Hi! If I execute a hql query, I get always the following exception: org.hibernate.hql.ast.QuerySyntaxException: MyEntity is not mapped [select e.myAttribute from MyEntity e] I don't have any idea, what I'm doing wrong :-(. I did the follwing things: 1) Set up an empty projekt 2) Create a new hibernate configuration file with the wizard 2.1) I set the database dialect to "Oracle" 2.2) I set the username, password and connection url with the correct values. I set Driver Class to "oracle.jdbc.driver.OracleDriver". I let all other fields empty. 3) Create a console configuration 3.1) Add the oracle driver jar to the classpath 3.2) Add the folder, which contains the entity class files, to the classpath. After that, I can do the following things: 1.) Open the hibernate configuration view 1.1) I see an entry for my projekt. If I click that entry, the node is unfolded an I see all the schema's of my database. If I click on "my" schema, I see all tables. If I click on a table, mostly nothing happens. Sometimes I can see the attributes of a table, but mostly not. 2) Open the HQL Editor and the Hibernate Query Result view. 2.1) Select my Projekt 2.2) Enter the query select e.myAttribute from MyEntity e 2.3) I see the error message which is printed above in the result view. 2.4) Enter the query select e.myAttribute from MySchema.MyEntity e 2.5) I see the error message which is printed above in the Result view (only the query is different in the error message) Why doesn't the stuff work? I use Oracle 10g, the JBossIDE for Eclipse (Build 2.0.0.Beta2), JBOSS 4.0.5GA and EJB 3.
