private static java.lang.ClassLoader makeClassLoader()

setUp

protected void setUp()
              throws java.lang.Exception

setUp in class junit.extensions.TestSetup

Throws:

java.lang.Exception

tearDown

protected void tearDown()
                 throws java.lang.Exception

Overrides:

tearDown in class BaseJDBCTestSetup

Throws:

java.lang.Exception

setThreadLoader

public static void setThreadLoader(java.lang.ClassLoader which)

Force this thread to use a specific class loader.

Parameters:

which - class loader to set
