Hi,
I have to write a utility that can be run from command line to read all
extension contributions to an extension point. I have looked into headless
RCP and OSGI launchers. All these require eclipse.core.runtime plugin. I
cannot be dependent on core.runtime since we are running our utils on
HP-Itanium. Hence I have to write a Java utility class that can read through
all my jar files (plug-ins) and figure out the extension contributions in
all plugin.xml files and load these classes. Can you point me to the eclipse
code that creates and loads the extension contributions to the Eclipse
registry? Is there some sample code that I can take a look at to read all
plugin.xml files from all jars and create my own registry?
I have many extension points. Is it worthy to convert all these into
Declarative Services and create an OSGI application?
Thanks,
Rashmy

No, it's in the org.eclipse.core.runtime package but it is actually
defined in the equinox.registry bundle. ContributorFactorySimple is
also in the equinox.registry bundle.
Also, check in the thread titled "Using Extension Registry without OSGi"
in eclipse.technology.equinox. It looks like you don't even need the
org.eclipse.osgi bundle, but can reduce the size needed by using the
supplemental one.
It can be done completely with the 3 jars mentioned in this thread and a
java app:
masterToken = new Object();
registry = RegistryFactory.createRegistry(new RegistryStrategy(null,
null), masterToken, null);
Then for each plugin.xml you need to check:
InputStream pluginXmlInput = ...;
String pluginXmlId = ...;
ResourceBundle pluginXmlResources = null; // or dig out the correct one
registry.addContribution(pluginXmlInput,
ContributorFactorySimple.createContributor(pluginXmlId), false,
pluginXmlId, pluginXmlResources, masterToken);

Hi Paul,
I had found a similar code you mentioned in eclipsezone website. But it did
not work for me. Then I tried what you mentioned below, still I have an
issue.
Here is what I did -
I have a plugin called "com.mycompany.base.ui". This contains the below
plugin.xml file-
<plugin>
<extension-point id="testcontributor" name="%ExtPoint.testcontributor"
schema="schema/testcontributor.exsd"/>
<extension
id="MyDataProjectNature"
name="%MyDataProjectNature.name"
point="org.eclipse.core.resources.natures">
<runtime>
<run
class="com.mycompany.base.ui.project.MyDataProjectNature">
</run>
</runtime>
</extension>
</plugin>
Here is the code I had to load the above xml file to the registry-
RegistryStrategy stratergy = new RegistryStrategy(null, null);
IExtensionRegistry registry = new ExtensionRegistry(stratergy, masterToken,
null);
IContributor contrib =
ContributorFactorySimple.createContributor("com.mycompany.base.ui ");
String path = "D:\com.mycompany.base.ui\plugin.xml";
InputStream is = new FileInputStream(path);
registry.addContribution( is, contrib, false, null, null, null );
I get the error -
Error: Could not parse XML contribution for "com.mycompany.base.ui/". Any
contributed extensions and extension points will be ignored.
But when I tried the below test case it worked. I think it is because the
plugin ID "RegistryTest" is in the XML file while the 3.2 plugin.xml that I
have does not have the plugin ID. This is now in the MANIFEST.MF file.
String xmlContribution = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" +
//$NON-NLS-1$
"<plugin id=\"RegistryTest\" version=\"1.0.0\">" + //$NON-NLS-1$
"<extension-point id=\"point1\" name=\"Test extension point\"
schema=\"schema/schema.exsd\"/>" + //$NON-NLS-1$
"<extension point=\"point1\" id=\"extension1\">" + //$NON-NLS-1$
"</extension></plugin>";
IContributor contrib =
ContributorFactorySimple.createContributor("RegistryTest");
RegistryStrategy stratergy = new RegistryStrategy(null, null);
IExtensionRegistry registry = new ExtensionRegistry(stratergy,masterToken,
null);
InputStream is = new ByteArrayInputStream(xmlContribution.getBytes());
registry.addContribution( is, contrib, false, null, null, null );
Is there anything else I have to do to get my plugin.xml file working?
Thanks.

This probably isn't the java statement that you expect:
> String path = "D:\com.mycompany.base.ui\plugin.xml";
You probably want:
String path = "d:\\com.mycompany.base.ui\\plugin.xml";
I was kinda curious, so I took a stab at it. I've attached a java file
that accepts an eclipse/plugins directory and will try and load all of
the plugins into the registry. It tries to load the plugin id and the
localication file from the MANIFEST.MF.
It's the brute-force stupid version, but it appears to work on my
machine. It also doesn't close input streams (not necessary for
addContribution(*), but I didn't check the MANIFEST or ResourceBundle ones).
bash$ java -cp org.eclipse.equinox.registry_3.4.0.v20070820.jar\
:org.eclipse.equinox.common_3.3.0.v20070820.jar\
:org.eclipse.osgi_3.4.0.v20070820.jar\
:check.jar z.ex.registry.CheckRegistry /opt/eclipse330/plugins
This works well with the 3.3.0 jars, and it runs with the 3.2.2 jars
(but not so well).
Later,
PW

I finally got it working. But only after copying the contents of the
InputStream to a string and then sending it as bytes to the
addContribution() method. Maybe there is an issue with the way I am reading
my plugin.xml file

Thanks Paul!
Yes, I did have the string as below. But entered it wrong in the email.
> String path = "d:\\com.mycompany.base.ui\\plugin.xml";
I found that it was an issue with the InputStream I created.
I will also take a look at the sample code that you provided.
Thanks again for your inputs to get my code working!!
