Seam 2.0 without JSF , RHDS release

Seam2.0之後,將把"JSF限定"拿掉,目前計畫整合ZK(zkseam.demo)和Wicket.

ZK是非常優秀的Ajax Framework,可以帶給用戶非常棒的AJAX體驗,但是架構上比起JSF還是不足,這要等待日後seam對其整合的如何.

Wicket的想法很棒,徹底把元件從網頁中拿掉,讓網頁設計師輕鬆許多,省了許多溝通上的麻煩,但是把網頁的TAG放到後端重組成自己的TAG,花費了許多額外的效率,這一點還沒上線過比較大專案,所以還不確定影響到什麼地步,改天找個案子來試試看.

期待很久的Red Hat Developer Studio終於發佈了,整合了JBossIDE和ExadelIDE並且加入Seam,可以說是JBoss最強的武器吧XD,想挑戰Rails的開發速度嗎?Try it!Seam-gen will make it come true!

Configure Richfaces3.1 with Seam2.0

英文寫的不好,看不懂請包涵XD.
Required : richfaces-ui-3.1.0-rcX-bin and jboss-seam-2.0.0.BETA1

1. lib
   (1)Delete ajax4jsf-1.1.1.jar and richfaces.jar from jboss-seam-2.0.0.BETA1\lib.
   (2)Put richfaces-api-3.1.0-rcX,richfaces-impl-3.1.0-rcX,richfaces-ui-3.1.0-rcX into jboss-seam-2.0.0.BETA1\lib.
2. modify jboss-seam-2.0.0.BETA1\build.xml
   (1)Delete all ajax4jsf*.jar from build.xml.
   (2)Find description="extra jars for the EAR" in build.xml
   ,delete include name="el-*.jar" and insert include name="richfaces-api*.jar"
3. web.xml
   Ajax4jsf filter not needed, Seam Filter installs it for us.
   You can reference "booking" example.
4. view/pages.xhtml
   Let's modify booking\view\home.xhtml.
   Add xmlns:rich="http://richfaces.ajax4jsf.org/rich" in html tag.
   Try rich:panel on booking\view\home.xhtml.
   Finally, build it ,you will see beauty richfaces.

最近JSF元件的發展

• 眾所期待的myfaces core終於支援JSF1.2,不過Tomahawk目前尚未支援JSF1.2.
• icefaces 1.6.0(final) release,正式支援第三方的元件Tomahawk,看來richfaces很有可能被取代掉.
• WebGalileo Faces也加入open source的陣營,比icefaces更多元件,尚未支援JSF1.2,對Opera的支援有點差

目前客製化JSF的元件還是相當困難,如果可以做一套符合標準的TOOL來設計元件該有多好

Seam make JSF like Rails

很久沒更新BLOG了,最近忙著處理兵役的瑣事,還有找公司收留我XD,
來聊聊最近我開始玩的Seam,如果厭倦了瑣碎的XML設定方式,
Seam使用了許多優秀的annotations會讓妳感動到痛哭流涕,
並且簡化jBPM的使用方式,還有Seam-gen讓妳開發像Rails一樣快速,
presentation tier 使用icefaces,Richfaces,Myfaces和Seam Tags,最近Seam2.0 beta加入GWT,
persistence tier預設使用EJB3(許多人對EJB有很深的怨念XD),
請放心可以轉換成Hibernate,Seam是目前我看到最優秀的Framework,雖然還有許多BUG,但出身名家,不用擔心停產XD.目前玩的Seam2.0 beta有許多BUG尚未解決,期待Production版早點release讓我玩

Connect DB by ODBC on Rails

1. Install
   rails 1.2 gem install -v=1.4 odbc-rails
   rails 1.1 gem install -v=1.3 odbc-rails


2. Enabling Loading of the Adapter
   -> root\lib\ruby\gems\1.8\gems\activerecord-1.14.4\lib\active_record
        RAILS_CONNECTION_ADAPTERS = %w( mysql postgresql ... openbase odbc)


3. Set up your Ap
   your ap -> config/environment.rb
                        require File.join(File.dirname(__FILE__), 'boot')
                        require 'odbc_adapter'
   -> config/database.yml
                        development:
                        adapter: odbc
                        dsn: 使用者資料來源名稱

[ICEfaces]支援myafecsTomahawk元件

1.myfaces lib
myfaces-core 1.1.5 & tomahawk v1.1.5

2.icefaces lib
ICEfaces-1.6.0-DR4

3.RI implementation會跟myfaces起衝突,把jsf-api.jar和jsf-impl.jar拿出

4.web.xml設定

(1)加入servlet
   servlet
           servlet-name Main Dispatch Servlet servlet-name
          servlet-class com.icesoft.faces.webapp.http.servlet.MainServlet servlet-class
          load-on-startup 1 load-on-startup
   servlet

   servlet-mapping
           servlet-name Main Dispatch Servlet servlet-name
           url-pattern *.iface url-pattern
   servlet-mapping

(2)將FacesServlet和ExtensionsFilter所mapping的去除,
否則會造成myfaces和icefaces之間無法cast的錯誤

(3)加入context-param
context-param
   param-name
          com.icesoft.faces.standardRequestScope
   param-name
   param-value
          true
   param-value
context-param

(4)加入listener
listener
    listener-class
           com.icesoft.faces.webapp.http.servlet.SessionDispatcher$Listener
    listener-class
listener

5.faces-config.xml設定
若有使用facelets,將view-handler改成com.icesoft.faces.facelets.D2DFaceletViewHandler
取代com.sun.facelets.FaceletViewHandler
