Larry,
I think I found where the issue come from, but still no workaround.
I have two projects, one is a simple Java project which performs DBMS data
access (say p1), and another web module (say p2). Not all of my .jar files
are copied in the WEB-INF/lib of p2 (webmodule) project, but they are
actually referenced through "Java EE Module Dependencies", so that Eclipse
copies p1 and p2 projects' dependencies to the target module deployment
folder's WEB-INF/lib.
p1 project has Utility Module facet, so that whenever it changes a new jar
file is created and exported to p2's WEB-INF/lib. The problem is that
whenever I change a simple .jsp page (in p2), a new p1.jar is created in
WEB-INF/lib and this is the cause that Tomcat reloads the module.
There is also another issue which I believe happens because of another facet
set in my p1 project. I have eclipselink.jar as a dependency in my pure java
project (p1). There is also a JPA facet set in p1 project. Whenever I change
a jsp, not only p1.jar is modified, but also eclipselink.jar is re-copied in
WEB-INF/lib.
Isn't it a bug in WTP facet engine?
Thanks,
Mohsen.
