Re: [topbraid-users] Debugging Sesame 2 repository connection error

[Scott Henninger]

Hello, Rich; Is it the case that the names of some of your property URIs start with numbers, such as <http://example.org/4321>?  In the past we have found that while this causes no problems in TopBraid and other back-ends, it can parse this in Sesame as:   <http://example.org/> "4321"^^xsd:string If you could check whether this is the case, we can take a closer look for how to address the problem. -- Scott On 3/23/2015 12:15 PM, Rich Keller wrote: I am having trouble creating a Sesame 2 repository connection with TBC-SE v4.6.2. When I establish the connection, I get a popup error window saying ‘unexpected error’, but the window is visible only for a second so I can’t make out any details. In the log, the following error is reported: !ENTRY org.topbraid.eclipsex 4 0 2015-03-23 09:57:03.571 !MESSAGE ERROR [Thread-16] (ParseErrorLogger.java:32) - [Rio fatal] Illegal predicate value: "4"^^<http://www.w3.org/2001/XMLSchema#integer> (573510, -1) So apparently a literal is being parsed in the position of a predicate. The full log message is below.  I don’t understand what queries TBC sends to Sesame or exactly what is being parsed when this error appears (in line 573510, so it seems). This makes it difficult to debug. Any suggestions?
