background
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
what is java server faces
WHAT IS JAVA SERVER FACES?
  • JavaServer Faces (JSF) is a component userinterface(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.
why jsf
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
component model
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
rendering model
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

  • WebLogic 8.1 (9.0 at GA)
  • WebSphere 6.0
  • Post-1.0
    • Geronimo 1.0
    • Oracle 10 (OC4J)
  • Others may work, but are not tested by Sybase and configuration instructions may vary from what we document.
supported operating systems
Supported Operating Systems
  • Development environment
    • Windows
  • Server runtime environment - same as the supported platforms for PBVM with Sybase EAServer.
    • Windows
    • Solaris
    • AIX
    • HP/UX
powerbuilder ide integration
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…
installation
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.
development components
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.
development data access
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.
data sources odbc
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.
development data types
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.
development array results
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.
development datastore
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!
pb errorlogging class
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”)

pb transactionserver class
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.
development ejb clients
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”.
development pb clients
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.
web datawindow
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();

deployment general
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 - [email protected]
    • 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.
deployment web services
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).
deployment naming conventions
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.
deployment validation test
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.
remote debugging
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.
troubleshooting
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).
