I am very new to Aptana. I like it but I am having some issues.
Very simply: How do I deploy or "add" a web project to a tomcat server in Eclipse?
Also, if you can send me any beginner guides on this kind of development specifically (Deploying Aptana projects in Eclipse) it would be much appreciated.
So:
I know how to create a project and run the internal Aptana server to preview the page.
I do not know how to deploy it to a server other than the internal one.
I have looked around and I mostly find forms and sites saying use the "Run Web Deployment Wizard".
I do not understand how to use it (mostly because I am trying to deploy on a local tomcat server created using eclipse.
The "Deploy App" function is also confusing because I think I can get it to sync with a server but.... thats it.
The non-Aptana way seems very easy and straight forward:
Create dynamic web project
add to server using "Add and Remove" function
done! access the page using a browser!
Umm should I try pure Java EE? I heard it might be easier because Aptana is "bloated and tries to be too many things while excelling at none"-Another form
Slightly off topic but, opinions? also I am assuming that git works well with Java EE like it does with Aptana.
Don't know if i get it wrong but you could try the following:
In Aptana Studio select Window->Show View->Servers
this should open the server-tab on the bottom, where the console resides.
Now you can add an external webserver by clicking the arrow left to the "add server"-button.
you should now be able to add the created custom-server as your projects deployment-server

I have a Java Web Service project which was just handed over to me by a colleague who just resigned (no one is assisting me in my new company). Im new to Java (J2EE) and my background is .Net + frontend + azure so I am pretty much very confused with setting up and running the java project. Also, Since my background is .Net Im referencing everything with how things work in Visual Studio from running a project, setting up a project to setting up and debugging a WCF project which I realized now is very different from eclipse + java.
I would really appreciate if someone could explain to me how I can run this project which is supposedly a java web service (as I was told)?
First I have a project that is like this:
Im assuming that the project boxed as blue is the webservice (and the rest are just libraries)? Is this correct? if so how do I run and debug the project using eclipse
Second when I click on debug as -> debug on server this is all I see:
Another colleague told me to install JBOSS (I haven't installed a server in eclipse) because that is what they used. Is there good documentation (step-by-step guide) on how to install JBOSS to run in eclipse. Im assuming that JBOSS + eclipse is like IIS express + Visual studio. Are there also other alternatives to JBOSS + eclipse like perhaps tomcat + ecplise that I can configure.
I really really find it hard to setup the java web service project in eclipse I have little to no prior experience with java j2ee programming especially with web services so any clarifications with my questions would be much appreciated. To sum up:
How would I really know that the project is a java webservice?
If so, how do I run the project and host the project using debugging in eclipse with tomcat or jboss?
I would appreciate if anyone can point me to the right direction of figuring out the source code
From here we can only guide you, you will have to go through some tutorials to understand how java projects work.
Your project is a webservice project according to your web.xml file because its having context params for rest.
the context param sets a front url to your webservice which in this case is gametime.
Check these tutorials and you will understand how it works
http://www.mkyong.com/tutorials/jax-rs-tutorials/
Create simple examples given in the above tutorial and then you can execute your's program
Jboss is a application server which we use to run our app.
You can install jboss in eclipse or you can use it externally also.
To install eclipse and jboss you can follow the link
http://theopentutorials.com/tutorials/java-ee/installing-jboss-tools-in-eclipse/
The other option is to download eclipse and jboss seperately
and use them.
Go to jbosshome/bin
If you download both of them seperately
then in that case for jboss
Invoke the add-user.sh or add-user.bat script. ...
Choose to add a Management user. ...
Choose the realm for the user. ...
Enter the desired username and password. ...
Choose whether the user represents a remote JBoss Enterprise Application Platform 6 server instance. ...
Enter additional users. ...
Create users non-interactively.
After this go to eclipse and follow steps of below link to add jboss to eclipse

A Java web application among other things has a predefined directory structure including folders named WEB-INF, WEB-CONTENT etc.
On how to deploy a web application to Tomcat via Eclipse you can follow the steps in this tutorial.
I have JBOSS server. I used to make web applications using just notepad++. I used to create the necessary folders like web-inf and files like web.xml. For larger projects doing all this and manually compiling has become cumbersome. I want to use eclipse for that. I saw this tutorial - http://www.eclipse.org/webtools/community/tutorials/BuildJ2EEWebApp/BuildJ2EEWebApp.html . But I don't understand how to make a server. I already have a server. What I want to do is write JSPs and Servlets in eclipse and the build should automatically be deployed in jboss server.
How to to this?
Install JBoss Tools
After that follow the instructions from here to get started and deploy apps to JBoss Server.
To automatically deploy apps after the build you could use a build tool such as ANT or Maven.
I wrote a tutorial for this some time ago: Setting up web development environments with Eclipse
It shows how to setup JBoss within Eclipse (in addition, it also shows how to setup Tomcat and Weblogic), and also shows how to build a simple sample Servlet to verify the proper installation.
If you already use JBoss on the server side, then have a look at the client side as well: http://www.jboss.org/developer
(I haven't tried it myself, but...)
Just open eclipse then go to:
"Help-> Check For Updates" It will check for eclipse updates and installs new availables.
Now "Help -> Eclipse Market Place" Search for "Jboss tools" from search result select one(as your eclipse version) and install it. It will add adapter for new jboss versions.
Now add new server from server view select Jboss version then next add your Home directory of jboss. Then finish.
Step 1 is optional but it sometime it helps.
I am very new to Tomcat and web development in general and apologize for what may be a very silly question.
Consider 2 situations:
1.
I start Tomcat outside of Eclipse.
I use eclipse to create a war file.
I deploy it via admin console.
All is ok
2.
I start Tomcat via Eclipse
I can't access admin console
http://localhost:8080/manager/html greets me with 404 error
Same page is behaving properly when Tomcat is started outside of Eclipse
Please advise

You need to configure Eclipse to take control of your Tomcat installation. To do so:
double click on the Tomcat Server in the Servers view
under Server Locations, select Use Tomcat installation
This is illustrated on the screenshot below:
Eclipse creates a new Tomcat configuration separate to your Tomcat installation, in the 'Servers' project. This allows Eclipse to deploy webapps without interfering with anything you've done in your installation (via the manager app or by editing config files manually).
You can reconfigure Eclipse so that it uses the config from your Tomcat installation (see Pascal's answer), or to re-enable the manager app - but read the WTP Tomcat FAQ first as there are good reasons for it working the way it does. I don't recall ever needing to do this - the 'Servers' tab in Eclipse lets you deploy/start/stop/debug/configure apps as required.
Im new to Eclipse. I use Tomcat as my run time server, but every time I modified the jsp pages, Eclipse was still displaying the older one. Just wondering how to redeploy the application so the changes can be reflected.

Doubleclick the server instance in question in the Servers view to open its configuration. Now, in the right top you should see a section called Publishing. Open it to verify and configure autopublishing settings.
Eclipse should do that automatically for you.
Otherwise, on the Servers view (Menu Window->Show View->Servers), you can right click on your Tomcat instance and hit "Publish" or "Restart"
Make sure you have the "JST Server Adapters" ("Web, XML and Java EE Development category") feature installed.
Eclipse's publishing functionality requries the project to be a "web project", and in some cases requires additional configurations.
Go to Windows > Preferences > Server > Runtime environments and add your tomcat
Either try using publishing, or (better I think) use the FileSync plugin. There you can tell which folders from your project should be copied (live) to what directory on your machine (the tomcat/webapps/yourapp). With a little more effort the filesync configuration can be made machine independent (only using one parameter as TOMCAT_ROOT), in case you want to check-in the project to a repository where others will use it.
Get the Tomcat plugin. It was nice because you can install Tomcat on your system and then associate your web app with that instance of Tomcat. The plugin will let you stop/start Tomcat and define a server such that when you do a build it knows how to deploy the changes. There may be some newer plugin but the Tomcat plugin worked for me and was fairly simple to install and use. Here is a page from IBM on using Eclipse and Tomcat. Inside that page it points you to the following: http://www.ibm.com/developerworks/opensource/library/os-eclipse-tomcat/
I'm developing on a Ubuntu 8.04 machine using Eclipse Ganymede. I installed Tomcat 5.5 using sudo apt-get install tomcat5.5 tomcat5.5-admin and using an Ant script I deploy my WAR file by copying it to $CATALINA_HOME/webapps.
I then created an Eclipse project and I have it output compiled source in a similar but separate directory structure under $PROJECT_ROOT/target/. I still deploy the WAR file by right clicking on the build.xml and choosing my deploy-war task.
As Tomcat is running as a deamon, automatically started up on booting, I'm not instructing it when to start or exit.
My problems with this setup are:
Using this approach I do not get any output to the Eclipse console, as Tomcat is running under the tomcat55 user and I have a different login and no access to Stdout of tomcat55.
The logging which occurs is also directed to Stdout at the moment, which I find pretty nice during development. But it's not nice when I can't see it. :-)
I don't have any servers under the Server tab and no Run configurations. This makes it impossible for me to use the Debug mode of Eclipse, which otherwise is quite convenient.
What do you think I should do to integrate them and in turn make my development environment much better?
I'd say forget the pre-packaged Tomcat. Grab the apache-tomcat-x.y.z.zip from the site, unzip it somewhere in your $HOME and add a Server to your eclipse workspace, pointing to your local installation of tomcat. Of course you need the j2ee/wtp Eclipse bundle. Works fine on Windows, can't see a reason for it not working on Linux.
Edit: You may have to fiddle with server ports if you have two tomcat installs.
Add Tomcat to the list of Eclipse servers and run your web-app on the server. If you need more details click here.
I never cared about 1 and 2, so I can't really help you with them.
regarding 3:
You don't need any servers under the server tab for debugging to work. Just start tomcat with these environment variables
export JPDA_ADDRESS=8000
export JPDA_TRANSPORT=dt_socket
and configure eclipse accordingly: run - open debug dialog - select remote java app and create a new configuration.
You need eclipse to manage a copy of tomcat, then it can debug it. The clue to the problem was that you have to push deploy-war, this means the files are leaving your development environment and entering an external server. On a properly configured development environment, you only need to save your java file, it will auto-compile and already be on the local tomcat install, which might try to auto reload the web-app, and you can refresh your browser without reloading anything on the server. Look up some more tomcat plugins, there are a few different ways to do this.
If you want to do regular debugging and relaunching of Tomcat apps, you might want to take a look at MyEclipse - it can make things a lot easier.
