Examples

Pax Web includes a set of examples that demonstrates its usage.

Hello World (Http Service usage)

This example shows you how to register a servlet and resources using the standard Http Service. Source code can be found in SVN.
Once the example is started (see below) you can point your web browser to http://localhost:8080/helloworld/hs.

You can simply start the example by using Pax Runner using one of the two methods below:

Download the provision file

1. Download https://scm.ops4j.org/repos/ops4j/projects/pax/web/samples/provision/src/main/resources/sample-helloworld-hs.bundles to an arbitrary location
2. Start Pax Runner from the directory you have downloaded the provision file:

   pax-run sample-helloworld-hs.bundles
   

Direct

pax-run scan-file:jar:mvn:org.ops4j.pax.web.samples/provision!/sample-helloworld-hs.bundles

Hello World (Web Container usage (extended http service))

This example shows you how to register servlets, resources, filters, listeners and error pages using the extended Http Service, WebContainer. Source code can be found in SVN.
Once the example is started (see bellow) you can point your web browser to

• http://localhost:8080/helloworld/wc — to see the result of servlet invocation being wrapped by a filter (see example source for details). In this case the filter is applied based on an url pattern.
• http://localhost:8080/helloworld/wc/sn/ — to see the result of servlet invocation being wrapped by a filter (see example source for details). In this case the filter is applied based on a servlet name.
  To see that a different filter was applied you can check out the page title for each of the above urls.
• http://localhost:8080/helloworld/wc/error/create?type=java.lang.IllegalArgumentException — to see how the error page will be triggered when a servlet throws an exception. The exception to be thrown is specified by the type parameter. The error page will display all servlet request attributes related to an exception page as specified by Servlet spec.
• http://localhost:8080/helloworld/wc/a.page.that.not.exist — to see how the error page will be triggered based on the error type (404 in this case — page not found).

To verify that the listener (a ServletRequestListener is working you can repeat the request and check out the bottom of the page that displays a counter for the request made to the server.

You can simply start the example by using Pax Runner using one of the two methods below:

Download the provision file

1. Download https://scm.ops4j.org/repos/ops4j/projects/pax/web/samples/provision/src/main/resources/sample-helloworld-wc.bundles to an arbitrary location
2. Start Pax Runner from the directory you have downloaded the provision file:

   pax-run sample-helloworld-wc.bundles
   

Direct

pax-run scan-file:jar:mvn:org.ops4j.pax.web.samples/provision!/sample-helloworld-wc.bundles

Hello World (JSP support (extended http service))

This example shows you how to register jsps using the extended Http Service, WebContainer. Source code can be found in SVN.
Once the example is started (see bellow) you can point your web browser to

• http://localhost:8080/helloworld/jsp/helloworld.jsp — to see the result of invoking a jsp.
• http://localhost:8080/helloworld/jsp/helloworld-tld.jsp/ — to see the result of invoking a jsp that uses taglibs. not yet implemented

You can simply start the example by using Pax Runner using one of the two methods below:

Download the provision file

1. Download https://scm.ops4j.org/repos/ops4j/projects/pax/web/samples/provision/src/main/resources/sample-helloworld-jsp.bundles to an arbitrary location
2. Start Pax Runner from the directory you have downloaded the provision file:

   pax-run sample-helloworld-jsp.bundles
   

Direct

pax-run scan-file:jar:mvn:org.ops4j.pax.web.samples/provision!/sample-helloworld-jsp.bundles

Backup Department Store example

This example shows you standard Http Service usage via the Department Store example from Backup. Source code can be found in SVN.
Once the example is started (see bellow) you can point your web browser to http://localhost:8080/deptStore.

You can simply start the example by using Pax Runner using one of the two methods bellow:

Download the provision file

1. Download https://scm.ops4j.org/repos/ops4j/projects/pax/web/samples/provision/src/main/resources/sample-deptstore.bundles to an arbitrary location
2. Start Pax Runner from the directory you have downloaded the provision file:

   pax-run sample-deptstore.bundles
   

Direct

pax-run scan-file:jar:mvn:org.ops4j.pax.web.samples/provision!/sample-deptstore.bundles
