Hi,
Currently I'm using MyEclipse but I want to switch to WTP (since it is
free and development progress seems stronger to me).
But I'm facing one huge downside of WTP compared to MyEclipse:
It seems that MyEclipse is using hot code replacement, since WTP drops
the webapplication classloader at all.
Here is the situation:
I start Tomcat (inside MyEclipse-IDE) and use the web-application. Then
I go back to the IDE and change the body of a method. Now MyEclipse does
a hot code replacement, what means that I can just refresh the webpage.
The running JVM has NOT forgot all its states, statics and sessions.
But with pure Eclipse and WTP after the change of the method a
"Reloading this Context has started" happens, what means that all
states, statics, sessios were dropped, what furthermore means that I've
to login again and go through the whole application again.
Is it possible to use hot code replacement also in WTP?
Regards,
Oli

Hi again,
finally it came up that my problem was only the "Auto Reload" = enabled
switch on the tomcat configuration screen in WTP.
Since hot code replacement is always active, the only problem was that
after a code change the "auto reload" feature caused the tomcat to
reload the context and therefore to drop any variables.
However, I find that the common switch setting for auto reload should be
disabled.

i second that. it would be nice if there was an option in "Preferences"
to disable auto-reload by default.

Going out on a limb here, since i dont use WTP's native tomcat plugin,
dut sysdeo's, where hot-code replace is working good. In my other
projects it seems hot-code replacements only works while in debug mode,
which happens to be sysdeo's default, so maybe when you start tomcat
using 'Debug on server' hot-code replacement will work? Or maybe you
tried it already and i'm way off, in which case, sorry for the spam :)
