JDK1.2Beta4-G: Unable to load third party JDBC Driver *URGENT*

gordon.jackson@east 1998-05-28

This seems to be a continuation of an earlier reported problem:

4140992 -ClassFormatError when loading the Connect JDBC driver for SQL Server

However, this is a bit more perplexing. For starters, when I execute

public class Reg {
public static void main(String[] argv) throws Exception {
Class.forName("oracle.jdbc.driver.OracleDriver");
}
}

-- beta4-G works

/js/files/JDK1.2Beta4-G/solaris/bin/java -cp .:$CLASSPATH Reg
Warning: JIT compiler "none" not found. Will use interpreter.

-- beta3 works

/js/files/JDK1.2Beta3/solaris/bin/java -cp .:$CLASSPATH Reg
Warning: JIT compiler "none" not found. Will use interpreter.

-- beta3/verify works

/js/files/JDK1.2Beta3/solaris/bin/java -verify -cp .:$CLASSPATH Reg
Warning: JIT compiler "none" not found. Will use interpreter.

(notice that the JIT is disabled - just in case...)

However, when I run the JDBC tests/harness I get the following:

-- beta4-G does not work
[...snip...]
DriverManager.getConnection("jdbc:oracle:oci7:@JDBCTEST")
DriverManager.initialize: jdbc.drivers = oracle.jdbc.driver.OracleDriver
DriverManager.Initialize: loading oracle.jdbc.driver.OracleDriver
DriverManager.Initialize:
load failed: java.lang.ClassNotFoundException: oracle/jdbc/driver/OracleDriver
[...snip...]

-- beta3 works

(again, the JIT has been turned off to protect the innocent)

The JDBC Driver in question here can be found in

/net/jst2705.east/oracle/7.3.4/product/jdbc/lib/classes111.zip
(oracle/jdbc/driver/OracleDriver.class)

Alas, I do not have a simple test case, and it takes a little work to get the JDBC tests/harness running. However, if you need to run the JDBC Tests in order to reproduce this, then by all means let me know and I will be glad to assist.
