Re: Use of Vector
Vikramjit, The reason that Vector is Synchronized is the main reason why I would use it in a web application... I dont want adhoc volatile values to be present.. Snehal, Could u explain what do u mean by Master Value... do u mean for ex.. of populating drop down lists, a list that is common across users and sessions. like an Application level data... if so then yes i would use a Synchronized Collection object, Vector works inplictly as a Synchronized Object, but if u want to use another class then I would recomend using the Synchroinzation technique in the Collections class so as to maintain data itegrity.

You could use other Collection classes or check the List interface. My 2 cents: For inserting the values use LinkedList (since LinkedList is faster for insert operations). LinkedList provides sequential access, additions and deletions, at a cost of slower random access. For retrieving or reading the values use ArrayList (ArrayList is faster for read operations). For instance, if your program is to frequently provide random access to the data of the list, (for example, "show me item three, twelve, two, and twenty-five") the ArrayList class offers quick access to individual elements of the list. When working with ArrayList and LinkedList, there are two ways of creating the objects: List cityList = new ArrayList(); LinkedList peopleList = new LinkedList(); The above creation ensures that, line 1 that we are creating an ArrayList but we are gonna use it as a List. While line 2 that, we are gonna use a linked list as a LinkedList :). > Thanks for help, > > Snehal Vikram. > > == > = > To unsubscribe: mailto [EMAIL PROTECTED] with body: > "signoff JSP-INTEREST". > For digest: mailto [EMAIL PROTECTED] with body: "set > JSP-INTEREST DIGEST". > Some relevant FAQs on JSP/Servlets can be found at: > > http://archives.java.sun.com/jsp-interest.html > http://java.sun.com/products/jsp/faq.html > http://www.esperanto.org.nz/jsp/jspfaq.jsp > http://www.jguru.com/faq/index.jsp > http://www.jspinsider.com > Disclaimer: This e-mail message along with any attachments is intended only for the addressee and may contain confidential and privileged information of GTL Limited.

Re: Query takes 10 minutes...I need to display some output...how?
from a jsp you can do out.println("Some text"); then follow with
out.flush(); to push the information in the buffer to the browser. This
usually works but I have seen some app servers still wait till the page is
finished processing

Besides flushing the buffer, in IE that won't work in table rows, you must
have already displayed the . Basically you have to do multiple
tables instead of individual rows.

Re: java.lang.OutOfMemoryError
It is not always a memory leak that causes "OutOfMemoryError". A memory leak is a situation when some application, for example JVM allocates some amount of memory and then loses pointers to that area. So, the allocated area becomes a "black box" which you can not access and you need a key to open it. It is very rare situation when some Java code causes memory leaks. They are reported and can be found at "Bug parade" on SUN's web site. "OutOfMemoryError" often caused by bad design. It can be for example: 1. Your program trying to process too much data. Increase the amount of memory or decrease the amount of data to be processed. Actually you can do it in a wise way: control how much memory left and if it less than, let say 20 %, decrease the processing speed. It was described in one of our tips while ago... 2. Your program holding too many objects and then program is running out of memory. You need to use close methods if you do need them. You can even explicitly set a reference to null to speed up garbage collection. 3. You use too many objects with finalizers... They consume your memory before you get any chance to run them... But most of the times, i have come to conclusion, its due to bad designing of applications which further coz memory leaks. Keeping the other factors in mind can help you solve ur problem. > -Original Message- > From: Daniel [mailto:[EMAIL PROTECTED]] > Sent: Friday, January 03, 2003 11:37 AM > To: [EMAIL PROTECTED] > Subject: java.lang.OutOfMemoryError > > > Hi I am getting this error in tomcat. > > What should I do to get rid of this? > > > > ERROR!: > ** > Message: java.lang.OutOfMemoryError > Attributes: > javax.servlet.error.servlet_name=jsp > javax.servlet.error.exception=javax.servlet.ServletException > javax.servlet.error.request_uri=/mori/jsp/events/view/viewAll.jsp > javax.servlet.error.status_code=500 > javax.servlet.error.exception_type=class > javax.servlet.ServletException > javax.servlet.jsp.jspException=java.lang.OutOfMemoryError > null > java.lang.OutOfMemoryError > > == > = > To unsubscribe: mailto [EMAIL PROTECTED] with body: > "signoff JSP-INTEREST". > For digest: mailto [EMAIL PROTECTED] with body: "set > JSP-INTEREST DIGEST". > Some relevant FAQs on JSP/Servlets can be found at: > > http://archives.java.sun.com/jsp-interest.html > http://java.sun.com/products/jsp/faq.html > http://www.esperanto.org.nz/jsp/jspfaq.jsp > http://www.jguru.com/faq/index.jsp > http://www.jspinsider.com > Disclaimer: This e-mail message along with any attachments is intended only for the addressee and may contain confidential and privileged information of GTL Limited.

Re: Query takes 10 minutes...I need to display some output...how?
This question crops up every so often. My best answer is still to treat the request as a batch request, i.e. program design. Simply initiate the request, and provide a link to fetch the data when it becomes available. (email is always an option as well.) Holding an http connection for 10 miniues introduces problems, and any failures might cause the user to post multiple queries, each one often needing to complete before being aborted. Frank Mancini wrote: I have a jap page that takes about 10 minutes to runthat is ok...it should take that long.. My problem is that I want to display some of the output while the user is waiting. I'm doing document.writes as I'm running the query and it should display, but the browser seems to wait until the whole 10 minute process is done before displaying anythingIs there anyway to change this and display some of the query output while the system is looping thru my query? _ The new MSN 8 is here: Try it free* for 2 months http://join.msn.com/?page=dept/dialup === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Re: JSP Exception
Hi Karthik,
Here is a link with some info :
http://www.websina.com/bugzero/faq/exception-db2-tab.html
Q: What is this COM.ibm.db2.jdbc.DB2Exception?
[IBM][JDBC Driver] CLI0637E QUERY cannot be found
A: This is a known bug in the JDBC driver in DB2 PF5, it occurs when a SQL
statement contains TAB or new-line characters. You need upgrade the
JDBC driver.

Ritesh
