i want access to database in page html with use AppletFirst of all, that doesn't make any sence, if it's a single user application make it a java
application.
If it's a multu user application make it a client server where the web server connects to
the database when the client requests a connection.
When the applet connects to the database any client running the applet needs a
connection to your database server, the client needs the jdbc drivers and the client's
jre needs to find them (set classpath with runtime parameters or set the classes in
javadir lib). After that the client needs to change thiere java.policy or you need to sign
the applet.
Needless to say that's a lot of trouble. And if you go through all that trouble the client
can de-compile your applet and see the connection to the database server and the
server name. Now the client can destroy your database or worse see date it is not
supposed to see.
Since you are a brainless ... who needed to post this question 6 times did not respond to any of my post in your other threads I can just say good luck with your problem.

Problem in connecting Database by using SQL Developer

Hi,
I recently installed SQL Developer after installing Oracle 10g and am trying to connect existing database. could anybody help me to connect and what credential should i required to connect.
Thanks in advance
LN Reddy

I am new to oracle myself, so I apologize if this information is not helpful. But I have a number of connections to a local database on my laptop. The way that I connected is using the 'Basic' tab with the following settings:
Hostname: localhost
Port: 1521
SID: orcl
And of course the username above.
I hope that might be helpful.

Beginner on JDBC. problem to connect database postgreSQL

hi there everyone,
new to JDBC.
not sure, what's wrong with that.
I am using XP, postgreSQL 7.3.3 - the database is fine ( i can create a table via cygwin).
- i have downloaded the pgSQL jdbc driver also set the classpath.
thanks in advanc
===================================
import java.sql.*;
public class Example {
public static void main(String args[])
          String userName="user1";
     String password="whatever";
try
String url = "jdbc:postgresql:myDB";
               Class.forName("org.postgresql.Driver");
Connection myConnection= DriverManager.getConnection(url,userName,password);
} catch ( java.lang.Exception ex){ ex.printStackTrace();}
===========================================================
Connection refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.

Thanks colbell
=========================
I have got them or newer verion.
crypt 1.0-1
cygipc 1.13-2
cygwin 1.3.16-1
gcc 3.2-3
libncurses6 5.2-8
libreadline5 4.2a-1
readline 4.2a-1
zlib 1.1.3-6
Sun JDK 1.3
Ant 1.5
===================
i should have this perl 5.8.0-1 but when i install it directly from the net, it only has perl 5.6.2.-1 and it's doc 5.8.0-1.
i think i have installed the ant correctly but is there any way that i could test it??
what is the different between
String url = "jdbc:postgresql:myDB"; and
jdbc:postgresql:localhost:5432/myDB
Just check the port number that you're actually
using.
how and where can i find it out??? or u mean the usually postgreSQL's port number??
Also make sure that you have installed cygipc and that
it is running. Take a look through
<cygwin>\usr\doc\Cygwin\postgresql-7.3.2.READMEi have installed cygipc - any ways i could test it?
thanks in advance

Thanks and Regards,

For installing JSTL, all you need are the jar files in the web-inf/lib directory.
- No entries in web.xml
- no tld files lying around
- no problems!
I think you may have a versioning problem here.
What version of Tomcat are you using?
With JSP1.2 (eg Tomcat 4), you should be using JSTL1.0. <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
With JSP2.0 (eg Tomcat 5), you should use JSTL1.1. <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
Note the difference in the URIs. - the second one includes a /jsp
Currently you are using the URI for JSTL1.0, but you look to have the tld from JSTL1.1. If you are using a JSP1.2 container, I don't think it could read this tld file, hence the error.
Try installing the correct version of JSTL, properly (ie as they tell you in the readme file) and it should all work.

Problem in connectivity with database

Hi anyone,
I have installed Oracle-8i database and Developer-6i in Windows-95. I am facing the following problem in connectivity:
In the connection dialogue box, I enter user/passwd as scott/tiger and host string as odbc:polite. I am getting an error message "OCA-30002 ubofscr function not supported".
In schema builder, table1 is the default name of a new table created. On renaming the table name, I am getting the error message:
"OBE-15467: Name already in use. Please choose another name"
whereas no such table name exists in the database.
If table1 is accepted as the new table name, I am encountering another error message:
"OBE-15361: Error in creating primary/unique constraint for table1. [POL-5228] message file is not loaded".

Please use CODE tags when posting code. You are losing some of the plus signs of string concatenation to the forum's formatting beast.
Preferred solution: Don't use Access as a database. The JDBC-ODBC bridge is always troublesome.
If you must use Access...
Well the message is easy enough to understand: it can't find the database db1.mdb.
You say you put db1.mdb in the web directory. Obviously the computer is not looking there (silly computer for not looking where you put the file)
So it is up to you to be smart and tell the computer exactly where to go.
Using application.getRealPath("/db1.mdb") in place of "db1.mdb" will probably work in a JSP.
String databaseURL = accessDBURLPrefix + application.getRealPath("/db1.mdb") + accessDBURLSuffix;cheers,

Problem in connecting to Access Database.

Hi,
     I am new to this Java/JSP Concepts. I am using IBM Websphere Studio(Application Developer 5.1.2). I am facing a problem to connect to the Access database. I have written a java file to connect to the Access Database. When i compile my java code and run it. It was working fine and i am able to insert into the Access database.The java file is working fine without errors. But when i create an object in the jsp and called the methods through that object i am getting "java.lang.ClassNotFoundException: sun.jdbc.odbc.JdbcOdbcDriver", "java.sql.SQLException: No suitable driver", "java.lang.NullPointerExceptionexceptions" exceptions.
Please help me in solving the problem.

Check if the OdbcDriver is in the classpath

Problem in connecting JSP with Oracle 9i.

Hi,
I am having problem in connecting JSP with Oracle 9i.
I am using windows XP and my JDK version is 1.4. For executing JSP I am using
"jakarta-tomcat-5.5.4-preconfigured". My database name is global.
I have set java_home, j2ee_home, oracle_home, path, classpath as follows:
j2ee_home=c:\sun\appserver
java_home=c:\sun\appserver\jdk
oracle_home=C:\oracle\ora92
path=C:\Sun\AppServer\bin;C:\Sun\AppServer\jdk\bin;C:\oracle\ora92\bin
classpath=C:\Sun\AppServer\lib\j2ee.jar;C:\oracle\ora92\jdbc\lib\ojdbc14.jar;C:\oracle\ora92\jdbc\lib\nls_charse
t12.zip
My code is as follows:
<%@ page language="java" %>
<%@ page import ="java.sql.*"%>
<%
try
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
Connection conn = DriverManager.getConnection ("jdbc:oracle:oci8:@global", "scott", "tiger");
catch(SQLException e)
out.println(""+e);
out.println("Connected");
%>
I tried other program:
<%@ page language="java" %>
<%@ page import ="java.sql.*"%>
<%
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:global","scott","tiger");
out.println("Connected");
%>
I am getting following error:
exception
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 5 in the jsp file: /jsp/oracle.jsp

In ealier versions og MDM i did not give any username or password whwn I made a new repositirt. Do you need to that no?
I see in the mds.ini file that there is defined a user "Sql Server DBA Username=master ". I sthis the user we shall use or is there another user?

Problem in connecting to database from webdynpro for java

Hi
I have a problem in connecting to database from webdynpro application
I am using oracle 10 express edition as database and was able to connect to database from a java application.But was unable to connect from a webdynpro for java.
<b>I guess webdynpro for java uses open sql instead of vendor sql(I looked in the visual admin ,DB is using open sql) so unable to connect to database.Am i right.?</b>
Do i need to make any settings in the visual admin to make it work?
How to solve this problem.Please give me pointers
Thanks
Bala

Hi,
For connecting to Oracle, either you can use the normal JDBC connectivty code directly which is given below :
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@Oracle_server_ip:Oracle port:SID of the Database","user_name","password");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("your query");
In case you want to fetch data through ejbs, these are the steps to be followed :
1) Open the J2EE perspective
2) Create an EJB Module project
3) Right click on ejbModule, create a new EJB (select your EJB type)
4) While creating the ejb itself, you can add business methods by clicking Next in the UI. Another option is after creating the ejb, write the method in the bean, then select the method from ejb-jar.xml -> <bean name> ->method. Right click and select propogate to local & remote.
5) Double click on ejb-j2ee-engine.xml. select your bean and specify a Jndi name for eg: MyJndi.
6) Right click on the EJB project and add classes12.zip file (provided by Oracle) to its build path. (under libraries tab). Also check the same file under Order & Export.
7) Create an Enterprise Application project.
8) Right click on the EJB module project and select add to EAR project, then select the created EAR project.
9) Right click on the EJB project, select Build EJB Archive
10) Right click on the EAR project, select Build Application Archive
11) Open the WebDynpro perspective, open a new project, right click on the project ->properties. Do the following configurations :-
Java Build path - select the EJB project from projects , check the selected project under Order & Export
Project references select the EAR project
WebDynpro references select sharing references tab, click add & make an entry as : <vendor>/<EAR project name without .ear extension>
You can find the vendor name under application-j2ee-engine.xml file of the EAR project. By default it is sap.com. So if my EAR projects name is ABC, my entry would look like sap.com/ABC
12) Now the configurations are over and the EJB can be invoked by writing the client code inside the webdynpro component. Like:
InitialContext context = new InitialContext();
Object obj = context.lookup("MyJndi");
MyEJBHome home = MyEJBHome)PortableRemoteObject.narrow(obj,MyEJBHome.class);
MyEJB mybean = home.create();
int a = 0;
a= mybean.add(10,15);
wdContext.currentContextElement().setSum(a);
where MyEJB is my EJB name and MyJndi is my JNDI name
To connect to Oracle , you can write the usual Java code (given below) as a business methos of the ejb (similar to add() method in the example). And access it like mybean.<businessMethodName>().
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@Oracle_server_ip:Oracle port:SID of the Database","user_name","password");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("your query");

Problem in connecting to database using oracle jdbc thin driver

hi
i am trying to connect to a database using oracle thin driver.
i am getting following error:
java.sql.sqlexception:Io exception: the network adapter could not establish the connection
Io exception: the network adapter could not establish the connection
the connection string has the property of using a dedicated server
for this reason i have put USE_DEDICATED_SERVER=ON in sqlnet.ora file...
we did not face this problem while connecting to other databases which do not have the property of dedicated server in their connection string in tnsnames.ora file.
please suggest a solution for this.
thanks and regards,
asif

If you are using the thin driver, sqlnet.ora does not come into play. None of Oracle networking does. That is one of the great things about using the thin driver, no need to have the client installed.
That error is due to incorrect connection info you are supplying or the machine you are connection from can't ping the machine it is trying to connect to.

We cannot help if you don't give us the error number that you get.
Also something that you might want to do is to search this error number on OTN.
