I create a web based project with eclipse and the application server is Tomcat and everything is OK, but I have a few files in specific folder that I should change the content of these files with another development environment that it's created by myself, after I change the file's the eclipse doesn't refresh the file and therefore I must go to eclipse, select the folder, press f5 to refresh it.
My Question is that, How can I refresh that specific folder without doing these steps, for example does eclipse have specific API for refresh the folder?
You can use IResource.refreshLocal to refresh a folder (or file).
One way to use this:
IWorkspaceRoot root = ResourcesPlugin.getWorkspace().getRoot();
IContainer folder = root.getgetContainerForLocation(new Path("folder path"));
folder.refreshLocal(IResource.DEPTH_INFINITE, null);
This must be run in an Eclipse plugin.
Update:
You can tell Eclipse to refresh automatically in Preferences > General > Workspace by checking the 'Refresh using native hooks or polling' option.
There is no way to force a refresh from a program external to Eclipse.

In my Eclipse preferences, I have "Refresh using native hooks or polling" selected.
If I make a change to a Java file outside of Eclipse, the project that contains that Java file automatically refreshes and rebuilds that file as it should. However, if I make a change to a file under src/main/resources/... from an external editor, it is not automatically refreshed. I have to select the project and press F5 to get it to refresh.
Is there a way to configure Eclipse to automatically refresh any resources under src/main/resources?
In Eclipse
Run > External Tools > External Tools Configuration
Create a new Program configuration Point the location to an exe that is very fast
On the Refresh tab, choose Refresh Resources upon completion, The Entire Workspace
On the Build tab, deselect Build before launch
I have a folder containing images under WebContent. If I copy file 1.jpg to images using Windows Explorer, it won't show on my webpage:
document.getelementById("image1").src = "./images/1.jpg"
However, if I right click the project in Eclipse, refresh, then everything works.
How do I remove the need to refresh the project? The images are supposed to be generated by another program dynamically
If something outside of Eclipse modifies the workspace it is always necessary to do a refresh.
However you can configure Eclipse to do this automatically in Preferences > General > Workspace. Check the 'Refresh using native hooks or polling' option.
If the program generating the images is an Eclipse plugin it can use Eclipse APIs to create the files or do the refresh (a normal program cannot do this).
If you run the program using Eclipse Run External Tool configuration there is a Refresh tab that will let you set up the refresh to do when the program terminates.
I currently use emacs to edit .java files and run eclipse.
Eclipse doesn't automatically recognize modified files, so I often end up running unmodified application.
I wonder if there exists a shortcut to refresh all the modified files in eclipse.
Perhaps you want to check Preferences > General > Workspaces > Refresh using native hooks or polling. You can see that the eclipse refreshes the file you edit with external editor (like vi, emacs, etc) when you check the option.
On the project explorer you need to select the project(s) that you want to refresh and then click on File->Refresh or hit F5.
I manually copy needed jar files into my project lib folder. Then, I try to add them to build path via "configure build path option". If i choose "add jar", then the lib folder does not show up in the "to choose from" list. So, I am forced to use "add external jars" option instead. But, that option does not make the jars a part of the project even though they lie in the lib folder. After I restart eclipse 2-3 times, the jars are magically integrated into my project.
Why is eclipse behaving this way ? Why can't I do this easily ?
Please help me.
By default, Eclipse dose not detect file change which come from outside, like copy a jar file in lib folder manually.
So after you copied jar files, you have to refresh the project by pressing F5 while selecting your lib folder. I believe that's why eclipse cannot found your jar files.
If you want to solve this problem once for all, you can active "Refresh using native hooks or polling" via
Window -> Preference -> General -> Workspace
However, this might slow down Eclipse if you have a big project with many many files.
UPDATE
As Bananeweizen mentioned, instead of doing all the copied from outside of Eclipse, you can also copied those file into Eclipse, Package Explorer View for example. This way Eclipse will detect and refresh folder automatically.
The way I was taught to add external jars to an eclipse project is to drag the jar file from explorer into the lib folder in eclipse and then on the dialogue eclipse responds with is choose the copy to option and eclipse imports the jar file and copies it to the lib location at the same time.
I'm new to programming and IDEs. I never understood the concept of a workspace in Eclipse, and I don't understand it in Aptana.
With Eclipse I just put it into my web root. Not sure if that's the way to go?
Can someone explain what a workspace is and where it should go? And if not in the web root, then how do I launch a PHP page from within the EDI?
Thanks!
An Eclipse workspace is a directory where (generally) all of the files you are working on live and that stores all of the state (like preferences and such) for a single user of Eclipse. So when you create projects, they are located in the workspace. The workspace has some metadata files that control how Eclipses behaves for you.
Eclipse keeps a representation of the workspace internally, which means the workspace can get out of sync with the underlying files. To sync them up, do a right-click Refresh in the Package/Project Explorer.
Usually the workspace goes into some directory relative to your home directory, since it's private to each developer.
Workspaces are like folders where the project's files are.
When you have a local web server you could set the workspace to a new folder in the servers directory (or web root when the project should be in the main directory!) . If you want to add a new PHP-file in Aptana studio 3 just right click the workspace and select add new file (or sth. like that). After that you will be able to enter a file-name and it's gonna be saved in the workspace (folder). But of course you can also work without workspaces, just create the the PHP-File and edit it with Aptana.
