Hi All,

Before executing Batch apex how am i getting the Jobid of batch apex in finish method as shown below.

Please explain as i am a new to salesforce.

global void finish(Database.BatchableContext BC){

// Get the ID of the AsyncApexJob representing this batch job
// from Database.BatchableContext.
// Query the AsyncApexJob object to retrieve the current job's information.

AsyncApexJob a = [SELECT Id, Status, NumberOfErrors, JobItemsProcessed, TotalJobItems, CreatedBy.Email FROM AsyncApexJob WHERE Id = :BC.getJobId()]; ( how do i get job id in finish method before executing batch apex )
// Send an email to the Apex job's submitter notifying of job completion.

Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage(); String[] toAddresses = new String[] {a.CreatedBy.Email}; mail.setToAddresses(toAddresses); mail.setSubject('Apex Sharing Recalculation ' + a.Status); mail.setPlainTextBody ('The batch Apex job processed ' + a.TotalJobItems + ' batches with '+ a.NumberOfErrors + ' failures.'); Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail }); }

 

hi All,

I've witten a code which has to take input from an input box and add the input to select options until submit button is pressed.
that is as long as i give input and click on add button it should keep on adding the given input texts to select option list. and if i click on submit button it should display the selectoptions list.

vf code :

<apex:page Controller="selectlistoption">
    <apex:form >
    <apex:pageBlock >
        <apex:pageBlockSection >
         
            <apex:outputlabel value="Enter Country"/>
            <apex:inputText value="{!str}"/>
            <apex:commandButton value="Add" action="{!setCountry}"/> 
            <apex:commandButton value="submit" rerender="showdetails"/>
        </apex:pageBlockSection>    
        
    <apex:pageBlockSection id="showdetails">
      
            <apex:selectlist size="1" value="{!str}">
           
                <apex:selectoptions value="{!country}"/>
                 </apex:selectlist>
        
 
        
        </apex:pageBlockSection>
                    </apex:pageBlock>
    </apex:form>
 
</apex:page>

Controller :

public class selectlistoption {
    
  
      public   string str{get;set;}
    
       public  list<selectoption> country{get;set;}
    
    public pagereference setCountry()
    {
         
        country.add(new selectoption(str,str));
        return null;
       
    }
    
   

}

Error :

System.NullPointerException: Argument 1 cannot be null
Error is in expression '{!setCountry}' in component <apex:commandButton> in page selectlist: Class.selectlistoption.setCountry: line 11, column 1
Class.selectlistoption.setCountry: line 11, column 1
