StardogException: Needs a boundary value

[jan.bjo...@gmail.com]

I am encountering the following error when trying to create a new database through the AdminConnection. Stardog version is 4.2 and using HTTP protocol.

Error occurs when calling the create() method below.

            adminConnection
                .disk("test")
                .set(ReasoningOptions.SCHEMA_GRAPHS, Collections.singletonList(TBOX_GRAPH))
                .set(ReasoningOptions.REASONING_TYPE, ReasoningType.SL)
                .set(ReasoningOptions.CONSISTENCY_AUTOMATIC, true)
                .create();

This is the stacktrace shown.

    ....

Any advice would be very helpful.

This test case works fine for me:

@Test
public void testCreateWithOptions() throws Exception {
try (Connection c = mConfig.connect();
AdminConnection aConn = c.admin()) {

aConn.disk("testdb")
.set(ReasoningOptions.SCHEMA_GRAPHS,
Collections.singletonList(iri("urn:g")))

.set(ReasoningOptions.REASONING_TYPE, ReasoningType.SL)
.set(ReasoningOptions.CONSISTENCY_AUTOMATIC, true)
.create();

aConn.drop("testdb");
}
}

What's the value of `TBOX_GRAPH`? Is there anything in `stardog.log`?

Cheers,

Mike

Let's see.

The value of TBOX_GRAPH is the IRI: <http://www.arkivverket.no/standarder/noark5/arkivstruktur/ontologyGraph>

I tried to enable snarl on Stardog and go back to using snarl for my connections and it worked as before. If I use http I get this error again.

Nothing out of the ordinary in the stardog logs.

Substituting in the IRI you've specified into my test case doesn't affect things, it still works as expected.

Can you create a junit test case that demonstrates the behavior you're seeing so that I can take a look?

Thanks.

The SNARL vs HTTP issue lead me to check my dependencies more closely. It seems that the problem was httpclient 4.5.2 being used while stardog expects httpclient 4.4. I have reworked my dependencies and now things seem to be in order.

Thank you for your patience. :)

Glad you figured it out and let us know what the issue was.
