Anybody??
I can't explain what is going on. I am almost sure that the problem is with the
generated mapping file, but why???
Could you help me, please??
Thank you.
Vivi.

Hello,
I am trying to use D2R Server Update, but without success.
More specifically,
I have installed d2r server update on windows XP and i have established the
database example iswc in mysql .
After that i run the following command that creates successfully the mapping
file iswc.n3:
generate-mapping -u root -o iswc.n3 -b http://localhost/8080/
jdbc:mysql://localhost/iswc
After that i run the following command:
d2r-server -p 8080 iswc.n3 and i open my browser to the following address:
localhost:8080.
>From there, i can access localhost:8080/snorql where i am supposed to query
>(select/construct) and update (delete/insert) my database.
I can query(execute select and construct queries and i suppose that i can also
execute ask and describe) my database but can't modify it.
When i am trying to run
the following query:
MODIFY DELETE {
?person <http://localhost:8080/vocab/resource/persons_Phone>
'222-222-2222'
}
INSERT {
?person <http://localhost:8080/vocab/resource/persons_Phone>
'310-448-8794'
}
WHERE {
?person <http://localhost:8080/vocab/resource/persons_FirstName>
'Yolanda'
}
i get the following response:
HTTP ERROR: 500INTERNAL_SERVER_ERROR
RequestURI=/sparqlupdatePowered by Jetty://
and in the prompt i get:
18:36:41 WARN Servlet :: Internal server error

I haven't changed anything in the generated mapping file. I can dispose it if
it is required.
When i use the example
mapping file
http://www4.wiwiss.fu-berlin.de/bizer/D2RQ/example/mapping-iswc.n3 there is no
problem. I can modify the database without any problem.
What is going on?? Could you help me??
Thank you in advance.
Vivi.
