When will JSR094 (Rule Engine API) be integrated into WLS?

Hello All,
Any idea which version of WLS will have JSR094 Rule Engine API?
Thanks and Best Regards

Hi,
Here are some Rule Engine products.

CC and Lightroom integration: when will LR finally get a 100% integration into the installer?

It still gets installed to a different folder (ignoring the base folder I set for CC) and the installer still says it's not installed after installing.
I had CS6 and standalone LR before CC, that might be the cause, but I am NOT going to reinstall everything to get back to where I am now.
I bet there's some registry entries that override the settings you set in the CC installer, but apparently no one ever cared about cleaning this up.
Because CC doesn't recognize the LR installation properly (even if I installed it using the CC installer) LR never gets updated, I always get a popup on starting LR.
PLEAAASE fix the installer and/or the LR package so everything is fully integrated. Thank you!

addendum: Installation always goes to C:\Program Files\Adobe\Lightroom ... instead of C:\Adobe\ where all the other CC apps go.

Business Rules Engines?

Hi,
I have experience with embedding "CLIPS" which is a C rules engine as a
Forte Service Object which was easily wrappered using standard Forte
wrapper strategy.
Also, we have a sales rep in ATL who used to work @ ILOG and therefore
competed with Nueron Data, and from various conversations with mutual Forte
/ Rules Engine customers I've learned it would be a complimentary integration.
They all have some C-callable API and so a Forte Service Object would be a
good client to the rules engine api due to our support for multi-threading
when API is thread safe and additional option of replicating for load-bal
when API isn't thread safe. The later concept is analogous to our use of
DBSession object for interface with DBMS client api's.
Be aware, the experiences I hear about with the mentioned rules engines is
that there are not always business analysts truly capable of using the
Rules development interfaces provided by the tools.
So maybe the use of Forte Conductor's dynamic Process automation
capabilities may also be a fit. If you want to discuss how, let me know.

Has anyone on this list integrated a COTS business rules engine,
or components, into a Forte application? Specific products
of interest would be those from Neuron Data, ILOG, USoft
or, possibly, Vision Software.
If so, comments? Type of application? War stories?

Custom Rules Engine

Is there a good pattern that I could follow to create my own rules engine. My requirement is that I have a lot of business rules, but since they are kind of static I don't see the need to use a rules engine. These rules don't change and I need high performance. I want to write my own custom rules engine. Are there any sample designs or code that is available anywhere or could someone suggest how I should go about creating my own rules engine which can be maintained easily and also allows some flexibility.
Thanks

Hi aaugusty,
My requirement is that I have a lot of business rules, but since they are kind of static I don't see the need to use a rules engine. These rules don't change and I need high performance.
The default thinking of Rules has been usage of XML. So that we separate the static data from logic. Although the rules are etched in stone, they are easily readable and editable.
I want to write my own custom rules engine.
Persoanally written/owned rules engine means maintenance cost is more. Performance will be more at the start. Might deteriorate during maintenance.
Are there any sample designs or code that is available anywhere
A search in google got me a lot of links. See if you find this useful
http://www.fawcette.com/javapro/2003_08/online/xml_yboglaev_08_01_03/
Looks like java has a Rule Engine API as a R&D work.
or could someone suggest how I should go about creating my own rules engine
The above answer holds good for this too.
which can be maintained easily and also allows some flexibility. "
I tried to do something like this using only java code. After finishing the voluminous work. I was given a lateral thinking of using a script engine!!!!! What I say could be non conventional, but its really a crisp work. You can have rules data coming from XML and java scriptlets doing all of the simple logics using those data. Processing of your data and script is done by a Script engine. The output may be in xml. There are Script Engines available for download. That satisfies your requirement of creating, maintaing and operating RULES. There need not be an engine at all. And not much java too. Easy to manitain and higly flexible. Because you are using only xml and scripts.
Good luck.

Report Engine API 4.0 (upgrade to 4.1)

Hi,
In the incoming days we will face the upgarde of our current SAP BI Platform (4.0 SP8) to next minor release (4.1). One of most challenging points is to ensure the proper behaviour of existing SDK customizations based on Report Engine API available at 4.0. I know that SAP is promoting use of Restful Web Services as a way to implement functionality previously delivered by JAVA API but my question is. Will current Report Engine API based developments work under in 4.1 release? In other words, has SAP planned an smooth transition from Report Engine API to restful Web Services scenario (compatibility scenario ) or code will have to be completely rewriten ?
Thanks,

Hi Alfons,
As per the current situations Report Engines SDKs are still the same in BI 4.1 likewise in BI 4.0 all patches. You can perform the below functionalities with BI 4.x Report Engines SDK :
- Export Webi Report to some other format.
- View a Webi Report.
- Partial drilling.
- Save prompts in Webi reports etc.(Most of the functionalities are deprecated like schedule with prompts etc.)
On the other hand with Webi Raylight REST SDKs you can leverage the workflow of legacy functional parity of BusinessObjects XI 3.1 Report Engines SDKs.
By seeing as a future, it looks like most of the new development & enhancement are happens in the Webi REST world. So planning to rewrite the code in terms of REST SDKs is beneficial.
As you are talking about the compatability, Report Engines Java SDKs are same upto BI 4.1 Patch 4 release. But it might be possible that in future Report Engines Java SDKs are totally deprecated. You can also refer the Object Model Digram of Report Engines SDKs which gives you list of deprecated interfaces, classes & methods.
Hope it helps.
Thanks,
Shailendra

WL Portal 7.0 Rule Engine

How do I customize the Rules using the Rule engine that comes with Weblogic Portal 7.0? I would like to use these Rules not for Personalization but drive my application flow.
Where is the grammer for the Rules, if I want to build by hand?
Any help would be appreciated.
Bob

Bob,
I haven't seen docs that define rule grammers etc. However, you can interact with
the rule engine using either adviselet api or the rule engine api. You can amuse
yourself at http://edocs.bea.com/wlp/docs70/javadoc/index.html for WLP 7.0 for
e.g. Look into the APIs for RuleParser, RulesManager, RulesAdviceletImpl etc.
I've done work on this at the adviselet level (the one that actually gives advice)
to use thrid party rule engines etc., but hasn't customized rule engine itself
in lines of for e.g., getting rules from other rule engines and importing them
to WLP rule engine.
Hope this helps,

When will Firefox increase their HTML5 support?

Like, since Firefox 11 the HTML5 support hasn't gone up a bit. Like it supports 345 points. As when even Opera and Safari bulldozed Firefox with a 376 and 385 pointer. Then Chrome FLATTENED Firefox, with a 437 points. And even Internet Explorer is chasing Firefox like a cat and a mouse, with 319 points and counting. Like WHEN, will Firefox actually put some more effort into building their HTML5 support?

There is always work going on on increasing our support of the HTML5 standard. For example, from Firefox 14.0.1 to Firefox 17 (still in development, the HTML5Test has gone from 345 to 383. The HTML5 standard is still evolving, and work is always being done. However, this isn't the best place to discuss this. [https://developer.mozilla.org/ https://developer.mozilla.org/] is the developer portal for Firefox and covers all the HTML5 work going on.

Error when invoking Rule Engine using Java API

Hi,
I have implemented a Java class which calls the Rule Engine to execute the rules. If I test by setting the value of the input inside a main method and get the output, it is working fine. The ruleset is also invoked and there is no problem. However, when I expose this java class as a web service and invoke the web service, I get the below error. I dont get the error if the .rules file is not present in the loaction mentioned. I get the error when the .rules file is present in the location. Not sure if this is an issue with the java call outs or loading the dictionary.

When will ID Include Integrated Kindle .mobi Export?

InDesign Mavens,
Can anyone shed any light regarding why Adobe has yet to include Kindle .mobi generation (export) as an integrated function in InDesign?
The release of InDesign CC further illuminates this problem...KDP's latest Kindle Plugin for Adobe InDesign (PERPETUAL BETA) v0.9.7.3 does not appear to support InDesign CC.
Really...by now...why is it necessary for Adobe to force InDesign users to rely on a third-party, perpetually BETA plugin for so many years in order to gain access to one of the largest (if not the largest) eBook marketplaces?
WHEN WILL ADOBE integrate Kindle .mobi generation into InDesign?
Do you want .mobi export integrated into InDesign? Please indicate your request in the comments below (hopefully someone from Adobe InDesign's Product Management group will get the message).

My apologies for the delayed response. Also, my apologies for the incorrect assumption about InCopy exporting to Word. I should have limited my response to things I have better knowledge of… but in my defense, I had just read this snippet in the InCopy manual and it seemed fairly clear, so I went with it:
Export InCopy documents
You can save all or part of an InCopy document in a different file format. In most cases, each component (for example, text frames and graphics) in an InCopy document is exported to a separate file. The exception is exporting an InCopy document to Adobe PDF, which copies all of the text and graphics in a document to a single PDF file.
Do one of the following:
       To export text, click in the text with the Type tool .
       To export a graphic, click the graphic with the Position tool .
Choose File > Export.
Specify a name and location for the exported content, and then select a format under Save As Type.
The XML format appears in the list only if XML tags have been added to the document. If you are exporting text and don’t see a listing for your word-processing application, you might need to export the text in a format that the application can import, such as Rich Text Format. If your word-processing application doesn’t support any of the InCopy export formats, use the Text Only (ASCII) format.
My assumption was, if InCopy allowed you to export to different file formats, and if it provided a listing of word processor programs, and it gave the option to export to RTF, then Word must be one of the options. Apparently I was wrong. That being said, the point I was making is still valid.
I am questioning the rationale behind Adobes decision to exclude support for the Amazon Kindle reader format. The reason stated here is, “Kindle uses a proprietary format that is not an open standard so why should Adobe spend the resources developing a solution to support it?” In response, I expressed doubt that this is the true reason because Adobe fails to take this position in other applications and I mistakenly provided an invalid example. So allow me to correct this mistake and reiterate that Adobe does not require that a technology or language be an “open standard” in order to incorporate support for the same.
These are examples of Adobe products supporting non-standard technologies (that I have personally verified from with the applications):
Acrobat Pro:      Export to Word and Excel
Certainly these formats are not open standards
Photoshop:        Save as PXR format
Pixar originally created this proprietary format for use with proprietary Pixar Imaging Computers used in medical imaging applications and, of course, animation. Later it was adopted for use in Pixar’s Renderman and Marionette 3D animation programs. I didn’t research other image formats, but my guess is the majority are proprietary and not open standards.
Fireworks:          Export to Lotus Domino Designer
Really? Is this what Adobe considers an open standard?
Dreamweaver: Create files of type: ASP + Java Script, ASP + VB Script, ASP.NET C#, ASP.NET VB
Obviously these are proprietary Microsoft technology solutions.
I think this demonstrates Adobe’s position on open standards fairly well, and as to the question of “Why” Adobe should support Kindle: for the same reason Adobe supports all the other, non-standard technologies. Because developers need it and Adobe is in the business of providing tools for developers. With regard to the characterization that Plane Wryter’s workflow is somehow “non-standard” is absolutely ridiculous. Yes, it might be true that the majority of Adobe’s ePub developers have no need for the Kindle tools. However, Plane Wryter and I (and every other independent developer and small ISV) cannot afford to limit our options and exclude potential clients based on (stupid) limitations imposed by our chosen development tools. We must remain flexible in order to survive. Adobe should recognize this and make an attempt to provide for our needs as well as the needs of their big enterprise customers.
Adobes position on this is a perfect example why I always look for tools created by smaller providers who have a vested interest in catering to the needs of the little guy. That’s why I chose tools from companies like Frame Technology Corp (creators of FrameMaker), eHelp/Blue Sky Software (creators of the RoboHelp product line) Aldus (providers of PageMaker, Freehand, and PhotoStyler), and Macromedia (creators of Flash, Shockwave, and Dreamweaver). I originally began to use these titles when they were competitors of Adobe, but they have since been acquired. It’s unfortunate that Adobe doesn’t see the value in continuing to provide small companies and individual developers with flexible tools. What other option does the little guy have except to look for alternatives from companies who still have an incentive to provide the tools we need?
In conclusion, I don’t buy the “not an Open Standard” excuse for excluding support for the Amazon formats. It’s an excuse of convenience and one that is not reflected by other Adobe products. The real reason Adobe isn’t providing development tools for Kindle is most likely tied to their Digital Editions reader application. I can see some Adobe Fat-Cat exec sitting at his desk on the 30th floor, with his feet up and chair leaned back, smoking a Gurkha (a very expensive cigar) of course, saying something like, “what kind of sense (puff) does it make (puff puff) to invest money and resources into (puff) a new ePub reader program, then (puuuufff) turn around and offer development tools (puff pu pu puff) for our competitors products? It doesn’t that’s what! Needles to say, we will NOT offer Kindle development tools (puff)”.
This sounds closer to the truth than that silly line about open standards. I don’t know about the rest of you guys, but I have a thing about being fed a line from a uber-mega-corp that’s acquired the vast majority of it’s product line through shrewd business practices. Do I honestly think they consider my needs as a developer? Naahh, not really. I’m going to follow Plane Wryter’s lead since Adobe leaves no other option.
One last word of caution to Plane Writer, I don’t like the way Steve Werner wished you luck with Vellum… (nothing personal Mr. Werner) but it almost sounded like “Good luck with Vellum, Adobe will be acquiring them real soon… “ Call me paranoid, but history speaks for itself, doesn’t it? If it’s a good product that’s competing with Adobe, then they will want it. (can you feel the walls closing in?)

Crystal Report Print Engine API calls from Powerbuilder

I am using Crystal Report XI R2 with Powerbuilder 9.0. I am using Crystal Report API calls using crpe32.dll to display my reports. When i run my reports from my development machine where Crystal Reports is installed the reports run properly, but when i deploy my application on a server where Crystal Reports is not installed the report gives me error "Report has not been opened" , Error 599.
The database logon info is properly set in the RPT file.
I want to know whether it is possible to run reports without installing Crystal Reports and how do you do it?

Somehow, you will have to install the CR runtime...
Probably the best way will be to create a deployment project using a utility such as InstallShield, Wise, MS Visual Installer, etc. Use the RDC merge modules and add the crpe32.dll to the deployment project, ensuring the crpe32.dll is installed into the ...\3.5\bin directory. The Correct msm files are here:
https://smpdl.sap-ag.de/~sapidp/012002523100009381702008E/crxir2sp4_rdc_mm.zip
BTW., using the print engine APIs... Not something recommended, nor supported. Last header files for the crpe APIs shipped in version 9...

How to use Hashtable in Rules Engine. And objects within objects in rules

This is something to do with the JBoss Rules Engine.
I have an object called 'Employee' containing variables name(string), age(int), sex(string), an object Skill and other fields not relevant.
Now the Skill object contains name and desc as variables.
And now i have another seperate object called Test containing two hashtable: inputHT and outputHT.
i have appropriate data in each of the objects and the hashtable:
Employee e = new Employee();
e.setName("Name");
e.setAge(18);
e.setSex("f");
e.getSkill().setSkill("Trainer");
Hashtable ht = new Hashtable();
ht.put("age", new Integer(e.getAge());
ht.put("sex", e.getSex());
Test t = new Test();
t.setInputHT(ht);
Since this is something to do with drools rules: I have the appropriate code even for that.
Like obtaining the rules defined(.drl files) in a stream, constructing the package builder, rulebase and the working memory.
I will now explain u my .drl files(ie the rules that i have defined) and the error that i am encountering
when I have the rule as the following there is no error:
rule "testRule1"
when
e:Employee(age >= 18, sex == "f")
then
System.out.println("The lady can marry");
end
In the above rule we can see that only two simple variables contained in the employee object is being accessed and there is no error encountered.
But when I try to access the object "skill" in the employee object, the rule throws me an error when i am constructing the packageBuilder:
rule "testRule2"
when
e:Employee(skill.name == "Trainer")
then
System.out.println("The skill is trainer");
end
The error thrown is : unexpected token 'skill' and many other dump errors and also error: expected token ')'
I tried changing the when clause as the following:
when
e:Employee(skill.getName() == "Trainer")
and also
when
e:Employee(skill.getName().equals("Trainer"))
All of them throws the same above error.
But at the same time if i access only object without its variables, it is working fine. Like:
rule "testRule2"
when
e:Employee(skill == "Trainer")
then
System.out.println("The skill is trainer");
end
The above rule works properly and does not throw any error. But it is not a valid rule. But syntactically it is correct. and does not throw any error during packageBuilder.
Similarly, the problem is with the Hashtable
The below code works fine, but rulewise it is not valid, but syntactically correct. and does not throw any error
rule "testHT1"
when
t:Test(inputHT == "f")
then
System.out.println("Print this");
end
But the following code throws error, telling unexpected token 'inputHT' :
rule "testHT1"
when
t:Test(inputHT.get("sex") == "f")
then
System.out.println("Lady");
end
I even changed the when clause, but did not get the appropriate result and it threw me error.
when
t:Test(((String)input.get("sex")) == "f")
and also many other variants but of no use.
It would be of great help if u or anyone else could reply to this with some solution
Thank you in advance
