Can't we pass java.sql.Connection as parameter toDatum() method

I am in mid of java 1.3 to 1.4 migration, now I am getting the below error.can't we pass java.sql.Connection as a param to toDatum(), but I did the same before for another module and it worked fine, now I am getting the error.
any changes need to be done?
[b]toDatum(oracle.jdbc.driver.OracleConnection,java.lang.String) in oracle.jpub.runtime.MutableArray cannot be applied to (java.sql.Connection,java.lang.String)
return array.toDatum(c, SQL_NAME);
^
1 error
I changed to use
import oracle.sql.ORAData;
import oracle.sql.ORADataFactory;
instead of
import oracle.sql.CustomDatum;
import oracle.sql.CustomDatumFactory;

In general, it's bad practice to be that "open" with regards to parameters to methods, especially when using remote invocations. However, if you really, really, really, really need to - and I doubt you do - you can use Serializable for the type of parameter. But that's still inelegant and, well, raises all sorts of issues, starting with your design...

What is the recommended way to get a java.sql.Connection to the DB for ADF

How do I create a standalone database connection based on the datasource setup in ADF?
I have seen code like this in a method of AppModuleImpl.java but that seems a bit of a hack.
Connection conn = this.getDBTransaction().createStatement(0).getConnection();
What I need is a java.sql.Connection to the database used in the application module so I can call PL/SQL code and or work with AQ queues.
I would prefer a separate connection from the one used by the ADF model so it can have its own transaction control etc.
But I would like to get the connection created authenticated based on regular datasource setup.

How to check whether java.sql.Connection has been dropped or not

Hi,
How can i check whether the connection is dropped from the database or not by using java.sql.Connection API.
Thanks

There's a few ways to check Connections, each with a different use:
(1) conn.isOpen()
(2) conn == null
(3) the last one is a little more involved and adds some overhead. You can run SELECT 1 FROM dual; (Oracle) or SELECT 1 (MSSQL) and check for exceptions.
The only way to check a connection, as far as I know, is to use it. That said, there must be a better way???

Java.sql.Connection x J9 VM

Is possible to use class java.util.Connection with J9 VM using CDC/PP ?

Help me please;
Thanks

Is possible to use class java.util.Connection with J9 VM using CDC/PP ?Yes. Check your classpath JARs for java.sql.Connection. You may be missing the jar "database_enabler.jar". See:

BC4J - How can I get java.sql.Connection ?

Hi,
I am using BC4J for my Application and want to get the java.sql.Connection from ApplicationModule or from anywhere such that I can use the same connection as in ApplicaitonModule, to do some work in the database.
I tried to get it from the SessionInfo :
sessioninfo.getConnectionInfo();
but this returns me oracle.dacf.dataset.connections.Connection
How can I convert this to java.sql.Connection?
Or Is there any other means to get hold of sql.Connection?
Any help would be appreciated.
TIA

Thanks for this reply.. but
I need java.sql.Connection to call a stored procedure in Oracle database and I have to pass oracle.sql.ARRAY to it.
My Stored Procedure looks like:
create or replace PROCEDURE updateRevenueNetworkInfo(revid varchar2, netids Varchar32Array)
where 'Varchar32Array' is my own datatype in the database which is mapped to oracle.sql.ARRAY object in java.
And in order to create oracle.sql.ARRAY I need java.sql.Connection as shown below
oracle.sql.ARRAY pTable = new oracle.sql.ARRAY(desc, connection, netidarray);
I am executing my stored procedure like this:
ArrayDescriptor desc = null; CallableStatement cs = null;
String[] netidarray = {"00-AOL-T1-N003"};
desc = ArrayDescriptor.createDescriptor("VARCHAR32ARRAY", conn);
oracle.sql.ARRAY pTable = new ARRAY(desc, connection, netidarray);
cs = conn.prepareCall( "BEGIN updaterevenuenetworkinfo(?,?); END;" );
((OracleCallableStatement)cs).setString(1,"00-AOL-T1-R3");
((OracleCallableStatement)cs).setArray(2, pTable);
cs.execute();
Is there any way of getting java.sql.Connection such that I can use the same connection as in the ApplicationModule?
OR Is there any other way of passing Array of Strings to a stored procedure in the database?
Thanks for the help.

Access to java.sql.Connection objects

Hi,
The Kodo JDO developers guide states 2 methods to obtain a Connection
object for the database.
The first method makes use of a function getStoreManager(), which
doesn't seem to exist anywhere and which is certainly not mentioned
anywhere in the documentation.
The second method makes use of a class DataSource, which also does not
exist anywhere. I am aware that this class is present in JDK1.4 but we
are using 1.3 and it states Kodo works on this version.
Can anybody please clarify how I obtain a connection using these two
methods?

com.solarmetric.kodo.runtime.PersistenceManagerImpl. The JavaDoc for this
class is not available in Kodo JDO 2.2.x; it is available in Kodo JDO 2.3.0.
The second method makes use of a class DataSource, which also does not

http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/sql/DataSource.html for
more documentation on it.
Note that we do not require that you use a JDBC 2.0 driver (one that
supports javax.sql). We provide our own implementation of DataSource that is
used whenever a connection URL is specified. If you want to use your own
connection pooling etc. with a JDBC 1.0 driver, then you will have to
implement the DataSource interface on your own; we assume that the
ConnectionFactory object implements the DataSource interface.

Need help with a Java-SQL connection

My classmates and I created a DesktopFrame. Within it are reports that require a connection to an MS Access Database. When a report in an InternalFrame is opened: the SQL command works, there is a connection, and everything goes well on the first run.
However, when another InternalFrame is opened or when the same InternalFrame is opened the 2nd time, an error occurs. It produces a java.sql.SQLException: General Error.
Can anyone help me? Thanks in advance.

Provide more info, maybe even some code segments. (Not all). May be easier to help

Java.sql.connection problems

Hi, I hav got this problem:
PRB 1
I have got the JDBC connection established with the OracleDataSource instance on my java application
I wonder if there is a way to check the connection if it is still alive. any hint? i tried connection.isClosed() but that doesn't help.
PRB 2
I am in this scenario:
The connection is established during application start and something goes wrong say like the DB server goes offline in the middle of no where and I do a commit / rollback. I will get a SQLExeption called. But right after the db comes back online.. i tried to do a commit / rollback, the SQLExeption is still persist.
Q1. Does this mean that when the exception is caught, my connection would no longer be valid and I need to restart the application?
Q2. could i reinitialize the connection after the exception to avoid the restart?
Thank you.

Hi, I hav got this problem:
PRB 1

OracleDataSource instance on my java application
I wonder if there is a way to check the connection if
it is still alive. any hint? i tried
connection.isClosed() but that doesn't help.From Java APIs reg. isClosed():This method is guaranteed to return true only when it is called after the method Connection.close has been called.
This method generally cannot be called to determine whether a connection to a database is valid or invalid. A typical client can determine that a connection is invalid by catching any exceptions that might be thrown when an operation is attempted.

You don't need to restart the application, but you might want to check if the connection is null. If it is, you might have to try a new connection. Probably, your application can quit trying for a connection after 'x' number of attempts.

Java.sql.Connection charset property

Hello!
AFAIK, usual way to establish JDBC connection to DB using 1-byte encoding
was:
props.put("user",user);
props.put("password",password);
props.put("charSet",encoding);
Connection con = DriverManager.getConnection(url,props);
How to do the same with JDO PersistenceManagerFactory?
Does Kodo have appropriate optional property?

Note that in the mean time, it is possible to work around this issue by
supplying a DataSource object to our PersistenceManagerFactory.

Serialization of java.sql.Connection

Hi ,
I just came across a input from my colleague that Connection object once created are not serializable across jvm's
Is it true??
fast yes or no will help my curosity ....giving reason also will be genrousity ...anyway I will test this now

It can't be done.
The reason is that a connection uses a network resource (such as a TCP/IP socket) which uses the network stack on the machine, and eventually the machine's hardware. It is not possible to serialize things like a connected socket, because it's significance is machine-specific, not only in terms of a virtual address (such as an IP address), but also in terms of the way the operating system is using the hardware.
Serialization is only good if what you're serializing is only data.

Connection error using import java.sql.*;

I have a very strange error. See the code below:
import java.sql.*;
import java.lang.*;
class a7 {
public static void main(String args[]) {
String kolom,ko = new String();
String db = "devarbn1";
String url = "jdbc:odbc:"+db;

String driver = "sun.jdbc.odbc.JdbcOdbcDriver";
String BasisQuery = "select COLUMN_NAME " +
" from all_tab_columns " +

System.out.println("Database: " + db);
Connection con;
try {

} catch (java.lang.ClassNotFoundException e) {
System.err.print("ClassNotFoundException: ");
System.err.println(e.getMessage());
try {
con = DriverManager.getConnection(url,login,password); //this line gives an error!!!
and so on.....
This is a fragment of the whole program. All of a sudden I cannot compile it anymore using jdk1.3 or jdk 1.4 (I never had compiling problems before with this program)
It gives the following error message: incompatible types, found Connection.
I haven't got a clue what went wrong. I have a lot of other java files in which a connection is involved. I cannot compile any of them anymore. Even reinstalling jdk1.4 or 1.3 doesn't help. Can anyone please help me?
Thanx, debeumers

You obviously don't understand how CLASSPATH works:
http://java.sun.com/j2se/1.4.2/docs/tooldocs/windows/classpath.html
I think you have to add the current directory to the CLASSPATH in order to run your Test:
java -classpath . TestNote the "dot" after -classpath. That tells the class loader to start looking in the current directory. since your Test.java doesn't have a package statement, I'm assuming that Test.class is in the same directory as Test.java.

Java Applets connecting to Oracle DB thru OAS (JNDI)

i am developing an application, like i said before, i am using three applets, one controls a webcam, (records an image to disk and oracle), another controls a Electronic signature pad (records an image to disk and oracle), and finally a finger print reader (the same with this), at the beginning i didnt have any problem at all connecting this applet to the database, but top management wants to do things in another way, not allowing me to connect the applet directly to the database for security reason, My app resides on Oracle Application Server, and i use DataSource and Connection Pooling,
I want that this applets use the available datasource on OAS to connect to the Database, due that the DataBase IP Address wont be public but OAS IP address will, I know that i must use JNDI to accomplish this, but i didnt have any results at all
