How to implement content caching for jsp page ?

Hello everyone,
I am reading an article <Servlets and Jsp Best Practice>,at
http://developer.java.sun.com/developer/technicalArticles/javaserverpages/servlets_jsp/#author, on one section it is saying :
"Cache content: You should never dynamically regenerate content that doesn't
change between requests. You can cache content on the client-side, proxy-
side,or server-side. "
Now I am working on a project. For every user, some of the content servlet generated will be the same for at least a week . I am thinking if I implement caching for these jsp pages, that would increase performace a lot.
But I have no idea how to implement it either client-side or server-side, can someone give me a hint ?
Thanks,
Rachel

You mean actually you are caching the response stream
and the key to distinguish between different response
streams are made of user's different request
parameters. And the filter's function is to intercept
the request to see if this request parameter's
combination already exists in the Hashmap,then either
use the cached response or forward to
servlet.....really interesting...Do I get it right ?Yes that's it in a nutshell.
>
Then how do you build those response streams in
advance ? You did it manually or have some mechanism
to build it automatically ?
The data gets cached the first time somebody visits the page.
Find some examples on Filters, and take a look at the HttpServletResponseWrapper class. You need to cache response headers as well as the body. Another pitfall that you might run into is handling an If-modified-since header on the request. Don't cache the results of those requests.

Print version for JSP pages

Hi,
I have the following requirement. I have a site consisting of JSP pages. I need to provide a print version for every page.
The problem is, while printing, if a webpage spans for multiple printing pages, I need to put a footer on each of these pages. But, this footer must appear only once (at the bottom of the page).
How do I achieve this? any help will be greatly appreciated.

there is one work around for doing this... in order to print the header and footer...generate a dummy page with the exact format...
Header
20-25 Lines Text
Footer
Header
20-25 Lines Text
Footer
and so on...
so when this is flushed to the printer....u would get every page formatted with Header and Footer as this is going to happen in the background...there willl be no pblm to users...
hope this helps u...

Slow response time for JSP pages under iAS 6.0 SP4

Hi,
I got an application deployed on iplanet app server 6.0 SP4 on solaris
2.8. Using a single kjs engine and lite sessions. kjs memory size is
min 256 and max 256 megs. but verbose:gc shows memory is 98% free.
when i restart the app server, all JSP pages are really rendered fast.
After a while (1 or 2 days), the time to service the same request to
JSP pages is getting much longer (even with JSP pages having only
static content in them). CPU is idle ... It just takes time. KXS log
shows requet is taking like 2-4 seconds instead of about 150 milli
secs when the engine is just restarted.
Now if i call a servlet (which do not dispath to a JSP), the response
time is ok! Memory is ok. It looks like its related to JSP pages
only.
Anyone having an idea what the problem could be? One conig param is
the JSP page cache in iASAT. Default value is 10. What is a correct
setting for production? I have 4 different web app deployed in the
same server instance.
Tanks a lot for your input
Andre Paradis

Andre,
I have found the answer to my problem and perhaps yours. It seems that I18N (internationalization) in SP4 may have a performance bug in it.
My soak tests show that with i18N checked in the iAS Admin Tool, testing the fortune cookie sample application with light load (1 request / sec) resulted in a kxs response time initially of 15ms, however this response time increased by roughly 1% per request (i.e after 100 requests the response time had more than doubled).
Switching I18N off yielded a steady 7ms kxs response time from the fortune cookie application.
I would add that I turned I18N on AFTER the installation procedure.
Is this a known issue in SP4? Is there a patch?
regards,
Owen

Can't find Design View for JSP page on Unix

I'm using weblogic workshop to develop page flow on Solaris, and I can't find the Design View tab to build
JSP page. I searched all menus and can't find one to enable this function. Is this function supported on Unix?
Thanks

Zhong--
Unfortunately, no; Workshop 8.x does not support design view on UNIX.

Session-scope variable for JSP page used in a frame

Hi,
I don't know if there's a way to do this at the same time:
(1)- assign session scope to a variable (in order to be able to retrieve recurrently the previous value each time the JSP is called);
(2)- set its visibility in a way that it could be accessed only by the page that defines it. The JSP is used in a frameset along with an other JSP that can potentially define identical session-scoped variable (You understand why I want to keep them separate)
session.setAttribute():
seems not to be the thing I need
pageContext.setAttribute():
with SESSION_SCOPE, it behaves the same way as session.setAttribute(). with PAGE_SCOPE, condition (1) can't be satisfied.
Does anybody have an idea ?
Thanx in advance.

I can see that you will not want to maintain two different files for every possible page on the site!
It may be possible to do something like <frameset rows="*" cols="50%,*">
<frame name="content1" src="file.jsp?frame=one" >
<frame name="content2" src="file.jsp?frame=two" >
</frameset>and then in the jsp<%
String frame=request.getParameter("frame");
session.setAttribute(frame+"AttributeName",attributeValue);
%>This will set up two session attributes - "oneAttributeName" and "twoAttributeName". Depending on how many variables you have, this may prove just as difficult to maintain.
You may end up having to simply pass url parameters between pages to maintain state within the individual frames, which is far from elegant also.
I am interested in how you end up solving this one.

Cannot use jstl tag for jsp page which generated from Human Task

Hi
Plz help me.
I have tried to using jstl in jsp which generate from Human Task and I deploy it to server( by ant on Jdev ) to see task detail in Oracle Worklist application. But when i submit task and then I access to worklist to see task detail, the error has show in page that "OracleJSP: An error occurred. Consult your application/system administrator for support. Programmers should consider setting the init-param debug_mode to "true" to see the complete exception message. " .
I access server to see application.log to see error and I see error show "workflowform: JspServlet: unable to dispatch to requested page: Exception:oracle.jsp.parse.JspParseException: /Header1.jsp: Line # 3, <%@ taglib uri="http://java.sun.com/jstl/core_rt" prefix="c"%> "
How do I fix this error?
PS. I tried to us jstl because I need to connet to database which jstl tag(sql) if somebody has another solution for connect database in task detail page, Please help suggest me.
Thanks
user520932

Is the jstl tag libray loaded in the appsserver?
Can you use jdbc connection like
DataSource ds = ic.lookup("java:comp/env/jdbc/myDB");
Connection con = ds.getConnection();
DataSource ds = (DataSource) org.apache.derby.jdbc.ClientDataSource()
ds.setPort(1521);
ds.setHost("localhost");
ds.setUser("APP")
ds.setPassword("APP");
Connection con = ds.getConnection();

Where can I find an official online documentation for JSP?

I'd like a JSP documentation like the one PHP has. Does JSP official online documentation exist? if so, what's the link?

What exactly do you need to know? JSP is just a bridge between HTML and Java. All you need to know is, yes, HTML and Java.
Here at Sun.com you can find API documentation of the standard Java SDK.
Java SE SDK API: http://java.sun.com/j2se/1.5.0/docs/api/
Java EE SDK API: http://java.sun.com/javaee/5/docs/api/
If you want to know about the taglibs, e.g. JSTL, here it is:
JSTL 1.1 TLDDOC: http://java.sun.com/products/jsp/jstl/1.1/docs/tlddocs/

Screen resolution for jsp page

Hai i have a doubt in the screen resolution of my page. i m using the screen resolution of my pc as 1024*762 pixels. i have done a jsp web page page in this resolution.while copying the page and running it in my friends room it appears differently because he s using the resolution as 1152*864 . Its there any way to solving the problem of viewing the page similarly in any kind of resolution...

Well it is not addressed by JSP rather it can only be done @the client end and javascript is what which can help you.
how is that its gonna do that,pls find the details by refering to the below link.

Security logic for JSP pages

I am developing a product using JSP and servlet. I want to know if any algorithm is there to prevent software piracy

Bad news: There is no such algorithm.
Good news: You don't need one.
Servlets and JSP are executed on the server so a user only gets plain html code. He actually has to hack your web server. Apply the usual measures (firewall, demilitarized zone and so on).
If you are talking about distributing your application to web service providers. You can use Obfuscators (like Zelix KlassMaster Java Obfuscator, CodeShield Java Byte Code Obfuscator , RetroGuard Java Obfuscator, ...) and build an online activation registration into your code (or any other licence mechanism).

Sytax highlighiting for Jsp Dyn Pages for portal development.

Hey,
I am doing JSP with the htmlb taglib for portals. When I edit a jsp page in the Developer Studio, I expect syntax highlighting. This is what I see in the documentation for jsp editing as well - you know where the keywords are highlighted.
Sytax highlighiting for jsp in Developer Studio for portal development.
http://help.sap.com/saphelp_nw04s/helpdata/en/ce/e0a341354ca309e10000000a155106/content.htm
OutputSuccess.jsp, OutputSuccessText.jsp are the two jsp's that are syntax highlighted on this page.
In my Developer Studio this is not the case. Is a JSP editor and its highlighting not part of the Developer Studio. If it is, how do I get it to work.
I also know that given the right taglib's, the editor also gives autocomplete for taglibs with its settings. I am hoping to speed up my development with this.
Right now I am using a text editor for this. There are a couple of jsp plugin's such as Exadel or Lomboz which I can integrate if a jsp syntax editor is not there in the Developer Studio. I just wanted to know the right way to go about this.
Thank you for your help.
Sumit.

Never mind. I was in the preview mode.
