ClassNotFoundException while establish connection with mysql

Hi friends,
While registering the JDBC driver for MySQL by following statement,
Class.forName("com.mysql.jdbc.Driver").newInstance();
It throws Runtime error as ClassNotFoundException for "com.mysql.jdbc.Driver" class.
I've set the following environment variables in Windows to use MySQL Connector/J,
C:\j2sdk1.4.2_04\jre\lib\ext\mysql-connector-java-3.0.17-ga-bin.jar\.
Can anyone tell me whats the coz for this problem?And how i resolved this?
Regards,
Sachin Warang.

it should be:
Class.forName("org.gjt.mm.mysql.Driver");

Hi,
I am using JCAPS 5.1. I tried to insert data to mysql database table.
But i got following error
java.sql.SQLException: Error in allocating a connection. Cause:
Physical Connection doesn't exist.
My intention is to read file in which data are comma seperated and to
populate those values to a mysql 5.0 database table.
Sample DATA in file [test.txt]
111,gg,23,MFG
112,hh,24,MFG

While creating JDBC OTD there is no problem in establishing connection with database. But after deploying i got above error.
I have used Mysql 5.0 Connector/J JDBC driver. Added JDBC driver jar files to following directories as required.
1) C:\JavaCAPS51\logicalhost\is\lib
2)C:\JavaCAPS51\logicalhost\is\domains\test\lib
Steps i have followed as per JDBC-ODBC -eway user guide doc.
1) Created USerDefined OTD and added necessary fields
2) Created JDBC OTD.
3) Created JAVA collaboration and do business process for inserting
4) Mapped all components by creating in Connectivity MAp
5) created necessary external systems in envrionment explorer.[JDBC External System and File External System]
6)Created Deployment profile
5) Deployed it.
After deploying it gives error as
java.sql.SQLException: Error in allocating a connection. Cause: Physical Connection doesn't exist
Please let me know the solution for problem.

In the environment definition,
-> External Application JDBC
-> Properties
-> Outbound JDBC Connection
You have the database URL in the "DriverProperties" field
Valid URL would be : jdbc:mysql://localhost:3306/caps
!! The doc says that this field is optional !! Seems to be an error in the doc:
Hope this helps

Problem is establishing connection with MYSQL with JAVA on windows

i have installed MYSQL 3.23.54 for window XP and a JDBC connector mysql-connector-java-2.0.14.
i have set the classpath for JDBC driver as
C:\> set CLASSPATH=\path\to\mm.mysql.jdbc-[version];%CLASSPATH%
and my code for testing the connection is
import java.sql.*;
public class Connect
     public static void main (String[] args)
          Connection conn = null;
          try
               String userName = "saqib";
               String password = "123";
               String url = "jdbc:mysql://localhost/test";
               Class.forName ("org.gjt.mm.mysql.Driver").newInstance ();
               conn = DriverManager.getConnection (url, userName, password);
               System.out.println ("Database connection established");
          catch (Exception e)
               System.err.println ("Cannot connect to database server");
          finally
               try
                    if (conn != null)
                         conn.close ();
                         System.out.println ("Database connection terminated");
               catch (Exception e) { /* ignore close errors */ }
. the problem i'm facing is that when i compile and run the program the following message is generated.
Exceprion in thread "main" java.lang.NoClassDefFoundError: Coonect
please help me out to establist the connection. is the classpath which i have set is correct. i have placed the unziped driever in the folder c.
thanks
Saqib

Maybe you should have typed "Connect" instead of "Coonect" at the command line?

Database connection with mysql

i have my server as follows:

JobImpl j = new JobImpl();
Naming.rebind("//"+"localhost"+"/JobImpl",j);
System.out.println("Registered");

and my interface implementation:

import java.sql.*;
public class JobImpl extends UnicastRemoteObject implements JobInt
String host="localhost";
String user="root";
String pass="admin";
String db="db";

Statement st;
public JobImpl() throws RemoteException
super();
try
Class.forName("com.mysql.jdbc.Driver");
conn = "jdbc:mysql://" + host + "/" + db + "?user=" + user + "&password=" + pass;
Connection Conn = DriverManager.getConnection(conn);
st = Conn.createStatement();
catch (Exception e)

try
rs = st.executeQuery("Select name from job whwre jobno="+jobno);
rs.next();
return(rs.getString("name"));
catch (Exception e)
e.printStackTrace();
return null;
when i 'javac JobServer' on the command prompt, i have the following error:
problem while establishing connection java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
Exception occured in JobServer ... java.rmi.ConnectionException: Connection refused to host: localhost; nested exception is :
java.net.ConnectionException: Connection refused: connect
apparently theres a problem with my database connection... the connection isnt right? plz help

problem while establishing connection
java.lang.ClassNotFoundException:
com.mysql.jdbc.DriverSo fix that first. It's just a matter of installing the MySQL JAR file(s) in the appropriate place, i.e. somewhere on your CLASSPATH. Read their documentation.

SQL Server Reporting services. failed to establish connection with project server. verify the url is correct.

Dear All,
I'm working on reporting of Project Server 2010, while configuring SQL SERVER REPORTING SERVICES faced issue after two complete days of troubleshooting along with this gone through plenty of forums, unable to figure out any solution. So finally posting on
technet in order to find solution.
ISSUE/PROBLEM:
At initial configured the SQL REPORTING CONFIGURATION to sharepoint integrated database (SQL SERVER is installed on seperate machine), change the service to Domain Account and also installed sharepoint add in on server story was fine at this point. Furthur
moving to SHAREPOINT ADMIN console and while configuring the Sharepoint Integrated Reporting continuously facing this error:
Failed to establish connection with report server. . . . (Snapshot is attached for your further reference).
My point of concern is that whenerver i try to open the REPORT SERVER URL on project server machine it prompts me to enter username and password but whenever i insert the domain credentails it didnt accept though it can be accesible by using the credentials
of Local Admin of sql server machine. So i wana come to know whether its permission issue if yes then where i should mention the domain credentials.?
REGARDS DANISH DANIE

Dear Paul,
I am able to open the URL (http://psdb/ReportServer )using
domian credential and page open with these contents
Reporting Services Error
The configuration parameter SharePointIntegrated is set to True but Share Point Object Model cannot be loaded
Second,
Configured the SPN on domain controller , performed the steps required to change the AUTHENTICATION in rsreportserver.config
file also done the registry settings to disable the loop back settings.
Same error still ! .... what should i do now ???

Essbase Error(1021001) Failed to Establish Connection With SQL Database...?

Hi there!
I am very new in Essbase and I am receiving the error message quoted below while trying to load data in a Cube. Weird thing is that we have checked all connections already and they are working correctly, however this process is still failing.
If someone can give us an idea to troubleshoot it, that would be really appreciated.
Thanks very much in advance for any help and regards!

So, we checked the database and noticed the schema and their views were damaged and -due to this- they lost all their properties (like data types, for example). So, we had to recompile all of them in order to avoid any loss of data. This was done in TOAD, as per the following info: https://support.quest.com/SolutionDetail.aspx?id=SOL66821
Finally, once all the views on this schema were rebuilt and fixed, we were able to deploy the Cube again.
Hope this help in the future. Cheers!!

I used to be able to email photos from my Lightroom software 5.7 for MAC quite successfully. I needed to change my password several days ago in my gmail account. Now when I try to email photos I receive a message saying "Failed to establish connection with the outgoing email server. Please make sure you have entered the email account and password correctly."
I have been trying to get help from Adobe for 3 days. I have sent a message through "Get Support", 2 days ago, but no one has contacted me. I have tried by phone, but no one will help me. When I purchased Lightroom in May, 2014, I was able to receive phone help. I am now told that I don't qualify because I am not a Creative Cloud customer. I have been assigned a case number 186291729.
PLEASE HELP ME FIX THIS PROBLEM

I, too, have this problem. I see no one is responding with a solution? Hello? Can someone please advise?
Oh, and, yes, I have manually verified repeatedly that the information I gave to Lightroom is correct, and I still get the same error message when I try to validate.

Unable to establish connection with SQLServer from Java Application

Dear All,
I am facing the issue of establishing connection with SQL Server from Java project developed in NWDS. I am writing a jaas plug-in, as a part of that I am writing a login module to authenticate a web application through jaas, and I got need of fetching some data from SQL Server which is located in remote host. I am getting error in the line of code
<b>Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver")</b>
I also added the 3 jar files (msbase.jar,mssqlserver.jar,and msutil.jar) to my login module project and copied the same files at C:\usr\sap\J2E\JC01\j2ee\cluster\server0\bin\ext\MSSQL.
My MI Landscape is j2ee stack + abap stack +WAS 6.40 with MAXDb as a database.
Could anyone please let me know the solution if you are aware of it.
Thanks and Regards,
Kishore

I solved it by writing the following code
Connection con;
Statement stmt;
DataSource ds;
Context ctx;
ctx = new InitialContext();
if(ctx == null) throw new Exception("Boom - No Context");
ds=(DataSource)ctx.lookup("jdbc/SQLDB");
con = ds.getConnection();
stmt = con.createStatement();
String query = "SELECT * FROM SubjectBIR where Subject_ID='" + user + "'";
ResultSet result = stmt.executeQuery(query);
stmt.close();
con.close();

I have tested that the ODBC connection can connect to the database. The sql query has been dumbed down to select '1' from dual. I have not included the word "select" in the query.
Anyone seen this before? We are in the process of uninstalling the Oracle client completely and re-installing it to see if this solves the issue. We only installed the 64 bit version of the Oracle client. I am running on Windows Enterprise 2008 R2 - 64 bit. EAS, Essbase, EIS are all 64 bit installs. I believe Studio is the only one that is 32bit. However we are not currently using this product.
Thanks,
Mike

Hi Mike,
With Oracle Support's help, we got 3 of the 5 servers working now. We were using the Datadirect drivers but were configuring them wrong! You have to use the Standard Connection portion in the setup, specifying the Host, Port Number (1521) and the SID. We were using the TNSNames Connection which worked in the past, but apparently does not now.
So I am down to 2 servers not working. They are both Windows 2008 R2 Enterprise 64 bit, running Oracle EPM Essbase 11.1.2.1. When I Open SQL in EAS it prompts for database (Essbase Server, App, DB) and when I hit ok it pops up with "Network error: Cannot Locate Connect Information For []". We did not do any of the suggestions in the document you linked to get the other 3 servers working. When you hit ok on that error, you then get another error stating, "There are no Data Sources defined. 'SQL data sources' option will be disabled". We do have datasources defined on the server.
Any ideas?
Thanks,
Mike
