1.找到strtus1.1 中的这个文件(struts-example.war)将它解包。(要用到里面的很多文件)
2.在jb下安装struts1.1(jb9里的配置方法,可以参考一下)
Struts1.1比Struts1.0功能增强了很多。比如:提供DynaActionForms,可不用编写任何代码创建动态的ActionForm;多应用支持答应定义多个struts-config.xml配置文件等等。但JBuilder 9只直接支持Struts1.0,不直接支持Struts1.1,下面让我们来看看怎样让JBuilder 9支持Struts1.1。
首先下载 jakarta-struts-1.1,把整个目录放到/extras目录下.
接着在JBuilder用 Configure Libraries对话框 (Tools-->Configure Libraries)创建一个新的library ,我们命名为Struts1.1,把jakarta-struts-1.1lib目录下所有的jar添加到新的library里,在library Settings里设置Framework为Struts,点OK,设置完成.
接下来看看设置是否成功:
File-->New创建一个web application, 在Web Application wizard的jsp/Servlet frameworks中我们看到了Struts 1.1选择框,设置成功!
接下来您就可以在JBuilder9里使用Struts1.1开发您的Web Application了.
3.配置struts-config.xml文件 (文件如下:)
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd";>
<struts-config>
<form-beans>
<form-bean name="testForm" type="test.testForm" />
</form-beans>
<action-mappings>
<action name="testForm" type="test.testAction" validate="true" scope="request" path="/testAction">
<forward name="test" path="/test.jsp" />
</action>
</action-mappings>
<message-resources parameter="test.ApplicationResources" />
<plug-in className="org.apache.struts.validator.ValidatorPlugIn">
<set-property value="/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml" property="pathnames" />
</plug-in>
</struts-config>
3.建立 testForm.java 继续ValidateForm
package test;
import org.apache.struts.validator.*;
import org.apache.struts.action.*;
import javax.servlet.http.*;
public class testForm extends ValidatorForm {
PRivate String testText;
public void setTestText(String testText) { this.testText = testText; }
public String getTestText() { return testText; }
public ActionErrors validate(ActionMapping actionMapping, HttpServletRequest httpServletRequest) { return null; }
public void reset(ActionMapping actionMapping, HttpServletRequest httpServletRequest) {
testText = null;
}
}
4.建立 test.jsp
<%@ page contentType="text/Html; charset=GBK" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<%@ taglib uri="/WEB-INF/struts-template.tld" prefix="template" %>
<html:html>
<head> <title> test </title> </head>
<body bgcolor="#ffffff">
<html:form action="/testAction" >
testText <html:text property="testText"/>
</html:form>
<html:javascript formName="testForm"
dynamicJavascript="true"
staticjavascript="false"/>
<script language="javascript1.1" src="staticjavascript.jsp"></script>
</body>
</html:html>
5.建立 testAction.java
package test;
import org.apache.struts.action.*;
import javax.servlet.http.*;
public class testAction extends Action {
public ActionForward perform(ActionMapping mapping, ActionForm actionForm, HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) {
return mapping.findForward("test");
}
}
6.Copy 文件:
validation.xml,
validation-rule.xml,
ApplicationResources.properties,
staticjavascript.jsp
7.编缉validate.xml文件(不完整,只要一个Form)
<form name="testForm">
<field property="testText"
depends="required, minlength,maxlength">
<arg0 key="prompt.username"/>
<arg1 key="${var:minlength}" name="minlength"
resource="false"/>
<arg2 key="${var:maxlength}" name="maxlength"
resource="false"/>
<var>
<var-name>maxlength</var-name>
<var-value>16</var-value>
</var>
<var>
<var-name>minlength</var-name>
<var-value>3</var-value>
</var>
</field>
</form>
