Building ADF Jar using maven

2010-11-14T19:20:00.000-08:00

You can build ADF jar using maven.
Steps:
In order to build ADF application using maven you need to add 2 plug-ins to the POM file
1. compiler plugin
2. ant plugin.
Ant plugin is used to run the ojdeploy build xml file.
ojdeploy build xml should have the deployment profile information.

Declarative way to allow an action to set value before navigation

2010-11-14T18:11:00.000-08:00

On Actions like CommandButton, CommandLink,.. you can allow them to set value before navigating to another page by using <af:setActionListener>

Example:
<af:commandLink text="#{row.formattedName}" id="cl1" action="toSavePage">
<af:setActionListener from="phoneNumber" to="#{pageFlowScope.phoneNum}"/>
<af:setActionListener from="#{row.empId}" to="#{pageFlowScope.selectedEmployeeId}"/>
</af:commandLink>

Activating Taskflow in ADF

2010-09-04T12:13:00.000-07:00

Taskflow can be activated by setting the following properties.

activation = conditional
active = EL expression which returns true.

If there are multiple taskflows dropped as regions in the same jsff page as tabs. The page needs to be refreshed for every tab click.

Refresh Taskflow

protected void refreshPage(){
FacesContext fc = FacesContext.getCurrentInstance();
String refreshPage = fc.getViewRoot().getViewId();
ViewHandler ViewH = fc.getApplication().getViewHandler();
UIViewRoot UIV = ViewH.createView(fc,refreshPage);
UIV.setViewId(refreshPage);
fc.setViewRoot(UIV);
}

af:input file configuration in oracle adf

2010-07-15T21:28:00.000-07:00

File upload processing requires the installation of the ADF Faces Filter. This filter is required for all ADF Faces applications. One of its features is handling file uploads. To install the filter, first add the following entry to your WEB-INF/web.xml file:

<filter>

<filter-name>adfFaces</filter-name>

<filter-class>oracle.adf.view.faces.webapp.AdfFacesFilter</filter-class>

</filter>

Second, map that filter to process all FacesServlet requests. For example, if you've named the FacesServlet "faces":

<servlet>

<servlet-name>faces</servlet-name>

<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>

</servlet>

...then use the following filter-mapping:

<filter-mapping>

<filter-name>adfFaces</filter-name>

<servlet-name>faces</servlet-name>

</filter-mapping>

inputFile

To support uploading a file on your page, use the < af:inputFile > component . Like all other input components, < af:inputFile > sends ValueChangeEvents . And like all ADF Faces input components, it has built-in support for accessibility, labels, and messages.

<af:inputFile label="Upload:"

valueChangeListener="#{backingBean.fileUploaded}"/>

< af:inputFile > can be placed in either an < h:form > tag or an < af:form > tag, but in either case you have to set it to support file upload. For the JSF Basic HTML form, that involves setting the "enctype" to the correct magic value; for the ADF Faces form, just set "usesUpload" to true:

<af:form usesUpload="true">

<af:inputFile label="Upload:"

valueChangeListener="#{backingBean.fileUploaded}"/>

</af:form>



<h:form enctype="multipart/form-data">

<af:inputFile label="Upload:"

valueChangeListener="#{backingBean.fileUploaded}"/>

</h:form>

web.xml
<context-param>



<param-name>oracle.adf.view.faces.UPLOAD_MAX_MEMORY</param-name>



<param-value>512000</param-value>

</context-param>

<context-param>



<param-name>oracle.adf.view.faces.UPLOAD_MAX_DISK_SPACE</param-name>

dynamic regions with adf taskflows

2010-07-14T06:19:00.000-07:00

When ADF taskflow dropped as a dynamic region, it prompts for managed bean. Default it creates the manage bean in backing bean scope, according to andrejaus it must be created in pageflow scope.

How to package a project to be a shared library in WebLogic Server

2010-02-09T21:11:00.000-08:00

How to package a project to be a shared library in WebLogic Server

If you are packaging a project and want to deploy it as a shared library in a WebLogic Server, you must wrap the ADF Library JAR with a WAR or EAR file and then install the WAR or EAR as a shared library into the Oracle WebLogic Server.

For design time usage, producers of the ADF library JAR can create a .library file that contains the paths to the ADF Library JAR files. The consuming project can add this Library file to the project's libraries and classpath. When the Library file is created, the Deploy by Default option must be deselected, otherwise the JAR paths in the Library file will be included in the user's deployment, thereby creating a runtime conflict with the same JARs in the shared library.

When the consuming application is being deployed, the dependent ADF Library JAR wrapped inside a WAR or EAR must already have been deployed to the Oracle WebLogic Server as as shared library.

Create an ADF Library JAR file.

Right-click the project and select Project Properties > Libraries and Classpath and add the ADF Library JAR file created in step 1.

Create a WAR deployment profile for the project.

Create the WAR or EAR file. If you do not have ADF Faces components in your project, add the ADF Faces technology scope to your project before you create the WAR or EAR file.

Deploy the WAR or EAR file to the WebLogic Server as a shared library using tools such as the Oracle Fusion Middleware Configuration Wizard, Enterprise Manager, or WLST scripts.

From the main menu, choose Tools > Manage Libraries.

In the Manage Libraries dialog, click Load Dir.

In the Load Directory dialog, select the directory where you want to place the Library files. This folder should be in a location next to the corresponding folder of ADF Library JAR files to simplify the process of locating files. It can even be the same folder.

In the Manage Libraries dialog, click New.

In the Create Library dialog, enter a library name and click Add Entry.

In the Select Path Entry dialog, select the libraries you want to add and click Select.

In the Create Library dialog, be sure that Deployed by Default is not selected, click OK and click OK again.

Open the Library file you created in Step 10 in a text editor and set the locked property to true and save the file.

At design time, any consuming project can reference this shared library by adding the Library file to the project using the Project Properties window.

In the Application Navigator of the consuming project, from the main menu, choose Tools > Manage Libraries.

In the Manage Libraries dialog, click Load Dir.

In the Load Directory dialog, select the directory where the Library files were created in Step 7.

In the Application Navigator of the consuming project, right-click a project and select Project Properties.

In the Project Properties window, select Libraries and Classpath and click Add Library.

In the Add Library dialog, select the Library file and click OK.

click OK.

You must edit either the WEB-INF/weblogic.xml for a WAR or the META-INF/weblogic-application.xml for an EAR to include a library-ref entry that specifies the name and version of the shared library that was produced in Step 4.

Post-deployment application configuration using ADF MBeans

If you plan to configure ADF connection information or adf-config.xml using ADF MBeans after the application has been deployed, make sure that the application is configured with MDS. The adf-config.xml file must include MDS entries, as shown in the following example. If it does not, edit the file to include them.

<adf-mds-config xmlns="http://xmlns.oracle.com/adf/mds/config">

<mds-config xmlns="http://xmlns.oracle.com/mds/config"

version="11.1.1.000">

<persistence-config>

<metadata-store-usages>

<metadata-store-usage default-cust-store="true"

deploy-target="true" id="myRepos">

</metadata-store-usage>

</metadata-store-usages>

</persistence-config>

</mds-config>

</adf-mds-config>

The web.xml file must also contain entries for each ADF MBean. The following example shows entries for three ADF MBeans.

<listener>

<listener-class>oracle.adf.mbean.share.connection.ADFConnectionLifeCycleCallBack

</listener-class>

</listener>

<listener>

<listener-class>oracle.adf.mbean.share.config.ADFConfigRuntimeLifeCycleCallBack

</listener-class>

</listener>

<listener>

<listener-class>oracle.bc4j.mbean.BC4JConfigLifeCycleCallBack

</listener-class>

</listener>

Weblogic Deployment Plan

2010-01-30T21:18:00.000-08:00

In weblogic for an application a plan can be setup using plan.xml

How to create plan.xml
1. Open application that was deployed using weblogic console
2. Open configuration tab and make changes. Any changes made to configuration of the application will create plan.xml.
3. It will prompt the location of the Plan.xml.

How does it look like and how does it work ?
Here is a sample of a plan.xml :
<?xml version='1.0' encoding='UTF-8'?>
<deployment-plan xmlns="http://xmlns.oracle.com/weblogic/deployment-plan" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.oracle.com/weblogic/deployment-plan http://xmlns.oracle.com/weblogic/deployment-plan/1.0/deployment-plan.xsd">
<application-name>app</application-name>

<module-type>ear</module-type>

<module-descriptor external="false">

<uri>META-INF/weblogic-application.xml</uri>

<variable-assignment>

<name>SessionDescriptor_invalidationIntervalSecs_12648285993120</name>

<xpath>/weblogic-application/session-descriptor/invalidation-interval-secs</xpath>

</variable-assignment>

</module-descriptor>

<module-descriptor external="false">

<uri>META-INF/application.xml</uri>

</module-descriptor>

<module-descriptor external="true">

<root-element>wldf-resource</root-element>

<uri>META-INF/weblogic-diagnostics.xml</uri>

</module-descriptor>

</module-override>

<module-override>

</module-override>

<config-root>C:\TGDev\Products\Oracle\Middleware\user_projects\domains\OWCS_domain\servers\AdminServer\upload\TestWeblogicPlan_application1</config-root>

</deployment-plan>

As you can see XPath is used to qualify the path of the attribute to update. For instance, here it's "/weblogic-web-app/session-descriptor/timeout-secs".

You will notice that the XPath indicated is simply the path to that attribute in the following weblogic.xml deployment descriptor.

The changes in Plan.xml will take effect only after update of the application and restart of the domain.

Note: specify your changes in the overide tag of plan.xml. With the plan.xml you can set values to weblogic.xml and weblogic-application.xml

11g virtual dir url pattern is not identified correctly

<virtual-directory-mapping>

<local-path>x:/test/vdir</local-path>

<url-pattern>/test/*</url-pattern>

</virtual-directory-mapping>

Solution
1. Create directory name test and put ur file in that directory

The directory should be created at this path x:/test/vdir. But do not specify the test directory in your local-path.

<virtual-directory-mapping>

<local-path>x:/test/vdir</local-path>

<url-pattern>/test/*</url-pattern>

Adding libs to ear

2009-12-17T19:07:00.001-08:00

Many users have problems to use their libraries in theirapplications. But sometimes a working solution is too obvious to benoticed.
To include all the libraries you need for your project in an EAR file:

Create a package project called common-libs and put all the libraries in a directory included in the Project Source Path. Don't use the src directory but lib at the same hierarchy level. Add this new directory to the Project Source Paths.
Open the Application Properties
Create a deployment profile for the EAR file.
To include the libraries within the EAR file we have two options to include the libraries are available: either put into APP-INF/lib or a directory of your choice (eg. lib). In the Deployment Profile select Application Assembly, tick the check box of every JAR file you need and enter the directory name (APP-INF/lib or lib) in the Path in EAR text field at the bottom. This must be done for every JAR file!
If you do not want to use APP_INF/lib you need to create an application.xml for the application. Open the Application Resources accordion and expand Descriptors and META-INF to see which Deployment Descriptors are available. On Descriptors, chose New JEE Deployment Descriptor... from the Context Menu and select application.xml. In the newly created application.xml insert the tag <library-directory>lib</library-directory>.
From the Application Menu select Deploy to EAR File to check the contents before deploying it to the server.
