Tapestry JumpStart

Orientation

This page relates to JumpStart v3.8 and v3.9. Click here for newer versions.

Web source is in these locations:

	web

	|---src

	    |---main

	        |---java

	            |---jumpstart

	                |---web

	                    |---components   --> .java for components eg. Layout.java

	                    |---pages        --> .java for pages eg. UserSearch.java

	                    |---services     --> .java for services eg. BusinessServicesLocator.java

	        |---webapp

                    |---components           --> .tml for components eg. Layout.tml

                    |---pages                --> .tml for pages eg. UserSearch.tml

                    |---WEB-INF              --> .properties file for application-wide messages

Business source is in these locations:

	business

	|---src

	    |---main

	        |---java                     --> .properties file for business messages

	            |---jumpstart

	                |---business

	                    |---domain       --> .java for business (entities and services and )

	        |---resources

	            |---META-INF             --> .xml for persistence descriptor

Eclipse compiles the java source to bin/ and runs our Ant file exploder.xml file to copy all the necessary items to exploded/, which holds an "exploded" EAR file with this structure:

	exploded

	|---jumpstart-min.ear

	    |---jumpstart-min.jar            --> the business layer

	    |---jumpstart-min.war            --> the web layer

You can see how the exploder has this been configured by displaying the project's properties and choosing Builders.

A tour To learn more, open the project in Eclipse, locate README-HOME-PAGE in web/src/main/webapp/WEB-INF/ and start the tour. Afterwards, you can use this page to get more info and as a handy reference.

Reference These files describe the application structure. They rarely need to change.

enterprise/src/main/resources/META-INF/application.xml tells the application server we have a WAR and a JAR, and it says the WAR handles URLs involving jumpstart.

web/src/main/webapp/WEB-INF/web.xml tells the web server how to handle jumpstart URLs - it says filter them through Tapestry!

business/src/main/resources/META-INF/MANIFEST.MF tells the EJB3 server which classpath entries we need (in addition to the ones it provides).
business/src/main/resources/META-INF/persistence.xml tells the EJB3 server how we want to persist data - the datasource name and some settings.

The only one you're likely to change is persistence.xml. See Tips for more on that.

Tapestry expects a class called AppModule to exist to describe services we want added in:

jumpstart.min.web.services.AppModule

Examples Here are the pieces involved in logging in:

Layer	Source file	Location
Web messages	app.properties	web/src/main/webapp/WEB-INF/
View	LogIn.tml	web/src/main/webapp/pages/theapp/
Controller	LogIn.java	web/src/main/java/jumpstart/web/pages/theapp/
Services	ISecurityFinderSvcLocal.java SecurityFinderSvc.java	business/src/main/java/jumpstart/business/domain/security/iface/ business/src/main/java/jumpstart/business/domain/security/
Entity	User.java	business/src/main/java/jumpstart/business/domain/security/
Business messages	messageDefs.properties	business/src/main/java/

Here are the pieces involved in editing a user. Many are the same as for logging in:

Layer	Source file	Location
Web messages	app.properties	web/src/main/webapp/WEB-INF/
View	UserEdit.tml	web/src/main/webapp/pages/theapp/security/
Controller	UserEdit.java	web/src/main/java/jumpstart/web/pages/theapp/security/
Services	ISecurityFinderSvcLocal.java SecurityFinderSvc.java ISecurityManagerSvcLocal.java SecurityManagerSvc.java	business/src/main/java/jumpstart/business/domain/security/iface/ business/src/java/main/jumpstart/business/domain/security/ business/src/java/main/jumpstart/business/domain/security/iface/ business/src/java/main/jumpstart/business/domain/security/
Entity	User.java	business/src/main/java/jumpstart/business/domain/security/
Business messages	messageDefs.properties	business/src/main/java/

Tapestry locates components that aren't pages a little differently. For example, the "Layout" component:

Layer	Source file	Location
View	Layout.tml	web/src/main/webapp/components/theapp/
Controller	Layout.java	web/src/main/java/jumpstart/web/components/theapp/
