Validator - Javascript question

[Ratnakar Parakala]

Hi, 

I tried to write custom validation rule called "identical". But, if I give oIdentical 
= new identical(); I didn't get any client side alert messages. Hope this statement 
doesn't generate necessary javascript code when the rule is configured and executed. 
I'm using Struts 1.2.1 (Beta). Could sombody tell me the use of oTwoFields = new 
twofields(); statement and how struts uses this statement to generate client side 
javascript. 

Thanx in advance, 

Ratnakar

Re: Struts - passing unicode parameter from jsp to action

You should better call request.setCharacterEncoding() in
a filter or overriden ActionServlet's method process().

Request parameters are read when ActionServlet prepares form
instances - it happens before your Action is called.

> difinition on my jsp page <%request.setcharacterEncoding("UTF-8");%>

I think you have no reason to put this call in your JSP.

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

[Navjot Singh]

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

Re: HTTP Compression (Struts)

[Navjot Singh]

unless you have special reasons why do you wish to burden struts or web 
app with everything?

why not use mod_gzip with apache and put tomcat/xyz behind apache?
it gives good compression and you can define compression or no 
compression based on mime types.

Struts - passing unicode parameter from jsp to action

[Masoud Kalali]

hi friends,  i have problem with sending unicode parameter to my action 
from jsp page
I  use post for sending parameter to action
and also add
(request.setCharacterEncoding("UTF-8");
to my action before reading parameter from it , also i add two 
difinition on my jsp page <%request.setcharacterEncoding("UTF-8");%>
and  which both of them set content and encoding of my jsp 
pages to utf-8 but i istill could not use my parameter , thier encoding 
seems to be " ISO  Latin-1 " . while i type unicode characters in my 
text are at jsp page.
I use Websphere as APPS , is it a problem of Websphere?

RE: I have a form spread over several pages. The user fills out each section in progression. I am using a dispatch action and each page calls the same function i.e. processForm. I want struts to validate each submission but I cannot change the input page

[Kataria, Satish]

Ok I got what u r saying.
What I am trying to say is that you have a single Action class but
multiple action mappings(one per page) and since you can configure input
setting at action mapping level therefore it will solve ur problem
Structure of code will be

public class Actionclass extends org.apache.struts.action.DispatchAction
{
--method1 for page1
--method2 for page2
---



And so on
}



Struts-config.xml



And so on for each page


Hope it helps

I get you. This is what we have currently, the problem is that when the 
validation ( on say page 5 ) fails the user gets sent back to page one 
because only one input page parameter is allowed per action definition 
(in struts-config).  It seems to me you still have to define a separate 
action path for each page you want validated (though it would map to a 
particular function in your DispatchAction ) .

Page expired warning on history.go(-1) Internet Explorer

[Ajay Katre]

I have a struts action URL http://myhost.mydomain.com/myapp/myaction.do

It is a non-secure page. The form action is HTTP-POST.

On submitting this form it displays the results. On results page I've a Back button 
with javascript: window.history.go(-1); 

Sometimes it gives "Warning: Page has expired" error. This is not consistently 
reproducible.

Error has been confirmed to be intermittent with Internet Explorer 6.0 browser.

Any information about this error and fix.

Sorry, I don't know anything about Eudora.  But are you talking about

No, the key bit of magic it looked like you were missing was the onsubmit bit of magic.
So, whatever puts the validateBlahForm(this) on the page is what you want.. and then 
call it.. Considering that SIA is an interesting mix of 1.1 and 1.2 you might want 
to look at the javascript being generated and make sure the you're onsubmit is calling 
the right javascript function.

html:javascript problem

[Erik Weber]

I am using the validator plugin, specifying all my validation in 
validation.xml.

I want to use the automatic javascript generation feature to add 
client-side validation.

My form page is basically like this:
. . .

. . .

When the page is rendered, I can view source and see the javascript 
function is seemingly properly rendered, and the function name matches 
up with that called in the onsubmit attribute, yet if I submit a blank 
form, I don't get any alerts -- the form submits.

I'm not sure how to debug this since the javascript is generated 
dynamically; I suppose I could edit validator-rules.xml to put alerts in?

Anything I am obviously doing wrong or forgetting here? I'm not very 
good with javascript, but I was hoping to avoid pasting the function 
because it's quite lengthy.

I tried moving the html:javascript tag around to different places -- at 
the top of the page, just above the form, just inside the form, doesn't 
seem to make any difference. I do have other (non-generated) javascript 
functions working.

If you don't see anything wrong so far I'll paste a snip of the page

Try this instead of html:errors:








If that works then you can mangle the html however you want of course.

We have the same setup.. the differenece being that mines working,and yours isn't.  So 
if we start looking for differences.. one is that i'm using the code above instead of 
.  I would have sworn that's what I was using for dumping my error 
messages.  Another would be the way we're generating these messages... I use the 
Struts validation stuff, so it does it all automagically.

Re: Multiple image tags

[Michael McGrady]

You got it, Leandro.
You end up doing with this solution what the LookupDispatchAction does with 
less overhead, less of a footprint, and without all the coupling to the 
framework.  I put the solution on the Struts wiki, and a pretty good 
programmer actually suggested using this solution and adding it to 
LookupDispatchAction.  That really confounded me.

What's your first language?  Don't say Java!  LOL

DispatchAction and LookupDispatchAction does. This way
your solution certainly works perfectly.
Is that it?

Re: Importing context with Struts

[Leandro Melo]

Jim,
as i said i have a page with only one line of code,
wich is the error page.
It only has this:



Suppose now we want to register a company in the
application, i got then an form with all the necessary
inputs in a page registercompanycustominforeq.jsp.
Here's the page for registering.


  <%@ include
file="/functionalBlocks/companyHTMLcomponent.jsf" %>


The user sees the following definition when he's
filling the company info.

  
  
  


If your remember, the base class ".PartyPlace" has
already inserts the error page.

I don't know what you meant about "WHat scope are
your errors beign put in?". How do i find out that?

The only thing i know is if the user request is
blocked in validation, my html:errors tag doesn't show
anything.
BUT, if i place the html:errors tag inside the page
with the registercompanycustominfo action, it works
fine.
In other words, if i modify my
registercompanycustominforeq.jsp to this:

  
  <%@ include
file="/functionalBlocks/companyHTMLcomponent.jsf" %>


Everything works!!! The errors tag works.

Re:

You might be getting a ClassCastException, because, you might be using
Struts 1.1, and adding a ActionMessage to ActionErrors and using the
 tag. The tag assumes ActionError object, so, when it
tries to cast your ActionMessage to ActionError, that's where you run
in to ClassCastException. So, instead of  use
 in the way shown below.


errors.add("name", new ActionMessage("user.name.empty.error"));

In jsp use,

I admit this is overly restrictive, but I don't know how to get the

For SQL destined test, I disallow \ and '.
   

If I'm doing the SQL myself, I always use prepared statements:
 

Absolutely. PreparedStatement is always the way to go, depending on the 
database you'll get a couple of performance gains also.

 String streetAddress = "..."; // String may have "\" and "'" characters in it
 PreparedStatement stmt = conn.prepareStatement
   ("UPDATE CUSTOMER SET STREET_ADDRESS=? WHERE CUSTID=?");
 stmt.setString(1, streetAddress);
 stmt.setInt(2, custId);
 stmt.executeUpdate();
and let the JDBC driver take care of getting the sensitive characters
escaped as needed.
 

In fact the drivers should not (again implementation specific) need to 
do any escaping, the statement and data are seperate entities. The 
statement will still contain ? (or equivalent) in the rdbms.

There is nothing fundamentally wrong with what you describe. If you have 
conflicting locks or changes between transactions (typically 
connections) then any DML statement can potentially hang up. What 
database are you using? Are you testing it with just one session? My 
first suspision would be the connection pooling, especially if this is 
failing with only a single session active. Perhaps try disabling that 
for a test.

More then likely.  If you look at the 1.2 javadocs at

One main difference between the method in the archive and my 
method is that
I put the "errors" object into the session instead of the 
request.  The
reason is that all my actions redirect to their respective 
.jsp pages to
avoid the user re-running an action simply by refreshing the 
page (e.g. a
'create' action). 
I think that anything stored in the 
request is lost by
the time the action is redirected.  I put "errors" in the 
session instead.
One problem with this is that the "errors" object remains in 
the session so
any subsequent visits to the page display errors.  Since an 
error redirects
the user right back to the same page, I think I may remove 
the "errors"
object from the session as soon as the form is submitted.

My questions are:
1) Do I need to put "errors" in the session so that it survives the
redirection long enough to be displayed?
   

More then likely.. try it and see.  You're reasons for redirection kind of bother 
me.. I've never run into a situation where a refresh submits a form twice, but then 
again I haven't run into every situation.
 

2) Do I need to use  inside an  tag to output
messages?  Is it the only way?
   

Nope, you can use 

 

3) Is it considered bad form to use ActionErrors?  I don't 
want to build
dependencies on soon-to-be-deprecated stuff.
   

Depends... for struts 1.1 no, for struts 1.2 yes.  If you're planning on migrating 
soon... up to you.

When I converted a current app to Struts 1.2.x I'm sure it all still worked
with ActionError - I have now changed all ActionError to ActionMessage so
that I don't get all the "deprecated" warnings. Can you post your stack
trace with the ClassCastException?

More then likely.. try it and see.  You're reasons for redirection kind of bother me.. 
I've never run into a situation where a refresh submits a form twice, but then again I 
haven't run into every situation.

Depends... for struts 1.1 no, for struts 1.2 yes.  If you're planning on migrating 
soon... up to you.

That's one way to do it.  In support of this, Struts 1.2.x has what's called
"Session-scoped ActionMessages".  See the release notes. 
http://struts.apache.org/userGuide/release-notes.html .  
Another way is to pass the errors as a redirect parameter, which is what I
do.  I wrote some extension classes which I include in my projects for this
purpose.  If you're interested, lemme know.

The standard code I've seen actually has  because that's the tag
that comes with Struts, but  works, too, as you've discovered.

> 3) Is it considered bad form to use ActionErrors?  I don't want to build

ActionErrors will be deprecated in 1.2 and removed in a future version.  If
you're still using 1.1, though, I don't think you have a choice since the
methods these will only work with ActionErrors.

I found this in the struts mailing list archives which may be helpful to
you: 
http://marc.theaimsgroup.com/?l=struts-user&m=108757076826525&w=2

I'm also confused about the preferred method of displaying errors after the
deprecation of ActionError.  Armed with the knowledge from the archive I did
the following:

Here's the short version; code follows.  (Note: I'm using Struts 1.1)

In the action: I create an ActionMessages object called "errors". For each
new error I add an ActionMessage to "errors" with the field as the key
("username" in the following case).  I then store the ActionMessages object
as an attribute called "errors" in the session.  

In the .jsp page: I output each error next to its respective field in the
form.  Each error's key is the same as its field name.



Say we have a form with a 'username' field.

In SubmitFormAction.java :

public ActionForward execute(ActionMapping mapping, 
ActionForm form,
HttpServletRequest request, 
HttpServletResponse response)
throws Exception {

ActionMessages errors = new ActionMessages();

...

if ( isBad(username) ) {
errors.add("username", new ActionMessage("error.bad_username"));
}

...

if ( !errors.isEmpty() ) {
request.getSession().setAttribute("errors", errors);
return (mapping.findForward("error"));
} 

return (mapping.findForward("success"));
}

In form.jsp:

User Name: 





The output is:
User Name:  



One main difference between the method in the archive and my method is that
I put the "errors" object into the session instead of the request.  The
reason is that all my actions redirect to their respective .jsp pages to
avoid the user re-running an action simply by refreshing the page (e.g. a
'create' action).  I think that anything stored in the request is lost by
the time the action is redirected.  I put "errors" in the session instead.
One problem with this is that the "errors" object remains in the session so
any subsequent visits to the page display errors.  Since an error redirects
the user right back to the same page, I think I may remove the "errors"
object from the session as soon as the form is submitted.

My questions are:

1) Do I need to put "errors" in the session so that it survives the
redirection long enough to be displayed?
2) Do I need to use  inside an  tag to output
messages?  Is it the only way?
3) Is it considered bad form to use ActionErrors?  I don't want to build
dependencies on soon-to-be-deprecated stuff.

extending the html:select tag

[Wiebe de Jong]

I am having trouble extending the struts html:select tag, and I hope
somebody can help me.

Naill's example at http://www.niallp.pwp.blueyonder.co.uk/#errortag shows
how to extend the text tag. I used it to extend the password tag with no
problem.

However, when I use the same method to extend the select tag, I get a
runtime error. It seems to die even before the constructor is called.

So, how do you debug tags and does anyone have a solution to make this work?

RE: Taglibs generating lots of warning messages

[David Friedman]

I used to turn on/off the logging for various modules (or everything) using
the commons logging.   Check that out.  I used SimpleLog and turned
everything off.  Then, I used debug or info for the modules I'm interested
in.
http://jakarta.apache/org/commons/logging

I think I turned it all off in my simplelog.properties file using:
org.apache.commons.logging.simplelog.log.org.apache.struts=none
But you could set it to "info", "debug", etc.

I setup up commons logging to use the simplelog by creating a
simplelog.properties file like so:

org.apache.commons.logging.Log=org.apache.commons.logging.impl.SimpleLog
org.apache.commons.logging.simplelog.defaultlog=debug
org.apache.commons.logging.simplelog.showlogname=true
org.apache.commons.logging.simplelog.showdatetime=true

David

No idea... tried to figure out how to reproduce this but couldn't.  Almost
sounds like one of the struts jar files is mildly corrputed, but don't know

Now, this wouldn't be so bad, but I can't seem to figure out how to
filter these out with log4j. I turned off all logging to stdout, but
these warnings still go to stdout. (and on to catalina.out making for a
nice large log file)

Does anyone know how to either fix what it's complaining about, or
prevent these messages from displaying? The tags seem to be working just
fine otherwise.

Thanks,
Andy

RE: Struts security/validation

[Wiebe de Jong]

Craig, both you and Jim suggested that I make use of prepared statements. I
implemented my SQL using strings because it is easier to tweak during the
development phase. 

Now that the project is in maintenance, moving to prepared statements is a
good idea. Probably help a bit in performance as well.

As for the XML/SOAP calls, using the serializer to create the character
entities would be good.

Thanks

If I'm doing the SQL myself, I always use prepared statements:

  String streetAddress = "..."; // String may have "\" and "'" characters in
it
  PreparedStatement stmt = conn.prepareStatement
("UPDATE CUSTOMER SET STREET_ADDRESS=? WHERE CUSTID=?");
  stmt.setString(1, streetAddress);
  stmt.setInt(2, custId);
  stmt.executeUpdate();

and let the JDBC driver take care of getting the sensitive characters
escaped as needed.

(Of course, if you're using a persistence tier abstraction like EJB or
JDO or JDBC RowSets or Hibernate or iBatis et. al., you don't need to
worry about any of this -- it all happens automatically for you.)

> For XML destined text, I disallow <, >, &, \, and ".

For XML, I use one of several strategies depending on the detailed
situation:

* Recognize that XML allows either " or ' as attribute delimiters,
  so if a string includes one kind, just use the other.

* Write or use an XML serializer that translates "&" to "&"
  and so on for me.

* If the XML I am writing is actually markup on a page, use
  JSF components ... JSF includes APIs that do all the escaping
  for you.

RE: Struts security/validation

[Zhang, Larry \(L.\)]

Oracle sql insert needs to escape apostrophes so that you can insert apostrophes. So 
in your case you may need a utility method to convert all your text containing 
apostrophes to some thing like ''.

Example: If your user enters "I like he's idea", when inserting to data base you need 
to convert it to be "l like he''s idea".

Hope this helps.

I had a similar problem, which I discovered when one of my users tried to
enter a street address containing an apostrophe. Since I use apostrophes to
delineate my text strings in my SQL statements, this caused a database
error. I fixed it by not allowing apostrophes to be entered into any of the
test fields.

I admit this is overly restrictive, but I don't know how to get the
apostrophe into my database otherwise. How would you do it Craig?

For SQL destined test, I disallow \ and '.
For XML destined text, I disallow <, >, &, \, and ".

Just thinking out loud for a moment ...

Cross site scripting attacks don't happen when sensitive characters
are inside an *input* field.  The problem comes if you *output* the
data without filtering for them.  That's why the Struts 
tag, for example, filters "<", ">", "&", and ";" for you unless you
explicitly tell it not to, so if you are diligent about how you copy
your database data to output pages, you can safely accept these kinds
of character in input.

I notice that Kishore Senji (one of the other respondents in this
thread) is using Google's Gmail, just as I am at the moment.  Since
this is a web application, it's a good thing that Googe isn't
disallowing the magic characters on input into a textarea, or else we
would not be able to participate in this conversation :-).

Is filtering input really the appropriate strategy for dealing with
this problem?  If successful it will certainly help, but the approach
strikes me as overly restrictive for most application needs.

If I'm doing the SQL myself, I always use prepared statements:

  String streetAddress = "..."; // String may have "\" and "'" characters in it
  PreparedStatement stmt = conn.prepareStatement
("UPDATE CUSTOMER SET STREET_ADDRESS=? WHERE CUSTID=?");
  stmt.setString(1, streetAddress);
  stmt.setInt(2, custId);
  stmt.executeUpdate();

and let the JDBC driver take care of getting the sensitive characters
escaped as needed.

(Of course, if you're using a persistence tier abstraction like EJB or
JDO or JDBC RowSets or Hibernate or iBatis et. al., you don't need to
worry about any of this -- it all happens automatically for you.)

For XML, I use one of several strategies depending on the detailed situation:

* Recognize that XML allows either " or ' as attribute delimiters,
  so if a string includes one kind, just use the other.

* Write or use an XML serializer that translates "&" to "&"
  and so on for me.

* If the XML I am writing is actually markup on a page, use
  JSF components ... JSF includes APIs that do all the escaping
  for you.

I'd change them to their HTML equivalents.. however I've found that using the prepared 
sql statements eliminates the interpretation problem you've outlined.

RE: Struts security/validation

[Wiebe de Jong]

I had a similar problem, which I discovered when one of my users tried to
enter a street address containing an apostrophe. Since I use apostrophes to
delineate my text strings in my SQL statements, this caused a database
error. I fixed it by not allowing apostrophes to be entered into any of the
test fields.

I admit this is overly restrictive, but I don't know how to get the
apostrophe into my database otherwise. How would you do it Craig?

For SQL destined test, I disallow \ and '.
For XML destined text, I disallow <, >, &, \, and ".

It can be appropriate, you might eventually need to turn off that filtering.  It may 
be possible to legitametley allow such characters.  The immediate example I can think 
of is content management.  You could jump through hoops ( ex. Wiki's) to not use html 
to mark up the input but why?
If you do it on input, you definitiely need more then just grepping on characters, you 
need to look at what the content is.  Looking for a

The strategy you lay out will probably work, but it's a lot of effort
and means you'll be forever patching new versions of Struts with your
custom changes.  Far better would be to get Tomcat to stop lying to
you about the incoming server name and port:

http://jakarta.apache.org/tomcat/tomcat-5.0-doc/proxy-howto.html

Solving the real problem will make your Struts apps work correctly,
along with every other web appication that is based on servlet
technology.  They will all assume that getServerName() and
getServerPort() return the right things.

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

[Wiebe de Jong]

When it comes to app architecture, I always recommend the Core J2EE Patterns
book. The Second Edition is now available and you can get an overview of it
at http://corej2eepatterns.com/Patterns2ndEd/BusinessObject.htm

In response to your question:

A DAO should only contain the SQL code for the
create/read/update/delete/find methods of one single database file or view.

The Business Object, which is new in the Second Edition, wraps the DAO and
manages the state and business rules for that one object. Remove any
business rules, etc currently in your DAO and move them to the associated
Business Object when refactoring.

The Application Service, which is also new in the Second Edition, manages
business rules across multiple objects (Business Objects and/or DAOs).
Remove any business rules, etc currently in your Session Façades and move
them to the Application Service when refactoring.

Leave the transaction control, database connection stuff, etc in the Session
Façade.

So, go with your first example. Employee and Department should each have
their own DAO. If Department is just a simple lookup table, you could
combine them at the Business Object level. If Department is complicated with
its own set of business rules, then make use of an Application Service.

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!

You can retrieve the logged-in username by calling
request.getRemoteUser() in some subsequent request.  For security
reasons, you cannot retrieve the password, unless your particular app
server provides some proprietary mechanism.

Tom,
Just as a quick FYI - this isn't WebSphere specific security, per se. My 
understanding is that this is all part of the servlet specification. 
Tomcat supports it, as does any other servlet container. So, if you're 
looking for some documentation on things like getting the username, or 
figuring out what roles the user belongs to - check the servlet 
specification, or any book you have that talks about the servlet spec.

It could be just what the error says --  needs a .  Since you
don't have any yet, you can comment out the validator plugin for now by
opening struts-config.xml and commenting out the last very last entry there,
which starts with:



With that uncommented, the app should deploy.  If it doesn't, send another
email.  :)

Once you play around with it and have a form to validate, put that back in,
add your form to the validation.xml file, and it should deploy fine.

This has been discussed before on this list... might want to try searching for the 
solution there.

Yeah you can I'm just surprised that the xml validator is being that much of a 
pita.  Oh well.   Like another poster said, in the strtusconfig.xml file, there's a 
section dealing with the validator, go ahead and comment it out.

html base tag

[Travis Stevens]

I have been using the struts html base tag.  Unfortunately, our new 
staging machine is done with a proxy pass.  This means that the URL 
being sent to the box in which the tomcat is located is changed and the 
base is then wrong.

For example:
www.outside_firewall.com/tomcat
is proxy passed to
www.inside_firewall.com/tomcat
which means when the page returns to the client, the base tag is

Currently the base tag determines the server via the following
1. Passed as parameter?
2. request.getServer()
I would like to add another step
1. Passed as parameter?
2. An init parameter in the ServletContext instance?
3. request.getServer()
In order to do this, I will add a field to Global entitled SERVER with 
value "server" which can be configured in web.xml.  I will then access 
that variable via the ServletContext in the BaseTag class.

Does this sound feasible?  Any other ideas?  Is this something I should 
submit to be added to struts?

RE: Problem depoying struts-blank.war

[Hubert Rabago]

- Resend: Not sure why the first one didn't show; apologies if this becomes
the second one  -

It could be just what the error says --  needs a .  Since you
don't have any yet, you can comment out the validator plugin for now by
opening struts-config.xml and commenting out the last very last entry there,
which starts with:



With that uncommented, the app should deploy.  If it doesn't, send another
email.  :)

Once you play around with it and have a form to validate, put that back in,
add your form to the validation.xml file, and it should deploy fine.

RE: Problem depoying struts-blank.war

[Kenneth Litwak]

Here is the validation.xml file. Do I need this?  A lot of this is new
to me.  What would I do to rebuild the war without this file, if I can
get away with not using it?  Thanks.

Looks the validation file is a bit wonky.  That would
WEB-INF/validation.xml, and something is out of order in it.  Which
should be easy to fix, just put things in the right order.  If they are
in the right order.

Semicolon and period are perflecty legitimate for a textarea input.  I use a filter, 
that goes through the parameters looking for select.*from.*  for a quick check, then 
do a second more detailed look before rejecting for a security violation.  I do the 
same thing for insert and update as well, as seperate checks, which gives me some idea 
how far into the attack they've gotten.
I would also do the same thing for a cross site scripting attack, if I had a check for 
it.. actually look for keywords before flagging antyhing.  Since I do a lot of 
internal web apps, I'm not as concerned about this as I would be if I had external 
sites.

Problem depoying struts-blank.war

OKay... I have the exact same setup, and validation works just fine with this setup.  
The one thing I'm not doing is the ${name} that you are, but that shouldn't make a 
difference at all.  WHat scope are your errors beign put in?  That could be an issue.

Here's my base layout:

If you do a search on compression in the user messages, at 
www.servlets.com, for example, you really don't get much.  There is the 
good one by Craig, which is enough.  But not much other than that except 
stuff about ant compression.

The short answer, as other have said is of course no.  However, it can be easier to 
deal with a form then grabbing the var from the request itself, depending on your 
definition of easy, especially with being able to dynamically genereate your forms in 
the strutsconfig itself.
In addition, if you already have a form for showing the full object, you can use it to 
just get the id.  Appfuse does this quite a bit.

No idea... tried to figure out how to reproduce this but couldn't.  Almost sounds like 
one of the struts jar files is mildly corrputed, but don't know for sure.

Now, this wouldn't be so bad, but I can't seem to figure out how to
filter these out with log4j. I turned off all logging to stdout, but
these warnings still go to stdout. (and on to catalina.out making for a
nice large log file)

Does anyone know how to either fix what it's complaining about, or
prevent these messages from displaying? The tags seem to be working just
fine otherwise.

Thanks,
Andy

Typically, I try to keep things as modular as possible.  This typically means that if 
I'm using JDBC, as opposed to Hibernate, I put the object graph together in the 
business layer, rather then try and do it in the DAO layer.  This allows me some 
flexibility in what I return back.  I can have a business method that will only return 
the employee, as opposed to the entire graph if my view only needs to see the employee 
and the entire graph might prohibitive ( time/space) to fully extract.

If you put everything into the DAO it can be somewhat more troublesome to do, possible 
certainly, but it always seems to me that how much data you pull back is a business 
requirement related to the server power (memory/speed) you have, not a function of the 
data itself.

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

[Matthew J. Vincent]

[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!

Re: Excel File Conversion

Data is available on the jsp page. I need to convert this to excel file
on click of a button. Is there any way in struts to do this?
If it you just want the page to display as is in Excel either
1) Use Tiles or Sitemesh and make sure your content opens in the Excel 
layout with the top of the layout having:

<% response.setContentType("application/vnd.ms-excel");
   response.setHeader("Pragma", "");
   response.setHeader("Cache-Control", "max-age=0"); %>
2) reuse the same JSP but have a test for an Excel flag at the top and 
create the same response header as above

If you need a 'true' Excel document I've been messing with JExcel and 
like it. http://www.andykhan.com/jexcelapi/  It's faster than POI.

By the way the two lines
   response.setHeader("Pragma", "");
   response.setHeader("Cache-Control", "max-age=0");
were needed to content with a bug in IE using Excel format across https. 
If you aren't use https you only need the first line
response.setContentType("application/vnd.ms-excel");

In your regexp, you can specify "<" & ">" entities as "<" and
">" respectively.

1) You can use a strategy similar to the one described in the below url
http://wiki.apache.org/struts/StrutsCatalogBaseAction

OR

2) You can also define a custom RequestProcessor and override
processPreprocess(HttpServletRequest request, HttpServletResponse
response).

[OT] "hidden" submit button

[Barnett, Brian W.]

Does anyone know how to create a hidden submit button? We're using images
for the buttons, but still want the "enter" key to submit the form. Is there
a better way to handle this? We tried a few things with css but it didn't
seem to work. (visibility:hidden and display:none will hide the button, but
"enter" does nothing.)

 

Thanks,

Brian

Try and see what the value of the parameter on the page is in the

1.   The value of the hidden parameter begins with null and is not being reset.
2.   The value of the hidden parameter begins not null and is set to null.
3.   The name of the hidden parameter is the same as the parameter 
attribute in your action mapping.
4.   The name of the hidden parameter is not the same as the parameter 
attribute in your action mapping.
5.   The names of the parameters in your action mapping, your form and your 
ActionForm are consistent.
6.   The names of the parameters in your action mapping, your form and your

7.   Your actionscript is working as planned.
8.   Your actionscript is not  working.
9.   Your actionscript is not working as planned.

Or, one the preceding things is not happening.
I think your solution really looks way too complicated.  This is a lot of

JDK version to be used with Struts 1.1

[Christopher Kwiatkowski]

Struts 1.1.  We are currently operating at JDK 1.3 and I am experiencing

Re: Multiple image tags

[Michael McGrady]

Let me try again on this, Leandro, as much for myself as for you.  The 
LookupDIspatchAction, which I don't care for, only gives you one thing: a 
promise that the page author will have to use a particular name for the 
parameter name to be used in the Action for deciding which method to 
use.  That is it.  So, somehow the page author has to provide a value for 
the parameter name you specify in your LookupDispatchAction action mapping 
xml parameter attribute.  Thus, if you use parameter='method' in your 
action mapping xml, then you can know that using 'method' in your "hidden" 
values in the form will work.  You can also know, of course, that you then 
MUST use the request parameter 'method' in your form.  You can do the same 
thing without giving the parameter attribute of your action mapping any 
value at all.  You merely have to coordinate the page hidden parameter name 
and the parameter name mined in the Action.  The use of the parameter 
attribute in the action mapping MERELY forces the page author to conform to 
your requirements in the Action class, which then becomes the 
DispatchAction class or LookupDispatchActino class.

The whole point of using an image tag solution is to (1) get out of a 
Struts specific solution to this "age old" problem and to (2) provide a 
solution to the need to make a switch in the processing of an action.  The 
".x" and ".y" in the parameter names of an image tag operate just like the 
parameter attribute of the action mapping for the LookupDispatchAction and 
DispatchAction.  The difference is that it is not Struts specific and is a 
"worldwide" standard.  The code which follows, viz.

public final class ButtonCommand {
  private ButtonCommand() {
  }
  public final static String getCommand(HttpServletRequest request) {
Enumeration enum = request.getParameterNames();
String parameterName = null;
while(enum.hasMoreElements()) {
  parameterName = (String)enum.nextElement();
  if(parameterName.endsWith(".x")) {
return parameterName.substring(0,parameterName.indexOf('.'));
  }
}
return parameterName;
  }
}
simply does this using image tags instead of hidden parameters in the 
form.  You can, of course, just copy the method getCommand into your 
processing helper classes in the model.

Does this ring any bells?

The problem is that both solutions in a higher level

Re: Intermittent problem with DispatchAction

Thanks for that Kishore,

I was wondering how the request parameter gets set to null. Because, we
include the request parameter as a hidden property in the JSP, the
javascript method is always called with a hard coded string as argument
e.g.  html:submit onclick="setAction('applyChanges')" value="Apply Changes"
, and the parameter has a default value set in the form.

Just as a side note, we are using https. Could there be a problem with the
version of Internet Explorer we are running. I have seen from the mailing
list that there have been issues with IE 6 SP1 and SSL.

Thanks
Mike.

 "action", Your request parameter, which drives which method to
dispatch to, is null for that particular request.
Thanks,
Kishore Senji.
The reason the request parameter is null is probably because your hidden 
parameter is misspelled or something.  I am not sure why people like this 
DispatchAction.  It overcomplicates simple solutions and leads to this sort 
of problem.  In my opinion, using the DispatchAction just complicates and 
couples matters that don't need the complication and certainly don't need 
the decoupling.  If you had merely used, for example,  and not set your parameter in your action 
mapping to 'method', you would achieve the same result.  The only thing 
that DispatchAction and LookupDispatchAction do is to tie the parameter 
attribute value in the ActionMapping to a given parameter name in the 
request.  This is not a good thing, in my opinion, but a bad thing.

Struts security/validation

[James Adams]

Hello all,

I'm in the process of trying to secure my struts application against "Cross site 
scripting", "SQL injection" style attacks.

One of the things I'm doing to prevent this is trying to restrict special characters 
(;.<>(){}...etc) getting beyond the validator.

At the moment I'm using the validator plugin, within my validation.xml I use the 
"mask" validator with the regular expression;

.
mask

^[^;"'\.\^\$\*\+\?\{\}\[\]\\\|\(\)]+$

.



1. Does anyone know the syntax for also preventing < > & within the regular expression 
bearing in mind its declared in XML?

Or is there some kind of default validator that does this?



2. Some of my action functions also take input in the url as a GET which does not go 
through the Validator, this is then used to access a DB, these also need to be 
secured.  Obviously I can do this within each individual Action class, but where would 
be the best single place I could stop characters like < > ; &  ever getting as far as 
the Action classes?

Any other suggestions would be much appreciated, as I couldn't find very much related 
to securing struts applications  

many thanks in advance

regards

James

Don't get stuck on what the XML does.  Use those values as a tool rather 
than as a restriction or boundary.  You can redefine the ActionForward in 
your processing at any time.  The user can be sent back, given different 
validation problems to any page you want.

I get you. This is what we have currently, the problem is that when the 
validation ( on say page 5 ) fails the user gets sent back to page one 
because only one input page parameter is allowed per action definition 
(in struts-config).  It seems to me you still have to define a separate 
action path for each page you want validated (though it would map to a 
particular function in your DispatchAction ) .

Intermittent problem with DispatchAction

[Michael Searles]

 
Hi Folks,

I am using a DispatchAction which switches between several methods depending on the 
value of the forwarding parameter which is set in the JSP(see code snipet below).

The DispatchAction is fine approx 80% of the time, but ocassionally and without 
warning, I get the following DispatchAction error --
 ERROR [apache.struts.actions.DispatchAction] Request[/admin/UserDetails] does not 
contain handler parameter named action.

Its difficult to trace this problem because of its intermittent nature and 
unfortunatley i can't provide more detailed info at this time.

Any help wouuld be appreciated.
Mike.

I am using Internet Explorer 6 with Struts Version 1.1 


Code Snipet.

* javascrip fuction ***
function setAction(val) {
document.forms[0].action.value=val;
}
***

Re: Should every Action have an associated form?

Hey everyone!
I hope to not get flamed, but it's getting late here and I'm tired of 
looking through the archives.  Should every Action have an associated 
ActionForm?  Is it a bad idea to read a parameter directly from the 
request in the Action?  I have a page where I need to show details 
for a particular item in our database.  People will be directed to 
this page via a url http://127.0.0.1/foo/bar.do?id=123.  If I need an 
ActonForm, what's the best way to set this up in the 
struts-config.xml?  Thoughts?

Thanks in advance!
Matt

RE: I have a form spread over several pages. The user fills out each section in progression. I am using a dispatch action and each page calls the same function i.e. processForm. I want struts to validate each submission but I cannot change the input page

[Kataria, Satish]

I am suggesting that you should have a single action having a method for
each of the page. This can be configured by using DispatchAction class
and configured in struts-config.xml using the attribute "parameter" for
finding which of the method to execute.

Thanks,
Satish

I am interested in this too, but do not understand the suggestion. Are 
you saying that if you have a 10-page input process you should define 10

separate actions? Is there no way to dynamically change the input page 
in struts?

thanks

Hi, 
Instead of having a single function what I would suggest in ur case is a
session scoped action form
And each page having same actionform but different action mapping. Thus
using this you can specify approiate page as the input page.
For code examples refer to struts documentation of using action scopped
action form.
Please revert in case of any problems.

Re: using tiles with dynamic links

Competitions? I've seen C ones (the 12 days of Xmas one is a classic), but
truly idiomatic Perl is self-obfuscating!

Let's not get into language wars, eh?  I did Perl then, I do Java now, I
want to keep legacy content, but integrate it with the tiles-based
templating if possible.

Still, got a few ideas out of this thread, and I'm looking at scrape right
now.

Cheers
