Who can explain how to write an eclipse based application? I mean an
application from scratch, not an extension of the workbench.
I've found info about IPlatformRunnable, but I don't get it working. If
I check the install.ini I see that by default org.eclipse.ui.workbench
is the application. However in the plugin.xml of that plugin is no
occurence of beeing an extension of
org.eclipse.core.runtime.applications. And that is what I thought was
needed to start as application.
I always get:
java.lang.reflect.InvocationTargetException

application?

thanks, that cleared up some issues for me, but now I have a new problem:
I have following plugin.xml
<?xml version="1.0" encoding="UTF-8"?>
<plugin
id="tk.vanschoren.eclipse.main"
name="Plug-in test project Plug-in"
version="1.0.0"
provider-name="">
class="tk.vanschoren.eclipse.PlugInTest"
>
<runtime>
<library name="main.jar">
</library>
</runtime>
<extension id="main" point="org.eclipse.core.runtime.applications">
<application>
<run class="tk.vanschoren.eclipse.PlugInTest">
<parameter name="optimize" value="true"/>
</run>
</application>
</extension>
</plugin>
And it I use application tk.vanschoren.eclipse.main.main
I seems that the plugin tk.vanschoren.eclipse.PlugInTest is loaded,
because I get debug output from the startup() method.
However, right after that I get an exception in the log file stating
that tk.vanschoren.eclipse.PlugInTest can not be instantiated. How come?
It is already instantiated because I get debug output, or was that
another classloader or so?
below is the output from the log file:
