Subject: RepositoryConnection.commit()
I'm using Sesame2 version 2.2.4 and SwiftOWLIM ver3.0.beta9. The
RepositoryConnection.setAutoCommit(false) seems to work. But the
RepositoryConnection.commit() seems not.
The code is like this:
...
SailImpl owlimSail = new com.ontotext.trree.owlim_ext.SailImpl();
owlse2 = new SailRepository(owlimSail);
RepositoryConnection con = owlse2.getConnection();
con.setAutoCommit(false);
for (String importURL : importURLs) {
try {
inUrl = new URL(importURL);
uriaddress = new URIImpl(importURL);
log.info("Importing URL: " + inUrl);
con.add(inUrl, importURL, RDFFormat.RDFXML,
(Resource) uriaddress);
log.info("Finished Importing URL: " + inUrl);
}catch (Exception e){
log.error("Failed to import "+importURL+" Associated error
message: "+e.getMessage());
con.rollback(); //something went wrong, roll it back.
}
}
con.commit(); //finalize the transaction
The above code leave the repository empty. However, if not using the
RepositoryConnection.setAutoCommit(false) and
RepositoryConnection.commit().
The repository is populated correctly.
Did I miss something here? Does the SwiftOWLim support the delayed commit?
Thanks,
Haibo
