When installing an application and you want to know all the options for binding resources and virtual hosts etc in your Jython script, the quickest way to learn is to record a deployment using the console.

In my example I am using WebSphere Application Server 8, but the principle is the same fro WebSphere version 7.

Lets us turn on the ability to record the Jython and deploy a ample application that is used in my training course: WebSphere Application Server 8 Network Deployment Essentials.

Setting up the console to record Jython

1. Log into the Administrative Console and navigate to the “System Administration” section and click “console Preferences”

1. Check the “Enable command assistance notifications” check box. If you want to log to <was_profile_root>/logs /<server_name> then check “Log command assistance commands” check box as well.

1. Click Apply and Save.

We can now see the full code required to deeply an application.

Deploying EShoppe.war

In my course module called the Application Deployment Howto and another module called Administrative scripting Howto, I cover how to automatically deploy a WAR file. We can either deploy a War file or EAR file in WAS. The differences of both are also covered in my course theory PPT slides that come with the full course. The course is available for officially normally $249, but currently $149. It is limited to only 1000 sales world wide for this price, so get in quick as it is selling fast. To buy this course, send me a contact form via http://www.the middlewareshop.com. After July 31^st 2012 the source can be purchased online.

Below is a quick, brief example.

1. Navigate to the “Applications” Section in the administrative console, then expand “Application Types” then click

1. In the “Enterprise Applications” view click “Install”

1. Either browse locally or remotely to locate your WAR file

1. Click Next
2. Choose fast path
3. Follow the required to map resources and modules. You can see some of the steps below:

1. On the summary page you will see the option “View administrative scripting commands for last action”. These are also available in the logs folder in a file called:

1. Below is an example of the Jython that might be generated. You can use this recoded Jython as a base for your script.

Configuring the build file takes some effort. But WebSphere eases the task to a great extent by providing a feature which allows you to record the changes you make through admin console as wsadmin scripts. This is explained later. For now, when you deploy EShoppe application through admin console and use the recording feature, this is what you get. *************************************************************************** # [2/25/12 12:53:39:370 IST] Enterprise Applications > Enterprise Applications > Available resources AdminApp.install(‘EShoppe.war’, ‘[ -nopreCompileJSPs -distributeApp -nouseMetaDataFromBinary -nodeployejb -appname EShoppe_war -createMBeansForResources -noreloadEnabled -nodeployws -validateinstall warn -noprocessEmbeddedConfig -filepermission .*\.dll=755#.*\.so=755#.*\.a=755#.*\.sl=755 -noallowDispatchRemoteInclude -noallowServiceRemoteInclude -asyncRequestDispatchType DISABLED -nouseAutoLink -noenableClientModule -clientMode isolated -novalidateSchema -contextroot /eshoppe -MapResRefToEJB [[ EShoppe.war "" EShoppe.war,WEB-INF/web.xml jdbc/eshoppe javax.sql.DataSource jdbc/eshoppe "" "" "" ]] -MapModulesToServers [[ EShoppe.war EShoppe.war,WEB-INF/web.xml WebSphere:cell=appsrv01node01,node=node01,server=server1 ]] -MapWebModToVH [[ EShoppe.war EShoppe.war,WEB-INF/web.xml default_host ]] -CtxRootForWebMod [[ EShoppe.war EShoppe.war,WEB-INF/web.xml /eshoppe ]]]’ ) # [2/25/12 12:53:47:572 IST] Enterprise Applications > Enterprise Applications > Available resources AdminConfig.save() ***************************************************************************

In my Course I show you how to use this information to write object oriented Jython code that is much better then the code you see on the internet.

This set of articles shows the process, errors included that show how I learned to install WebSphere 8 ND.

The article is broken into several parts, some parts you can skip as they may only contain my problem solving data. Any article in the series that has a warning in the top part of the article is a doc that you should skip and just review if you are looking for answers for problem solving techniques.

To being our article series, we need to locate and install the latest version of IBM Installation Manager.

https://www-304.ibm.com/support/docview.wss?uid=swg24030152#downloads

Click on the Download link located in the page and select you preferred OS type

Read and Accept the terms and conditions.

Once accepted you will be prompted to choose a location to save the IM installable.

It took my download some minutes to download the 114MB install.

OK locate the downloaded binaries. In my case this is /var/apps/

Run the following command

unzip agent.installer.linux.gtk.x86_1.5.0.20110909_1200.zip

Result

We are going to run the IBMIM (IBM installation Manager) located the root directory of the unzipped binaries i.e. the listing above you can see the install command which were are going to use. The installation location will be /opt/IBM/ InstallationManager

For computers without Internet access an update cannot be applied as the installation is running

1. Open a command prompt to the directory where you extracted compressed file.
2. Run the command to update Installation Manager:

Windows: installc -acceptLicense
Linux, UNIX, IBM i, and z/OS: ./installc -acceptLicense

For computers with Internet access

1. Create the file setSearchForUpdates.xml
2. Add the content:

<?xml version=”1.0″ encoding=”UTF-8″?>
<agent-input>
<preference value=’true’ name=’com.ibm.cic.common.core.preferences.searchForUpdates’/>
<preference value=’true’ name=’offering.service.repositories.areUsed’/>
</agent-input>

For information about preferences com.ibm.cic.common.core.preferences.searchForUpdates and offering.service.repositories.areUsed see: http://publib.boulder.ibm.com/infocenter/install/v1r4/index.jsp?topic=/com.ibm.silentinstall12.doc/topics/r_silent_prefs.html.

3. Save the file.
4. Open a command prompt to the eclipse\tools subdirectory located in the directory where Installation Manager is installed.
5. Run the command to update Installation Manager:

Windows: imcl.exe input setSearchForUpdates.xml -acceptLicense
Linux, UNIX, IBM i, and z/OS: ./imcl input setSearchForUpdates.xml -acceptLicense

AttributeError: instance of 'JVMModifier' has no attribute '_JVMModifier__eJFN'

Solution:

In this example, I had declared in my classes instance variable but it had a syntax error. AttributeError: instance of ‘JVMModifier’ has no attribute ‘_JVMModifier__eJFN’. What this means Is that the class called JVMModifier has an attribute or class instance variable that does not exist. So in this case __eJFN did not exist. This was because I had declared, self.eJFN  when self.__eJFN was being referred to in my code.

When looking at the code, I was able to see that I had a call to an object’s method. My Jython  had an error where the jython class method I was using was miss-spelt.

Error:

Name for command setJVMProperties.

Reason, well it was quite simple the name I had passed as the node name was “Node01″ instead of “node01″ all about case. But the error was very misleading as I was passing a nodeName variable and a serverName variable and the code was reporting to me the wrong parameter. I guess it got confused about how to display the appropriate param error. Well I thought I would add the error and my solution to help those jython enthusiasts trying to tame WAS.
Result:
