Introduction

Maven plugin to deploy a single war or ear to one or multi local or remote WebSphere Application Server (WAS) at a single build.
Tested on WAS 8.5
Requires: WebSphere Application Server installation on host box! But no need to be configured, nor running.

Requires: JDK 6 or later

How It Works

These are the known popular ways that you can programmly have your war/ear deployed to a running WebSphere Application Server:

JMX

Using IBM specialized JMX APIs you could not only retrieve the information of the apps, but also you can do deployment.

2 jars from WebSphere are required along with your build.

• com.ibm.ws.admin.client_x.x.x.jar (over 50MB)
• com.ibm.ws.orb_x.x.x.jar (about 2MB)

It does NOT support all options for deployment!

Monitored Directory Deployment

Deployment by adding your packages to a monitoredDeployableApps subdirectory of an application server or deployment manager profile.

For more information, please check: http://www-01.ibm.com/support/knowledgecenter/SSAW57_8.5.5/com.ibm.websphere.nd.doc/ae/trun_app_install_dragdrop.html

In order to deploy to a remote WAS, you'll have to copy/upload your packages to remote host first thru sftp or other approaches.

It's turned off by default.

Ant Tasks

WebSphere provides a set of built-in ant tasks, by using which you could also programmly have your packages deployed to WAS.

http://www-01.ibm.com/support/knowledgecenter/SSAW57_8.5.5/com.ibm.websphere.javadoc.doc/web/apidocs/com/ibm/websphere/ant/tasks/package-summary.html

Ant tasks are in the end been translated to jacl script and been executed in wsadmin client.

wsadmin client (what we are using)

wsadmin client tool is the most powerful and flexible tool from OPS' perspective, which locates in $WAS_HOME/bin/wsadmin.sh.

It supports 2 scripting languages: jacl (default) and jython (recommended).

It uses WebSphere built-in security (credencials) and file transfer protocal (no sftp is needed) for a remote deployment.

JMX and Ant Tasks approaches were also implemented in the beginning, but we had them removed before 1.0.2

Goal-deploy

The only goal of this plugin, it will:

1. Check if an application with the same name already installed on target server(s)/cluster(s)
   • Uninstall it if yes
2. Install the package to target server(s)/cluster(s)
3. Restart target server(s)/cluster(s)

Multi Target Servers

was-maven-plugin.properties

This property file contains the meta config for target WAS.
The section name will be used to identify each target WAS.

Please put was-maven-plugin.properties to the same folder as pom.xml, to make it available as ${project.basedir}/was-maven-plugin.properties

• pre-steps/post-steps can be used with both single target server and multi target servers
• All properties defined in properties section of pom or in was-maven-plugin.properties are available in pre-steps/post-steps ant tasks

Customized Jython Script File

This plugin also supports customized jython script if you need to tween the installation options, such server mappings.

You can copy-create it from the built-in one, or write a totally different one of you own.

Double braces for variables, such as: {{cluster}}, properties in was-maven-plugin.properties are all available as variables.

Sample Jenkins Job Configuration

Configure

Trigger

With Global Security Turned on

When Global Security is enabled on remote WAS (not under a same deployment manager), certificates of remote WAS need to be added to local trust store. We could configure WAS to prompt to add them to local trust store.

1. Open ${WAS_HOME}/properties/ssl.client.props
2. Change the value of com.ibm.ssl.enableSignerExchangePrompt to gui or stdin

• gui: will prompt a Java based window, this requires a X window installed.
• stdin: when using ssh, or on client linux without X window installed.

Change List

1.1.1

• Fixed issue of not starting application on standalone WAS (restartAfterDeploy=false)

1.1.0

• Fixed server mapping issue with cluster. Apps will be deployed to all servers that managed by the specified cluster.
• Web servers support, use webservers to specify the web server(s) that you want to bind. (but you still have to 'update web server plug-in configuration' by your self.)
• Added parameter deployOptions, expecting space-separated options such as -precompileJSPs -deployws, which will be prepended in the deployment options.
• Fixed issue about failOnError.
• Extracted some common code including websphere.py to was-util, which is also been used by was-gradle-plugin

1.0.12

• Fixed the issue about "Template 'jython\websphere.py' not found" specific for Windows.

1.0.11

• Fixed the issue with customized script.

1.0.10

• Added a boolean parameter restartAfterDeploy:
  • true to restart server after deploy
  • false to start application directly
  • Default: true

1.0.9

• Added support to override default javaoption in wsadmin client, in case you get OutOfMemoryError.

1.0.8

• Fixed single target WAS deployment issue.
• Not to check whether parent folder of deployment script been created or not.

1.0.7

• Removed preCompileJSPs options for deployment.

1.0.6

• Fixed multi-server deployment issue.

1.0.5

• Downgraded to use 1.5 build level, so that it can be used for older version of websphere.
• Fixed property resolving issue, properties in was-maven-plugin.properties are all available in custome scripts and pre/post steps.

1.0.4

• Added PARENT_LAST for application and web module and shared libs bindings.
• Added failonerror

1.0.3

• Removed private project specific logic. (it's the 1st working version for general projects for websphere deployment).
