Hello,

I have updated clover from version 2.1 to 2.2.1. I copy DBF tables into a MySql database.  
In the 2.1 version I have no error but in the 2.2.1 version I get the following error :

```auto
DEBUG [WatchDog] - DBF_DATA_READER ...OK
DEBUG [WatchDog] - MYSQL_WRITER ...OK
INFO [WatchDog] - [Clover] phase: 0 initialized successfully.
INFO [WatchDog] - Starting up all nodes in phase [0]

        at org.jetel.graph.Node.run(Node.java:366)
        at java.lang.Thread.run(Thread.java:595)

```

what I understand is that a java class is missing to convert a numeric value to a String, when I give a look to the data I have numeric that I copy into MySql in a Varchar column.

I tried on the 2.3.3 version but I get exactly the same error.

Is there a way to make new version working with DBF\_DATA\_READER or should I keep my working 2.1 version for DBF loading and the 2.2.1 version for XLS loading ?

Thanks for your reading.

Regards,

Hi,  
when you run graph, javolution.jar (included in CloverETL package) has to be in classpath while we use it when parsing strings.

I have tried to include the javolution.jar package it seams to resolve my problem but I get an other error.

```auto

```

I don’t realy understand what’s wrong in this case.  
Should I understand that there are null values in the DBF tables and I need to treat it with the graph or it is a java object that is null and it crashed my clover data loading ?

Thanks for your help.

Hi,  
aren’t your data very large. I suppose that your record is greater then expected size. Pls check [http://wiki.clovergui.net/doku.php?id=c … \_constants](http://wiki.clovergui.net/doku.php?id=compile%5Ftime%5Fconstants)

Hello,

I tried to extract and after modification of the parameter file to recompile the jar with a compressing tool as WinRar witch is file roler under gnome desktop but the generated jar file doesn’t work at all.  
I think I need to use a special command line to extract and to recompile the jar.

Can you tell how to do it or where to find some help on jar file ?

Thank you

Tchoua
