Question 6. How To Deploy And Undeploy Applications In Glassfish Command Line?

Answer :

The technique of configuring and permitting applications to run inside the GlassFish Server

framework is referred to asdeployment.

To Obtain the Sample Application

Download a replica of thehello.Warsample software fromhttp://glassfish.Java.Net/

downloads/quickstart/hey.Conflict.

Save thehello.Warfile in the directory of your choice.

This directory is referred to as sample-dir

To Deploy the Sample Application From the Command Line

The pattern utility ought to be available earlier than you start this challenge. To down load the sample, see “To Obtain the Sample Application” on web page eight. At least one GlassFish Server domain must be started out before you deploy the sample software.

Run the asadmin installation command.

The wellknown form for the command is as follows:

as-installation/bin/asadmin set up struggle-name

To installation the good day.Warfare sample, the command is as follows:

as-set up/bin/asadmin installation sample-dir/hey.Struggle

Access thehelloapplication by using typing the subsequent URL in your browser:

http://localhost:8080/hello

The application's start web page is displayed, and you are triggered to type your name.

Type your name and click on Submit.

The utility displays a custom designed reaction, giving you a private Hello.

To List Deployed Applications From the Command Line

Run the asadmin list-applications command:

as-installation/bin/asadmin list-applications

To Undeploy the Sample Application From the Command Line

Run the asadmin undeploy command.

The preferred shape for the command is as follows:

as-install/bin/asadmin undeploy war-name

Forwar-name, use the literal hello, no longer the overall hey.Warname.

For the whats up.Battle instance, the command is as follows:

as-set up/bin/asadmin undeploy whats up

Question 7. How To Deploy And Undeploy Applications By Using The Administration Console?

Answer :

Question 8. How To Deploy And Undeploy Application Automatically In Glassfish?

Answer :

To Deploy the Sample Application Automatically

You can deploy programs routinely by way of placing them within the  as-install/domains/domain-call/autodeploydirectory, wheredomain-nameis the call of the area for which you need to configure computerized deployment.

For this situation, use the default domain, domain1:

as-installation/domain names/domain1/autodeploy

The sample software should be available earlier than you begin this challenge.

Copy the applicationWAR report to theas-deploy/domains/domain-call/autodeploydirectory.

On UNIX, Linux, and Mac OS X systems, type this command:

cp sample-dir/howdy.Struggle as-installation/domain names/area-name/autodeploy

OnWindows structures, kind this command:

replica sample-dirhello.Warfare as-installdomainsdomain-nameautodeploy

GlassFish Server robotically discovers and deploys the utility. The default URL for the application is as follows:

http://localhost:8080/hiya/

To Undeploy the Sample Application Automatically

Change to the domain'sautodeploydirectory.

Cd as-installation/domain names/area-call/autodeploy

Delete the sample software'sWAR file to undeploy and eliminate the utility.

On UNIX, Linux, and Mac OS X systems, type this command:

rm hello.Battle

OnWindows systems, type this command:

del hi there.Warfare
