HXTT Paradox
Invalid paradox file header
Eduardo Kruger
2005-09-23 00:00:00
We acquire recently the HXTT-Paradox package for the access of Paradox bases with a java application using JDBC.
I'm having some problems and perhaps you can help me.

When I execute any statement on a table using , I receive the message error:

"Failed you load table TRLI.For more information, please uses SQLException.getNextException() "

In getNextException() I got the message:
"Invalid paradox file header ".

Any operation (SELECT, INSERT, UPDATE) that I try to execute on this table, occurs the same error. I tried to update the indexes (REBUILD ALL ON TRLI) but also occurs the same error.

What can be causing this error?

Thanks and regards,
Eduardo Kruger

Dear Eduardo Kruger,

>Invalid paradox file header
It means that HXTT Paradox checked and found your paradox database should have some incorrect information in file header so that it stopped to operate that file. You can use paradox tool to repair, or let us help you repairing manually. If many of your paradox files reports the same exception, that means your Paradox applications have wrote incompatible mark in paradox file header, and we will modify HXTT paradox to skip such a verification check according to your paradox sample. You can email your paradox sample to

With best regards,

Dear Daiwei,

I have other legacy BDE-Delphi application that write on this paradox database too and problably this application modify in some way the file header of some files (.DB). But a really need to access this files with HXTT Paradox and avoid this exceptions.
It's going to be a great help for me if you can modify HXTT paradox to skip these exceptions.
I'm sending to you ( one paradox sample file where i'm always having these type of exceptions ("Invalid paradox file header"). Any operation executed on this file, will generate the error. You can see the exception executing a simple SELECT statement on the file, ok.

Thanks and regards,
Eduardo Kruger.
