Connecting to Oracle using Java API

I'm fairly new to Oracle, but what I'm trying to do should be straight forward (at least that's what I thought). I'm simply trying to connect to an Oracle database using the latest java API (J2SE 1.4.1).
I downloaded JDBC OCI (type 2) driver form the Oracle Web site along with the appropriate DLL; however when I try to run the following two lines
String dbUrl = "jdbc:oracle:oci8:@test";
String user = "user";
String password = "password";
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection c = DriverManager.getConnection(dbUrl, user, password);
I get the following error message:
"java.exe - Entry Point Not Found
The procedure entry point slzsetevar could not be located in the dynamic link library oracore8.dll."
Please note that I am running under Windows 2000 Pro, have Oracle Client 8.1.5 installed, and am able to connect to the same Oracle database using ODBC and PowerBuilder native drivers.
Then I read somewhere that I should use 8.1.7 version of the Oracle client software, so I downloaded it from the Oracle Web site. However when I try to install it under Windows 2000 (by double-clicking on the setup.exe) nothing happens!!!
Any ideas?!

Sorry, I should have been more specific. The error message I was referring to shows up in a pop-up windows when I try to run the program. The actual java error message (that shows up in the command prompt window) is as follows:
"Exception in thread "main" java.lang.UnsatisfiedLinkError: C:\WINNT\system32\ocijdbc8.dll: The specified procedure could not be found

User permission issue in connecting to Oracle using java in Cent OS

Hi ,
I am facing a peculiar issue and since I am new to Cent OS, I hope somebody can help me.
I am using Cent OS 4.2 and I installed Oracle client 10.2 in cent os 4.2.
I am having a java application which connects to Oracle server in another Linux system using Oracle OCI driver which comes along with Oracle client
I have a user called user1 which belongs to group group1 as primary group and my application runs under this user user1.
This user is a member of oinstall group (which is the group for oracle uesr which has access to oracle client directories/files)
But when my application tries to connect to Oracle server, I am getting connectivity error saying "Oracle driver not found" or "cannot load libocijdbc10.so". All environment variables like ORACLE_HOME, PATH,CLASSPATH, LD_LIBRARY_PATH are set properly.
The permissions to Oracle folder/files are rwx for owner(oracle user) , rx for group(oinstall) and none for others
What we observed are
1. When the application is start under root user, it works
2. When we give rx permission to others, it works
3. When we make oinstall group as the primary group for my user user1, it works
My questions here
1. Why it is not working even though my user user1 is a member of oinstall group
2. Why it is working when I make oinstall as the primary group
3. Is there any difference in security policy of RHEL and Cent OS
4. How can I access libraries from multiple folders which created by different user and belongs to different groups, if this is the case
I never faced this issue in RHEL4
Hope some body can help me.

Sunil

i always got the compilation error Coud not find the database driver
i am using oracle9i and jdk1.5.0_04 and my classpath is C:\oracle\ora92\jdbc\lib\ojdbc14.zip;C:\oracle\ora92\jdbc\lib\orai18n.zip
i am realy stuck with this so any one can help me with this probelm
thanks alot,

thanks for your reply,
yes i changed the server name and i verified the location of the JDBC driver file(s) on my computer. any way i solved my problem.
you know there was a misunderstanding in what you mean by classpath, i thought that i have to change the classpath from control panel>system>advance>enviroment variable
and then select classpaht and edit it. i was doing this but this is didn't work.
then i don't know why i did that
i went to java program and select my project,right click on it and then select properties>java build path and then select "add external Jars" button and then i simply choose them and add them to my project. and finaly it worked.
thanks alot

How to use java api for function activity in embed oracle workflow?

because i can't install standalone oracle workflow successfully.
pls tell me how to use java api for function activity in embed oracle workflow?
are there some patch or pulg-in package?
ths a lot...........

The Java Function Activity Agent is not certified for Oracle Workflow embedded in Oracle Applications. Installing standalone workflow should be a lot easier than what you have found, although it looks like you did hit a Pentium 4 issue with the Oracle Universal Installer. I suggest you contact Oracle Support or Oracle Consulting for assistance.

You must not have the complete IFS_BASE_CLASSPATH defined in your CLASSPATH environment variable. The easiest way to do this is to type ". ifsenv.sh" on Solaris (or run ifsenv.bat on NT). Then you can invoke java like this:
java -classpath $CLASSPATH:$IFS_BASE_CLASSPATH ...
(your standard JDK classes should already be in the CLASSPATH; append our classpath to it)

How to build a small application using Java API

Hai expertise,
I want to retreive MDM repository info using JAVA API, i am following these blogs:
/people/andreas.seifried/blog/2006/03/26/performing-free-form-searches-with-mdm-java-api
/people/udi.katz/blog/2005/08/21/retrieving-data-from-mdm-server-using-the-mdm-java-api
/people/udi.katz/blog/2005/07/17/mdm-connectivity-to-java-application
where to get the jar and sda files to build the application??
In Developer Studio.. Windows -> Preferences -> Java -> Classpath variables. Is this the only place where we need to give the jar file path??
Are there any other configurations to do(except setting container variable to MDM4J jar file) to connect my java application to MDM repository???
Regards,
Chand.

Hi Govada,
(1)You need to add the MDM4j and other JAR files at:-
right click on project -> Java Build Path -> Libraries -> Add External JARs
(2)If the project is Web Dynpro project one
then right click on project -> Web Dynpro Reference -> Library Reference -> and add sap.com/com.sap.mdm.tech.mdm4j
Are you using JAVA API 1 or 2???
Thanking you

Hi,
I want to find the installed JREs in windows using java. I couldn't fine any java API. So I am using the below code to fetch the JRE list from windows registries & parse the returned collection to know the installed JRE.Why? If you are running java you already have a JRE. So why not just use it?
>
String key = "HKEY_LOCAL_MACHINE\\SOFTWARE\\JavaSoft\\Java Runtime Environment";
Runtime.getRuntime().exec(
"reg query " + "\"" + key + "\"");
Is it legal to retrieve the installed JREs in this way? Legal? It is OS specific, and to a certain extent dependent on vendor and what the vendor wants to do. Could also be impacted by permissions. Other than that it is ok.
I am feeling like its a type of hacking. So I couldn't decide whether this is legal (recommended) way of using. Does anybody can answer me. I can see the similar posts in google. Somebody suggests this way & somebody suggests to use preference API which is similar to this. Appreciate your help.Preferences won't work. It doesn't allow access to the registry in general, only a part of it. There are discussions in the JNI forum about retrieving VM versions. Prior to actually using the VM though.

Where's the Oracle Forms Java API documentation for 11g?

Hi,
Can anyone point me in the direction of the Oracle Forms Java API documentation?
The only thing I can find is this: http://www.oratransplant.nl/1012jdapiDoc/oracle/forms/jdapi/JdapiModule.html but this seems to be for 10.1.2 and it doesn’t correspond to the version I’m using (11.1.1.3).
Help appreciated,
Donal.

i couldn't find the api either however if you implement the class you will simply get compiler errors explaining what you left out.

Create group in OID using java api

Hi all!
I need to create group in OID using java api. Java api documentation contains examples for creating users but not for groups. I search oracle.com (and google) and didn't find any hint.
Anybody know the way?
thank you.

Andrew,
a group is created like any other entry in OID. You need to specify the dn, objectclass(es) and (mandatory) attributes.
e.g.
objectclass=groupOfUniqueNames
with
uniquemember=cn=orcladmin, cn=Users, dc=de,dc=oracle,dc=com
as an example take a look at
cn=iASAdmins, cn=Groups,cn=OracleContext,dc=de,dc=oracle,dc=com
to see the schema (data) for groupofuniquenames you can either use ODM or query the directory server
ldapsearch -p 3060 -b "cn=subschemasubentry" -s base "objectclass=*"
regards,
--Olaf
