How do I add imageJ/fiji libraries to my project build path in Eclipse?

[Number5]

Hi, I'm new to ImageJ and I would like to know how to add the library to my build path (to use the functionality in my code)?

I've found a lot of documentation about creating plug-ins, but found next to nothing about using it as a third-party library. From what I have seen, it looks like I should add the ij.jar file to the build path (like with other libraries), but something won't let me and I was wondering if someone could tell me what i'm doing wrong?

Outside of Eclipse I can locate the jar file by right-clicking on the application and selecting 'show package contents', however in Eclipse I click on 'add external jars' and try the same thing, but only get the option 'quick look'. I can't seem to get to the jar file.

I've also tried dragging the file from my hard drive into eclipse and copying the file without any luck. I'm running Mac OSX Mountain Lion and Eclipse Juno.

Can anyone tell me what I'm doing wrong? or if you have another way of adding the library to a project please let me know!

Thanks!

When you add an external .jar file in Eclipse you should get a file
browser to search for the file you want to add. What is exactly the
problem you are encountering?

Best,

José.

Hi,

Thanks for replying. Yes I get the file browser, but i don't know how to navigate to the .jar file as it seems to be located inside the ImageJ application. The Eclipse file browser won't let me access this!

However, in a file browser outside Eclipse (in finder) I can access the .jar file by right clicking on the ImageJ application icon and selecting 'show package contents'. I can't do this in Eclipse! It won't give me the option!

I would just like to know how to access the .jar file (when it is located inside the application)? Or if there is another way to add it to my build path?

Thanks

I think I understand what is happening. The ImageJ ij.jar file is
placed inside the ImageJ installation directory. You have to search
for that folder in your directory tree. If you are using Windows, I
think the default installation path goes along the lines of C:\Program
Files\ImageJ, so try that or similar combinations.

Best,

José.

Yup, that is the problem! But I don't know how to access the installation
directory inside the Eclipse file browser?

I'm using a Mac!! Do you know the Mac equivalent? I've tried right-clicking.

Thanks

Just type in imagej.jar in spotlight. It is not found within the actual
program as you're suggesting, it's just in a folder. In fact, if I'm not
mistaken, for Mac you just downloaded imagej.zip and , it. The unzipped
folder is just named imagej and contains imagej.jar, but it's location is
based on where you downloaded it to.

Most importantly, the problem you think you're having is not an issue. It's
not hidden within a program, it's in a folder that is readily navigatable
via eclipse as well as finder. Just use spotlight and find the location on
your mac

Another option is to download the ImageJ .zip file and extract the
.jar file from there. If you are going to use it as a library, that
option is as good as using the ij.jar file from your current
installation.

Best,

José.

One of the first things I did was try and find it through spotlight! It did not find ij.jar. I tried a lot of keywords and even searched through all .jar files.

I got the zip, unzipped it. I found ij.jar (outside eclipse) by right-clicking the application icon (the microscope) and selecting 'show package contents'. After this it was located in contents/resources/java I don't know how to access this in Eclipse as the option 'show package contents' is not there!

Like I said, spotlight didn't work. It is not readily navigable for me, although it might be for others.

Hi

I don't know Eclipse well, but adding the ij jar file should be done by "open" or "add", navigating to ImageJ app, which than is shown as a folder (in fact apps are folders) and there you find the jar file similar as with "show package content".

I know that I can navigate into the app folder because I did so outside Eclipse. There might be something different about my settings or i'm missing something obvious! Once I click the application, I can't go further.

But thanks for all your help! I found a solution by dragging the .jar file from the file browser in finder into the file browser in Eclipse! I was trying to drag it all sorts of places before, but obviously didn't try dragging it from browser to browser till now.

The file open dialogs on Mac don't let you access the package contents
as you can do in Finder.
As a workaround, you can Alt-Cmd-Drag any folder (e.g. Fiji.app/jars)
out of the .app package into a normal, accessible folder on your disk.
This will create a symlink/alias that is accessible also via the file
chooser dialogs.

Hth,
Jan

On that note, my apologies, as I was clearly totally wrong

To add a JAR file that is outside your Eclipse project simply use the menu

Project -> Properties -> Java Build Path -> Libraries -> Add External Jars...

and navigate to the desired Jar file. This lets you add Java libraries from anywhere in your file system.

Thank you so much :) I spent ages trying to work it out. I'm sure this will help others as well.

Hi Number5,

- In Finder, right-click the ImageJ application
- Choose "Show package contents"
- Navigate into Contents, Resources, Java
- Click on ij.jar
- Press Command+C to copy the file
- Click your Desktop
- Press Command+V to paste
- Now in Eclipse, navigate to your Desktop and use that copy of ij.jar

HTH,
Curtis

Hi,

I think you misunderstood the problem. I know how to add a .jar file to my project, but the problem was that I could not locate the file in the Eclipse file browser due to its location (inside the application contents folder). Jan Eglinger wrote above that on a mac it is not possible to access this location in file open dialogues. However, I was offered many solutions that are posted above. Thanks anyway! :)
