In Struts 2, we can decide next action to be executed at runtime with complete set of its own\u00a0interceptors. \u00a0here i will assume the example and source code of the previous article.<\/a><\/p>\n

For this demo, change the existing Action class code:
\n<\/p>\n

\npackage com.G2.Actions;\n\nimport com.G2.Model.LoginValidate;\nimport com.opensymphony.xwork2.ActionSupport;\n\npublic class LoginAction extends ActionSupport {\n\n\tString uName,pwd;\n\tString nextAction;\n\n\t@Override\n\tpublic String execute() throws Exception {\n\t\tboolean res = LoginValidate.isLoginValid(uName, pwd);\n\n\t\tif(res)\n\t\t\tnextAction = "LoginSuccess";\n\t\telse\n\t\t\tnextAction = "LoginInput";\n\n\t\treturn  "next";\n\t}\n\n\tpublic String getNextAction() {\n\t\treturn nextAction;\n\t}\n\n\tpublic void setNextAction(String nextAction) {\n\t\tthis.nextAction = nextAction;\n\t}\n\n\tpublic String getuName() {\n\t\treturn uName;\n\t}\n\n\tpublic void setuName(String uName) {\n\t\tthis.uName = uName;\n\t}\n\n\tpublic String getPwd() {\n\t\treturn pwd;\n\t}\n\n\tpublic void setPwd(String pwd) {\n\t\tthis.pwd = pwd;\n\t}\n}\n<\/pre>\n
As you can see, I have added one more filed with setters and getters named “nextAction”\u009d, which will be accessed in struts configuration file.<\/p>\n
Change in Configuration file :<\/p>\n
\n<?xml version="1.0" encoding="UTF-8" ?>\n<!DOCTYPE struts PUBLIC\n        "-\/\/Apache Software Foundation\/\/DTD Struts Configuration 2.0\/\/EN"\n        "http:\/\/struts.apache.org\/dtds\/struts-2.0.dtd">\n\n<struts>\n\n\t<package name="Login" extends="struts-default">\n\t\t<action name="LoginInput">\n\t\t\t<result>\/pages\/Login.jsp<\/result>\n\t\t<\/action>\n\n\t\t<action name="LoginSuccess">\n\t\t\t<result >\/pages\/LoginSuccess.jsp<\/result>\n\t\t<\/action>\n\n\t\t<action name="LoginAction" class="com.G2.Actions.LoginAction">\n\t\t\t<result name="next" type="redirectAction">${nextAction}<\/result>\n\t\t<\/action>\n\n\t<\/package>\n<\/struts>\n\n\n<\/pre>\n
Here we are redirecting, on the next action if the result name is “next”\u009d. The next action is decided by the variable “nextAction” of the Action class. In above configuration if we change the result type to “chain”\u009d instead of “redirectAction”\u009d, then still application will run.<\/p>\n","protected":false},"excerpt":{"rendered":"
