Unable to connect to DB using OCI

Question

Hi,
I am unable to connect using the oci driver to the database. The
thin driver does not pose any problem
I compile without a hitch, but when i run it, it gives the
following dump:
C:\jdk1.2.2\bin>java orcltest
Exception in thread "main" java.lang.UnsatisfiedLinkError: no
ocijdbc8 in java.l
ibrary.path
at java.lang.ClassLoader.loadLibrary
(ClassLoader.java:1249)
at java.lang.Runtime.loadLibrary0(Runtime.java:470)
at java.lang.System.loadLibrary(System.java:768)
at oracle.jdbc.oci8.OCIDBAccess.logon
(OCIDBAccess.java:202)
at oracle.jdbc.driver.OracleConnection.<init>
(OracleConnection.java:156)
at oracle.jdbc.driver.OracleDriver.getConnectionInstance
(OracleDriver.ja
va:231)
at oracle.jdbc.driver.OracleDriver.connect
(OracleDriver.java:208)
at java.sql.DriverManager.getConnection
(DriverManager.java:457)
at java.sql.DriverManager.getConnection
(DriverManager.java:137)
at orcltest.main(orcltest.java:21)
C:\jdk1.2.2\bin>
The code I have written is:
try {
Class.forName ("oracle.jdbc.driver.OracleDriver");
} catch (ClassNotFoundException e) {
System.out.println(e.getMessage());
try {
DriverManager.registerDriver( new
oracle.jdbc.driver.OracleDriver() );
} catch (SQLException e) {
System.out.println(e.getMessage());
Connection conn =
DriverManager.getConnection("jdbc:oracle:oci8:@:karishma",
"user", "passwd");
Karishma is the TNS-service name defined in the tnsnames.ora.
This is driving me nuts. I have set the path and classpath vars.
The file oci804jdbc.dll is in [ORA_HOME]\bin, and PATH points to
that directory.
Any suggestions are most welcome and badly needed!
Thanx

Answer 1

I had the same problem before.
And maybe this is the cure...
Check that you use the jdbc-drivers(classes111.zip) fwr 8.0.4
and not the ones for 8.1.5. I think they use different dll's. In
an 8.1.5 installation there is a file named ocijdbc8.dll and I
think that the one for 8.0.4. uses the one you mentioned...
