Hi !

Yes. here is Domain.java
public class Domain
{
public Integer Id;
public Integer Status;
public String Domain;
public String Comment;
public Domain(Integer Id,Integer Status,String Domain,String Comment)
{
this.Id = Id;
this.Status = Status;
this.Domain = Domain;
this.Comment = Comment;
};
public void setId(Integer Id)
{
this.Id = Id;
}
public Integer getId()
{
return this.Id;
}
public void setStatus(Integer Status)
{
this.Status = Status;
}
public Integer getStatus()
{
return this.Status;
}
public void setDomain(String Domain)
{
this.Domain = Domain;
}
public String getDomain()
{
return this.Domain;
}
public void setComment(String Comment)
{
this.Comment = Comment;
}
public String getComment()
{
return this.Comment;
}
}

Ok. Here is code and a result :
import org.apache.ojb.broker.metadata.DescriptorRepository;
import org.apache.ojb.broker.metadata.MetadataManager;
public class test_copyOfGlobalRepository_two
{
public static void main(String args[])
{
try
{
System.out.print("loading...");
String className = "Domain";
ClassLoader cl = Thread.currentThread().getContextClassLoader();
Class domain = Class.forName(className, true, cl);
System.out.println("OK");
}
catch(Exception e)
{
System.out.println("Something wrong with loading class");
e.printStackTrace();
};
try
{
System.out.println("Manipulating with MetadataManager");
MetadataManager mm = MetadataManager.getInstance();
mm.setEnablePerThreadChanges(true);
DescriptorRepository dr = mm.copyOfGlobalRepository();
}
catch(Exception ex)
{
System.out.println("Something goes wrong...");
ex.printStackTrace();
}
}
}
Output:
loading...OK
Manipulating with MetadataManager
Something goes wrong...

As you see class is not in package and loading without problems. Can you
provide some simple working example with all configuration files so I could
run and compare results ? Maybe I have a config mistake? Any suggestions are
welcome.
