I was scraping internet for one xslt when I was converting drools 2 to jboss
rule 4, but couldn't find one,
so I rolled up sleeves and created one by myself, put up here in case anyone
need it too.
welcome comments.

How complete is it? Do you have any unit tests? If so we should

Hi Mark,
I have a simple app converting around 30 drl files with about 230 rules
using this xslt, I was able to run all those rules without any manually
modification after covertion which was my goal -:), lazy me. this xslt
should cover most cases.
it converts two major parts: functions to package, rule to rule, and as
well as some minor tags such as import. out of those "functions" part is a
little hard, but I managed do it though xslt.
since my rules are not very complex ones, I'm sure there are some case I
don't cover. so far I know two issues:
1, the attribute for rules is not covered since I don't local attribute
for individual rule, we use global vars,
2, need put xml schema into header.
should be more, and that's why I put up here so that people can give
comments and suggestion to make its coverage wider and more useful.
BTW, this is only for "XML-to-XML" format, not drl format.
one thing I was impressed by the Jboss Rule 4 is the backward compatibility.
we were coded against JSR94 interface, after upgrade from drools 2 to 4, I
only did a minor change on global variable. it works perfectly. good work
Mark.

Hi,
I did some tailoring, the attached zip files contains three parts:
1,One readme file showing the structure and how to run;
2,The compiled class jar RuleConverter.jar which will convert given file
to new one
3,The eclipse project jar ConvertProject for any one might be interested.
welcome comments.

welcome comments.
Could you update the wiki page with this information? You can
upload the
jar and cut and paste your instructions into the wiki page:
http://wiki.jboss.org/wiki/Wiki.jsp?page=Drools2Migration
Once you've done that I'll also do a small blog referencing that page.

heh, nice to have a happy customer. Drools 5.0 will have some api
changes, but the basic stuff should work with no changes - actually
JSR94 will now have any changes, so this won't impact you, although
ofcourse you'll miss out on all the new power we are adding :) We are
trying to have full backwards compatability with 4.0 DRL and 5.0 DRL

How complete is it? Do you have any unit tests? If so we
should add this as a contrib project for other users.

Hi,
I appended my instruction to
http://wiki.jboss.org/wiki/Wiki.jsp?page=Drools2Migration, also uploaded the
jar file, ready for comments now :).
Thanks.

Hi,
I did some tailoring, the attached zip files contains three parts:
1,One readme file showing the structure and how to run;
2,The compiled class jar RuleConverter.jar which will convert given file
to new one
3,The eclipse project jar ConvertProject for any one might
be interested.
welcome comments.
Could you update the wiki page with this information? You can upload the
jar and cut and paste your instructions into the wiki page:
http://wiki.jboss.org/wiki/Wiki.jsp?page=Drools2Migration
Once you've done that I'll also do a small blog referencing that page.

heh, nice to have a happy customer. Drools 5.0 will have some api changes,
but the basic stuff should work with no changes - actually JSR94 will now
have any changes, so this won't impact you, although ofcourse you'll miss
out on all the new power we are adding :) We are trying to have full
backwards compatability with 4.0 DRL and 5.0 DRL
