Hey JSP gurus is this code legal
for(int j=hst;j<hsp;j++){
if (info[0].elementAt(j).equals("JackDiamonds")){
info[0].replace(%><img src=images/code.gif><%);
out.println(info[0].elementAt(j));
}I'm getting syntax error for my 3rd line
thanks
KT
yes it is a vector and I don't think "remove" is a method in vector.
but here is the code
java.util.Vector info[] = wagerhist.getGameInfo();
int rotation = ((Integer)info[0].elementAt(0)).intValue();
info[0].removeElementAt(0);
out.println(rotation);
for(int i=0;i<rotation;i++){
int h = 17;
int d = 6;
int hst=h*i;
int hsp=hst+h;
int dst=d*i;
int dsp=dst+d;
for(int j=hst;j<hsp;j++){
if (info[0].elementAt(j).equals("JackDiamonds")){
info[0].setElementAt("<img src=images/code.gif>");
out.println(info[0].elementAt(j));
//for(int j=dst;j<dsp;j++){
//out.println(info[0].elementAt(j));

I'v got a piece of code that was created to send some parameters to JSP page via POST method. But in server page I can't retrieve this parameters, please help me and try to find "main" bug in this code.
try {
URL url = new URL("http://localhost/index.jsp");
HttpURLConnection httpCon = (HttpURLConnection)url.openConnection();
httpCon.setRequestMethod( "POST" );
httpCon.setDoOutput( true );
String body = URLEncoder.encode("name=Oleg", "UTF-8");
httpCon.setRequestProperty( "Content-length", Integer.toString( outBody.length() ));
httpCon.setRequestProperty( "Content-type", "application/x-www-form-urlencoded" );
OutputStream os = httpCon.getOutputStream();
PrintWriter ow = new PrintWriter( os );
ow.print( body );
ow.flush();
ow.close();
} catch (....) {
}Hi
You must not encode all the body just the values of the parameters.
You can do as following in order to send a post request with 2 parameters
String param1 = "Co & sons";
String param2 = "ltd.";
String encParam1 = URLEncoder.encode(param1,"UTF-8");
String encParam2 = URLEncoder.encode(param2,"UTF-8");
String body = "param1="+encParam1+"¶m2="+encParam2;
OutputStream os = httpCon.getOutputStream();
PrintWriter ow = new PrintWriter( os );
ow.print( body );
ow.flush();
//read the response from the jsp
InputStream inS = httpCon.getInputStream();
byte[] buff = new byte[5000];
StringBuffer sbuff = new StringBuffer();
int nrBytes ;
while( (nrBytes = inS.read(buff, 0, 5000))!=-1) {
sbuff.append(new String(buff,0,nrBytes));
inS.close();
ow.close();
...This is the jsp page which gets the parameters
<%
String param1 = request.getParameter("param1");
param1 = new String(param1.getBytes(),"utf-8");
String param2 = request.getParameter("param2");
param2 = new String(param2.getBytes(),"utf-8");
%>I hope I helped you.

Using jsp variable in java code
Hey guys,
I need some help hope you guys can help me.
I've declared a variable "error" in a jsp. how do I access this variable in the java code whice resides in the same jsp page.
I know I can use java variable in jsp code using
<%= sVariable %>
where sVariable was declared in the java code. but how do I access a jsp variable in java code??
Thanks very much in advanceThanks for the reply.
This is what I want to do.
I've declared a variable "error" using <c:catch var="error">I want to check the value of this variable and suppose if it contains XYZ (error variable will have a long string so I just want to check if it contains a specific value) I want to do step1 and if the variable of error is not XYZ I want to do step 2
Problem is I dont know how to check if error contains the XYZ in jsp thats why I thought java code would help here.
Can you guys suggest a better way to solve my problem.
Thanks again -

"n435991ABAP provides few tools to analyse the perfomance of the objects, which was developed by us.
Run time analysis transaction SE30
This transaction gives all the analysis of an ABAP program with respect to the database and the non-database processing.
SQL Trace transaction ST05
by using this tool we can analyse the perfomance issues related to DATABASE calls.
Perfomance Techniques for improve the perfomance of the object.
1) ABAP/4 programs can take a very long time to execute, and can make other processes have to wait before executing. Here are some tips to speed up your programs and reduce the load your programs put on the system:
2) Use the GET RUN TIME command to help evaluate performance. It's hard to know whether that optimization technique REALLY helps unless you test it out.
3) Using this tool can help you know what is effective, under what kinds of conditions. The GET RUN TIME has problems under multiple CPUs, so you should use it to test small pieces of your program, rather than the whole program.
4) Generally, try to reduce I/O first, then memory, then CPU activity. I/O operations that read/write to hard disk are always the most expensive operations. Memory, if not controlled, may have to be written to swap space on the hard disk, which therefore increases your I/O read/writes to disk. CPU activity can be reduced by careful program design, and by using commands such as SUM (SQL) and COLLECT (ABAP/4).
5) Avoid 'SELECT *', especially in tables that have a lot of fields. Use SELECT A B C INTO instead, so that fields are only read if they are used. This can make a very big difference.
6) Field-groups can be useful for multi-level sorting and displaying. However, they write their data to the system's paging space, rather than to memory (internal tables use memory). For this reason, field-groups are only appropriate for processing large lists (e.g. over 50,000 records). If you have large lists, you should work with the systems administrator to decide the maximum amount of RAM your program should use, and from that, calculate how much space your lists will use. Then you can decide whether to write the data to memory or swap space.
Use as many table keys as possible in the WHERE part of your select statements.
7)Whenever possible, design the program to access a relatively constant number of records (for instance, if you only access the transactions for one month, then there probably will be a reasonable range, like 1200-1800, for the number of transactions inputted within that month). Then use a SELECT A B C INTO TABLE ITAB statement.
8) Get a good idea of how many records you will be accessing. Log into your productive system, and use SE80 -> Dictionary Objects (press Edit), enter the table name you want to see, and press Display. Go To Utilities -> Table Contents to query the table contents and see the number of records. This is extremely useful in optimizing a program's memory allocation.
9) Try to make the user interface such that the program gradually unfolds more information to the user, rather than giving a huge list of information all at once to the user.
10) Declare your internal tables using OCCURS NUM_RECS, where NUM_RECS is the number of records you expect to be accessing. If the number of records exceeds NUM_RECS, the data will be kept in swap space (not memory).
11) Use SELECT A B C INTO TABLE ITAB whenever possible. This will read all of the records into the itab in one operation, rather than repeated operations that result from a SELECT A B C INTO ITAB... ENDSELECT statement. Make sure that ITAB is declared with OCCURS NUM_RECS, where NUM_RECS is the number of records you expect to access.
12) If the number of records you are reading is constantly growing, you may be able to break it into chunks of relatively constant size. For instance, if you have to read all records from 1991 to present, you can break it into quarters, and read all records one quarter at a time. This will reduce I/O operations. Test extensively with GET RUN TIME when using this method.
13) Know how to use the 'collect' command. It can be very efficient.
14) Use the SELECT SINGLE command whenever possible.
15) Many tables contain totals fields (such as monthly expense totals). Use these avoid wasting resources by calculating a total that has already been calculated and stored.
Some tips:
1) Use joins where possible as redundant data is not fetched.
2) Use select single where ever possible.
3) Calling methods of a global class is faster than calling function modules.
4) Use constants instead of literals
5) Use WHILE instead of a DO-EXIT-ENDDO.
6) Unnecessary MOVEs should be avoided by using the explicit work area operations

Performance tuning for Data Selection Statement
http://www.sap-img.com/abap/performance-tuning-for-data-selection-statement.htm -
Can anybody tell me the problem with this code when compiled in jdk1.4
Can anybody help me find out the error in this code.
Try to drag a file from your desktop and drop it on the first textpane on my GUI. Then try to drag another file. This time the dragdrop event handler throws a null pointer exception. This happened when I compiled the code with jdk1.4. With jdk1.3 it is working fine. Actually, I need jdk1.4 to get the systemicons for the files I drop on my desktop.

BinaYou should have commons-fileupload.jar in common/lib or in ur applications lib directory( I mean WEB-INF/lib). Dont forget to set the build path to commons-fileupload.jar in Eclipse.
Go to
project > properties > Java Build Path > libraries > click on Add External Jars button > choose ur commons-fileupload.jar file > click on OK -
How to write this code ?
I need to write 3 classes that each one can get to the other with the same instance of the class , so how do i write this code ?
thanks a lottry out singleton pattern with all the three classes. following link may help...
http://www.javareference.com/jrexamples/viewexample.jsp?id=25 -
I would like your comments on this code. Doesn't it have a few oppertunities? I know it's jsp, but question is not directed toward the jsp, just the logic/syntax/etc. How about the == for starters?
<%
String z_Desc = (((String)hshipTrackSummaryDocList.get("Z_DESC")) == null) ? "" : (String)hshipTrackSummaryDocList.get("Z_DESC");
if (z_Desc == "" ) {
%>
<%
}else {
%>
<%=(((String)hshipTrackSummaryDocList.get("Z_DESC")) == null) ? "" : (String)hshipTrackSummaryDocList.get("Z_DESC")%></font>
<%
%>Hi mlovern! This code has several opportunities for "improvement". I noticed that the get("Z_DESC") method is called on hshipTrackSummaryDocList object several times. Each time, it returns the very same value. Hence, in the interests of efficiency, it's a better idea to call it once, save the return value and then use the latter.
Also, I'm not too clear about exactly what you intended to do in the else clause. As it stands, your else clause will cause the JSP to fail.
Be very careful while using the "==" operator while comparing strings. That causes object comparison, not object content comparison. The latter is the required test most of the time. Also, while comparing the contents of the strings, it's better to call the equals() method on the empty string or a constant string. So, if I needed to compare a test value against an empty string or a constant, here's how.
if ( "".equals( testString ) )
// do something
else if ( SOME_CONSTANT.equals( testString ) )
// do something
}In the above code, even if testString was null, a runtime exception will not be generated. However, if the equals() method was called on testString and it happened to be null, you'd be looking at an exception.
Here's how I would have written the code you supplied.
String zDescValue = (String) hshipTrackSummaryDocList.get( "Z_DESC" );
if ( zDescValue == null ) zDescValue = "";
if ( "".equals( zDescValue ) )
// do something useful
else
// do something else
}I've also come across similar situations. In order not to repeat the same code everywhere, I've wound up writing a couple of utility methods to assign "" to a string if it's null. Here are those methods.
public static String processStringValue( String inputString, String defaultValue )
return ( inputString == null ? defaultValue : inputString );
public static String processStringValue( String inputString )
return processStringValue( inputString, "" );
}Finally, you may want to be careful about the code fragments you post. From your post and profile, I can guess where you work. Your employer may or may not care if parts of their code start showing up on the Internet. It's better to create a general piece of code that approximates what you want to convey. However, it's better to be safe than sorry.
Hope this helps!
Cheers! -
Hi master
Sir I use orace 9i easily in java class with following code
===========
import java.sql.*;
public class ttst {
public ttst() {
public static void main (String args [])
try{
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@fahim:1521:aamir","muhammad","mfa786");
Statement stmt = conn.createStatement();
ResultSet rset = stmt.executeQuery("select accid from accbal where accid='K1101'");
System.out.println ("going for connection");
while (rset.next())
s= rset.getString("accid");
System.out.println (s);
catch(Exception e){
e.printStackTrace();
system give me right result
and when I use jsp with this code
<HTML>
<%@ page import="java.sql.*,java.util.*" %>
<% String url="jdbc:oracle:thin:@fahim:1521:aamir";
Connection con;
Statement stmt;
ResultSet rs;
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
con = DriverManager.getConnection(url,"muhammad","mfa786");
stmt=con.createStatement();
%>
<%
%>
<select name="ltpid">
<%
try{
rs= stmt.executeQuery("select accid,title from chartofacc");
while (rs.next()){
%>
<option Value=<%=rs.getString(1)%>> <%=rs.getString(2) %> </option>
<%

but jsp page not run
please give me idea how I how my oracle data in jsp page
thank
aamirsir i post my problem but they reply me it java problem not oracle problem
*** oracle reply**********
You metioned that you use
jdbc:oracle:thin:@<ip or hostname of machine where your db is installed>: 1521:aamir , description to connect the remote database. So, I think it's not related to your tnsname.ora problem. It's only java oracle thin connection string. Please check this string, make sure the ip and database service name is right.
one more thing, use sqlplus check your tnsname.ora, if ok, then try to check jdbc and make sure the jdbc driver match to oracle server.
sir please give me idea how i show my oracle data in clinet browser
thank's

Hello, i made this code to explore the machine and copy the file from one place to another! Ok.. it works.. but whem i compile the code.. 3 FileCopy.classes are generated... in fact, are four.. one named FileCopy.class, other named FileCopy$1.class, other FileCopy$2.class, other FileCopy$3.class..
i�m not sure but, if i compile this code,, only one FileCopy.class could be generated.. i�m right? if i�m not, i will be happy if somebody tells me what is happen with my code! if it�s wrong or something like that...!

There is no problem with your code.
The three files are created by the compiler because you have 3 anonymous classes within in your code.
E.g.
new ActionListener () { .....}
So when using anonymous classes these additional files are required for your app.
Hope thats ok!! -
I bought a movie with the digital copy and it gives me option to redeem it with iTunes, but when I type in the redeem code it shows a message saying: " you must insert your digital copy dvd in this computer in order to redeem this code" . The dvd is in. WTH? This is especially with FOX movies, I never have trouble with Universal Picture movies.
Thanks for your reply, but you might have misunderstood it a bit. I'm NOT trying to buy a movie. ****, I'm not even in the actual Apple Store, when this happens I'm in the library not the Store part of iTunes.
To clarify - I have purchased a physical copy of a movie which came with another physical copy which contains the digital copy. The digital copy is on the DVD, all I need is just to transfer this file to my iPod Touch, for example, I'm not trying to download it from the store or repurchase it and it's not any gift code that I've received, the digital copy is on the disc. This is the first time ever that I've purchased something on a disc and I'm not allowed to access it because the disc hasn't been purchased within my country.
So again - I'm not attempting any purchase or download any purchased digital copy - it's on a DVD I own physically so... why is even the region of my Store relevant, the code I enter is (as I assume) just supposed to check if it's a legal genuine copy (which it is, as I've said - there are 6 discs in the pack: 3 movies on 3 Blu-rays and 3 DVD containing these digital copies of them). If I own it, I think that's proof enough that I have the right to use it. I just don't get it. I fully agree with you and understand your point if there was any purchase going on here, but it's not, it's just - I put a disc into my computer and I can't access it -
i recently bought a $20 gift card to redeemed in my new ipad.. i redeem my code in my ipad account . I lost my internet connection just before i could see a confirmation. i reconect and check my account no money credited..i tried to redeeem again but a message sent saying this code had been redeem.. where is my credits? How I can i retrive the $20 gift card.
Hey tiger.jor,
I would first check and see if the gift card's balance has been applied to your account:
Tap the iTunes Store, App Store, or iBooks.
Scroll to the bottom of the Featured tab.
Sign in with your Apple ID.
If you have a credit balance, you'll see it below your Apple ID.
from: iTunes Store: iTunes Gift balances

Is it true that JSP creates Servlet java code?
I am working with JSP.
My web server is tomcat.
Is it true that JSP creates Servlet java code of JSP files when it executes? If so how can I view them?Yes..it is true..
to find out..do this..
on purpose leave a bug in ur jsp that will generate a compilation error. So in ur browser some exception will be shown.That exception message will have the clue to the java file (e.g
error in compiling _XYZ.java).You can manually search for this file..
(If the copilation is successful, then this java file is deleted by the server.)
