 Subject:  vector cast to int

 i'm trying to do an explicit cast from vector object to int..

 if you look at the below stripped out code, where tempTotal is defined,
 that
 (int) conversion doesnt work..

 ultimately i'm trying to perform a division computation w/ totalVotes.
 anyone have a solution???

 
 java.sql.ResultSet regularPoll = null;
 try {
   regularPoll = db.execSQL( select votecount from sometable where
 id=someid);
 } catch (SQLException e) {
 System.err.println(e.toString());
 }
 Vector pollVotecount = new Vector();
 while(regularPoll.next()) {
pollVotecount.addElement(regularPoll.getString(votecount));
 }
 int totalNum = 100;
 int tempTotal = (int) pollVotecount.elementAt(i);
 int tempNum = tempTotal / totalVotes);

 Subject:  Urgent  Please help me

 Hi,

 My JSP contains the following things

 A text box
 and a GO button which fetches the result based on the criteria entered in
 textbox.

 The GO button has a validation for a blank search criteria and displayes
 alert
 message if we press GO without entering anything.

 But the problem is, if I hit on ENTER, it fetches me the result even if I
 haven't entered anything in the text box. It does not go through the
 validation which executes on pressing on GO button.

 Please help...

2001-11-17 Thread Gochwal Meenu 

 We have two list boxes..list box 1 contains all the data from the system.
 On click of the button whatever data is selected from the list box 1 it
 moves to the list box 2. The data in the list box 1 is such that it also
 contains related data uptil n level of hierarchy displayed in the list box
 1 only.
 Our problem is if we select a data from the list box 1 , all its related
 data till n level of hierarchy should move to list box 2.

 E.g data in list box one is

 Data  Related Data
 A -
 B A
 C A
 D B
 E A

 Now if I want to move A then B,C, D, and E should also move to list box 2
 even if they are not selected.

Re: Limiting number of records returned to be displayed

2001-11-14 Thread Gochwal Meenu 

Hi

You can store the records in the resultSet n put that resultset in the
session.
on the click of the next button forward the jsp to the same one n pass a
parameter which keeps on incrementing on the click of the button.
Now for displaying a particular row use rs.absolute(int row)

Re: Tomcat: jsp : JDBC ORACLE

2001-11-04 Thread Gochwal Meenu 

There is some error in ur code
Use it this way
l_Stmt.registerOutParameter(1,Types.INTEGER);
  l_Stmt.execute();
   int l_Return = l_Stmt.getInt(1);
 now check what l_Return returns

What i mean to say was that instead of using this stored procedure
use addBatch(String sql).In this pass the query which is to be executed.
Then use updateBatch() which returns u the int[] array i.e the no of rows
that where updated/inserted

 Subject:  Populate Struts' Action Form Bean's Date field by a String
 input

 Hi

 I have a form bean with a Date field with accessor  and mutators
 `Date getCurrentDate()' , `void setCurrentDate( Date )' ?

 I have written a custom subclass of the html:text to do the following

 pp:text property=currentDate  trim=yes 
  pp:dateFormat format=mm-DDD-  name=dataForm
 property=currentDate /
 /pp:text

 Which produces this HTML

  input type=text name=currentDate value=25-Oct-2001 

 How do write an ActionForm method mutator that converts the
 String form 25-Oct-2001 to a proper java.util.Date.
 Should I write a void setCurrentDate( String ) method?

 Subject:  help me with this  numberformat exception please

 hi everybody,
 i spent my whole afternoon with a stupid numberformat exception.
 at last i gave up,and decided to bring here.
  can someone help me with this please, or I will get crazy.
 i am using tomcat 4 on windows 2000.
 this jsp file takes a request parameter no, which is an integer.
 but it seems that it can't receive or read this parameter correctly.
 i call this jsp from my from browser as :
 http://localhost:8080/new/newscont.jsp?no=1
 but i always have the same exception ( numberformat exception)

 below is my code:

 %@ page language=java contentType=text/html; charset=BIG5  %
 %@ page import=java.sql.*,java.util.*,org.gjt.mm.mysql.* %
 HTMLHEADTITLENEWS/TITLE
 META content=text/html; charset=big5 http-equiv=Content-Type
 /HEAD
 BODY  bgColor=pink leftMargin=0 text=#00 topMargin=0 marginheight='0'
 marginwidth='0'BR

 %! Connection conn;
  String ndate,subject,news;
   int no;
   Statement stmt;
   ResultSet rs;
   String sql; %
  %

  Class.forName(org.gjt.mm.mysql.Driver);
  if ((request.getParameter(no)!=null)
 (request.getParameter(no)!=)){
  try {


conn = DriverManager.getConnection(jdbc:mysql:///yilmaz);
 no=Integer.parseInt(request.getParameter(no));
 sql=select ndate,subject,news from new+no;
  stmt = conn.createStatement (sql);

 rs = stmt.executeQuery ();
while (rs.next() ) {
 ndate=rs.getString(1);
 out.println(ndate);
 subject=rs.getString(2);
 out.println(subject);
 news=rs.getString(3);
 out.println(news);
 }
 }

catch (SQLException e)  {
   out.println(SQLException caught + e.getMessage());
   e.printStackTrace();
   }
   catch (NumberFormatException nfe) {
   out.println(NumberFormatException
 caught +nfe.getMessage());
}
finally {
   rs.close();
stmt.close();
conn.close();
} }
%

 
 the whole other followings are normal html code
 
 when i run my JSP it throws :
 org.apache.jasper.JasperException: Unable to compile class for JSP
 ...
 root cause :
 java.lang.NumberFormatException: mysql
 at java.lang.Integer.parseInt(Integer.java:414)
 at java.lang.Integer.parseInt(Integer.java:463)
 ...
 
 I AM LOOKING FORWARD TO YOUR HELP OR SUGGESTIONS
 THANKS A LOT IN ADVANCE
