I need an open source GIS that allows one to view/zoom/click the maps using a web browser and should be java compliant (deployable on a java app server).
Well, I have tried to structure the requirement in 'what-i-have' and 'what-i-need' lists:
Inputs:
Location: lat/long
Data : Text to display
zoom level: (assume there are about 5)
Output
Data displayed on a Map
Would appreciate all the help I can get.
Thanks.
UPDATE: GeoServer + OpenLayers seems to be the best fit for this requirement
GeoServer: http://geoserver.org/display/GEOS/Welcome
...is what I use. You have work ahead of you no matter what you pick, though. Setting up data sources and making them look nice is a decent amount of effort.
For the client side, OpenLayers is an excellent Javascript library.
I agree with the geoserver response and all the rest of the responses ignore your statement that is has to work with Java. The only other bad option would be to write something yourself using geotools.
Go to the OpenGeo site and see the stack they support. That is the stack you are probably most interested in deploying.
I guess you'll need:
GDAL/OGR to translate the data into a kml file example
Take that KML file and pump it into either:
a. Google maps api or openlayers
b. I've had lots of luck using featuresever which I personally recommend

I have pretty standard java project with standard gradle layout, all sources are stored in git. I want to write documentation in markdown (or similar markup language) and keep all files in project directory (e.g. docs/ folder in the root). Then I want to generate static site or push my sources somewhere to have access to full documentation in html (should be self-hosted solution).
It will be good if I'm able to add simple link to other articles (like I do it in any wiki engine by using [[article]]). And It would be perfect if I've been able to add quick links to javadoc by the same technique as link to articles. And also it would be perfect if it has had built-in search engine.
I've gone through couple of static site generators but I didn't find anything which can satisfy my requirements at least half. Is there something like that? Or I need to code it by myself (I know it won't take to much time)? Maybe there's more common use case for documentation?
You have to use the concept of Doclets. There are some out there. Maybe just try this one:

I want to read content(text data) from jpg image. Can someone give me a sample java program to refer.
The image would be a white page. The text would be in black. How do I extract data(lines/alphabets) and print it.
Help would be much appreciated.
Thanks
Take a look at this SO question for OCR in Java. Once you are able to pull out the text, doing manipulations on the text can be taken care of by using Apache Lucene. Also, in case you are interested in image metadata as well, Apache Tika might be useful.
Pay attention for products by ABBYY. For example there is ABBYY Cloud OCR SDK – cloud-based OCR technology. It has very high recognition accuracy, a lot of documentation and good support.
You can try to use it in several easy steps:
1. Create a free account
2. Create an application using code samples for Java
If you need additional help, use ABBYY's forum or publish your questions in comments below.
I work for ABBYY and ready to help you.

Has anybody used the HQAPI to fetch the metrics of a resource programmatically? I want a sample code which uses the HQAPI to fetch the metrics of a resource.
There is a treasure trove of examples here
http://svn.hyperic.org/projects/hqapi/trunk/src/org/hyperic/hq/hqapi1/test/
and I am trying to put together some explanation here
http://www.javamonamour.org/2012/05/creating-alert-recovery-with-hyperic.html
They seem to have plenty of examples on Github e.g.
https://github.com/hyperic/hqapi/blob/7b19d6b0ebfb8cfb2903d4a495ab0368ba3e6aeb/src/org/hyperic/hq/hqapi1/test/Metric_test.java
Also there is an example in their docs:
http://support.hyperic.com/display/DOC/HQApi+Java+API
The are actually a lot of ways you could do this:
Run the plain old hqapi.sh resource list (or like) commands, which could be very slow.
Paste directly in your browser window a restful URL:
http://__host__:7080/hqu/hqapi1/alert/find.hqu?begin=1344004728555&end=1444004728999&count=100&severity=1¬Fixed
Use curl to achieve that:
curl -u hqadmin "http://__host__:7080/hqu/hqapi1/alertdefinition/listDefinitions.hqu?resourceId=10201"
I personally like using a scripting language like Python to do this.
Then there is Groovy script, which you can run in a Groovy console under the administration tab. Check the hqapi1 hqu plugin.

My requirement is to access moodle as a backend engine and front end will be mint in Java[jsf]
now I want to know that is there any interface available to access Moodle from Java , using WebServices or any APIs or anything.
Initially I tried using Sakai which is in Java, but the problem is there is no clear API written for it.
So let me know the option for using Moodle from JAVA.
Also if it is possible than what will be the feature available through the WebServices or API. ?
Or any other LMS that is in Java and provide API or WebService to make this working.
I reviewed many LMS (dokeos, docebo, ATutor) last year and to be frank all of them sucked. Moodle was the most stable, had more plugins and a huge community.
I came across Project Sakai, I havn't tried it, but sounds promising. Something very interesting from Google is cloudcourse (in python I guess, but looks awesome demo). But not a complete LMS (compared to moodle).
You forgot to add Chamilo they have a list of available web services (SOAP) that you can use to create courses, users, add users to courses, etc
https://www.olat.org/ and https://www.openolat.com seem a good alternative to moodle.

I'm looking for a Java framework to help with some data mining specific to images. We have a set of historical images that I would like to categorize and classify. I'm was hoping to find something like weka http://www.cs.waikato.ac.nz/ml/weka/ or Marsyas http://marsyas.sness.net but more specific to sifting through image data to find patterns. Any suggestions?
What about using the OpenCV library for Processing? Technically, Processing is not Java, but it runs on the JVM and shouldn't be difficult to get working. OpenCV is the standard choice for computer vision, which is what you're trying to do.
I played around with Neuroph (http://neuroph.sourceforge.net) which is a neural network framework for Java, and they have a very nice image recognition tutorial that I think everybody should read, but specially if you're dealing with image recognition: http://neuroph.sourceforge.net/image_recognition.html
Have a look at OpenCV with JavaCV libraries from Google. Simply use function from that library to find whatever patterns you want.
It'll be a great surprise for me if you can find such library.
I can advice you to find some library with ART neural network implementation. Then you can add some photos to each category you want to recognize and ART algorithm will try to recognize all other photos.
