UPDATE (18th Nov, 2011): I carried out a clean installation from a USB drive, and no longer have the purple/blank screen problem while loading the 3.0.0-12-generic kernel. I can conclude that a problematic web upgrade process prevented the newer kernel from loading. Possible fixes are being discussed on various forums, but none of them have worked for me. I’ve been running Ubuntu 11.04 (Natty Narwhal) for several months and have been satisfied with the experience. In October 2011, the newest stable Ubuntu 11.10 version (Oneiric Ocelot) was announced. The upgrade to the new distro can be carried out by running the command: sudo do-release-upgrade You could also enable automatic updates, like I did, and have Natty Narwhal prompt you to[…]

While working on the Oracle Application Framework, my Application module’s class file was behaving in a strange manner. When it was deployed on Apache and run, it was throwing the following Error: oracle.jbo.JboException: JBO-29000: Unexpected exception caught: java.lang.ClassFormatError, msg=oracle/apps/fnd/framework/test/updateAMImpl (Invalid pc in line number table) at oracle.jbo.common.ampool.ApplicationPoolImpl.doCheckout(ApplicationPoolImpl.java:1619) at oracle.jbo.common.ampool.ApplicationPoolImpl.useApplicationModule(ApplicationPoolImpl.java:2366) at oracle.jbo.common.ampool.SessionCookieImpl.useApplicationModule(SessionCookieImpl.java:427) at oracle.jbo.http.HttpSessionCookieImpl.useApplicationModule(HttpSessionCookieImpl.java:214) at oracle.apps.fnd.framework.webui.OAHttpSessionCookieImpl.useApplicationModule(OAHttpSessionCookieImpl.java:473) at oracle.jbo.common.ampool.SessionCookieImpl.useApplicationModule(SessionCookieImpl.java:398) I Googled on this error a lot, but most of the suggested solutions spoke about compiling the class with a different JDK or a different Java version and deploying it again. I tried to do that, but the error persisted. Decompiling using javap I thought of decompiling the deployed class using the javap utility – if it would fail to decompile, that would[…]

Flipkart is often called the Amazon of India. Set up by two ex-Amazon employees as a startup in 2007, it brings Indians the best of the online shopping world knocking at their doors. I’ve been a regular buyer of stuff from Flipkart, and my experience with them has been simply amazing. So here’s my review on Flipkart, and what I believe has been helping them to be highly successful. 1) They provide an estimated delivery time – and keep their promises Flipkart does not think short term by providing overly optimistic delivery times. Online stores will ensure returning customers only if they keep their promises, and Flipkart seems to keep that in mind with their fairly accurate delivery time estimates.[…]
