I need to make an on-line system/webapp/server that connects to an mySQL Server. this web app/server must accept incoming communications from an android app and then make changes to the database. Also there needs to be an "Web Admin Console" to do manual data manipulation.
I was considering using Java with Tomcat for the web application the system needs to run on:
open source frameworks
be well documented technology
secure data transmission
are there any other software/languages i could use? how do i set up the web console? there needs to be an SSH access as well...
How do I start with making this online system?
You can develop complete system in JEE6. You can choose RESTful WebServices for integrating Android Application and Web Application too. For developing web application you can go with JSF if you want rich look and feel. Else you can stick with normal JSP and frameworks like jQuery and Twitter Bootstrap etc.

I am creating a complaint management system for my university final year project with two components
1-an android app through which the user launches a complaint.
2- web application for admin that can see and take action on complaints launched through the app
PROBLEM : I need to connect both of these application to a single database, how do I go about doing that ?
Should I use API PHPmyadmin ....I seriously do not know where to begin.
Neither should connect to the Database. You frontend / client / app should never talk to the DB directly.
You need to create an API in between, that API is hosted on your server and talks to the Database. The clients talk to the API and the API can manage who is allowed to do what, determine if they are authenticated, do some logging, etc.

I have to design an application which gets requests from multiple sources like Web service (can be SOAP or REST), online system, Message Queue or some batch job. Application needs to interface with 2 more applications for getting results. I understand that this can be done using microservices. This application needs to be built in Java. I am looking for some framework which can help me with accepting input from multiple sources as mentioned above.
If you want to build a lightweight simple layer (single app) to cater all these requirements, I would recommend using Apache Camel. This single app can listen to rest/soap requests, read from file system, JMS store, database etc. You can even embed it into another application and have all sorts of integration with different data source and excellent and easy to configure routing and transformation engine. Plus the documentation and community is awesome.

I want to develop a Web application in which front end will be developed in HTML, C#, ASP.net and server side will be using JAVA ( JAX-RS jersey ).
So, the front end will be running on IIS server and java will be running on Tomcat server.
How to consume Java REST API from C#?
I mean is there any way to to communicate between two different servers ?
Note: This is my second time asking question on this platform, so I am sorry if my question doesn't make any sense.
Perhaps you can look into using the Spring framework. With the Spring framework, you can build a RESTful web service that has end-points with which your front-end can communicate. It works like the C# Web-Api, in that you can define a "base URL" and other specific URLs that you can link to a function in your Java code.

I'm a Java developer that hasn't coded in about 5 years and wants to polish up my skills. I am going to create a small app that uses an OAuth 2.0 authentication flow and then makes a few REST calls and displays the results. I've got my credentials setup with the OAuth provider.
I used Eclipse back in the day, is that still a solid IDE for this type of project? If I want to share the app with others to show my work, where could I host the code?
Thanks for these and any other pointers.
first off - yes, Eclipse if still a good choice.
if you can, make you app a web-application, and then you can host it in PaaS such as Google AppEngine. then the app itself will be always accessible from any machine that is connected to the web. this way, you will be able to show it to anyone you want.
if you only want to show the code, then GitHub or Google Code are a good choices.
HTH

My webapp exposes some application-specific metrics (think "orders placed") via JMX, which I'd like to monitor using Hyperic HQ (open source edition).
According to the Hyperic Inventory Model, my Linux server is called a Platform hosting my Tomcat 6 Server, which in turn hosts Services (e.g. "Servlet Monitor") that finally expose Metrics (e.g. "Error Count per Minute").
I assume I need to develop a custom Hyperic plugin (just an XML file, really) that would point the agent and server at the correct JMX MBeans. Ideally, I would like to see my webapp listed as a Service hosted by the Tomcat 6 Server, but looking at the Plugin Development docs, that doesn't seem to be possible.
Maybe that's not too bad anyway, because in theory, I might want to switch my app to Jetty. But I figure that's a very common use case, so are there any best practices? I couldn't really find any examples of this on the web, so I thought I might just ask the experts..
Please note: The Hyperic docs I linked to seem to require an account to view.
