事前準備工作：
1. Import liferay portal的開發環境到My Eclipse IDE
歩驟：File->Import, Existing projects into Workspace, 指向D:\liferay
2. 把相關會使用到的jar檔，待新的Struts portlet專案建立後逐一included。
ext/modules portal-impl.jar
ext/lib/global portal-kernel.jar
ext/lib/global portal-service.jar
ext/lib/global portlet.jar
ext/lib/global portlet-container.jar
客制Struts Portlet開發：
首先My Eclipse IDE開啟一個”QueryDataPortlet”的Web Project，而後更改web root folder為docroot
接著將游標移至QueryDataPortlet專案點擊滑鼠右鍵，於MyEclipse->Add Struts Capablilities設定Struts組態環境。(記得要取消Install Struts TLDs的選項)
(*記得把Base package for new classes的yourcompany改成XXXcompany)
整理目錄結構，將QueryDataPortlet/src目錄移動到docroot/WEB-INF，如下圖所示：
並且於QueryDataPortlet/docroot中增加css、js、html三個目錄,Copy js/test.js、css/test.css、icon.png到QueryDataPortlet/docroot的js與css等對映目錄。
滑鼠右擊QueryDataPortlet專案，選取Properties->Source項目，按Add Folder重新設定新的Source folder為QueryDataPortlet/docroot/WEB-INF/src，並移除mssing path。
於docroot/WEB-INF內建立liferay的四大設定檔：

使用Ant生成新專案的build.xml與.war檔：
1. 滑鼠右擊QueryDataPortlet專案，選擇Export->Ant Buildfiles項目，於QueryDataPortlet的核取方格上打勾
2. 修改剛才產生的build.xml,加入紅標字體的區塊於檔案中
<target depends="init" name="build-project">
<echo message="${ant.project.name}: ${ant.file}"/>
<javac debug="true" debuglevel="${debuglevel}" destdir="docroot/WEB-INF/classes" source="${source}" target="${target}">
<src path="docroot/WEB-INF/src"/>
<classpath refid="QueryDataPortlet.classpath"/>
</javac>
<jar destfile="${ant.project.name}.war">
<zipfileset dir="docroot/">
<include name="**/*.*" />
<exclude name="**/*.war" />
</zipfileset>
</jar>
</target>
3. 滑鼠右擊上述build.xml，選擇Run As->Ant Build，接著產生QueryDataPortlet.war
Deploy QueryDataPortlet專案，打開 IE8.0輸入http://localhost:8080開啟liferay portal，以Bruno (Admin)管理者帳號登入，選擇Add Application->Sample->”Query Data from DB.” ->add項目，將它附加到liferay portal。
