use hashmap to simplify commandClass?

[vincent]

Hi, all

I just read a post in this forum, the author created a simple bean which only has a hashmap. The hashmap hold all fields in html form, but I can't get it work.

Here is the command class source:


import java.util.*;

public class hashCommand {

private HashMap formData;

public hashCommand() {

formData=new HashMap();

formData.put("username","");
formData.put("password","");

}

public void setHashMap(HashMap formData) {

this.formData=formData;

}

public HashMap getHashMap() {

return this.formData;

}

}


I have the following configuration for my dispatcher servlet:

<bean name="/signonForm.form" class="signonFormController">
<property name="sessionForm" value="true"/>
<property name="commandClass" value="hashCommand"/>
<property name="formView" value="signonForm"/>
<property name="successView" value="welcome"/>
</bean>

My JSP looks like this:

<spring:bind path="command.formData['username']">
<tr><td>ID:</td><td><input type=text name=username size=15 value="<c:out value="${status.value}"/>"</td></tr>
</spring:bind>


I can't get it work and tomcat complained:

Is there any successfully story? How can I make it work?


Thanks,

Your setter is called getHashMap, not getFormData.

Hi vincent,

you can take the code from my second post in this thread http://forum.springframework.org/showthread.php?t=18687

This was copied and pasted from a working application, so it is running.

Also take a look in the contents of my third post (action-servlet.xml) in the same thread.

As said, everything is working.
