Network Deployment (Distributed operating systems), v8.0 > New features > Overview and new features: Developing and deploying

Access the samples

The product offers samples that demonstrate common enterprise application tasks. Many samples also provide instructions for deployment and coding examples.

New feature: The product provides samples in two ways:

Plants By WebSphere sample installed with the product

If you select to install samples when installing the product and when creating an application server profile, the Plants By WebSphere application is included with the product. The application demonstrates several Java EE functions, using an online store that specializes in plant and garden tool sales.

See Install the Plants By WebSphere sample.

Samples downloadable from the Samples, v8.0 information center

The product provides component-specific samples that you can download at any time from a download site.

Install the Plants By WebSphere sample

To install the Plants By WebSphere sample, perform the following steps.

1. Install the product.

   When specifying installation or profile options, select to install the sample applications.

   By default, only the Plants By WebSphere sample is installed in...

   WAS_HOME/samples

   A Plants By WebSphere pre-built enterprise archive named pbw-ear.ear is in the /samples/PlantsByWebSphere/pbw-ear/target directory.

   Installation instructions are in the /samples/PlantsByWebSphere/docs directory.

   You can build or modify the sample source code to support your project. The source code is in a src directory.

2. To run the sample in a distributed WAS ND environment, install and configure the samples in a stand-alone application server profile installation, and then add the stand-alone application server profile as a managed node of the dmgr cell.

   You can use a dmgr administrative console or wsadmin addNode command to make an application server a managed node of a dmgr. For the wsadmin addNode command, use the dmgr_host argument with the -includeapps and -includebuses options.

   For example:

   addNode.sh/bat dmgr_hostname -includeapps -includebuses
   

   where dmgr_hostname is name of the computer that hosts your dmgr profile.

3. Start the application server.

Available samples

Samples that you can download include, for example, the following materials:

Service Component Architecture (SCA) samples

The SCA samples support SCA specifications. SCA services are packaged in JAR files that you import as assets to the product repository and then add as composition units to business-level applications.

New feature: Download SCA.zip, or individual sample files, to a directory on your workstation. You might create the /samples/sca directory path on your workstation and download SCA sample files to that directory path.

We must deploy SCA sample files as assets of a business-level application to a v8.0 server or cluster or to a v7.0 target that is enabled for the Feature Pack for SCA. The SCA/installableApps directory of SCA.zip contains prebuilt archives that you can deploy as assets. The other directories contain sample-specific source files, scripts, and instructions for building deployable archives.

Communications Enabled Applications (CEA) samples

The CEA sample applications provide two main services, telephony access and multi-modal web interaction. Use this collection of sample applications to explore the services and to use as a starting point when developing your own communication enabled applications.

OSGi samples

The OSGi samples help you develop and deploy modular applications that use both Java EE and OSGi technologies.

XML samples

The XML samples demonstrate use of the XML API and supported specifications.

Internationalization service sample

The Internationalization service sample demonstrates how to use the internationalization service in Java EE applications, specifically within servlets and enterprise beans.

Web services samples

These samples demonstrate both JAX-RPC and Java API for XML Web Services (JAX-WS) web services that use Java Platform, Enterprise Edition (Java EE) beans and JavaBeans components.

The JAX-WS web service samples demonstrate the implementation of one-way and two-way web services that highlight the use of web services standards such as WS-Addressing (WS-A) , WS-Reliable Messaging (WS-RM), and WS-Secure Conversation (WS-SC) and the SOAP Message Transmission Optimization Mechanism (MTOM) technology.

Service Data Objects (SDO) sample

This sample demonstrates data access to a relational database through Service Data Objects (SDO) and Java DataBase Connectivity (JDBC) Mediator technologies.

Download samples New feature:

We can download samples from the Samples, v8.0 information center.

1. Go to the Samples, v8.0 information center.
2. Determine which samples to download.

3. On the Downloads tab for the samples that you want, click a Download Sample link.

4. In the authentication window, click OK.
5. Download the compressed file, or individual sample files, to a directory on your workstation.

   You might create the /samples/sample_type directory path on your workstation and download the sample files to that directory path.

Many sample compressed files have an /installableApps directory that contains deployable prebuilt archives. Other directories contain files such as sample-specific source archives, scripts, and instructions for building deployable archives.

To deploy them to the application server, you can use the administrative console or use the install script in...

WAS_HOME/samples/bin

Limitations of the samples

• The samples are for demonstration purposes only.

  The code provided is not intended to run in a secured production environment. The samples support Java 2 Security, therefore the samples implement policy-based access control that checks for permissions on protected system resources, such as file I/O.

  The samples also support administrative security.

• Many of the samples connect to an Apache Derby database using the embedded framework of Apache Derby. The embedded framework of Apache Derby has a limitation that only one Java virtual machine (JVM) can access a given database instance. As a result, in a clustered application server environment, the second server in the node fails to start the sample applications, because the first server (JVM) already holds a connection to that database instance.

  For applications that require multiple Java virtual machines to access the same Apache Derby instance, use the Apache Derby networkServer framework.
