Yesterday, it was configured to Jena 2.4.0,mysql database version of 5.1.42-COMMUNITY,JDK version for 1.6.0,mysqldriver mysql-connector-java-3.1.14;

And according to the resources on the network to write an example, resulting in a problem, the program in debug to

To create a model builder using database connection parameters

Modelmaker maker = Modelfactory.createmodelrdbmaker (conn);

Create a default model named Myontology

Model Defmodel = Maker.createmodel ("Myontology");

In two sentences, you cannot create a model from Maker.createmodel;

Then wrote some debug debugging, one is the use of Java interface to access MySQL, test success, that the Java and MySQL connectivity between the right, then the problem appears on the Jena;

After updating Jena to version 2.6, find the problem solved.

Experience:

To do this research, found that the use of these open source software and APIs, the most likely problem is the version compatibility problem, previously encountered protege and Graphviz version compatibility problem, and once encountered this problem, often take a long time, Because the first suspects are often the ones who know little about themselves.
