Re: GURUS: is a session Array Bean possible?

2001-02-08 Thread Murphy, Chris (OTS-EDH) 

I solved the performance issue:
My search query was a "SELECT * from xxx where xxx like ? AND xxx like ? AND
xxx like ?, etc"

Since I am only interested in the record_id's, I changed it to "SELECT
account_id from xxx where ..."

The queries are lightning fast, now...

Subject: GURUS: is a session Array Bean possible?


Look at this piece of code from a JSP page:



This fails miserable, but you get my point... Is there another way to make
an array persistent throughout the session?

Let me explain: Right now, I have a query that returns 25 rows at a time.
The problem is performance:
Everytime the page is accessed, via the 'next' hyperlink (which contains a
parameter that keeps track of the range of rows to query) it re-performs the
original query because I can't figure out a way to return records 25 - 50,
51-75, through SQL.

[pass 1]
For example, I perform a search query that returns 5000 rows and then I
store the record_id's into an array called index. Since I want to see the
first 25 rows, I perform 25 individual queries with the record_id's
contained in index[0] through index[25] (this part seems like it would be my
bottleneck, but it isn't). Next, I create a hyperlink that hits this very
same page, but I pass it a variable named index_range=25.
[pass 2]
Same page, I perform that same query that returns 5000 rows and the I store
the record_id's again.  Now index_range says '26', I can perform 25 more
individual queries with the record_id's contained in index[26] through
index[50]. This results in the next 25 rows.
[pass n]
Same thing, except I check for conditions where there aren't exactly 25 more
records, etc.

The obvious solution is to perform the search query once, store the
record_id's into a session-persistent array, then continue to use the 'next'
hyperlink to keep track of where we are in the record_id index.  Then
browsing through the records would be lightning fast.

Re: Any views on the Java Web market in the US ???

2001-02-08 Thread Murphy, Chris (OTS-EDH) 

In my company, I showed them what I could do with JSP, and my project
sponsors are completely behind me and my team.

I believe its up to us (JSP developers) to simply show management how
quickly and cheaply* a JSP solution can be used in the enterprise as well as
small projects.


* If you use Tomcat, Notepad, Apache, Linux, you only have to pay for the
programmer's time, rather than all the infrastructure .Net will need.

This is probably because Resin allows the use of .jar files (Java
Application aRchive), whereas Tomcat adheres more strictly to the formal
servlet specifications which disallow the use of .jar files.

Instead or .jar files, you will need to use .war files (Web Application
aRchive).  Check out the Servlet Specification v2.2 for more info on .war
files.

Re: passing data between pages

2000-12-20 Thread Murphy, Chris (OTS-EDH) 

I normally don't.  I use the entry page to authenticate the
username/password and then just store the user's info, like name, last
logged on, access level in a bean.  I then code each page with this rule:
"if for some reason the user bean is null, then show an error message
instead of the normal page."

The user bean will be null if the username/password authentication scheme
fails *or* if the session becomes invalid (usually an automatic 15 minutes
timeout).

I've used this approach for 3 different web-app projects and it works great.

Re: Shopping cart

2000-11-01 Thread Murphy, Chris (OTS-EDH) 

Access is not strong enough to handle a bunch of simultaneous requests
because of its limited architecture.  Every time a user performs a query on
the database, no one else can do anything (just for a split second).  I have
experimented with connection pooling, and it does seem to help performance a
bit. In my tests, large queries (about 5000 rows) submitted by two clients
at the same time produced different results.  Doing the same test against
SQL server, MySQL or Postgres always yielded the same results for each
client.

I haven't used Access since.  If you have a linux box sitting around, get
mySQL or Postgres installed on them.  They are both free and there are
native JDBC drivers as well as ODBC drivers for each.

CM,

It sounds great if I can use Access database to store products info with jsp
as front end. I asked the question because I read somewhere that Access is
not a client/server capable database. The way I understood that was that if
I have a jsp user interface that retrieves information about products from
Access database, it will encounter problem when many users on the internet
are simultaneously try to see products which would be served from Access. I
am not so sure. I like to hear from any one on the subject. Thanks.

Re: Jsp to Servlet and ViceVersa

2000-10-31 Thread Murphy, Chris (OTS-EDH) 

Here's how you call a servlet from jsp.






You can make the form
action="http://mymachine:8080/jsp_app/servlet/Myservlet" from a regular html
page as well.

To make the servlet give information back to the referring page, called
test_page.jsp,  try this in the servlet code: (incomplete)

...
request.setAttribute("message", "A message from the servlet");
RequestDispatcher rd =
getServletContext().getRequestDispatcher("/test_page.jsp");
rd.forward(request, response);
...

To receive data from a servlet, your jsp page, test_page.jsp, needs code
like this:
...
<%
String message = (String)request.getAttribute("message");
%>
<%= message %>
...

Have fun...

Re: Shooping cart

2000-10-31 Thread Murphy, Chris (OTS-EDH) 

Here's how I did mine (I don't have SSL working, yet.)
1. Have a database that captures customer info and product info.
2. Pull your products from a database into jsp pages for display.
3. Use a session bean to remember the customer's shopping cart items, just
for the session.  This means that if the customer closes all of his browser
windows, the shopping cart will be empty.
4. When the customer is ready to checkout, then collect their customer info,
credit card, etc.  Save this info to new session beans.  So, if the customer
leaves the checkout sequence, they won't have to re-enter all of their
customer info.
5. Then, on the final order submit page, commit all session beans to
database and email the customer an invoice of their order.  Upon submission,
all session beans should be cleared.

Here it is:
http://www.techrev.net/salestitan/_catalog.jsp?store_id=1

This is not too fancy, but configurable in the administrator portion of my
web-app.

Hi all,
I'm just experimenting with Resin as a replacment servlet/JSP

try and run my login JSP, I get the following error:

com.caucho.jsp.JspParseException: /ITEU/html/studentlogin.jsp:5:
can't find property `thesession'

The relevent line of the JSP file is:


and the corresponding setThesession() method exists in the slogin
bean.  The odd thing is that this was working in Tomcat, but I was
never sure if the syntax that I used for the jsp:setProperty tag was
valid, even though it did seem to work :o).

Could someone clarify this for me?

Thanks,
Raj.

Resin classpath issues

2000-10-03 Thread Murphy, Chris (OTS-EDH) 

I am almost convinced that Resin (1.2b) is a much more robust jsp container
than Tomcat.  However, I am having trouble installing my web-app.  I
modified resin.conf like this: (I also tried different variations with '/' &
without the '/')


 
 
 
 


'salestracker' is in the default doc directory and it has its own
WEB-INF/classes subdirectories.

Here's the problem: My app isn't picking up my beans/servlets which probably
means there is some problem with the classpath.  As you see, I set the app
up according to the faq's.

Has anyone been able to create a new web-app under Resin? (not just copying
your classes into the default WEB-INF/classes directory.)

Re: how to pass security information

2000-08-21 Thread Murphy, Chris (OTS-EDH) 

Here's how I do it:

You can keep the userinfo handy via a bean.  For example, I pass in a
username and password from a regular html file and the ensuing jsp file will
validate the user. If valid, then load up a bean (mine is UserBean).

As long as you keep the scope="session", then the authenticated user will
travel to each jsp page.

Dear all,

Since I have to pass some security information from one jsp to another jsp.
how use get method now. People can see the information in the html source or
in query string.
How can I avoid the information to display?
Or make it impossible to view the html source?
Thank

Gary

Tomcat running on Solaris 8 (x86)

2000-08-14 Thread Murphy, Chris (OTS-EDH) 

O wise ones:

I have installed tomcat 3.1 on my Solaris 8 machine. When connecting to
http://mybox:8080 , I can run the servlet examples ok.  When I run the
NumberGuess, the harddrives on the server just spin and spin and spin.  I
telnet'd in and noticed that the drive space was being chewed up in the
../jakarta-tomcat/work directory. I had to kill the java process because it
had chewed over 120MB!

Here is what I have installed:
OS: Solaris 8 (intel)
JDK: Solaris VM (build Solaris_JDK_1.2.2_05a, native threads, sunwjit)
Tomcat: 3.1

While we're on the Solaris-Intel subject, has anyone compiled apache's
module:
mod_jserv.so ?  This allows you to dangle webapps right off of your website,
example:
http://myserver/webapp1

Thanks

Re: Free MSQLS Server JDBC driver

2000-08-10 Thread Murphy, Chris (OTS-EDH) 

I have downloaded, but not tried, something called "freetds".  Take a look
at this and see if it works for you.

Hi

Maybe you can't. In Sun's java site, only commercial solutions are
available for MS SQL JDBC, and none of them is free. We are
also curious if any freeware exists.
