Getting jasper Exception

From Java Class set the value in the bellow map ans set it within request.

Map<String,String> responseMap = new LinkedHashMap<String, String>();
responseMap.put("requestId", "test");
request.setAttribute("nomineeResponseMap", responseMap);

Now I am trying to get this request from the jsp page but unable to get data from this Map.

Below code which I used in JSP page.

From JSP Page:

Object responseMap = request.getAttribute("nomineeResponseMap");
  if(responseMap instanceof LinkedHashMap) {
    Map<String, String> newMap = (LinkedHashMap) responseMap;
    System.out.println("yesss");
}

Below Exception I am getting while running the program:

org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: 36 in the jsp file: /form/EDCPRequestSuccess.jsp
Generated servlet error:
The type Map is not generic; it cannot be parameterized with arguments <String, String>

An error occurred at line: 36 in the jsp file: /form/EDCPRequestSuccess.jsp
Generated servlet error:
Syntax error, parameterized types are only available if source level is 5.0

Why I am getting the above exception?

If your server is running using JDK 1.5 or higher version. The issue is caused by wrong JSP compiler setting.
For Tomcat server, the setting could be found in $TOMCAT_HOME/conf/web.xml. The error is throwed if compilerSourceVM and compilerTargetVM are set to 1.4 or lower version.

<servlet>
    <servlet-name>jsp</servlet-name>
    <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
    <init-param>
        <param-name>compilerSourceVM</param-name>
        <param-value>1.4</param-value>
    </init-param>
    <init-param>
        <param-name>compilerTargetVM</param-name>
        <param-value>1.4</param-value>
    </init-param>
    <load-on-startup>3</load-on-startup>
</servlet>

Please check your JFK version, I think you are using less than jdk1.5
