Code to connect java to LDAP

Hi,
I am in urgency to get code to connect LDAP server on Domino server,just tell me where i can find a simple code to connect LDAP server using java.

You can use the JNDI API for this
The tutorial contains the basic code examples for connecting to LDAP using this API:
http://java.sun.com/products/jndi/1.2/javadoc/
You'll also need to download the JNDI API from:

You can set ldap_auth=none for anonymous user.
User/password is mandatory otherwise. Please refer to http://docs.oracle.com/cd/E21764_01/integrate.1111/e12644/appendix_ldap_driver.htm#CHDHCABH

NullPointerException at com.sun.jndi.ldap.Connection.run(Connection.java:52

We are using the Sun jndi 1.2.1 files from a Java client to
access the IBM SecureWay Directory 3.2 server. Our test case is
retrieving entries using the ctx.getAttributes (String, String[])
method. Occasionally we are receiving the following error.
java.lang.NullPointerException
at com.sun.jndi.ldap.Connection.run(Connection.java:525)
at java.lang.Thread.run(Thread.java:481)
The java.lang.NullPointerException is coming from the Sun JNDI file.
Our program is not catching this exception.
Has anyone seen this problem before and have any ideas on how this can be resolved?

Download and use LDAP 1.2.3 or JDK 1.3.1.
The problem should go away.

Hi baftos,
I tried to telnet remote windows machine from my local machine on port 23, its not connected and given error message like "Connect failed".
As your response, if we can telnet to remote windows machine from local machine then we can connect from Java. Is it correct ?.
Can you please help me to resolve this issue. And also please confirm the port (23) is correct, which I was used to connect remote machine from telnet.

Praveen

Urget Help --- Please give me the core java code that connects to UNIX ser

Can anyone provide the core java code that connects UNIX server after verifying credentials and allow to implements UNIX commands through java program?

no, you don't want to do that.
You want to connect yourself, which Java is quite capable of doing, rather than go through some 3rd party client program that's not only specific to a particular operating system but not guaranteed to be installed at any particular machine or if it is to be installed in such a way that you can start it from your Java program.
And then there's the little matter of figuring out the external API to use that program in the way you intent to (if it has one).

Connection pool for ldap

Hi
My application is an interface to ldap directory. I have not used any ldap open source api to retrieve data from ldap. I have written connection pool that will help the application to connect to the ldap. It's working fine, but it's creating threads which are not invited.
ConnectionPool class takes care of the connection storage and creation, while Housekeeping thread relases these connection when idle after a given time.
Can someone please help in finding the problem in the code that creates additional threads.

Hi,
As the connection pool implmentation has the bug of not extending more than the min size, workaround I use is MIN_CONN=100 and MAX_CONN=101,and just waiting for the bug to get fixed. (using Netscape SDK for java4.0)

Unable to connect to LDAP server
I have imported atr certificate also by using command:
"keytool -import -alias jag -file c:\x225.cer -keystore c:\j
2sdk1.4.2_15\jre\lib\security\cacerts"
I am running my java code from eclipse. And do i have to set any thing in eclipse for certificate. I Have imported certificate from command prompt.
Can any one please help me.It is very important for me.
Please its very urgent.
THanks,
Ankush Patni

As previously said network is a possible cause.Other things could be time on filer is too far off time on DC.AD object for filer has been deleted or change by a Windows admin.If all users are experiencing a problem, you may need to rebind it to AD - run CIFS setup at command prompt

Hi,
Here are the two ways of connecting to a database through coding:
////1////
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
java.sql.Connection conn= java.sql.DriverManager.getConnection("jdbc:microsoft:sqlserver://<IP>:<port>;user=<abc>;password=<xyz>;database=<DB name>");
////2////
InitialContext initialContext = new InitialContext();
DataSource dataSource = (DataSource)initialContext.lookup("jdbc/SRI");

I do not how to use JPoller, put it looks very advanced.
Or you can use a simple code in (java/perl/c/what so every u know)
void main(){
while (true) {
checkDirectoryAndReadNewCommandsAndWriteNewOutputs();
Thread.sleep(waitTime);
}and put your program on your windows/linux startUp
Or you can learn using sockets in java and write your own html service with port 80 (I did some experiments)
Or you can try to use WebService example from Netbeans program (I tried it worked for me)
Or you can learn J2EE (I have never find the time to look at)
Or ... many ideas, to time :)

Client Code not connecting to WebLogic 8.1 with Mutual Authentication

I am trying to connect to a WebLogic 8.1 web services application. The weblogic instance has mutual authentication enabled, so the client needs to send a certificate when it does an SSL handshake with the server. I am trying to connect with standalone Java JUnit tests. Both the web services and the JUnit tests are using Apache Axis 1.4.0. I've obtained what I believe to be the appropriate certificates from the weblogic administrator that configured the mutual authentication. There is a certificate for the machine I'm trying to connect to, and two other certificates in the chain (three certificates all together, including the root). I've tried several different methods of putting those three certificates in keystores and trust keystores, reading in those keystores in my java code, and connecting to the web services, and I always end up with the same error in the WebLogic server logs. "Certificate chain receved from <ip address> was incomplete."
Here is an example of my code:
I initialize like so:
     Properties tempProperties = // (here is where I obtain my properties from a properties file... code removed for security reasons)
     System.setProperty("javax.net.ssl.trustStore", tempProperties.getProperty("trust.keystore.file"));
     System.setProperty("javax.net.ssl.trustStorePassword", tempProperties.getProperty("trust.keystore.password"));
     System.setProperty("javax.net.ssl.trustStoreType", "jks");
     System.setProperty("javax.net.ssl.keyStore", tempProperties.getProperty("keystore.file"));
     System.setProperty("javax.net.ssl.keyStorePassword", tempProperties.getProperty("keystore.password"));                         System.setProperty("javax.net.ssl.keyStoreType", "jks");
     System.setProperty ( "java.protocol.handler.pkgs", "com.sun.net.ssl.internal.www.protocol" );
     Security.addProvider ( new com.sun.net.ssl.internal.ssl.Provider ( ) );
I bind to the appropriate port and locate the service, etc. using auto-generated methods descendant from Apache Axis. No matter what I try, I get the same results. The client says: main, handling exception: javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure
The server log says: Certificate chain received from <ip address> was incomplete.
I've even tried implementing a custom SSL handler as described here http://alweb.homeip.net/dw0rm/dblog/?p=38, and I can verify by stepping into my code that everything gets initialized and set up correctly, and that all three certificates in the chain that I need are obtained from my keystore, but I still get the same error on the client and the server. I've enabled ssl handshake debugging on my client and I can see the whole certificate chain being output to the debug console.
Any idea what I might be doing wrong?

My guess would be that the server is not able to validate your certificate. Make sure that the CA for your certificate is trusted by WLS.
I always like to debug something like this by add -Djavax.net.debug=ssl to both the client and server. It should give you a complete picture of what is going on.

Basically it takes the content from a BLOB column of the wpg_document table, unzip it using java.util.zip package, look for the file content.xml and parse it using Oracle XML toolkit.
Using an open source utility which replace java.util.package (http://jazzlib.sourceforge.net/) it works perfect because is a pure java application.
Best regards, Marcelo.
PD: I am using Oracle 9.2.0.2 on Linux.

The cause of errors was a dying Westen Digital drive, specially the 48G partition reserved only for $ORACLE_BASE (/dev/sdb3 mounted on /opt/oracle).
A simple quick scan of unmounted partition (badblocks -v /dev/sdb3) reported more than thousand new bad blocks (compared to the last scan six months ago). Although I strongly believe, specially in the case of WDC drives, that the best utility to "repair" bad blocks is the one that opens a window and prints the message: "Go to the nearest shop and buy a new drive", I was very curious to prove my suspicion just on this drive. After zero-filling the partition with dd, then formatting it (mke2fs -cc) and mounting again, the 11g installation and database creation (on the same partition) successfully completed, performing fast and smoothly. To make sure it was not a casual event, I repeated the installation once again with full success. The database itself is working fine (by now). Well, the whole procedure took me more than four hours, but I'm pretty satisfied. I learned once again - stay away from Western Digital. As Oracle cannot rely on dying drive, my friend is going tomorrow to spend a 150+ euro on two 250G Seagate Barracudas and replace both WDC drives, even though the first drive seems to be healthy.
In general there is no difference between loading correct data from good disk into bad memory and loading the incorrect data from dying disk into good memory. In both cases the pattern is damaged. For everyone who runs into the problem similar to this, and the cause cannot be easily determined, the rule of thumb must be:
1. test memory and, if it shows any error, check sockets and test memory modules individually
2. check disks for bad blocks regardless of the result of memory testing
Therefore I consider your answer being generally correct.

Can' t connect Java with MySQL

My goal is to connect Java with MySQL. I found many solutions on Internet, but I always get the same mistake:
SQLException: No suitable driver
SQLState: 08001
VendorError: 0MySQL works fine alone or with php.Only thing left me to think is that the installed versions are not compatible for this mysql-connector-java-5.0.4
I don't believe that could be a reason.
Installed versions are:
Apache Tomcat 5.5.20 Server
Apache HTTP Server 2.2.4
PHP 5.2.0
MySQL 5.2
jre 1.5.0_11
jdk1.5.0_11
Apache Tomacat JK2 connector Version: 1.2.20 File Name: mod_jk-apache-2.2.3.so
mysql-connector-java-5.0.4
I also set connector in class path: C:\mysql-connector-java-5.0.4;C:\mysql-connector-java-5.0.4\mysql-connector-java-5.0.4-bin.jar;C:\mysql-connector-java-5.0.4\src\com\mysql\jdbc
For installation I used manulas from:
http://apacheguide.org/jsp.php
http://doc.51windows.net/mysql/?url=/MySQL/ch23s03.html
Here is also a test code in java:
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
   public class Connect
       public static void main (String[] args)
           Connection conn = null;
           try {
    conn =
       DriverManager.getConnection("jdbc:mysql://localhost/first_test" +
                                   "user=monty&password=greatsqldb");
    // Do something with the Connection
} catch (SQLException ex) {
    // handle any errors
    System.out.println("SQLException: " + ex.getMessage());
    System.out.println("SQLState: " + ex.getSQLState());
    System.out.println("VendorError: " + ex.getErrorCode());
   }i'm desperate, please help or tell me someone who'll know the answer.
Thank You in advance

hey buddy .. it seems yr code is wrong .. in getconnection () method u should also specify the port ,which u r not doing ...
the default port for MySQL is 3306 ... see below i am giving you a sample code ... its working fine .. and dont forget to put the MySQL driver jar path in to classpath and also copy the jar into common/lib folder of your tomcat ....
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class MySQLConnectionTest {
     public static void main(String[] args) {
new MySQLConnectionTest().connTest();
public void connTest() {
          String tableName = "portfolio"; //change as per setting
          String hostName = "10.81.9.39"; // please change for the target database ip or hostname
          String dbPort = "3306"; //change if not using the default
          String dbName = "tradingsystem"; //change as per the given DB name
          String username = "root"; //change as per setting
          String password = "password"; //change as per setting
          System.out.println("before try");
          Double data=0.0;
     Double data1=0.0;
          try {
Class.forName("org.gjt.mm.mysql.Driver");
               System.out.println("before driver manager");
Connection conn = DriverManager.getConnection("jdbc:mysql://"+hostName+":"+dbPort+"/"+dbName, username, password);
String query1 = "select * from "+tableName+" where User_id='trader1' and Stock_Type='Equity'";
System.out.println("quesry1="+query1);
Statement stmt = conn.createStatement();
ResultSet rs1 = stmt.executeQuery(query1);
while(rs1.next())
     System.out.println("hiiiiii for rs1");
     System.out.println(rs1);
     Quantity=(Integer)rs1.getObject(5);
     MarketPrice=(Double) rs1.getObject(8);
     data=Quantity*MarketPrice;
     data1+=data;
     System.out.println("data1="+data1);
     i=0;
rs1.close();
stmt.close();
conn.close();
} catch (ClassNotFoundException e) {
e.printStackTrace(System.err);
} catch (SQLException e) {
e.printStackTrace(System.err);
i hope it will work for u...

Ghost connections "Java(TM) 2 Platform Standard Edition"

We have a server application with multiple threads each using JDBC connections. On the Database server (MS SQL Server 7) we notice more and more connections with the SQLQueryAnalyzer-ProgramName "Java(TM) 2 Platform Standard Edition". But all our (known) connections have custom names or the default name of the JDBC driver (jTDS). The developer of jTDS answered that the driver only have connections that are requested by the application. But we don't have connections named dbc connections "Java(TM) 2 Platform Standard Edition" ... ?

We don't use an application server, it's just a plain Java application. No frameworks and only 3rd party libs that don't handle any database connection - and the JDBC driver jTDS. As one of the developers got very angry about my bug report, because he insists that it's not the fault of jTDS, I have to rule out jTDS. That would mean that it's somewhere in my application. But I just have 1 single class that actually creates a JDBC connection, so it's not hard to debug this. And I can't see any additional connections as all of my connections get specific names and not "Java(TM) 2 Platform Standard Edition".
I searched all source code of the Java SDK, jTDS and my source code for occurences of "Java(TM) 2 Platform Standard Edition" and can't find any. I hoped that somebody knows who is using this string (and when). It sounds like general Java (SDK/JRE) is setting this name, but I haven't found it.

Hoe to connect java with mysql 5.0

I have installed the new Os. in that RHE-5 Os is there, now I want that java can connect ot mysql but , its not able connect with mysql so please guide me.

1) download mysql connector/J JDBC driver from mysql.com
2) put the driver jar somewhere where you can put it in the classpath of your application
3) use proper setup code to connect to the database (search google, tons of examples)
If at any step you have no clue what I am talking about, you need a good book to help you further.
