Oracle Extensions Examples & WebLogic Server

I've run the oracle extensions examples with weblogic server and cannot get the
string representation for the addresses, as indicated in the examples documentation.
I get a hexadecimal representation. I'm running structs, refs and arrays business
object examples. My output is, for example:
[java] Employee#: 103
[java] Name: Fred Couples
[java] Address: 0x39323031205061726B205374
[java] 0x416C6578616E64726961, 0x5641
[java]
[java] Employee#: 105
[java] Name: David Toms
[java] Address: 0x343433312043616E616C20537472656574
[java] 0x4E6577204F726C65616E73, 0x4C41
[java]
So my questions is how do I get a string representation? Is there a hextostring
conversion java method? Why do I get hex in the first place?. The source file
is using system.out.println.
The output should be, for example:
Address: 4431 Canal Street
New Orleans, LA
Look at the AddressBO.java file in the C:\bea\weblogic700\samples\server\src\examples\jdbc\oracle\extensions
directory.
I use BEA 7.0 and Oracle 9.0.1.1.1.
Steve.

The datatype for address may clob.Clob values cannot be retrieved directly .please try the following code.
Clob clob = rs.getClob(3);
Reader reader = clob.getCharacterStream();
int l=1;
StringBuffer str = new StringBuffer();
if(reader!=null)
while((l=reader.read()) != -1)
str.append(new Character((char)l).toString());
reader.close();

JDBC - Oracle Installation

I am running a servlet on Lunux/Apache/Tomcat and I need to make a JDBC connection to Oracle on another computer. I have moved the Oracle 'classes12.zip' to the ...j2sdk1.4.1/bin directory and I have also added it to the CLASSPATH environment variable.
When I try to execute
DriverManager.registerDriver(new Oracle.jdbc.driver.OracleDriver());
I get the following error
'java.lang.NoClassDefFoundError oracle/jdbc/driver/OracleDriver'
Any advice please?
Thanks for the help
Glen

Hi everyone,
I have a similar "Class not found exception" when using classes12.zip in the WEB-INF/lib folder (under win2000)
A servlet tries to make a connection and bombs out.
I am using "oracle.jdbc.driver.OracleDriver" with the zip file in the above folder..? Mysql and MSSQL both work but this one doesn't ...
Is there an issue with the .zip extension?? does in HAVE to be .jar??
My URL is jdbc:oracle:thin:@<name>:<port>:<sid> but that's another issue... DO I have to provide a username and password and if so could someone post up this URL please..
Thanks
Dave

How to specify JDBC Oracle url using deployment tool - Entity Bean

Hello I'am new to EJB.
When creating a entity bean-managed persistence and you need to specify the jdbc url with user name
and password to establish a connection object, how does one specify that in the deployment
tool?
Heres an example of what has in the J2EE tutorial has in AccountEJB to get an connection object
private String dbName = "java:comp/env/jdbc/AccountDB";
private void makeConnection() throws NamingException, SQLException {
InitialContext ic = new InitialContext();
DataSource ds = (DataSource) ic.lookup(dbName);
con = ds.getConnection();
Now if my oracle jdbc url is to be jdbc:oracle:thin:@Abe:1521:dev
ie My host is Abe, port number 1521 and database name of dev and username/password will be system/manager.
what would my dbName be at the top?
Would my JNDI lookup of a DataSource resource "java:comp/env/jdbc/AccountDB" become "java:comp/env/jdbc/dev" for starters?
In the Resource Factories Reference Code I've add a reference of
Coded Name: jdbc/dev
Type: javax.sql.DataSource
Authentication: Container
and down the bottom of the I've put JNDI Name: MyAccount
according to the AccountClient code of:
Context initial = new InitialContext();
Object objref = initial.lookup("MyAccount");
and put User Name of "system" and Password of "manager"
I'am sure in the source code I have to put
Class.forName("oracle.jdbc.driver.OracleDriver")
else you would get that no sutitable driver error, maybe you don't have to if ejb server is smart enough?
What I'am confuse about is where to specify the jdbc url of "jdbc:oracle:thin:@Abe:1521:dev" ??
Know it won't work because of this vital part. Do you have to put that somewhere else in the deployment tool or properties file, or some other tool??
Please help
Thanks

One thing I don't like about EJB is that everything is transparent which is good! But its much
harder to debug! :( Tried to see if I can figure it out. Hope someone has seen this problem before?

Error when using jdbc:oracle:kprb:

Hi folks!
I'm having a hard time trying to solve this one, here's the situation:
I've developed a java stored procedure and ulpoaded to the database using loadjava, which gave me no problems.
Then i've set permissions for the procedure:
BEGIN
dbms_java.grant_permission(
          grantee => 'XMLADMIN',
          permission_type => 'SYS:java.io.FilePermission',
          permission_name => '/home/xmlgate/inbound/*',
          permission_action => 'read');
dbms_java.grant_permission(
          grantee => 'XMLADMIN',
          permission_type => 'SYS:java.io.FilePermission',
          permission_name => '/home/xmlgate/outbound',
          permission_action => 'write');
dbms_java.grant_permission(
          grantee => 'XMLADMIN',

          permission_action => '');
COMMIT;
END;
But when i run the code inside the databse it always gives java.lang.NullPointerException.
Here's the main class:
package packupload;
import java.sql.*;

public class connection {

public static Connection getConnection() throws SQLException {

String default8iConn = "jdbc:oracle:kprb:";
Connection cn = null;
try {
// Register the JDBC Driver
Driver d = new oracle.jdbc.driver.OracleDriver();
//Connect with Native (kprb) Driver if inside Oracle8i
if (insideOracle8i())
cn = DriverManager.getConnection(default8iConn);
else
cn = DriverManager.getConnection(thinConn,username,password);
cn.setAutoCommit(false);
return cn;
} catch (Exception e) { throw new SQLException("Error Loading JDBC Driver" + insideOracle8i());
public static boolean insideOracle8i() {
// If oracle.server.version is non-null, we're running in the database
String ver = System.getProperty("oracle.server.version");
return (ver != null && !ver.equals(""));
Any help would be greatly aprecciated.

Hi..
I did it but here i am wondering becoz my RFC connection SAPSLDAPI works fine
But at transaction SLDCHECK..it throws an error like
Calling function LCR_LIST_BUSINESS_SYSTEMS
Retrieving data from the SLD server...
Function call returned exception code     4
=> Check whether the SLD is running!
Summary: Connection to SLD does not work
=> Check SLD function and configurations
But the SLD URL pops up and opens wih put any error.in a same fashion,it happens in SXMB_ADM--> integration engine config.it says connections to SLD doesnot work
any idea to verify
Thanks

Installing JDBC, Oracle, PI 7

I am configuring a JDBC adapter (sender) in SAP PI 7, against a Oracle 10g database. My configuration is like this:
JDBC Driver: oracle.jdbc.driver.OracleDriver
Connection: jdbc:oracle:thin:@144.84.236.22:1531:ha1u
When starting the interface I get this error in the communication channel monitoring:
Error during database connection to the database URL 'jdbc:oracle:thin:@144.84.236.22:1531:ha1u' using the JDBC driver 'oracle.jdbc.driver.OracleDriver': 'com.sap.aii.adapter.jdbc.sql.DriverManagerException: Cannot estrablish connection to URL 'jdbc:oracle:thin:@144.84.236.22:1531:ha1u': ClassNotFoundException: oracle.jdbc.driver.OracleDriver'
Based on this I thought that the oracle drivers were not loaded. So I sent an email to the SAP PI admin. They did not know about this issue, and said that when they were attempting to install the driver they got the message "No upgrade needed". I have given them the "How to Install and Configure External Drivers for JDBC & JMS" document, but they have still no luck in correcting this issue.
This is real critical for me, so any input would greatly help. Is there anything wrong with my configuration? Is there anything I can tell my admins, that might help them fix the problem?

We followed the description in this how to guide:
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/f04ce027-934d-2a10-5a8f-fa0b1ed4d88f
The only trick was to remember to select "Update deployed SDAs/SCAs that have any version" in step 1. This was the step that caused problem for our admins.
For compatability issues regarding JDBC drivers see SAP Note 831162.
We installed the ojdbc14.jar which so far has worked well against Oracle 10g.

JDBC, Oracle: access denied

I can load Oracle driver
Class.forName("oracle.jdbc.driver.OracleDriver");
But in this string:
String url = "jdbc:oracle:thin:@195.52.61.6:1521:ORCL";
java.sql.Connection con = java.sql.DriverManager.getConnection(url, "SCOTT", "TIGER");
happens exception:
java.security.AccessControlException: access denied (java.net.SocketPermission 195.52.61.6:1521 connect,resolve)
I have found in this forum many same messages. Can anybody explain problem?

Are you using an applet?

Problem in connectString = "jdbc:oracle:oci8@";

i get error in following lines.
=========================================
connectString = "jdbc:oracle:oci8@";
connection = DriverManager.getConnectionconnectString,"ORDMEDIADEMO",
"ORDMEDIADEMO");
===========================================
what should be there in connection string??? after @ , anything is to be specified??
I wrote my computer name(win2000server)...(p4.headquarter.local) .but it diden/t work.......plz help me.
thanks

Look in the JDBC documentation.
What is your service name?
You can use a string like:
@(description=(address=(host=your_machine.your_domain.com)(protocol=tcp)(port=1521))(connect_data=(service_name=your_service.your_service_domain.com)))
Or you can use one of the definitions in your tnsnames.ora file @my_sid

Jdbc:oracle:thin:@[host]:[port]:[sid] problem:

Hi all
When I try to make connection through this string jdbc:oracle:thin:@localhost:1521:orcl , It failed to connect to the database.
I am trying to connect to database through obiee 11.1.1.5 by jdbc connectivity.
Please tell me its solution.....
Thanks
Rizwan Ali

Hi,
The TNSNAME.ora that the OBIEE11g uses is insede the folder <OBIEE11g_HOME>\Middleware_Home\Oracle_BI1\network\admin
(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = IP address)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = orcl)))
Refer
http://123obi.com/2011/03/error-the-connection-has-failed-in-obiee-11g/
http://gerardnico.com/wiki/database/oracle/connect_descriptor
FYI: OTN Message:
1. If you just need one TNS alias, then copy the database connection descriptor from database tnsnames.ora file to the tnsnames.ora file under the BIEE directory:
[middleware home]/[oracle home]/Oracle_BI1/network/admin
2. You may also copy the entire tnsnames.ora file
3. Another alternative is to set the TNS_ADMIN environment varaible which would point to the directory where a tnsnames.ora file is located. This would need to be set as a System Environment variable in Windows or in the command shell if starting from a command-line. For Unix/Linux, it would need to configured in the user profile that owns the software or set explicitly in the shell if starting from the command-line. See Note 111942.1 Setting TNS_ADMIN Environment Variable for more information on adding this environment variable.
Thanks

Connection reset using JDBC Oracle thin Driver (towards 10g DB)

Hi we have a home-grown application and a Oracle 10g (10.2.0.1) database.
We created a scheduled servlet that gets a JDBC connection from a persistent connected cache (an OracleDataSource object registered using OracleConnectionCacheManager). The servlet runs every 15 minutes and runs the query "SELECT SYSTIME FROM DUAL" on 10g Database as XYZ user. The datapool was created yday on web-app and all queries ran successfully for about 5 hours after which it reported a connection reset error.
I can then conclude that we cannot keep the server session alive for the JDBC client by running frequent SQL queries.
We didnt get any messages on the DB server side that indicate the release of the session
Ultimately, we are struggling with reset connections from our applications that are
using the JDBC thin oracle driver; after a couple of hours of idle
connections, we receive the below error from the JDBC driver:
Jul 5, 2007 10:59:53 AM oracle.jdbc.driver.DatabaseError throwSqlException
WARNING: DatabaseError.throwSqlException(e): Unable to find ORA number from
exception Jul 5, 2007 10:59:53 AM oracle.jdbc.driver.DatabaseError

WARNING: DatabaseError.findMessage(errNum, obj): returned Io exception:

oracle.jdbc.driver.PhysicalConnection getWarnings
INFO: PhysicalConnection.getWarnings()
Any suggestions please ?

The code itself is fine; the problem is with one of:
1) the connection URL
2) intermediate networking
3) the database itself
1) your connection URL is "jdbc:oracle:thin:@127.0.0.1:1521:orcl"
- is Oracle really running on the default port, 1521
- is the installation SID really "orcl"
2) lots of possibilities, but only a couple are likely
- is TCP/IP configured and running on your host
- is there a persoanl firewall rpduct running? perhaps it's blocking the connection
3) Is Oracle running?
Is the listener running?

Jdbc oracle jdbc-thin driver subname

I am working on Windows 2000 environment, using oracle8i 8.1.7 JDBC-Thin driver for use with JDK 1.2.x. The oralce8i 8.1.7 database is on another linux box. I can access the linux box through its ip address, but not by its hostname since it's not accessiable by the dns server. In my code, in the JDBCUrl, I used ip address instead of the hostname, e.g. "jdbc:oracle:thin:@10.0.113.108:1521:ora1". But I got the error like: "java.sql.SQLException: Io exception: The Network Adapter could not establish the connection". If I add a entry in my working machine's hosts file to map the hostname, I can fix the problem. But I don't know if this is the solution, or there is other better solutions.
Thanks

Using a hosts file entry is a common solution for problem where the dns lookup does not contain an entry for a RDBMS server platform.
The real solution is to resolve this issue :
"where the dns lookup does not contain an entry for a RDBMS server platform."

OS authentication in Oracle 10g via jdbc:oracle:oci

I'm very much a newbie to Java / JDBC and I am trying, but failing, to connect with the database using OS authentication via jdbc, and hoping someone may help.
My questions are:
1. Is OS authentication supported for jdbc:oracle:oci with Oracle 10g ? I couldn't find a general statement of whether it works or not.
(NB.The only information I managed to find, on another forum, is that it should be supported but there is a bug and so it does not work, but the author did not post all of his/her platform details, so the bug may only affect his/her situation. )
2. If it is supported and works, could some one suggest what is wrong with my syntax . I could not find an example in any Oracle 10g/JDBC documentation.
The details are as follows: -
Database : - Oracle 10g Enterprise Edition 10.2.0.2.0 running on Solaris.
Development platform : - NetBeans 6.1, JDK 1.6.
Runtime environment: - JRE1.6 on Windows XP professional.
OPS$ authentication : - the OPS$ accounts have been set-up and we use these successfully for PL/SQL and SQL Plus access.
JDBC : - I can connect to the database with both jdbc:oracle:thin ( linking in ojdbc14.jar) and jdbc:oracle:oci by using username and password, so I know my JDBC library linkage is OK, eg. this works fine :
final String url = new String("jdbc:oracle:oci:" + uname + "/" + pword + "@" + environment);
where environment is the SID
I have trawled the Oracle documentation which tells me that OS authentication is not supported for Oracle 10g for the jdbc:oracle:thin driver, so I have tried to connect with jdbc:oracle:oci driver using the following code :
final String url = new String("jdbc:oracle:oci:/@" + environment);
final Driver driver = new oracle.jdbc.OracleDriver();
DriverManager.registerDriver(driver);
final Properties props = new Properties();
conn = DriverManager.getConnection(url);
but this gives the following error :
java.sql.SQLException: ORA-01017: invalid username/password; logon denied
Other info: - The tnsnames.ora file contains nothing but there are entries in the ldap.ora and sqlnet.ora files.

If you specify the SID/service_name in the url, you are attempting to connect via SQL*NET and REMOTE_OS_AUTHENT must be set to true in the database. If you are connecting from the same host the database runs on, then just leave the SID off and make sure the ORACLE_SID environment variable is set.
You can reproduce the same error you get in java with
sqlplus /@SID
