JDBC and LDAP Connect to database

I am testing a little bit with jdbc thin client and how it should be setup with a ldap naming service (tnsManager). What I heard is that I need a special lib so JDBC can use the LDAP naming service but i have no clue. I have been looking around the internet but haven't really found anything. What do I need on the DB side to make it work?

Not very sure .. may JNDI be used for connection using LDAP. cause JNDI is have a support for LDAP urls.

JDBC and MySQL connectivity problem

The code i hav attached generates Connectivity exception.. the prob is with the part in bold.. can anyone help
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class testconn {
public static void main(String args[]) {
    Connection con = null;
            String serverName = "localhost:8080";
        String mydatabase = "imagedb";
        String url = "jdbc:mysql://" + serverName + "/" + mydatabase; // a JDBC url
        String username = "am";
        String password = "ta";
    try {
      Class.forName("com.mysql.jdbc.Driver");
     con= DriverManager.getConnection(url, username, password);
      if(!con.isClosed())
        System.out.println("Successfully connected to " +
          "MySQL server using TCP/IP...");
    } catch(Exception e) {
      System.err.println("Exception: " + e);
    } finally {
      try {
        if(con != null)
          con.close();
      } catch(SQLException e) {}
}

I had such issue too, and I fixed it by adding in the environment variables the CLASSPATH entry that pointed to all the directories containing the .jar needed for the applications.
for example I used jodbc folder to connect mysql database (I installed last version and I got same issue than yours and it seems to be a 'connector' issue, exactly the same issue than yours) I got something like
CLASSPATH=my root dir/the java dir/the lib dir/jodbc;my root dir/the java dir/other important libs containing .jar files;
This is what I got for the issue, still working around (at the level of mysql all is ok, ...)

Can't really understand why this code won't run anymore, ...
I took a look on the other computer where the same code is running ok.
These are the differences:
mysql server is 5.0.18 on the other computer the version is 3.23.41
mysql connector is 3.51.12 on the other computer the version is 3.0.10
access rights are the same because the database is the dumped one from 3.23.41 to 5.0.18, and I'm quite good with the dbms management (I'm IT developper in fact, trying to take over java technology ;) )
in this case this is not a sql error but java error.
the jar file is set to the %classpath% folder on both computers
I copied the jar from the other computer, removing the new .jar file and... it failed, exactly the same issue
Still working around, ...

Thank you very much.....

Hi Deep,
There is a how-to posted on SDN regarding how to connect and configure the BI JDBC Connector.
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/uuid/6209b52e-0401-0010-6a9f-d40ec3a09424
This document describes the jdbc driver to use etc.
Hope this helps,

Domino Notes and LDAP Connection using wls 6.1

We would like to use Domino LDAP for authentication/authorization in Webogic, but
we are not able to configure it. Has someone else already done this? Below is
a list of steps to take that we got from a BEA consultent. The problem is step
10, rebooting the server. When I try to do this, I get a Fatal initialization
exception error and cannot start the server.
1. Open the WebLogic Server Administration Console http://localhost:7001/console
in a browser.
2. In the right pane of the Administration Console, click the mydomain->Security->Realms->Create
a new Custom Realm.
3. Enter MyLotusLDAPRealm in the Name field.
4. Click Create.
5. In the right pane of the Administration Console, click the mydomain->Security->Caching
Realms->Create a new Caching Realm.
6. Enter MyLotusCachingRealm in the Name field.
7. Click Create.
8. In the right pane of the Administration Console, click the mydomain-Security.
9. Select the MyLotusLDAPRealm from the drop-down box for the Caching Realm.
10. Reboot the WebLogic Server.
11. Copy the ldaprealm.properties to bea/wlserver6.1
12. Modify the web.xml
13. Modify the weblogic.xml
If anyone has done this before please let me know how you did it. Thanks!

That works. Thanks!

I'm trying to create connection pool to Oracle 9i database under Linux.Oracle
installation is fine, and I can use Oracle examples to connect to mydatabase.
But when I try to create pool from within WLS I get:
- Trying oracle.jdbc.OracleDriver: <Cannot startup connection pool"oraclePool"
No suitable driver>
- Trying weblogic.jdbc.oci.Driver: java.lang.UnsatisfiedLinkError:/home/usr/local/bea/wlserver6.1/lib/linux/i686/oci816_8/libweblogicoci37.so:
libclntsh.so.8.0: cannot open shared object file: No such file ordirectory
The latter is not a surprise, since the file does not exist. InsteadI
have libclntsh.so.9.0
and vanilla so, which is a soft link to 9.0. Creating link with desiredname (libclntsh.8.0)
to 9.0 does not help as it throws on unsatisfied symbol.
Can you advise me on the reason and remedy?

SQL Developer Blocked and is not allowed to connect to database ORA-200001

SQL Developer Blocked and is not allowed to connect to database gives ORA-200001.
i found on net that DBA can write triggers which can deny connection to database from certain appplication.
so i want a way to change application name so that when it connects to database
the V$SESSION will have different value (other than SQL Developer) in column PROGRAM and/or MODULE (which i think is used by dba to restrict the connection).
one more way is
i am using jdbc url to connect to database
in java we can change properties of connection to change the PROGRAM in V$SESSION.
but i am not java expert so dont know how and where to make the changes
either way my aim is to connect to database such that V$SESSION will have different value (other than "SQL Developer") in column PROGRAM and/or MODULE

This is not system configration or credential issue.
This is a check which is put DBA using logon trigger
to check certain user loging in using certain application.
only some users using particular username are getting this error when they try to logon using oracle sql developer
the same users when uses different username(some generic user names created to access database) to access the same database then they are able to login.
similarly if they login using SQL navigator they are able to login with both their own and the generic user name
more over of all the database instances this is only happening on some of the instances and all of them are development instances.
following will help you understand
USER | DBUSERNAME | DATABASE | APPLICATION | ACTION
X | X | DB1 | Oracle Sql Developer | Blocked
X | G(Genric) | DB1 | Oracle Sql Developer | Login Success
X | X | DB1 | Sql Navigator/SqlPLus | Login Success
X | G(Genric) | DB1 | Sql Navigator/SqlPLus | Login Success
X | X | DB2 | Oracle Sql Developer | Login Success
X | G(Genric) | DB2 | Oracle Sql Developer | Login Success
X | X | DB2 | Sql Navigator/SqlPLus | Login Success
X | G(Genric) | DB2 | Sql Navigator/SqlPLus | Login Success
I just want to bypass this check which i think uses V$SESSION and columns PROGRAM and/or MODULE to check the application used by particular user.
if i can override these values some where in oracle sql developer before loging in the DB then i can clearly pass this check and login to database.

IDoc to JDBC and JDBC to IDoc Scenario

Dear All,
I am working on IDoc to JDBC and JDBC to IDoc Scenario.
I have to send Idoc from SAP to Non SAP system(.NET application) i almost configured in XI but still i don't know when my INTEGRATION will INVOKE how my data will proceed from IDOC to Oracle database(Through JDBC) and in case of revese how and when Data flow will start.
Does anyone have completed STEP by STEP scenario document for this?
How my Idoc will sent to XI?
How XI will pick up data from IDoc?
How XI will Convert data to JDBC and UPDATE in Oracle Database?
And i reverse case(JDBC to IDoc) when my INTEGRATION will INVOKE?
Where and When i can watch my process and data?
How can i test the whole integration?
I AM GETTING ERROR WHILE TESTING CONFIGURATION IN Integration Directory "Error while refreshing the XI runtime cache" and when i check this in SXI_CACHE it gives me error
"Unable to refresh cache "NO_BUSINESS_SYSTEM"
"Error during last refresh to cache"LCR_GET_OWN_BUSINESS_SYSTEM - NO_BUSINESS_SYSTEM"
Please solve all the above problems i will reward u points
thanks,

Problem in JDBC connection to database

Hi,
I m new to JDBC. I want to retrive some data from the database in my JSP page. How do i do it ??? I written a following code,
String custid = null;
String custname = null;
String custref = null;
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@<server>:1521:yoda","scott","tiger");
Statement stmt = conn.createStatement();
String strCustomer = "select customer_id from fmm_user_access where login_id = '" + username + "';";
ResultSet rset = stmt.executeQuery(strCustomer);
while (rset.next())
custid = rset.getString(1);
custref = "1."+custid;
strCustomer = "select full_name from fmm_ofin_customers where customer_ref ='"+ custref + "'";
ResultSet rset1 = stmt.executeQuery(strCustomer);
while (rset1.next())
custname = rset1.getString(1);
conn.close();
} //try
catch (Exception e) {e.getMessage();}
Are there any setup issues which i m missing, like setting some paths. Please advise.
Thanks in advance
Unmesh

Hi Unmesh,
I did not see any code in your JSP page which is printing the output of your query.
You may want to modify your JSP to display the results like this
<%@ page import="java.sql.*" %>
<HTML><BODY>
<%
strCustomer = "select full_name from fmm_ofin_customers where customer_ref ='"+ custref + "'";
ResultSet rset1 = stmt.executeQuery(strCustomer);
while (rset1.next())
custname = rset1.getString(1); %>
Customer Name is <%=custname%>
 
<% }
conn.close();
........... %>
</BODY></HTML>
And you will need to ensure that the JDBC drivers( classes12.jar or ojdbc14.jar) are in your classpath.
A couple of other observations I have about your code is
1. You must explicitly close the ResultSet and Statement objects after you finish using them: rset.close();stmt.close()
2. Try using PreparedStatements for your insert statements which allows you to define bind parameters. In your case -
PreparedStatement pstmt =
conn.prepareStatement ("select customer_id from fmm_user_access where login_id = ?");
pstmt.setString (1, userName);
You can refer to JDBC samples on OTN for more information : http://otn.oracle.com/sample_code/tech/java/sqlj_jdbc/content.html
Hope this helps.

when should you close the connection? when you're done with it.
how should you close the connection? like this: conn.close();
that said, doing this in a JSP page is bad form and not recommended
JSP's typically don't contain ANY business or data logic

Connection sharing for embedded JDBC and DatabaseController

 I would like to share an existing JDBC connection with the DatabaseController (i.e. same session in database). Basically I need to call a stored proc in the JSP page then use the same (already established and open) connection for the DatabaseController to run the report.Is that possible? If so, can you give me a brief example. I'm well versed in Java, but not at all in CR. I'm trying to help evaluate the effort to merge existing web application code with CR reports. The company has many existing CR files that I would like to "take to the web", but the underlying database uses session information and VPD for security.For reference I'm using an Oracle 10g database. I would also welcome an answer that uses connection pooling and I could simply hand out pooled connections to the DatabaseController.Thanks! 

Hi, Unfortunately there currently is no way to pass a JDBC connection to the report at runtime (this would be a great idea to track under the enhancement requests forum section). That being said there are other options you can do to get connection pooling functionality within your application. Probably the easiest way is to use JNDI. This will allow the application server to handle the Connection Pool. There is an optional property of the database connection of a report which allows the report designer to specify a JNDI lookup name. At runtime the report will look for this lookup name first prior to attempting to make the JDBC connection.You can look at this comment on another question for instructions on how to set the JNDI optional name:<a href="/node/483#comment-79">http://diamond.businessobjects.com/node/483#comment-79</a> Another option is for you to pass in a java.sql.ResultSet at runtime to the report. It sounds like you are already making a JDBC connection at runtime so it shouldn't be too difficult for you to add the SQL query statement to populate a ResultSet. Once you have the ResultSet populated you can pass it into the report. In fact the wizard which is outlined on the comment listed above has a screenshot of the wizard which will generate the code at runtime to view a report. If you select the option in the wizard to "Populate the report with a java.sql.ResultSet" it will generate the necessary code stub to demonstrate how this will work.The only downside to passing in the resultset at runtime is that it requires the entire dataset to be populated prior to passing it to the report. If the dataset is relatively small the performance impact will likely be acceptable, however if you start getting in to the tens of thousands of records then you may start seeing some performance implications. Hope this helps. Let me know if you have any follow-up questions. Regards, Sean Johnson (CR4E Product Manager)

How to connect the database (JDBC) using service name rather than SID

How should we make the connection to the database using service name. Initially, we are using the SID to make the database connection, with following setting in the data-source.xml in OC4J using ABCDB as the SID.
<data-sources>
 <data-source
 class="com.evermind.sql.DriverManagerDataSource"
 name="jdbc/ABCDB"
 location="jdbc/ABCDB"
 pooled-location="jdbc/OracleDSPooled"
 xa-location="jdbc/xa/OracleDSXA"
 connection-driver="oracle.jdbc.driver.OracleDriver"
 username="ABC"
 password="ABC"
 url="jdbc:oracle:thin:@191.1.4.126:1521:ABCDB"
 />
</data-sources>
It work, but now we need to make the connection using this service name ABCSERVICE, but it doesn't work in the OC4J (JDBC). May I know how should we handle this connection?
Thanks and Regards,
Pang

Finally, I got the solution to make the database connection using service name, with putting the tnsname setting in URL portion.
url="jdbc:oracle:thin:@(description=(address=(host=191.1.4.126)(protocol=tcp)(port=1521))(connect_data=(SERVICE_NAME = ABCSERVICE)))"
And now, it is working fine.

How to use JDBC to connect informix database

Dear all,
I want my client application to connect informix database by using JDBC. The JDBC driver has been installed successfully in the client computer (Win2000). The informix 5.0 resides the a Unix server named "dbserver". The following is my java program.
========================
import java.sql.*;
import java.awt.event.*;
public class Application1 {
public static void main(String[] args) {
Connection conn;
try
Class.forName("com.informix.jdbc.IfxDriver");
catch (Exception e)
System.out.println("Error "+e.getmessage());
e.printStackTrace();
return;
System.out.println("It is ok");
try
conn = DriverManager.getConnection("jdbc:informix-sqli://dbserver:1526:INFORMIXSERVER=dbserver;username=test;password=******");
catch (SQLException e)
System.out.println("ERROR ."+e.getMessage());
e.printStackTrace();
return;
System.out.println("All is fine");
===========================
However, the error appears mentioning "Attempt to connect to database server (dbserver) failed." I don't know what the problem is because my informix database server is exactly "dbserver".
Kindly need help from you guys. Thanks in advance.
Kevin

Hi,
Plz try this (instead of 'username' use 'user') ...
DriverManager.getConnection("jdbc:informix-sqli://dbserer:1526:INFORMIXSERVER=dbserver;user=test;password=*****");
or this (pass the username and password as params)....
DriverManager.getConnection( "jdbc:informix-sqli://dbserer:1526:INFORMIXSERVER=dbserver" , "test" , "*****" );
Hope this helps

How to connect mySQL database with jdbc

Who can tell me how to connect mySQL database with jdbc? Thanks

Not able to connect to database using jdbc

Respected sir/madam,
I am new to java and i am trying to connect to database which is necessary for me in project when i wrote the code using class.forName i am able to compile but when runnig i am getting two exceptionns one is oracle.jdbc.driver.oracledriver not found or excetion in thread main class not found please help me

Subash,
1) Please refrain from cross-posting (posting the same message into two or more forums). This question was better asked in the JDBC forum as you eventually put it but you already posted here so if that happens again next time just leave the original thread be.
2) Your compilation classpath and your runtime classpath are not related. As a matter of fact with well written JDBC code and under most conditions you should not need your driver in your compilation classpath at all, only your runtime one.
3) Your driver is not in your runtime classpath. That is the error that you need to resolve.

Installing JDBC driver to connect to Oracle 8i Database from Weblogic 10.3

I want to connect to Oracle 8i database from weblogic 10.3 application server. I found a classes12. zip file on Oracle.com to use as driver for the same.
I am also connecting Oracle 9i database from the app server. Now if i replace the classes12. jar from the lib folder won't it disallow me to connect to the Oracle 9i database.
2ndly the claases12.zip file i found from the site is for jdk 1.2 will it create any problems. Please let me know
Kindly let me know what is the standard procedure to install a new driver in Weblogic 10.3.

I tried to install weblogic 10.3 using jdk 1.5.07 but. it is not supported. Moreover from the sites also i found that it's only the application wars and ears compiled in jdk 1.5 need not be recompiled in 1.6. But no reference of jdk 1.5 is there.
I tried to use thin client from the code and connect to Oracle 7i
i got the following exception.
