install and use model Query [message #553008]

Hello,

I'm trying to install the EMF model query plug-in. In the eclipse website
http://www.eclipse.org/modeling/emf/downloads/?project=query

I have download :
* All-In-One Update Site
* SDK (Runtime, Source)
* Runtime
* Examples

// I don't know why there is 4 zip file ..??!!

For the first one (All-In-One Update Site), I unzipped the file which contains a plug-in && feature folders. I opened the plug-in folder. I found 6 zip directories which I extract. then I moved the extracted directories to my eclipse plug-in directory. I did the same for feature folder. That how I learned to install plug-in. I did the same for all downloaded files.
I restarted Eclipse, however when I try :
import org.eclipse.emf.query;
or
org.eclipse.emf.query.conditions.*;

I got an error message : eclipse doesn't recognize the packages and propose to create classes.....

I tried a second method : I unzipped the file and automatically moved it to drop-in folder within eclipse directory. but I got the same result.

Finally, I open help -> install new softwar ->
i have chosen :
- http://download.eclipse.org/releases/galileo
and installed emf queries ...... but still the same problem.

Did I download the wrong files ?? or My plug-in installation method is wrong !!

My objective is to create a model then send queries to obtain information that I need ( example : for a library : number of books with more than 500 pages...)

So far, I haven't found any tutorial or website dealing with model query ?? is there a tutorial which explain how to run these queries??

Thanks in advance

Moadd,

Which version of Eclipse/EMF are you trying to install this into?
Helios, i.e., Eclipse 3.6/EMF 2.6? In general, I'd suggest using the
Helios update site (Help->Install New Software...) rather than unzipping
downloads.

In terms of developing applications using it, I'm not sure if you added
the right bundle dependencies to make the libraries visible. What did
you do to try to make the libraries available in your projects?

hi Ed ,

I use eclipse Galileo but I don't know which version .

In the beginning, I have done nothing to make the library visible,
I just added the plug-in in the appropriate folder.

Normally, Eclipse recognize automatically libraries in the plug-in folder ??!!
I can find EObject... and build EMF project...and I did nothing to make them visible.

as it didn't work, I've added in the build Path an external folder
which contain the org.eclipse.emf.query.* but no result

**********************************************************

I have installed emf.queries from Install New Software .->
but I still can't find
EObjectCondition and athor class in org.eclipse.emf.query

I'm a newbie but I'm sure that this problem could resolved since I actually see the targeted class present in the downloaded folders

best regards

To install it in the IDE. You can normally do that with the update
manager rather than unzipping downloads...

Nothing is visible in a project unless it's added to the classpath.
When building bundles with the PDE, that involves editing the
MANIFEST.MF and adding dependencies....

You're questions seem to be more basic about how to work with PDE and
JDT than about EMF specifically...

You'd normally look for the features in which the are contained, not for
the names of individual classes.

You'll need to read some tutorials about Java development and working
with the Plug-in development environment...
