HI Max,

I am giving here the contents of my hibernate.reveng.xml file and full stack trace for errors. Another detailed information on errors I have to give via a Screen Shot, but I don't find any way to attach it here.

Please try to help me on below details

My Schema ECSTEST contains the tables having Composite Primary Key

Seems like the bug into the template.

What can be the solution of this Bug??

abhikesath,
did you use custom templates?
I ask because I have looked into id template and can't understand how the error at the line could happened.

No, I have not used any custom template

Can you give me your db schema?

I did not got your question.
Do you want to know my schema structure(Tables contained in that) ?

Yes, sql or ddl.

CREATE TABLE PROJECT_CONFIGURATION (
CONFIGURATION_ID INTEGER NOT NULL,
ORIGINAL_VALUE1 CHAR(100) NOT NULL,
ORIGINAL_VALUE2 CHAR(100),
PROJECT_ID INTEGER NOT NULL,
CURRENT_VALUE1 CHAR(100) NOT NULL,
CURRENT_VALUE2 CHAR(100)
)

ALTER TABLE PROJECT_CONFIGURATION ADD CONSTRAINT PROJECT_CONFIGURATION_PK PRIMARY KEY
(CONFIGURATION_ID,
PROJECT_ID);

ALTER TABLE PROJECT_CONFIGURATION ADD CONSTRAINT PROJECT_CONFIGURATION_CONFIGURATION_FK FOREIGN KEY
(CONFIGURATION_ID)
REFERENCES CONFIGURATION
(CONFIGURATION_ID);

ALTER TABLE PROJECT_CONFIGURATION ADD CONSTRAINT PROJECT_CO_PROJ_FK FOREIGN KEY
(PROJECT_ID)
REFERENCES PROJECT
(PROJECT_ID)
ON DELETE CASCADE;

Hibernate-tools generated the following code to me:
<class name="test.ProjectConfiguration" table="project_configuration" schema="ecstest">
<composite-id name="id" class="test.ProjectConfigurationId">
<key-property name="configurationId" type="int">
<column name="configuration_id" />
</key-property>
<key-property name="projectId" type="int">
<column name="project_id" />
</key-property>
</composite-id>
<many-to-one name="project" class="test.Project" update="false" insert="false" fetch="select">
<column name="project_id" not-null="true" />
</many-to-one>
...
</class>

Probably you are using some old version?

I am using "hibernate tools 3.2.4.ga". Can you please send me the jar file you are using.

Try to replace the jar
https://anonsvn.jboss.org/repos/jbossto ... -tools.jar
into your org.hibernate.eclipse plugin.

your schema does not list the tables that the error is about - i.e. what is T20100125183747Exception ?

The name of the Entity in db I guess.

I mean the name of the Table.
