Unable to create weblogic connection pool

Posted on 2004-08-08
Last Modified: 2008-02-01
I'm getting the following error while creating weblogic connection pool.
I'm using weblogic 6.1 on Solaris and Oracle 9i database. Please help me out for resolving this.


weblogic.common.ConnectDeadException: failed to make new pool connection: weblogic.common.ResourceException:
 Could not load 'oracle.jdbc.driver.OracleDriver

 If this is a type-4 JDBC driver, it could occur if the JDBC
 driver is not in the system CLASSPATH.

 If this is a type-2 JDBC driver, it may also indicate that
 the Driver native layers(DBMS client lib or driver DLL)
 have not been installed properly on your system
 or in your PATH environment variable.
 This is most likely caused by one of the following:
 1. The native layer SO, SL, or DLL could not be found.
 2. The file permissions on the native layer SO, SL, or DLL
    have not been set properly.
 3. The native layer SO, SL, or DLL exists, but is either
    invalid or corrupted.

Looks like you've done some reasonable amount of research before posting it. That looks good. Can you make sure if the driver-class is in the class-path (Weblogic's class-path)?

Are you creating the connection pool programmatically? AFAIK WebLogic comes with its own set of drivers, even for Oracle (although this is true for 8.1, not sure about 6.1 version) why don't use use them? Also can you post the output of this:

The previous URL is

and one more thing is, following are the some of the details about the versions of software i'm using.

1.Oracle 9.2.5 (64 bit version)
2.JVM 32 bit version on Solaris 5.8

As i'm using 32 bit JVM, even if i have Oracle 64 bit version, if i'm connecting using JDBC driver i should used 32 bit oracle libraries only... meaning i should have lib32 in my LD_LIBRARY_PATH, not lib.
