Varying Performance for different windows users
Hi all, We have a J2EE application build using struts, EJB and oracle as database. This is behaving strange. When X user logs into windows machine and access the application, performance measures are different when user Y logs into the same windows machine. Could anyone please help me to solve this problem?

Performance
Hi all, I have a application developed through Struts. Application is behaving very strangely on performance side. Performance measures are different depending on the user who is logged in to the machine. Is there any relation between Windows User Profile and application performance? Regards, Viral

FW: Singleton pattern to business delegate
Any reply…?? -Original Message- From: Viral_Thakkar Sent: Tuesday, December 30, 2003 7:03 PM To: Struts Users Mailing List Subject: Singleton pattern to business delegate Hi, Below text I found from sun java forum. “The pattern catalog describes the business delegate as containing an instance of an EJBObject where as the service locator can optionally cache an EJBHome object. The former avoids repeated JNDI lookups and creating an EJB whilst the later just avoids repeated JNDI lookups. Using this strategy, the delegate looks up the home interface and creates an instance of an EJB on creation; it has a one-to-one relationship with it. We don’t really want the delegate to have to create an EJB from the home interface in every method so it should therefore contain an instance member. This all means the delegate can’t be a singleton; it can't share that EJBObject with multiple clients.” Is there any another pattern which is useful to apply to business delegate classes?

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

For each different type of exception situation, should we have different exception classes or just a set of classes solve the purpose? -Original Message- From: Navjot Singh [mailto:[EMAIL PROTECTED] Sent: Monday, September 01, 2003 6:23 PM To: Struts Users Mailing List Subject: RE: Exception framework Usage 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.

Hi, Please suggest the exception framework in a scenario in a following scenario. Struts Action class à Business Delegate --> EJB à OR Mapping (Top link) à 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. 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). 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. At struts layer, in the Action class’s execute(), we will catch all these business exceptions. Please provide your valuable inputs. Thanks in advance. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE : Remote and local EJB
I think this part we need to explore. Even I don't know about this configuration but if we can find solution to this then nothing like that... Otherwise configuration using the external properties/xml files always there... :) But still I think we need to have code for both , accessing remote and local EJBs in the EJB client program (business delegate) and it will read some file and will execute only one of the block (remote or local)...

Remote and local EJB
Is there any struts support or any one has idea on following problem? I am developing an application in which I require to develop an EJB with local and remote interface. Local or remote EJB should be invoked depending on the request. How one can identify this? Any framework which support this local and remote EJB development and access? -Original Message- From: Robert Leland [mailto:[EMAIL PROTECTED] Sent: Monday, August 18, 2003 9:39 AM To: [EMAIL PROTECTED] Subject: [Validator] The Validator Wiki needs you !

Should extend any struts components ?
While developing the J2EE application using struts, should I extend the ActionServlet, RequestProcessor etc... classes to make them my project specific? If yes, which components and what are the advantages one can get? -Original Message- From: Robert Leland [mailto:[EMAIL PROTECTED] Sent: Monday, August 18, 2003 9:39 AM To: [EMAIL PROTECTED] Subject: [Validator] The Validator Wiki needs you !

RE: Best place to hook the Security Call
Hi Max,
Thanks a lot for your reply.
Referring to the last para of your mail, should we still require the
single list of roles... I mean each role named "c1234.admin" for company
#1234 and role named "c5678.admin" for company #5678 ???
Thanks,
Viral

Subject: Re: Best place to hook the Security Call
One approach would be to use a proprietary programmatic security system.
You
would have to check for a (user,company,role) combination for requests
that
have security requirements. This may in fact be the best way to handle
your
requirements, given that the same HTTP requests (/editCompany.do) will
likely be used for many operations across different companies.
You could "flatten" the company/role space into a single list of roles
that
follow some convention. For instance, the "admin" role for the company
with
id=1234 could be mapped to the single role named "c1234.admin" or
something
like that. Then you could check to see if the current user has that role
when deciding if they should be able to perform some admin action for
company #1234. This approach can be used in conjunction with the
programmatic system I described in the first paragraph. An advantage is
that
you can use the standard isUserInRole() call to check for access, but
you
will still need some proprietary way to create the role name to check
for.
You could always have a utility class with some methods like this:
boolean isUserInRoleForCompany(HttpRequest request, String rolename,
Company
company) {
String role = generateCompanyRoleName(company, rolename);
return request.isUserInRole(role);
}
String generateCompanyRoleName(Company company, String rolename) {
return "c" + Integer.toString(company.getId()) + "." + rolename;
}
One potential downside to this flattening, however, is that you may end
up
with a huge number of roles. While this, in itself, may not be a big
deal,
some containers and realms do things like load every role a user has
into
memory as part of their Principal object. If a given user only has a
handful
of roles at a handful of companies, this may still not be a big issue.
But
it is something to watch out for as you decide on a solution.
If the large number of roles is a problem, you would have to write your
own
methods to do the checking. This isn't so bad from the Action
programmer's
standpoint, as they would be calling an application-specific method to
determine access anyway (like my isUserInRoleForCompany() example
above).
The downside is that you would have to do the db lookup yourself (as the
implementor of these methods), rather than being able to rely on the
isUserInRole() method and your realm implementation to do the lookup for
you.
People have asked about this kind of thing for SecurityFilter before.
Perhaps there is some opportunity to offer some kind of support, but
you'd
still have to plug-in a piece of code to dig the company id (or
equivalent
information) out of the request. SecurityFilter might allow you to map
URLs
to some implementation class that would generate a role name that it
would
check for, or perhaps, more flexibly, allow the class to decide if
access
should be granted or not directly. This is an interesting area to
explore,
but there are no plans for this support now, so it would be a while
before
this kind of thing makes it into SecurityFilter. I do like that it
separates
security from the implementation of the request handling code (Action,
JSP,
etc.), but it is unclear whether it would be worth the added complexity
to
me at this point. Your requirements do make this option attractive,
though,
and I know others have to do similar things. Any feedback in this area
is
welcome (perhaps on the SecurityFilter forum so we don't waste
struts-user
bandwidth: http://sourceforge.net/forum/forum.php?forum_id=200424).

Subject: RE: Best place to hook the Security Call
I have an authorization requirement as below.
1. A user can have a role for a specific company.
2. A user can have many roles for a specific company.
3. A user can have different roles specific to different companies.
It means a user can have few roles for Company (lets say ABC Inc.) and
can have few roles (same or different) for some other Company (lets say
XYZ Inc.)
User Access level changes for each request depending on the role and the
company (company, which exist at that point).
Please help in suggesting the authorization framework I can use for such
requirement.
Can SecurityFilter component help me in implementing this requirement?
If yes, how..??

RE: Direct ValueObject creation rather than ActionForm.
Yes, I agree that it is not good programming to replace the ActionForm with ValueObject. But let me know your view about having both ActionForm and ValueObject and use some kind of mapping to get the ValueObject instance from the ActionForm instance. Example is available at http://www.mycgiserver.com/~andrej/technical/struts/struts.jsp Here usage of vo = FormToVOMapper.map(form, new ExampleVO()); is shown. Please suggest me whether this is good to use such mapping to get the valueobject instance and also do they support all possible datatypes and different mappings.

RE: Direct ValueObject creation rather than ActionForm.
Yes, I agree that it is not good programming to replace the ActionForm with ValueObject. But let me know your view about having both ActionForm and ValueObject and use some kind of mapping to get the ValueObject instance from the ActionForm instance. Example is available at http://www.mycgiserver.com/~andrej/technical/struts/struts.jsp Here usage of vo = FormToVOMapper.map(form, new ExampleVO()); is shown. Please suggest me whether this is good to use such mapping to get the valueobject instance and also do they support all possible datatypes and different mappings.

One drawback. ActionForm classes import classes from http packages. which binds it to the particular layer.

RE: Direct ValueObject creation rather than ActionForm.
Please let me know the consequences of the approach I mentioned. Thanks. -Original Message- From: Andrew Hill [mailto:[EMAIL PROTECTED] Sent: Friday, August 01, 2003 10:47 AM To: Struts Users Mailing List Subject: RE: Direct ValueObject creation rather than ActionForm. This is quite a common idea that many people new to struts have. There are quite a few reasons why your ActionForm and your value object are different objects. (Indeed the very reason ActionForm is implemented as a class rather than an interface is specifically to discourage people from using their ActionForm as a value object.) If you search the list archives you will see numerous threads discussing the reasons why this is in fact a very bad idea indeed. -Original Message- From: Viral_Thakkar [mailto:[EMAIL PROTECTED] Sent: Friday, 1 August 2003 13:05 To: [EMAIL PROTECTED] Subject: Direct ValueObject creation rather than ActionForm. I have a idea here. Why we require ActionForm class if we can have ValueObject and that we can pass to the service layer. Can we create the instance of ValueObject class only rather than ActionForm instance from the request data?

Direct ValueObject creation rather than ActionForm.
I have a idea here. Why we require ActionForm class if we can have ValueObject and that we can pass to the service layer. Can we create the instance of ValueObject class only rather than ActionForm instance from the request data?

Distributed components placing
In a typical distributed web application using the struts framework. The flow designed is as below : StrutsController --> ActionForm --> Action --> Business Delegate (Uses Service Locator) --> Session Facade. Details : The query is whether Business delegate component should be part of client jar file or it should be part of server jar file? I think, business delegate and service locator will be part of client jar file as business delegate is used inside the Struts Action class execute() method. And service locator will be used by busiess delegate to get the session facade. If service locator component is required at session facade also then should we keep service locator component in server jar also? Thanks in advance. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
