hmm...should not happen.

Does it happen on even the simplest project (just one simple mapped class)

maybe i don't know,but i think the problem is that database contains meny (appr 20) schemas and some of them contains more 100 tables, many relation joins and so on.

and when plugin tryed to create reverse enginnerind file, it tries to get all database children.

i think this is a problem, i'll try on another database, where are not so many database objects.

hi max, i got another error,
can you help me?

Error Description :

Code:

org.hibernate.console.HibernateConsoleRuntimeException: Received a NoClassDefFoundError, probably the console configuration classpath is incomplete or contains conflicting versions of the same class
  java.lang.NoClassDefFoundError: org.hibernate.cfg.reveng.OverrideRepository
    java.lang.NoClassDefFoundError: org.hibernate.cfg.reveng.OverrideRepository

here is screenshot :

or is there anywhere download link for eclipse and tools which surely work together without error.

maybe this error meant that versions are mismatch.

any idea?

yes, i tryed -clien option, but nothing better.

i have linux operation system and iu thougth that maybe this is a problem,
than i tryed to install eclipse on windows and then hibernate tools.

1. i think that number one problem is that Fetching Children from database, tools tryed appoximately half an hour to do this (when database is so large, many users,tabels relations), i thinks it would better if wizard gets only top level from database (for example shemas,catalogs ... ) and then on double click get concrete shema(catalog) objects, it would be faster.

2. and i found second problem while generate JBoss Seam Skeletons. Tool did not generate anything for seam.

#1 is because of you pointing to a large db. just don't use it if you can't point it to something smaller ;)

#2 seam templates is a different issue.

The only issue i'm concerned about is that you are getting class path/loader errrors - neither #1 or #2 is the cause of those.

#1. u're right max, when i point default shema, the problem resolved, if nothing pointed, tools tries to get all oracle database schemas and other objects.

#2. max can u tell me where i can post about this problem ?

when i tryed to generate hibernate code without seam, all works fine but when i cheked jboss sem skeleton app [beta] checkbox
this error occured. here is screenshot of teh error? is this jboss seam error ?
or maybe i need seem library into my project ?

that is an error that occurs because the seam templates does not handle composite keys.

if you are looking for seam generation of apps you should take a look at seam-gen which is part of seam.

HI,

You need to configure Hibernate console configuration also.
After adding Hibernate Plug-in to eclipse,
Press Ctr+N key.
Choose Hibernate Configuration File(cfg.xml)
While configuring database related stuff,
In the bottom, there is a checkbox.
Create a console configuration

Enable above option, then follow GUI, Console configuration is created.

Regds,
