    Reverse engineering - Could not obtain connection metadata

    dlibke Nov 18, 2006 1:40 PM

      I am using JBoss IDE 1.6.0 GA and JBoss 4.0.2 GA and Oracle 10g.

      Using the new connection wizard, I generated this hibernat.cfg.xml file:

      <?xml version="1.0" encoding="UTF-8"?>
      <!DOCTYPE hibernate-configuration PUBLIC
      "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
      "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
      <hibernate-configuration>
      <session-factory>
      oracle.jdbc.driver.OracleDriver
      password
      jdbc:oracle:thin:@sampr01.world
      jwestra
      SAM_DATA
      org.hibernate.dialect.Oracle9Dialect
      </session-factory>
      </hibernate-configuration>

      and then created the Hibernate Configuration for the perspective. Clicking on the Database icon produces the following error:

      Problem while reading database schema

      And the following warning:

      WARN Worker-33 org.hibernate.cfg.SettingsFactory - Could not obtain connection metadata

      Full stack trace of the exceptions that occur:

      !ENTRY org.hibernate.eclipse 2 30000 2006-11-17 16:19:15.459

      What other configuration information do I need. I believe that the warning is at the root of the problem, but I do not know how to remove it. What I do know is that the Oracle driver is not receiving properly the information it needs resulting its exception. What is missing?

      Any and all help would be appreciated

          Has anyone been able to solve this issue? I am running into the same problem. I am working with Oracle 10g, eclipse 3.2, and IDE 1.6

          When I try connecting to an Oracle database to do reverse engineeering I get the following error:

          Here is my hibernate.cfg.xml: 

          <?xml version="1.0" encoding="UTF-8"?>

 <property name="hibernate.default_schema">veria</property>

          Any help would be greatly appreciated.
