RDFBean queries don't work with the Sesame HTTPRepository #42

Closed timowest closed 11 years ago

timowest commented 11 years ago

RDFBean creates Sesame queries programmatically, but those can't be serialized when the HTTPRepository type is used.

That is probably my case because I use HTTPRepository.

I will take a look at this in the weekend.

marek-surek commented 11 years ago

thank you

timowest commented 11 years ago

Should work better now. Could you try?

marek-surek commented 11 years ago

Sorry for late reply... today Im bit without internet. I run the problematic thing in our app and it worked as expected. Therefore I think we can consider it as fixed. Thank you. Tommorow I'll test it intensively. If any problem appear, I will inform you.

In all situations I've tested, it worked. I close this ticket.
