Hello, sorry for my english and sorry for repeat subject but the others topics with this subject didn't resolve my problem.

My example es very easy, i have a Dynamic web project with a 3 files: persistence.xml, hibernate.revenge.xml and build.xml.

I want to generate entitys and dao's with jpa annotations from a data base (Oracle10g).

build.xml:


<project name="MyProject" default="hbm2java" basedir=".">
<path id="lib.class.path">
<fileset dir="C:\Alvaro\Software\OtherLib">
<include name="*.jar" />
</fileset>
<fileset dir="C:\Alvaro\Software\JAR's">
<include name="*.jar"/>
</fileset>
</path>

<target name="hbm2java">
<taskdef name="hibernatetool" classname="org.hibernate.tool.ant.HibernateToolTask" classpathref="lib.class.path" />

<hibernatetool destdir="src">
<!-- JPA configuration -->
<jpaconfiguration persistenceunit="PruebaAntPersistence" />
<!--<jdbcconfiguration packagename="" configurationfile="hibernate.cfg.xml" revengfile="../WebContent/WEB-INF/hibernate.reveng.xml" ></jdbcconfiguration> -->
<hbm2java destdir="" templatepath="/templates" jdk5="true" ejb3="true" />
<hbm2dao destdir="" jdk5="true" ejb3="true" />
<classpath>
<path location="${build.dir}/target/classes" />
</classpath>
</hibernatetool>
</target>
</project>


If i uncommented line "<jdbcconfiguration....." ( with hibernate.cfg.xml instead of persistence.xml) and commented <jpaconfiguration... runs right

persistence.xml:


<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/ ... ce_1_0.xsd">

<persistence-unit name="PruebaAntPersistence" >
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<properties>
<property name="hibernate.connection.driver_class" value="oracle.jdbc.driver.OracleDriver" />
<property name="hibernate.connection.password" value="XXX" />
<property name="hibernate.connection.url" value="jdbc:oracle:thin:@XX.XX.XX.XX:XXXX:orcl28" />
<property name="hibernate.connection.username" value="XXX" />
<property name="hibernate.default_schema" value="XXX" />
<property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />
</properties>
</persistence-unit>
</persistence>


I put the file persistence.xml in all sites (/, /src, /src/META-INF, ........) of my project, and it is in Project\build\classes\META-INF

I don't understand why doesn't it run.

Thanks and sorry for my english again.

Remove line provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>

Thanks for replay Dmitry.

I have remove that line, but the problem persist.

I don't know why, but it don't find the persistence.xml file.

Thanks.

Probably you also need to change <path location="${build.dir}/target/classes" /> to <path location="${build.dir}/classes" />. Look where your Web-Inf folder is located.

I meant META-INF

Ok, i try it.

Thanks.

The problem continues

The stacktrace is:

Thanks.

Are you sure your META-INF folder in your <path location="<your path>" /> and has right persistent.xml? I asked because this shoud work(removed <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider> ?).

I'm not sure, but I put the absolute path:

<path location="C:\eclipse\workspace\PruebaAnt\build\classes\META-INF" />

If i go with windows explorer to this path, there is persistence.xml.

I don't know if that is right.

The line "<provider>....." is removed.

Can i use the file reveng.xml (or hibernate.reveng.xml) to configure generator code with jpa configuration???

I said you to put path to parent folder of META-INF. So your path shoud be
<path location="C:\eclipse\workspace\PruebaAnt\build\classes" />

Dmitry, thanks, already I had given up myself.

Thank you very much.

It run right!!!!!!!!!

Ok, it run right.

Buildfile: C:\eclipse\workspace\PruebaAnt\src\build.xml
hbm2java:
[hibernatetool] Executing Hibernate Tool with a JPA Configuration
[hibernatetool] 1. task: hbm2java (Generates a set of .java files)
[hibernatetool] log4j:WARN No appenders could be found for logger (org.hibernate.cfg.annotations.Version).
[hibernatetool] log4j:WARN Please initialize the log4j system properly.
[hibernatetool] 2. task: hbm2dao (Generates a set of DAOs)
BUILD SUCCESSFUL
Total time: 969 milliseconds

But i don't find generated code...

In my ant:


<hibernatetool destdir="src" taskname="hibernatetool">
<jpaconfiguration persistenceunit="PruebaAntPersistence" />
<!--<jdbcconfiguration packagename="" configurationfile="hibernate.cfg.xml" revengfile="../WebContent/WEB-INF/hibernate.reveng.xml" ></jdbcconfiguration>-->
<hbm2java destdir="src" jdk5="true" ejb3="true" />
<hbm2dao destdir="" jdk5="true" ejb3="true" />
<classpath>
<!-- <path location="${build.dir}" />-->
<path location="C:\eclipse\workspace\PruebaAnt\build\classes\" />
</classpath>
</hibernatetool>

But there isn't code in src folder...

Sorry for the new problem...

Yes, I faced the same problem... and the solution is: use jbdcconfiguration for this(because jpaconfiguration is not for reverceengeneering :( ). See http://docs.jboss.org/tools/3.0.0.GA/en ... l/ant.html.

Thank you very much Dmitry.

I will use jdbcconfiguration.
