Custom Look and Feel (CLAF) in Apps 11i (Framework Pages)
This post covers overview of Custom Look and Feel (CLAF) in Self Service Pages (Oracle Apps 11i) and steps to troubleshoot look & feel related issues.
.
Custom Look and Feel functionality in 11i Framework Pages
1.User type in username/password to login to Apps 11i
2. System checks value of profile option Oracle Applications Look and Feel at User Level (if blank then); Responsibility Level (if blank then); Server Level and finally Site Level.
(lets assume value of this profile option is my_claf)
3.Web Server (Jserv component of Apache) then search for page layout template from renderercomponent in $OA_HTML/cabo/lafs/[claf_name].xml (in our case my_claf.xml)
<renderers>
<renderer name=”pageLayout”>
<template name=”pageLayout.uit“></template>
</renderer>
</renderers>
4.System picks page layout from $OA_HTML/cabo/template/[claf_name]/pageLayout.uit(my_claf) and apply to user page
5.System picks style sheet from $OA_HTML/cabo/styles/[claf_name].xss(my_claf.xss) and apply to user page.
.
Terminology / Important files
A. Renderer– renderer defines where items are placed on screen/page and HTML around it.
B. Styles – defines how common components (tabs, buttons) look like.
C. Profile Option – “Oracle Applications Look and Feel“
Value in above profile options determine Look and Feel in Oracle Apps 11i (You can Set profile option at User, Responsibility, Server, Site level)
D. CLAF related directory on Application Tier –
i) Styles– $OA_HTML/cabo/styles
ii) Templates– $OA_HTML/cabo/templates
iii) Cache – $OA_HTML/cabo/styles/cache
– $OA_HTML/cabo/images/cache
iv) Log file related to issues around Look and Feel –
$IAS_ORACLE_HOME/Apache/Jserv/logs/Jserv.log (enable logging in jserv.properties change log=false to log=true)
E. Define new Look & Feel – Responsibility -> Customizing Look and Feel Administrator

Trouble shooting Look and Feel Issues on Framework Pages
Users reported that header (custom GIF – company logo) was missing from OA Framework Pages.
Step 1 – I enabled Extra Logging by updating log=true in jserv.properties
Step 2 – Bounced Apache using adapcctl.sh
Step 3 – Reproduced issue by accessing self service page
Step 4 – Checked logs in jserv.log and found below error
[599] Binding param 2: 1259
[12/06/2008 09:03:09:614 BST] OAPageLayoutBean, localName=’pageLayout’
[12/06/2008 09:03:09:626 BST] null

Steps 5 – Custom GIF (company logo) was urlInclude(relative path like $OA_HTML/companyLogo.gif ) and 11i was configured to use SSL. While searching Oracle Forums found this
Steps 6 – Changed urlInclude to use absolute path (like https://istore.myserver.com/OA_HTML/companyLogo.gif ) ; bounced Apache and this time there was new error message in jserv.log

at HTTPClient.HTTPConnection.setupRequest(HTTPConnection.java:3561)
Step 7 – Added istore.myserver.comin /etc/hosts (Linux Server) file on Web Node, bounce Apache
Step 8 – This time logo was visible
