I created a simple Plugin that uses Teneo, Hibernate and mySql.
When I run my unit test directly on the class that does the database
persistence operations, all tests pass.
When I run my test as a plugin then I get an error that the Hibernate
can not find the mySql driver. The Unit test uses Junit3 and in
headless mode.
I have the mySQL plugin from the Eclipse web site as a dependency.
I have the mySQL JAR in a lib directory and set the classpath to point
to it. I tried all kind of combination, but I can not make it work.
Here is the code for setting the hibernate:
final Properties teneoProperties = new Properties();
teneoProperties.setProperty(PersistenceOptions.USE_MAPPING_F ILE, "true");
final Properties hibernateProperties = new Properties ();
hibernateProperties.setProperty(Environment.DRIVER,
"com.mysql.jdbc.Driver");
hibernateProperties.setProperty(Environment.USER, "root");
hibernateProperties.setProperty(Environment.PASS, "dba");
hibernateProperties.setProperty(Environment.URL,
"jdbc:mysql://picardv3.accenture.com:3306/yigaldb");
hibernateProperties.setProperty(Environment.DIALECT,
org.hibernate.dialect.MySQLInnoDBDialect.class.getName());
// Initialize dataStore
String datastoreName = "domain";
dataStore = HbHelper.INSTANCE.createRegisterDataStore(datastoreName);
dataStore.setEPackages(new EPackage[] { DomainPackage.eINSTANCE });
dataStore.setPersistenceProperties(teneoProperties);
dataStore.setHibernateProperties(hibernateProperties);
dataStore.initialize();
Any ideas how to fix this?
Thanks
Yigal

Hi Yigal,
Which classpath property did you point to the mysql jar?
For a plugin project this should be specified in the META-INF/Manifest.MF. So for a plugin project
you should not use the classpath project properties directly. For a plugin project the classpath
from the manifest.mf is added to the project properties so it works for both a normal junit run and
for a plugin run.
btw, I don't think that you need to use the mysql plugin for just running teneo/hibernate/mysql
(maybe you have other reasons), the jar file would be enough.
