hi all

when i try to retrive the data from a DB using JDBC:ODBC i have a premission Error
can any one help me with it

When you start Remote object, you need to provide codebase and policy like below:
java -Djava.rmiserver.codebase=http://myhost/..../ -Djava.security.policy=policy RemoteObject
your policy file is like
grant
// Allow everything for now
permission java.security.AllPermission;
// allows anyone to listen on un-privileged ports
permission java.net.SocketPermission "*:1024-65535", "listen,accept,connect";
please refer to www.java.sun.com/j2se/1.4.2/docs/guide/rmi/codebase.html
Hope help you.

RMI with JDBC

Hello,
this is the first time that I work with RMI.
In fact it isn't so hard.
But I've made an interface that do the operations on my database.
Do I also have to program a locking mechanism?
Does anybody made such a system, or what do you recommand.
I want to make a simpel program that uses a database on another pc.
tnx

Hi Twims
Im asking if you could make me a favor... As I can see you know RMI with JDBC... And at this moment I need a client and server programs to connect to a database, execute SQL commands and retrieve information to client.
If you could send me those programs please do it to [email protected] or [email protected]
Thanks in advance

ORA-03115 Error using CLOB with JDBC

When I try to access CLOB field data with JDBC driver, I gets following error:
ORA-03115: unsupported network datatype or representation.
I am using JDBC 8.1.6(Thin), Oracle 8.0.5
on Linux OS.
what's the problem ?
Thank you for any help.
Taesoo.

if it is a bug, then its better to upgrade the database to 10.2.0.4. it is the stable verion in 10g.

Using OS_ROLES with JDBC Driver

I can't get my JDBC connections to pick-up the OS ROLES I have configured. Does the OCI driver support OS Roles?
I'm using 10gR2 with latest JDBC drivers, running on Windows XP.
If I connect locally with sqlplus then the roles are established correctly. However, establishing the 'equivalent' connection from Java yields a user with no ROLEs defined, i.e. they are not being picked-up from the OS.
Is there a trick or is it not supported?
I believe I have the database and the OS groups setup correctly and, as I say, it works fine with a sqlplus connection.
If anyone either knows how to do, or knows that its not supported then please let me know.
Thanks,
Richard.

to my knowledge this is not supported in jdbc specification2.0 and 3.0 and jdbc drivers are complied to this standards.
connecting with sql client is entirely different with the connection using java thin drivers.
thanks,

Running/ Using RMI with JDevelope 9.0.4

I am trying to learn to use RMI (Remote Method Invocation), have used the example found in Deitel and Deitel, only I've come to run them and the examples on running the application suggests one method.
I'm wondering if JDeveloper has a quick, easy way to run or use RMI within applications

OC4J provides the proprietary Remote Method Invocation (RMI)/Oracle RMI (ORMI) protocol.

How to use setCLOB with JDBC.

Hi,
from oracle jdbc document, i know how to use getClob method. but i wonder how to insert a new record included a clob field (setClob). but clob is an interface.
it seem that it can not be successful to use setclob directly.
my friend has a way : insert an empty clob into database, then seek this record, and update it with full info again.
please help me!
thank in advance.
wu jianhua.

A few ways:
1. Use the LOBs got from a ResultSet, for example,
Clob x = rs.getClob(1); //you get an oracle.sql.CLOB object
pstmt.setClob(1, x);
2. use oracle.sql.CLOB
public static CLOB empty_lob() throws SQLException;
creates an empty lob.
public static BLOB createTemporary(Connection conn, boolean isCached, int
duration);
creates temp lob.
Those methods create object of type oracle.sql.CLOB.
refer to Oracle jdbc doc for this.

How can i Use SERVLET with RMI to avoid trust certificate

I know that for begining RMI, you must launch the server and the client.
for the server i use :
java -Djavax.net.ssl.trustStore=server.keystore -Djavax.net.ssl.keyStore=server.keystore -Djavax.net.ssl.keyStorePassword=server TestServer
for the client I use :
java -Djavax.net.ssl.trustStore=client.keystore -Djavax.net.ssl.keyStore=client.keystore -Djavax.net.ssl.keyStorePassword=client TestClient
and all work fine.
but i want to use a servlet for rmi client and i wrote this:
public class AppelServlet extends HttpServlet
     public void doPost(HttpServletRequest request, HttpServletResponse response)
     throws ServletException, IOException
          try
               System.out.println("Registering secure RMI socket factory ...");
               java.rmi.server.RMISocketFactory.setSocketFactory(new SecureRMISocketFactory());
          TestRemote test = (TestRemote) Naming.lookup("rmi://127.0.0.1:7123/TestClient");
String reponse=test.toLowerCase("HELLO WORLD");
               System.out.println("la reponse est : "+reponse);
     catch (Exception e)
          System.out.println("test client exception: " +e);
PrintWriter out = response.getWriter();
          response.setContentType("text/html");
and i have the following error on tomcat:
Registering secure RMI socket factory ...
test client exception: java.rmi.ConnectIOException: error during JRMP connection
establishment; nested exception is:
javax.net.ssl.SSLHandshakeException: Couldn't find trusted certificate
i think i must precise how to indicate the truststore like in the first case.
help me please.
hamdi

Hi,
Try doing the following steps.
Assuming you have a certificate obtained
Export the certificate into a .cer file.
On IE, goto tools->internet options->content->certificates, and export to a .cer file.
Using keytool of java import the certificate to the store that can be used doing the following command.
keytool -import -alias <ailas> -file < .cer filename> -keystore <storename here>
set the javax.net.ssl.trustStore and javax.net.ssl.trustStorePassword properties at the command prompt using the command below.
java -Djavax.net.ssl.trustStore=<storename> -Djavax.net.ssl.trustStorePassword=<password> <classname>
Let me know if this helped.
Also take a look at this link for using RMI with SSL

Using JCheckBox/JComboBox with JDBC

hello.
i was just wondering does any of you have links to web pages that include tutorials (and source code) on using JCheckBox with JDBC. would any of you who have experience with using JCheckBox and JDBC together be able to give me a few tips on how to select certain data from a table using JCheckBox and JButton? (examples of such data could be CD/DVD/Game data - i want users of my video library system to be able to view CD/DVD/Game information by name, age category, type and year)
thank you very much for your help.

hello.
Thanks for the replies. I�m wondering do any of you
have links to web pages that include tutorials and
source code on using JCheckBox, JButton and JTextArea
with JDBC. Wow, another person who's never heard of Google. Amazing!
would any of you who have experience with
using JCheckBox, JButton, JTextArea and JDBC together
be able to give me a few tips on how to select
certain data from a table using JCheckBox + JButton
and display the data in a JTextArea? examples of such
data could be CD/DVD/Game data - i want users of my
video library system to be able to view CD/DVD/Game
information by name, age category, type and year.
Users should be able to click on a check box (e.g.
view by name, age category, type or year) and press a
button. What would happen then is that data would
appear in the text area (which could be placed
beneath the check box + button inside a frame).
thanks for the help.Find the tutorials, go through them, then come back here when you have a specific problem you need help with. Yes we have experience in these areas, but we're not going to post links and code here just because you're too lazy to use Google and find it yourself.

Help needed with JDBC - please help! (newbie)

hi all
i m new to jdbc
i have installed MySQL server on my winxp machine
i used the command:
mysql -p -u root
Enter password: ****now when writing a prog i m getting a prob at this piece of code:
Connection con=DriverManager.getConnection("jdbc:odbc:books","root","root");wot is wrong wid this code?
please help......
thanks in advance

There are about 20 different things that could be wrong a this point; I'm not going to list them all. If you want specific help, you need to post specific information. This is usually done by posting either a stack trace from an exception, or a more complete section of code and a description of the problem and ALL the symptoms. You have all the information on what you've done, we have none of it.
Instead of trying to diagnose whats wrong with your ODBC setup, I'm going to give you some strong advice; don't use ODBC with JDBC if you can avoid it, and with MySQL you can avoid it. It makes things simpler, less can go wrong, and you don't have to configure a DSN on every machine that you install the program on.
To use "pure" JDBC without ODBC for MySQl:
1) download the JDBC driver (you might already have this)
http://dev.mysql.com/downloads/connector/j/3.1.html
2) follow the installation instructions
http://dev.mysql.com/doc/refman/5.0/en/java-connector.html
In particular, make sure your classpath is set correctly
3) Here's an example of loading the driver and establishing a connection
http://dev.mysql.com/doc/refman/5.0/en/cj-connect-with-drivermanager.html
Note the form of the connection URL,
"jdbc:mysql://localhost/test?user=monty&password=greatsqldb"
This is what an URL without ODBC looks like; there is no DSN, which means no DSN has to be configured.
4) The MySQL database has some built-in security, to prevent malicious connections from outside computers. Solutions to that and other common problems are here:
http://dev.mysql.com/doc/refman/5.0/en/cj-faq.html

Can anyone help me on this issue?
Regards,
Bindu

I have already tried this before and this not work too, but strange that even if I use JDBC:ODBC bridge driver, the return value for output parameters are not correct, that is, only return the value that I input but not the value after executed in the procedure....
The code that I used with JDBC:ODBC bridge is as follow:
public static void main(String[] args) {
String url = "jdbc:odbc:;DRIVER=SQL Server;Persist Security Info=False;database=db;Server=sql;uid=sa;pwd=pwd";
          Connection con;
          ResultSet rs = null;
CallableStatement callS = null;
          try {
               Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
          } catch(java.lang.ClassNotFoundException e) {
               System.err.print("ClassNotFoundException: ");
               System.err.println(e.getMessage());
          try {
               con=DriverManager.getConnection(url);
callS = con.prepareCall("{ call dbo.CpJavaTest (?)}");
callS.registerOutParameter(1, Types.INTEGER);
callS.execute();
rs=callS.getResultSet();
int ret = callS.getInt(1);
System.out.println("return value : " + ret);
               while (rs.next()) {
                    String f1 = rs.getString(4);
                    String f2 = rs.getString(5);
                    System.out.println(f1 + " " + f2);
          } catch(SQLException ex) {
               System.out.println("SQLException: " + ex.getMessage());
The value of the output parameter is same as what I inputed! Hope any one can teach me how to correct it...
Thank you very much!
