Hello folks

I am beginning to use hibernate. I bought the book "Java Persistence with Hibernate" and am going through the examples in chapter 2.

Now I am stuck trying to reverse-engeneer a table (MESSAGES) using an ant script. The important part of the ant script is this:

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

<target name="reveng.hbmxml" description="Produces XML mapping files in src directory">
<hibernatetool destdir="${basedir}/src">
<jdbcconfiguration propertyfile="${basedir}/helloworld.db.properties" revengfile="${basedir}/helloworld.reveng.xml" />
<hbm2hbmxml />
<hbm2cfgxml />
</hibernatetool>
</target>

When I run this, I get this exception:
java.lang.NoSuchMethodError: org.hibernate.mapping.SimpleValue.<init>(Lorg/hibernate/mapping/Table;)V

Unfortunately I can not supply to you the call stack of this exception because it is not displayed.

I browsed the internet and found out that this error might have to do with some incompatible libraries - I just have no clue, which libraries are incompatible.

I'm using hibernate 3.6.6 and these libraries:

antlr-2.7.6.jar
c3p0-0.9.1.jar
commons-collections-3.1.jar
dom4j-1.6.1.jar
hibernate-jpa-2.0-api-1.0.1.Final.jar
hibernate3.jar
javassist-3.12.0.GA.jar
jta-1.1.jar
log4j-1.2.15.jar
mysql-connector-java-5.1.12-bin.jar
slf4j-api-1.6.1.jar
slf4j-log4j12-1.6.1.jar

asm-3.3.1.jar
cglib-2.2.jar
commons-logging.jar
freemarker.jar
hibernate-tools.jar (the one downloaded by eclipse as plugin)
jdity-r938.jar

Can anybody help?

Many thanx

I found out that this problem does NOT occur when I use hibernate3 version 3.5.4. When I use version 3.6.4 or 3.6.6, it doesn't work.

Can anybody give me a hint about which versions of supplemental libs I should use to be able to reverse-engeneer existing tables with hibernate3 version 3.6.6?

I'm currently using these libs:

antlr-2.7.6.jar
asm-3.3.1.jar
c3p0-0.9.1.jar
cglib-2.2.jar
commons-collections-3.1.jar
commons-logging.jar
dom4j-1.6.1.jar
freemarker.jar
hibernate-jpa-2.0-api-1.0.1.Final.jar
hibernate-tools.jar
hibernate3.jar
javassist-3.12.0.GA.jar
jta-1.1.jar
jtidy-r938.jar
log4j-1.2.15.jar
mysql-connector-java-5.1.12-bin.jar
slf4j-api-1.6.1.jar
slf4j-log4j12-1.6.1.jar

Many thanx

hey..i am getting kind of the same error while going through the same book.
i am also on the second chapter and was trying to run that helloworld using annotations.
i am getting the below error:

[copy] Copying 2 files to Z:\java work\workspace\LearningJPA\bin
run:

i have changed the Configuration to AnnotationConfiguration while creating the instance of the SessionFactory. it seems this error is also because of incompatible libraries.

this is the list of libraries i am using:

asm-1.5.3.jar
asm-attrs.jar
cglib-2.1.3
commons-collections-3.2.1
commons-logging-1.0.4
hibernate3.jar
hibernate-tools.jar
log4j-1.2.8
ojdbc6.jar
hibernate-release-4.1.9.jar

i started getting this error after i am trying to switch to Annotations.

i am really stuck here. any help will be appreciated.
