Record-locking in J2EE/JSP/Servlet apps?
How are any of you solving the problem in the stateless webapp context where two users pull up the same record from a database in a JSP page, and user one changes the address and saves but then user two, who has the old address on his JSP page, changes the phone number and hence over-writes user one's address change? Are you locking the record in the back-end database and then implementing the SessionBindingListener to release it when the session expires, if the user leaves the webapp without logging out?

Re: Dreamweaver JSP
Martin, "Of course, your message implies you are a consultant, and you don't say anything about documentation or maintainability, so perhaps our goals are not quite the same." You also forgot the biggest benefit to "doing things right", as opposed to this Model 1/VB/RAD approach: code and pattern reuse. This, along with the two items you mention above, are things that clients who use consultants normally aren't savvy enough to realize they're missing, and how much money they're blowing by having the consultant come back in and re-develop the same cookie-cutter code over and over for each app, or to later try to extend or enhance a mish-mosh of spaghetti code that was "generated" by their productivity tool. There's a good balance though, we all know the answer to this argument in our heart when we put our zealousness aside. Sometimes I use WebSphere Studio to quickly bang out a prototype because it's wizards can get a database web app up and running quickly. But I'd never put that code into production because it is so tangled and does things like throws the ResultSet into the session for page navigation.

HTML/JSP Reporting Tools?
Has anyone used any tools for doing reporting in conjunction with web applications? One of our developers is pulling her hair out trying to code this capability. When she prints the report that she has output to the browser, often rows are repeated from the last line of one page to the first line of the next in the HTML table. Also, sometimes text is chopped off at the right margin, so she'd like to have some control over the margins. Does anyone know how to solve those problems? I see it a lot when I print HTML documents, etc, but with a report it is not a good thing to have those rows repeated. I'm wondering if anyone has used tools like Crystal Reports and how easy it is to integrate those into a webapp. The data is in Oracle tables.

Re: Cant Save .jsp file!!
Jennifer, I'm surprised nobody told you yet that the ".txt" extension was added because when you saved it, right there on the dialog box in front of you, it probably had a combobox for the file type that was set to "Text (*.txt)". If you tell it to save it as .txt, it will. If you want it to save as something else, change that option to "All files (*.*)" and it won't do that anymore.

Re: connecting to mssql
Julia, maybe you have lots of time on your hands with nothing to do, but I find that wading through the hundreds of messages in this list and the others that I subscribe to each day takes a lot of time. I have work to do as well as the small amount of time I can take to keep up with these technical resources. If the large number of off-topic messages were removed, it would take a LOT less time to keep up with the list. Each message takes a small amount of time to scan and delete. Multiply that times the number of messages and the number of people reading this list and you come up with a huge amount of wasted time. Just because someone was too lazy to take the time to fire up google.com and search for 'java barchart' or 'SQL Server driver java'. In answer to the other guy's comment - people don't have to register for every obscure list out there to ask questions on topics like barcharting. You could use that same rationale to ask questions about legal issues, sex, etc here, since it is certain that some list members would have such information.

Re: A component that generates barcharts.
In Joseph's mind, he is performing a service. He is taking the role of the curmudgeon here that lets people know when they do things that degradate the list, in order to make the list better. In that role, he is taking the heat on himself from people like you that will be upset because he isn't being "nice". I don't like the pollution on the list and get aggravated by people that are lazy as well, so I see what Joseph is doing as necessary. At least he's still answering the question, to his credit. Inevitably though, this is an ecosystem out here, a microcosm of society and there will be all types. Let's just keep that in mind and deal with all of them as best we can and not generate another thousand messages/flames at each other every time this happens. It always has and it always will. By educating people, perhaps Joseph will cut it down and this will stay as on-topic and enjoyable as others (Struts). Some people don't know what they've done wrong until Joseph steps in - for example the guy who replied to one message but changed the subject line to create what he thought was a new thread. It isn't, it's an off -thread message inserted into the original one and that upsets people who have threaded readers. Now maybe he knows and won't do it again.

Must hard-code context path always?
We would like to have our web applications run on different servers with perhaps different web application paths. For example, if I set up the web app in WAS 3.5 with the web application web path set to /myapp, I have to have that name 'myapp' in the webapp descriptor files as well as in any URIs in JSP or servlets prefixed to that, even though they are relative. For example, in the descriptor file: default-page uri/myapp/EntryTableResults.jsp/uri /default-page in the JSP: FORM method="POST" action="/myapp/servlet/com.myco.DataEntry" and in any forward/redirect in the servlet, same thing. Can't the application be coded or the admin set up so that these things don't have to be hard-coded into the application source files, so for example I could put it on the same server as 'myapp2' easily without having to change all of that? I was told that this is really a design issue coming from Sun. The Java Servlet Specification, v2.2 describes the contextPath as being at the start of the URI (chapter 5), and that is what is used to distinguish which web app should handle a particular URI. And because of that, the contextPath is bound to get into the development code, and that's just the way it is. It prevents us, for example, from putting the webapp out on our production server in a different directory and with a different context path, doing the final run-through to ensure that it is running correctly, and then copying it over to the 'real' directories (and previous version) to turn it on in production. Of course, we would have already fully tested it on a test server, but this would be to make sure there aren't any environmental issues on the production server before turning it on for real.

Re: virtual host setup in WAS
This is well detailed on IBM's WebSphere web site as well as in the product
documentation that you get with WebSphere. Just go to the admin console and
use the help menu and search for virtual host. There is better info on their

Re: Whats up with all these out of office replies??
/soapbox I think that the gripes happen pretty infrequently and especially with a subject line like this thread has, they are easy enough to ignore because it is obvious that they are off-topic. They do serve a purpose in that they help to educate others as to what appropriate use of the list is. Some may not be aware that they are annoying others. That said, if I could add some of my pet peeves to the list: Posts filled with letters substituted for words - i.e. 'u r doing this wrong'. I know it's anal of me but I find it annoying and hard to read. Cute, but how hard is it to type the whole (short!) words? It gives the list an AOL chatroom full of teenagers feel (no I don't hang out there, but I have teenagers at home!). English is my first language and I hate to see it mangled that badly. It also gives the poster an 'uneducated' impression. Anybody who codes should be fairly good at keyboarding, so this shouldn't be necessary. Posts that don't put have a subject line. Posts that just say "Thanks!" or "Do I know you?" or some other acknowledgement that is irrelevant to 99.9% of the readers. Posts that contain excessive content of previous messages and list footers copied 99 times. (I'm probably guilty of that sometimes!). Aside from all of that, the list is awesome : ) /soapbox === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Re: Dynamic Authorization Content
I'll check into that. It sounds like maybe overkill to use EJB to do this simple dynamic page so I don't know if that will fly. I've been looking for an excuse to use/learn EJB though :) I was thinking more in terms of some simple JNDI code in a servlet to iterate though any subdirectories under the web root for this web app and check to see if the current user is authorized to use each one and if so, add the link to the page. Does anyone know if that is a viable approach? I don't know JNDI either, but will dive in if that is the solution.

ClassCastException on session.getValue()?
We have a servlet that checks if there is a session and if so, checks for a session value "UserInfo". If both aren't there, it puts its URL into the session and calls the LoginServlet. After the user logs in, the LoginServlet populates a class 'ExtranetUser' and creates a session, and puts it in the session as "UserInfo" with session.putValue( "UserInfo", userInfo ). userInfo is a newly instantiated and populated ExtranetUser object. It then extracts the URL from the session and redirects back to the application. Back at the app, the session and "UserInfo" object are there, but the following call fails with ClassCastException: ExtranetUser user = (ExtranetUser)session.getValue( "UserInfo" ); How could this be? There is only one ExtranetUser class on the system, so there's not a chance there are different versions. If we change the cast to (Object)session.getValue "UserInfo") and then do a user.toString, we get "com.hersheys.login.ExtranetUser@314320" so we know it's the right class/package!. We tried fully qualifying the cast and the declaration above with com.hersheys.login but that doesn't make a difference. The application is in a webapp under IBM WebSphere 3.02. We know that both servlets can pass info through the session because the app puts its URL there and the login uses it to redirect back and that is working. We've been trying to figure this out all day. Can anyone help? Thanks! === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

usebean autocreate Param?
In JSP .9x, I think there was an autocreate param in the BEAN tag to specify whether the bean should be created with the null constructor if it wasn't found in the scope identified by the scope param. I don't see that in any of the descriptions of JSP 1.0 jsp:usebean. Is it automatic now? What if you had a page where the bean SHOULD exist?

Re: your opinions about servlets + JSP, Brazil, WebMacro and othe r co mpeting technologies
Jim - Amen! I think the "immaturity" is with a lot of IT management. They expect JSP to be "simple" along the lines of HTML. The tools aren't quite there yet but getting better now that J2EE is a reality. You touched on one thing that I complain about - as part of my job as a web application developer, I'm also expected to do the admin/config/troubleshooting for WebSphere. Management often just doesn't understand that application servers (at least good, full-featured ones) are complex pieces of software that require a middleware tech as a full time position to be able to develop expertise enough to be really good to tune them and tell when and why things go wrong. I'm having enough trouble keeping up with the technical and architectural changes in server-side Java development, let alone learn enough to bring my self above a novice level as far as the app server and all of the changes that are happening there.

There aren't many GUI tools that support JSP and the ones that do like Dreamweaver are first generation and need more work. From the perspective of a Java developer working on web applications and user interface design, JSP is a godsend and is very mature technology. This is especially true if you are working on enterprise applications. There isn't any other technology that even competes on the same level with JSP, servlets and EJBs. I don't work with GUI web development tools. I rely on our web developers to do that and I add the Java and JSP tags that they can't handle. There are at least 5 books on JSP and even more on servlets. If you can't configure the tools maybe you are out of your depth and should employ the help of a system admin.

Re: Servlet Controller - stopping other Servlets calling action S ervl ets
Easy - the controller servlet is the ONLY servlet in the application. It calls "action classes" to carry out tasks, but there are not servlets. They are "servlet aware" in that they accept servlet artifacts in their execute() method as parameters, so they can access parameters, etc. But to answer your question, some of the beauty of this is that the controller is the only servlet, hence all security, session checking, etc happens there.

Re: JSP and UML - or: Modeling a JSP application
Heiko,
I went to a week-long Rational OOAD class and couldn't figure out how to
apply the UML to my web app. So I had a design session with Rational on my
web app and I noticed that the consultants were all peeking in this book. I
asked to see what it was and it was the book that Bill mentioned by Jim
Conallen of Rational ("Designing Web Applications with the UML"). It is an
excellent book. You will also need the Web Application Extensions (WAE) from
Rational's web site for some artifacts to use for server pages, client
pages, etc. Web apps are tough because a servlet for example can manifest
itself as a boundary object by the HTML that it generates (and becomes a
whole different object) and a controller object by nature of it's handling
of HTTP traffic, parameters, and other servlet-type jobs. Conallen provides
a model to handle that nicely. The book also has one of the best tutorials
on the whole web paradigm that I've seen.

Hi,
has anybody ever tried to model a JSP application in UML? I have not
worked very much with UML so far, but I would like to have a means to be
able to design my JSP applications before programming begins.
I think a big modeling problem would be the parameter passing between
servlets and JSPs, which works by storing key/value pairs in request
objects, sessions etc. BTW: I think this kind of parameter passing sucks
anyway, because it is neither type-safe nor is it noticed (by the
compiler!) if you simply don't pass any parameters at all :-( Wasn't
Java said to be a type-safe language? We might as well be programming
Basic...
So, how do you all design you applications? Or are you just hacking away
:-)?

Is there any different btw this? Can anyone tell me which method is good? Passing the big bean, will it be slow down the performance? or use more memory? Since the beans all stay in the server's memory, there isn't really much performance difference between one big bean and two small ones. You should design your beans based on object oriented design principles, rather than worrying about performance. The "rule of thumb" that I use is if all the information is about one thing (like an employee in your case), *and* there is only one copy of all the fields, I make it all one bean. On the other hand, if there is a "one-to-many" relationship (in your case, one employee with multiple payments), I would make two different beans -- Employee and EmployeePayment -- and then store one employee bean and as many payment beans as I needed to. Sorry my english, hope you can understand. Louis Craig McClanahan === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Re: JSP Coding standards
There is an awesome book out, a little green book called "The Elements of Java Style" that our organization has adopted as it's standard with very few changes. It is a collaboration by a number of notable figures, one of which is Scott Ambler. You can visit Scott's site (ambysoft.com?) and download some papers there on standards, but I suggest you get a copy of the book for each person in your organization and any revisions you might make.

My name is Sergey, I'm from Boston, U.S.A. and I've been living with my family in India for the last 5 months. To come to India was always something that we wanted all our life, a "dream from childhood" but, unfortunately by the age of 20 life responsibilities force so many of us to abandon our dreams and goals in favor of a monthly paycheck. We get trapped in a daily routine because we were educated to go to school, get a job and work towards retirement. Several years ago we met a company with exclusive, life changing products, most generous marketing plan and honest and caring leadership that WANTED us to dream and was willing to teach us how to achieve our goals. Of course, we ourselves were willing to make some changes and learn some new skills, and that helped us to achieve the top management position in a record short time. We came to India as soon as our company opened operations here, and we are looking for some dynamic and entrepreneurial people to whom we could pass our experience and knowledge. Let me give you a few facts: -recently opened in India and already up to Rs 28 crore per month in sales! -fastest growing company in the world in nutrition and weight-control industry -unique herbal-based products approved in 49 countries -publicly held company traded on the Nasdaq Stock Exchange -over 20 years on the market -$1.85 Billion dollars in sales in 1999 -30+ million documented satisfied customers world-wide This is not a situation where you must quit your job and overnight have a new profession. Over 90% of us began strictly part time, putting in whatever hours our schedules allowed, working around our children, our jobs and committments etc. When our part time incomes from this business matched or exceeded our current jobs, many of us made the decision to do this full time.

Re: Another even more trivial model 2 question
Craig,
I noticed here and in another message from you that when you do the
getServletPath to get the "/listCustomers.do", you then strip off down to
"listCustomers" and then search a hashtable to get the action class name,
then search another hash table by that to get the class object itself. Why
can't you just make the part before .do the action class name itself and
save that extra step?

Well, I actually got the controller - Action class model working
appropriately (Thanks to all those who answered all these trivial

What sort of methods are others out there using to obtain a "match part"
from the requestURI? I am ripping the string apart (in a very very poor
way) and reconstructing a "match part" by eliminating the server
information
and virtual directory information used in the application deployment. I
was
just wondering what some others have come up with because I am fairly
positive that mine sucks parts of the body that one should not mention on
a
list such as this :).
The approach I use is to map my controller servlet to a filename extension
with an
entry like this in the web.xml file:
servlet-mapping
servlet-nameMyControllerServlet/servlet-name
url-pattern*.do/url-pattern
/servlet-mapping
which associates the ".do" suffix (implying "go do something") with the
controller
servlet. Now, my JSP pages can submit to a URL like "listCustomers.do" or
"addOrder.do" and my controller servlet can do this:
String matchPart = request.getServletPath();
int extension = matchPart.indexOf(".");
if (extension = 0)// Strip off the extension so I can change it at
will
matchPart = matchPart.substring(0, extension);
Given the two above examples, I would get a string of "/listCustomers" or
"/addOrder" from this code, and I can use the matchPart value to look up the
appropriate action class.
This isn't anything urgent as I have everything working, I was just hoping
to see some alternative examples so I can see how mine stacks up (or
doesn't).
Thanks again for all the help to all who have contributed to the Model 2
discussion :)

Re: Design choices: JSP Javascript

Re: Model 2 - Instantiate Action Call doGet()?
Craig,
I understand. One thing, however - I still was going to have the main
"controller" servlet that was going to do the routine things - check for
login, check for session, etc. Then *that* controller servlet was going to
instantiate the Action servlet and call its doGet(). But as you say, that
would be overkill since the Action servlet would carry a lot of unnecessary
baggage.
Am I right that your Action classes then just each extend the Action
interface and have just the one perform() method? And the Action class is
the one that forwards to the correct JSP page?

Would it be better to just make it a servlet and instantiate it and then

In my case, the Action interface (not really a class) is *not* a servlet --
it has
one method:
public interface Action {
public void perform(HttpServlet servlet,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException;
}
It is certainly possible to make each action a servlet -- and then it's even
possible to call them directly instead of going through a controller.
However,
I've found the following disadvantages to this for my own apps (your mileage
may
vary):
- You lose the fact that the controller servlet
can perform common logic (such as making
sure you've logged on) for all requests -- you
would now need to make sure that this is
done in every single action servlet.
- You tend to create subtle dependencies between
the presentation logic and the business logic
based on the URLs being used. I find it easier
to avoid this temptation if I'm using an action
class that is clearly not a servlet.
- If your action procedures don't need the full
lifecycle support (init and destroy methods) that
servlets support, making them servlets is overkill.
(If they do need this support, maybe you should
look at designing them to access shared servlet
context attributes that are initialized when the
server starts up instead?).
For some folks, action servlets works just fine because they don't need a
single
point of management. Personally, I find it easier to separate roles, and
design my
action classes as "adapters" (in Design Patterns terms) between the
parameters
coming in with the HTTP request, and the business logic beans or EJBs that
actually
do things.

Now it has been decided to rewrite the JSP as a servlet because we don't have the time to debug the memory hogging issue. We have a deadline. The languages (JSP or whatever) and concepts like CORBA are all trying to change the way we work but the vendors don't create good products. So we end up blaming the language or concept. Now the ASP or Microsoft supporters in our organization have started blaming Java and JSP because it is JSP that didn't work and it is Java that is slow. I have faced the same problem with NetDynamics and PowerJ. When the early release of PowerJ was bug ridden my manager starting blaming Java. Even now we don't have good remote debuggers for servlets. We don't know what the request is or the response from the web server is. Sometimes I had to use a packed sniffer to look at the request and response. I am sure that this is not what we want.

Model 2: Persistence Layer?
In our current app, which we want to move to Model 2, we have packages to hold model, view, and controller classes. The view package holds servlets that emit html to build/handle the HTML. The model package holds "pure" business classes, lightweight ones to represent Account, Product, Region, SalesRep, etc. The controller package holds a Datastore class that handles all interaction with Oracle for the app, as a persistence layer. An example would be a methods like: Datastore.saveCustomer( Customer customer ) Datastore.saveRegion( Region region ) The servlets call this in response to form submissions, etc. The pure 'model' classes of course, have no knowledge of the view or controller, they are just passed around like a cheap prostitute. How is the persistence handled in your model 2 apps? It seems that to follow what may happen if we get to EJB, we need a persistence class for each class in our 'model' package, such as AccountDB, ProductDB, RegionDB, etc. Then we have two places to make a change if a class gets a new property, for example. It is even more if we come up with another platform to persist to, such as SAP or another ERP. Is this the case? I'm looking for a clean way to handle this.

Job Opportunity in Hershey, PA
My co-worker, co-Java developer, left the company a few weeks ago to pursue an entrepreneurial venture, so we're posting this position here at Hershey Foods, in central PA. This is an awesome company (especially if you like free candy!) in an area that has the best of all worlds. It has beautiful, open countryside, mountains, fishing, hiking, hunting and all the benefits of a rural environment, especially LOW cost of living, plus the urban city benefits of the state capital of Harrisburg just 15 minutes away and larger city benefits such as Baltimore (1.25 hours), Philly (1.5 hours), DC (2.5 hours), NYC (3 hours) and Pittsburgh (3 hours). The ocean (Atlantic City, Ocean City Maryland, Seaside Heights NJ, Rehoboth Beach DE) is only a few hours away (about 3 for each). The Susquehanna River runs right through here for you jet-skiers and river-boaters. Right across the street from us is Hersheypark, a great amusement park with something like 10 roller coasters now that is not only a place to have a blast with the family (or at lunchtime!), but a great, fun, safe place for your kids to work (mine do). Check the URL for Hershey attractions at http://www.hersheypa.com and Hershey Foods at http://www.hersheys.com. We have pro hockey (Avalanche affiliate Hershey Bears), pro soccer (Hershey Wildcats) right here in town and pro baseball (Harrisburg Senators, Expos affiliate) and indoor soccer (Harrisburg Heat) right in Harrisburg. Also tons of concerts (saw Roger Waters, Black Sabbath, Dave Matthews, Fish right across the street and front-row tix for Allman Brothers on 6/20!). We just hosted the Olympic Soccer qualifying tournament last week, again I can see the stadium out the window across the street (USA lost to Honduras in the finals but still qualified). On the tech side, we've standardized on IBM VA Java EE, WebSphere, and WebSphere Studio. This is a chance to get in the game early here. We've been doing Java development since 10/98. It was just me and the other dude (who left for an entrepreneurial venture) and we've just trained 8 of our PowerBuilder folks. We'd like more experience. We're doing server side J2EE Model 2, servlets, JSP, beans, and moving to EJB at some point. Modeling in Rational Rose. So here's the job desc, give me a shout if you're interested.

Re: More on Model 2 architecture...
Craig, Is your "action class" a servlet or is it a bean that is "servlet aware" by importing the javax.servlet.http classes and knowing how to forward to the correct JSP page? I want to try this design with a controller servlet for a small application, it sounds great. Do you have any type of UML diagram, such as a sequence diagram, that shows the flow and coordination between the controller servlet, action class, and business/database beans?

I believe this is what we have been suggesting, which means I don't think I understand what you are asking. The action class initiates the appropriate business functions, stores results as JavaBeans -- either in the request or the session, depending on how long you need them -- and then forwards to whichever JSP page should be used to display the results. this way..i don't need , if for example i have to manage lot of JSP, to have a config file in which i have to put all the JSP URL.. and neither to forward the request back from the Servlet to the JSP's... i would like to have opinion on that from as much people as possible.'cause i would like to know what are the possible drawbacks The reason that I use forwarding back to the JSP page is because: * The beans I use don't know anything about the web -- they are just JavaBeans. They don't import any of the javax.servlet classes, and they don't generate HTML. * The action class's sole purpose in life is to execute whatever business logic is required. Creating the output that results from executing this is the sole purpose of a JSP page, which is why I forward control to the appropriate one. * Sometimes the "appropriate" JSP page is different (for the same input) based on what the user entered. For example, assume you have a form that has fields for a record you want to store in the database, but you have some validation logic (for example, a postal code entered by the user must be valid) that can only be checked on the server. If the user made a mistake, I want to forward back to the original input form (with an error message) so that the mistake can be corrected. If the user did not make a mistake, I want to have my JavaBean store the result in the database, and go on to the next piece of the application. * The JSP page that displays the results should not care how those results were created -- it should only know things like "if I want to display the name and address of my customer, use the getName() and getAddress() methods of the CustomerBean with id 'customer' from the session." This way, you can change the visual appearance of the output pages without messing with the logic that created the beans. thanx in advance and best regards marco Craig McClanahan === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Pop-Up Form Window?
I'm here late on Sunday night trying to get a project done for this week, I have to demo it on Tues and there is one last part I can't figure out. My main JSP page has a list of items on it. There is a small graphic next to each item in the list that says "Order". When the user clicks that, the item number and description are sent to a servlet which pulls them from the session, creates an OrderItem bean and puts it in the session, then calls the JSP page with target="_blank". This page has a form that shows the item number and description and asks the user for the quantity. I want the user to be able to press the submit button to submit the order and close the window. If I put onSubmit="window.close()" in the form tag, the form data never gets put in the session. If I take the onSubmit out, it works great but the extra window sticks around and the item list redisplays there. How can I get the pop-up window to close and do the submit like I need?

Re: New article: The Problems with JSP
Jason,
I'm very interested in Model 2 and feel it's the "right way" to integrate
these technologies and also removes most of your arguments against JSP. I
think Model 1 is wrong for the reasons you state, but that's not a "JSP
problem", it's a misuse of JSP depending on the circumstances or application
of course. Can you say when your second edition will be out?

Sure, you can mistype the %! with %, but if

Easy enough for Java programmers. I'm OK with JSP being "a cheap way
to write servlets". I've used it that way myself. However, when you
get non-Java programmers into the mix people should be aware that there
are other options that might work better for them.
Is a template engine going to be part of the J2EE
specification?
No, nor does it need to be. Not everything needs to be in a
specification. Not everyone has to do everything the same way.
If your servlet uses a template engine, just include the engine
classes along with your app and it'll work everywhere.
alot of application servers will be supporting J2EE.
All engines support template engines, without any changes to the
server. No vendor-specific JSP bugs. :-)
How exactly is a template engine used anyways?
Whoa, you haven't used template engines. Perhaps you can go try it,
use both on a real site, then decide if you still prefer JSP.
That's what I did.
Is it a plugin to app servers, web servers, etc? I assume it would
be a servlet perhaps that parses the data sent to it returning back
a response? If thats the case, then I can see it added to a servlet
engine where an extension of say .wm (webmacro) is mapped to the
servlet engine, and thus passed on to the right
servlet to parse it.
Template engines are just classes like
com.oreilly.servlet.MultipartResponse that help you generate content.
You can have them serve .wm files if you like, such as when you're
doing includes.
In all honesty, I cant imagine why you, who wrote a book on
servlets, wouldnt use the JSP (or promote it) over something as
(to me) arcane as a template engine. Seems that JSP would fit right
along well with servlets, since its an extension to it.
JSP 0.90 I liked. It was an easy way to write servlets. Now JSP has
been targetted at the non-programmer and I don't believe it can succeed
well in that market, at least not without a great dependence on tools.
Maybe that'll be its ultimate savior.
I was looking forward to a new book with more info on JSP from you.
I guess thats not going to happen..is it? :)
In the second edition I'm demonstrating how to do "Model 2" using JSP.
That's arguably the best technique for JSP and belongs more in the
servlet book than the JSP book because it's servlet-centric.

Re: WebSphere 3.0 can't do jsp:include page=joe.jsp / ???
Remember that with WebSphere 3.0, the JSP level can be set for the server or the application itself. So you could have some apps set for JSP .9x, and some set for 1.0. Your server may have been set for 1.0 but the specific webapp (either default_app or the custom one you set up as myApp or whatever) may be set for .9x. You might want to check that.

Re: New article: The Problems with JSP
Let me add two cents here from my perspective of coming from servlets, and being a big proponent of MVC as we have HTML jockeys who are great page designers but NOT programmers, and being disturbed about the necessity of outputing HTML from servlets or using "fringe" technologies like shtml, etc. I recently started using VisualAge Java, WebSphere App Server, and WebSphere Studio and I can finally see the beauty and ease of how this all fits together. JSP, through the strength of its widespread adoption, has made it viable for companies like IBM to create these types of tools. In Studio, our HTML jocks don't have to write all kinds of arcane Java code or use arcane tags. They can design their pages visually as normal, plunking down graphics, tables, changing fonts, etc. But they can also choose one of our business components from a palette, such as our Customer object, drag it on the page, and from there drag a property of that class onto the page as a dynamic property. So they'd type in HTML "Welcome to our site " and then plunk down the dynamic property Customer.getFirstName() just after it. By using niche technologies you will never have open tools with this power. So the graphics designer can work effectively, the component designers can work effectively, and they can all work in harmony. Are there really that many people, especially non-programmer graphics designer types, hand-coding their HTML any more anyway? We all fine-tune by going to the HTML view, but the initial layout is done visually. There are other tools with this type of power that use template engines, such as CF, but they are very proprietary in nature and we won't buy into that. We almost bought NetDynamics two years ago but are glad we didn't for this reason.

Re: WebSphere 3.0 can't do jsp:include file=joe.jsp / ???
WRONG! I think this is incorrect. I use WebSphere 3.02 and it has JSP 1.0 as well as .9x. It defaults to .92 so you will have to change that, but I'm using JSP 1.0 in WebSphere App Server and WebSphere Studio, and VisualAge Java in the WebSphere Test Environment. Read the docs! There are instructions to change the default from .92 to 1.0.

Re: thin driver problem in jdbc to oracle.........
Your Oracle driver (probably named classes111.zip) probably isn't in your classpath. Your classpath should have something like "classpath=c:\orant\jdbc\lib\classes111.zip;...". Don't forget to read the install instructions for whatever driver you're using also. Some require you to put another zip file in that directory for NLS support, and some give you oci*.dll files to put in your windows/system32 directory. I would make sure that's all in place, and reboot if you changed anything, then try it. This is probably all in place on your NT server but not on your Solaris server. Keep in mind that if you're using the OCI version of the drivers (as opposed to the thin 100% Java ones), you need the right version for your platform (NT or Solaris) as the OCI ones are platform-specific.

Re: development decision
The beans would give your clients the ability to just design their own pages and pull the properties (info) from the bean and display it as they choose. We use IBM's WebSphere Studio, which has a really nice model for using JSP, Servlets, and beans together to accomplish sites like this. And don't forget XML - it is probably exactly what you need as far as just providing data to the page and letting the end-user of that XML file display it as they wish. You could develop a standard XML DTD of the data that your company provides to those clients. Bill Hines Hershey Foods -Original Message- From: Allan Joudrey [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 18, 2000 1:10 PM To: [EMAIL PROTECTED] Subject: development decision Hi all, I have been following the discussion on "Providing application resources" and have found it very interesting and helpful. I think a lot of good ideas came out in the discussion, therefore, I would like to put my current development plan up for discussion to see if I can receive any input. The development: A system that is used by many smaller companies. The mainframe holds all the user's information. Currently, an applet talks directly to the mainframe through a package on a linux box. This requires that all the companies use the same applet, with little ability to change the style to meet their company profile ( they can change pics only). Many of the companies want to develop their own unique sites. For this reason (and because I enjoy to work with servlets ;)) we have decided to go with servlets to process requests from the users. This will give us the ability to send objects (containing the user's info) back to an applet or put it in a HTML page. This will make the companies happy because they can use the applet or make their own pages. The problem: My part that I am not overly clear on what direction to proceed is with the companies that will make their own pages. They will be on our system and the dynamic data required will be placed in the HTML pages as they are requested by the users. I have thought of just giving them the required tags and a servlet will generate the pages dynamically by reading them in from a file. Someone mentioned that they used this method and when they switched to a jsp generation method that the speed increased 10 fold. I am new to jsp (really green) but would look at this if it is a good option. Would this require that I use beans also, or can I choose between the beans and servlets. Would beans be an option also ( I am also new to beans but not so green as jsp). An important point is that it has to be as simple as possible for the companies to hire site designers to develop their pages, and they can only receive basic templates of the info that they need to use to get the dynamic data from the mainframe. Security is the highest issue so we can't give out to much. If I haven't mentioned any import points to consider, please let me know. Any thoughts, and thanks for your input.
