IBM Blogs Throw a Mean Curve Ball, 404 Style

Posted by jonathan at 5:15pm EST on 09/09/2007

Some how I ended up browsing IBM’s website tonight and started cruising around. I finally noticed they had some blogs setup, so naturally I went to go check them out to see what they were running. I quickly noticed the .jspa file extension so I knew they were running something home-brewed. But shortly after trying to visit not one, not two, but more than three of the blogs, I noticed a pattern.

IBM’s software is completely error-driven. Their in-house blog software is spewing errors like there’s no tomorrow. Take a look below.

IBM Blog Errors

Here is one of the specific errors that the page is spitting out to me.

Error Message: SRVE0190E: File not found: /dw_blog.jspa

This once again makes me very thankful that I’m not a software developer (especially not in Java or JSP).
