Hi,

Ok, I am writing this post in a new thread because I really think that this issue deserves some importance. To start with I must say the web-application is now working fine :) which means that the problem is solved … however the confusion in my mind is not! :(

Basically I have been reading on this DocType problem for more then a week now. I had two problems that all of a sudden came out. The first problem was that Hibernate was telling me that I had the incorrect DocType, and the second problem was that XDoclet no longer wanted to generate the hbm.xml files.

Over here I was informed both times that I needed to change my DocType in order to make my system work again. I changed the DocType that very same day, but it still gave me the same problem. I thus continued searching, and was actually taking in consideration to change all my configuration using Annotations.

Last Friday I noticed that XDoclet re-started to generate the hbm.xml files again! This was very weird for me since I had done no changes to my code! Just a week before, XDoclet was giving me the following error when I tried to compile the hbm.xml files



This error has now vanished without me actually doing anything to correct it! (The first mystery!). Today (5th October 2006) I waked and said to myself; “If XDoclet started to work on it’s own, then why doesn’t the DocType start to work as well”. Therefore I went to work (I had the DocType set to 3.0) compiled my code and deployed it on JBoss (4.0.3SP1). To my amazment .. it worked!!

Since only a week before, with the same DocType and same code it did not want to work, I decided to try going back to the 2.0 DocType! … and the application worked fine again! What I mean is that my application is working fine both with this DocType:



and also with the following DocType



However since I am using version 3.1 of Hibernate, I am using the second one now.

The problem I have is that this problem came out in an un-logical way, and it has been solved also in an un-logical way. For met this does not make sense. I believe in the saying “For every action there is an equal and opposite reaction”. I did no action to break it, or to solve it.

My question is … what happened?

How can an application be working fine on a live server, break up, and then start working fine again without me actually doing any changes to the code.

Please note that I am not doing this post as a sign of anger or anything like that … far from it… to say the truth I am just very cuirass. The problem has interested me from the very beginning and I took it as a challenge. However I can not leave it to rest until I know what happened. I have a question in my brain that I really would like to have answers for!

I could be not seeing something that for you is very obvious! Thanks for any comments given, if you need any additional information please just let me know ... i will be more then happy to give it.

Hi,

No one can understand how this has happened? Also, howcome now both the DocType (specifying the DTD to be used) is now working for both 3.0 and 2.0 if I am using only Hibernate 3.0!!?

Please can someone give me some answers?

Please,

neighter the hibernate experts know what actually happened?

my problem is solved, so i am not asking for answers, I am actually asking what happened to know how I can avoid having such situations in the future!!

Just something that passed in my mind; Could it be that a fire-wall installed on my computer was blocking any signal returned by sourceforge.net?

Thank You,
