Fustrating equality problem, pls help

Hello ppl. Im here with a rather silly but fustrating problem...
I have a conditional like this:
String host = request.getRemoteHost();
if(host != "localhost"){
// code...
Im the localhost and the value of host is localhost but java thinks otherwise, so therefore the conditional returns false and the code is executed! WHY?? I've even tried this...
if(String.valueOf(host) != "localhost"){
// code...
That still didnt work! I dont want that piece of code executing if the host value is localhost. Help appreciated. Thanks.

Thanks jesperdj that worked a treat. I was aware of the equals() method but i wasnt quite sure how to test for unequality using the equals() method. Thanks.

Urgent: Sessions problem pls help me

Hi all,
Its already late to post this problem.pls help me urgently.
I have a servlet & two jsp's. first i request servlet, it processes something and forwards request to my first jsp. In that jsp on a button click, i'm displaying a new popup by calling showModalDialog. this dialog gets data from the same servlet but it forwards to my second jsp.(second jsp can be seen in dialog)
Now if i submit form from my second(dialog) jsp, the servlet reports that session has expired. I tried a lot but invain. any one who helps me is appreciated well by all of our forum.
waiting 4 u r reply,

It could be that you have cookies turned off and you're not using URL Rewriting.
In J2EE, the first time your browser makes a request to the server, the server responds and appends a SESSION_ID parameter to the request as well as storing a cookie with the SESSION_ID.
The second time your browser makes a request, the server checks for the cookie. If it doesn't exist it checks for the parameter. If neither exist the server assumes its the first time your browser has made a request and behaves as describe in the previous paragraph.
In your case when you submit the form if you have disabled cookies and the action attribute doesn't have the SESSION_ID paramter appended to the url, the browser will assume it's a first request. The user will not be logged in, hence your session has expired error.
To fix this you need to encode the URL in your JSP. You can use the struts html:rewrite tag or the HttpServletReponse.encodeURL method, or if you're using JSP 2.0 the JSTL c:url tag.

How to solve this problem, pls help when, I try to see remote camera system(spec dvr) from home. The Error I get is "Dual streaming is required for HTML viewing"

I had the same probelm and found that the problem lies with 64bit programs such as safari and microsoft internet explorer. I have resolved the issue on my PC based server by using a 32 bit ie and same on my mac by using the same running windows under parallels.
So far the problem with the 64 bit side of it is still to be resolved.
Hope this helps and gets you guys up and running until suchtime a 64 bit solution is found.

Hi Experts ,
I have the requirement in which if the apinumber is greater than or equal to 10 then only the rows should get inserted into the well_header_table from products_mv table.I need to use only merge concept and nothing else.
I am making use of the merge concept here .I am checking for the 10 digit condition during the updation part but same will be inserted into the well header table.This shouldnt happen .Can any one suggest me how can i filter out the insertion part so that it only inserts the rows which has api_number greater than 10 digits.I have marked my 10 digit condition that checks for the update part in bold form.
Pls help me out in resolving this issue .

Import problem,pls help!

Hi,there,
I'm new guy here,I'v got a problem about Import in table mode,I found I can import back all records successfully, but it just appends all records into the orignal table,not overwrite
it,for example, I made a export for a table with 2 records, after then I added some records into that table,
finally I made an import for that table, I found the
total of records is not recovered to 2,but just append
the records from export file,why can't I recover it to 2
record? pls help me,thanks!

All that import does is to run a bunch of SQL statements based on the content of the export file. If you look at the export file in an editor (if its small), or through type (on Windoze) or more on *NIX you will see stuff like:
CREATE TABLE x STORAGE ( ...)
INSERT INTO x col12,col2, ...
VALUES (:b1,:b2, ...
If you give imp the paramter ignore=Y, then the error generated by the CREATE TABLE (table already exists) will be suppressed, but the ata will be inserted. Note that there are no DROP TABLE or TRUNCATE TABLE commands in the export file.
If you want to restore your database to a particular point in time using import, then you will need to manually drop or truncate the tables first. You can generate the required sql from the data dictionary. something like
SET lines 1000 pages 0 feedback off trimspool on;
SPOOL drop.sql;
SELECT 'DROP TABLE '||table_name||';'
FROM user_tables;
SPOOL OFF;
@drop.sqlHTH

Weird Problem pls help.

Hi guys I have a big problem that I can't figure out. See I have a PT880 Neo and on the mobo box it says it's VIA. But when I go to install the Hyperion 4 in 1 mobo drivers my system crashes. When I boot up I get a Bsod stating my graphics card is in an infinite loop and says the video driver for my card is the problem. Also when I go to install new hardware it doesn't detect it. I checked the bios and pnp is enabled. So I put a new network card in and it will only detect it in the top pci slot so is this some kind of glitch am I downloaded the right drivers? The hyperion 4 in 1's version 455vp1 pls help

Hi
Sorry khar khar ???? Mainly any sounds from under the keyboard would be Fan or HDD either way could mean either the Fan ( if fan ) is struggling to move due to dust build up OR the hard drive is failing ,,, It's difficult to give you a firm answer without more information . Can you tell the difference between the fan noise and a hard drive noise ?? When you start up from cold does the noise start immedietly or is it only heard after say 5-10 minutes ?????? Checkurtech

Installation problem, pls help

I am trying to install Oracle 10g on SUSE 10.0.0 but when i run the ./runInstaller command, I receive an[b] error of writting to directory /tmp/OraInstall2006-03........, Please ensure this directory is writable and at least 60MB of disk space, i have checked for space using df -h /tmp, there is enough space, i think the problem has got to do with permission because @ the moment it belongs to root user, i don't know what to do, i am a novice to unix and need to install oracle today. Pls help
Usually the standard install of SuSE Linux should set the ownership and access rights to /tmp, if you want to give access to everyone on the system, just use this command (if owner/root access is available):
I have used chmod o+rwx /tmp command and still having the same error. Pls somebody help
chmod o+rwx /tmp

Of course I assume you did correctly follow installation and configuration instructions. Did you read Oracle10g/Linux Errors and Problems from Werner Puschitz ?

Audio+Video Chat works but one small problem.Pls help.

HI..
as i had posted once before in a different query's thread, i have implemented audio and video chat using AVTRansmit2 and avreceive2.
audio and video chat work well.By video chat i mean not only video but VIDEO+AUDIO as well.. just like usual yahoo video chat.
But the problem is like this:-=
I have given an option for user to switch from audio chat to video chat.
now if a user first goes to audio chat and then switched to video chat,
then the problem comes. When he's shifted to video chat i close down previous Audio chat by RTPManager.dispose() , i close the player and everything..
and then i start Video transmit/receive "ALONG WITH" audio transmit/receive..
No this time video starts but audio doesnt work ..
it says"waiting for rtp data to arrive.... "
The problem is that when this new stream of audio data comes, the receiver somehow thinks that its the same old stream since its from same transmitter IP.. and so it tries to UPDATE the previous stream.
It means there is some problem with the close method or RTPManager.dispose() which should have disposed off all the stuff much before the new connection was made.
PLS HELP ASAP>
this is crunch time for my project.

Hi anandreyvk . .
well, i had tried doing removetargets and also, i had disposed RTPManager well. As it turns out the problem was not with any of it but it was the problem of me incorrectly passing RTPManager from AVReceive2 to AVTransmit2.
Actually i am using just one RTPManager.. since i am receiving and transmitting on the same port.
i've solved the problem but i am not sure if this is the right way .. what do you think ??
is creating just one RTPManager {by that,i mean initializing it only once} a good idea ?? Since we are supposed to call both AVTransmit2 and AVReceive2 with the "LOCAL PORT" .. {which in itself is a matter of discussion though! } i and my project mate thought initializing RTPManager only once is a better option .
Whats your take on all of this ?

SQL server weird connection problem-Pls help

I m using SQL server 2005 express. My default logon mode setting is set to-SQL server authentication and I can logon to using SQL server management studio express always. I enabled TCP/IP from SQL server configuration manager. The sqljdbc.jar (JDBC driver) is set correctly in classpath and 1433 port is allowed in windows firewall. YET, I can�t connect to sql server using the following code-
import java.sql.*; public class testconn { Statement stmt; Connection con = null; String driver = "jdbc:sqlserver://"; String server = "localhost:1433;"; String db = "database=IDLC-Customer;"; String user = "userName=Tanvir;"; String pwd = "password=abcd;"; String connectName = driver + server + db + user + pwd; testconn() { try { Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); con= DriverManager.getConnection(connectName); stmt=con.createStatement(); if(!con.isClosed()) System.out.println("Successfully connected to " + "SQL server using TCP/IP..."); } catch(Exception e) { System.err.println("Exception: " + e); } finally { try { if(con != null) con.close(); } catch(SQLException e) {} } } public static void main(String args[]) { testconn tc=new testconn(); } }
My host name is- Tanvir. So, in management studio express the server name is shown- TANVIR\SQLEXPRESS
When I run the code it says-The TCP/IP connection to the host has failed.
Java.net.connectException:Connection Refused: Connect
One more thing, though 1433 port is allowed in windows firewall, I can�t connect to that port using telnet (e.g. telnet <server_host> 1433).I even disabled firewall and tried but in vain. PLEASE help me brother.

Then you, seemingly, have not configured your SQL server properly, or you have not "activated" that configuration.
(don't ask because I don't know how, or even if, you do it that way with SQL Server).
But, not being able to connect with telnet, means that nothing is listening on that port. What does the netstat command tell you?Brother,as u know that sql server use the default port 1433 even if i don't mention it.And I tried disabling my firewall and antivirus but yet I cant connect.I searched the ports using "Advanced port scanner" but the port 1433 is neither in its open ports list nor in closed port list. WHat can I do now.The port 1433 is by default used by sql server.So even if I dont mention it or set it, it should work.Isn't it? I m getting out of my mind, pls help .

FindClass() Problem Pls Help.. (URGENT!!)

Hi,
I trying to use the files from the book "JNI Programmer's Guide & Specifications" - Ch. 7., to create JVM & call a java method from c routine.
I m working on Solaris machine. JVM is 1.1, so the correct part of the version independent code runs (refer to invoke.c below)
LD_LIBRARY_PATH is set correctly. invoke.c is complied correctly with no errors. All the files namely Prog.java, Prog.class, invoke.c, a.out are in the same directoy "/home/top/atm".
When executable file is run. JVM is created. But FindClass() returns with NULL value. !!!
When I try to run Prog.java from the commandline using "java Prog Hello" it runs good.
It just simply won't find the Prog.class in it's current directory. ???
If instead, "java/util/Date" is passed to FindClass(), it finds it.
The classpath in the program is also modified & there is no typo error or case-sensitivity related errors.
I m also printing classpath passed to JVM in the program. It has my included path "/home/top/atm", along with other system classpath(s).
I m banging my head over this problem, since 2 days. Hence I tried to use reference implementation files. It still will not work..
Can anyone pls be patient & help me. I'll really appreciate this.
Thanks a lot,
Following is the code of 2 files..
Prog.java

----------------------------------------

Hi , I got the exact same problem as you did. Can you
please let me know if you solve this issue already ?When FindClass returns null it means it threw an exception. The first step is to get that exception and print it out.
The error is probably class not found. And just as with java only that means your class path is not correct.
