Hello all,
I have read the following tutorial at
http://www-128.ibm.com/developerworks/opensource/library/os- ecl-jet/
and followed it step by step. Everything works as written under Eclipse 3.2,
EMF 2.2, JET 0.7.2, and EMFT JET 0.7.2
However, the same exact example does not work under my Eclipse 3.3M6, EMF
2.3, JET 0.8.0 and EMFT JET 0.7.2.
As a simple example, in eclipse 3.3, I create a new EMFT JET Transformation
Project.
The project comes with a very simple example - with the files "main.jet",
"dump.jet", "sample.xml".
To run it, I run "main.jet" as a JET Transformation with the Transformation
Input as "sample.xml".
This works fine in eclipse 3.2 and generates "dump.xml".
In my eclipse 3.3, it outputs the following in the console.
"Could not load JET template loader"
Under problems, it says "Referenced class
'org.eclipse.jet.compiled._jet_transformation' in attribute
'templateLoaderClass' is not on the plug-in classpath"
I searched the newsgroup and saw one post related to this problem but that
seemed to have been caused by something different than what I am
experiencing.
If anybody could offer any help I would greatly appreciate it.
Thank you.

Hi:
Not finding 'org.eclipse.jet.compiled._jet_transformation' (a Java class
generated by the JET compiler), suggests that there may be a problem with
the JET builder. Some things to do and check:
1) In the Package Explorer, click the little white triangle, and from the
menu that appears, click Filters. In the dialog, check "Java elements from
JET Transformation projects". This will reveal the Java source folder
(usually jet2java) into which the JET compiler writes generated Java
classes. Take a look, and see if any classes are there.
2) Select the project, and click Projects > Clean.... Ensure your JET
project is checked, and do the clean.. Then re-check the jet2java folder to
see whether anything has shown up. If you don't have automatic builds
enabled, you'll have to manually build the project by clicking Project >
Build Project.
3) If none of the above helps, take a look at the Error Log view. Look for
errors from the JET builder. If you find one, please submit a bugzilla, and
attach the stack trace from the error log. Here's a link for creating a new
JET bugzilla:
https://bugs.eclipse.org/bugs/enter_bug.cgi?product=M2T& version=unspecified&component=Jet&rep_platform=PC&am p;op_sys=Windows%20XP&priority=P3&bug_severity=norma l&bug_status=NEW&bug_file_loc=http%3A%2F%2F&shor t_desc=&comment=&commentprivacy=0&keywords=& dependson=&blocked=&maketemplate=Remember%20values%2 0as%20bookmarkable%20template&form_name=enter_bug&as signed_to=m2t.jet-inbox%40eclipse.org&qa_contact=
Thanks for giving JET a try,
Paul

Thanks for the reply.
I did check the two things you mentioned and the class files are not in the
folder jet2java when using eclipse 3.3.
Can you get JET working in your configuration of eclipse 3.3 or have you
only been using eclipse 3.2?
(Is JET confirmed to be working properly under eclipse 3.3?)
The error log shows multiple errors, one of them which is
"java.lang.IllegalArgumentException encountered while running JET Template
Builder."

I'm getting the same problem
Referenced class 'org.eclipse.jet.compiled._jet_transformation' in attribute 'templateLoaderClass' is not on the plug-in classpath
Any attempt to run a transform is met with the supremely unhelpful error message
'Could not load JET template loader'
The compiled java files are being generated and there are no errors in my Error Log.
I'm using Java 7 and Spring Tool Suite - any history of problems with either of those?
Any help you can give me would be incredibly helpful since I'm getting absolutely nothing from error messages etc.
