Display SWF file in Webcenter Space

There may be a requirement to display SWF inside Oracle Webcenter Space. The SWF file can be added to space as content presenter in following way.

All we need to do is to embed our SWF file inside HTML file. Following is the code that can be used:

<html>
<body>
<object width="500" height="500">
<param name="movie" value="http://localhost:16200/cs/groups/public/documents/document/newswf.swf">
<embed src="http://localhost:16200/cs/groups/public/documents/document/newswf.swf" width="400" height="400">
</embed>
</object>
</body>
</html>

The SWF file in above code is coming from UCM. Once done, the HTML file can be easily added to Webcenter Space as content presenter. The same concept can also be used for some video files.

Store TaskFlow Input Param in Memory Scope or Managed Bean?

If we need to specify some input parameters for our Bounded task flow then, we can specify value (Note: the value field in Input parameter definition indicates the location where the input parameter will be stored. It does not indicate the value of the parameter we are defining.) either using managed bean or in memory scope. The recommended way is to use managed bean or a simple pojo class configured as manged bean in a memory scope. The reason of using managed bean is that we can use comments in our class file to indicate the purpose for other developers and also make it clear what exactly the input parameters are and where they are stored as they can now be access using managed bean.

Disable text filed in InputDate Component @ADF

If you need to disable the input text filed for adf:inputDate component then we can do that using any of the java scripts below.

1) This script will disable the key events on the text filed. Thus the user will not be able to edit the selected date using Keyboard.

<af:resource>
function disableEntry(evt){
evt.cancel();
}
</af:resource>

<af:inputDate label="Label 1" id="id1" readOnly="false"
contentStyle="background-color:lightgray;">
<af:clientListener method="disableEntry" type="keyDown"/> </af:inputDate>

2) This script will completely disable the text filed. The only problem with this script is that, if we have many input date components on a page, then we will need to apply this for all component by their IDs.

<af:document id="d1">
<f:facet name="metaContainer">
<f:verbatim>
<script type="text/javascript">
function disable(evt) {
document.getElementById('id1::content').disabled=true;
}

</script>
</f:verbatim>
</f:facet>
<af:clientListener method="disable()" type="load"/>
.....
<af:inputDate label="Date Picker" value="#{pageFlowScope.genPDF.dateEcheance}" binding="#{pageFlowScope.genPDF.id1}" id="id1"/>

Bounded Task Flow as ADF Library @ADF

To know how to deploy BTF as ADF library, please refer to this tutorial.

I created two different project, one producer that was deployed as ADF library and one consumer for deployed task flow, with all the default settings. Everything was smooth until running the consumer. While running i got following error:

oracle.jbo.JboException: JBO-34010: The "view/DataBindings.cpx" descriptor appears in the application classpath more than once:
jar:file://.../JDeveloper/system11.1.1.4.37.59.23/DefaultDomain/servers/DefaultServer/tmp/_WL_user/ApplicationPack_V2.0/63ryyw/war/WEB-INF/lib/BTFADFLibrary.jar!/view/DataBindings.cpx

file://.../JDeveloper/system11.1.1.4.37.59.23/o.j2ee/drs/ApplicationPack/ApplicationPackWebApp.war/WEB-INF/classes/view/DataBindings.cpx

The reason was same name of the packages in both the projects. The Databinding.cpx file was under view package in both project. Tried to change the package name from project properties -> project source path -> Default Package option but still received the same error. I recreated the producer project with new package names and the error was resolved. Other way will be to use refactoring.

Admin Applets not working @Content Server

I installed content server 11.1.1.3 on windows7 32 bit. The admin applets were working fine just after installation. But later i re-installed oracle database, created new schemas with rcu 11.1.1.4, and updated java version to 1.6.0_21 from 1.6.0_18. Now the admin applets are not working. :-\

Now, whats the reason for this????

Here it is: It was as simple as it should have been. The browser (IE) was having java 1.6.0_26 ad-on. But it was not working. So i ran the application on mozilla and installed java 1.6.0_26 plugin and the applets started working. Surprise was, now the applets were working on IE as well :).

So problem was only because of java version used by the browser.
