Hello,
I hope someone here can give me a hint. I've been banging my head
against a wall trying to get Hibernate tasks to see a log4j.properties
or log4j.xml file for days. I'm using Ant (of course) for the build.
I'm new to Hibernate, but have used Log4j before without difficulty.
Hibernate's manual says you need only put log4j.jar and a properties
file in the classpath, and everything will work. This has not been
my experience.
-----------------------------------------------------------------
The bit of Hibernate code I've focused on is hbm2java, which
generates Java source from hbm.xml templates. Following James
Elliott's nice intro book, the target is called <codegen>:
<target name="codegen" depends="prepare-configs"
description="Generate Java code from hbm.xml files.">
<taskdef name="hbm2java"
classname="net.sf.hibernate.tool.hbm2java.Hbm2JavaTask"
classpathref="classpath.project"/>
<hbm2java output="${dir.src}">
<classpath>
<pathelement path="${classpath.project}"/>
</classpath>
<fileset dir="${dir.src}">
<include name="**/*.hbm.xml"/>
</fileset>
</hbm2java>
</target>
This *does* generate the file expected, but it complains:
codegen:
[hbm2java] Processing 1 files.
[hbm2java] Building hibernate objects
[hbm2java] log4j:WARN No appenders could be found for logger
(net.sf.hibernate.util.DTDEntityResolver).
[hbm2java] log4j:WARN Please initialize the log4j system properly.
My attempts to get hbm2java to see a Log4j properties file:
1. Copied log4j.properties (from Hibernate's demo) throughout
the build directory ('*' marks dirs with properties file):
ap * <--[build.xml is here]
|-build *
| |-classes *
| |-org *
| |-apnp *
| |-nrd *
|-lib *
|-src *
| |-config *
| |-org *
| |-apnp *
| |-nrd *
2. Altered classpath.project to include many locations:
<path id="classpath.project">
<pathelement location="${dir.src}"/>
<pathelement location="${dir.build}"/>
<pathelement location="${dir.build.classes}"/>
<pathelement location="${dir.build.classes}/org/apnp/nrd"/>
<fileset dir="${dir.src}/config">
<include name="*.properties"/>
<include name="*.dtd"/>
<include name="*.xml"/>
</fileset>
<fileset dir="${dir.lib}">
<include name="*.jar"/>
<include name="*.bat"/>
</fileset>
<fileset dir="${tomcat.lib}">
<include name="servlet-api.jar"/>
</fileset>
</path>
3. Made hbm2java use this classpath both as source for taskdef
and for running (as shown above):
<taskdef name="hbm2java"
classname="net.sf.hibernate.tool.hbm2java.Hbm2JavaTask"
classpathref="classpath.project"/>
<hbm2java output="${dir.src}">
<classpath>
<pathelement path="${classpath.project}"/>
</classpath>
<fileset dir="${dir.src}">
<include name="**/*.hbm.xml"/>
</fileset>
</hbm2java>
4. Had codegen display 'classpath.project' between hbm2java
taskdef and running hbm2java:
<pathconvert targetos="windows" property="classpathProject"
refid="classpath.project"/>
<echo>classpathProject = ${classpathProject} </echo>
Which shows (adding line breaks):
[echo] classpathProject =

The log4j.properties file from Hibernate's distribution, is
simple ('warn' changed to 'debug'; comments and file appender
deleted):
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
log4j.rootLogger=debug, stdout
log4j.logger.net.sf.hibernate=debug
log4j.logger.net.sf.hibernate.type=info
log4j.logger.net.sf.hibernate.tool.hbm2ddl=debug
The log4j.xml file, is also simple (file appender deleted):
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration debug="true"
xmlns:log4j="http://jakarta.apache.org/log4j/";>
<!-- System.out appender. -->
<appender name="ConsoleAppender" class="org.apache.log4j.ConsoleAppender">
<param name="Target" value="System.out"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern"
value="%d{HH:mm:ss} [%5.5t] %-5p [%-20.30c{1}] %x - %m\n"/>
</layout>
</appender>
<!-- Root logger. Sends all debug-and-up messages to console. -->
<root>
<priority value="debug" />
<appender-ref ref="ConsoleAppender" />
</root>
</log4j:configuration>
I'd be very grateful for any ideas on what else to test, or
how else to look at the problem.
Oh yes, Ant: 1.6.1. JVM: j2sdk-1.4.2
Thanks again,
