We have developed JSF portlets based on IBM Portlet API. The development is
performed using RAD 6.0.0.1 and locally tested using WPS 5.1 Test Environmen
t. We have designed inhouse JSF components and using it as tags.
These portlets are deployed to PROD environment which has WebSphere Portal 5
.1 with Fix pack 1 full install. The OS is AIX.
In our JSF tags, we are rendering images ( up arrow and down arrow). The pro
perties are passed to JSF tag as below:
<h:column id="priceChangeColumn"
rendered="#{pc_InvestmentVehicleView.priceChangeColumnRendered}">
<RepDesktop:PriceChange
id="priceChange" priceData="#{varlist.priceData}"
upImageName="../../images/SmallUpArrow.gif"
downImageName="../../images/SmallDownArrow.gif"/>
</h:column>
This code fragment works well in various environments from RAD Local Dev, De
velopment AIX, TEST/Quality AIX but fails in PROD AIX with following excepti
on stack trace:

In case of JSF tags, we can procure FacesContext in three different way.
- First is using getFacesContext() call,
- second FacesContext is passed from super class to encodeBegin and encodeEn
d methods and
- third is use static method call : FacesContext().getCurrentInstance().
The JSF Tags are using second method. It would great to know that while deve
loping JSF JSP tag, which method of using FacesContext is a best practice an
d will help us to avoid exceptions we are seeing. Kindly advise.
If this problem is been seen already and if there is any solution to this ex
ception.
Thanks for help in advance.
