You have 4 buttons each with the same name "name" and same value "Click". Use that index i to name your buttons and values as well.

Please consult the section on intrinsic events for more information about scripting and events. The following example shows how the contents of a user-specified file may be submitted with a form.
The user is prompted for his or her name and a list of file names whose contents should be submitted with the form. Possible values: submit: Creates a submit button. This is the default value.
The buttons contain images by way of the IMG element. Recall that authors must provide alternate text for an IMG element. Visual user agents are not required to present a SELECT element as a list box; they may use any other mechanism, such as a drop-down menu. This is particularly helpful when the user must choose from a long list of options; groups of related choices are easier to grasp and remember than a single long list of options. In HTML 4. User agents should determine which choices are pre-selected as follows: If no OPTION element has the selected attribute set, no options should be pre-selected.
User agents may vary in how they handle this error, but should not pre-select more than one choice. Implementors are advised that future versions of HTML may extend the grouping mechanism to allow for nested groups i.
This will allow authors to represent a richer hierarchy of choices. When specified, user agents should use the value of this attribute rather than the content of the OPTION element as the option label. When rendering a menu choice , user agents should use the value of the label attribute of the OPTION element as the choice. In this example, we create a menu that allows the user to select which of seven software components to install.
The first and second components are pre-selected but may be deselected by the user. The remaining components are not pre-selected. The size attribute states that the menu should only have 4 rows even though the user may select from among 7 options. The other options should be made available through a scrolling mechanism. Note that where the value attribute is set, it determines the control's initial value , otherwise it's the element's contents. Visual user agents may allow users to select from option groups through a hierarchical menu or some other mechanism that reflects the structure of choices.
A graphical user agent might render this as:. The top label of the menu displays the currently selected value PortMaster 3, 3. The user has unfurled two cascading menus, but has not yet selected the new value PortMaster 2, 3. Users should be able to enter more lines than this, so user agents should provide some means to scroll through the contents of the control when the contents extend beyond the visible area.
Users should be able to enter longer lines than this, so user agents should provide some means to scroll through the contents of the control when the contents extend beyond the visible area. User agents may wrap visible text lines to keep long lines visible without the need for scrolling.
User agents should use the contents of this element as the initial value of the control and should render this text initially. Second line of initial text. This element creates a single-line text input control. See the Transitional DTD for the formal definition. This attribute specifies a prompt string for the input field. User agents may use the value of the prompt attribute as a title for the prompt.
In practice, the input string is restricted to Latin-1 as there is no mechanism for the URI to specify a different character set. For those controls that have implicit labels, user agents should use the value of the value attribute as the label string.
When present, the value of this attribute must be the same as the value of the id attribute of some other control in the same document. When absent, the label being defined is associated with the element's contents. The for attribute associates a label with another control explicitly: the value of the for attribute must be the same as the value of the id attribute of the associated control element.
More than one LABEL may be associated with the same control by creating multiple references via the for attribute. This example creates a table that is used to align two text input controls and their associated labels.
To associate a label with another control implicitly, the control element must be within the contents of the LABEL element. The label itself may be positioned before or after the associated control. In this example, we implicitly associate two labels with two text input controls:. Note that this technique cannot be used when a table is being used for layout, with the label in one cell and its associated control in another cell.
See the section below on access keys for examples. Labels may be rendered by user agents in a number of ways e.
Grouping controls makes it easier for users to understand their purpose while simultaneously facilitating tabbing navigation for visual user agents and speech navigation for speech-oriented user agents. The proper use of this element makes documents more accessible. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams?

You may give them two different names and you check which one has been clicked looking for its name in the parameters request.

In the ProcessButtons servlet, you have the following statement nested within your if statements:. I have tested your html and only one name is passed to the servlet when I press the Submit1 button.
I do not know how the Submit2 parameter could also exist in your request object when the Submit1 button is pressed. I checked the class files are available. Could you let me know why the class is referenced as nil. ButtonTester in web.
