Subject Re: Exception in ServerPagesGenerator.generate(): java.lang.RuntimeException: Could not get the datasource NullPointerException
Date Fri, 22 Aug 2008 13:12:45 GMT
Hi Kasim,

I do not have a lot of experience with xsp, but the problem appears to 
be in your xsp file.

index_xsp.java:350

Could you perhaps paste the line here on the list, so we can have a 
look, or attach your xsp file if it's not too big.

Regards,

Jeroen Reijn
