Re: [equinox-dev] Using Equinox Hooks for handling application starting?

See https://bugs.eclipse.org/bugs/show_bug.cgi?id=178927 for an enhancement request that is similar to what you require.

The Equinox Hook (AdaptorHook.startFramework method) will not be sufficient for implementing this. You can get the command line by using the EnvironmentInfo service in you hook. You are passed a BundleContext which you could use to get the EnvironmentInfo service. This service has the methods you need to get the command line arguments. But there is no way from the startFramework method to tell the platform not to start the application. When Eclipse RCP is launched it is configured with an application to launch. You still want this application to be configured to launch in case there is no running instance of your application yet. So even though you processed the command line in your adaptor hook and communicated with another running instance the platform will continue to boot and attempt to start your application. At that point your application could determine that a command line was used to communicate with another instance and return immediately. If you already have to enter your application each time then you might as well just put all the TCP client/server logic directly in your application and have it determine whether it should pass the information off to another running instance of your application and return immediately or process the request directly because it is the first running instance of the application.

[equinox-dev] Using Equinox Hooks for handling application starting?





Hello,

We implemented a rcp application which can be started either by clicking the
application file (.exe) or by doubleclicking a file (with a certain
fileextension) on the filesystem. The problem is that we want to handle a
doubleclick on this file by extracting its information and show a dialog in
our application. There are two possibilites: There is already an running
instance or we have to start a new one.

It seems to me that the Equinox Hook can be a friend in this case. Read the
proposed solution under
http://www.ibm.com/developerworks/library/os-eclipse-rcpurl/index.html, I
have the idea to put the uri client into an Equinox hook. Either I can call
the other instance via TCP (and close the new one) or run the current
instance if there is no other instance open.

The problem is now that I have to parse the commandline to get out the
filepath of the file which was used to start our application. Is there a way
to do that in the hook frameworkstart method? How can I close the osgi
platform if there is another instance which can handle the file?

Thanks,
Jens
