Custom Labels are key to create multilingual Salesforce apps. Developers usually move their page/class to Custom Labels in two steps…

What if you want to create a Batch Apex Job that uses SOQL having aggregate functions like SUM, MAX, and COUNT on top of results grouped by the “GROUP BY” clause? You can’t easily create a Batch job via QueryLocator, as shown below. When working with Batch Apex in Salesforce, you might encounter a scenario where you need to run SOQL queries with aggregate functions like SUM, MAX, or COUNT while grouping results using the GROUP BY clause.

<apex:actionRegion /> is interesting and somewhat ignored tag in Visualforce. Tag is ignored, because Visualforce documentation is not in depth, to explain the real utility of this tag. So this post explains some stuff around action region to make it easy for developers to understand…

I stumbled upon a strange Batch Apex issue today. My batch job was going well in few SFDC orgs; after deploying the same to a new org it stopped working completely. I just see, “First error: Attempt to de-reference a null object” in debug and apex logs. After adding a lot of debug statements in both start() and execute() method, I found that…

You must be stuck up with Apex, when sorting is required on instances of user defined classes and pre-loaded Sobjects. Unfortunately standard Apex API just gives a method List.sort(), that just works with primitive data types…

As a developer, “Chatter” is something I love most, apart from other goodies like Sites etc given by force.com platform. So can’t resist my temptation to digg what’s next with Chatter in coming Winter’11 release. Regarding this I got good insights from…

This post compares “com.sforce.soap.partner.sobject.SObject” generated by compiling Partner WSDL with WSC, to SObject class generated with Java libs like Apache Axis. This might be of interest for those developers who compiled Partner WSDL with other libs like Apache CXF etc..

Yesterday’s blog post explained how to best use Apache Axis and WSC stubs in parallel on same JVM or Project. This post reveals another small trick for developers using both WSC and Apache Axis WSDL2Java stubs together in a project/jvm. The trick focuses on reducing the number of login() call via Partner or Enterprise Stubs…

This post is specially for those, having a Java Application(Production) working with SFDC web services via Apache-Axis stubs(WSDL2Java), but because of known advantages from WSC, you want to add some new functionality, like Bulk API as mentioned in SFDC blog here…

This post is for developers working on Visual Force. I came across an interesting way to control the rendering of HTML markup; previously, I was using “<apex:outputPanel .. />” for controlling the rendering of some HTML markup. This approach works….

I am researching on how to best use & integrate “WSC” with Tolerado. This research mainly focuses on

How to preserve and reuse a single sfdc login session across the all the WSDLs. This should again go in transparent fashion as with Tolerado for Apache Axis…
