Sorry to bring up a really old thread, but I hate it when people don't post
their final solutions. Hopefully this can help someone else. We control
the env to deploy to using a profile and connect to the deployment manager
via soap. A custom script (jython) was written that maps the app to all the
"web servers" as part of the deploy. The only config that needs to be put
into each project is what cluster and virtual host to deploy to, per env.
Then we can deploy from our CI server using a command like "mvn clean
integration-test -Dwas6-deploy=dev"
In our corporate parent pom, I have this in the plugin management section:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>was6-maven-plugin</artifactId>
<version>1.1</version>
<executions>
<execution>
<id>integration-test</id>
<phase>integration-test</phase>
<goals>
<goal>wsDefaultBindings</goal>
<goal>wsUninstallApp</goal>
<goal>installApp</goal>
<goal>wsAdmin</goal>
</goals>
</execution>
</executions>
<configuration>
<updateExisting>false</updateExisting>
<args>
<param>${was6.deploymentMgrPath}</param>
<param>${was6.applicationName}</param>
<param>${was6.targetCluster}</param>
</args>
</configuration>
</plugin>
In the settings.xml file, we have this:
<profile>
<id>was6-auto-deploy-base</id>
<activation>
<property>
<name>was6-deploy</name>
</property>
</activation>
<properties>
<was6.wasHome>/opt/WebSphere/AppServer</was6.wasHome>
<was6.conntype>SOAP</was6.conntype>
<was6.language>jython</was6.language>
<was6.script>/path/to/script/was_script.py</was6.script>
</properties>
</profile>
<profile>
<id>was6-auto-deploy-dev</id>
<activation>
<property>
<name>was6-deploy</name>
<value>dev</value>
</property>
</activation>
<properties>
<was6.host>wasdevadmin.example.com</was6.host>
<was6.port>8879</was6.port>
<was6.deploymentMgrPath>/opt/WebSphere/AppServer/profiles/DmgrDev</was6.deploymentMgrPath>
</properties>
</profile>
In the pom.xml of the ear, this is the config that's added:
<profile>
<id>was6</id>
<activation>
<property>
<name>was6-deploy</name>
</property>
</activation>
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>was6-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</profile>
<profile>
<id>was6-dev</id>
<activation>
<property>
<name>was6-deploy</name>
<value>dev</value>
</property>
</activation>
<properties>
<was6.virtualHost>DEV_VIRTUAL_HOST_NAME</was6.virtualHost>
<was6.targetCluster>DEV_CLUSTER_NAME</was6.targetCluster>
<!-- see http://jira.codehaus.org/browse/MWAS-33 -->
<was6.server>DEV_CLUSTER_NAME</was6.server>
<!-- This is how the ear is identified in websphere -->
<was6.applicationName>${project.artifactId}</was6.applicationName>
</properties>
</profile>
The custom script that I wrote is:
import sys
def syncNodes():
nodes = AdminControl.queryNames("WebSphere:type=NodeSync,*").split()
for node in nodes:
AdminControl.invoke(node, "sync")
#print node
# end sync nodes
def startAppOnCluster(appName,clusterName):
members = getClusterMembers(cluster)
for clusterMember in members:
changeAppOnClusterMember(appName, clusterMember, 'startApplication')
# this will return a list of the cluster members for the given cluster
def getClusterMembers(cluster):
members = []
for clusterMember in AdminConfig.list('ClusterMember',
AdminConfig.getid( '/ServerCluster:'+clusterName)).split(lineSeparator):
members.append(clusterMember[:clusterMember.find("(")])
return members
# Change an application on a specific cluster
def changeAppOnClusterMember(appName, clusterMember, command):
appMan =
AdminControl.queryNames('process='+clusterMember+',type=ApplicationManager,*')
#print "app man"+appMan
try:
print "Changing " + appName + " on " + clusterMember + " running
command " + command
if(AdminApp.isAppReady(appName)) :
AdminControl.invoke(appMan, command, appName)
else:
print "ERROR : app. not ready "
except:
print "ERROR: couldn't change " + appName + " on " +
clusterMember
else:
print "Done!"
# this will parse out the values for a webserver into a dictionary (map)

str(values['server'])
print "argument is: " + argument
AdminControl.invoke(generator, 'generate', argument + " true")
AdminControl.invoke(generator, 'propagate', argument)
# this is the code that gets run when this script is executed
if (len(sys.argv) == 3):
dmgrPath = sys.argv[0]
appName = sys.argv[1]
cluster = sys.argv[2]
print "Modifying websphere install. Using app name '" + appName + "',

else:

# end script
YYMV, but this might help as a starting point.
