hi everybody,
  I try to use oracle oci driver to connect oracle database with java servlet, but at first, I try to get the local machines' all TNSNAMES entries from \orahome\transname.ora, I implemented it by parsing this file, but as you know, it is not good, because different machine has different orahome,anybody have a good idea to get those entries and put them into a JComboBox?
thanks

You could check the operating system, if NT get ORACLE_HOME via registry, then parse file.  If UNIX, get ORACLE_HOME via env variable, then parse file.

Hope this helps.

lisayan,

OK...what a lessoned learned.  I had some time to kill so I think I can help out.  I found a package that allows access to the registry.  I downloaded the zip file.  But the package is called JNI Registry.  I can return email you a copy.  My email is kmhasselstrom@tasc.com.  After setting up the class names it was very easy to traverse the registry.  

The code to get my Oracle home on my windows 2000 box is posted below.  I have several Oracle installs so you may want to write some code to read all the Oracle homes and get all the values.  Then look for several TNS names etc....

If you get a java.lang.path error try this url for help:

Hope this helps...

import java.util.*;

import com.ice.jni.registry.*;

public class WinRegAccess extends Object {


public static void main(String[] args) throws RegistryException{

 RegistryKey reg = Registry.HKEY_LOCAL_MACHINE.openSubKey("SOFTWARE");
 RegistryKey reg2 = reg.openSubKey("ORACLE");
 RegistryKey reg3 = reg2.openSubKey("HOME2");

 System.out.println(reg3.getStringValue("ORACLE_HOME"));

}
