simple questions

[Yuan Ye]

I am learning webshpere with J2EE. Got three simple questions, please help.

1. I have a CMP-EJB working in my project, how can I delete one EJB and also the data entry in the DB? I have tried to use:

  
    entity = entityHome.findByPrimaryKey(new EntityKey(id));
entity.remove();
      or entityHome.remove(entity); 

but neither works.

2. I have the CMP-EJB mapped to the cloudscape datebase. (Using the default cloudscape DB coming with WSAD) Everything is fine. But I don't know how can I look at the DB manually. Like in SQL server, it provides admin tool to look or change the entry in each table. But I can't find the tool in WSAD. I can see the DB structure, columns and keys. But how can I see the current entries in the table?

3. A question about the cloudscape DB. Is cloudscape a fully developed relational database, like SQL server? Why cloudscape is working on my machine but I can't see any admin tool? Is cloudscape closely related to DB2, both from IBM?

Thanks.
