two very import question!
hi every one!
1.i use hibernate tools to a old system,when hibernate create java code and hbm files,the hibernate tools need all tables has a primary key(if not ,hibernate tools will tell me a primary key error!)
2.when i write a Console Configuration,the hibernate tools use all JDBC metadata to produce the java and hbm files,but i want not this,i only want part of JDBC metadata(not all JDBC metadata).can i choose the JDBC metadata i want to produce ?(myeclipse can do this)

thanks for you help!

see tools.hibernate.org for the updated version which allow you to create a reveng.xml via a wizard to allow you select relevant tables.

and yes, all mappings need you to map some <id> as otherwise we can not know how to distinguish objects.

read total all JDBC metadata cost too much time!hibernate tools 5 can do some filter?????

hi,i write a xml file to filter the useless jdbc metadata

Code:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-reverse-engineering PUBLIC "-//Hibernate/Hibernate Reverse Engineering DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd" >

<hibernate-reverse-engineering>
  <table-filter match-schema="430100" match-name="JBXX"/>
  <table-filter match-schema="430100" match-name="SZXH"/>
</hibernate-reverse-engineering>

but when i make hibernate artifact generation(i had setup the reverse engineering file),the screen lock,just like i had not setup the reverse engineering file at all!

sorry,i use hibernate tools first time!!i use myeclipse before!

did you click the setup button ?

you need to add a exclude filter at the bottom of the list to state you dont want everything from the db.

e.g.
<table-filter match-name=".*" exclude="true"/>

if i click setup buttom,the configure table fiters still lock!can you speed it up?

too slow!

thanks for you help!

you could set the default schema/catalog then it would only list those.

How big a database are you actually using ?

error under artifact generation

reason:
org.hibernate.exception.genericJDBCException:Problems getting meta data for primary keys

first ,i set reverse-engineering,the speed should not be so slow!!
second,after a long time,i get the error message

Code:

error under artifact generation

reason:
org.hibernate.exception.genericJDBCException:Problems getting meta data for primary keys

what the mean for this error code?

thanks a lot

please stop putting all those !!!!! its annoying to read!!!!!!

then set the default schema/catalog and add a table-filter that excludes everything - then it will not scan through anything besides what you have included.
