Update web.xml in webcenter portal


Sometimes you need to update the web.xml for webcenter portal if you want to disable compression or add servelets or change the session timeout.

As you know the webcenter potal (AKA Spaces before) is already deployed application .

In order to update the web.xml you need to create extension shared library and add web.xml to it with your updates. here are simple steps to do it:

  1. download webcenter extensions for jdevloper from here
  2. add these extensions to your jdevloper follow this blog
  3. create new application “webcenter portal server extension”
  4. you will find 2 projects “PortalExtension” & “PortalSharedLibrary”
  5. expand PortalSharedLibrary and find the web.xml under WEB-INF
  6. update web.xml as you want
  7. right click on project > project properties > deployment> edit
  8. under web files mark the web.xml to be included in the deployment.
  9. ok then ok
  10. locate the MANIFEST.MF under the project
  11. change the version Implementation-Version & Specification-Version
  12. save
  13. deploy to the server
  14. restart the managed server

Change the webcenter portal language selector task flow to be links instead of popup


The current portal language selector is a popup that shows the available languages to select from .

what if you need to create links or drop down with 2 languages only?!

you can use this code and pass the locale to the parameters

 <af:commandLink styleClass="topNavLinks frlink" rendered="#{facesContext.externalContext.requestLocale eq 'en'}" partialSubmit="false" id="frlink" actionListener="#{o_w_wa_chooseLanguage.changeLanguage}" text="French">
<f:attribute name="wcLangId" value="fr"/>
</af:commandLink>
<af:commandLink styleClass="topNavLinks enlink" rendered="#{facesContext.externalContext.requestLocale eq 'fr'}" partialSubmit="false" id="enlink" actionListener="#{o_w_wa_chooseLanguage.changeLanguage}" text="English">
<f:attribute name="wcLangId" value="en"/>
</af:commandLink>

Content Presenter Taskflow does not render in webcenter Portal Template


My customer asked for new business requirement which to add a js carousel as a banner in the template.

this carousel aim to get images from webcenter content + render some html on it.

while implementing this requirement   it worked great in the edit mode of the template.but it didn’t render at all in view mode on the portal.

I have opened SR with oracle mentioning that the content presenter doesn’t work in templates view mode but it works in edit mode. the reply was content presenter is not designed to work in templates.

but i found a work around that we should not add  content and template in  the taskflow edit wizard itself . Instead we add the content & template  in the content presenter paramters.

where

DataSource: select * from cmis:document

Data Source Type: Query Expression

Template View ID :my_customCS_viewer

Webcenter portal & ADF Responsive


After implementing ADF & portal responsive I have concluded many hints to follow while implementing
The main problem of the responsive it that adf components render as table
1- Limit the use of the components that render tables in the html dom and use html code if needed in verbatim tag
2- Limit the use of layout component that has tables or horizontal layout as it render in tables
Hints
• Preferably use bootstrap templates.
• Create templates with panelgrouplayout vertical & default and create a custom style class to make it to horizontal example ;

.VTOH{
width:100%;
float:left;
margin:0;
padding:0;
} 

• In portal use panel customizable under each other don’t implement it horizontal preferably add it in panelgrouplautout and use the above class & css to draw your page.
• Do the responsive in one CSS file and import it in your template and use media queries inside it.
• All width should in percentage. You may use with for small components on the page but that would be difficult in responsive.
• If you are obliged or have to use component that have fixed width use java script to change the width in responsive.
