vesamenu.c32: Not a COM32R image

This was the error message which came on booting Mint 11 Live CD on a new machine.  The bootable CD was created using Ubuntu 'Startup Disk Creator'. After googling I found the solution was to type live at the prompt

boot: live

JQuery UI Autocomplete with Stripes

While trying to integrate JQuery UI Autocomplete problem, the autocomplete was working with static JavaScript method but not working with values sent from the server.

Now the new JQueryUI expects JSON instead of the deprecated version which expected Strings separated by new line character. Even when I was sending JSON data, the values were not displayed at all.

The problem was that I was using ' to quote the strings instead of "

attempted to return null from a method with a primitive return type (void).

Problem:

I was encoutering this excpetion while inserting a row in the database using myBatis 3. 

Solution:

I had forgotton to change my mapper file xml tag from <select> to <insert>.

Cause

I copied the SOLR directory to another machine and when I fired up SOLR received this error.

Solution:

The error message was misleading as even though I started the server with -Dsolr.solr.home option the error was still the same.

The index was somehow corrupted and when I deleted the $SOLR_HOME/solr/data/index directory and restarted SOLR it worked fine. Obviously after that the data had to be reindexed
