Lars, In your ant build script, I don't see where you are specifying against which database the reverse mapping tool should run. You need to provide your username and password as well.
In my setup, I have an initial database already up and running. In my build directory, I have a build.xml file and then a META-INF/persistence.xml file. When I run "ant reversemap" of my build.xml file, it generates an orm.xml file and all of my java source. You will have to update my files with your database info but here they are in case they might be of help. I did have to modify the orm.xml file a bit after it was created so it was exactly how I wanted, but it did work as-is without my changes. Here's my persistence.xml file (and below is my build.xml file): <?xml version="1.0"?> <persistence 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/persistence_1.0.xsd"; version="1.0"> <persistence-unit name="test" transaction-type="RESOURCE_LOCAL"> <provider> org.apache.openjpa.persistence.PersistenceProviderImpl </provider> </persistence-unit> </persistence> Here's my build.xml (I've cut out some pieces which aren't relevant). build.xml --------- <?xml version="1.0" encoding="UTF-8"?> <project default="reversemap" name="test" basedir="."> <property environment="env"/> <condition property="bea.home" value="${env.BEA_HOME}"> <isset property="env.BEA_HOME"/> </condition> <fail unless="env.BEA_HOME" message="The BEA_HOME property must be set"/> <condition property="package.name" value="${env.PACKAGE_NAME}"> <isset property="env.PACKAGE_NAME"/> </condition> <fail unless="env.PACKAGE_NAME" message="The PACKAGE_NAME property must be set"/> <property name="dbdriver" value="oracle.jdbc.OracleDriver"/> <property name="dburl" value="jdbc:oracle:[EMAIL PROTECTED]:1521:mysid"/> <property name="dbuser" value="myusername"/> <property name="dbpass" value="mypassword"/> <path id="classpath"> <pathelement path="${basedir}" /> <pathelement path="${basedir}/META-INF" /> <fileset dir="${bea.home}/modules"> <include name="javax.persistence_*.jar"/> <include name="org.apache.openjpa_*.jar"/> <include name="com.bea.core.apache.commons.lang_*.jar"/> <include name="javax.transaction_*.jar"/> <include name="javax.resource_*.jar"/> <include name="com.bea.core.serp_*.jar"/> </fileset> <fileset dir="${bea.home}/modules"> <include name="com.bea.oracle.ojdbc14_*.jar"/> </fileset> </path> <path id="classpath.oracle"> <fileset dir="${bea.home}/modules"> <include name="com.bea.oracle.ojdbc14_*.jar"/> </fileset> </path> <!-- =========================================== --> <!-- Runs against the database to create an orm.xml file and java classes --> <!-- =========================================== --> <target name="reversemap"> <!-- Removes any previously generated orm.xml --> <delete> <fileset dir="${basedir}"> <include name="orm.xml" /> </fileset> </delete> <taskdef name="reversemappingtool" classpathref="classpath" classname="org.apache.openjpa.jdbc.ant.ReverseMappingToolTask"/> <reversemappingtool package="${package.name}" directory="${basedir}/build"> <!-- This must be set to your database --> <config connectiondrivername="${dbdriver}" connectionurl="${dburl}" connectionusername="${dbuser}" connectionpassword="${dbpass}" propertiesfile="META-INF/persistence.xml"/> <classpath> <pathelement path="${classpath}"/> <pathelement path="${basedir}"/> <pathelement path="${basedir}/META-INF"/> <pathelement path="${classpath.oracle}/> </classpath> <codeformat tabSpaces="4" spaceBeforeParen="true" braceOnSameLine="false"/> </reversemappingtool> <!-- This copies the persistence.xml and orm.xml into the directory where the java classes were generated --> <mkdir dir="${basedir}/build"/> <copy todir="${basedir}/build/META-INF"> <fileset dir="${basedir}"> <include name="orm.xml"/> </fileset> <fileset dir="${basedir}/META-INF"> <include name="persistence.xml"/> </fileset> </copy> </target> </project> ____________________________________________________________________________________ Special deal for Yahoo! users & friends - No Cost.
