Re: help needed

[Shrisha Radhakrishna]

Try using a shared variable (say, a vector, hashtable or a map) instead of
doing a DB read every time.

JSP with weblogic 4.0.4

[Shrisha Radhakrishna]

Hi All,
    I am trying to use Tomcat's 
jasper.jar with weblogic 4.0.4 (since this version of weblogic doesn't support 
JSP).  When I start my weblogic server, I notice that jasper.jar has been 
loaded.  Also the init function of JspServlet.class is called when I try to 
access a .JSP file thru any browser.  But, then, it crashes  Here 
is what is says:

Re: JSP Issue

[Shrisha Radhakrishna]

Web Browser? Or, Web Server?  JSP is server side scripting.  The browser
just sees HTML tags.  So, in theory, all browsers support JSP.  Obviously, u
gotta have a server which supports JSP.  I found that WebLogic 4.5.1 (eval
version available for NT and UNIX) particularly good.  Also, SUN's own Java
Web Server is worth a shot.  Hope this helps

Regards,
Shrisha

Re: Help reqd on Personalization

[Shrisha Radhakrishna]

Cookie(s).  The easiest way out is to store everything (login, page layout
details, colors etc) in the cookie.  The problem with this approach is that
if the user clears his cookies (or, they are somehow lost), he has to redo
the customization.  Same problem if you (as a developer) want to change the
format of the cookie.

A more elegant solution would be to store only the login (or, some id) in
the cookie and the rest of the customization stuff in a DB.

Re: Providing Data Lookup

[Shrisha Radhakrishna]

Why don't you use a wizard sort of an interface? The first page merely
displays the primary key (drop-down) and a "Next" button.  Upon submission,
you can populate the remaining fields into HTML form elements in the next
page.  This way, you can avoid JavaScript (no bloated HTML).  A much cleaner
solution, I would think.

Re: Fixed! (Re: High powered help?

[Shrisha Radhakrishna]

Also, defining the cells' widths for the rows helps
**immensly**. This way, the browser doesn't have to do
a 'best fit' to calcualte the cell widths (When the
browser employs the 'best fit' method, it waits till
the last table row to calculate the individual cells'
widths).

Example: use  instead of just


Don't sweat abt. this issue for small tables ( < page
or 2).

Re: Where can I find samples of URL Rewriting ?

[Shrisha Radhakrishna]

If you use Session tracking with the Servlet API, it autmotically handles
browsers that don't accept cookies by resorting to URL rewriting.  You as a
programmer don't have to explicitly rewrite the URLs.  But, U do have to
encode the URL with session ID.  The way u do this is...

for redirect: response.encodeRedirectURL(url);
for get's and posts's: response.encodeURL(url);

Why don't you look at the Servlet API?

Re: Session testing question

[Shrisha Radhakrishna]

If u use the servlet API to track sessions, the server will resort to URL
rewriting when client cookies are disabled.  So, if use a session.putValue()
or session.getValue(), either cookies OR URL rewriting used @ the client
side.  Note that you have to encode ALL URLs for URL rewriting to work.  The
way you do it is:
response.encodeUrl(url_string) for POST and HTML A HREFs
response.encodeRedirectUrl(url_string) for all redirects...

To test if your web app works with URL rewriting, simply disable cookies and
check whether some sort of a session id is appended to all URLs.

Hope this helps,
Shrisha

Re: How to call a servlet from a JSP page ?

You can submit a form with an image link (no need of any JavaScript).

I have been using these kinds of submit buttons without any image maps.

Re: JSP Performance?

[Shrisha Radhakrishna]

JSP files are not compiled prior to each request.  They are compiled only @
the first request (or when the source code changes).

Re: session problem

[Shrisha Radhakrishna]

No, No!  Session IDs are not stored as hiddne form fields. If Cookies are
turned off the server will use URL rewriting successfuly if the following
two conditions are met:
1.  URL rewriting is "turned on" on the server (if this is an option)
2.  You use the servlet API for session tracking (.putValue() & .getValue())
and all your URLs are encoded with the session id (use encodeUrl and
encodeRedirectUrl)

JSP/Package problem

[Shrisha Radhakrishna]

Hi All,
I have a very strange/painful problem.  Ok, here I go.  I use Weblogic
4.5.1 to host my JSPs.  The compiler adds a "package jsp_servlet;" to all my
JSP's when they are converted into servlets.  So, in other words all my JSPs
are in jsp_servlet package.  Now, I want to instantiate a user-defined
class, say x, (that is not in ANY package) from within my servlet.  So, a
statement in my JSP would be something like:

x temp=new x();

The compiler throws a error that says jsp_servlet.x not found in import.
Obviously, its looking for x within the jsp_servlet package.  How do I
access the default package from within my servlet?

TIA,
Shrisha

Re: JSP/Package problem

[Shrisha Radhakrishna]

Hmmm.. I tried that too.  The compiler doesn't croak on the import
statement, but, it doesn't lile the statement where I call one of the
method's of the user-defined (unnamed package) class.
So, my question is: "Is there any way to instantiate and use a unnamed
package class in a named package class?"  I know that this is a fundamental
Java Question, rather than a JSP one.. So, sorry...

Thanks,
Shrisha

Re: Developing sites with JSP and HTML

[Shrisha Radhakrishna]

MS IIS 5.0 doesn't actually interpret .asp files that have no dynamic
content. It's as good as plain 'ol  HTML.  So, there's no overhead.  Not
true abt. JSPs, I guess.

Re: Developing sites with JSP and HTML

[Shrisha Radhakrishna]

It can be as simple as a flag against each .asp file.  The .asp file may be
looked at once by the asp engine, and, if no dynamic content is found all
subsequent requests won't go thru the asp engine.  Lemme see if I can
"stumble" upon the article (again).

Re: Developing sites with JSP and HTML

[Shrisha Radhakrishna]

Still, better (faster) than going through a servlet engine, don't u think
Imagine the JSP engine converting the .jsp to a .class only if scriplets are
found.  This is eseentially what IIS does (and, that's good).

Re: Developing sites with JSP and HTML

[Shrisha Radhakrishna]

Yes, it just *looks* for ASP code.  It doesn't interpret (which is the topic
of interest here, isn't it?) and then figure out that it's just static HTML.

Hi All,
Anybody faced a problem in creating persistent cookies?  IE seems to
keep the cookie, but, netscape kills the cookie upon exit.

Here is how I set the cookie:
Cookie UserCookie=3Dnew Cookie("LoginID",name);
UserCookie.setPath("/");
UserCookie.setMaxAge(Integer.MAX_VALUE);
res.addCookie(UserCookie);

TIA,
Shrisha

Ok, I figured it out.  Netscape doesn't like INTEGER.MAX_VALUE.  I put in

This should definitely invoke the controller servlet with all the right

Re: need help on setting cookies to a URL object

Did you try "http://www.myvideoshare.com/members/join/index.asp"?
Also, the .asp file might be setting a dummy cookie and reading it back to
see if the client is cookie enabled.  Note that this is not a static HTML

Re: Passing spaces in query strings

[Shrisha Radhakrishna]

Hmmm.. I am not quite sure abt this.  Its perfectly valid for parameters to
contain spaces.  Do not use URLEncoder.encode() on the whole URL.. Here's
what I fo and it works beautifuly

<%String temp_url="servlet/SetCustomerForSession?cust_id=" +
URLEncoder.encode(cust_info) + "&redirect=" + redirect;%>

Re: bug with array casting within a JSP process

[Shrisha Radhakrishna]

Here is the answer!  You are trying to instantiate a custom class that is
not inside any package from within a .java that is inside a package.  When
your JSP is translated into a java file, the compiler automatically puts it
in a package.  (in weblogic, it is jsp_package;).
