(三) 配置struts2.0

这里使用Struts2.0。加载5个struts包，调试配置struts action并测试tomcat指向war文件夹，并通过。

- commons-fileupload-1.2.1.jar

- commons-logging-1.0.4.jar

- commons-logging-api-1.1.jar

- freemarker-2.3.13.jar

- ognl-2.6.11.jar

- struts2-core-2.1.6.jar

- xwork-2.1.2.jar

这里不赘述：

把相关配置和程序代码附上：

StrutsTestAction.java

package com.test.struts;

import com.opensymphony.xwork2.ActionSupport;

public class StrutsTestAction extends ActionSupport{

/** serialVersionUID: long 成员描述：TODO */

private static final long serialVersionUID = 1L;

private String username;

@Override

public String execute(){

String username = getUsername();

username += " is just request!";

setUsername(username);

return SUCCESS;

}

/**

* @return the username

public String getUsername() {

return username;

}

/**

* @param username the username to set

public void setUsername(String username) {

this.username = username;

}

teststruts.jsp

<%@ taglib prefix="s" uri="/struts-tags"%>

teststrutstarget.jsp

</html>

测试jsp，通过，代表struts配置完毕。

OK，我们开始尝试让gwt host的调试模式直接访问tomcat。以便能够联通调试前台与后台，否则如果不能联通，那gwt的意义就会大打折扣。
