RE: [OT] JSP or Velocity

[Navjot Singh]

hi,

As far as i am concerned. My prefs are Eclipse and UEdit(designers can use
in combination with other design ides like dreamweaver etc).

RE: [OT] JSP or Velocity

[Navjot Singh]

Basically, i use velocity only for email templates and sometimes to generate
other kind of templates from one template where the use of XSLT is not
appropriate.
For web templates, that have more complex requirements, i prefer to use
taglibs. besides el makes life as easy as we may talk in velocity. In
velocity, to comprehend taglibs, you may have have to write lots of
velocimacro.

you may ask for another opinion on velocity-user list as well.

RE: Status 500

[Navjot Singh]

that's exactly what i am saying.
Form bean is created. so far so good. the constructor is there to be
accessible.
Now, it's turn to populate form and there we have a problem. That leads to a
thought that
One the members or it's corresponding method seems to have problem

it would be great help if you could post your Form and request params here.

RE: Session management

[Navjot Singh]

struts has nothing to do with managing sessions. we should better 
talk about servlet containers that handles sessions.

btw, 100 sessions are nothing to worry about :-)

leave the txn mgmt to db layer. use any of the persistence frameworks
that can handles this for you.

yes, you are right that MVC is a pattern, rather architectural pattern.

RE: urgent please -- XML document reading/parsing through SAX for the given snippet.

[Navjot Singh]

create a hashmap object and while you run SAX thru your xml document.

is yourStartElement(), save the tag name currentElement variable.
in characters(), save the characters value to your hash with key as
currentElement.

in the end, your element will filled.
if you multiple such case tags. add them into vector one by one.

but why don't you use digester to traverse your document? any reasons.

RE: Role based access?

[Navjot Singh]

in this case, Form is decalratively saying that it can be accessed only by
"userRole".
Now when you use CMA, every user will be bound to to a role.

RequestController compare the two roles one from user-in-request and other
from
ActionMapping/ActionConfig and continue..

However, you can also override the default behaviour of processRoles and go
your own way.

RE: trubble with session

[Navjot Singh]

When the user doesn't accept cookies, session is of no use.
After login, you can fill the data in request object and *forward* the
request.

look into RequestDispatcher.forward()

RE: [OT] Case insensitive Map keys

[Navjot Singh]

hi,

seems like you are ready to go down to bits. my 2 cents for you to try

==> convert string to array of bytes.

1. AND every byte with 1101. all will give you same output.
OR
2. shift left the every byte by 3 bits.

keep pushing the resulting byte to another array.
create string again of those bytes.

Saves you 2 relations operator, one condiiton checking, one
subtraction-assign. object creation is same. you create Integer. I create
String.

please let us know if you gain some performance.

RE: Hi

[Navjot Singh]

i could have given you my test case if i had not thrown away earlier.
but you ca write a test case that create 10 threads and open up 100
connections. don's close.

if your max-pool-size was set to 500 and pool can expand. then in the end,
the total open connections returned from the pool should be 1000.

then just changes the test case to close connections. now in the end <=500
conns should be there.

May be other people know of some tool to do that? i know JMeter but i have
not used that.

2. configure the data source in struts

Rather than performace issue, it's more of teams-developing-on-diff-modules
and project-maintainance issue.

you know jsp:forward tag. the url in that tag needs to have module name and

yes, see module switching in docs.

well in that case, if you map is not modified frequently, try the

either you override and read and write your own.

RE: [OT] Case insensitive Map keys

[Navjot Singh]

yes. here it is.

public CIMap extends HashMap
{

public Object get(String key)
{
return super.get(key.toLowerCase());
}

public Object put(String key, Object value)
{
super.put(key.toLowerCase(),value);
}
}

This was simple implementation. By the time you ask the Q and wait for
reply. you could have written on your own.

RE: forwarding all request to the one JSP

[Navjot Singh]

jsp is servlet but servlet is not jsp. hope this point clears the point
here.
you should look into using jsp error page directive if you wish to redirect
errors from jsp page.

RE: [OT] - Request against Session

[Navjot Singh]

first some clear thoughts.
1. In html everything is string. it doesn't understand anything else.
2. Session is created the first time the user has sent in a request unless
you have overridden this behavior.
3. If user disables cookies (rare case now a days), storing objects in
session is futile exercise.

Use of session or request varies on requirements basis.

1. Start with first form, collect values, pass as hidden values to second
form and so on
2. Start with first form, collect values, save to session and so on

RE: 2 PROBLEMs-Please Help

[Navjot Singh]

1. did you check the same property name in your messages.properties file.
2. ActionMapping is not deprecated. Reads the docs again. It saya "would
have been deprecated". in fact, this class has 2 more subclasses.

RE: problems w/ logging.. again

[Navjot Singh]

if you are using jdk 1.4 then why don't you switch over to JDK logging? No
configuration issues here as you might face with log4j.

Well it's just a suggestion, as i myself use JDK logging in some projects
and log4j in some.

btw, in struts 1.1, i don't think debug param plays any role.

RE: Querystring builder

[Navjot Singh]

hi,

Yes, i was referring to copyProperties().

The problem really gets complex if you have nested objects.
and i doubt if there is any readymade solution to the problem you are
facing. but with very little effrots you can do this

You can make one and for all. Doesn't seem to be a tough job althought bit
lengthy :-)

Ok, allow me to get my hands dirty!! and I am not sure if this works with
collections as you may want. You ca try with collections yourself.

Say you have something like

class A (with corresponding gettter and setter)
{
private B b;
private String str;
}

class B (with corresponding gettter and setter)
{
private String str;
}

All you need to do is

A a = new A();
a.setStr("navjot");
B b = new B();
b.setStr("singh");
a.setB(b);

Map m = new HashMap();
Then call BEanUtils.copyProperties(m,a);

you will get a map filled with key-value pairs
str=navjot
b.str=singh

pass this to some function like.

String getQueryStirng(Map m)
{
Iterator nvPairs = m.keySet().iterator();
StringBuffer nvString = new StringBuffer("");
String key;
while(nvPairs.hasNext())
{
key = (String) nvPairs.next();
nvString.append(key + "=");
nvString.append(this.getString(key) + "&");
}
String nv = nvString.toString();
if(m.keySet().size() != 0)
{
return nv.substring(0,nv.lastIndexOf("&"));
}
return nv;
}

My this function may not be efficient and does the job you want.

and HURRAY!! you will get QueryString like
str=navjot&b.str=singh

hope this helps
Navjot Singh

RE: Querystring builder

[Navjot Singh]

that should be easy.

BeanUtils gives you the way to populate a MAP object from a Bean.
Now al you need to do is iterate over keys,
form a querystring with each name-value pair separated by &.

RE: PDF file in browser

[Navjot Singh]

if you can reveal the location of the PDFs on your web server.
Simply put your pdfs under a www/app.com/pdfs/*.pdf and give them links as
you want.

if you wish to maintain some security.
1. send a request to a servlet wit some pdf code or file name
2. open the given file from the file system whereever it is.
3. convert it into stream.
4. push the stream back to browser.

note - must set the appropraite mime/type before you push the stream back.
may be application/pdf or application/x-pdf

RE: When HashMap will replace ActionForm ?

[Navjot Singh]

I can't say there will be any move or not.

But MAP backed ActionForms are alreadt there, If you are not interested in
using the actionforms and be contended with just hashmaps. Mostly, not
always, I treat ActionForm as HashMap but with getter setter already
classcasted and defined for properties. not more than that.

RE: Error message display in the case of redirect = true

[Navjot Singh]

not sure but the logic says that error messages are being stored in the
REQUEST SCOPE and when you set redirect=true, naturally that's a new request
so you won't get the errors set in earlier request.

anybody else?

RE: Struts and commons DBCP

[Navjot Singh]

tomcat 3? guess that was a stone age :-)

My second question is : do i have to close the connection when may request
is finished ? Does this really close the connection or just free the object
i used, but save the oracle connection open ?

Yes, please close the connection. Actually, this method gets trapped by
PooledConnection interface and the connection will be returned back to the
db pool and it WONT get closed.

RE: Changing SessionId at every request

[Navjot Singh]

don't know why do you wish to do so?
but it an be done. Write a filter. pass every request thru that.

1. Fetch the session, expire it. Server will assign new.
2. Fetch the session, don't expire the session, just append a timestamp to
it. set a cookie and use that to maintain session.

surely in ActionB. Filling it's own form is action in itself.

you can parameterized your action to do 2 things

2. accepts the submitted formB.

That's one of the skills that business look for. Same work for less money.
Slowly, when all your US companies outsource their work to eastern countries
like india/china, you will have no other option but to go to those countries
OR just fight till death in your country.

BTW, When you get OIL you are all OK, when you PEOPLE it HURTS.

The biggest fact is that Americans are starving fellow Amercians out of
jobs.
Not Indians.

Anyway, this year, just one third of H1B will be issued in India for US as
against the past years for the interest of better employment to native
amercians.
See if this can help your job ;-)

I have never been on H1B for your info and don't even want to be. However,
if you are interested to work in india, send me your CV.

Business look for skills. If Americans could provide ample, your businessmen
WONT search in other countries. AND not every indian get a job over there.
Indians who are better than guys like you get there. One day you or your

RE: Forward/redirect and virtual hosts

[Navjot Singh]

you said it's apache problem but you never mentioned apache's role in
problem. So, i will assume you are using mod_jk to have apache tomcat combo.

First thing to check is httpd.conf . Is your webapp and mod_jk handler are
listed under your *external* host name.
Second thing to check is server.xml. Is your webapp context is configured
under your *external* hostname?

I can think that one of this is broken and hence the problem is coming. Or
if we can get config files, i may help better.

RE: urlrewriting Vs Cookies

[Navjot Singh]

here is the clue.

cookies are again of two types.

+ persistent - will remain there even if you close browser and opens next
day.
+ non-persistent/session - the moment you close browser window they are
gone. These also work only under child browser windows.

So, i assume you are looking for session cookies.

If you love URL rewriting, you can disable the user session after 10 minutes
of inactivity. Depends on how much pain would you like to take for it and
how secure you wish your application to be.

if you are adamant about not using cookies at any level. URL rewriting is

RE: Container-Managed Authentication in web.xml vs . Specifying Paths in the struts-config.xml

[Navjot Singh]

you may wish to look upon JAAS if you have so many diff roles and user per
roles.

Anyway, struts lets you specify role atrribute (that takes comma sep values,
i guess)
for each action. If you can extend RequestProcess class and modify the
processRoles() method so you can redirect to any page if the roles are not
valid for that action. etc etc..

Struts,using decalrative roles, tried to make things easier in term sof less
programming efforts and easiness to manage roles . Rest i can't see much
diff. Any opinions?

RE: Performance constraints

I have hardly noticed nay perf loss on using struts. Naturally, every
framework has some overheads but you got to trade off with the maintence and
scalablity perspective and patternized arch.

>--> How does the action servlet take care of multiple requests for
>the same web application ?

There will be only 1 ActionServlet instance. Any request that's coming to
webserver will be forwarded to ActionServlet. ActionServlet tries to assign
one Action instance from the pool. If it's not there, the new Action
instance will be created and assigned to the request.

RE: Exception framework Usage

[Navjot Singh]

Well, that's a very nice question.

I have created 1 jar file that's called commons-exceptions.jar (I like
apache commons a lot :-)
Then it depends upon your packaging how do you wish to go about it. I
generally keep this in my app.war.

>Please provide your input on the directory structure.(at web
>layer and also at application layer) or exception classes
>should be at root level?

Keep any directory structure that you wish. As an example, these base
exceptions can be in com/navjot/exceptions.

then you can have
+ web specific exceptions in /com/navjot/web/member/exceptions/
+ ejb specific exceptions in /com/navjot/ejb/member/exceptions/
>Also let me know whether your base exception classes (AppException
>and AppRuntimeException) extend from Exception or
>EJBException or something else?

My AppException extends from Exception and AppRuntimeException extends from
RuntimeException.

>For each different type of exception situation, should
>we have different exception classes or just a set of classes
>solve the purpose?

Ideally, exceptions are bound to some flaw in business logic. So should be
kept together.

However, if you wish, you may replace
DuplicateEmailException & DuplicateUserException
with

DuplicateKeyException
- what   /*what is duplicate, email oruser*/
+ getWhat():String
+ setWhat(Stirng)

It's just another way that is desired sometimes. Personally, I never
followed this staregy ;-)

hi viral,

You are thinking in the right direction. That's the way i do it.

I have got 2 base exception classes. AppException and AppRuntimeException.

1. The exceptions that come under the purview of the business logic and
these can be handled somehow at the controller/model layer to alter the flow
of control MUST extend AppException.

2. The exceptions that does not come under the purview of the business logic
and raise because of the system or network problems MUST extend
AppRuntimeException.

However, one must use some common sense to decide which exception should go
where.
Say, we are connecting to some URL and it may throw TimeoutException. which
is not a checked exception. We must be ready to capture this and throw some
checked exception.
The caller may catch the exception and try connecting againmay be thrice
;-) and if still no luck the caller passes on the message to PRESENTATION.

So your code will not be cluttered with "throws XRuntimeException" and
tthese exceptions MUST be handled back at CONTROLLER layer only. MODEL layer
should just handle CHECKED exceptions.

Examples
At Controller  => DuplicateEmailException extends AppException (we may
display the same form showing error on top)
At Model => InsufficientBalanceException extends AppException (we may charge
as much as he has got and rest of the amount we will accomodtae in next
invoice)

DatabaseAccessException extends AppRuntimeException ( as there is hardly
anything we can do about this. We MAY show some nice "SORRY" page and/or may
LOG this exception somewhere)

BTW, there is some nice article on "Exception handling" on IBM Developer
site. Do check.

hope this helps and suggestions are welcome.

  Hi,



  Please suggest the exception framework in a scenario in a following
scenario.



  Struts Action class  a Business Delegate --> EJB a OR Mapping (Top link) a
Domain classes



  Please validate the below lines.



  There will be three layers at which we need to handle the exception.



  At EJB layer, at business delegate and at struts layer.



1.. EJB layer (session bean) methods will throw the (Application)
business exceptions along with RemoteException. In the catch block it will
throw the EJBException (in case of checked system exceptions like
NamingException).
2.. At business delegate layer, we will throw the application exceptions
in the catch block rather than EJBException to decouple the web layer and
EJB layer.
3.. At struts layer, in the Action class's execute(), we will catch all
these business exceptions.


  Please provide your valuable inputs.



  Thanks in advance.

|Well, possibly not an elegant answer but...
|
|1) Under *nix we've done this with "cron" and a "bash script" that invokes

|2) Under Windows we've used a VBS script via "at"/"winat"/"Scheduled Tasks"

|
|Both have been very reliable (in fact both are in very widespread use on

RE: Design question

|Now my questions are :
|1> I am doing write something wrong.

It's better not to club two logically different business process handlers.
I guess you want to reduce the number of Action Classes to be created. If
yes, follow this way




In your action class..

String doWhat = mapping.getParameter();

if("proj".equals(doWhat))
proj.create(dto);
else if("user".equals(doWhat))
user.create(dto);


|2> Validation errors are to be send to called jsp. Like validation
|error for create user has to be send to create user jsp, for that
|i need to dynamically change the value of input in my action
|mapping, how to do this.
|3> Since the form beans are different for each jsp can i
|dynamically change the formbean of the actionmapping
|4> can you suggest some alternate method so that i can not have to
|do copy past of my code in execute method of action class.

If you follow my advice on 1, you need not to bother about that.

RE: Design question...

[Navjot Singh]

hi,

If are getting some collection to the JSP page and just wish to display a
subset of them without changing anything on BL layer, Use Pager Taglib and
get away with it easily.

But there is a downside to it as you may have 1000 records and you just want
to show 10. So, 990 records are burden on network for no use at all.

But you can avoid this also. Pager taglib provides you with one parameter
"offset" that can be passed onto the controller layer and then to your
Session EJB. Session EJB will trim the 1000 records collection obtained to
10 records based on that offset value. Now when you pass the DTO back, it
will contain maximum 10 records. Reducing network load and you get only
those records that you want in presentation layer.

RE: login request + ActionServlet RequestProcessor Action

[Navjot Singh]

Although I am extending Action class as of now but
extending Requestprocessor should be a better choice. After all
ActionServlet, after all the initializations, delegates control to
RequestProcessor.

Let's keep ActionServlet only for one time inits.

RE: Security and Roles related

[Navjot Singh]

hi sree,

I suppose all you wish to do is to control flow/display based on different
roles.

If yes and you have struts 1.1, pls read on.

Struts allows you to set roles for different actions using
strust-config.xml. So, user belonging to particular role say "ADMIN" can
call that ACTION.

Moreover, in your JSPs, you can always check isUserInRole() etc. it's just
call on your request object.
Struts even provide the tag for that  et al..

do write should you need more help.

If you are using servlet 2.3 container, write a filter that can check the

if your servlet is extending ActionServlet, you can retreive the DataSource
from
ServletContext.getAttribute(Globals.DATA_SOURCE_KEY). You may have to append
"module key" to DATA_SOURCE_KE if you are using  modules.

If your servlet is NOT extending ActionServlet, better move( or copy?) your

RE: Development time using Struts,

[Navjot Singh]

I agree with puneet saying that struts does saves a lot of time in
development of large apps. After all, frameworks are meant to provide a set
of services and also defines the boundaries of the system in which the app
developer should put his/her efforts in.

Even with frameworks around, developers need to have standard practice of
coding so as to keep the code flows almost same for the entire app. With
that in place, it's merely copy and paste for the routine jobs and you get
more time to focus on the actual business logic. However, good IDEs also
save lot of time.

So, if you know a framework that suits your needs, it WILL save lots of
time.

regards
Navjot Singh

|Hi to all,  I want to raise a question here about development time
|using Struts,
|
|I am using Struts about 4-months now,
|I found it a very good framework for developing web-applications,
|but the devolpment time in contrary with the  classicc way(jsp, serlvet)
|is much more using Struts.
|
|Also i find it useless when you use ejb in your applications, you
|have to make  "MANY" iteration to pass parameters & results from
|front-end to back-end and vice-versa, which of cource costs to
|much in performance.
|
|
|I would like to hear other struts-developers for their experience.

RE: need suggestion on logic

[Navjot Singh]

very simple. say user fills in text field and press enter.

1. Pass the control to an action "Checker".
2. Checker will verify if the process needs login.
3. If NOT, case is clear.
4. If YES,
   + Store the request state variables in some object.
   + Save that object in Session.
   + Pass Control to "Ask Password" page.
   + "Passwd Manager" checks if pass is OK?
  + If NOT re-display the "Ask Password".
  + If YES,
- save pass state for Checker's sake.
- retrieve the request state variables.
- Dispatch a request to checker again.
  This case will be treated same as 2,3 steps.

Checker can be implemented either using
+ Filter OR
+ Some method in Base Action
+ extend request controller.

See what suits you.
-Navjot Singh

PS - If all you are looking for is general login system. See CMA/Realm
Security.

| Hi,
| I am building a web application using struts1.1, and
| this is my requirement,
| There is a jsp where in user will enter data in text
| field, and then press enter, this will submit to a
| Action class, this action class must decide wether a
| relogin page has to be displayed or not, and if yes
| then display a relogin page, the user will enter the
| password, if the password is correct, perform the
| task  of entering data in database, if the password
|is
| wrong  or user presses cancel, then take him back to
|   the jsp from where the user came, and populate all
|the data which was entered in jsp,
| If there is no need for relogin screen, enter the
| data to  database.
| the puzzle here is how do i write that common Action
| class which will handle to display the login page,
| and
| other Action class which will validate the password,
| and forward the request to other class
| So i need to remmember where the request came from
| and
| where it has to go??
| need help on this
