Please help me to debug the program
Thanks in advance BUBI

You are missing some jar(s) (cglib-xx.jar) which causes the given exception. You will find it in the "lib" dir of hibernate distro.

Hi Vijitha,

Thank you so much for your reply.It has now got no problem with the SessionFactory.But I found a strange error...

Hi Vijitha,

The strange errors ultimately removed...But it was replaced by another errors.

Let me first tell you the jar files I am using are...

mysql.jar
slf4j-api-1.5.2.jar
slf4j-jdk14-1.5.2.jar
hibernate3.jar
dom4j-1.6.1.jar
javassist-3.4.ga.jar
commons-collections-3.2.1.jar
jta-1.1.jar
antlr-2.7.6.jar
commons-logging-1.1.1.jar
cglib-2.2.jar.

Now the files are..

"Bubi dg", please check your private messages for an important administrative matter. Again.

[tabiul mahmood]

Make sure you have

asm.jar
asm-attrs.jar

By the way next time you hit "Class Not Found" exception, always check this website www.findjar.com

Hi tabiul mahmood,

Thanks for your wonderful support.I have finally managed to complete the project by adding asm-jar file.But its really difficult to add the the exact jar files according to the project requirements if one doesnot know the jar files.
