weblogic server script to deploy application programettically

Am looking for an option to deploy application(EAR/WAR/JAR) on weblogic server through script, where the script is executed through Java main class.

I have tried to achieve the same through Java like:

private static final String wlUsername = "'weblogic'";
private static final String wlPassword = "'welcome1'";

private static void connect() {
StringBuffer buffer = new StringBuffer();
buffer.append("connect(");
buffer.append(wlUsername);
buffer.append(",");
buffer.append(wlPassword);
buffer.append(")");
log.debug("connect: "+buffer.toString());
interpreter.exec(buffer.toString());
}


private static void createServers() {
StringBuffer buf = new StringBuffer();
buf.append(startTransaction());
buf.append("man1=create('msEmbedded1','Server')\n");
buf.append("man2=create('msEmbedded2','Server')\n");
buf.append("clus=create('clusterEmbedded','Cluster')\n");
buf.append("man1.setListenPort(8001)\n");
buf.append("man2.setListenPort(9001)\n");
buf.append("man1.setCluster(clus)\n");
buf.append("man2.setCluster(clus)\n");
buf.append(endTransaction());
buf.append("print ‘Script ran successfully ...’ \n");
interpreter.exec(buf.toString());
}

private static String startTransaction() {
StringBuffer buf = new StringBuffer();
buf.append("edit()\n");
buf.append("startEdit()\n");
return buf.toString();
}

private static String endTransaction() {
StringBuffer buf = new StringBuffer();
buf.append("save()\n");
buf.append("activate(block='true')\n");
//buf.append("dumpStack()");
return buf.toString();
}

public static void main(String[] args) {
connect();
enableMbeanServer();
createServers();
}

private static void enableMbeanServer(){
StringBuffer buf = new StringBuffer();
buf.append(startTransaction());
buf.append("set('CompatibilityMBeanServerEnabled', 'true')");
buf.append(endTransaction());
buf.append("shutdown()");
connect();
buf.append("print ‘CompatabilityMBeanServer enabled successfully ...’ \n");
interpreter.exec(buf.toString());
}


But, end up with the below exception:

20:41:59.927 DEBUG [main][com.fedex.interfaces.wls.WLSTRunner] connect: connect('weblogic','welcome1')
Connecting to t3://localhost:7001 with userid weblogic ...

The CompatabilityMBeanServer is not initialized properly.
This might happen if the CompatabilityMBeanServer is
disabled via the JMXMBean.

To view the root cause exception use dumpStack()

WLST detected that the RuntimeMBeanServer is not enabled. This
might happen if the RuntimeMBeanServer is disabled via the JMXMBean.
Please ensure that this MBeanServer is enabled. Online WLST cannot
function without this MBeanServer.

Any suggestion or any idea how to invoke deploy/undeploy task from Java?

Answer

You can use Weblogic Ant task instead of writing an application to do that. This is Weblogic Ant Task docs . You can follow this example as well.

To restart weblogic, check the reference

<target name="start-server">
  <wlserver dir="./config" host="127.0.0.1" port="7001" action="start"/>
</target>
