Eclipse,hibernator-Not Create New Connection

[Sam]

I am having problem in integrating Eclipse2.1.0 with hibernator-0.9.5.zip. I unzipped it in Eclipse plugin. I tried creating new Connection to Oracle 9i. I am trying to add a new connection by entering values in the GUI, but new connection does not get created. However, I can connect to Oracle using SQL Plus, and from Java program using the url and class name below.

I am using:

Connection Name= webdev
driver_class=oracle.jdbc.driver.OracleDriver
url=jdbc:oracle:thin:@dbtest.internal.myworld.com:1521:webdev
username=xxx
password=xxx
dialect=net.sf.hibernate.dialect.OracleDialect
Driver File Name = classes12.jar

I am having the following error in Eclipse Log:
!ENTRY org.eclipse.ui 4 4 Aug 06, 2003 14:40:40.25
!MESSAGE Unhandled exception caught in event loop.
!ENTRY org.eclipse.ui 4 0 Aug 06, 2003 14:40:40.25

The code tells me that the dialect is null?! Very strange. I will tighten the validation around this area though.

Any luck getting further?

It looks likes caused by following method.

NewConnectionWizard.java:
  public void performFinish() {
    ...
    int index = dialect.getSelectionIndex();
    if(index != -1)
        initialData.setDialect(dialect.getItem(index));
  }

If the dialect was inputed from keyboard not by combo select box,
the index become -1.  So the dialect in initialData stay null.

How about this fix?

NewConnectionWizard.java:
  public void performFinish() {
    ...
    int index = dialect.getSelectionIndex();
    if(index != -1)
        initialData.setDialect(dialect.getItem(index));
+   if (initialData.getDialect() == null) {
+       initialData.setDialect(dialect.getText());
+   }
  }
