Hi,

I'm using the MyEclipse tool to generate mapping documents from existing database objects, and ran into a problem. The tool took a column name of "c_LEED_desc" and mapped it to a property of "cLeedDesc". The generated getters and setters were named getCLeedDesc() and setCLeedDesc(), but Hibernate did not recognize them. I found that I could work around it by adding methods getcLeedDesc() and setcLeedDest(), but wondered if anybody else has had this problem.

Shouldn't Hibernate have recognized the getCLeedDesc() and setCLeedDesc() methods?

Hibernate version: 2.1.6

Mapping documents:
...
<property name="cLeedDesc" column="c_LEED_desc" type="java.lang.String" />
...


Code between sessionFactory.openSession() and session.close():

Name and version of the database you are using: MySQL 4.1

Look like either your project containing mapping files is not in reference or in classpath with with your tool's project.
Try doing like that ..and take care of one more thing..
either give your tool ..path of hibernate config file or mapping files individually..dont give them both..Generally these tools have various options like ...

- properties files
- config files
- mapping files..

Just choose one of both..

I don't think that's the problem. I should have clarified; when the getter getcLeedDesc() is not commented out, everything works fine. Note that getcLeedDesc() is not the correct name of the getter for the cLeedDesc property (as I understand it). There already exists a getCLeedDesc() getter that is not commented out, but Hibernate does not associate that method name with the cLeedDesc property.

I'm pretty sure I've ruled out all environmental issues; the code does work, but only when I add a getter and setter where the first character of the property name is lower case rather than upper case. I will note that this is the ONLY property (out of over 150 in about 10 mapping files) where I have had this problem.

Thanks!
