VerifyError when using hxtt acess and dbf together on some JVMs |

Hi,
I have a sample application that contains one class with the main method that has these lines of code inside, nothing more:
Class.forName("com.hxtt.sql.access.AccessDriver");
DriverManager.getConnection("jdbc:access:/e:/work/projects/files/db1.mdb");
On some environments, for example on win xp sp2, with Sun's jdk "Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_03-b07)", when I run this application I get
Exception in thread "main" java.lang.VerifyError: (class: com/hxtt/sql/access/l, method: signature: (Lcom/hxtt/concurrent/v;Ljava/util/Properties;Lcom/hxtt/sql/common/o;)V) Incompatible argument to function
at com.hxtt.sql.access.EmbeddedDriver.connect(Unknown Source)

at com.intellij.rt.execution.application.AppMain.main(AppMain.java:78)
Note that this happens ONLY if I have both Access_JDBC30.jar and DBF_JDBC30.jar in the classpath. And yes, as you can see, I am not using the dbf driver, but having it in the classpath makes the access one throw this error.
Any kind of assistance would be of great help. We have the dbf driver and we are planning on getting the access one, but we need to use them together so this is a roadblock for us.
Let me know if you need more details.
Thx,
Andrei

1st solution: Download and update DBF package and Access package at the same time.
2nd solution: Download and update Common Package, DBF Core package, and Access Core package at the same time.

Unfortunately that only changes the error to
Exception in thread "main" java.lang.NoSuchMethodError: com.hxtt.sql.cv.a(ILjava/lang/String;Ljava/util/Properties;)Lcom/hxtt/concurrent/v;

Please check and make sure all of your package files have the same date. Maybe one of your package is an older package.

They have the same date, 2006-03-29. The files names are DBF_JDBC30.jar Access_JDBC30.jar.

There aren't many settings I can look at :(
Btw, I can duplicate this on a number of machines, though not all of them. I haven't yet identified the rule by which to make this happen, except that it happens only when I have both the dbf and the access jar in the classpath.
Thx,
Andrei

Please paste your command. I'm still thinking that maybe you're using an older dbf or access package although you have just download the latest package.

Passted all tests with JDK1.5.0_03-b07 on Win xp sp2 too.

Figured it out |

It was our (silly silly) mistake. We had more versions of the access driver in our classpath.
Thank you very much for the outstanding support you've offered.
