Im using Netbeans and I have an error in the following codes:
dbcon= DriverManager.getConnection(url);
PreparedStatement prd = dbcon.prepareStatement("SELECT MAX(cLoan_Registration_ID) FROM loan_registration");
PreparedStatement prd = dbcon.prepareStatement("INSERT loan_registration VALUES (?,?,?,?,?,?,?,?)");
but when I execute the codes on MSDOS, it worked. I think I have a problem with my Netbeans properties. By the way im using Netbeans 3.6 and JSDK 1.4.2_04. please help.

another question is that if the database was disconnected do we have to restart all the server again.

RunMigrate.sh Java error for patch AddrBook migration to UWC
Hello All --
The MigratePab java app appears to core dump half-way through "batch" migration of PAB entries to new UWC AB Server.
/tmp/migrate.log to shows the pabMigrate finds all users for domain and correctly constructs new AB entry for o=piserverdb, and correctly updates user object in Directory (ie. all users have correct 'psroot' attribute added to user object).
Then -- apparently when actual data migration supposed to happen (ie. the MigratePab.run method -- the app throws Java exception (see below).
Note: this pabMigrate utility appears to be very "bleeding edge" (read that: "not ready for prime time") -- any ideas where more recent version of pabMigrate code resides??
Note2: each "Thread" below corrsponds to separate connection to Directory.
Thanks --GA

I am using Oracle 9i in Windows 2000. I have created a new db called DTSDB. And I have used the following program for getting connection
code:

Can you connect with SQL*Plus to your database instance ?
If no, what are the errors message do you get ?
Did you have a look to the Oracle Net Services Administrator's Guide relevant section. -
Programmatically connecting to BI server
Hi,
I have to connect to the BI server using JDBC to run BI query.
Connection details (BIAnalytics)
ConnectionType: BI (JDBC)
Username: <private>
Password: <private>
BI Host: <private>
BI port: 9703
I am using the following code to get this connection from data source
Object obj = ADFContext.getCurrent().getConnectionsContext().lookup("TMBISrvConn");
if (obj instanceof DatabaseProvider) {
DatabaseProvider BIDB = (DatabaseProvider)obj;
String userName = BIDB.getProperty(DatabaseProvider.USERNAME_CLASS_REFTYPE);
String password = BIDB.getProperty(DatabaseProvider.PASSWORD_CLASS_REFTYPE);
String hostName = BIDB.getProperty(DatabaseProvider.HOSTNAME_CLASS_REFTYPE);
String port = BIDB.getProperty(DatabaseProvider.PORT_CLASS_REFTYPE);
String connString = "jdbc:oraclebi://"+ hostName + ":" + port + "/user=" + userName + ";password=" + password + ";Catalog=";
Connection con = BIDB.getConnection();
Error: "Unrecognized JDBC URL subtype: BI_JDBC"
I tried using Driver manager
String connString = "jdbc:oraclebi://"+ hostName + ":" + port + "/user=" + userName + ";password=" + password + ";Catalog="; Class bclass = Class.forName("oracle.bi.jdbc.AnaJdbcDriver");
Connection connection = DriverManager.getConnection(connString);
Error: "cannot find suitable driver"
ThanksI am able to get this working by installing MS sqljdbc4 on weblogic and specifying the readonly parameter.

Tomcat 5 con pool, Oracle, servlet error on Connection ocon = ds.getConnect
Hello,
I am trying to create a connection pool to my Oracle db using the documentation provided for
Tomcat 5. In the servlet shown below, the servlet fails at this line:
Connection ocon = ds.getConnection();
The servlet stops with no error message. Also, I'm not sure what is supposed to go in
this line:
Context envContext = (Context)initContext.lookup("java:/comp/env");
which may be where the real problem begins. Any suggestions are greatly appreciated.
Here is the servlet:

DataSource ds = (DataSource)envContext.lookup("jdbc/CraigsList");
Connection ocon = ds.getConnection();
String sql = "select formtitle from checkboxforms where cbformid = 157";
PreparedStatement pStmt = ocon.prepareStatement(sql);
ResultSet rs1 = pStmt.executeQuery();
rs1.next();

XA error: XAER_RMERR on getConnection()

"jdbc:oracle:thin:@url:1521:PINDB","jvikas","jvikas123");
followin error is coming ... during execution.. i have included class path for driver etc..
exception in main thread .. java.lang.NoclassFoundError : java/sql/Savepoint..
at java.lang.classLoader.defineclass0<native0 method >
at java.lang.classLoader.defineclass0<Unknown Source >
plz tell what's the error is .
thanks in advance
Vikaswe need more info. what does "during execution" mean? a specific sql query? specific JDBC code? are you using JDK 1.4? if not, you have to use the JDK 1.2/1.3 compatible JDBC driver from ORACLE because the interface Savepoint was introduced in JDK 1.4.

Error in DataSource.getConnection() !
Hello to u all,
I'm trying to make an application that uses database connection pooling and i've followed
closely the tutorial:
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/printer/jndi-datasource-examples-howto.html
The code in the tutorial worked just fine, however, later when i tried to use it in my (servlet)application a get an error in the datasource.getconnection! Here's my code:

</web-app>
I know that the configuration in the server.xml is fine because the example in the tutorial worked!!
so my code in the doPost method in the servlet is:
Context initCtx = new InitialContext();
DebugUtility.println("POST 2 ");
DataSource dataSource = (DataSource)initCtx.lookup("java:comp/env/jdbc/TestDB");
DebugUtility.println("POST 3 ");
Connection con = dataSource.getConnection();
DebugUtility.println("POST 4");
it fails in getconnection with the following error:
Cannot create JDBC driver of class '' for connect URL 'null'
can anyone figure it out what is happening ? Is my web.xml with a wrong configuration !!
thx in advance to all of u !Finally i have discover the error !!!
In fact the error reports some irony cause i had said with conviction that
the error wasn't in the server.xml , but it was :
<Context path="/contactos_sb" docBase="contactos_sb"
debug="5" reloadable="true" crossContext="true">
i was keeping the tutorial path and not my application path so my servlet wasn't able
to get the class driver and the url !!
So. it works fine now ! :)� -

GetConnection-- Network Adaptor Error
Hello there
I am running many client thread calling methods in EJB beans. I get Network Adaptor Error when trying to get connection. This only happens when many clients running concurrently.
I wonder whether other people have come accross the same problem.
If this is a driver's bug, will it be fixed soon?
Thanks,

Thread DataSources & Database getConnection timeout error
I'm usig pool connections in the application for database access.
At the moment i have max number of pool connections set to 1.
I'm using Oracle JDBC driver 10.2.0.1.0 and Oracle9i Enterprise Edition Release 9.2.0.5.0 - 64bit Production With the Partitioning option JServer Release 9.2.0.5.0 - Production.
Running JRE/SDK 1.4.2
WAS6, Rational 6.0.0
I'm trying to get the connection inside a thread but I get this exception:
J2CA0045E: The connection is not available when you invoke the method createOrWaitForConnection for the resource jdbc/DBDS
and then this: Connection not available, Timed out waiting for 10000
The function in the main class is like:
PrT cnxT=new PrT(); Thread hilo=new Thread(cnxT, "cnxT"); hilo.start();
the runnable class is like:
public class PrT implements Runnable { public PrT(){ super(); } public void run(){ try{ InitialContext ic = new InitialContext(); DataSource ds = (DataSource) ic.lookup("jdbc/DBDS"); Connection con=ds.getConnection(); /** here my sql sentences **/ con.close(); } catch(Exception e){ } } }
If I change the max number of pool connections to 2 this executes pretty well and if I change the code and make the connection outside the runnable class there's no problem. But I need to make a new connection inside the runnable class because I'm gonna run multiple threads at once.
Why do I need to put the max connections pool in 2 if there're not connections opened?
What should I do to open the connection inside the thread?
Sorry for my english, is not my native language.
I'll appreciate any help.

Error in getConnection() of Dataource
Hi,
I am using the datasource for connecting to the database.
When I use the getConnection() method of DataSource without any parameters then it gets executed correctly .
But the problem is that I cannot use the method getConnection() without
parameters. I need to use the method getConnection(String username,String password);
When I use this method it throws UnsupportedOperationException.
Can any one help me in solving this problem.
