Hi!

I've beeen reading, browsing and searching the forum of all the posts concerning trouble with ANT and SchemaExport. It mostly comes down to CP-problems, and it seems that all posters make up their own, mostly home-made, solutions. I also see a lot of '?' about why it's working when they do things a particular way, and 'antipatterns' like putting some or another part of the CP that is required in the ANT_HOME is very common.

Now I've had a some hellish days with the SchemaExport task and ANT.
I won't describe all the error, missing classes and stuff I've seen, but it mostly comes down to either 'duplicate import'-errors OR 'class not found'.
I wish it could have been something in between. ;)

Well, my problem is clearly a CP issur, no doubt about that.
I have the following code structure:
C:/radius2/src, C:/radius2/bin, C:/onkcommons/src, C:/onkcommons/bin
The 'bin' directories hold the *.class and *.hbm.xml-files.

Now 'radius2' use some of 'onkcommons' classes. Nothing fancy, some interfaces etc.

I've really made an effort including the relevant classes in my ant task.
Classpath declaration:
Code:
<path id="schexp">
      <fileset refid="app.classes"/>
      <fileset refid="app.hbm.mapping"/>
      <fileset refid="project.commons.classpath"/>   
      <pathelement location="${src.home}/radius2/conf/log4j.properties"/>
      <pathelement location="C:/jdk/spring-framework-1.1.4/lib/log4j/log4j-1.2.9.jar"/>
      <pathelement location="C:/jdk/spring-framework-1.1.4/lib/jakarta-commons/commons-logging.jar"/>
      <path refid="hibernate.classpath"/>
      <path refid="driver.classpath"/>
   </path>


which all expands to:

Code:

My schemaexport target:

Code:
<target name="schemaexport" description="Generates a database initialisation file from *.hbm.xml-files">
      <taskdef name="schemaexport"
         classname="net.sf.hibernate.tool.hbm2ddl.SchemaExportTask"
         classpathref="schexp"/>
      <schemaexport
         properties="${hibernate.cfgfile}"
         quiet="yes"
         text="yes"
         drop="no"
         delimiter=";"
         output="${misc}\${app.name}_schema.sql">
         <fileset refid="app.hbm.mapping"/>
      </schemaexport>
   </target>



Additional:
Code:
<fileset id="app.hbm.mapping" dir="${appbin}">
      <include name="**/*.hbm.xml" />
      <exclude name="**/*.class"/>
   </fileset>


My hibernate.config file:

Code:
hibernate.connection.driver_class=com.mysql.jdbc.Driver
hibernate.connection.url=jdbc:mysql://localhost/radtest
hibernate.connection.username=
hibernate.connection.password=
hibernate.connection.pool_size=10
hibernate.statement_cache.size=25
hibernate.dialect=net.sf.hibernate.dialect.MySQLDialect
hibernate.cglib.use_reflection_optimizer=true



What more does ANT and the SchemaExport task need???
I feel that the schemaexport is a great tool, but judging from the many(!) and different ad-hoq solutions that people come up with, it is not only I that feel totally clueless in front of the same tool.
Any help or suggestions will be greatly appreciated!

Well, we don't really provide support for Ant or J2SE here. Ant classpath problems are just not specific to Hibernate and we are not enough experts in Ant to resolve such issues in the forum.

Thanks for your point of view and taking the time to write, but I posted in the "Tools" section of the Hibernate forum, and as I (perhaps wrong) assume that "SchemaExport task" is (at least) loosely connected to Hibernate.

A forum is a place to share experience and tips and tricks, and I was perhaps hoping for that more than regular "support", which I realize you cannot give.

Thanks again.

Hi again!

To add to the '?'-solutions of this problem:

As I changed all the <fileset>-tags in the task CP to <pathelement path=".."> it works inside Eclipse at least.
You will also have to add the log4j.jar to the Eclipse-ANT_HOME through "Settings..->ANT"

Comand-line doesn't work still.

Code:
<path id="schexp">
      <!--fileset refid="app.classes"/>
      <fileset refid="app.hbm.mapping"/-->
      <pathelement path="${src.home}/radius2/bin" />
      <pathelement path="${src.home}/onkcommons/bin" />
      <!--fileset refid="project.commons.classpath"/-->
      <pathelement location="${src.home}/radius2/conf/log4j.properties"/>
      <pathelement location="C:/jdk/spring-framework-1.1.4/lib/log4j/log4j-1.2.9.jar"/>
      <pathelement location="C:/jdk/spring-framework-1.1.4/lib/jakarta-commons/commons-logging.jar"/>
      <path refid="hibernate.classpath"/>
      <path refid="driver.classpath"/>
   </path>


ANT works in mysterious ways...
