Re: [wtp-dev] Eclipse 3.1 and J2SE 1.5 (1.4 compatibility mode) support

[David M Williams <david_williams@xxxxxxxxxx>]

Alexander, please open a feature request
in bugzilla (wst.xml) so we can track and prioritize your request with

everything else. 

I did notice the other day that we need
to update our DOM implementation to DOM Level 3 Core for J2SE 5 support,

and plan to add it to a milestone plan,
but have not assessed the actual effort required.

As a project, we need to (re) assess
our ability to support running on J2SE 5.
I am curious though, what is it about
Pollinate's code/function that requires this level of J2SE?

BTW, the use of enum as a variable name
seem very isolated and easily fixed, feel free to 
add a bugzilla (with patch?) for those
as well.

Subject	[wtp-dev] Eclipse 3.1 and J2SE 1.5 (1.4 compatability mode) support

To: wtp-dev

Hello,

For the last few weeks I've tried to integrate Pollinate project to run
against WPT.

I've succeeded partially: I was able to create simple Pollinate Web 
module against
WTP N20041101 build and actually run the sample Beehive application on
Tomcat
5.0.27. The reason why I tried N20041101 first is that I can't develop
against latest
build because of the recent bug: 
https://bugs.eclipse.org/bugs/show_bug.cgi?id=79302
but this is not my main concern here.

As you may know Pollinate target operating environment is Eclipse 3.1 
and J2SE 1.5.
And from WTP Project 1.0 Plan I know that your plan is to support mainly
1.4 for
the first 1.0 release.

My main question is can you improve your support up to J2SE 1.5 in 1.4
compatibility
mode?

The reason I'm asking is that there are some small library level 
incompatibilities between
Sun's 1.5 and 1.4 (e.g. in org.w3c.dom.Node interface). So as soon as 
you'll get latest
CVS trunk in 3.1 under 1.5, you will notice the problems. This problem
can be solved
if you'll support "library" level compatibility with 1.5. Most
of the 
core Java 1.5 features
are backward compatible.

Another way to solve this is to put correct version of XML under 1.5 
endorsed dir to
override the default one. But this is different story.

Another thing is: many of  WTP projects have their Java compiler 
settings to workspace
default. In my workspace it is 1.5, so many languages problems (e.g. 
using enum, which
is a reserved word in 1.5) can be avoided if project will explicitly set
the 1.4 compliance
level.

Thanks,
Alexander Smirnoff
Pollinate Project.
