Hi.
I am using SchemaExport tool, trying to load mapping files from a Jar file as well as
build path to drop my database tables. I get the following error when executing
drop.schema:
Buildfile: build.xml
init:
drop.schema:
[echo] Path: C:\FIREWALL_DEMO\build\com\bluecatnetworks\proteus\data\Rule.hbm.xml
[echo] Path: C:\FIREWALL_DEMO\lib\mappings.jar

[java] at
net.sf.hibernate.tool.hbm2ddl.SchemaExport.main(SchemaExport.java:282)
BUILD SUCCESSFUL
Total time: 2 seconds
My build target for drop.schema is:
<!-- Drop.schema target. Drop a database tables. -->
<target name="drop.schema" depends="init">
<pathconvert refid="hibernate.mapping.files" property="hibernate.mappings"
pathsep=" "/>
<pathconvert refid="jar.hibernate.mapping.files"
property="jar.hibernate.mappings" pathsep=" "/>
<echo message="Path: ${hibernate.mappings}" level="info"/>
<echo message="Path: ${jar.hibernate.mappings}" level="info"/>
<java classname="net.sf.hibernate.tool.hbm2ddl.SchemaExport" fork="true">
<arg line="${jar.hibernate.mappings} --drop"/>
<arg line="${hibernate.mappings} --drop"/>
<jvmarg value="-Dhibernate.dialect=${hibernate.dialect}"/>
<jvmarg
value="-Dhibernate.connection.driver_class=${hibernate.connection.driver_class}"/>
<jvmarg
value="-Dhibernate.connection.url=${hibernate.connection.url}"/>
<jvmarg
value="-Dhibernate.connection.username=${hibernate.connection.username}"/>
<jvmarg
value="-Dhibernate.connection.password=${hibernate.connection.password}"/>
<classpath refid="classpath.ref"/>
</java>
</target>
Everything is fine if I don't use a Jar file. All paths and mapping files are present
and correct inside the Jar file.
If anyone can help me with what the problem might be I would really appreciate it.
Rgds, Graeme.
