If the service should be raised passing arguments through createInstanceWithArgumentsAndContext() and createInstanceWithArguments(), it has to implement the interface com.sun.star.lang.XInitialization. The second service my_module.MyService2 implements it, expecting a single string as an argument.
// XInitialization implementation
void MyService2Impl::initialize( Sequence< Any > const & args )
throw (Exception)
{
if (1 != args.getLength())
{
throw lang::IllegalArgumentException(
OUString( RTL_CONSTASCII_USTRINGPARAM("give a string instanciating this component!") ),
(::cppu::OWeakObject *)this, // resolve to XInterface reference
0 ); // argument pos
}
if (! (args[ 0 ] >>= m_arg))
{
throw lang::IllegalArgumentException(
OUString( RTL_CONSTASCII_USTRINGPARAM("no string given as argument!") ),
(::cppu::OWeakObject *)this, // resolve to XInterface reference
0 ); // argument pos
}
}
