JAVA: How to capture java exception stack trace in String

By
Many a times you might need to capture java exception (stack trace) in string, here is a small code snippet to do that: 
StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw, true);
throwable.printStackTrace(pw);
String stackTrace = sw.getBuffer().toString();
This same method can be used to capture string from other streams and assign it to a String/StringBuffer.

Blueprint is an important feature for all those sites which needs to deals with multiple locale and region specific sites. Consider that we have 20 different regional sites and each regional site have 2 locales (English and regional language). Now let’s say you need to do a small update on a English locale page and that changes is required on all sites, there will be 20 pages that you’ll need to visit and make changes one by one (if you have not used blueprint and live copy). With blueprint  we can create a master copy (which is called as blueprint) and create many live copies (which are actual sites) and the benefit you get is that as soon as you do any change in blueprint that same change will be propagated to all live copies pages when changes are rolled out by authors…this is cool. With blueprint you’ll need to apply changes only to English locale page on blueprint and all English locale pages (live copies) will receive that change implicitly. So, how this whole thing works? W

AEM, FORM Submission & Handling POST requests

By
In this article I’ll be specifically talking about how to handle POST request in AEM and what options we have. Please note that Adobe has added more security around handling POST request from AEM 6.x onwards to prevent CSRF attack. If you don’t configure AEM correctly, POST requests will not work even after using any of methods explained in this article.   You can read more about security configurations and restriction at: https://docs.adobe.com/docs/en/aem/6-1/develop/security/csrf-protection.html It is very common use cases to have external application POST some data to an AEM page (e.g. /content/en/home.html) or even submit a form (POST) to same URL. But, as you know that in AEM POST works differently and any POST call to AEM is intercepted by Sling’s POST servlet (org.apache.sling.servlets.post.impl.SlingPostServlet). In some cases org.apache.sling.servlets.post.impl. SlingPostServlet is very useful when you actually want to perform CURD (create, update, read and d
