Import java.sql.*

I am trying to create and application that connects to a database (MySQL) to do some queries. I put this
import java.sql.*;
at the top of my file and got this error message "package java.sql does not exist".
Can anyone shed some light on this for me? :)

My other guess is a typo, perhaps with an invisible/hard-to-see character. Delete the line and type it in, again.

Cannot import java.sql.BaseQuery

Hi,
I am trying to run the following example using JDK6:
import java.sql.BaseQuery;
import java.sql.DataSet;
import java.sql.Select;
public interface UserQueries extends BaseQuery {
    // Select all users
    @Select (sql ="SELECT userId, firstName, lastName FROM Users",
             readOnly=false, connected=false, tableName="Users")
    DataSet<User> getAllUsers ();
    // Select user by name */
    @Select (sql ="SELECT userId, firstName, lastName FROM Users"
             + "WHERE userName=?", readOnly=false, connected=false,
             tableName ="Users")
    DataSet<User> getUserByName(String userName);
}But I get the error in the import statement itlself. It is not able to import these classe-
import java.sql.BaseQuery;
import java.sql.DataSet;
import java.sql.Select;
Are they shipped with JDK 6?
thnx
Sanjeev.

Because those classes don't exist. A simple, and very quick, perusal of the API docs would have told you this.

Connection error using import java.sql.*;

String db = "devarbn1";

System.err.println(e.getMessage());
try {

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?

Hi friends...
I've read the last post...
The problem that I have is as follow....
1. I have installed on my machine MySQL 5.0 Server running
1.1 I have a database called "base1"
1.2 User "root", password "works"
1.3 I have the following sentence to connect it using JDBC
Connection con = DriverManager.getConnection("jdbc:mysql://localhost/base1", "root", "works");
More notes:
- I use the JDBC 5.0
- My Machine is a Windows XP SP2 Pentium 3.0 512Mb
and it connects��
but I have this environment to develop applications, now that I want to connect to Production Environment happens the following:
2 The Production database is mounted on a Linux Server with MySQL 3.2.
2.1 I change the sentences as follow:
Connection con = DriverManager.getConnection("jdbc:mysql://192.168.0.7/base1", "user", "password");
2.3 But a message appears when I run the Java Program:
java.sql.SQLException:Access denied for user: '[email protected]' (Using password: YES)
2.4 As you can see it changes the IP Address...
More notes:- I have the MySQL Query Browser and I got connection.
- The IP that display the Error Message is my Second IP configurated on my Network Properties.
- Server is a Pentium 4 3.0 GHz 2Gb Linux Red Hat 3.0
I leave this case for the spider... I hope that somebady has the solution.
What is the problem? Why the JDBC doesn't respect the IP that I wrote.

That usually means something is wrong with the syntax of your sql.
As a guess 'text' is probably a keyword and shouldn't be used as a field name. It is possible that the same is true for 'id'

Create a different statement to run the update statement in your loop.
Using the same statement as your result set was generated from will create this error.
Statement stmt = conn.createStatement();
Statement stmt2 = conn.createStatement();
ResultSet RS = stmt.executeQuery(" SELECT * FROM IncompleteTasks");
while(RS.next(){
stmt2.executeUpdate(update_table);

Java.sql.SQLException: Io exception: End of TNS data channel

Hello folks,
Has amyone encountered this exception? If so, could you please shed some light for what might be going wrong?
Here is my confuguration:
400MB RAM
1.2GHTz processor
Win2K Pro
Oracle server 9.0.1
JDBC Thin driver (libs for 9.0.1)
Scenario:
My Java code uses Oracle Spatial to insert SDO_GEOMETRY objects into my DB model.
I have a config file where I store my connection properties, e.g.,
<DBConnection name="twatest">
<JDBCDriver>oracle.jdbc.driver.OracleDriver</JDBCDriver>
<URL>jdbc:oracle:thin:@saturn:1521:saturn</URL>
<Username>user1</Username>
<Password>twatest</Password>
</DBConnection>
We have 2 schemas defined: user1 and twatest.
The problem first occured when I switched from user1 to twatest. Consequent attempt to run the process as user user1 failed! The Java SQL statements do not use schemas (so they default, I suppose, to the default schema for that particular user, in our case being user1-->user1, twatest-->twatest).
The problem happens in the following Java class (search for "HERE" to see where exactly the problem occurs):

Suresh -- I'd probably log a TAR with Oracle support for this question if you definitely need it resolved. Support have access to all manner of existing cases, so this may be something they have seen before.

How do I create a Dynamic java.sql.Date ArrayList or Collection?

I Have a MySQL table with a Datetime field with many values inserted.
I want to know which is the Best way to capture all the Inserted DB values inside a Dynamic Array.
I get errors that state that I should use Matching data-types, and plus I don't know how to create or fill a Dynamic Date ArrayList/Collection.
Please Help, I need this urgently...

Actually I have No idea as How to get a Result set into an ArrayList or Collection. Please tell me how to do this Dynamically. I have like 25 records in that Database table, but they will grow, so I would really appreciate to know the code to do this. I suspect my problem is in the bolded part of my code.
Thank you very much Sir.

SID_NAME =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = IP_NUMBER)(PORT = 1521))
    (CONNECT_DATA =
      (SERVICE_NAME = SID_NAME)
)I am trying to run the following sample code:
* This sample shows how to list all the names from the EMP table
* It uses the JDBC THIN driver. See the same program in the
* oci8 samples directory to see how to use the other drivers.
package basic;
// You need to import the java.sql package to use JDBC
import java.sql.*;
class Employee
public static void main (String args [])
       throws SQLException
    // Load the Oracle JDBC driver
    DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
    // Connect to the database
    // You must put a database name after the @ sign in the connection URL.
    // You can use either the fully specified SQL*net syntax or a short cut
    // syntax as <host>:<port>:<sid>. The example uses the short cut syntax.
    String url = "jdbc:oracle:thin:@IP_NAME:1521:SID_NAME";
    String userName = "USERNAME";
    String password = "PASSWORD";
    if (args.length > 0) url = args[0];
    if (args.length > 1) userName = args[1];
    if (args.length > 2) password = args[2];
    //Connection conn =
    // DriverManager.getConnection (url, userName, password);
Connection conn =
    DriverManager.getConnection("jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=IP_NUMBER:1521)(PORT=1521)))(CONNECT_DATA=(SID=SID_NAME)(SERVER=DEDICATED)))", "USERNAME", "PASSWORD");
    // Create a Statement
    Statement stmt = conn.createStatement ();
    // Select the ENAME column from the EMP table
    ResultSet rset = stmt.executeQuery ("select object_name from user_objects");
    // Iterate through the result and print the employee names
    while (rset.next ())
      System.out.println (rset.getString (1));
}I also used the following IP
Connection conn =
      DriverManager.getConnection (url, userName, password);

Replace the url with
String url = "jdbc:oracle:thin:@IP_NUMBER:1521:SID_NAME";

Importing java class in servlet

hi,
i need to import a java class file in a servlet. how do i do that.
also, when i remove the following lines, the import & the line following line,
//JavaClass class=new JavaClass();
msgsend class=new msgsend();
it compiles ok, else i get the error,
out.println cannot resolve symbol.
the code of the servlet is as follows:
import javax.servlet.*;
import javax.servlet.http.*;
import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpServlet;

to=request.getParameter("to");
from=request.getParameter("from");
bcc=request.getParameter("bcc");
cc=request.getParameter("cc");
subject=request.getParameter("subject");
System.out.println(to);
//JavaClass class=new JavaClass();
msgsend class=new msgsend();
System.out.println(2);
out.println("<body align= center bgcolor='white'>");
out.println("<br><br><br><br><H2 align=center> ");
out.println("<FONT color=#ffffff face=arial size=2></FONT>");
out.println("</FORM>");

out.println("<footer align=center><font size=1><a href='/wpc.html'>");
out.println("Home Page");
out.println("</a></footer>");
//place javascript function for exiting window
out.println("</form>");
out.println("</body>");
out.println("</html>");
} catch(Exception e){ }
out.close();}
pls help,
thanx,

You have to do like the others import. You have to put import and the complete path(with all the packages).
For example:
import mypackage.msgsend;
and if you wouls like to import all the classes of a package use:
import mypackage.*;

ADF Bc third party JDBC Driver java.sql.SQLException: No suitable driver

Hello all
I am using JT400.jar file to connect to AS/400 data base in my JSF/ADF Application.
We are using shared library for all non oracle jar files . and my application fails with error message
## Detail 0 ##
java.sql.SQLException: No suitable driver
During runtime. even though i am importing the required jar files from shared library settings in server.xml / application.xml
When i don't have the entry in shared library for this jar file it will fail during deployment time it self, but with shared library link it works during deployment but fails during runtime
it will work during runtime if i add my jar file to BC4J/lib folder. but team responsible for mintaining application server don't accept adding non oracle jar files to oracle installation folders
i have also posted this in jdev forum
Please Advise
Thanks

Thanks for reply

               conn = DriverManager.getConnection(url+dbName,userName,password);
               System.out.println("Connected to the database");
               conn.close();
               System.out.println("Disconnected from database");
          } catch (Exception e) {
