I've been trying to run the schemaexport task for Listing 2.9 of Java Persistence with Hibernate on P65.
I'm struggling to understand why this class is not found.
If I'm reading the Ant script correctly, the taskdef for hibernatetool has a classpathref of project.classpath. This includes all the jars in my lib folder.
Which includes dom4j-1.6.1.jar.
This jar does have the class org/dom4j/io/OutputFormat!
So why is it not found?
Here is the build.xml:
Code:
<project name="HelloWorld" default="compile" basedir=".">
<!-- Name of project and version -->
<property name="proj.name" value="HelloWorld" />
<property name="proj.version" value="1.0"/>
<!-- Global properties for this build -->
<property name="src.java.dir" value="src"/>
<property name="lib.dir" value="lib"/>
<property name="build.dir" value="bin"/>
<!-- Classpath declaration -->
<path id="project.classpath">
<fileset dir="${lib.dir}">
<include name="**/*.jar"/>
<include name="**/*.zip"/>
</fileset>
</path>
<!-- Useful shortcuts -->
<patternset id="meta.files">
<include name="**/*.xml"/>
<include name="**/*.properties"/>
</patternset>

</target>
<!-- Compile Java source -->

</target>

</target>

</target>

Here is directory output that shows all versions etc:

Here is log4j properties:
Code:
# Direct log messages to stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
# Root logger option
log4j.rootLogger=info, stdout
# Hibernate logging options (INFO only show startup messages)
log4j.logger.org.hibernate=info
# Log JDBC bind parameter runtime arguments
log4j.logger.org.hibernate.type=info
I did notice in etc folder message types (INFO) were always in lower case. Tried this change. And still have same problem..
