[news.eclipse.technology.equinox] Re: Equinox Transforms

["Kathir" <kathir@xxxxxxxxxxx>]

2. I resolved the problem of launching it from inside eclipse, i had to 
import the org.eclipse.osgi project into the workspace. Otherwise it wont 
work.

But i got into a different problem now, Now i get a ClassNotFoundException 
from inside the transforms extension class.

 1. com.comp.product.transforms
 2. com.comp.product.diagnostics

I have a PluginTransformingBundleFileWrapperFactoryHook which implements 
BundleFileWrapperFactoryHook,HookConfigurator, AdaptorHook

public BundleFile wrapBundleFile(BundleFile bundleFile, Object content, 
BaseData data, boolean base)

throws IOException

{

if (m_startLevelManager != null && m_startLevelManager.getStartLevel() >= 1)

{

if (m_loginClass == null)

{

try

{

ClassLoader classLoader = getClass().getClassLoader();

m_loginClass = classLoader.loadClass(m_loginProperty);

ILogin login;

System.out.println("Calling the Login module");

login = (ILogin) m_loginClass.newInstance();

// The actual rights loading from a login

// implementation.

m_rightsList = login.login();

login = null;

}

catch (Exception e)

{

e.printStackTrace();

System.err.println("RCP-Auth: Couldn't call the " + "ILogin.login 
method.\nEclipse will now exit.");

// System.exit(1);

}

}


return new PluginTransformBundleFile(getContext(), data, bundleFile);

}

return null;

}





PluginTransformBundleFile.java



/**

* Returns BundleEntry at path.

*

* @param path

* The file path.

* @return The original bundle entry, or a PluginTransformBundleEntry 
instance.

*/

@Override

public BundleEntry getEntry(final String path)

{

final BundleEntry original = m_delegate.getEntry(path);

if (m_data.getBundle() == null || path == null || original == null)

{

return original;

}


try

{

if (path.equals("plugin.xml"))

{

return new PluginTransformBundleEntry(original, original.getInputStream());

}

}

catch (IOException e)

{

System.err.println(this.getBundleContext() + "#" + 
this.getClass().getCanonicalName() + ": "

+ "Couldn't create " + PluginTransformBundleEntry.class.getCanonicalName() + 
" for file " + path);

}


return original;

}

I get a ClassNotFoundException for PluginTransformBundleEntry when i run in 
debug mode. In normal mode nothing happens, it just didnt do the transform. 
i 
have -Dosgi.framework.extensions=com.comp.product.transforms,com.comp.product.diagnostics 
in the run configurations vm arguments.

I am struck with this now.
