goal: I want to submit an array of Fonbean(java class file listed below) to an action
strategy: I decide to use html:form and logic:iterate to do this
1.what I have in my configruation xml
<form-beans> <form-bean name="testBeanForm" type="com.mycom.form.TestBeanForm"/>
</form-beans>
<action-mappings>
<action path="/testAction"
type="com.mycom.action.TestAction"
name="testBeanForm"
scope="session">
</action>
</action-mappings>2.TestBeanForm.java
public class TestBeanForm extends ActionForm {
public FontBean[] getTestBean() {
if(testBean==null)
{
testBean=new FontBean[2];
testBean[0]=new FontBean();
testBean[1]=new FontBean();
}
return testBean;
} public void setTestBean(FontBean[] testBean) {
this.testBean = testBean;
}FontBean[] testBean; }
3. FontBean.java
public class FontBean {
public int getSize() {
return size;
} public void setSize(int size) {
this.size = size;
} public String getFontName() {
return fontName;
} public void setFontName(String fontName) {
this.fontName = fontName;
}private int size; private String fontName;
}
4. my jsp file
<html:form action="/testAction.do">
<logic:iterate name="testBeanForm" property="testBean" type="com.mycom.bean.propertybean.FontBean" id="mybean" indexId="index1">
<html:text name="mybean" property="fontName" value="font1" indexed="true"/>
/* I think when I submit, the testBeanForm will automatically fill its testBean's elements of their fontName attributes with "font1" */
</logic:iterate> <html:submit property="submitValue">Submit Changes</html:submit> </html:form>
5.my action class file
public class TestAction extends Action {
public ActionForward execute(ActionMapping actionMapping,
ActionForm form,
HttpServletRequest servletRequest,
HttpServletResponse servletResponse) throws Exception
{
System.out.println("stepped into action");
TestBeanForm bform=(TestBeanForm)form;
/*I stopped here to check if the form has its testBean variable filled with
"font1" of its fontName attribute, but it doesnt, the testBean of form is just the object I created in getTestBean(),that is, contains two elements, both the fontName attributes of the two elements are null */
return actionMapping.findForward("error");
}
}
so what on earth is the problem?
Thanks&Regards Mike
