Cannot find ActionMappings or ActionFormBeans collection , when he access the login.jsp of the application deployed in WebSphere Application Server (WAS) running on the Linux server. The application was developed using the framework struts 1.2 and the application works fine with ide WSAD. The above error is thrown when the application server executes the following line
<html:form name="loginForm" type="Sales.login.LoginForm" method="post" scope="request" action="/login.do" onsubmit="return submitForm()" >
The above error may occur due to various reasons.
Some of the situations where the error may be thrown are as follows
Situation 1 : When the Request Processor searches for the mapping of this request, if it is not able to find the mappings that are defined in the struts-config.xml , the following errors may be thrown depending upon the situation.
a) If the server is able to load the struts-config.xml , but the mapping is not available in the struts-config.xml . for eg. if the JSP has <html:form action="/login" method="post" type="LoginAction">
then your struts-config.xml should have mapping for action parameter i.e. "/login" something like
<action-mappings>
<action path="/login" type="LoginAction" name="loginForm" scope="request" validate="false" input="/login.jsp" >
</action>
</action-mappings>
But if the mapping is not present in the struts-config.xml , then you may get the error [Cannot retrieve mapping for action /login1]: javax.servlet.jsp.JspException: Cannot retrieve mapping for action /login
b) But the above mapping is present in the struts-config.xml , but you are getting the error Cannot find ActionMappings or ActionFormBeans collection , That means the sever is not able to load the struts-config.xml fle.
To solve , the above problem , Please ensure , the path & file name of struts-config.xml file mentioned in the web.xml file is correct and case sensitive.
In our case , the problem was very silly and the problem got solved when i add a slash (/) infront of WEB-INF ...
The belows lines are part of the web.xml and the param-value to be passed to ActionServlet is wrongly mentioned
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
<init-param>
<param-name>config</param-name>
<param-value>WEB-INF/struts-config.xml</param-value> OR <param-value>/web-inf/struts-config.xml</param-value> // Wrong
</init-param>
In the above lines , changing the line <param-value>WEB-INF/struts-config.xml</param-value> OR <param-value>web-inf/struts-config.xml</param-value> to
<param-value>/WEB-INF/struts-config.xml</param-value> , will solve the problem
Situation 2 : If the sever is able to load the struts-config.xml fle and also the mapping is present in the struts-config.xml , then the Request Processor does process any ActionForm bean related to this request. (i.e. finding , loading the ActionFormBeans collection, ..etc ) .
Various classes such as org.apache.struts.action.ActionFormBeans , org.apache.commons.collections.FastHashMap are involved for the above process. And the following jars are involved
struts.ear
commons-collections.jar
commons-beanutils.jar
....
.....
So If you miss the jar files such as commons-collections.jar , commons-beanutils.jar in the class path , then the request processor may not find the ActionFormBeans collection , and the error Cannot find ActionMappings or ActionFormBeans collection is thrown
<html:form name="loginForm" type="Sales.login.LoginForm" method="post" scope="request" action="/login.do" onsubmit="return submitForm()" >
