Problem in establishing connection from MQSeries to Weblogic 7

          Hello,
          I was earlier having a connection established between MQSeries and Weblogic 6.1,
          that is working fine but recently I have upgraded to Weblogic 7.1
          Now when I try to have a connection between the MQSeries and the Weblogic 7.1
          then while establishing the connection it brings down the Weblogic server i.e.
          shuts it down. I am unable to track this problem. Please if any one has ever experienced
          similar type of problem or has a solution for this problem then let me know.
          Thanks in advance.
          JJ

Hi,
I guess the problem is due to the driver class not being part of the classpath in your web application. You should include the jar containing the driver class in your classpath. Please consult the documentation provided for your web server to do the same.

Bhushan.

Problem in establishing connection with mysql 5.0

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
113,ii,25,RETAIL
114,jj,26,IT
Database table: employee
eno,ename,eage,edept
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

Connecting from VB to Weblogic

Can Anyone give me the details of how to connect from VB to Weblogic?.
Thanks

There is the documentation on this in version 5.1. Look at the WebLogic COM
integration. You might also want to look at a product called Jintegra, from
Linar.com.

Having problems sharing internet Connection from Macbook to Vonage Adapter

Hello,
I just got my Vonage adaptor and I am trying to share the Internet connection from my Macbook Pro (10.7.3) to the Adaptor to use the Vonage service bc my router is downstairs.
I turned off my Firewall, hooked my Vonage adapter to the Macbook with the ethernet cable and then went to Sys Preferences > Sharing > Selected Internet Sharing > Share Connection from Wifi to computers using Ethernet, and it looks like everything is ok but when i try to use the phone which is connected to to Vonage Adapter, it says "Your Vonage device cannot connect to the internet, check to see if your high speed internet is down".
I went and looked at my Network preferences and it shows Ethernet connected which is the Vonage Adapter and gives the following:
IP Address: 169.254.163.167
Subnet Mask: 255.255.0.0
Is there something Im doing wrong? Ive seen on several forums that its possible to do but having bad luck. Any help is appreciated.

All I know is that I got Ubuntu to share internet and offer IPs through DHCP by using Firestarter. I am very new to Solaris, however, and am looking forward to learning about it. I've just made it my regular desktop environment. Long as you can get Solaris to configure its network interface with DHCP after your Ubuntu is configured, you should be able to share to as many clients as you'd like. Fedora also works well for that, and in my opinion, it's a better Linux than Ubuntu, though Solaris remains a better Linux than Linux, right? Har.

Problem to establish connection what the wrong with this

dears
i want to access the oracle database without ODBC bridge.
i dowload the thin driver from Oracle site.
1.ojdbc14.jar is in my claspath.
2.actually i do the following i have oracle 8.0 for winnt.
go to system manager and create user "administrator" after this give grants dba to that user.
now my code is as under
import java.sql.*;
public class LoadDriveroracleuser
public Connection conn=null;
public LoadDriveroracleuser()
try{
Class.forName("oracle.jdbc.driver.OracleDriver");
conn=DriverManager.getConnection("jdbc:oracle:thin:@host:1521:database","administrator","allah");
}catch(Exception ex){
MyOptionPane.MyErrorMessage(null,ex.getMessage());
System.exit(0);
}//end of constructor
}//end of classthe exception is occur that// network adapter not established the connection.
actually i am not knowing that host:1521:database how set these .
i have standalone application.not using the server.
plz guide me i am very thankful to u

If Oracle is set up properly he should be able to
connect using JDBC without having the client installed
or any TNS names set. The JDBC driver alone is
sufficient.
It wouldn't be a bad idea to follow this suggestion,
but it's not necessary for JDBC's sake.
%Yeah of course it's not necessary for JDBC - it would just allow him to ascertain whether SQLplus works.
Somehow i've a sneaky feeling that this 'database' that's being used to connect is just a marker/plain english instead of the actual name of the database :)

. 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.

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

Problems in SQL Connection from Java program to Oracle 8.1.7

Hi,
I am java program that connects to Oracle 8.1.7 .
Client: java code on Windows 2000
Server: oracle 8.1.7 on Solaris
Java code uses two types of Connection Pools. One Pool uses "thin" connections and other pool uses "OracleConnectionPoolDataSource" class.
The methods which use "thin" pool work great however the methods which use "OracleConnectionPoolDataSource" fail after 5 to 10 calls.

Help please! Problem accessing db connections from servlets

Hi all,
I am creating a web application using MVC architecture using jsp,servlets and beans.
I have created a login.jsp which accesses the LoginHandlerServlet.class.
in login.jsp there are two fields. One is username and one is password. When fields are filled and submitted it redirects it to LoginHandlerServlet. Now in the servlet it calls a passwordBean which in turn calls a connectionBean which gives the connection to passwordBean and passwordBean checks the username and password and returns the result to servlet.
Now when I run this application through tomcat. I am getting a error
Error : oracle:jdbc:Driver:OracleDriver
But when I append a main method in passwordBean which calls the corresponding method my driver gets initialised and I get the perfect output.
Please let me know what is wrong with this. Thanking you all in advance.

Problem in getting the database connection from a connection pool

Hai All,
I am facing a problem in getting the database connection from a connection pool created on weblogic server 8.1.
I am using the Oracle database 8.1.7.
I have configured my connection pool, datasource and JNDI in weblogic.
In my java program i have the following code to retrieve the connection.
import java.sql.*;
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
class jdbcshp1 {
    public static void main(String[] args) {
     Connection connection = null;
     try {
           Hashtable ht = new Hashtable();
           ht.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory"); // Wanna get rid of this.
           ht.put(Context.PROVIDER_URL,"t3://localhost:7001"); // wanna get rid of this.
           // Get a context for the JNDI look up
           Context ctx = new InitialContext(ht);
        javax.sql.DataSource ds = (javax.sql.DataSource) ctx.lookup ("myjndi1");
          //Create a connection object
          connection = ds.getConnection();
     The above code is working fine but, the two ht.put statements are creating problem.
The problem is, after converting the application into WAR file it can be deployed
on any machine or different port on same machine. My application fails if its deployed on
weglogicserver which is at different port.
Is there any way that i can get rid of those ht.put statements or any other way to solve the problem.
any help is appreciated.
Thanks in advance
Pooja.

Hai All,
Firstly, thanks for ur reply.
Even i have seen some code which uses context constructor with out any parameter and works fine.
i dont understand why its not working for my code.
When i remove those ht.put code and use context constructor with out any parameter, it giving an error.
Context ctx = new InitialContext();
javax.sql.DataSource ds = (javax.sql.DataSource) ctx.lookup ("ocjndi");
connection = ds.getConnection();The error is as follows:
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
the above error is forcing me to include those code but if the port number is changed the code will not work. Plz let meknow if some setting have to be made.
I appreciate all ur valuable help.
Thanks once again.
Pooja.
