JavaServer Faces:
In General
Sybase Confidential Propriety.
BACKGROUND
 Building high-quality web application user interfaces
is hard
 HTTP request/response model
 HTML dialect(s) and browser capabilities
 Need to support multiple client devices types
Sybase Confidential Propriety.
WHAT IS JAVA SERVER FACES?
 JavaServer Faces (JSF) is a component user interface (UI)
framework for Java web applications.
 It is designed to significantly ease the burden of writing and
maintaining applications that run on a application server and
render their User Interfaces back to a target client.
Sybase Confidential Propriety.
WHY JSF?







MVC (Model-View-Controller) for Web applications
Clean separation of roles
Easy to use
Extensible component and rendering architecture
Support for client device independence
Offers finer-grained separation of behavior and presentation
Component and web-tier concepts without limiting you to a
particular scripting technology or markup language
Sybase Confidential Propriety.
COMPONENT MODEL





Maintaining a reference to model objects
Driving the event-handling
Rendering is separate from the component
JSF implementation provides a set of UI component classes
Standard Component classes, for example
 Commandbutton, Form, Graphic, Input
 Output, Panel, Parameter
 SelectBoolean, SelectMany, SelectOne
Sybase Confidential Propriety.
RENDERING MODEL
 Renderers – Adapt components to a specific markup language
 Encoding – Create markup to represent value
 Decoding – Retrieve request parameters and create new value
 RenderKits – Library of Renders
 Extensible at runtime
 For JSP pages, represented as a custom tag library
 Basic HTML RenderKit part of the standard
Component

Faces technology.
 Visual Development Environment
 Allows building Web pages in a manner very similar to :
 PowerBuilder
 Visual Basic
 A flavor of 4GL experience.
Sybase Confidential Propriety.
OBJECTIVE
 Provides a component model
 Allows users to think about components, events and scripting
instead of the detail of HTTP request / response
 Leverages standards JavaServerFaces runtime
 Uses Java DataStore to make data access easy
 Reuse existing Datawindows in your Web applications
 Make service and EJB invocation in the Web application easy

Sybase Confidential Propriety.
PowerBuilder IDE Integration
• This deployment tool runs on your application
server machine, and emulates the Sybase
EAServer PB NVO deployment API.
• To create a component (in PowerBuilder IDE)
 New -> Target -> EAServer Component, or
 New -> Project -> EAServer Component, or
 New -> Project -> EAServer Component Wizard
• To deploy a component (in project painter)
 “Deploy Button”, or Design -> Deploy Project
• No changes to PowerBuilder IDE are needed!
 Sort of…
Sybase Confidential Propriety.
Installation
• The PB server plugin is installed on the
application server host.
• This does not need to be the same machine
where the PowerBuilder IDE is running.
• The PowerBuilder server VM (or full IDE for
Windows) must also be separately installed on
the application server host.
Sybase Confidential Propriety.
Development – Components
• Develop components as if you were writing
NVOs for deployment to Sybase EAServer.
• Check the PowerBuilder documentation for
general instructions.
• The deployment tool will wrap your PB NVOs as
standard EJB session beans.
 Target-specific deployment descriptors are generated to
automate the binding of JNDI names and JDBC data
source resource references.
Sybase Confidential Propriety.
Development – Data Access
• PowerScript (in NVO source code):
sqlca.dbms = “JDBC”
sqlca.dbparm = “CacheName=’DefaultDS’”
connect;
// check error code
...
// use embedded SQL or DataStore
disconnect; // check error code
• Use your application server’s facilities to define JDBC
data sources and assign JNDI names to them.
• The %PB_SERVER_HOME%/config/pb-server-XXX.xml
can be edited to map PB “cache names” to JNDI names
for JDBC Data Sources. This applies even when using
native drivers.
Sybase Confidential Propriety.
Data Sources – ODBC
• PowerScript (in NVO source code):
sqlca.dbms = ‘ODBC’
sqlca.dbparm=“CacheName=’OdbcDS_JCM’”
...
• When setting up your data source, use:
 JDBC driver class:
 com.sybase.jaguar.jcm.OdbcDriver
 Database URL:
 jcm:TBD;...
• If you need XA (2 phase commit), use JDBC.
• You don’t need to use the cache name OdbcDS_JCM. You can
define custom cache names in config/pb-server-XXX.xml.
Sybase Confidential Propriety.
Development – Data Types
This table shows the
mapping of PB data types
to Java data types that is
applied when an NVO
package is wrapped as an
EJB module.

NVO Class
EJB remote and home interfaces
Array Type
Java array
Structure Type
Java class with public fields
Development – Array Results
• PowerBuilder does not permit methods to directly
return arrays.
• To return an array, embed it inside a PB structure
type.
• PB structure types are mapped to Java classes with
public instance fields.
Sybase Confidential Propriety.
Development - DataStore
• The PB DataStore type, in combination with the
ResultSet return type, is particularly useful for
PB NVOs running in an application server.
• For improved performance, use PB NVO instance
variables and create the DS and assign the
“dataobject” in your NVO constructor.
 But check application server memory usage!
Sybase Confidential Propriety.
PB ErrorLogging Class
• Writes to plugin log file.
 %PB_SERVER_HOME%\logs\pb-server.log
• PowerScript Usage:
ErrorLogging logger
getContextService(“ErrorLogging”, logger)
logger.log(“My Message”)
Sybase Confidential Propriety.
PB TransactionServer Class
• Supported methods:
 CreateInstance, DisableCommit, EnableCommit, IsCallerInRole,
IsTransactionAborted, SetAbort, SetComplete.
• CreateInstance notes (for NVO to NVO inter-component calls):
 Use the two argument form and specify full JNDI name of target
component, e.g. (error checking code omitted for brevity)
TransactionServer ts
getContextService(“TransactionServer”, ts)
pbtest_MyComp comp // remember to generate and use proxies
ts.createInstance(comp, “pbtest/MyComp”)
// call methods on comp
 If the target NVO is not in the same EJB-JAR as the calling NVO, you
might encounter issues with your application server’s class loader (e.g.
ClassCastException). Sybase will NOT support NVO inter-component
calls across EJB-JAR boundaries if you encounter class loader issues.
Consult your application server vendor for assistance with class loader
issues across EJB-JAR boundaries.
Sybase Confidential Propriety.
Development – EJB Clients
• For EJB clients, use your application server’s facilities for
EJB client access.
• If your package is named “MyPackage”, and your
component is named “MyComp”:
 The generated EJB home interface is named
ejb.components.mypackage.MyCompHome
 The generated EJB remote interface is named
ejb.components.mypackage.MyComp
 The Java package for home and remote interfaces can be
overridden. See “Deployment – Java Packages”.
 The JNDI name is “MyPackage/MyComp”.
Sybase Confidential Propriety.
Development – PB Clients
• PowerBuilder has built in facilities for calling
EJBs in third party application servers.
• Check the PowerBuilder documentation for the
EJBConnection class and your application
server documentation for general instructions.
• Alternatively, we provide a proxy server to permit
native IIOP communication (without client-side
JVM) from PB clients to NVOs running in your
EJB server.
Sybase Confidential Propriety.
Web DataWindow
•
Supports browser-based clients using XML, XHTML, HTML.
See DataWindow Programmer's Guide.
 http://sybooks.sybase.com/onlinebooks/group-pb/pbg1000e/dwprgug
•
Note change - to configure (generate and deploy EJB-JAR):
 cd %PB_SERVER_HOME%\bin
 configure web-data-window
•
Note change - to instantiate (from JSF, JSP, servlet etc.):
import com.sybase.pb.datawindow.*;
…
InitialContext nc = new InitialContext();
HtmlGenerator100Home home =
(HtmlGenerator100Home)javax.rmi.PortableRemoteObject.narrow
(nc.lookup(“DataWindow/HTMLGenerator100”),
HTMLGenerator100Home.class);
HTMLGenerator gen = home.create();
Sybase Confidential Propriety.
Deployment – General
• In the PB Project Painter, for your component
project(s), use the “EAServer Host” tab in the
“Project Properties” dialog:




Host name: TCP host name for server machine
Port - 9000
Login ID - admin@system
Login password - (remember, you set it!)
• You can override the host name and port number
that the server uses for its deployment listener
by changing the iiopListeners property in
config/pb-server.xml.
Sybase Confidential Propriety.
Deployment – Web Services
• Not generated by default.
• In the Project Painter Properties dialog, General tab, use
the Comments box to specify which components must be
generated as webServices, e.g.
javaPackage=“...”;webServices=“MyComp1,MyComp2”;
• Remember the semicolon at the end of this entry.
• Your application server must support J2EE 1.4.
• The ResultSet return type is not supported for web
services. Use array and structure types instead.
• Don’t use the WebService tab, or the “wizard” option to
expose a component as a web service. These are only for
Sybase EAServer (with Web Services Toolkit).
Sybase Confidential Propriety.
Deployment – Naming Conventions
• PowerScript identifiers with underscore are mapped to
Java “camel case” for structure fields and NVO methods,
e.g. “my_simple_method” maps to “mySimpleMethod”.
• A leading capital is used for structure types e.g.
“my_structure” maps to “MyStructure”.
• Component names are not changed from what you
specify in the Project Painter. We recommend using the
Java class naming conventions (e.g. “MyComp”).
• Your NVO implementation class can use any name.
Sybase Confidential Propriety.
Deployment – Validation Test
• Using the PowerBuilder IDE, define a component with package
name “pbtest” and component name “MyComp”.
• Add some business methods of your choice. You might want to
try some methods with database access.
• Deploy to your application server.
• Run the following commands:
 cd %PB_SERVER_HOME%
 bin/pb-server-test
• The test program will try to call all methods of your component
with “fake” parameter values (e.g. 1, 2, “S1”, S2”, …)
• If you have a method named “perftest”, the test program will
call it repeatedly to provide basic performance metrics.
• Source code for the test client program can be found in
src/java/com/sybase/pb/server/PbServerTest.java.
Sybase Confidential Propriety.
Remote Debugging
• Use the “Start Remote” button in the
PowerBuilder debugger to start a remote
debugging session, as if debugging a
component in Sybase EAServer.
• Check the PowerBuilder documentation for
detailed instructions.
Sybase Confidential Propriety.
Troubleshooting
• PB application server plugin log:
 %PB_SERVER_HOME%\logs\pb-server.log
• Your application server log file(s).
• Your application server console window (if
applicable).
Sybase Confidential Propriety.
