Is there a way to deploy drool files in kieserver without using workbench ? I want to create DRL files using eclipse IDE and deploy/execute rule definitions via HTTP/REST on stand alone kieserver.
Using kie-server-spring-boot-starter-drools I was able to setup a service packaging rule definition as DRL and invoke through HTTP/Rest post call on kieserver

I am using liferay 6.2 & built a maven portlet and working fine, I want to use its tables to store data for another portlet so that I need its services in this portlet.
But we can't access it externally so i find a way something like: required-deployment-contexts=Portlet-Project1 inside liferay-plugin-package.properties, then found its works for Ant only.
I was also finding the xxx-portlet-service.jar but didn't able to, so that i could manually put it in other portlet's lib folder i.e inside tomcat-webapps-xxxportlet-WEB-INF.
Just want to find how to use xxxLocalService.util in other in maven portlet
The best approach you can implement is a plugin to manage all the interaction with the DB.
First of all you must create a Service with a maven project and include it into your pom.xml in each portlet that you need. Then you can invoke its methods whenever you want because each portlet will store the dependencies.
Create Service Plugin into jar file
Rebuild with mvn clean liferay:build-service
Custom your own methods to manage the iteraction with the DB (LocalServiceUtilImpl and rebuild).
Include this plugin into pom.xml portlets
Rebuild your portlet.
The JAR will be placed in your .m2 folder, then each time that you rebuild your Service Plugin will be updated.
If i understood your question correctly, You need to create service builder project using maven and then you can add as dependency in other project wherever you need access to use xxxLocalServicutil class.
You can follow below link to create maven service builder project.

As you mentioned in your question.
was also finding the xxx-portlet-service.jar but didn't able to, so
that i could manually put it in other portlet's lib folder
To answer this, manually putting .jar file in lib directory will not help when you are working with maven project
I am learning angular 2 currently and trying to hosted in springboot java application.
I created a separate project using angular cli , then I created spring starter project with web only.
Next I imported the angular cli project inside /src/main/resources/static directory.
when I opened the browser , I was not able to see the basic index.html.
Then I removed all the imported files and imported only the content of the directory , which is the resulting compiled ES5 java script after transpiling the type script files in directory, this time it worked.
My questions are:-
1) What is the best practice , to use the GUI under /src/main/statis or create /src/main/public or /src/main/webapp ?
2) Does spring understand only js and not ts ( java script and not type script)?
3) Do I need a maven plugin for typescript and if so how to tell maven bundle the compiled js with the spring war while excluding the rest directories and files
4) How to include the testing unit / e2e with maven build
I searched for step by step guide for ANgular 2 and spring boot but could not find one. It would be helpful to many if some guide like this exist.
Many thanks for your support guys.
1) What is the best practice , to use the GUI under /src/main/statis or create /src/main/public or /src/main/webapp ?
Since typescript compiles to JavaScript I strongly recommend using GULP. I have my source files under src/client and I build with gulp to add the files to src/main/public
I believe either public or webapp works and there's not a huge difference.
2) Does spring understand only js and not ts ( java script and not type script)?
The newer version of STS has support for typescript, but I prefer to use visual studio code when viewing typescript files as there is better support.
3) Do I need a maven plugin for typescript and if so how to tell maven bundle the compiled js with the spring war while excluding the rest directories and files
If you use gulp, the typescript is compiled to js and added to the src/main/public directory where your springboot app sees the files when running with maven.
4) How to include the testing unit / e2e with maven build
I searched for step by step guide for ANgular 2 and spring boot but could not find one. It would be helpful to many if some guide like this exist.

I recommend using an angular seed or starter, this seems like the most up to date one that I've found:
https://github.com/antonybudianto/angular2-starter
This uses gradle, but is spring boot and angular 2:
https://github.com/borysn/spring-boot-angular2
I shared a project on github that integrates Angular 2 With spring boot. Just need to follow the step on readme or check commit history. You can access here Angular 2 with spring boot
This is where I am at:
I am using Drools 6.2 and calling drools engine remotely via KIE Execution Server running on jboss.
I used workbench to create my initial drl file and fact objects and then used Build & Deploy option of workbench to create and deploy the jar file. I then created the container using the jar file and got the end point that I am using to access the rule engine from my client application. At this point every thing is working fine and I am able to fire the rules remotely.
My requirement is to modify the rules file (.drl) outside the workbench, let's say in notepad and update the container with this new drl file. Is there an easy way to create the jar file programmatically that i can deploy to the central maven repository? I can then run the KIE scanner to look for the latest version of my jar file and automatically update my container. Or is there another recommended way to update the running container with an updated .drl file?
My client application is not in Java so I am not looking for an integrated solution where I can write java code to create the knowledge base and use kie builder to build the drl file.
Is there an easy way to create the jar file programmatically that i can deploy to the central maven repository?
2 options that I can think of, one "easy" and one not so much:
Option 1
Use Maven and the maven drools plugin (you don't have to write Java code, just create your maven project and run mvn package to get a jar. See here: https://docs.jboss.org/drools/release/6.0.1.Final/drools-docs/html/KIEChapter.html#KIEModuleIntroductionBuildingIntroductionSection
Option 2
A JAR file is simply a zip file with a specified structure. That means that you should be able to update your whatever.drl file, put it in the directory structure that the KIE server expects and deploy it.
For instance, create a directory structure like:
META-INF/kmodule.xml
com/site/project/drools/rules/myrule/SomeRule.drl
Zip those files into somefile.jar and deploy it.
I'm working on a liferay portlet developed by another contractor. The project was designed in maven, with all the service classes (service-builder) in a seperate bundle. So when the project is called foo, there are projects like:
foo-portlet
foo-service
foo-service-portlet
foo-service-portlet-service
I don't really understand why the services are splitted like that. And why they aren't part of foo-portlet.
The service.xml is located in foo-service-portlet/src/main/webapp/WEB-INF. There's no build.xml so running service-builder using ant won't work.
Now, we're facing some troubles because of https://issues.liferay.com/browse/MAVEN-37 and I'd like to turn the services into an ant project.
I thought about:
Creating another portlet using the plugins-sdk
Copying the old service.xml and overriding the new one
Running service-builder with ant
Copying the old impl classes and overriding the new ones
Rerunning the service builder using ant
But what will hapen when I deploy the new portlet? Will liferay realize that the tables defined are already there? The old code is already in production and has a lot of data which may not be lost!
Thanks in advance, Fabi.
Btw., still using liferay 6.1.20 EE.
I have created a Dynamic web project which also uses drools for providing some functionality. When i put the WAR file in Tomcat7 and the server, the drools part does not work.
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
After this line which is first line relating to drools, nothing happens.
Is some configuration required to run my project containing drools 5.5.0 Final in the Tomcat7.
Please help me. I am badly stuck and I am new to drools.
You'll have to add some facts to the working memory and execute(fire) the rules. Check out these examples on GitHub
P.S. Probably not related to Tomcat in any way. Might be worth while to try getting the rules executed from command line app first.
You need to check all the dependencies that are added to your web application (WEB-INF/lib) make sure that drools has all the required deps there, because if not it will not be able to create the knowledge builder. Most of the time if it is failing is because that you forgot to add the deps in the web app.
The following project in GitHub is a web application, containing some REST-style endpoints for validating IBANs. It uses Drools 5.5 to perform that evaluation.
https://github.com/gratiartis/sctrcd-payment-validation-web/
It generates a .war which can be loaded into Tomcat, and could be a useful starting point. The knowledge base is wrapped within a Spring service:
https://github.com/gratiartis/sctrcd-payment-validation-web/blob/master/src/main/java/com/sctrcd/payments/validation/RuleBasedIbanValidator.java
Following through how that creates a knowledge base and session might help you see where your code is going wrong.
As a bonus, you can run it up in Tomcat using "mvn tomcat7:run" to test it out immediately.
