I want to automate a server health check that is configured using weblogic. I have to login to weblogic console to view server's health. If I think about automating this process, then the only way known to me is selenium. But i dont want to use it. Is there any other way through which i can login to weblogic console and get the health status of server in java
I think it is pretty simple: if you don't have components at hand that provide you the functionality you are looking for; then you will have to see what it takes to implement it by yourself.
You could start here for example. Or for a slightly different approach there.
You can do the API automation, instead of UI automation. You have to find out if there are any API exposed to get the data. If there are APIs available then you can use httpClient library in java for API automation.

I'm on a student research team currently working on a Java project in which we want to be able to gather some info about specific external programs in CentOS 7. Some potential examples of data we might want to gather would be the URL from firefox, or the coordinates from Google Earth. Thus far, looking into how to implement this has mostly led me to using JNA and ptrace.
Is this a good route to take to tackle this problem? And if so, what can I use to find the location of specific information about the programs in memory?
JNA and ptrace are quite low level things. To run system applications you should use:
exec method of Runtime class
Apache Common Exec
Last one is more useful.
But it seems you don't need to run any application at all. To get information from Google Earth you can just use special web API - Google Maps APIs Web Services. If you want to send HTTP request you should try Apache Http Client. It's very powerful library and i'm pretty sure it's all for you need.
PS. More convenient client Java Client for Google Maps Services
PS1. I think java is the worst choice to work with OS and native applications. I see 2 ways to use it:
write agent on C/C++ which will be gather this information for java manager. It's a hard way
use hacks and tricks like here is there a way to get the url from current tab in google-chrome or here Possible to catch URLs in linux?. It's more easy but you will have restricted amount these hacks. And it will work not for all applications and cases.
I want to create a websocket Java API for these requirements:
"When the user logs into my application, if he enters a page which has constant updates from the server, then the Java API should identify the user and keep pushing the contents on a regular interval"
So for this I want to get started in creating a generic Java API so that for other pages, which requires push from server, I can use the APIs instead of reinventing the wheel everytime
What are the things I should take into consideration and how should I approach this problem
Please key in your thoughts
Thanks in advance
GitHub has a number of libraries which deal with Java and WebSocket. You can build your application on top of one of them. Examples are vert.x, SockJS, Atmosphere etc.
At the SockJS page you can see a list of clients/servers for working with it.
IMHO It is better to re-use one of the existing libraries/frameworks than building your own, because yours is a common usecase and working with web sockets, providing corss browser compatibility etc are not trivial as of now.
I'm building a Spring web app and up until now all of my testing is using a browser.
This involves starting the server, opening a browser window and checking to see if accessing any of the pages causes an error.
This is starting to get repetitive and doesn't seem to be the most efficient way to do this.
Since the Junit jar file is already in my project, could it be used as an alternative to this browser testing and, if so, any tips on how to get started making JUnit simulate the act of opening a browser to access the web app?
Take a look at Selenium. It allows you to script functional tests using JUnit or TestNG and execute them in a browser, automatically.
You can use the HTMLUnit extension to script to drive the web site from JUnit.
I used a while back and worked fine for thi site I was doing then.
see http://htmlunit.sourceforge.net/
I suggest you to try the Robot Framework. This is an open source testing framework developed by engineers in Nokia Siemens Networks.
It is primarily built on python and the Selenium testing libraries. It also includes support for testing Java/J2EE server side code through Jython libraries. I personally use it in my work sometimes, and writing a test case is just as easy as describing an end-to-end flow through the use of Keywords (most of required ones are already inbuilt). You could go ahead and give this a shot if you find Selenium a li'l tough to work with. The Robot framework provides a fairly simple abstraction over raw selenium, coupled with the power to make Java/J2EE server-side calls too.

I'm very new to JUnit, but I want to set up some tests which does the following..
Tests a range of server to server API calls - verifying the responses are correct - I can do that fine.
Open a web page, enter data onto it and verify what happens on submit - This I am struggling with. Is it even possible?
I am thinking that I could call a web page using a server side http web request, but I'm not sure how I can interact with the site itself, i.e. enter data into the forms.
Any thoughts?
Thanks
Steve
You could use Selenium for this. I suggest you use the version 2 which is currently in development and should have a beta available soon (alphas are already available).
Have a look at Selenium, it's a system to test web applications (and de facto websites) you can write all your tests in java. There is an ather project named Tellurium, based on Selenium but Tellurium works with groovy and a DSL, it might be easier to handle at first.
How does this works ?
First you create tests in java (Selenium) or groovy (Tellurium)
Then you start your tests. It will work with your web browser. The application will interact with your browser to test every inch of your application (as you coded it)
At the end it give you a report about yours tests, just as JUnit do.
You can also exploit the nature of the web. There's no real reason to render a form, fill it out and submit it to test the form processing code. The display of the form is one HTTP request, and the submission is another. It's perfectly reasonable to test form submission code by mocking up what a browser would send and asserting that it's handled correctly.
You do need to make sure that the form rendering and submission test code are in sync, but you don't necessarily need a full integration for this either.
There are tools that allow testing without booting up a browser... one that springs to mind is HTMLUnit (and there are others). If you find that Selenium is a pain to write, or the tests brittle or flakey, look for simpler tools like this.

I want to screen-scrape a website and for that I want to use Http, Socks4 and Sock5 proxies. So my questions are as follows:
Is it possible to use these proxies through Java without using any other external API? For instance, Is it possible to send a request through HttpURLConnection through theseproxies?
If it is not possible, then What other external APIs I can use?
I was doing it by using a headless browser provided by HtmlUnit but it takes time to load even simple webpages, so could you please suggest me other APIs (if any) that provide headless browsers that are fast in loading webpages. I don't want to open webpages that contain heavy AJAX or Javascript code. I just need to click on the forms button through the headless browser.

Yes, you can configure proxies by either using (global) system properties, or using the Proxy class, or using a ProxySelector. The two later options are available since Java 5 and are more flexible. Have a look at Java Networking and Proxies as mentioned by jarnbjo for all the details.

Unfortunately, the first alternatives I can think of are either HtmlUnit based (like JWebUnit or WebTest) or slower (Selenium, WebDriver - that you can run in headless mode). But maybe you could try HttpUnit if you don't need advanced JavaScript support.
Yes, that is possible. You can find the configuration options for different network proxies here.
