Hi,
By going through the code it seems possible to achieve this by modifying
ProcessBuilder.addProcessFromFile. Easiest check would be to see whether the XML contains
element called as "process". Since XML Parsing is internal to the individual
releases (4.0 uses XStream and 5.0 uses XMLReader), I am not sure whether we should form a
XML document from the reader to check if the process belongs to version 4.0 or
compliant.
Brute force check would be indexOf ("<process") >= 0 then it is 5.0 else
4.0 ;-). I am sure there would be better ways than this kind of check.
I do not mind taking this further. Due to lack of in depth knowledge about drools, I am
not able to decide what the approach should be for checking the version.
This would be a really good feature as it would mean that drools 5.0 is backward compliant
for rule flows J. And this adds lot of confidence to enterprises.
p.s. Since this was now moving towards dev, I have moved the thread to the dev mailing
list.
Thanks.

You are a star, that saves us a lot of work :) I'm wondering if we can work this into
the package reader and some how have it detect whether something is version 4 or 5 and
convert first if it's 4, fancy having a look and seeing if that's possible?

Hi,
I have attached a file for translating rule flows from 4.0 to 5.0. I have tested my flows
with the XSL and it works fine. However, the XSLT may not be quite slick or compact as I
have touched upon XSLT after a long time. I have covered all the nodes available (ruleSet,
start, end, join, split, milestone, action and subProcess).
There is one issue in the XSLT. I have not added the xmlns attribute to the process
element. Reason is that this attribute appears in child nodes too with empty string, even
though it is not mentioned for the child nodes. This attribute is needed in the
'process' node because the Eclipse editor for 5.0 ignores the process node if
there are more than 2 sub processes in that ruleflow. Am not sure why this is happening
but that has been my observation.
In case XSLT is not present as an attachment then let me know the location where it can be
uploaded.
Thanks.

No they are not compatible, 5.0 has a new ePDL XML language that is human writable. I
suggest that somone in the community starts looking into an XSLT to translate them.

Hi All,
I wanted to know if RuleFlows made using the Eclipse 4.0.7 RuleFlow Builder will work with
5.0.0. When, I try to upload a 4.0.7 ruleflow into Guvnor, I get a NullPointerException
and before that the following:
Cannot find the declaration of element
'org.drools.ruleflow.core.impl.RuleFlowProcessImpl'.
I checked the 5.0.0M1 jars for drools-core, and this class seems to have been removed from
there. Also, after installing the 5.0.0 plug-in into Eclipse, my rule-flow nodes have all
gone.
Also, this may be a minor bug but it says(both in the docs and the BRMS Guvnor M1
Release):
"Ruleflows allow flow control between rules. The eclipse plugin provides a graphical
editor. Upload ruleflow .rf files for inclusion in this package.":
Should the .rf say .rfm ?

You are a star, that saves us a lot of work :) I'm wondering if we can work this into
the package reader and some how have it detect whether something is version 4 or 5 and
convert first if it's 4, fancy having a look and seeing if that's possible?

Hi,
I have attached a file for translating rule flows from 4.0 to 5.0. I have tested my flows
with the XSL and it works fine. However, the XSLT may not be quite slick or compact as I
have touched upon XSLT after a long time. I have covered all the nodes available (ruleSet,
start, end, join, split, milestone, action and subProcess).
There is one issue in the XSLT. I have not added the xmlns attribute to the process
element. Reason is that this attribute appears in child nodes too with empty string, even
though it is not mentioned for the child nodes. This attribute is needed in the
'process' node because the Eclipse editor for 5.0 ignores the process node if
there are more than 2 sub processes in that ruleflow. Am not sure why this is happening
but that has been my observation.
In case XSLT is not present as an attachment then let me know the location where it can be
uploaded.
Thanks.

No they are not compatible, 5.0 has a new ePDL XML language that is human writable. I
suggest that somone in the community starts looking into an XSLT to translate them.

Hi All,
I wanted to know if RuleFlows made using the Eclipse 4.0.7 RuleFlow Builder will work with
5.0.0. When, I try to upload a 4.0.7 ruleflow into Guvnor, I get a NullPointerException
and before that the following:
Cannot find the declaration of element
'org.drools.ruleflow.core.impl.RuleFlowProcessImpl'.
I checked the 5.0.0M1 jars for drools-core, and this class seems to have been removed from
there. Also, after installing the 5.0.0 plug-in into Eclipse, my rule-flow nodes have all
gone.
Also, this may be a minor bug but it says(both in the docs and the BRMS Guvnor M1
Release):
"Ruleflows allow flow control between rules. The eclipse plugin provides a graphical
editor. Upload ruleflow .rf files for inclusion in this package.":
Should the .rf say .rfm ?

Hi,
By going through the code it seems possible to achieve this by
modifying ProcessBuilder.addProcessFromFile. Easiest check would be to
see whether the XML contains element called as "process". Since XML
Parsing is internal to the individual releases (4.0 uses XStream and
5.0 uses XMLReader), I am not sure whether we should form a XML
document from the reader to check if the process belongs to version
4.0 or compliant.
Brute force check would be indexOf ("<process") >= 0 then it is 5.0
else 4.0 ;-). I am sure there would be better ways than this kind of
check.
I do not mind taking this further. Due to lack of in depth knowledge
about drools, I am not able to decide what the approach should be for
checking the version.
This would be a really good feature as it would mean that drools 5.0
is backward compliant for rule flows J. And this adds lot of
confidence to enterprises.
p.s. Since this was now moving towards dev, I have moved the thread to
the dev mailing list.
Thanks.

New subject: [rules-users] Compatibility of Rule Flows from 4.0.7 to 5.0.0
Hi,
Yes the patch detects which version and upgrades on the fly (Abrakadabra magic ;-)).
There is a system parameter ("drools.ruleflow.port"). The code checks for
version only when the system parameter is set to true. This was added so that there is no
overhead (CPU time) for users who are using rule flows in 5.0 only. Users using the old
rule flows in 5.0 and want upgrade must set this parameter to "true".
Main file to be checked for changes is
src/main/java/org/drools/compiler/ProcessBuilder.java. The other files are related to
cleanup (format as well as code) or test cases.
Modifying ProcessBuilder was easier / cleaner to control the upgrade of rule flows instead
of ProcessReader. If you feel otherwise then let me know and I will modify it.
If you feel more test cases should be added to make this more sturdy then let me know
which ones and I can submit the same too.
Thanks.

New subject: [rules-users] Compatibility of Rule Flows from 4.0.7 to 5.0.0

Hi,
Yes the patch detects which version and upgrades on the fly
(Abrakadabra magic ;-)).
oh right, cool I'll check this out. I've been on conference for the last
3 weeks, so I've got behind on looking at JIRAs, so if it's magic then I
should be able to just include it.
There is a system parameter ("drools.ruleflow.port"). The code checks
for version only when the system parameter is set to true. This was
added so that there is no overhead (CPU time) for users who are using
rule flows in 5.0 only. Users using the old rule flows in 5.0 and want
upgrade must set this parameter to "true".
Main file to be checked for changes is
src/main/java/org/drools/compiler/ProcessBuilder.java. The other files
are related to cleanup (format as well as code) or test cases.
Modifying ProcessBuilder was easier / cleaner to control the upgrade
of rule flows instead of ProcessReader. If you feel otherwise then let
me know and I will modify it.
If you feel more test cases should be added to make this more sturdy
then let me know which ones and I can submit the same too.
Don't know how many test cases you have, but more is always good,
especially on something with so many different possabilities. Especially
for handling bad XML gracefully.
Thanks.

The code handles the migration right, does it already hook into the

saying the patch will detect which version of the XML it is, and
upgrade on the fly?
My assumption was that it was just some code to migrate from 4 to 5,
but someone still needs to execute that, so it seemed the easiest
route was to do this via an eclipse option for now - as hooking into
packagebuilder with auto detection was more work and needed more
testing, but if you have done this already....
In case there is a change of mind later on we already have a patch for
it ;-).

Hi,
By going through the code it seems possible to achieve this by
modifying ProcessBuilder.addProcessFromFile. Easiest check would be to
see whether the XML contains element called as "process". Since XML
Parsing is internal to the individual releases (4.0 uses XStream and
5.0 uses XMLReader), I am not sure whether we should form a XML
document from the reader to check if the process belongs to version
4.0 or compliant.
Brute force check would be indexOf ("<process") >= 0 then it is 5.0
else 4.0 ;-). I am sure there would be better ways than this kind of
check.
I do not mind taking this further. Due to lack of in depth knowledge
about drools, I am not able to decide what the approach should be for
checking the version.
This would be a really good feature as it would mean that drools 5.0
is backward compliant for rule flows J. And this adds lot of
confidence to enterprises.
p.s. Since this was now moving towards dev, I have moved the thread to
the dev mailing list.
Thanks.

There is one issue in the XSLT. I have not added the xmlns attribute

I checked the 5.0.0M1 jars for drools-core, and this class seems to
have been removed from there. Also, after installing the 5.0.0 plug-in
into Eclipse, my rule-flow nodes have all gone.
Also, this may be a minor bug but it says(both in the docs and the
BRMS Guvnor M1 Release):
"/Ruleflows allow flow control between rules. The eclipse plugin
provides a graphical editor. Upload /*/_ruleflow .rf_/*/ files for
inclusion in this package./":
Should the .rf say .rfm ?

Also, this may be a minor bug but it says(both in the docs and the BRMS Guvnor M1
Release):
"Ruleflows allow flow control between rules. The eclipse plugin provides a graphical
editor. Upload ruleflow .rf files for inclusion in this package.":
Should the .rf say .rfm ?
Cheers,
Vikrant
