Detect the browser type and version in ADF

How-to detect the browser type and version


The Trinidad RequestContext object provides access to the user browser type and browser version. using Expression Language as

#{requestContext.agent.agentName}

#{requestContext.agent.agentVersion}

Trinidad RequestContext class is exposed through the AdfFacesContext class, which means that we can also use

#{adfFacesContext.agent.agentName}

#{adfFacesContext.agent.agentVersion}

OAF setup on server before running Oracle Self-Service Web Applications

Configure environment variables and servlet zone list, these are prerequisite before deploying the OAF code on to the server.  (Courtesy : Oracle Documentation)

1. Locate the file jserv.properties.
All environment variables are set in this file. It is important to get $CLASSPATH and $LD_LIBRARY_PATH correct here. You can look at APPLSYS.env and adovars.env under $APPL_TOP for these two variable settings.

2. In jserv.properties, modify the following parameters:
wrapper.bin
The wrapper.bin property must contain the full path to the executable for the Java Virtual Machine. It sets which Java Virtual Machine interpreter to use here. For example:
wrapper.bin=/local/java/jdk1.1.6/bin/java

wrapper.classpath
This property contains the CLASSPATH environment value passed to the JVM. The wrapper.classpath property must contain both the JSDK and the JServ jar file. It should probably also contain the JVM's classes.zip file and directives of servlet zones.
The syntax is:
wrapper.classpath=[path]
For example:
wrapper.classpath=/usr/local/ApacheJServ/jservlets
wrapper.classpath=/local/java/jdk1.1.6/lib/classes.zip
wrapper.classpath=/usr/local/ApacheJserv/src/java/ApacheJServ.jar

wrapper.env
This property is an environment name whose value is passed to the JVM.
The syntax is:
wrapper.env=[name]=[value]

You should set the $LD_LIBRARY_PATH variable here to the directory which contains the JDBC library file. For example:
wrapper.env=LD_LIBRARY_PATH=/oracle/db/8.1.6.1/lib

NLS environment variables should also be set here for the JDBC to operate. For example:
wrapper.env=NLS_LANG=AMERICAN_AMERICA
wrapper.env=ORA_NLS33=/opt/tools/ocommon/nls/admin/data
wrapper.env=NLS_DATE_FORMAT=DD-MON-RR

zones
This property lists the servlet zones that JServ manages. The syntax is:
zones=,
For example:
zones=jservlets

You must specify the configuration file location for each servlet zone that is specified. For example:
jservlets.properties=/usr/local/ApacheJServ/jservlets/

Find the ADF component from the page source.

When the JSF page becomes bulkier, the HTML view source of JSF pages is not very easily readable.
Setting the below flag in trinidad-config.xml ( under view controller -> Web Content -> WEB-INF) will add comments showing which ADF component caused which HTML to be rendered.


<debug-output>true </debug-output>


Found it very handy and useful.
