That, to me seems to be the problem, if Netbeans is not giving you the
choice of 1.6
it can only see JRE 1.5
Scripting is a new feature in JRE 1.6!
So you need to tell TC and NB to use the JRE 1.6
If TC running as a service if you double click on the feather in the task
bar, and go to the JAVA
tab, in the JVM setting you will see something like
C:\jdk1.5.0_06\jre\bin\server\jvm.dll
must be (find it on your machine)
C:\jdk1.6\jre\bin\server\jvm.dll
In NB, you go to TOOLS->PLATFORM MANAGER and show it where you have Java
JRE/JDK 1.6 installed
Then just make sure you existing project uses it at source level, ie it will
still give you the option of compiling it as 1.5, but thats no good it must
be 1.6.

As we understand it, your application is looking for a class that only comes
in 1.6
It can find that class because the Java engine you running is 1.5.
But as we understood it, it was working in the embedded TC that comes with
NB, so that implies that it was working on JRE 1.6
and that the new TC was not...
We THINK the problem is that you have things working on different JRE's on
your machine... they must all work on the the same 1.6 one, then your DEV
environment and various TC's will work together.

NO... create a convenient projects folder on your machine and NB will put
the files there.
When you compile, and run, NB creates a build folder, and then ASKS the TC
that you have SET, to run it.
So it actually runs in that new TC you installed.
When its all debugged... and I imagine now its taking you to a functions
that it cant find (because the class is in JRE6), then you stop NB from
running that Tomcat.... compile it and just drop the WAR into any TC the
USES JRE 1.6

NO, in the DEV environment you do nat have to deploy, just compile and run
it or debug it.
When you done you can deploy... but I prefer actually copying the WAR file
from the project to WEBAPPS, that what other people will do.
If you deploy it.... the TC wants to use the file now in TC webapps... but
while you testing you still want it to use the files in NB BUILD (your test
project) because you can debug that easily.
Get the JRE the same for everything....
You may be collecting JRE's automatically on windows... it does that....
What I always to is get the actual JDK for java, stick that in a special
folder, and tell the DEV environment to use it... then everytime browser JRE
prompt for updates, it doesnt matter if the user on the machine installs all
this stuff.
If you install the JDK1.6
Then install TC (on windows its setup)... point at that JDK6
Then install NB (on windows its setup)... point at that JDK6
Then just show NB where the new TC is.
You done!
Good luck ;)
