Hi

I want to know what are all the jars needed by hibernate-tools.jar.

I am trying to implement the reverse engineering and added the following jars to the class path:

ant-1.6.5, antrl-2.76, asm, asm-attrs, cglib-2.1.3, commons-collections-2.1.1, commons-logging-1.0.4, dom4j-1.6.1, ehcache-1.2.3, hibernate-annotationsm hibernate-tools, hibernate3, jdbc2_0-stdext and jta jars

But I still get some class linkage problems during the compile time on the following which will result in NoClassDefFoundErrrors when I use the wizard to generate the pojos and hbms at runtime.

I am using Netbeans.

[verifyclasslinkage] Warning: net.sf.cglib.transform.hook.AbstractPreProcessor cannot access
org.codehaus.aspectwerkz.hook.ClassPreProcessor

[verifyclasslinkage] Warning: net.sf.cglib.transform.hook.AsmClassLoaderPreProcessor cannot
access org.codehaus.aspectwerkz.hook.ClassLoaderPreProcessor

[verifyclasslinkage] Warning: net.sf.cglib.transform.hook.AsmClassLoaderPreProcessor cannot
access org.codehaus.aspectwerkz.hook.ClassLoaderPatcher

[verifyclasslinkage] Warning: org.dom4j.datatype.DatatypeAttribute cannot access org.relaxng.datatype.DatatypeException

[verifyclasslinkage] Warning: org.dom4j.datatype.DatatypeAttribute cannot access com.sun.msv.datatype.DatabindableDatatype

And the exception is

java.lang.NoClassDefFoundError: org/dom4j/DocumentException

Please help me.

Thanks, G

I have no idea what netbeans is doing but the exception is common if you have multiple conflicting classloaders. Ask the ones that did the netbeans work...

Can you at least confirm about the jars. Do I need to add any other jars ?
Or the ones I have are enough ?

It all depends what you need.

the minimal set is hibernate3.2, dom4j, log4j, hibernate-tools.jar, cglib.

Eerything else is "add-on", e.g. annotations is only needed if you use annotations, ant only if you use ant, jdbc/jta/ehcace etc. only if you actually need to create a sessionfactory you need ehcache, jdbc etc.
