perform search

2000-04-23 Thread friza taib

hello,

Can anybody give me an example, how to perform search.
i'm using jsp running on Ibm websphere and using DB2

The situation is like this:

I want to display the name from table registration_queue,
if there's no name, then perform a search which that will retrieve from
another queue table and display in the same page.

TQ in advance.

Well, not all Java implementations map Java threads to OS threads.  AFAIK
the JRockIt VM does a N-to-N mapping btw Java/OS threads, and Tower's static
compiler implements their own threading instead of using the OS's.  So, if
you're using anything other than the vanilla, "standard" Sun JDK, the
question should be routed to the vendor.

Re: Thread and JVM

2000-04-23 Thread Scott Stirling

TowerJ is an exception.  I guess they are implementing their own green threads
model?  I'd be interested to find out more about that.

IBM and Sun are the leading JVM vendors out there, especially when you include
the VM implementations of all others who have licensed the Sun source code and
produced production implementations for their platforms, e.g., HP, Compaq, SGI,
etc.  Anyone shipping a Sun-based production JVM (including IBM) is using a
native threads model by default, except Sun themselves in the case of Linux
(which is supposed to change in 1.3 or 1.4).

JSP & iPlanet 4.1

2000-04-23 Thread Gareth Jones

Hi,

I've been trying to get iPlanet 4.1 (to which I am new) to serve JSP
pages for a couple
of days now, without success. I have enabled servlets & JSP, and have
also installed a
JDK (version 1.2.2_05). I have set the JDK path in global settings to
point to the JDK
directory and have left the runtime libpath & runtime classpath blank,
to force the
use of defaults. Unfortunately, I'm still getting the following errors
... does anyone
have any tips, or any idea what I'm doing wrong (or not doing) ? Any
help would be
very much appreciated.

Hi guys,

I'm using Tomcat, and one of my JSPs got pretty big, and I'm getting this
error message. "Code of a method longer than 65535 bytes" Is there any way
to get around to it? Is there a way to increase this limit? Thanks.

Re: Servlets/JSP on Mac-Server?

2000-04-23 Thread David Mankin

When I was trying the same thing last September, JRun supported the
Macintosh (marginally), but their JSP 1.0 compiler did not run.
(This was prior to Allaire buying JRun.  I haven't seen any evidence
of Allaire being concerned about the Mac at all.)

The only answer I could find was to use JSP 0.92 which did work.  We
eventually switched to Linux for our JSP development and deployment.
(We were never intending to deploy on Mac, but we did want the
graphic designers to work with JSPs on their desktops.)

BTW The comments apply to classic Mac OS.  I have no experience with
MacOS X Server -- is that what you were talking about instead?

You don't say what happens, but a potential problem in your eaxmple is that you
specify an HTML page as the error page; it must be a JSP page in JSP 1.0/1.1,
see the JSP specification for details.

Diff. between HttpSession and

2000-04-23 Thread Howard Lee

Hi,

I'm new to JSP, and have a question about how I should go about doing a
session management. I'm used to creating a HttpSession object and do
putValue and getValue on it, and I've seen a JSP example that uses a java
bean to store and retrieve values. It seems to me that if I use  to a bean, this is pretty much what an HttpSession object
is. Am I right about this or I'm mistaken? Thanks.

Re:

If u insist, I can send, but I guess it'll only confuse u, as it's linked
with other files as well.

Simply taking, we have one file APD00_01.jsp, say. Inside that we have many
sections -- banner, top, left, etc. In these sections, we are including the
relevant jsp files.

Feel free to clarify your doubts, if any.

Subject:  Diff. between HttpSession and 


Hi,

I'm new to JSP, and have a question about how I should go about doing a
session management. I'm used to creating a HttpSession object and do
putValue and getValue on it, and I've seen a JSP example that uses a java
bean to store and retrieve values. It seems to me that if I use
 to a bean, this is pretty much what an HttpSession object
is. Am I right about this or I'm mistaken? Thanks.

Re: 64K limit

2000-04-23 Thread Howard Lee

Hi guys,

I got it working, so hopefully others who has a same problem can benefit
from this. David was kind enough to explain and also suggest that I should
try using  and here is his explanation. I couldn't get it to
run until I put flush="true" (thanks Arnab Acharya!) According to the JSP
Book, this is required because of current limitations in the underlying
servlet API. So hopefully others can benefit from my frustrating easter
afternoon. :)

Hi, Howard.  I haven't hit this limit yet, but I've been in fear of
it since I began developing JSPs.  As far as I know, the limit is a
hard limit set by the Java language.  We're using JRun, instead of
Tomcat, so I don't know if this advice will apply to you, but...

The one solution we've considered is switching from <%@ include %>
tags to  tags.  These tags perform the including at
runtime instead of compile time, so there's no bloat of the JSP.  (If
you have one enormous JSP file, consider breaking it up into parts
and jsp:include'ing them.)  There are several problems with this,
though, if you're not used to using the jsp:include tags.  The main
one is that, the included page is its own servlet instead of sharing
the same namespace as the parent page.  So local variables that you'd
declared in in your top servlet are not available to the included
servlets.  This means that you must switch to using beans and
properties to communicate things between the jsp pages.
