ANT hbm2ddl --> NoClassDefFoundError: org/apache/commons/

Hibernate: 3.3.1
Hibernate tools: 3.2.4
Eclipse : 3.4
ANT : 1.7

Hi all,
I have a similar problem like that already discussed here
http://forum.hibernate.org/viewtopic.ph ... highlight=

The main difference is that I'm running hbm2ddl from ANT.

Code:

<target name="hbm2ddl" >
    <hibernatetool destdir="${basedir}/generated">
    <classpath>
        <path location="${classes.dir}"/>           
             <fileset dir="${lib.dir}">
            <include name="**/*.jar"/>
         </fileset>              
     </classpath>               
        
          <configuration configurationfile="${classes.dir}/hibernate.cfg.xml">
     </configuration>
         
     <hbm2ddl export="false" outputfilename="sql.ddl"/>
    </hibernatetool>         
</target>

When I run that code the console outputs this:
hbm2ddl:
[echo] hbm to ddl starting...
[hibernatetool] Executing Hibernate Tool with a Standard Configuration
[hibernatetool] 1. task: hbm2ddl (Generates database schema)

BUILD FAILED
/home/rgambelli/workspace_3_4/StrutsHib/build/build.xml:31: java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory

Total time: 4 seconds

Inside the classpath element inside hibernatetool task, the variable lib.dir points out to many jars one of which is obviously commons-logging-1.0.4.jar

What could I try?
Thanks and best regards
Gamby

At last I've resolved going to eclipse ANT preferences ANT --> Runtime
and inside Global Entries I added a reference to commons-logging-1.0.4.jar

Perhaps documenting this strange issue should be a good thing...

With this solution I was able to execute:
- hbm2ddl
- hbm2java

But trying with task hbm2hbmxml it doesn't work again....now the error is:
java.lang.NoClassDefFoundError: org/w3c/tidy/Tidy

what is in your classpath of the taskdef ?

Remember that is where the classes for the task needs to be,
classpath inside <hibernatetools> is only for your resources; not the hibernate tool task.

Hi,

I have also tried to put commons-logging-1.0.4.jar inside classpath of taskdef but it didnt' work...

Code:

<path id="toolslib">
       <path location=".........../eclipse/plugins/org.hibernate.eclipse_3.2.4.CR1-R200812191611/lib/tools/hibernate-tools.jar"/>
      <path location="................/eclipse/plugins/org.hibernate.eclipse_3.2.4.CR1-R200812191611/lib/tools/freemarker.jar"/>
      <path location="............./hibernate-distribution-3.3.1.GA/hibernate3.jar"/>
      <path location="............./java_lib/mysql-connector-java-5.0.3-bin.jar"/>
    
      <path location="................/java_lib/dom4j-1.6.1.jar"/>   
      <path location="..................../java_lib/slf4j-1.5.2/slf4j-api-1.5.2.jar"/>
      <path location="................/java_lib/slf4j-1.5.2/slf4j-nop-1.5.2.jar"/>
[b]       <path location="................lib/commons-logging-.0.4.jar"/>[/b]
   </path>      

   <taskdef name="hibernatetool" 
            classname="org.hibernate.tool.ant.HibernateToolTask"
            classpathref="toolslib" />

Perhaps you haven't read from beginning this thread...

I said that, speaking about common-logging, and running hbm2ddl, task which doesn't need org/w3c/tidy/Tidy, I've tried to include common-logging in the classpath of taskdef but it didn't work...

hbm2hbmxml needs also org/w3c/tidy/Tidy....

sorry, missed that.

But I don't get this when I run it from the commandline...

are you running it only through eclipse or is it also failing on commandline for you ?

I'm running ANT inside Eclipse.

Hi, I'm new in Hibernate, and learn from Hibernate in Action. And also, I do not any more where to store hibernate-tools.jar and what to do, because whatever I do I get the same exception when I try to execute schemaexport.
So, what is the problem? Is it so "book" bug, just to spent a day-two, in resolving some technical problems or what? So does anyone have the same problem and get an explanation. If any, please share with me, until I explode :-))
Thanks...

Please show me which example in hibernate in action that fails to run ?
