The section covers the setup via download or custom build. If you need configuration detail info or information on how to setup your ide correctly please follow the links in the navigation to the correct section. #Setup overview ## General Setup Information Ext-Scripting has a complete appendix list over all [configuration and setup](./configentries.html) options as well as [example configurations](./exampleconfig.html). For a quick overview please visit the following links. If you need detailed setup information, then read further on. ## Links #Checklist For a short checklist of setup steps please follow [ this link](./setupSteps.html). For a detailed setup guide, please continue reading. #Download With version 1.0.x Ext-Scripting provides all necessary artifacts as download artifacts to get quickly started. A kickstart project is provided which can be used as shell for your own projects. For Download information please visit the [ download page](./download.html). Once you downloaded the necessary artifacts please check the [manual setup section](#Manual_Setup) of this document. #Checkout and Build While Ext-Scripting is already in stable state, the best way to get started is probably to checkout and build Ext-Scripting yourself from the latest codebase. All other installation steps will have this step as prerequisite if you want to use the latest codebase instead of one of the beta releases! First you have to check out the latest codebase from [ http://svn.apache.org/repos/asf/myfaces/extensions/scripting/trunk ](http://svn.apache.org/repos/asf/myfaces/extensions/scripting/trunk) via a subversion client. Make sure you have following requirements fulfilled before checking out: After checkout, a full build can be obtained from the root directory of your checkout via mvn clean install. Once finished, a valid build is installed, which can be used further on. Additionally you can find two blueprint projects which you can use as starting points for your own projects under <checkoutDir>/examples , which can be started viamvn jetty:run-exploded. The now generated files either can be used to be included in a maven install or be included manually (please go to the next section for detailed setup instructions) #Setup of Ext-Scripting ## Requirements Before setting up Ext-Scripting for your project make sure following requirements are met. ## Setup While one of the aims of Ext-Scripting was to enable an easy setup, for now it was not entirely possible for now to get a plug and play configuration. Several configuration steps have to be performed. ## Preparations via Apache Maven 2 The easiest way once Extension scripting is compiled is probably a setup via Apache Maven 2 Depending on your configuration and preferred JDK version you can add following entries to your Maven pom.xml to enable Ext-Scripting MyFaces 2.1+ org.apache.myfaces.extensions.scripting extscript-myfaces20-bundle 1.0.5 Additional language libraries You have to add following artifacts to your dependency list for additional language support org.codehaus.groovy groovy-all 1.7.1 For Groovy support (version number may vary) org.scala-lang scala-library 2.9.1 org.scala-lang scala-compiler 2.9.1 For Scala support. For OpenWebbeans support please add following entry: org.apache.myfaces.extensions.scripting extscript-cdi 1.0.5 ## Manual Setup If you do not like Maven or you prefer a manual setup, Ext-Scripting provides convenient meta bundles. A manual setup comes down to the task of adding the appropriate meta bundle (extscript-myfaces20-bundle) to your WEB-INF/lib directory and adding a groovy-all.jar as additional dependency. For Scala support you have to add scala-library.jar and scala-compiler.jar to your WEB-INFU/lib. Note not adding those additional libs automatically will disable the respective language support. you can obtain both bundle jars after the build from: The additional language jars for the respective language can be obtained from the language distributions. However following dependencies must be met so that Ext-Scripting can work: For your convenience an empty webapp is provided within the [download page](./download.html) which delivers all needed dependencies to get you kickstarted. After having done that you are ready to setup the rest of the Ext-Scripting configuration manually as described in the section blow ## Preparing the Necessary web.xml Entries Most important step To enable Ext-Scripting you also have to add several entries to your web.xml file. First a context param has to be set which attaches the Ext-Scripting plugins to MyFaces Enables our scripting engine support plugins org.apache.myfaces.FACES_INIT_PLUGINS org.apache.myfaces.extensions.scripting.servlet.StartupServletContextPluginChainLoader Additional Optional Steps Ext-Scripting exposes a number configuration parameters which can be set via context parameters in your web.xml Adjust the web.xml Root source paths. Since the goal of Ext-Scripting is to provide scriptability to a running web application, it has to know where to find the sources. For this, a default location has been chosen according to the standards set by the Mojarra Groovy Extension. The location looks like: /WEB-INF/groovy as root location for Groovy files /WEB-INF/java as root location for java files. Following image displays the default locations: ![](images/ext-default-file.jpg) However in a normal development scenario, it is often undesirable to have the files located in a deployment location, and a pointer mechanism towards the actual source locations would be more desirable. To provide such a mechanism, Ext-Scripting allows two optional web.xml context parameters, which allow the rerouting of source locations of the supported languages! Additional comma separated loader paths to allow direct editing on the sources directory instead of the deployment dir org.apache.myfaces.extensions.scripting.groovy.LOADER_PATHS /src/main/webapp/WEB-INF/groovy Additional comma separated loader paths to allow direct editing on the sources directory instead of the deployment dir org.apache.myfaces.extensions.scripting.java.LOADER_PATHS /src/main/webapp/WEB-INF/java Additional comma separated loader paths to allow direct editing on the sources directory instead of the deployment dir org.apache.myfaces.extensions.scripting.scala.LOADER_PATHS /src/main/webapp/WEB-INF/scala Dynamic resource reloading Additionally Ext-Scripting allows the reloading of dynamic web resources like Facelets templates images css files etc... An additional config param is available to enable this functionality. resource paths for our custom JSF2 resource resolver org.apache.myfaces.extensions.scripting.resources.LOADER_PATHS ~/extensions-scripting3/examples/myfaces20-example/src/main/webapp a redirecting Facelet resource resolver which allows to pick up templates and resources from our source dir facelets.RESOURCE_RESOLVER org.apache.myfaces.extensions.scripting.jsf.facelet.ReroutingResourceResolver This sums up the quick install and setup guide, if you want more detailed setup examples and additional configuration entries go to our [Example Configurations](./exampleconfig.html) page, which shows a set of different configurations. Package Whitelisting The last possible config entry is the ability to whitelist packages. If you have set this option then only whitelisted packages will be picked up for dynamic recompilation With this option you can point your source dir to the normal compile source and mark special packages as dynamic (to isolate the dynamic part from the rest) To enable this option, add following entry to your web.xml: a comma separated whitelist of root packages which are compiled those and nothing else will be compiled during all compile stages, all other files stay permanently as they are org.apache.myfaces.extensions.scripting.PGK_WHITELIST org.apache.myfaces.groovyloader.blog,org.apache.myfaces.javaloader.blog ## Preparations for Openwebbeans From a Ext-Scripting perspective, dropping the extscript-cdi war into your libraries dir is enough to enable Openwebbeans support, however you have to have Openwebbeans installed properly which means you have to add a beans.xml file to your META-INF directory and you have to add following entry to your web.xml file: org.apache.webbeans.servlet.WebBeansConfigurationListener #Navigation Bottom [<<Back to the Start Page](./index.html) or [On to the Openwebbeans Spring Guide >>](./owbSpring.html)
