Since WebCenter PS5, Oracle brings lots of standard task flows
inside WebCenter Spaces. Some of them are already registered within the
resource catalog and ready to use, most of them are also ready but you need to
add them to the resource catalog first for business users to utilize. But from
a developer standpoint, you may be interested in reviewing the source codes of
the standard task flow shipped with Oracle WebCenter Spaces. Today I will show
you how to locate the EAR or WAR file and take the advantages of build-in task
flows.
After the Oracle WebCenter Spaces is installed, go to the
following directory and you will find the relevant EAR and WAR files are
already installed. In my case, it’s WebCenter PS5 but it’s applicable to other
11g releases.
$FMW_HOME/<WebCenter Instance Name>/webcenter/modules/oracle.webcenter.spaces_11.1.1
The one we are interested is the one at the bottom
‘oracle.webcenter.spaces.webapp.war’ file. You can ftp the file from the server
to your local directory and extract it. You will find there are two subfolders
in the file – “META-INF” and “WEB-INF”. If you are familiar with WebCenter/ADF
development/deployment, those two folders should not be strange. The “META-INF”
folder contains configuration files for applications, extensions, class loaders
and services. The “WEB-INF” contains the static content that could be
referenced and defined in some configuration files in META-INF folder for
libraries pre-loading. So there is a folder ‘lib’ residing in WEB-INF and
contains the JAR files that is pre-loaded when the server starts and they are the
libraries that contains the build-in task flows. Here is the snapshot of the
lib directory:
Again,
it contains several JAR files that aggregate different set of resources in
terms of their modules of functionalities and scope of use. We will look at the
one at the bottom “spaces-web” JAR file. In this jar file, you will find all
kinds of build-in task flows that are used internally in standard WebCenter
Spaces resources. For example, in WebCenter Spaces, the default page template
is a template called “Top Navigation”. In the template files, there are several
regions being used are those task flows, which can be found here. Take the
navigation region as an example, you could find the navigation task flow in
this package ‘oracle.webcenter.webcenterapp.view.taskflows.navigation’. Here is
the screenshot of the directory you can find about navigation task flows:
In the same ‘spaces-web’ jar file, you could find:
- All the templates jspx file and their page definition files
- Standard task flows that you can access from resource catalog
- Java Beans that manage/support the transactions for the task flows and page fragments
If you want to learn a certain functionality that how Oracle
WebCenter build or just find out the source codes that behind the scene, you
can find all the relevant info by this means.
