguish between different users and for each one forward
to a different JSP page, that will be your "real" tile.
Obviously map your actions in struts-config.xml just the same way as
normal actions.
Then put a definition like this (I am using your example):


  
  
  
  
  
  
  


Hope it helps.
Ciao
Antonio

P.S. In fact in this example a normal Action can be used, but I suggest to
use TilesAction because that class can manipulate the definition itself
(please people working on Struts, correct me if I am wrong).

RE: Action Servlet not getting called.

[Jitender K Chukkavenkata]

Hi Veera,
You have used an identifier called employees for logic:iterate name 
attribute.   The name should be a valid bean name defined in any scope.  I 
guess you are giving a wrong reference.  Try giving a valid bean reference 
that exist in any scope.

Re: Need help with layered Map iteration in JSP

[Erik Weber]

I have a c:forEach where "items" refers to a Map, and "var" refers to 
the current Map entry.


The value for each Map entry is an array. How do I switch on the length 
of this array? I tried this:


But I get a syntax error; it says I supplied the "." operator with an 
index value of type "java.lang.String" to be applied to an array, but 
that the value cannot be converted to an integer.

Is there some sort of way I can use "items.length" or "items.size" or 
something similar? More importantly, WHERE IS THIS DOCUMENTED?

I have searched the Internet for decent documents on JSTL and cannot 
find a simple complete guide to tag usage -- something similar to what 
Struts has for its tags. For example, where is a document that explains 
what you can do with "var", "varStatus", "items", etc. on a c:forEach 
tag, and covers all the tags? The Sun web services tutorial does not do 
this, it only gives examples.

Thank you,
Erik

How can I refer to the index of the current iteration with c:forEach 
(analogous to the indexId attribute to logic:iterate)?

Thanks,

Quoting Erik Weber <[EMAIL PROTECTED]>:


I could use some Struts-EL/JSTL tag help, please.
I have a Map with each entry having a String as the key and a bean 
array as the value.

I need two iterations, one nested inside the other.
For the outer iteration, I want to iterate the keySet of the Map. 
I don't know what the keys are going to be or how many there will be.

Within that iteration, for each key in the keySet, I need to 
iterate over the buckets of the array that is the value for that key.

To make this more clear, let's say I will produce a table of 
tables, somewhat like this:
















































Could someone show me some skeleton JSTL or Struts-el code?
I would appreciate it very much,
Erik

Subject: If not logged in, login and redirect do requested page scenario.

Hi,

Some pages in the site I'm working on should be available only for users who
have previously logged in, but links to them may appear on pages that area
accessible for anybody.

I'm trying to implement a scenario in which if the user who has not logged
in clicks on a link to a page "for logged in users only"  should be
redirected to "login page", and then if the login operation succeeds another
redirection takes the user, to the page that was originally requested.

Are there any "commonly known" techniques to do this smoothly with Struts??

I did it as follows...

All links to pages "for logged in users only" go throuth one action say
"LoginAndRedirect" so in JSP they look like



The LoginAndRedirect action first checks if there is an instance of
OnlineUser (which is a simple JavaBean) in the session (its presence
indicates that the user has already logged in) If the OnlineUser is not
found, the value of the FORWARD_TO parameter is stored in session and the
LoginAndRedirect action forwards to login.jsp (global forward) where the
user gets his chance to authenticate. If the attempt to login succeeds, the
OnlineUser is placed in the session and the request is forwarded back (again
through the global forward) to the LoginAndRedirect action which this time
finds the OnlineUser in the session as well as the FORWARD_TO param. All
"for logged in users only" pages are defined as forwards of LoginAndRedirect
so its final action is sth like...

return forward.findForward(session.getAttribute("FORWARD_TO"));

I'm aware that with this approach I must also prevent somehow "not logged
in" users from accessing the "forbiden pages" directly - thay can just type
the URL in the browser and get where they should not :)

Any suggestions of making this in a better way will be appreciated!! :)

Regards
Chris

RE: Action Servlet not getting called.

[Veerabhadra Rao R]

Hi,

I am getting the following error while running a sample struts
application from MasteringJakartaStruts pdf file.

javax.servlet.ServletException: Cannot find bean employees in any scope
at
org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContex
tImpl.java:478)
at
_jasper._pages._employeelist_jsp._jspService(_employeelist_jsp.java:604)

The Employee bean is calling in Action class, on success that action
class is forwarding to employeelist.jsp page.

In jsp page I am using iterator to display the results.




I have added following action mapping to struts-config.xml for a page.


















Thanks & Regards

what does tomcat log returned?
does it throw error or a blank page?

is it because of space after this dot?

  type="mascot.workqueue.action. SummaryAction"
