Question about Struts and XSL

[John Owen]

I inherited an application that uses a Model-1 MVC approach. I was hoping to 
migrate the application to the Model-2 approach that Struts offers. My 
problem is that a particular jsp page uses xsl to render a form and its 
elements. This particular page is the heart of a module that performs 
several tasks and I am unsure of how to proceed. My concern is that I will 
have to completely re-design the jsp/xsl combo to remove the form elements 
from the xsl in order to use the Struts html taglib and Action/Form classes. 
I was hoping to move code that resides in the jsp page into an Action class.

I looked through the message archive here briefly and found a few posts 
about stxx (I think), but I'm not sure it would help without a re-design. 
Any ideas or alternate approaches would be greatly appreciated.

Thanks,
John

Re: Struts Vs. Sun J2EE Compliance and Design Patterns

[Eddie Bush]

I appreciate all suggestions ;-)  I'll start off with the book I 
mentioned and proceed from there as I feel the need.  I love to learn 
about "processes" though - they are what enable us to do what we do 
easier/faster/better.  I especially like to hear comments like "Oh - 
that was a super read.  It presented enough material I could apply the 
concepts right away!"  I think the end goal in reading any book (of a 
technical nature) is to improve your abilities by doing so.  I know I 
have room for improvement :-)  UML/UP is one (really quite large) thing 
that I think would help me out tons.

Thanks :-)

Yes, struts is super when it comes to flexibility :-)  Personally, 
having the view that each developer is responsible for the quaity and 
correctness of whatever he turns out, I don't mind JSPs for 
presentation.  I mean - I know what good and bad is - I choose good. 
 It's kind of like when I was in college and one of my peers said 
something about arrays in C not having bounds-checking.  This came up 
because there was a BOOK teaching people that ARRAYS IN C START AT 1!  LOL

What it comes down to is knowing your tools, knowing how to use them to 
the best of your ability, and being willing not to compromise on things 
that "really matter".  Scriplets in JSP, IMHO, really matter - they 
don't belong there.  I'd rather have JSPs than have the overhead of 
having to dynamically translate XML into something else for each request 
(that _is_ how it works, right?)  Just use them "correctly" and there's 
no issue :-)  This is why organizations have policy - to enforce things 
like this.  Make a policy :-)

Peace,

Eddie

Re: SSL+Tiles

[Eddie Bush]

I'm not finding it :-/

You should be able to take the principals Ditlinger gives and transfer 
those concepts to 1.1 idealogies.  In other words, you probably want to 
extend RequestProcessor instead of ActionServlet.  I would think, with 
the advent of servlet specification 2.3, you may also find a more 
"container-centric" solution using a filter mechanism.

Enjoy,

Conversion from templates (Struts 1.0.2) to Tiles

[Tim T. Young]

I am converting a couple of test pages from templates in Struts 1.0.2 to
use Tiles.  My question is, how do I do something like this:

 
  
 
 
 



 


Can I use "extends" to turn the "sidebar" off?  From a couple of quick
tests this seems not to work (it tries to load a file called "" and
understandably fails)  The template stuff in Struts 1.0.2 was forgiving
enough to treat "" as nothing and would just return null or empty string or
something from the tag, not an error or anything.

Any info would be appreciated...

Re: Struts Vs. Sun J2EE Compliance and Design Patterns

Though some times this approach can back fire on you.

Some companies would rather shot them selves is the foot then do something
a person in management does not want to do (IF you did not ask first).  I
found that instead of trying to
make the person hang themselves it is easier to make it look like you are
following
their rules, and that is why you went with struts.

Token Functionality

[Kesava Achanala]

Hi All,
I just got one question on Token Functionality.
I written the saveToken and isTokenValid and
resetToken. They are working fine for reloading and
multiple submits. I have only one problem here when user using back button 
and modified the form and submit it again. even though the  request got 
changed but it is still going into the (!isTokenValid(request)) and showing 
the error message. Here what I am doing...

if(!isTokenValid(request))
{
  errors.add(",...");
}
resetToken(request);

if(!errors.empty())
{
  saveErrors();
  saveToken(request);

}

Is there anyway we can avoid this... Thanks in advance...

java.lang.LinkageError: loader constraints violated... org/apache/commons/logging/Log...

[Colin Wilson-Salt]

I'm getting a lot of these when I redeploy applications (on JBoss 3.0 with
Tomcat 4.0.3, Struts 1.1 beta):

java.lang.LinkageError: loader constraints violated when linking

sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstruc
torAccessorImpl.java:27)
at java.lang.reflect.Constructor.newInstance(Constructor.java:274)

I can prevent it by blowing away the work directory under jboss' catalina
directory, so I'm guessing it's got something to do with classes being
loaded by different classloaders.

Is there anything I can do to avoid this? I've made all my Log variables
transient in classes that can be serialized (which is just about everything
except for my Actions), but I don't think that's my problem.

Any ideas?

Let's assume that you have the "foo" forward defined as something like:

  
  

and you use an  tag as above.  What does the generated HTML
look like?  Assuming the context path is "/myapp" it looks like:

  

which goes *directly* to the JSP page, not through the controller servlet.
The Struts tags on this page will not understand that they are part of the
"/bar" sub-application, because the controller never had a chance to set
the right request attributes.

This is the key step, isn't it?  What happens when a requst does *not*
come in to the controller servlet?

The answer is that the request attribute set by step 3) (I guess step 2 is
so magical nobody knows what it is :-) never gets set -- and Struts
consistently assumes that this means you are running in the default
sub-app.

RE: Struts Vs. Sun J2EE Compliance and Design Patterns

[Andrew Hill]

Hehe. I only learned enough to parse in my XHTML (which is just html with a
few / in the right places) and get a DOM (which is basically a glorified
tree with several types of nodes, and 90% of the time im just interested in
the element node type)). So if my xhtml has  I could use something like
document.getElementById("bob").setAttribute("value","yada yada yada");
(Actually I do a lot more and at an abstract level - but its still not very
technically complicated - the complexity is all stuff Ive added. For
example, if the bob element was a  or a  or a  etc... my
code is smart enough to figure it out and modify the DOM in an appropriate
manner, so I can fool around with the layout to a certain degree with no
code changes required).

Still havent learnt all that xPath, and xslt stuff... now THAT looks hard

Yes, it really is :-)  I'm in your reverse position though.  I found it
much easier to pick up JSP than XML.  To this day, I have an XML

Love the concept - hate the XML ;-)  No offense.  As I said, I have an

power.  I just haven't had time to put forth brain-power actually trying
to learn it well yet :-/ ... but I'm sure that day will come.

LOL - It's actually kind of all "declarative" in a way.  Have you read 
the stuff Chuck wrote on this topic?  That's where I got my footing at 
:-)  Go dig into Chapter 11 (I think it's 11) of Chuck's book and 
_really_ dig into it - and then let us know if you have problems ;-)

I'm just making use of what Dave has in validation-rules.xml and have 
pruned (ok, massacred!) validation.xml down to just what I wanted. 
 Initially, I just started (after reading Chuck's chapter) coding in a 
super-simple form from the dyna-forms examples.  Once I was satisfied I 
understood that (nope - never used them before - always coded them - no 
more!), I then changed it to a dyna validator form - with absolutely no 
validation associated with it.  Then, I incrementally built it - adding 
"depends='required'" to everything that needed it, adding masks for 
things that needed them.  I had seen several people were having issues 
with how Dave had done the JS, and so I didn't want to over-load myself.

 All in all, the form validation rules remind me of ant tasks 
sorta-kinda.  I guess the only similarity is really the depends= 
attribute ... but I always tend to think "ant" when I look at that file.

 The concept is the same - well kind of.

David builds up constructors for each requirement (in JavaScript that 
is) that is placed upon a given field.  For instance, all "required" 
fields are grouped together into a "required()" constructor.  This 
constructor builds up a collection of objects that he then iterates 
over.  Since each of the items in the collection has it's own validation

rules, he just iterates over the collection and validates as he goes. 
 He then does the same thing with masks (in my case).  It's pretty neat,

really :-)  Having written enough JavaScript to be "semi-comfortable" 
with what the output from Validator really helped me understand what was

going on.  It's amazing what you get when you "View Source" on a page 
with a form controlled by the Validator.  Ok - maybe not amazing - but 
it sure is neat :-)

If you have any specific questions/issues, I'd be glad to try to answer 
them.  I highly recommend Chuck's chapter on it though.

Regards,

Eddie

struts submitting form when validating javascript

[Brian Steele]

Hi all,

Thanks in advance for any help.

Has anyone encountered an instance in which struts 1.0.2 submits a form without a 
submit button or a javascript call to submit()?

I'm using javascript to validate my form.  This is an extensive library of validation 
functions i've built up over many years and is fully tested, reliable, etc.  In short, 
i recurse through the javascript DOM to find any fields that require validation.  If 
the required fields pass the validation, I call "document.forms[ xx].submit()" 
otherwise an error message is displayed via an alert popup and no call to submit is 
made.

Somehow Struts is submitting the form anyway, even when I have no submit button or js 
call to submit ANYWHERE on the page.  The server logs show that struts starts 
processing the post after the javascript finishes (and no submit is called).

I'm running this on JRun 3.1

Here's the relevant code:


...
...
...
  3 is the dom order of the form (4th form on page)

Sending response to browser as a ZIP

[Jan Fetyko]

Hi all,

I'm looking for some advice or solution that'd help me send the response 
to the browser as a zip file. I did found a tag that does it on :

http://www.servletsuite.com/servlets/opttags.htm

but I'm getting some errors while the page is rendered ( see bellow ), 
so I'm looking for a different way to do it. Does anybody know how to ?

My config is :
Tomcat 4.1.7 Beta
Java 1.4.0_01-b03
Struts

The error:

2002-07-26 06:46:45 StandardWrapperValve[action]: Servlet.service() for

Re: Login Question

[@Basebeans.com]

Subject: Re: Login Question
From: Vic C <[EMAIL PROTECTED]>
 ===
Now that you buttered me up:

basicPortal does not handle it, it just uses JAAS and Web.xml relms so 
it just illustrates how to do this.
(just like it illustrates how to do tiles action or how to use JSTL tags 
with Struts, how to store xml in DB and use Standard X:transform tag, 
several good practices that I teach implementation from)

In basicPortal users can see the first page without login in (list of 
content tiles) but if they want to see issues, submit content, add 
comments, add an issue, etc. they are forced to login.
If they have the right "relm" they can approve content.

So "relms" do not work without login, but once they are logged in, 
different groups can see different things (and auto passes parms, 
forwards, etc.) And of course you can leave some pages unprotected, 
and allow person to login in before going to the protected areas.

Like theServerSide.com:
You can see discussion topics "free". But if you want to comment or add 
content, you have to authethicate; except I did it in web.xml.
And a 3rd level might be, if users is in a "paid" relm, they might get a 
different layout and a different css, etc.


Vic

(if you are on a Struts project, consider using 
basicPortal.sourceforge.net for issue tracking at least - 800 downloads 
in 2 days;
I will write a few more verticals for it; is't it time that Open Source 
started doing verticals? - I will so smoke JetSpeed.
and ... mvc-programmers on group.yahoo, you can keep track play by play, 
or don't stand on the side lines; I welcome contributors)

RE: First Web Application: Really Need Help

[Singh, Sandeep]

Probably if you are going to use IBM tools
you can get a quote from IBM itself for all these things.
Even Websphere App server standard edition will
serve the purpose.You can use your existing Database(DB2UDB or Oracle etc)
where you business data is residing.

Hi to all,

I need really an urgent help. I have been given opportunities to build my 
first web application. It is a very simple application. It is basically a 
kind of time tracking application. Using this application a employee can 
enter the information for pay period (like any vacation sick, jury
duty.) 
and submit this for supervisor review. Supervisor is going to review and 
approve it. Once supervisor approved the information for a employee then 
employee can not change anything for a pay period. Finally few report based 
on the information. There would be around 1000 users who are going to use it

probably on Friday only.


I am sun certified Java programmer. i have been working in application 
development since last 6 years. I never build any web application. I need 
help to figure out some basic things. Please advise me ASAP.

Q#1
What is the best hardware for me keeping in mind that 1000 user is going to 
use it probably on Friday only?

Q#2
Do I need separate hardware for database or I can use same machine?

Q#3
Which server is best for me (like weblogic , websphere, )? What is the

Q#4

Resin 2.1.3 and struts: Problem

[Will Jaynes]

FYI. The latest Resin 2.1.3 does not work with Struts. It has a bug that 
prevents the ActionServlet from locating the web.xml and 
struts-config.xml files. So don't bother to upgrade until 2.1.4 comes out.

Some might use it on Monday mornings. That's what happens around here. Also, some of 
our folks enter their time at the end of each day. Will your system allow for that? My 
gut feel for hardware would be for a smallish Unix server or a medium sized Windows 
server. At least two CPUs.


>Q#2
>Do I need separate hardware for database or I can use same machine?

Need - no. Might be useful - yes. Design the system in layers and you can put the DB 
anywhere you want.

Your company most likely has a STANDARD that you should follow for fear that the sky 
will fall and cats and dogs will start sleeping together. If you like your job, follow 
the STANDARD. Me  I'm quite happy hacking around with JBoss.

>Q#4
>Which database?

See my previous comment about STANDARDS from upon high. We use DB2 here because our 
STANDARDS say so. I quite like HSQLDB for my own tinkering.

>Q#5
>Is Struts helpful for this kind of small project?

Yes and no. Struts is VERY helpful if you are building an MVC web frontend. Struts 
will not help or hinder anything that you do on the back end. On my current project, 
struts stuff is about one third of the whole project (100% of what the users see), 
while our back end is the other two thirds. We have found struts very helpful for the 
"V" and "C" in MVC, but remember that the "M" is huge! :-)

>Q#7
>Does websphere  work well with struts?

Don't know. I try to avoid W.A.S. as much as possible. See my previous comment about 
JBoss. Our tactically approved App Server for internal apps at this time is JRun. It 
works and no one swears at it.

>Any advice you guys think would be helpful for me are most welcome.

A web application is like an iceberg, the pretty bits are only the top 10%. Get an 
experienced web developer on your team. Contract in a mentor. This has worked well for 
a number of teams that I have been on.

Yes simply subclass it and add your custom validate() and reset() methods.
Make sure you have dynamic="true" when you define the form bean in

Q#1 - how many transactions each over how long?  1000 people entering in 
between 4:45 and 5:00pm or over 3 shifts...  Makes an incredible 
difference
(over 24 hours on a friday it could be as low as 1 users per minute or a 
focused timeframe could be 70 per minute.  We just finished analysis for 
a corporate wide timeclock system for the plants.  Usage spiked at the 
start and end of shifts and a half hour each way.  We are also in 
different time zones, so it spread out nicely...


Q#4 - We are MySQL and Oracle (Guess which one is cheaper?)


Q#5 - Struts good, especially if you are just getting started on the web

JSTL does address this -- see the  tag, with nested  and
 tags.  Although this is slightly more general than if-else,
you can use it to simulate if-else without having to learn another tag.

Re: Login Question

[Eddie Bush]

Ok, Vic, but what if you want to "let" the user login instead of "make" 
the user login?  CMA won't allow that, will it?  ... at least, not 
without a nasty work-around.  Do you have a solution for this scenario? 
 Let me explain let/make:

let:
The user may login at any point they choose.
This (explicitly) involves CMA

make:
The user has requested a restricted area and must login to access it.
This (implicitly) involves CMA

Crag had mentioned that spec 2.4 would make available a "logoff" 
functionality that a person could employ when using CMA and invalidating 
a users session.  He eluded to no equivalent for logging a user in 
though.  Ideally, a login implementation would allow the developer to 
(programatically and perhaps declaratively as well) specify where the 
user should end up - ie where they should be forwarded/redirected to.

Does basicportal handle this?  Does it do CMA on a "let" basis?

Thanks!

Eddie

Re: ERROR -- Must specify type attribute if name is specified

[Eddie Bush]

Have you tried examining the source of the generated page? :-)  I 
believe the name you will get comes from your form-bean declaration.  In 
your case (View -> Source to double-check me ;-) the name would be 
ldapsearchform.

Chuck has a really good book you should read ... buy ... advocate ;-) 
 (not necessarily in that order)

Don't specify the name for your form in the html:form tag - use whatever 
name you want to use in the form-bean declaration.

struts unwillingly submitting form when using javascript to validate

[Brian Steele]

Hi all,

Thanks in advance for any help.

Has anyone encountered an instance in which struts 1.0.2 submits a form without a 
submit button or a javascript call to submit()?

I'm using javascript to validate my form.  This is an extensive library of validation 
functions i've built up over many years and is fully tested, reliable, etc.  In short, 
i recurse through the javascript DOM to find any fields that require validation.  If 
the required fields pass the validation, I call "document.forms[ xx].submit()" 
otherwise an error message is displayed via an alert popup and no call to submit is 
made.

Somehow Struts is submitting the form anyway, even when I have no submit button or js 
call to submit ANYWHERE on the page.  The server logs show that struts starts 
processing the post after the javascript finishes (and no submit is called).

I'm running this on JRun 3.1

Here's the relevant code:


...

  3 is the dom order of the form (4th form on page)

First Web Application: Really Need Help

[vivek shrivastava]

Hi to all,

I need really an urgent help. I have been given opportunities to build my 
first web application. It is a very simple application. It is basically a 
kind of time tracking application. Using this application a employee can 
enter the information for pay period (like any vacation sick, jury duty…..) 
and submit this for supervisor review. Supervisor is going to review and 
approve it. Once supervisor approved the information for a employee then 
employee can not change anything for a pay period. Finally few report based 
on the information. There would be around 1000 users who are going to use it 
probably on Friday only.


I am sun certified Java programmer. i have been working in application 
development since last 6 years. I never build any web application. I need 
help to figure out some basic things. Please advise me ASAP.

Q#1
What is the best hardware for me keeping in mind that 1000 user is going to 
use it probably on Friday only?

Q#2
Do I need separate hardware for database or I can use same machine?

Q#3
Which server is best for me (like weblogic , websphere, )? What is the 
difference between websphere application server and apache webserver? How 
does this whole thing works? Probably we are going to use IBM’s tool.

Q#4
Which database?

Q#5
Is Struts helpful for this kind of small project?

Q#7
Does websphere  work well with struts?

Any advice you guys think would be helpful for me are most welcome.


Please help me ASAP.

Almost any with 1.5 gig of RAM. A cheap PC on Ebay with enough RAM. That

If you get a mentor who deployed Struts before, it would be cost 
effective. Why not build an Swing/AWT application/applet first (since 
you have 6 years) as a prototype with a delegated DAO and then port to 
web app?

You could always start with the example webapp that comes with Struts --
it's named (gasp! :-) struts-example.war -- just drop it in to your
servlet container and run.  The source code is included.

Among its many other links, the Struts Resources pages have links to
worked-out examples .

Nearly every article and book referenced here also has worked out
examples.

RE: [OT] What do you do with your SQL?

[Dan Petrie]

Hi Chris,

You may want to explore the idea of a DAO Factory.  We currently use such a
mechanism to retrieve a runtime interface to handle all database
interaction. The implementation of the interface (i.e. class name) is
specified in a properties file that is read at deploy time.  So...to handle
multiple clients you would simply need to implement this interface for the
client and specify the implemented class name in the properties files that
the DAOFactory reads from.  This allows you to keep the structure of the
application in tact with only needing to modify a properties file when
building the app for the individual client.  The business object classes
would then retrieve a DAO interface from the Factory.  This could work as
follows:

InterfaceName interface =
(InterfaceName)Class.forName(FullyQualifiedImplementedClassName).newInstance
();

We currently use this to handle multiple database servers (Sybase, Oracle,
etc) for our apps.

I hope this helps.

Subject: [OT] What do you do with your SQL? 


Hi all, 

Been a while since I last wrote, but I've been lurking to observe all the
crazy antics. :)  Anyway, I've got a question of an [ot] nature that I
believe you folks will have an answer for. 

Our application is highly data-driven and as such a lot of our "business
logic" is written to build SQL statements and handle query results.  Pretty
typical stuff.  Using Struts we pass data objects to a stateless session EJB
where all the SQL is directly embedded into the java source one way or
another.  

We're currently converting this custom app into a product. As such, we need
to be able to have easily modifiable SQL statements without requiring
recompilation of code.  For example, if client A decides to buy our app and
they have xyz infrastructure or business rules, we need to be able to easily
modify sql, hints and the like while also supporting the client-specific
sql, hints, etc. of client B.  

A lot of our SQL is built on the fly so using properties files may be a
little cumbersome, though certainly not beyond our means.  I have other
ideas floating around, but I'd rather just hear yours - any suggestions? 

Thanks,

Chris

Re: How do I navigate from one subApp to another in Struts1.1?

[Troy Hart]

Craig,

What do you mean below??? I am trying to understand how sub-applications
work and I thought I had a handle on it, but I am now confused. Why/how
are you bypassing the controller servlet when using



Can you tell me where my understanding of the this process breaks down?
I will spell out the major steps that are related to the sub-application
stuff as I see it:

1) A request comes in to ActionServlet, which inspects the request path
to determine the sub-application to use (which may be the default app --
sub-app prefix = ""), and fetches the application configuration for that
sub-application. 
3) The application configuration request attribute is updated to hold
the current sub-app configuration.
4) The process() method of the sub-app specific request processor is
invoked, which ultimately may end up forwarding to a jsp page that
contains 
5) html:link taglib code accesses the current sub-application
configuration to lookup the global forward "foo" and renders the link
appropriately. That is to say, if the current sub-app has defined a
contextRelative forward named "foo" that references an action in the
"goo" sub-app a link to some "goo" sub-app action will be rendered in
the browser.
6) Now the page is rendered and the user clicks the link to the "goo"
sub-app action.

Is this request not bound for the action servlet? And/or will it not
cause the action servlet to select the "goo" sub-application
configuration?

Also, I would like to be able to use the SwitchAction, but can not tet
it to work. Does it really work for you in practice? From what I am able
to gather no one has ever been successful at getting it to work and I
wonder what you are doing differently. 

I've posted a few messages already on this topic, but I've never had a
single response. If you could spare a few minutes to point me in the
right direction I would greatly appreciate it. The company I work for is
collaborating with 2 other companies to build a single struts
application for the department of defense EMall. As you can well
imagine, the sub-application features of struts are very desirable given
our situation.

Many thanks for any help I can get on this issue!

I suspect they're moving towards a "horses" theme for Apache stuff, 
like the dog theme for Mac OS stuff.  See 
 for

Simple write of a form property

[Jan Fetyko]

Hi all,

I was wondering if there is a way to write out a property of a form as 
text, so I could write something like .

I know there is a was to get it through some scriplets, but we are 
trying to avoid those in JSPs aren't we ?

Maybe there is such a tag between the Struts tags, I couldn't find it, 
is there ?

RE: [OT] What do you do with your SQL?

[Yang, Pedro]

Where you actually place your SQL logic (statements) sometimes has a lot to
do: 
(1) what DBMS your system is using (MS SQL Server, Oracle, to name a few); 
(2) what DB development resource and knowledge your team has. 

If a right DBMS is used, with the sufficient DB knowledge, the stored
procedures can be a good solution. 
The common pitfall with this approach is to hardcode the SP name and
parameters in the Java codes.  To avoid this problem, you can store the
values in a xml file.

Think about it the other way, make your application information driven.

For example:
Select * from rules where client = a

Think about it for a bit with a SQL expert (SQL Expert == someone with 7

How to identify the common Forms?

[@Basebeans.com]

Subject: How to identify the common Forms?
From: "Hu Ji Rong" <[EMAIL PROTECTED]>
 ===
Hi, all

We are creating a web based Data Maintaince Tool with EJB and Struts. It's
used to CRUD the domain objects in database.

Here I have a few questions :
1. Is it a good idea to use EJB to do that? I found it's quite fast to
create entity bean to represent those domain objects.
2. Each domain object is quite big, contains several tables, and more
important is they have some shared attibutes (tables). E.g. All entities has
an dependent object: DocumentSource. That's all entities have some records
in table DOC_SOURCE. So in the web UI, all entities has a link to
doc_source.jsp, which has a DocSourceForm.

We put the DocSourceForm in session scope because user want to see all the
data when they navigating from page to page. Now the question is: how to
defferentiate the DocSourceForm for different entities? since they are share
the same doc_source.jsp and DocSourceForm.

What is solution for that?

Thanks in advance.
JiRong

Depending on how aggressive your schedule is, consider
getting outside help from someone who has developed
web applications before for this project.

If that's not an option for you, consider getting some
formal training in web development issues before you
start designing or implementing. It would go a LOOONG
way.

It can backfire, but this one was less of a risk than I usually take, given that 
Struts is standards complient. My boss is pitifully grateful when I do ANYTHING that 
is standard, so permission was quite forthcoming. (I actually work in our standard

Hi all, 

Been a while since I last wrote, but I've been lurking to observe all the
crazy antics. :)  Anyway, I've got a question of an [ot] nature that I
believe you folks will have an answer for. 

Our application is highly data-driven and as such a lot of our "business
logic" is written to build SQL statements and handle query results.  Pretty
typical stuff.  Using Struts we pass data objects to a stateless session EJB
where all the SQL is directly embedded into the java source one way or
another.  

We're currently converting this custom app into a product. As such, we need
to be able to have easily modifiable SQL statements without requiring
recompilation of code.  For example, if client A decides to buy our app and
they have xyz infrastructure or business rules, we need to be able to easily
modify sql, hints and the like while also supporting the client-specific
sql, hints, etc. of client B.  

A lot of our SQL is built on the fly so using properties files may be a
little cumbersome, though certainly not beyond our means.  I have other
ideas floating around, but I'd rather just hear yours - any suggestions? 

Thanks,

Chris

right?  I guess the solution I'm looking for is JDBCConfigRealm (not 
written, obviously) that would make use of some configuration to specify 
where a person authorizing in a "let" manner would go - and give an API 
to allow "let" authentication to occur - specifying an over-ride 
destination.  Obtaining the behavior I mention would necessitate either 
a nasty work-around or a custom realm (ie using Tomcat) implementation, 
am I right?  I'm not trying to belabor the point - I'm just trying to 
get a crystal-clear view of options.

(couple more comments below)

Thanks!

You know, I downloaded it but I haven't taken the time to "get my hands 
dirty" with it yet... er, haven't _had_ time I should say :-)  That's my 
obstacle to contributing too :-/  I should probably spend less time on 
the lists ;-)  I guess that's a form of contribution too though.

[OT] What do you do with your SQL?

[Assenza, Chris]

Hi all, 

Been a while since I last wrote, but I've been lurking to observe all the
crazy antics. :)  Anyway, I've got a question of an [ot] nature that I
believe you folks will have an answer for. 

Our application is highly data-driven and as such a lot of our "business
logic" is written to build SQL statements and handle query results.  Pretty
typical stuff.  Using Struts we pass data objects to a stateless session EJB
where all the SQL is directly embedded into the java source one way or
another.  

We're currently converting this custom app into a product. As such, we need
to be able to have easily modifiable SQL statements without requiring
recompilation of code.  For example, if client A decides to buy our app and
they have xyz infrastructure or business rules, we need to be able to easily
modify sql, hints and the like while also supporting the client-specific
sql, hints, etc. of client B.  

A lot of our SQL is built on the fly so using properties files may be a
little cumbersome, though certainly not beyond our means.  I have other
ideas floating around, but I'd rather just hear yours - any suggestions? 

Thanks,

Chris

Digester finding file, parsing, not outputting any debugging info

[Nelson, Laird]

I'm going 
bats.  I'm creating a new Digester instance, setting its debug to a 
non-zero value, and telling it to parse a URL that I validate exists and matches 
the rule templates I've added to the new Digester instance.  Digester's 
parse() method fires, doesn't throw an exception, and nothing (no debugging 
information) gets output.
 
Are there 
any standard Digester checklists I should be going through?  Is there some 
step I'm obviously missing?  I've used Digester many, many times in the 
past successfully.
 
If folks are 
interested, I'll post my code and my config file.
 
Cheers,
Laird

Solved the problem (of course; which is why I usually post to this list; the
minute the email goes out I find the answer...).

I had a file like:


  


My rule patterns were like:

"*/a/b"

...which of course don't match anything.  They should have been:

"*/b"

...for my purposes.

Cheers,

basicPortal comments

[Mete Kural]

Hello Vic and others,

The basicPortal presentation was very nice. Thank you
for your efforts. I think providing verticals for the
J2EE community would be a very good effort, because
after all we're doing very similar things over and
over. Everybody is implementing user authentication,
shopping cart/web store, content management, site
administration, etc. The basic 80/20 rule applies here
also. 80% of our requirements for the above listed are
the same, while 20% of it is specific to our business.
Each one of us is implementing that 80% on our own
over and over again. Instead we could join efforts and
implement that 80% together, then finish up the rest
20% on our own, which may be very specific to what are
business is involved in. This way we can save time,
money, and improve reliability and performance.

Are you inviting other contributors for basicPortal? I
would be happy to help.

Thanks,
Mete Kural

Re: SSL+Tiles

[Eddie Bush]

I wrote Stever Ditlinger and he sent me a jar of a version he has that 
is 1.1 compatible!  I replied asking him for a URL, and hope to have the 
URL to post here soon.  I also asked if he could tell me if there was an 
accompanying article - I _know_ I've seen it somewhere.  I just cannot 
find it!

If you'd like me to send you the jar via email, please contact me 
(directly) via email.

Thanks :-)

Eddie
