question about best way to separate front-end code from back-end code
I am working with a software company that develops in Java. Some of the functionality involves interaction with users via the web. Some clients that use the software product would only like the back-end code and would like to implement the look and feel of their website on their own. In this case, we would like to provide a middle-tier set of classes to hand off code to other developers at clients. I'd like to figure out the best way to implement this middle-tier between back-end database processing and front-end GUI code. The question is whether Axis is the proper development tool. More specifically, does Axis provide a way to easily handle displaying, modifying and deleting data returned from a query to a database where the query returns more than one row; i.e., a result set? We would develop a middle-tier that would be responsible for getting the data from the database and then returning it but then a developer at a client would be responsible for displaying the data. Because of this hand off we are looking for a smooth and easy interface. Does Axis provide this type of easy hand-off? If not, is there another way we should develop this middle-tier? === To unsubscribe: mailto [EMAIL PROTECTED] with body: signoff JSP-INTEREST.

passing array to bean from JSP - platform issues
I've a problem I can't seem to find anything about...
I have a few JSPs with forms containing an array of input:
form name=inputform
bKeywords/bfont face=Arial, Helvetica, sans-serif
size=2bbr/b/font
1) input type=text size=70 maxlength=1024 name=keywordsbr
2) input type=text size=70 maxlength=1024 name=keywordsbr
3) input type=text size=70 maxlength=1024 name=keywordsbr
4) input type=text size=70 maxlength=1024 name=keywordsbr
5) input type=text size=70 maxlength=1024 name=keywordsbr
6) input type=text size=70 maxlength=1024 name=keywordsbr
7) input type=text size=70 maxlength=1024 name=keywordsbr
8) input type=text size=70 maxlength=1024 name=keywordsbr
/form
I submit this form to a 2nd JSP for processing...
jsp:useBean id='aBean' scope='session' class=my.pkg.ABean'/
jsp:setProperty name=aBean property=* /
The bean has a setter method which passes the parameter array into a List...
public void setKeywords(String [] keyWords) {
keywords.clear();
for (int i=0; ikeyWords.length; i++) {
if (keyWords[i].length() 0) {
keywords.add(keyWords[i]);
}
}
}
Everything works fine when I compile using the IBM JDK and Tomcat 3.2/4.0 on Intel
But that combination does not work on Solaris/Mac OS platforms, or on the Intel
platform when using JDK 1.3.1. The input values are simply lost. Everything else in
the application seems to work just fine. Just this problem with String [] parameters.
Does anyone know something about this issue?
thanks,
dave

Re: JavaMail Question
It's because of scripting security problems, discovered about 2 years ago: I don't remember the details, but cross-frames javascripts could lead the user to think his sessions expires and give his login et password again.

IllegalStateException and Tomcat 4.0
All of our forwardinghas broken when trying to run under Tomcat 4.0. Below issome example code causing us the problem - all of it works great under Tomcat 3.2! We have a small handful of JSPs which use... jsp:useBean id="sessionBean" scope="session" class="org.dlese.dpc.catalog.SessionBean"/ jsp:forward page="%= sessionBean.getCurrentPage() %" / whichnow returns a "Resource Not Found Error" andhave used jsp:useBean id="sessionBean" scope="session" class="org.dlese.dpc.catalog.SessionBean"/%String jspPage = sessionBean.getCurrentPage(); RequestDispatcher dispatcher = getServletContext().getRequestDispatcher(jspPage);dispatcher.forward(request, response);% ... which now throws IllegalStateException. Same thing happens when our serlvets forward using RequestDispatcher. I realize the exception is suppose to indicate thatsomething has been written to the response already or that the response buffer has been flushed, but we didn't change any code - nothing is being written before forwarding that I know of any help would be greatly appreciated.

Java Swing and XP data
I bought my new laptop for two reasons: 1. Keyboard stopped working (main reason) 2. My recent use of IntelliJ causes too much disk swapping InelliJ is a Java IDe and consumes a shitload of RAM. My Sony laptop never did much disk swapping because it had 256MB ram. That is, until I started using IntellJ. Whenever my laptop started doing disk swapping I would go to task manager and sure enough IntelliJ was using 50 to 100 MB of memory. So, I just said to my self that Java IDE's are all just memory pigs. After all JBuilder and Sun's Forte/NetBeans are even MORE memory hogs than IntelliJ. So when I got my XP Toshiba the only program that didn't work was Morpeus. And I can't live without that. So I started using LimeWire, a really cool Java Swing based Gnutella client. I really like LimeWire. It's much more polished than morpeus. However, after using it my disk swapping came back. Fuck! I have a brand new laptop with 512MB of RAM and it's freaking disk swapping. This pisses me off. Looking into task manager, I find LimeWire is almost as much of a memory hog as IntelliJ. So in short, my 512MB of RAM has gained me nothing for (i think) two reasons: 1. Forced to use limewire instead of morpheus. 2. XP is more of a memory hog than win2000 (i think i can turn shit off but i'm not sure) I am now pissed off that i spent all this time and money and still have excessive disk swapping. Here some questions I have: Does XP use more memory than win2000? Are LimeWire and IntelliJ poorly written applications or is Swing a memory hog? Something to think about if you'll be developing swing apps. === To unsubscribe: mailto [EMAIL PROTECTED] with body: signoff JSP-INTEREST.

WebLogic 6.0 and Mime Types
Hi, I want my wap users to be able to enter just my domain name, and get a welcome page. On Tomcat this works fine, I just have an index.jsp which outputs the WML. But when I use the same code on WebLogic I get 'Unsupported Content Type' returned by my browser. This is in spite of using the same web.xml in the WebLogic DefaultApp/Web-Inf as in Tomcat's Root/Web-Inf, and that web.xml containing all the mime types. Does anyone know how I fix this on WebLogic, or if its fixed in Release 6.1 ? Thanks Dave === To unsubscribe: mailto [EMAIL PROTECTED] with body: signoff JSP-INTEREST.

Re: Swing components in JSP
This is a permission issue for the X windows server. I expect the terminal is owned by somebody and the java process by another user.

Re: EJB and Tomcat/Servlet and JSP
After playing around with this for a while, I found that thest thing to do is to use Javabeans to do the dtabae access. I don't know why you would need an EJB, a simple JavaBean should be enough. I use one for selects and inserts to the database, then I can call it from JSP and servlets.

Secondly, I have another question, if I want to build a web application, mainly to access the database (delete/add/modify, etc). Should it be good enough if I put these codes inside servlets, in other words, use servlets to control the business logic as well as manipulate the database? Or do I need to write my own EJB(s) to do this database manipulations? My client will talk to the servlets, then the servlets will talk to EJB(s). perhaps it is a 4 tiers architecture. If that is the case, then I would need somthing like JBoss, which has Tomcat embeded so that it can serve as a single engine for both servlets/jsp and EJB all together.

Standar Template
I want to create a web app in which every page on the site has a standard header along the top and a standard menu along the left edge (a pretty standard thing). I came up with 2 ways of doing this: 1. Use a table tag and jsp:include tags on EVERY page: table tr tdjsp:include page=standardHeader.jsp//td /tr tr td colspan=2 table tr td valign=topjsp:include page=/menu.jsp //td td valign=top THIS IS WHERE THE PAGE-SPECIFIC CONTENT (i.e. the body)* /td /tr /table /td /tr /table 2. Invert the above solution to create one master template (or controller) and have the content page name passed in as a parameter. Here would be the master template-controller page: table tr tdjsp:include page=standardHeader.jsp//td /tr tr td colspan=2 table tr td valign=topjsp:include page=/menu.jsp //td td valign=top jsp:include page=%=request.getParameter(contentPage)% /* /td /tr /table /td /tr /table The key difference between these two architectures are best understood by looking at the 2 lines with the * at the end. Also, in option 2, there is only one copy of the above code. In option 1, there is one copy per content page Q1: Does anyone have any preference between options 1 and 2? Q2: Is there a better way of achieving this result? Q3: Do either have any negetive drawback I need to consider? (I will be converting an entire site) By the way, I'm currently achieving this effect VERY easily using good old client-side html frames. But due to popular demand, framse must go.

Was this the first request to the given JSP page? If the answer is yes, then Tomcat needs to translate your JSP code into a valid Servlet and then compile the servlet. The only time this occurs is the first request after the page has been modified - that is why it may take a while.

In comparison the PHP setup I have is almost instanting when I make a request for a simple page. Any thoughts on how to speed things up?

JSP Tomcat Windows 98
Hi, I've recently set up a tomcat server to test my application. I can get the servlets and HTML working, but I can't get any of the JSPs working. I've set it up on Windows NT and had no problems at all. What is the difference for the Windows 98 set up for JSPs ? Is there another parameter to set in Classpath or something ?

Re: Response has already been committed
Often this happens because you are attempting to forward a user to another page or an error has occured and Tomcat is attempting to send the user to your web apps error page and content has already been sent to the user. This can also happen when you try to set various headers in the response object (mime type, length, etc.) and content has already been sent to the user. Most JSP engines, including Tomcat, use a buffer that temporarily holds information to be sent back to the user, as long as the buffer has not been flushed (i.e. sent to the user's browser), you can do stuff like jsp:forward, etc. Once the buffer has been flushed at least once, any attempt to forward the user, set HTTP headers, etc. will cause the app to get this exception. The buffer is something like 4K or 8K in size. Double check the content on your page, you are probably getting an exception which is causing a forward to your error page, but the buffer has already flushed. Check the log files carefully, you might have an earlier exception that is being masked by the IllegalStateException. Many of the books on JSPs and servlets also cover this issue, so you might visit your local bookstore to scan for help on this issue.

JSP beans... blank results
I'm getting a strange result when trying to work with Beans and I'm hoping someone can point out what I'm doing wrong. I'm writing a simple test bean, one private string var and the constructor initializes that string. My jsp declares the bean, and then calls the getVariable() method that simply returns the value of the string. Fine, everything works. If I then even change *one small thing* in my code, it won't work any more. As in, I rename getVariable() to getFoo() recompile the code, save, upload the class file to my test environment. I then change my jsp to call getFoo(), upload that to the appropriate spot... and I see a blank screen in IE. Nothing, nada, not even anything in the source. It doesn't appear to be an ERROR, per se, but something is obviously wrong. Anyone have any ideas? I'm running on a JRun 2.x server, so the JSP has to be 0.91 syntax compliant. :P -dave === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Re: difference between variable declared using %! % and % %
Geert, You are listed as a contributor to the book Professional JSP, by Wrox Press. On page 32 of that book, it clearly describes %! % as enclosing a declaration block for variables and methods. The only fault I see in Surya's explanation below is not further explaining what is meant by "valid in the page scripting language," or explaining the scope of declarations in the block and the JSP relationship. Is it possible you are making reference to the concurrency problems when using the declaration scripting element in JSP vs. Servlets? Of course, the original inquiry from Kishor did not state whether he was using a Servlet. And then too, this becomes an implementation design issue as opposed to a simple functionality issue. Perhaps the book is in error. Please clarify what you mean by, "%! % is NOT meant to declare variables."

Re: JSP, JRun, and Beans
The problem is, getMessage has no arguments. It's a simple function that
returns a String type, takes no arguments and just returns the value of the
private String "message". so with bean
package ravage;
public class SimpleBean {
private String message = "No message specified";
public String getMessage() {
return(message);
}
public void setMessage(String message) {
this.message = message;
}
}
I have the corresponding jsp code trying to get it back out
jsp:useBean id="test" class="ravage.SimpleBean" /
%= test.getMessage() %
that's it. done. and it doesn't work. :( Any clues from that? I've stopped
trying to use the setMessage() procedure in the bean since I can't even make
the get work. thanks for help

One thing you might wanna check is the argument types of the method and
return
value if you are accessing it.
For ex if getMessage has a string argument and you calling it without the
argument you will get the method not found error
because the function declaration does not match the call.Check the scope of
the
method too.
The error isn't exactly "Method does not exist" , but "method
declaration does not match call" . The error message is not very descriptive
. I
have been through similar errors before , it may not necessarily be the same
in
your case, you can try it though

Subject: I am a beginner
Hello I got my java program to work if I type in java it works. If I type
in javac it work. But when I made a simple program like for a button on an
applet it says:
import java.applet.Applet;
import java.awt.*;
import java.awt.event.*;
public class clicker extends Applet implements ActionListener{
TextField text1;
Button button1;
public void init(){
text1 =new TextField(20);
add(text1);
button1 = new Button ("Click Here!");
add (button1);
button1.addActionListner(this);
}
public void actionPerformed(ActionEvent event){
String msg = new String ("Welcome to Java");
if( event.getSource() == button1){
text1.setText(msg);
}
}
}
There error says:
clicker.java:15: cannot resolve symbol
symbol : method addActionListner (clicker)
location: class java.awt.Button
butto1.addActionListner(this)
^
I Don't understand what that means I got this example out of a book "Java 2
Complete." Does this book suck?
If you know how to solve my problem can you help. And can you point me in
the right direction for book that I need to get.
Thank you

Re: De-Tokenizing ?!
wouldn't that never enter the "if" since you're initializing the string var
to "" and then only adding items to it if it's NOT already equal to ""?
sorry, I'm not a perl programmer, so maybe I'm interpreting it wrong... my
pseudo-code would be close to . . . .
myString = ""
for (x=0; xN; x++) {
if (x==0) {
myString = myString + myArray[x]
} else {
myString = myString + ", " + myArray[x]
}

Re: Can JavaScript access JavaBeans?
But that's not *really* accessing a bean from javascript. The server will
process the page first, replacing %=Password.getPassword()% with the
password value. It would look something like this after processing:
if(document.password.newpassword.value == "passwd")
When the javascript function is called, it only looks at the client-side
page. The difference is java is server-side, and javascript is client-side
(usually).

I'm relatively new to JSP and servlets and wish clarification on the binding between a session object and bean instance.

Re: Dynamic Forms
Dave,
If you name all of the checkboxes using the same name as below
input type="checkbox" name="mail_option" value="a"Send me mail/inputBR
input type="checkbox" name="mail_option" value="b"Send me mail/inputBR
input type="checkbox" name="mail_option" value="c"Send me mail/inputBR
input type="checkbox" name="mail_option" value="d"Send me mail/input
The JSP or Servlet that gets called will get all of the parameters as a
array of strings.
To read the data in a JSP or servlet use
String[] mail_option = request.getParameterValues("mail_option");
You'll receive a String array that has the value of each checkbox in a
different string.
Good luck.

Subject: Dynamic Forms
Hi,
We want to be able to retrieve a list of values from a form that
will have different quantities of elements per user. Specifically, we
have a form where each user can update/delete multiple email accounts
preferences. So something like this:
USER BOB:
[[EMAIL PROTECTED]]
XSend me mail on event 1
XSend me mail on event 2
[[EMAIL PROTECTED]]
XSend me mail on event 1
XSend me mail on event 2
The address would be in a textbox and the X's represent checkboxes. The
problem we face is uniquely naming each one of those form elements. We
would like to find a method better than incrementally naming each on of
the elements and then parsing a rather sizeable querystring afterwards
via looping. So, in short, are there any alternatives???
Thanks!

Re: SSL
I know it is possible for a web server to serve secure and insecure content on the same page. For example, the online site for my financial institution causes IE 5.5 to warn me that the site contains SSL and unsecure content. Some secure sites opt to do this mixed security model because they don't want the overhead of sending an image via HTTPS. So in short, I think you can do it. Your users may get weird security warnings from the browser due to the mixed content. If performance is an issue you might want to look into some of the hardware-based SSL accelerators on the market. Supposedly they are faster than software-based SSL.

Re: Constuctor overloading in Java Bean
The JSP page will always use the no argument constructor. If you need to
create a bean using a constructor with arguements then you will have to
use a scriptlet in the page.
IMO, a JavaBean should be able to be constructed with either constructor
since JavaBeans are required to have a no-argument constructor to allow
them to function with an IDE. Constructors with arguments should simply
be convenience methods that are functionally equivalent to using the
no-argument constructor and one or more setXXX() property calls.

Re: A Random Question
You can do it with servlets. You have to check the request headers to verify that the browser supports compressed pages (gzip) and then use Java gzip capability to compress the data for the output stream. Marty Hall's book on servlets and JSP has an example servlet that does this. I don't think it is possible to do this with a JSP page though a JSP container could implement this feature. The downsides to this approach is that the entire output stream has to be built in memory and then compressed prior to sending to the client. As a result the load on the server is higher. In a very busy site the cost of using compression might actually make the site slower than if the data was sent uncompressed.

The goal would be for the JSP author to be a higher-end HTML developer who shouldn't have to worry about maintaining the session, etc. The goal for JSP is also to be able to deal with other markup languages that HTML, such as XML. Finding all HTML references in the generated output and taking care of session encoding would defeat that goal. It's possible, however, to provide custom actions for all HTML elements that includes links to other resources (e.g. a, img, form) and let the custom action take care of the encoding. Some days ago, I've also raised the question on resin-interest as I also started to worry about it. I have to mention that I didn't think about it much, so the first reaction when I understand the behaviour was similar to Dave. The point is that it would be hard to parse all HTML code, just to find out where URL is and encode it - think about JavaScript code. It would also break JSP contract as it's not parseable language, but that's *only* HTML with some other language-specific (e.g. Java) parts. One suggestion is either make your own tags which could provide the functionality or use some template systems like Resin's XTP.

Subject: Replace " "
hi,
is there any method of the String class which will allow me to get rid of
the blank spaces in a string.
i tried Str.replace(' ', '') but jvm does not agree with the 2nd argument
saying incompatible type. Is there any direct method other than breaking the
string into substring and then concat() it. or if something that i can put
instead of ''.
thanks,
sumit.

Question about URL rewriting.
If I want my JSP pages to work in a situation where cookies are disabled and
the server is doing URL rewriting
do I have to use EncodeURL for all of my HREF (and perhaps IMG) tags in my
JSP page.
Example. Here is a JSP page that retrieves an image (stored in a database)
via a servlet and has hyperlinks
to other JSP pages. Note: I am using a servlet mapping to map a servlet to a
directory
The way you would expect to write this page is something like this.
IMG SRC="mediaservlet?mediaId=5000"BR
a href="page1.jsp"page1/aBR
a href="page2.jsp"page2/aBR
a href="page3.jsp"page3/aBR
If I want the page to work in a URL-rewriting mode do I have to do the
following?
IMG SRC="%= response.encodeURL("mediaservlet?mediaId=5000")%"BR
a href="%=response.encodeURL("page1.jsp")%"page1/aBR
a href="%=response.encodeURL("page2.jsp")%"page2/aBR
a href="%=response.encodeURL("page3.jsp")%"page3/aBR
What I'm basically looking for is some guidance on whether or not I need to
do option 2 all of the time to
maximize portability and survive cookie-disabled browsers.
If option 2 is what I should do, why doesn't JSP shield the HTML developer
from this? The goal would be for
the JSP author to be a higher-end HTML developer who shouldn't have to worry
about maintaining the
session, etc.

Re: Question about URL rewriting.
But, the servlet needs access to the Session so it can do things such as
validating that
the user is logged on and can see the content, etc.
So, by your answer can I assume that all hyperlinks in JSP pages have to use
EncodeURL to
successfully survive a browser with disabled cookies?

Re: Stress Testing your JSP Site
One approach to stress testing if you have a Model 2 (action classes and request dispatcher) site is to take advantage of the architecture of the app for testing purposes. For example, if you have a front component servlet that takes an HTTP request and turns it into an Action object for processing, you can build a custom test app that simply generates Action objects and fires them at your back-end processing. You might be able to test the back-end path (where the bulk of your code is) without worrying about the front-end. Not a perfect solution, but it might be a good start.

Best Authentication Approach
I have been debating the best way to authenticate users on our web app. The app is a Model 2 style servlet/jsp app with EJBs on the backend (AKA Java Blueprints). Our site has material that is graded for different levels of access. Our security needs are as follows. public access (Anonymous) Authenticated Access A Authenticated Access B Authenticated Access C Authenticated Access D Authenticated Access E Members of group B can see any public info and any info graded as A or B Members of group C can see public, A, B, or C info and so on... Think of the info as being classified (though it is not) as public, confidential, secret, top-secret, compartmented, etc. What is the best way to authenticate our web users? JNDI RDMBS (Oracle or SQL Anywhere) Other We would like the solution to be a single-sign-on solution and I have access to a copy of Netscape's Directory (LDAP) server (version 4.1) We have not yet chosen an EJB/Servlet/JSP container.

Opinions on best IDE for J2EE work
I am seeking opinions on the best IDE for J2EE work. I'm planning an app that uses JSP, Servlets, and EJB in a J2EE Blueprints sorta way. I've been using JBuilder 3 on Windows for a couple of years (3.5 is too slow). IDE's I'm considering JBuilder Visual Cafe Forte Netbeans Visual Age Target app servers are: J2EE SDK (reference implementation) JRun 3.0 from Allaire JBOSS (www.jboss.org) Weblogic 5.1 What IDE best supports the following features? 1) Team development 2) Creation of JAR, WAR, and EAR files that can be deployed 3) Object/Relational mapping capability. 4) Intuitive easy to use IDE features 5) Integration with version control. 6) Complete support for J2EE I'm not interested in starting a "religous" discussion on whose IDE is best. What I want to know is simply, which IDE works the best for the job.

Re: invoke excel/word from jsp/servlet
The easiest approach would be to see the JSP pages MIME type to text/plain and then have a JSP page that delivers the data in tab or comma delimited format. The problem is that the browser is simply going to show the text vs. offering to save it as a file. Another approach would be to purchase one of the Excel components such as Formula One which can be used on the server side to generate an Excel document. You servlet would use Formula One to generate the Excel file and then stream it to the end user with the Excel MIME type. Another approach would be to use a digitally-signed Java applet that lets you write the file to the end user's disk in whatever format you wanted.

Re: Good ASP book?
Actually I don't believe I am. I believe some people in this forum have experience with ASP. You might not but other people may have. Don't assume everybody is like you. Web Professionals consider all technologies in order to maximize their opportunities. Sure some people may have recently migrated to JSP 1.0 but that doesn't mean they cannot provide assistance WRT to ASP resources based on previous experience. Actually, I think you are. Some people may have experience with DNS, Sybase, Linux, cross-country skiing or gormet cooking, but that doesn't mean this is the right place to talk about those subjects. This list has enough traffic without bringing up ASP. 'Web Professionals' should not be surprised when they get chided for posting off-topic messages to a specific mailing list. This isn't an "us vs them" question and I'm not touted one technology over another and I'm intersted in getting references from those people who in the past have indicated that they are also knowledgable with _that_ other technology. In particularly references of similar quality to the better JSP books.

JDBC Connection Management
I have just spent the last day researching the topic of Database Connection
Management and connection pooling, and now realize, that there are too many
choices. I would like to summarize what I have learned and perhaps someone
can correct me where I'm wrong or add a comment.
Here are your choices:
1. Non-pooled:
a. One connection per request: In the service method you open a connection,
do your work, then close the connection.
b. One connection per servlet: Store the connection as an instance variable
of the servlet. Open it in the init method. Close it in the destroy method.
c. One connection per session: Open the connection when you create the
session. Close the connection in the session time out event:
HttpSessionBindingListener.valueUnbound(..)
d. One connection per web application: Store the connection in the
ServletContext.
e. One connection per web application: Store the connection as a public
global static variable.
2. Pooled:
a. One pool per servlet (Pool as static variable of servlet)
b. One pool per application (Store pool in ServletContext)
c. One pool per application (Store pool as singleton)
d. One pool per application (Store pool in jndi server)
It seems to me that 2d, is what Sun is recommending.
Once you have decided to go with a connection pool, you have some more
decisions to make.
1. Write the connection pool yourself (Fun for me, but not practical for
most of my clients)
2. Use a third party, stand-alone connection pool like DbConnectionBroker
3. Find a JDBC driver, that implements connection pooling (is anyone using
this?)
4. Use an app server that provides connection pooling (like Web Logic or
Orion)
The next consideration is the API for working with the pool. You choices
are:
1. Use a Proprietary API:
For example, DbConnectionBroker uses:
conn = myBroker.getConnection();
// do work with connection
myBroker.freeConnection(conn);
2. Use a standard API. Sun, has defined the "JDBC 2.0 Optional Package
Specification". This specification basically states that the API for using a
pooled connection is indistinguishable from using a normal connection (at
least to application developers). In other words, the standard API is
essentially, "NO API". For example, here is how one might retrieve a
"non-pooled" database connection:
Context ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("jdbc/nonPooled/MyDb");
conn = ds.getConnection();
// do work
conn.close();
And here is how one would retrieve a "pooled" database connection:
Context ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("jdbc/pooled/MyDb");
conn = ds.getConnection();
// do work
conn.close();
The only code difference is in the jndi lookup string. In the first example
getConnection() means: "Open a new connection to the database server". But
in the second example, getConnection() means, pull a connection from the
pool. Likewise, the meaning of conn.close() is also different.
So here is what I am using:
For some clients, I am using Orion App server, a fully J2EE compliant
Servlet and EJB server. Orion provides connection pooling, via a JNDI lookup
as shown above. So for these apps, I am using the Sun standard API for
pooling:
Context ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("jdbc/pooled/MyDb");
conn = ds.getConnection();
// do work
conn.close();
I think this gives me one pool, per web application, but I'm not sure.
Anyone else know? Is this Sun defined or vendor specific?
For some clients, I am using Apache tomcat (with mySql). For these apps, I'm
currently using DbConnectionBroker, stored in the ServletContext. This gives
me one pool per web application. What I would like to do, is use the
standard Java API's for these tomcat apps, but I can't find any stand-alone
connection pools that support the standard, java-defined API for connection
pooling. Anyone know of any?
So there is my take on the whole connection pool thing. Please let me know
if this sounds correct and where I'm wrong.
Thanks,
Dave Ford

PreparedStatement and Connection Pools
My understanding is that the benefit of a PreparedStatement is that you
"prepare it" ONCE and then "execute it" over and over. Thus, the server has
a chance to optimize complicated SQL statements ahead of time. So, based on
this reasoning, one might choose to "prepare" all of your statements in the
servlet's init() method. Then execute them in the servlet's service (or
doGet) method over and over.
My Question is, how does one receive this "prepare" benefit when using J2EE
style connection pooling? Here is my code:
try{
String SQL =
Context nCtx = new InitialContext();
DataSource ds = (DataSource)nCtx.lookup("jdbc/pooled/mysql_ss1");
conn = ds.getConnection();
ps = conn.prepareStatement(sql);
rs = ps.executeQuery();
/* use the ps here */
}
finally{
if(ps!=null) ps.close();
if(conn!=null) conn.close();//this really "releases" rather than "closes"
the connection
}
Since the scope of conn is local to the service method, and ps is connected
to conn, how can a ps ever live longer than the service method?
Thanks,
Dave Ford
P.S. Is it politically correct, to post to more than one newsgroup?

Re: JSP vs PHP
-JSP allows for the use of all the Java features including JDBC, integration with servlets, and full use of object oriented design and programming. I consider this the most important advantage of JSP over PHP. Obviously, PHP has some level of oop support, but it's pretty limited and gets frustrating after a while. Also, the standar JDBC interface is a *huge* plus in my book. -JSP's pure java support means that anyone who knows Java can code for JSP. There is no propriety language to learn. Java is well supported and documented. Training and books are easy to find. Employees are willing and eager to learn and use Java. It will be more difficult to find developers with PHP skills than JSP skills. Not sure I agree with this completely. While it's true that anyone who knows Java can code JSP, I don't know if I'd say it's not proprietary. I think the learning curve for PHP is not nearly as steep as it is for Java, and have found that non-programmers can actually be quite productive with it. I think it would actually be easier and cheaper to find developers who can pick up PHP. -JSP will allow for easy integration into an eventual Enterprise Java Beans architecture should company_name decide to scale operations with an application server. This is a major consideration. Excellent point. -JSP is widely supported across major web servers due to the popularity of Java. PHP, however is currently supported on Apache only: "The second, and most popular, method is to run PHP as a module in a multiprocess web server, which currently only includes Apache." -PHP FAQ 4.3 Actually, this isn't true. See http://uk.php.net/manual/install-windows95-nt.php If there's a need for scalable Enterprise-level systems, your first and third arguments speak for themselves. Also, if you ever need to integrate other technologies (ie wireless, XML, whatever), Java is the most flexible. And hey, there's no reason you can't use both. There are some things that might be overkill in Java which a simple PHP script can handle very easily, such as a contact-us form. Also, you might consider PHP as a good prototyping language. Just remember not to become too attached to the prototype ;-). And for whatever it's worth, check out babelj. http://www.twmacinta.com/software/babelj/ I've never actually used it, so I can't vouch for it, but it claims to integrate Java w PHP. === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

The 1.3 JVM with HotSpot could be a rocking engine for server-side Java, but this bug seriously hinders its use on NT. Please vote! Scott Stirling Allaire -Original Message- Date: May 26, 2000 06:05 AM Author: Dave ([EMAIL PROTECTED]) Hi folks, There is a bug in jdk1.3 (windows version) that prevents us from running JRun (and other java based server programs) as an NT service. At first it seems to work fine, but the jsm process is killed as soon as someone logs out from the desktop. It wont start up on a log in again. You need to reboot or start the service manually. This is a known and reported bug in the "Bug parade" at JDC. The problem is there with JRun, all service installers, rmiserver etc. Please log in at JDC and vote for this bug: http://developer.java.sun.com/developer/bugParade/bugs/4323062.html You might have to register, but it's free! Hopefully they will fix the bug if it gets enough votes and then we can use Windows NT as a java server environment again!? It works with jdk1.2.2 and others, but we want the speed of jdk1.3... /Dave === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Re: Handling of multiple requests for JSP and JavaBeans

Yes, class instances would be shared among all threads that are in the same VM. Now, with the inclusion of JavaBeans in the JSP you can set the scope to = session. This means that one instance of this JavaBean is dedicated to = the client for the session. Is this a full flegded java object with no = chance of conflicts between instances for different clients? Are there a = pool of the JavaBeans in the JSP engine/container? Yes, a bean you instantiate with session scope should never be seen by any other client except the one that originally caused it to be created. You pretty much have to trust your servlet engine to manage this correctly. ServletExec, for example, creates a random, 20-character session ID which uniquely identifies the client. The session ID is stored as a memory-resident cookie in the client. When you use the implicit "session" object in a JSP (or do req.getSession() in a servlet), the engine is responsible for giving you the proper session object. If I create another object from some Java class within the JavaBean, = will that cause any problems for me? Will there be any conflicts between = clients if I have class variables in this class? Will the JSP = engine/container instantiate an object for each request or will there be = some kind of pooling? There's no conflict as long as the new objects are instance variables and not class variables. If it's a class variable, then you would be sharing the object among all instances of the JavaBean. Not sure I understand the last part...the engine won't instantiate an object inside your bean - only your code will do that. But if your bean is session scope, then it will definitely not do it for each request. To really see what is going on, put a System.out.println() in each of your constructors. Hope that helps...Dave F. Thanks for any inputs, Roger Kjensrud === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Re: question about sessions
Since all request are coming from the same browser instance (even if different windows), there is only one session as far as the servlet knows. There's no way around that. Of course, using two different browsers would keep the sessions distinct (i.e., user opens IE, then opens Netscape). The thing I would suggest is to store a flag or something in the session immediately after a user has logged in. Then send an error back on any request that tries to log in while this flag is true. That should prevent multiple concurrent users. Dave F. Venkat Kethababoyina wrote: I have a simple registration servlet that uses session object to store the registration objects until the operation is completed. I am running in to problems when a user does the following: a) opens two browser windows from the *same* machine and tries to register two users simultaneously. Since our registration involves multiple pages, the user can finsh the first page of one account and then start the second page of the second and so on.. Essentially, the operations are interspersed. b) Now,if I use the session object to store registration info I am getting one user's data in place of another's. It looks like I am getting the same session object when I'm asking for request.getSession(). I would like to know if we get different sessions or same session in this scenario. If it is same session, is there a way to keep track of different user's data in the same session? Thanks for your suggestions. Venkat __ Do You Yahoo!? Send online invitations with Yahoo!
