driver prob
Hi Gurus, I had posted the query earlier but did not get any response , hope i get it this time Can anybody suggest me what oracle JDBC driver to use in order to coonect as a thin client to the oracle adata base. The problem is that when i am calling the function getImportedkey(...) of the DatabaseMetaData class it's returns null value even though the table has foreign keys . Bsaically i am trying to obtain the list of foreign keys present in a table. At present i am using the , jswdk, oracle 8i, thin client driver (classes 11.zip). Hope to get a quick response . regards Prasanjeet - Original Message - From: "Mathew, Binoy (CORP, GEITC)" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, January 22, 2001 12:23 PM Subject: Re: Session Variable > Hi, > Session variables are meant to store user profiles and data needed to > identify a user and his preferences, obviously if one fetches data from a > database and stores it in the session, this will not only clog up the > session variable but only defeat the very purpose of a database.

Re: Session Variable
Hi Ritu When we say Session it means all the information you are storing will be on server and on the client side you will have the ID of that session. if u try storing every thing in session then the performance will come down and server will run out of memory.This may some time crash the server if number of users are more..So better change the design of the report so that u will get more information on querying for the first time, instead of moving backward or forward. Hope this will help u.

Hi, Session variables are meant to store user profiles and data needed to identify a user and his preferences, obviously if one fetches data from a database and stores it in the session, this will not only clog up the session variable but only defeat the very purpose of a database.

Question about web-app paths (relative/absolute) and the use of multiple web-apps..
Hi all, I am still confused on an issue with relative and absolute paths when dealing with Servlet 2.2 .war paths. For example, in one applicatoin I deploy only a single web-app, and in my paths, such as I know this is a relative path to the root web-app. However, when two or more apps are deployed, I have noticed that if I don't specify the specific context of the web-app, things get a little messed up. Assume I deploy two apps, AppA, and AppB. Both apps I have the web.xml mapp the extension .do to a specific controller servlet. I am following the MVC architecture where by all requests to the .do extension get sent to the ControllerServlet, which then (by using a framework like Struts) calls upon an action class, then forwards to a JSP page. So, in either app, if I use links such as it seems to get confused..how I am not sure. If I use where contextPath is set to the app context name (for example, AppA/path/page.jsp) it seems to work alright. There is one particular problem that may be the culprit but I am not sure. I have a need to use 3 different web-apps (specifically to guarantee that each app has its own memory so no cross-talk can occur) but all 3 point to the same one war folder. This is because we have three identical sites in functionality, but are different in one way, the particular media type the user is logged in to. We do store a mediatype value for each user, but we used to get some cross-talk when they went from one media type to another, and I think it was mostly related to browser caching problems and the back button issue. So I am not sure if this is the problem or not, and the only thing I can think of is to always append the mediatype to every link and form url being submitted, such as using url rewriting. Anyways..if anyone can shed light on the how tos of multiple web-app deployments in the same server, possibly with 2 or more pointing to the same www structure, I sure would appreciate being set straight on this. Thanks. === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST". For digest: mailto [EMAIL PROTECTED] with body: "set JSP-INTEREST DIGEST".

Session Variable
Hi All, Can anybody suggest what all difference does it make fetch data once from the database and store it in the session variable, rather fetching every time from the database. for example in case of any report showing data in the form of Previous and next. is it better once fetch all data and store them into session variable or fire a query for fetching data on every click of previous and next.

Re: Fetching Data from Bean
hi puneet,
suppose if you use the bean in your architecture then the best way i
would say is , have the java class which is equavalent to the
resultset (or the table) and transfer the object into the jsp page
and use its methods to show values in the page.
for example ,say you have to display the employee details in the page ,
have the 'employee object' , construct the same in the bean with the
result set values.write the method in the bean which returns the employee
object ..
...
public Employee getEmployeeDetails()
{
return employee; //contains the values from the result set
}
then in the JSP page,
<%
Employee employee = null;
employee = emplyeeBean.getEmployeeDetails() %>
then,
<%= employee.getName( ) %>
hope this helps,
regds,
rathna.

Re: Fetching Data from Bean
Thanks for the suggestion but i don't think this is an adequate way of
writing JSP. For an enterprise wide solution, it's not a proper approach to
write db access mechanism embedded in web pages.
Ok my real question, is how to pass a resultset back to JSP from a bean ? I
don't want to return back the resultset object even as for a thumb rule that
front end should never know about data access.
How can i convert say a resultset to a 2-dimension array or vector of
vectors or any other methodology for tranferring data back to web page.
Is there any sample application available on web that can be used a model
for writing the JSP applications, ie. following n-tier architecture.
Thanks very much

Re: Stop posting off-topic questions
I am not aware of a Java specific mailing list. JSP, Servlets, XML maybe, but not JAVA specific questions, otherwise I would be happy to ask questions there too. However, there are probably several hundred, if not thousand developers that subscribe to this list and we all have varying degrees of knowledge. While I agree that JSP should be the focus, there are many of us using JSP in our applications and may need help on instituting a bit of java that we are not familiar with. I do hate to see all the "out of office" replies, and advertisements, and so on. But JSP mostly, with some intermixed java related questions should not be frowned on. Some of these people may know a lot more than others and just may not have found the answer they are looking for elsewhere. I for one enjoy helping out as much as I can, because I do ask alot of questions too. Oh well..I agree with the other reply you got, you can't do anything about it, and frankly anyone can ignore your post, or any other post, if they want. > -Original Message- > From: A mailing list about Java Server Pages specification and reference > [mailto:[EMAIL PROTECTED]]On Behalf Of Panos Konstantinidis > Sent: Monday, January 15, 2001 3:55 AM > To: [EMAIL PROTECTED] > Subject: Stop posting off-topic questions > > > No, I do not want to answer this question HERE.

Re: Any Java based zip finder or distance between 2 zip codes?
It may not be a JSP related question, but I am using JSP for the pages that will interface with such a solution. And, while you may think there is not, you are but one tiny person in this oh so great world of ours, so I doubt your great wisdom of java will surely be the final answer as to whether or not there is indeed an api written in java that does such a task. As a very regular contributor to this mailing list I seldom ask off-topic questions and while I did not specifically state that I would be using JSP, nor ask a specific JSP technology question, there are a large number of developers in this list that do things other than JSP. Therefore, while I generally stick to the JSP related stuff, every now and again I feel compelled to ask others that may be using JSP and other similar technologies for advise or possible info on something I can't figure out in the immediate short term. Feel free to ask some questions..I'll be happy to answer whatever I can. > > This is NOT a JSP-related question.

Re: Stop posting off-topic questions
Asking ASP/NT in JSP channel really got my nerve. But think about it... Those ASP developers can't even get help from Microsoft support, and have to beg, on their knee, in enemy channel for help. Can they be more pathetic? Should we show our empathy to them? In the future, the standard answer to such questions would be: USE JSP YOU MORON Just my two bits. P.S. But I always welcome all questions in switching ASP to JSP. > No, I do not want to answer this question HERE.

Even though the files are uploaded properly when i include the files its showing the contents of the old files. I think the file content is cached in the JVM. How can i clear the cache once the files are uploaded ??? I can solve this problem be restarting the serverbut i cannot do this everytime the files are uploaded...so any suggestions ?? regards G.

Any Java based zip finder or distance between 2 zip codes?
Hi there, Anyone know of a java api or library that works with a database of zips so that all zips from a distance of x miles from a given zip can be retrieved, or the distance between two zips can be retrieved? Also would like to see it return the state, city, area code, population info. Thanks. === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Closing a DB connection used in a bean
I've a bean. It's constructor open a connection to a db using jdbc.
Each jsp page which needs to access the db, has this line:
I need to close the connection to the db when the user close his browser, so
i'd write something like this in each page:
<%! public void jspDestroy() {
db.closeConnection();
}
%>
But it doesn't work because the "db" bean is not recognized inside the
method.
Any tips?
