hibernatetool + ant + log4j frustration (stupid)

i an using eclipse and i have an ant build file i'm using to reverse engineer a schema. i have the ant build set up as an External Tool in eclipse, with no additional configuration beyond the default. ultimately, the hibernatetool task successfully reverse engineers the schema i'm interested in (which indicates that i'm doing *something* right), but i can't for the life of me get hibernatetool to log output. no matter what i do, i always get this error:

Code:

Buildfile: C:\Documents and Settings\km623\Desktop\antreveng.xml
[hibernatetool] Executing Hibernate Tool with a JDBC Configuration (for reverse engineering)
[hibernatetool] 1. task: hbm2java (Generates a set of .java files)
[hibernatetool] log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
[hibernatetool] log4j:WARN Please initialize the log4j system properly.

it's driving me up a wall. i am just trying to use the standard "log4j.properties" file included with the hibernate tools distribution, and no matter where i put it, it gets ignored. i've searched the forums here pretty thoroughly (i think) and the solutions seems to be "put log4j.properties in the classpath", so i explicity specified a classpath for it in my build and it still doesn't work.

Code:

<project>
     <path id="hibernate-tools">
      <fileset dir="C:\Program Files\eclipse-SDK-3.1.1-win32\eclipse\plugins\org.hibernate.eclipse_3.1.0.beta2\lib\tools">
         <include name="*.jar" />
      </fileset>

      <fileset dir="C:\Program Files\eclipse-SDK-3.1.1-win32\eclipse\plugins\org.hibernate.eclipse_3.1.0.beta2\lib\hibernate">
         <include name="*.jar" />
      </fileset>
      
      <fileset dir="C:\Program Files\Java\Oracle 10g 10.2.0.1.0 JDBC">
         <include name="*.jar" />
      </fileset>
   </path>

   <path id="hibernate-log4j-config">
      <pathelement location="C:\Documents and Settings\km623\eclipse\workspace\testhibernate\src\log4j.properties"/>
   </path>

   <taskdef name="hibernatetool" classname="org.hibernate.tool.ant.HibernateToolTask">
      <classpath refid="hibernate-tools"/>
   </taskdef>

   <hibernatetool destdir="C:\Documents and Settings\km623\Desktop\testantreveng\">
      <classpath refid="hibernate-log4j-config"/>
      <jdbcconfiguration configurationfile="C:\Documents and Settings\km623\eclipse\workspace\testhibernate\src\hibernate.cfg.xml"/>
      <hbm2java ejb3="true" />
      <hbm2hbmxml/>
   </hibernatetool>
</project>

any suggestions? disclaimer: i am not an ant guru. plus, i'm sure i'm just doing something really dumb, which is even more frustrating, ha ha...

it should of course be in the classpath of the taskdef where the hibernateool is loaded from

If you have added jars to the ant runtime in eclipse>preferences, try removing them or restore to default.

altering the <path id> to the following results in a ZipException for me:

Code:

   <path id="hibernate-tools">
      <fileset dir="C:\Program Files\eclipse-SDK-3.1.1-win32\eclipse\plugins\org.hibernate.eclipse_3.1.0.beta2\lib\tools">
         <include name="*.jar" />
      </fileset>

      <fileset dir="C:\Program Files\eclipse-SDK-3.1.1-win32\eclipse\plugins\org.hibernate.eclipse_3.1.0.beta2\lib\hibernate">
         <include name="*.jar" />
      </fileset>
      
      <fileset dir="C:\Program Files\Java\Oracle 10g 10.2.0.1.0 JDBC">
         <include name="*.jar" />
      </fileset>

      <pathelement location="C:\Documents and Settings\km623\eclipse\workspace\testhibernate\src\log4j.properties"/>
   </path>

alternatively, altering the hibernatetool taskdef in this manner *also* results in a ZipException:

Code:

   <taskdef name="hibernatetool" classname="org.hibernate.tool.ant.HibernateToolTask">
      <classpath refid="hibernate-tools"/>
      <classpath refid="hibernate-log4j-config"/>
   </taskdef>

in short, trying to add this file to the classpath explicitly for the taskdef is resulting in a ZipException.

the Eclipse External Tools classpath is set to the default; i.e., the default Ant Home and Additional Tasks & Support.

a classpath consists of *directories* or jars/zips - not single files.

which i believe i have specified as the "hibernate-tools" classpath. please correct me on this if i'm wrong.

for example, i have put the default log4j.properties file into "C:\Program Files\eclipse-SDK-3.1.1-win32\eclipse\plugins\org.hibernate.eclipse_3.1.0.beta2\lib\tools" and that is not working. is that not the classpath of the taskdef? the taskdef is working, as i am able to reverse engineer my schema, so i believe i must have specified the classpath properly and placed the log4j.properties file in that classpath. i don't know where i'm going wrong.

<pathelement location="C:\Documents and Settings\km623\eclipse\workspace\testhibernate\src\log4j.properties"/>

That is a *file* not a directory.

in other words

<pathelement location="C:\Documents and Settings\km623\eclipse\workspace\testhibernate\src\"/> would be much better.
