Test Connection Error: PostgreSQL and XESame

Hello,

  I am trying to use XESame to convert the data in the database.  Here is my configuration.

1) Windows 7 64-bit
2) Database Server is PostgreSQL 8.4

I open the Odbcad32.exe in the %systemdrive%\Windows\SysWoW64 folder;
I created a DSN name ReviewDB. When I click Test button in the ODBC setup window, the connection was succesful.

When I go back to XESame to create new connection.

I enter following information

URL = jdbc:odbc:ReviewDB
JDBC Driver = sun.jdbc.odbc.JdbcOdbcDriver
JDBC Driver Location = Blank  (Do I need to specify driver here?)

When I click Test Connection I got this error
Sorry, but the test failed because the URL could not be found:
[Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application.

I suspect that the PROM I have is running on 32-bit because it's installed in Program Files (x86) folder. 

Do you have any suggestion on how to fix this problem?

    Hi Deen, welcome aboard!

    The set-up you tried might work but is a bit of a detour since you connect from JDBC to ODBC and then from ODBC to PostgreSQL. The problem you are encountering is caused by XESame running in 64-bit mode while you specified the ODBC driver in 32 bit mode. If you want to use this way then you need to set up an ODBC connection in the same 'bit version' as you run XESame.

    The better solution however is to use a PostgreSQL JDBC driver (http://jdbc.postgresql.org/). Especially for larger data sets the performance difference is significant.
    In XESame you need to set the JDBC driver location (point to the jar file you downloaded from the URL above). Of course you also need to update the URL and JDBC Driver name accordingly. More information can be found in the driver documentation.

    Let me know if this works!!!

    Hi Joos,

    Thank you very much.  Here is how to connect XESame to PostgreSQL on windows

    URL to Database = jdbc:postgresql://localhost/<databasename>?user=<username>&password=<password>

    JDBC Driver = org.postgresql.Driver

    JDBC Driver Location = <path to the postgresq driver> download from http://jdbc.postgresql.org/download.html

    Do we have a wiki setup for XESame.  I can update this information to the document.

    Hi Deen,

    Thank you for posting the JDBC connection details!!!
    I'm also glad that it works now.

    There is a wiki page about XESame (http://www.processmining.org/xesame/start) but I'm not sure if you can edit the page. Otherwise I will add it later today.
