Hi,

We are transforming all native JDBC based database transaction calls into Hibernate. The existing web application uses Alfresco based Content Management web tool. The version of Alfresco we are using itself uses Hibernate 3.2.1. For our custom backend java code we were told we cannot use any higher version of Hibernate. Is it true there could be conflict between Hibernate sessions where the Alfresco app is using the older version and our code using a higher version of Hibernate? We do not have problem using a higher version of Hibernate 3.5. But using the Hibernate 3.2.1 jars running into errors in running a simple test application. Here's part of the error I am getting -
Exception in thread "main" java.lang.NoSuchMethodError: org.objectweb.asm.ClassWriter.<init>(I)V
at net.sf.cglib.core.DebuggingClassWriter.<init>(DebuggingClassWriter.java:47)
at net.sf.cglib.core.DefaultGeneratorStrategy.getClassWriter(DefaultGeneratorStrategy.java:30)

This is list of jars I have -

asm-all-2.2.3.jar
asm-util-3.1.jar
cglib-asm.jar
asm-commons-3.1.jar
cglib-2.2.jar
antlr-2.7.6.jar
dom4j-1.6.1.jar
commons-collections-3.1.jar
commons-logging-1.1.1.jar
ejb3-persistence.jar
hibernate-3.2.1.jar
log4j.jar
ojdbc14.jar
slf4j-1.5.0.jar
slf4j-api-1.5.8.jar
slf4j-log4j12.jar
hibernate-annotations.jar
hibernate-commons-annotations.jar
javassist-3.9.0.GA.jar
jta-1.1.jar

Not sure if have any which could create conflict or may be redundant.

Thanks

I’ve never tried that error until this time actually. But later I am going to install some of those apps so I need to check this out. I might encounter this error on the two versions in web app.
