The following shows one entity, where the same product (same pid) is given a rating by two different users (different uid). I want to get the latest data about average_stars (namely the second column data), which is 4.50. I used a MySQL command findTopByProduct, which shows me the older average_stars instead, namely 4.00. I tried findBottomByProduct, which turns out to be non-existent. I will really appreciate anyone who can help me with this simple question. Thanks in advance!
I have found the answer: findTopByProductOrderByPruidDesc

I have a java application which needs the 'TIME' last time my app has run.
i am running jar manually.Where should this last time run info can be stored .Should i store the last run time on file or some environment variables or some other?Please suggest best way of doing this.
A straight-forward way would be with the Preferences API. You won't need to care how the data is actually stored, or where.

So, I wanted to write myself a Java program, which will send a bunch of data (probably formatted as JSON) to my website, which will then write that data to MySQL, but I also want my website to get the IP, from which this data was sent.
But is this even possible? I don't have too much experience with PHP :/
The answer is here: http://stackoverflow.com/questions/15699101/get-the-client-ip-address-using-php
Easy solution is:
$IP = $_SERVER['REMOTE_ADDR'];

I have set up a JPA Database connection for my Eclipse Java project to a PostGreSQL database. I was wondering if there was a way to create a class for one of the tables without doing everything by hand.
Yes,you can use hibernate reverse engineering. Pretty much with some simple set up, it will generate java pojo class for you.

I am starting working on a new app which will show news of different channels. But I am bit confused that how to get data from websites which will update automatically. Am I need their API keys for integration or some other method. please give me some suggestions.
News sites will likely have RSS feeds. You can use classes from System.ServiceModel.Syndication to parse them. In-depth discussion here.
