Installing a Developing Feature

Warning !

The content was not belongs to me, I just do some value addition to reference by explaining my project scenario with this. For clear understanding and deep learning go through references.

Carbon Features are set of Features which was developed for support of WSO2 Products, these are installed by default or manually. For manually installing those features we need to locate the location of repositories where those features are located. There is a common location available for all repositories in online, you just need to specify those repositories based on the carbon version of your product. This is for the people who want to access the features to do things.

So in my project perspective, I need to improve the “HL7 Feature” which currently under development. For this,

  1. First clone the repository containing the feature.For me it is carbon-meditation.
  2. Go to the component of relevant feature.For me it is carbon-mediation/components/business-adapters/ hl7/ org.wso2.carbon.business.messaging.hl7.common/ – (Actually only this part of main component is  modifying so I need to build it only, but it is better to build hl7 in case if we you modifying other or not).Build the HL7 “component”; component contains basic sources for the feature, about how it works and implementation, but features are consisting of several sub parts which are bundle separately when building this only.
  3. Then build “feature”; this will make a bundle with full feature combined with necessary dependencies additional to bundle and make the feature finalized. For my case it is in carbon-mediation/features/business-adapters/org.wso2.carbon.hl7.feature/

WHILE TESTING WITH

When building COMPONENT and FEATURE, it will generate a zip file in the target of feature which is actually bundling the whole feature with necessary dependencies and configuration files. Based on features we need to unzip the zip file and  add contents to the working server. For my case it doesn’t contains any config file so I just unzip and copy the jar files to the /repository/components/dropins/ and restart the relevant server. It will use the feature which is stored in dropins by doing necessary actions. Actually for my case it will copy those jars to /repository/components/plugins/, but incase if any configuration found. It will do that also. By doing this we can test the system.

[this is based on Inosh Goonerwardana’s Mentoring]

FOR FINAL DELIVERY

For my project perspective, when building COMPONENT and FEATURE,It  will make HL7 feature available at /home/user/.m2/repositories/ (the place where all installed repositories installed, and this is place where maven lookup in search of repositories.).Like this based on your feature you build necessary part and make it available at /home/user/.m2/repositories/.

To make this accessible by desired  feature installing system in Management console we need to add the particular SNAPSHOT version/latest version  of required feature using the tag  in the carbon-feature repository and build it. When building it will add  the SNAPSHOT/latest version of feature to p2-repo. Then by using local repositories we can install features. [1]
