I am still working through the introductory tutorials for Cocoon 2.2,

According to my version, this is Task 8 (see below), but whatever
I do,
I get a resounding NO to both questions at the end.
NO -- RCL [UPDATE] in the console
NO -- change in the browser
Can someone please do one of the following:
confirm it doesn't work for them either OR
confirm that it works for them, 'out of the box' OR
explain exactly how to configure things so it does work.

Task 8. myBlock2{changing a spring-bean)
-------------------------------------------
In this task, we make some minor changes to a java file, and
observe the effect in
both the Maven console and in the Browser.
If the RCL `class reloader' is working, the changes should happen
without
stopping Jetty.
checklist
--------
* select myBlock2 in Eclipse
* mvn jetty:run
* see what happens in the console and the browser
* edit myBean.java
* see what happens when you save it
+ watch the output in the maven console
? Did you get a RCL [UPDATE] message ?
+ refresh http://localhost:8888/myBlock2/spring-bean
? did the browser show your edits ?
Once I saw it failing because the automatic compilation of Java
sources was turned off. Can you make sure that all classes are
compiled to ./target/classes?
Thanks for such an ultra-fast response.
my ./target/classes/ directory indeed contains no classes. it just
gets a chain of empty directories, as you would expect,
corresponding to my GroupId and artifactId.
Unfortunately i do not know how to 'make sure all classes are
compiled there', beacuse i have not
learned Java yet. Can you explain?
My working environment is usually Maven, Eclipse, and the 'Maven
integration for eclipse' plugin from
http://m2eclipse.sonatype.org/
But any sort of explanation would be VERY gratefully recieved.
When you run the Maven eclipse:eclipse goal, you should find a file
.classpath in the root directory of your module. Make sure that you
have an entry
<classpathentry kind="output" path="target/classes"/>
there.
After verifying this, go to the "Project" menu of Eclipse and make
sure that "Build Automatically" is checked.
Finally go to "Project - Clean ..." and rebuild your workspace
completely. Now class reloading should work.
HTH
I have now tried your suggestions several times but with no success.
a. NO -- .class files under ..target/classes/..../ when the
project is built.
b. NO -- RCL [UPDATE] in the console
c. NO -- change in the browser
What might i try next?

Sorry, I am getting the .class files under ../target/classes/..
they just are not visible in Eclipse, even after a 'refresh'
This morning I have narrowed the problem down a bit more.
First I built a block where there are no spaces in the path; it did not
help.
Then, in a different command window, I compiled an altered MyBean.java
by hand. RCL did pick this up
quite happily, and the altered output came to the Browser without
stopping Jetty.
++++++++ In detail +++++++++++
development directory: C:\LargeWhite\
groupid : whauphill.ken
artifactid: anotherBlock
Command Window One:
cd C:\LargeWhite\anotherblock
mvn jetty:run > jetty_run.txt
Command Window Two :
cd C:\LargeWhite\anotherBlock\src\main\java\whauphill\ken\anotherBlock\
( edit MyBean.java)
javac -d C:\LargeWhite\anotherBlock\target\classes\ MyBean.java
# and for luck
cd C:\LargeWhite\anotherBlock\target\classes\whauphill\ken\anotherBlock\
touch MyFalseBean.class
mv MyFalseBean.class MyFalseBean2.class
rm MyFalsebean2.class
+++++++++ result ++++++++++
At each stage the output to the browser was as expected.
the output to the main console was also as expected
(On this run, some was redirected to a file)
+++++++ The important bit, I think +++++++++
(when I compiled the new MyBean.java )
RCL [update]:
C:\LargeWhite\anotherBlock\.\target\classes\whauphill\ken\anotherBlock\MyBean.class
