This might be a requirement, if you are developing some complex navigation…

Javascript remoting is one of my favourites from Spring’11 release and I’m constantly thinking of making best use of it in Visualforce. I believe remoting is the way to make Visualforce more "viewstate less", this post shows a POC of a complete functional example of a page that searches and updates accounts using Remoting only i.e no viewstate…

As mentioned in my previous post, I was researching/benchmarking on how HTTP Compression with Apache Axis improves performance. The results I got post HTTP compression, are surprisingly amazing…

Force.com sites redirects to “Authorization Required” page in case something goes wrong behind the scenes, for ex…

Winter’11 gave an interesting new location to popular links like “Setup” and “Logout”. They are no longer one click available, you have to click your login name in new interface header to see these links. In first appearance I thought its fine. But over the time when I was working in my winter’11 pre-release org…

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

<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…

apex-lang is an open source Apex library, its Apex port of very popular Apache Common Lang java project. Almost all java developers and open source projects in Java depend on Apache Common Lang. This is really good to see that something similar came to apex in open source. apex-lang is comprising of many Utility classes that port the Apache’s stuff to apex…

Salesforce releases are exciting for me, I am always eager to know whats coming next in this release. While writing some other blog post on “Chatter for Winter’11”, I was going thru Quinton’s blog post on Salesforce blog. On a screen shot on this blog post, I noticed a few interesting things (might be related to Winter’11 release), those are highlighted in red circles in picture below…

This post explains how to best handle/access primitives, lookups and child relationships, when working with Partner-Sobject compiled from Salesforce WSC WSDL complier…

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…

I mentioned few days back about starting integration of Tolerado with WSC. The latest updates on this integration are

Tolerado-WSC is code complete [beta* :)]. I am testing the API now…

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…

Developers are always too concerned about many things, like making the Web Service call work right for them and implementing the biz requirements. So handling exceptions and giving them proper treatment is mostly not a priority…

Web Services are something that are either used as provider or client by almost every developer. Web services are usually exposed via SOAP, these days RESTful web services are common too. One thing common in all types web services is HTTP protocol, its the base protocol wrapped by SOAP / REST implementations…
