Load model from xml file [message #427382]

Hello,
I have a little Problem with an Eclipse plugin which is based on the EMF
and GMF Frameworks.
EMF will load the models (agreeable with defined metamodels) only if you
need them. For Example I have da File called test.dm. If I open that File
in Eclipse EMF reads the xml File test.dm an put the data into memory.

Now the problem is, that I want EMF to that further.
Example:
I click on a defined button and EMF should then load the files in the
selected project from xml into memory.

Can someone tell me which EMF class is responsible for loading files from
xml into memory?

Thanks for your help
Alex

Generally you'll be using ResourceSet.getResource(<URI>, true) to load
a resource into a resource set. Reading the introductory material
available on the documentation page will help.

hi,
great thanks for your help! I found a documentation about Saving and
Loading EMF Resources.
Only one Problem is left:

The plugin which I have to extend has plugin dependencies like:
org.eclipse.emf_2.3.0

Now changing the code to the effect that emf load the resources further is
not possible because the code is obfuscated.
On the eclipse download page I figured out that the current emf version is
2.5
Can you tell me where I can download the org.eclipse.emf_2.3.0 sources?
Probably I need that because of the compatibility of the current plugin.

Great thanks for your help!!
Bg

Obfuscated?

The downloads page has the zips for all releases. The sources are part
of the SDK (packaged as source plugins):

http://archive.eclipse.org/modeling/emf/emf/downloads/drops/ 2.3.0/R200706262000/
http://archive.eclipse.org/modeling/emf/emf/downloads/drops/ 2.3.1/R200709252135/

Hello,
first of all: thanks again.

Obfuscated means that the plugin-dependency classes are unreadable:
.....
CHECKCAST org/eclipse/core/internal/preferences/DefaultPreferences
PUTFIELD
org/eclipse/core/internal/preferences/legacy/PreferenceForwa rder.defaultsRoot
: Lorg/eclipse/core/internal/preferences/DefaultPreferences;
L3
LINENUMBER 43 L3
ALOAD 0
ICONST_1
PUTFIELD
org/eclipse/core/internal/preferences/legacy/PreferenceForwa rder.notify : Z
L4
.....

Okay I tried to download the emf-sdo-xsd-SDK-2.3.2.zip and extracted the
archieve into my eclipse folder.
After restarting eclipse the problem is still present. I can't
read/edit/debug the code because it looks like above.

Bg
Alex
