HI,

  I have a visual force page which displays the list of scheduled Apex jobs. Now there is a schedule button. Onclick of the Schedule button , i need the class to be rescheduled to a value.

I m getting an INVALID Constructor error when i try to do this.

The following is my Controller code:

public class GetAllApexClasses {

       
    public  scheduleClicked () {
        return null;
    }


    public String asyncapexjob { get; set; }

    
    public List<AsyncApexJob> apexclassList{get;set;}
    public GetAllApexClasses(){
    apexclassList = new List<AsyncApexJob>();
    apexclassList = [SELECT ApexClassID, Id, CompletedDate,Status,CreatedDate,TotalJobItems,CreatedBy.Name  from 

AsyncApexJob];
}
public  sheduleClicked () 
{
 

   sheduleClicked p = new sheduleClicked();
        String sch = '0 0 8 13 2 ?';
        system.schedule('One Time Pro', sch, p);
 }
}

 The Following is my VF page code

<apex:page controller="GetAllApexClasses">
<apex:form >
<apex:pageBlock >
<apex:pageBlockTable value="{!apexclassList}" var="apexclass">
<apex:column headerValue="Class Name" >
<apex:outputField value="{!apexclass.ApexClassID}"/></apex:column>
<apex:column headerValue="Completed Date" >
<apex:outputField value="{!apexclass.CompletedDate}"/></apex:column>
<apex:column headerValue="Status" >
<apex:outputField value="{!apexclass.Status}"/>
</apex:column>
<apex:column headerValue="Created By" >
<apex:OutputField value="{!apexclass.CreatedBy.Name}"/>
</apex:column>
<apex:column headerValue="CreatedDate" >
<apex:outputField value="{!apexclass.CreatedDate }"/>
</apex:column>
<apex:column headerValue="TotalJobItems">
<apex:outputField value="{!apexclass.TotalJobItems}"/>
</apex:column>
 <apex:column headerValue="Schedule ">
 
 <apex:commandButton id="cb1" action="{!sheduleClicked}" value="schedule" /> 
  
   
  
 
 </apex:column> 
</apex:pageBlockTable>
</apex:pageBlock>
</apex:form>
</apex:page>

 The following is the error which i m getting.
