StringIndexOutOfBoundsException while configuring Hibernate

Hi!

I'm trying to create a simple Usermanagment backend. Therefore I have some many-to-many relationships and a one-to-one.

Now when I try

Configuration cfg = (new Configuration()).configure();

I get a StringIndexOutOfBoundsException.
The last thing hibernate "said" before was:

net.sf.hibernate.cfg.Configuration - processing one-to-many association mappings

I'm a little bit confused, cause I have no one-to-many relationships defined.

Someone any ideas?

Thanks, Rico.

Set Hibernate logging to debug and post the output. That will tell you on which mapping file it is choking.

This type of setting in your log4j file will provide very verbose logging:

Code:

### direct log messages to stdout ### 
log4j.appender.stdout=org.apache.log4j.ConsoleAppender 
log4j.appender.stdout.Target=System.out 
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout 
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n 
 
### direct messages to file hibernate.log ### 
log4j.appender.file=org.apache.log4j.FileAppender 
log4j.appender.file.File=hibernate.log 
log4j.appender.file.layout=org.apache.log4j.PatternLayout 
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n 
 
### set log levels - for more verbose logging change 'info' to 'debug' ## 
 
log4j.rootLogger=warn, file 
 
log4j.logger.net.sf.hibernate=debug
 
### enable the following line if you want to track down connection ### 
### leakages when using DriverManagerConnectionProvider ### 
#log4j.logger.net.sf.hibernate.connection.DriverManagerConnectionProvider=trace 
 
### log JDBC bind parameters ### 
log4j.logger.net.sf.hibernate.type=debug
 
### log prepared statement cache activity ### 
log4j.logger.net.sf.hibernate.ps.PreparedStatementCache=debug
