Hi,
Won't the servlet engine reload the servlet if we recompile the .java
classes? That is not to good for me for I do a bunch of initialization on
the first hit (compiling a xsl stylesheet in particular > 5 seconds; after
the first hit things are OK), and I would prefer that the session is not
lost.
We solved it by using Jython for all our modules. This gives the effect
that Jon wants - you can edit your source code and changes are reflected
immediately without a recompile. The downside is that Jython is a strange
beast at the best of times and we've had to create some workarounds....
I'm not an expert on this so feel free to tell me if I'm being stupid: Will
it make sense to create a custom class loader for modules? The custom
classloader can act in the following way:
1. On the first request it compiles a .java file (ant task or whatever else
makes sense)
2. On the next request it checks the .java file.
2.1 If it changed the class is recompiled and reloaded
2.2 If it did not change the current class is used
Any thoughts?
I'd be willing to give it a shot if you guys think it is feasible...
