Help on Jdbc dynamic connection

I am trying to create a dynamic pool with oracle where I am picking the poolname from the JNDI context and setting the connection properties but I am getting authorazition error even though I added user scott in connectionpoolcreate of weblogic6.1can any one suggest me to solve this problem

Hi ...
I didn't get any reply from any one....
Is it possible to make Java Server Pages and RMI work together -
to invoke a method on a server object from a JSP? And if, does
someone know of a good tutorial, article etc., on this matter?
waiting for ur reply!!!!

Dynamic Connection Pool Creation Failing in a cluster

Hi,
I am trying to create a connection pool in a clustered environment. This connection
pool is created lazily behind a Stateless Session Bean. We first attempt to determine
whether, the connection pool exists using JdbcServices.poolExists(someName), and
create it if it does not exist. A failure occurs on creation because it looks
like the connection pool might have been created by a bean on a different weblogic
VM instance. Is there any way to dynamically create a connection pool and make
it visible to the whole cluster? Thanks in advance for any help. Michael Dolbear

The only way to do it is using MBeans. You could search this newsgroup
for "JDBCConnectionPoolMBean" to get an idea of how it could be done.

Slava,
I am working with Mike on this issue and wanted to add some moreclarifications.
We have a two server cluster where one of the EJB's on one of the Managedservers
creates the connection pool. The problem comes in when a request comes tothe
second server in the cluster. The connection pool is created by the firstserver
but it is only assigned to the first server in the targets section on theconsole.
It isn't assigned to the cluster. Is there a way to programmaticallyassign the
pool to the cluster instead of just the server that created the pool?

Hi Michael,
Could you show us the code? Without looking at the code
I can only say that JdbcServices.poolExists(someName)
returns true only in case the pool is up and running.
If the connection pool MBean was created but not assigned
a target, subsequent tries to create it would fail.

Jdbc dynamic credentials

How does one go about implementing JDBC dynamic credentials as suggested by this article http://otn.oracle.com/products/jdev/howtos/bc4j/howto_dynamic_jdbc.html in UIX instead of JSP? Any pointers?
Thanks!
Ronny

I should preface this with a warning that I'm not all that familiar with what you are trying to do. However, it should be possible to use very similar code to what is shown in the How To document for JSPs. In the JSP example, the code is inline part of the JSP. uiXML doesn't mix code and UI, so this code would therefore be located in a method event handler.
The first thing to do would be to create a uiXML page with form fields for username and password. I would use a messageTextInput for these fields (with the secret attribute set to true for the password field). I would add a "Login" submitButton, and then add a ctrl:event="Login" attribute to the button so that it will fire a UIX Controller "Login" event.
I would add a handler for the "Login" event in the handlers section of the uiXML page, and use a method event handler to call out to Java code. The method event handler has access to the HTTPSession and the submitted username and password, so you should be able to get the HTTPContainer and manipulate the session. The only major difference with the JSP example, would be that the JSP example uses the <jbo:ApplicationModule> tag in a try/catch block to attempt the connection, and you would need to use the regular BC4J Java APIs. If the connection was sucessful, your event hander would return an EventResult for the next paeg in your application, if there was an error you could return an event result for the same page displaying the error (as discussed in the Handling Errors chapter of the UIX Developer's Guide).
Whenever discussing login procedures, it is worth pointing out the TrivialPageFlowEngine in the UIX Controller which is useful in enforcing that the user has gone through your login procedure prior to jumping to any page in the application.
Hope this helps!

How to use one dynamic connection managers for multiple parallel data flow tasks

hi there:
I have 6 databases residing on the same server. What I want to do is call a store procedure with identical name on each database dbo schema and transport results to a centralized place. The key is to have those SPs run in parallel instead
of in sequence as each SP may take around 10 mins to finish.
The simplest way is to create 6 OLE DB connection managers and create 6 DFT tasks. However, I do not want to maintain 6 OLE DB connection managers as there is a chance to have more connection managers.
What I did so far is to create a OLD DB connection manager and use expression to set up connectionString properties so that it will get populated by variables at run time. It is fine when running all SPs in a Foreach Loop Container. However, it takes
around 60 mins to finish.
When I try to run it in parallel ( basically created 6 DFTs but use only one Dynamic Connection Manager), the connection string gets confused therefore all DFT tasks failed.
Does anyone here have some experience on this topic?
Thanks
hui

Yes, basically, on the connectionString property of ONE OLEDB, you are using an expression to supply value and this expression is pointing to a variable.
In this case , you can update this variable from a table which contains many connection strings. It's good if you want to execute Store procedures in a sequential order. When in parallel mode, this will cause issues as connectionString gets overwritten.
I am thinking about using script task to exec sp.
The whole idea is that I do not want to maintain a large number of Connection Managers.
Hope it helps
--Currently using Reporting Service 2000; Visual Studio .NET 2003; Visual Source Safe SSIS 2008 SSAS 2008, SVN --
So you are not able to run parallel executions using same conn mgmr, even with dynamic connectionstring, is that correct? Yes, script task will be a way to go if you wish to execute it in parallel, you may connect to SS and query the proper conn string with
SELECT/WHERE clause in each script > pass it to a script variable > use that script variable and execute the proc. This will require only two things to change in each script, the WHERE condition to get the conn string and the proc name (you may even
get the proc names the same way you get conn string) and everything else will be same. Let us know how that goes.
Hope no two or more procs doing insert/update/delete on the same tables.

Serious problem of jdbc-mysql connectivity using tomcat

hi everybody
i m in serious problem since last 15-20 days. i m trying hard to make the connection jdbc-mysql using tomcat with the help of a jsp test page but every time i am facing almost the similar probems listed below in detail:
to make sure that the jdrivers's .jar (mysql-connector-java-3.1.7-bin.jar) available for such connections working fine i have tried the above said connection without using tomcat....which is working fine...for this i have created a dummy database with a dummy table ..and written some queries in the .java file of my code which upon running inserts the specified values in the defined(dummy) database.
this is the confirmation that the classpath etc..are ok in regard to the mysql-connector-java-3.1.7-bin.jar
now i have placed a copy of this .jar file in to the commons/lib directory of the tomcat web server(which is suppossed to be the place for such external jars)
after doing so i have followed 2 methods :
method 1st:........
i have made aone more jar file from the following .java file....
import javax.naming.*;
import javax.sql.*;
import java.sql.*;
public class TestSQLLoad
String user = "Not Connected";
String pwd = "no pwd";
int id = -1;
public void init() {
try{
Context ctx = new InitialContext();
if(ctx == null ) {
throw new Exception("Boom - No Context");
DataSource ds = (DataSource)ctx.lookup("java:comp/env/jdbc/TestDB");
if (ds != null) {
Connection conn = ds.getConnection();
if(conn != null) {
user = "Got Connection "+conn.toString();
Statement stmt = conn.createStatement();
String q = "select name, password, id from user";
ResultSet rst = stmt.executeQuery(q);
if(rst.next()) {
user=rst.getString(1);
pwd=rst.getString(2);
id = rst.getInt(3);
conn.close();
}catch(Exception e) {
e.printStackTrace();
public String getUser() {
return user;
public String getPassword() {
return pwd;
public int getID()
return id;
after compiling it at the cmd prompt i made a .jar file from the .class of it and named it MySQLLoad.jar...then i placed it also in to the commons/lib directory where the mysql-connector-java-3.1.7-bin.jar was already placed.
then i have changed the server.xml and web.xml files from the conf directory of the tomcat as given here:
server.xml

</web-app>
after all this i have taken a jsp page whose code is here:
(the mysql database used is named as "testdb" and the table name is "user" which is having fields name,password and id)
<html>
<head>
<title>DB Test</title>
</head>
<body>
<%
TestSQLLoad tst = new TestSQLLoad ( );
tst.init();
%>
<h2>Results</h2>
User <%= tst.getUser() %>
Pwd <%= tst.getPassword() %>
Id <%= tst.getID() %>
</body>
</html>
and placed it in to the Tomcat 5.5\webapps\tomcat-docs\testdb directory and saved as test-db.jsp
when i run this page on the browser i get a lot may errors stating
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 12 in the jsp file: /testdb/test-db.jsp
Generated servlet error:

javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
note The full stack trace of the root cause is available in the Apache Tomcat/5.5.4 logs.
AND NOW WHEN just to get rid of such errords i try to include a statement
<%@ page import="pkg.TestSQLLoad" %> in the jsp page code (and also place the MySQLLoad.class file in a folder called pkg and place it in the same directory where the jsp page is )and make it look like
<html>
<head>
<%@ page import="pkg.TestSQLLoad" %>
<title>DB Test</title>
</head>
<body>
<%
TestSQLLoad tst = new TestSQLLoad ( );
tst.init();
%>
<h2>Results</h2>
User <%= tst.getUser() %>
Pwd <%= tst.getPassword() %>
Id <%= tst.getID() %>
</body>
</html>
now when i run it i get the following errors:
exception

in response to the above error i have even tried placing the MySQLLoad.class directly in the testdb folder along with the jsp page without keeping it in a package named pkg and then importing directly as <@page import="MySQLLoad" %>
that too gave me the following errors

and if i do not use the statement <%@ page import="MySQLLoad"%> then also i get the errors like

THE 2nd Method:
in my second method i did the same changes in the web.xml and server.xml
then i took a jsp page with the following code:
<%@ page import="javax.sql.*,java.sql.*,javax.naming.*,com.mysql.jdbc.*" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<TITLE> trial doc </TITLE>

<BODY>
<h1>Trial Document</h1>
<% InitialContext context=new InitialContext( );
DataSource dataSource=(DataSource) context.lookup("java:comp/env/jdbc/testdb");
Connection conn=dataSource.getConnection();
Statement stmt=conn.createStatement();
ResultSet rset=stmt.executeQuery("select * from user");
if (rset.next()){
%>
<table width="100%" border="1">
<tr align="left">
<th>name</th> <th>password</th><th>id</th>
</tr>
<%
do {
%>
<tr><td> <%=rset.getString(1)%> </td>
<td><%=rset.getString(2) %></td>
<td><%=rset.getString(3) %></td></tr>
<%
} while (rset.next());
%>
</table>
<%
} else{
%>
No results from query
<%
rset.close();
stmt.close();
conn.close();
context.close();
%>

thanx for ur response
as u said that the problem is more of a jsp page not getting compiled....
me also pointed towards the similar situation providing all the surrounding situations
which i have met and gone through
i m still thinking that problem may b in the tomcat's server.xml and web.xml as well
so better if u plz guide me in that regard
regards,

Dynamic connection string not working in SSIS package 2008R2

I am using SSIS package for Import data from excel sheet to SQL DB. In the configuration file I'm using following variables.
Name scope DataType Value
DBName package String DB_Master
Password package String xx
UserName package String sa
ServerName package String xxx.xxx.x.xx
SqlConnectionString package String DataSource=xxx.xxx.x.xxx;UserID=sa;Provider=SQLNCLI10.1;Integrated Security=SSPI;Auto Translate=False;Initial Catalog=DB_Master;Password=xx
Right click OLEDB ConnectionManager then click properties window below values assign
ConnectionString - Initial Catalog=DB_Master;DataSource=xxx.xxx.x.xxx;UserID=sa;Provider=SQLNCLI10.1;Integrated Security=SSPI;Auto Translate=False;
DelayValidation - True
Expressions -ConnectionString - @[User::SqlConnectionString]
In SqlConnectionString variable properties window below values assign
EvaluateAsExpression -True
Expression -"DataSource=" + @[User::ServerName] + ";UserID=" + @[User::UserName] + ";Provider=SQLNCLI10.1;Integrated Security=SSPI;Auto Translate=False;Initial Catalog=" + @[User::DBName] + ";Password=" + @[User::Password]
After deploy the package file I change the DBName in SqlConnectionString DB_Master to Master but package execute the files in DB_Master.
and also if i give invalid ServerName like 198.152.1 but package executed successfully.
Please tell me where i made mistake. what's goes wrong...?
I just use variable like below link
https://anothersqlgeek.wordpress.com/2013/03/28/ssis-dynamic-connections-part-1/comment-page-1/#comment-48

First see whether you've some other configurations also set inside the package for the same properties? ie direct configuration for connection manager properties.
Secondly see if its executed from a job and you're overriding the values through the job properties.

A bug in creator when creating jdbc jndi connection

Hi,
I am using sun java studio creator for jdbc jndi connection. The syntax is
Context ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("java:comp/env/jdbc/mydb");
conn = ds.getConnection();
It's failed. Once I change to ctx.lookup("jdbc/mydb") and the connection is created.
Once deployed to tomcat, it seems only java:comp/env/jdbc/mydb is working.
The full path(java:comp/env/jdbc/mydb) seems right from my google search.
Why creator using jdbc/mydb? Is it a bug to creator?
Thanks,
Jie

I mean a resource reference in web.xml file that looks like this:
     <resource-ref id="ResourceRef_1103225373500">
          <res-ref-name>DBConnection</res-ref-name>
          <res-type>javax.sql.DataSource</res-type>
          <res-auth>Application</res-auth>
          <res-sharing-scope>Shareable</res-sharing-scope>
     </resource-ref>
where DBConnection is the resource alias I mentioned before:
DataSource ds = (DataSource)ctx.lookup("java:comp/env/DBConnection");
Using WebSphere a binding between this above defined ResourceRef and JNDI mapping must be defined in a file called ibm-web-bnd.xmi. The content of this file will look like this:
<?xml version="1.0" encoding="UTF-8"?>
<webappbnd:WebAppBinding xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:webappbnd="webappbnd.xmi" xmi:id="WebAppBinding_1" virtualHostName="default_host">
<webapp href="WEB-INF/web.xml#WebApp"/>
<resRefBindings xmi:id="ResourceRefBinding_1103225373500" jndiName="jdbc/mydb">
<bindingResourceRef href="WEB-INF/web.xml#ResourceRef_1103225373500"/>
</resRefBindings>
</webappbnd:WebAppBinding>
Obviously using WSAD all of that could be done using IDE. In your case and using Sun IDE, I am not sure. But this is basically the concept of needed mapping in order to reference your JNDI without getting an error. At least this is how we resolved the error you are encountering.
Hope that helps!

How to configure jdbc/jndi connection in crystal report 10

Post Author: effy
CA Forum: Data Connectivity and SQL
i have tried to configure jdbc/jndi connection , i have both
drivers data base side and crystal report side but i
can't configure it. so please help if u know
something.

Sorry, but I'm not on a home pc, I'm working on a virtualized pc with a long chain of permissions ... so I cannot simply download and run an utility...
Instead... I think (I WAS thinking) someone from SAP can tell me this info ... Probably I'll buy a paid assistance ticket... But really it's a strange thing that a simply connection from a (so) paid software need a so difficult problem solving routine..
I edited my environment variales: JAVA, PATH; CLASSPATH; JAVA_DIR, and a long list of others ... to ALL point to ALL of directory containing used jars...
.. I asked my SysAdmin to edit CrConfig.xml and it's done ... classpath are rights, jdbc infos are also ok, ...
.. but none ...

Destroying connection that is not valid, due to the following exception [com.microsoft.sqlserver.jdbc.SQLServerException: Connection reset]

Hi everyone,
I'm facing the following problem in a Server runing Linux with JBoss AS 4.2.2, JRE 1.6, and MSSQL Server 2005 with JDBC 2.0 (sqljdbc4.jar).
The thing is: on friday morning I started up the server and everything worked fine ... next, from Friday at 6pm to Saturday at 8am nobody has used the system.
Then on Saturday at 8:05 got the following warning lines every time I tried to do something in my application. While it seems that everything works, after a few days the system starts to decrease their performance and malfunction, so I want to know why it
might happen these warnings.
I have tried to find a solution to this problem in several places but I'm not succeeding. That's why I'm writing my problem here...
Hope somebody can help me!
Thanks in advance and best regards!
Cristian.

I´m facing similar problem with Linux and SQL Server 2008 R2. I made the downgrade of JDK 1.6 from 27 to 26 (some people reporting errors when upgraded to jdk1.6_29 and rolling back is ok) but for me the error persists. At this moment we are testing with
sqljdbc4.jar version 4.0 (released in 3/6/2012). The curious I have two equals Linux boxes and only one have presented connection reset errors.

How to create dynamic connection string with variables using ssis.

Hello,
Can anyone let me know on how to create dynamic connection string with variables using ssis?
Any help would be appreciated.

Hi vinay9738,
According to your description, you want to connect multiple database from multiple servers using dynamic connection.
If in this case, we can create a Table in our local database (whatever DB we want) and load all the connection strings. We can use Execute SQL Task to query all the connection strings and store the result-set in a variable of object type in SSIS package.
Then use ForEach Loop container to shred the content of the object variable and iterate through each of the connection strings. And then Place an Execute SQL task inside ForEach Loop container with the SQL statements we have to run in all the DB instances.
For more details, please refer to the following blog:
http://sql-developers.blogspot.kr/2010/07/dynamic-database-connection-using-ssis.html
If there are any other questions, please feel free to let me know.

JDBC MSSQL connection trouble

Hi,
I am trying to source a resultSet to a (SAP)Table in NWDS.
This is my code:
IPrivateTableContentComponentView.IVerticalGroupElement element = node.createVerticalGroupElement();
     try{
     InitialContext initialContext = new InitialContext();
     DataSource dataSource = (DataSource)initialContext.lookup("jdbc/MyAlias");
     Connection connection = dataSource.getConnection();
     Statement stmt = connection.createStatement();
     ResultSet rs = stmt.executeQuery("select * from DEP");
     while (rs.next()){
          node.addElement(element);
          element.setKeyToSelect(rs.getString(1));
     catch(SQLException e){
     System.out.println(e.getMessage());
     catch(NamingException e){
     System.out.println(e.getMessage());
I have used Radiobuttons as TableCellEditors.
I have tried many methods for connecting the driver, in this example I connected the driver at VA on server.
The trouble is I don't get any errors, I just don't get any results from the query in to the table.
Any thoughts?
Regards,
Simon

Hi Simon,
possibly the following hints can help you to find out if it is actually the database access that is not working in your application:
1.
Please view our "getting started with relational persistence" tutorial: http://help.sap.com/saphelp_nw04s/helpdata/en/91/ccbf560ecc4e2fb99b09a5e7bce95e/frameset.htm
demonstrating accessing table data with JDBC. You find the code of the example as the file J2EE_GettingStartedOpenSQL.zip
in the "examples" folder of your Developer studio installation.
2. you can view the system log of the server, for example using the Visual Administrator tool, go to the service LogViewer
3. What are the results of debugging of the component in question? Debugging is a very good method to find out quick what data has been transferred to your application (and what happens in the following)
4. some comments to your jdbc code template:
- best you close all jdbc resources (result sets, connections, statements) explicit, namely in the finally clause
- it is not a good idea to write "select *". Better name columns you read "select colA, colB"
If you use "select *" always use the
getXXX(String columnname) result set method
Please view the corresponding documentation:
http://help.sap.com/saphelp_nw04s/helpdata/en/ba/e7a1c1bc208c4bbb41b0bd20b066db/frameset.htm
Good luck
Katharina

[SOLVED]JDBC Dynamic credentials problem

Hello everyone. I have been trying to implement Steve Muench example 14 about JDBC Dynamic Credentials on my own web app., I am using Jdeveloper 10.1.3.2 and JSF/ADF.
The thing is that the JDBC dynamic credential works well but when I enter a non-existant username/password the login.jsp page sends me to the main.jsp page and in the table that I have placed there (in the main.jsp page) it shows "Access Denied". Is there any way to tell the app. to redirect the users to the login.jsp page if they try to acces other parts of the app. and they are not logged in???, or is it thay I am missing something from the Steve Muench's example???
I have been cheking the "DynamicJDBCBindingFilter.java" code and, if I understand correctly ('cause I consider myself a newbe), the "super.doFilter(request, response,chain)" is suppoused to throw an exception if the authentication fails and the "catch" code then sends the user to the login.jsp page... but for some reason this doesn't work!!!
Can anybody help me on this one please?
Thanks.
* By the way, no errors are thrown!

Hi Frank, thanks for your response. That same idea crossed my mind but the thing is that the line "super.doFilter(request, response,chain);" is supouseded to throw an exception if it fails to do its job but for some reason it does not... I have placed a "System.out.printline("XXX");" line inmediatly after the "catch" statement to see if an exception is thrown but apparently it doesn't, so I can't set a flag if I don't know for sure if the process ended well (or wrong).
I think I'll clear my mind for 1 hour and start all over again... maybe I am missing something...

JDBC Thin Connections with SSL and client certificates

Hi ,
we are going have a look at JDBC Thin Connections with SSL and client certificates.
I have two questions:
1. Is it possible to use SSL connections from JDBC Thin Driver and which release of the driver introduced it
2. Is it possible to use client certificates with JDBC Thin Driver and which release of the driver introduced it
Thanks for your help
regards
Markus Reichert

I could not reproduce the error after appending the SSL certificate to the certdb.txt file available under $Jinitiator_Home/lib/security folder.
Steps to add the SSL Certificate:
1. Run the form with the https mode in the IE Browser.
2. Security Alert is raised.
3. Click on the View Certificate button.
4. In the Certificate Window, click on the Details tab.
5. Click on the Copy to File button to copy the certificate.
6. Copy the certificate and append to the certdb.txt file.
