The html:image tag looks OK to me. Since what you've posted is clearly a fragment of the page, it's possible that some other tag on the page other than this one is causing the problem. The exception you're getting usually occurs when you have non-String properties in your ActionForm. Check your ActionForm for non-String types and change them to String.

i am only string variable ?

I'd suggest changing the name of the submit property to something else. I've seen strange things happen because the name "submit" is a javaScript property of a form, and overwriting that name can cause odd behavior.

I'd also try removing the value attribute from your html:image tag and changing the type of the botton's property in your ActionForm to org.apache.struts.util.ImageButtonBean. This is a class that was specifically written to go along with the html:image tag. It has an "isSelected" method you can use to determine if it's been pressed or not. You should also have a different ActionForm property for each button, such as deleteButton, updateButton, insertButton, etc.

You can't have an html:image button and an html:submit button both use the same property. Two submit buttons can share the same property name, but not a submit button and an html:image button. I believe that's what's causing the exception. I'd also suggest you take the advice I gave you in my last post and remove the value attribute from your html:image button. This type of button simply does not work the same as an html:submit button. It must have it's own property, and that property shold be of type ImageButtonBean.

thanks but there is problem

how to know which image is selected

please tell me

As I mentioned in a previous post, the ImageButtonBean has an isSelected method that will return true if the button was selected and false if it was not.

sorry to you i can't understand what to check image is selected

please check my code and tell what is error in this

This is my code in jsp
<html:form action="userManage.do" method="post">
<html:hidden property="accountId" value="${uList.accountId}"/>
<td valign="middle">

<html:image src="include/images/b_drop.png" property="img" alt="Delete Account"/>
</td>

<c:choose>
<c:when test="${uList.status == '0'}">
<td valign="middle"><html:submit property="sub" value=" Enable"/></td>
</c:when>
<c:when test="${uList.status == '1'}">
<td valign="middle"><html:submit property="sub" value="Disable"/></td>
</c:when>
</c:choose>

//

In Action class, change:

To

and change

to

Then, in UserManageBean, change the type of img from String to ImageButtonBean and adjust getters and setters for this change.

i change my according to your instruction but still same error i write my code

this is jsp code

<html:form action="userManage.do" method="post">
<html:hidden property="accountId" value="${uList.accountId}"/>
<td valign="middle">

When you say "same error", do you mean:

java.lang.IllegalArgumentException: No bean specified

? If not, give us the exact error message you're getting. I don't see anything in the code you've shown me that would throw this exception. Are you showing us the entire JSP? I still think there may be something totally unrelated to the code you've posted that may be causing the error.

this jsp page has many forms (4-5) and this page is also include in other jsp page which is main page

problem is same as first

Let me know when you get an error
1) While rendering the JSP page
2) Or after submitting the page

Try to remove your html:image tag for time being, then see what happen

when i click the image button then error receive otherwise no error

when i remove html:image there is no error
