Resolution

Ran in <em_home>

./jre/bin/java -jar ./tools/osgi-configurator.cli.jar -d ./product/webview -b ./config/bundles-configuration.txt

which recreated the <em_home>/product/webview/configuration/org.eclipse.equinox.simpleconfigurator and on start up that generated the org.eclipse.core.runtime
org.eclipse.equinox.app, org.eclipse.update directories.

Webview started and was accessible from Chrome.

 

Additional Information

So the logs are filled of java.lang.IllegalStateException: Unable to acquire application service. Ensure that the org.eclipse.core.runtime bundle is resolved and started (see config.ini).
at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:81)

There are number of third-party articles on this. 

You could also try to clear osgi cache . Note that the directions changed with 10.8 SP1

While clearing the cache for some reason the earlier instruction was to clear explicitly the cache from EM_HOME\product\enterprisemanager\configuration except config.ini However this will now give a problem to start EM.

The deletion of org.eclipse.equinox.simpleconfigurator caused this issue.

The org.eclipse.equinox.simpleconfigurator directory contains definition of what OSGi bundles to load and start and when. This should be retained and should not be deleted.

In the event it is also deleted, we can restore functioning by running a command from one level up :

.\jre\bin\java -jar .\tools\osgi-configurator.cli.jar -d .\product\enterprisemanager -b .\config\bundles-configuration.txt
