Please help me to get knowledge about struts tags(html,bean,logic).
hai Friends,
I know basics of struts. I have done basic examples.
I have to know , how to get dynamic values in "view".
Instead of writing like this..
<html:select property="color1" size="4" >
<html:option value="red">red</html:option>
<html:option value="blue">blue</html:option>
<html:option value="green">green</html:option>
<html:option value="orange">orange</html:option>
<html:option value="red">red</html:option>
<html:option value="pink">pink</html:option>
</html:select>
How to use <html:options> tag to get dynamic values.
I have to get knowledge about this tags, so please suggest some
sites (or) send some materials (or) send some live examples("awm_riaz@yahoo.com"). It will very useful..
thanks friends....

you have to have a list of label and value pairs in you ActionForm then define it in your jsp to able able to use it in your <html:options> tag
ActionForm
public final class ColorForm extends ActionForm {
...
public String color;
public void setColor(String color) {
this.color = color;
}
public String getColor() {
return this.color;
}
public List getColorList() {
List l = new ArrayList();
ColorLabelValueBean lvRed = new ColorLabelValueBean();
lv.setLabel("Red");
lv.setValue("R");
l.add(lv);
ColorLabelValueBean lvGreen = new ColorLabelValueBean();
lv.setLabel("Green");
lv.setValue("G");
l.add(lv);
ColorLabelValueBean lvBlue = new ColorLabelValueBean();
lv.setLabel("Blue");
lv.setValue("B");
l.add(lv);
return l;
}
...
}
Label - Value Bean
public final class ColorLabelValueBean implements Serializable {
private String label;
private String value;
public void setLabel(String label) {
this.label = label;
}
public String getLabel() {
return this.label;
}
public void setValue(String value) {
this.value = value;
}
public String getValue() {
return this.value;
}
}
JSP
...
<bean:define id="colorListOption" name="ColorForm" property="colorList" type="java.util.List" />
<html:select property="color">
<html:option value=""></html:option>
<html:options collection="colorListOption" labelProperty="label" property="value" />
</html:select>
...
Good luck!
