[hibernate-dev] Problem setting the package name using Hibernate Tools.

Tuesday, 27 May 2008

Hi,

I am experiencing a problem with the package name declaration during pojo and mapping
generation with Hibernate Tools without using Ant.

hibernate.cfg.xml:

&lt;?xml version="1.0" encoding="UTF-8"?&gt;

&lt;!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate
Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"&gt;

&lt;hibernate-configuration&gt;

  &lt;session-factory name="session1"&gt;

    &lt;property
name="hibernate.dialect"&gt;org.hibernate.dialect.DerbyDialect&lt;/property&gt;

    &lt;property
name="hibernate.connection.driver_class"&gt;org.apache.derby.jdbc.ClientDriver&lt;/property&gt;

    &lt;property
name="hibernate.connection.url"&gt;jdbc:derby://localhost:1527/travel&lt;/property&gt;

    &lt;property
name="hibernate.connection.username"&gt;travel&lt;/property&gt;

    &lt;property
name="hibernate.connection.password"&gt;travel&lt;/property&gt;

  &lt;/session-factory&gt;

&lt;/hibernate-configuration&gt;

hibernate.reveng.xml:

&lt;?xml version="1.0" encoding="UTF-8"?&gt;

&lt;!DOCTYPE hibernate-reverse-engineering PUBLIC
"-//Hibernate/Hibernate Reverse Engineering DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd"&gt;

&lt;hibernate-reverse-engineering&gt;

  &lt;table-filter exclude="false" match-catalog=".*"
match-name="FLIGHT" match-schema=".*"/&gt;

  &lt;table-filter exclude="false" match-catalog=".*"
match-name="PERSON" match-schema=".*"/&gt;

  &lt;table-filter exclude="false" match-catalog=".*"
match-name="TRIP" match-schema=".*"/&gt;

  &lt;table-filter exclude="false" match-catalog=".*"
match-name="TRIPTYPE" match-schema=".*"/&gt;

&lt;/hibernate-reverse-engineering&gt;

Code that generates pojos and mapping files:

try {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
cfg = new JDBCMetaDataConfiguration();
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
OverrideRepository or = new OverrideRepository();
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
InputStream xmlInputStream = new FileInputStream(FileUtil.toFile(revengFile));
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
xmlHelper = new XMLHelper();
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
entityResolver = XMLHelper.DEFAULT_DTD_RESOLVER;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
List errors = new ArrayList();

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
SAXReader saxReader = xmlHelper.createSAXReader("XML InputStream", errors,
entityResolver);
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
org.dom4j.Document doc = saxReader.read(new InputSource(xmlInputStream));
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
Configuration c = cfg.configure(confFile);
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
cfg.setReverseEngineeringStrategy(or.getReverseEngineeringStrategy(new
DefaultReverseEngineeringStrategy()));
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
cfg.readFromJDBC();
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
} catch (Exception e) {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
Exceptions.printStackTrace(e);
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
}

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
// Generating POJOs
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
exporter.getProperties().setProperty("jdk", new
Boolean(helper.getJavaSyntax()).toString());
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
exporter.getProperties().setProperty("ejb3", new
Boolean(helper.getEjbAnnotation()).toString());
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
exporter.start();
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
} catch (IOException ex) {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
Exceptions.printStackTrace(ex);
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
}

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
// Generate Mappings
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
try {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
pkg = SourceGroups.getFolderForPackage(helper.getLocation(),
helper.getPackageName());&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
File outputDir = FileUtil.toFile(pkg);
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
HibernateMappingExporter exporter = new HibernateMappingExporter(cfg,
outputDir);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
exporter.start();
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
} catch (Exception e) {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
Exceptions.printStackTrace(ex);
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
}

in the code outputDir is 
C:\Documents and
Settings\gowri\MyDocuments\NetBeansProjects\WebApplication57\src\java\Travel.

But the generated pojo and mapping files don't contain package as Travel .

&lt;class name="Person" table="PERSON"

&nbsp;&nbsp;&nbsp; &lt;id&nbsp; name="personid"

&nbsp;&nbsp;&nbsp; 

class name should be Travel.Person. 

Wondering why tools is not setting the package right ?

Secondly, even though I have defined the HibernateReverseEngineeringStrategy, why tools is
generating pojos and mapping files for all the tables in the db ? (Note:I have listed only
selected tables in the hibernate.reveng.xml).
