I have a client that I implemented nightly batch load process for years ago using the dataloader command line interface.  It has worked every night for 7 years without an issue.  They now need to upgrade the server it is running on and at the same time want to upgrade dataloader.  They installed dataloader 34.0 and I cannot get it to connect to salesforce and I am starting to think there is a bug in dataloader 34. 

Here is the error:

The error is java.net.UnknownHostException: C

Here is the relevent bean in the process-conf.xml file:
 

        Test upsert
        
        
            
        
    

The reason that I think there is a bug in DL 34 is because I also have DL 30.0.0 installed on my machine and when I change this line in the process.bat file:
 

..\Java\bin\java.exe -cp ..\dataloader-34.0-uber.jar -Dsalesforce.config.dir=%1  com.salesforce.dataloader.process.ProcessRunner %PROCESS_OPTION%

to this:
 

..\Java\bin\java.exe -cp ..\dataloader-30.0.0-uber.jar -Dsalesforce.config.dir=%1  com.salesforce.dataloader.process.ProcessRunner %PROCESS_OPTION%

and keep everything else the same, I don't get the  java.net.UnknownHostException: C  error.  

Can anyone shed any light onto this?

Thanks

The error is java.net.UnknownHostException: C

Here is the relevent bean in the process-conf.xml file:
 

        Test upsert
        
        
            
        
    

The reason that I think there is a bug in DL 34 is because I also have DL 30.0.0 installed on my machine and when I change this line in the process.bat file:
 

..\Java\bin\java.exe -cp ..\dataloader-34.0-uber.jar -Dsalesforce.config.dir=%1  com.salesforce.dataloader.process.ProcessRunner %PROCESS_OPTION%

to this:
 

..\Java\bin\java.exe -cp ..\dataloader-30.0.0-uber.jar -Dsalesforce.config.dir=%1  com.salesforce.dataloader.process.ProcessRunner %PROCESS_OPTION%

and keep everything else the same, I don't get the  java.net.UnknownHostException: C  error.  

Can anyone shed any light onto this?

Thanks
