AW: AW: AW: AW: [opencms-dev] OpenCMS6 backward module compatibility

... that's what lists are intended to be for...

Not sure whether you still have a question on the difference... If not,
forget the rest, if yes:

In OpenCms 6 (opposed to OpenCms 4! not 5), xmltemplates were used to create
a website. OC4 used frametemplates and stuff like this in a proprietary
(legacy) OpenCms 4 format. OpenCms 5 still supports these legacy formats,
but started to use JSP templates, which are "state of the art" in web
programming. OpenCms 6 will no longer support the OpenCms 4 legacy formats
(frame templates, etc.), where the CmsJspTemplate class belongs to, but
switch completely to JSP tempates and xml content definitions. This is
probably why the OpenCms guys (and girls?) moved this class and other
proprietary classes to the "legacy" folder and deprecated them.

OpenCms 5 and 6 supports JSP templates. Templates is still the right word,
as you use things like

<% if (cms.template("main")) { %> ... <% } %>

in your JSP files. Nevertheless, it has absolutely _nothing_ to do with the
"old" template mechanism, which used things like

<XMLTEMPLATE>
	...
</XMLTEMPLATE>

to build up a web site. This might be the reason why you were (are?)
confused.

Please bear in mind that I am not a OpenCms programmer, but "only" a user.
But my private website has been built on OpenCms 4, then OpenCms 5 and is
currently moved to OpenCms 6. This is because I like to experience new
"bleeding edge" things. When a web site is finished, it's starting to be
boring for me.

However, if you are a professional and have to migrate existing, live web
sites into OpenCms 6, you should severely consider to stick to OpenCms 5 as
long as there is no stable, released version of OpenCms 6 including proper
documentation. Especially the proper documentation is a MUST, but I can
understand that there is none with an Alpha version (although desireable).
Even with my small private site this takes me quite a while (I assume about
10 person days for ~30 web pages, as I also want to use the new xml content
mechanism and throw away my old, self written one for OpenCms 5).

Secondly, if you are a professional, I would use the time until a stable
OpenCms 6 version is released to learn more about Java, JSPs and tag
libraries. There are lots of good books on this on the market. This makes it
much much easier to use OpenCms.

Hope this helps...

Regards
Ulrich

Hi Ulrich,

I have 5 complete sites up un running using OpenCMS5,
I understand most of what is needed to create
templates, etc...My problem is the difference between
5 and 6, which is what brought me here with my
exception ;)

Thanks for answering anyway ;)
