I'm following this tutorial here to insert a new resource into Fuseki
's dataset, but I'm getting this error:
the method format(String, Object[]) in the type String is not applicable for the arguments (String, String)
This is the code:
import java.util.UUID;
import com.hp.hpl.jena.query.QueryExecution;
import com.hp.hpl.jena.query.QueryExecutionFactory;
import com.hp.hpl.jena.query.ResultSet;
import com.hp.hpl.jena.query.ResultSetFormatter;
import com.hp.hpl.jena.update.UpdateExecutionFactory;
import com.hp.hpl.jena.update.UpdateFactory;
import com.hp.hpl.jena.update.UpdateProcessor;
/**
* Example connection to Fuseki. For this to work, you need to start a local
* Fuseki server like this: ./fuseki-server --update --mem /ds
*/
public class FusekiTest {
/** A template for creating a nice SPARUL query */
private static final String UPDATE_TEMPLATE =
"PREFIX dc: <http://purl.org/dc/elements/1.1/>"
+ "INSERT DATA"
+ "{ <http://example/%s> dc:title \"A new book\" ;"
+ " dc:creator \"A.N.Other\" ." + "} ";
public static void main(String[] args) {
//Add a new book to the collection
String id = UUID.randomUUID().toString();
System.out.println(String.format("Adding %s", id));
UpdateProcessor upp = UpdateExecutionFactory.createRemote(
UpdateFactory.create(String.format(UPDATE_TEMPLATE, id)),
"http://localhost:3030/ds/update");
upp.execute();
}
}
How can I fix that error?
This issue is common when the java project version is 1.4.
It's a common problem that the project Java version is set to 1.4 or 1.6 by default in the template by the IDE. You should make sure that you have the correct Java version set on your project.
Eclipse:
Right click project -> Properties -> Java Build Path -> select JRE System Library click Edit and select JDK or JRE after then click Java Compiler and select Compiler compliance level to 1.8
IntelliJ
Menu -> File -> Project structure -> project SDK
Netbeans
This assumes that you installed JDK 1.6 and NetBeans knows about this.
The JDK 1.8 must already have been supplied to NetBeans. To do that you got to menu -> Tools-> Java Platform Manager.
