Warning - it does make debugging more difficult. Some others: yguard - http://www.yworks.com/en/products_yguard_about.htm retroguard - http://www.retrologic.com/retroguard-main.html jax - http://www.alphaworks.ibm.com/tech/JAX dasho - http://www.preemptive.com/tools/ I am using yguard, there is an ant task available for it, so it is very practical. Before yguard I used retroguard (yguard is based on this one) and tested JAX. JAX _seemed_ the best, but it is/was not free (not sure of its status now, it was years ago). I did not try dasho (not free). attila
