Java Development Tools

Sorry this may be in the wrong forum, did not know where to put it...

I have developed an application on eclipse and tomcat with xe database,
if i deploy it on tomcat am i breaking any of the licenses, i mean the xe is free under 4 gb if you not living in an obsure country and do not break any of the other license rules,
but what if you use the database in your website on a tomcat server, are there any consequences by doing this?

thanks for your help.
