I am doing on Java Struts 2 framework. 

Normally, I can get data from my JSP through the get set method in `Form.java` (action class). Below is my example :

In `main.jsp` file:

```
<html:text property="campaignName" size="50" maxlength="50" />

```

thus, I can get this text box name by get set method in the action class, the below is code from 

**`mainForm.java` :**

```
private String campaignName = null;

public String getCampaignName() {
    return campaignName;
}

public void setCampaignName(String campaignName) {
    this.campaignName = campaignName;
} 

```

However, because of I want to use jQuery to do something, I no longer use `<html:text>` as text box, but I use `<input type="text" id="datepicker" />`.

Because of without property attribute inside this text box, I cant get the value from this text box. I have tried to add `property="something"` inside the text box also, but get set method in `mainForm.java` is return `null`.

I would like to ask, how can I get the value by this text box?
