I have a form which has five tabs. In one of the tabs(background.jsp) on change of a checkbox(be in checked or unchecked) I am trying to set the flag of (hasGenderChanged) in jsp to true and use a request type to send it to my java code.

Below is the code structure. I am getting an error which reads: Cannot find bean org.apache.struts.taglib.html.BEAN in any scope in edit_Education.jsp. Below is the code structure. Any help will be greatly appreciated.



Introduction.jsp has all the header tabs and at the end of it has
<template: get name='content-area'/>
On click of save button in this page I want to send if a check box has been changed during filling up a form. If changed want to send true to java component from JSP.


In edit_Education.jsp:

<template: insert template='education/Introduction.jsp'>

<logic:equal name="educationForm" property="selectedOption" value="0">
<template:put name='content-area' content='education/background.jsp'/>
</logic:equal>

<logic:equal name="educationForm" property="selectedOption" value="1">
<template:put name='content-area' content='education/eduqualification.jsp'/>
</logic:equal>

<logic:equal name="educationForm" property="selectedOption" value="2">
<template:put name='content-area' content='education/workexperience.jsp'/>
</logic:equal>
</template: insert




Since the forms on each tab are huge I want to trigger an action only if a checkbox has been checkbox in background.jsp

In background.jsp

Inside the html tags of a checkbox this is the function I have


><script>
function validate(){

document.educationForm.hasGenderChanged.value="true";
}
<html:form action="/processEducationAction" target="CONTENT-AREA">
<html: hidden property="hasGenderChanged"/>
<input type="hidden" name="hasGenderChanged" value="" scope="request"/>


</script>

<tr>
<html:checkbox property="selectOptions.selectGender" onchange="validate()"/>
<bean:message key="education.selectedOptions.label.selectGender"/>
<tr>
</html:form>

In educationForm.java I have a boolean hasGenderChanged; variable and setters and getters for this.

I am not sure how this value, hasGenderChanged in background.jsp can be made accessable to in edit_Education.jsp.

Thanks in advance for the help.

Hello All,

I have a method that returns a collection. The aim is to filter out data such that this collection has all ratings greater than 0 and less than 3 into it.

My expression is not working well. Is this the right format for using to select ratings greater than 0 and less than 3 as my collection is returning all the values. Any help with this will be highly appreciated.

public DBCollection displayRatingzerotothree() {
BasicDBObject query = new BasicDBObject();
collection = db.getCollection(Collections.COLLECTION.getName());
query.put("rating", new BasicDBObject("$gt", 0.0).append("$lte", 3.0));
DBCursor cursor = collection.find(query);
return collection;
}
