Hibernate version: 3.2.1GA

Hello,

I write a template for the generic exporter, with a single file output.

Inside i use the differents references from the configuration:

Code:

${cfg.getProperty("hibernate.connection.driver_class")}
${cfg.getProperty("hibernate.connection.url")}
${cfg.getProperty("hibernate.connection.username")}

this work well, but when i want to use the password:

Code:

${cfg.getProperty("hibernate.connection.password")}

there is the following exception:

org.hibernate.tool.hbm2x.ExporterException: Error while processing Configuration with template springBeans.ftl
freemarker.core.InvalidReferenceException: Expression cfg.getProperty("hibernate.connection.password") is undefined on line 36, column 42 in springBeans.ftl.

Yet, all these properties are in my hibernate.cfg.xml:

Code:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="hibernate.bytecode.use_reflection_optimizer">false</property>
        <property name="hibernate.connection.driver_class">org.hsqldb.jdbcDriver</property>
        <property name="hibernate.connection.url">jdbc:hsqldb:hsql://localhost/</property>
        <property name="hibernate.connection.username">sa</property>
        <property name="hibernate.connection.password">hello</property>
        <property name="hibernate.dialect">org.hibernate.dialect.HSQLDialect</property>
    </session-factory>
</hibernate-configuration>

Is there some security restriction or anything?

Thank you by advance.

It may not be any security issue..The best way to eliminate such option is hard code password value instead of using ${cfg.getProperty("hibernate.connection.password")} and see if things work fine. Also, System.out of such value should tell you if reading happening poperly or not..(may help in finding out any spelling issues etc)

Thanks you for your attention.
I think we are missunderstood.

I use eclipse hibernate tool 3.2.1GA

I'm coding a template (a .ftl file) which is used to generate a file. And i want this file to be printed with the password value of the hibernate configuration.

So i write ${cfg.getProperty("hibernate.connection.password")} in the template. (like i do with other value like username and so on.

I can't hardcode the password in the template, it will be used for many databases.

I would say the exception is launch at the file generation time, and it say "this property doesn't exist". Otherwise i know it exist because i wrote it in the hbm.xml

Thank you and Sorry for the bad english.

Yes, every prop work properly except the password.

sounds very weird then since I can't find any place in hibernate core or tools where this password should be stripped out.

very curious, so i decided to externalize these information from generation, but it don't solve the original problem.

Thank you

fyi, I just tested this with:

${cfg.getProperty('hibernate.connection.password')

and that worked perfectly.

${cfg.getProperty('hibernate.connection.somethingthatdoesnotexist')

failed like you see.

So I cannot reproduce it.
