Java.lang.UnsatisfiedLinkError: no ocijdbc8 in java.library.path

Question

hi,
i am trying to connect to an oracle 8.1.7 database from my application running on tomcat 4.0.3 / jdk1.4 /windows nt.
using the thin jdbc-driver (classes12.zip) everything works fine.
when i try using the oci8-driver, i get an error-message saying:
java.lang.UnsatisfiedLinkError: no ocijdbc8 in java.library.path
i have the oracle-client installed on my machine.
the ocijdbc8.dll can be found in D:\server\oracla81\bin
the environment-variables PATH, CLASSPATH, LD_LIBRARY_PATH (i'm not sure if this has any meaning on nt) all point to this directory.
i start tomcat using the following option: -Djava.library.path="D:\server\oracla81\bin"
my application can see this variable:
System.out.println("java.library.path: "+System.getProperty("java.library.path"));
prints out the correct value.
then i try to load the library by myself:
try {
System.loadLibrary("ocijdbc8");
System.out.println("Successfully Loaded");
} catch(Exception e) {
System.out.println("LD_LIBRARY_PATH is not properly set");
e.printStackTrace();
everything works fine! the library is loaded!
finally i try to connect to the database and the application throws the mentioned exception:
lang.UnsatisfiedLinkError: no ocijdbc8 in java.library.path
     at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1410)
     at java.lang.Runtime.loadLibrary0(Runtime.java:772)
     at java.lang.System.loadLibrary(System.java:832)
     at oracle.jdbc.oci8.OCIDBAccess.logon(OCIDBAccess.java:228)

     at oracle.jdbc.driver.OracleDriver.getConnectionInstance(OracleDriver.java:365)
     at oracle.jdbc.driver.OracleDriver.connect(OracleDriver.java:260)
any help would be appreciated.
thanx in advance,
frank.

It is probably JDK 1.4 that causes the problem. I was able to get strange errors with that version of the JDK with code that worked fine using 1.31.
