Presents remote servlets collaboration. A method includes: creating a common registry; creating an extended context in response to an external request, wherein the extended context can invoke the resources within the common registry; performing initializing configuration on a plurality of servlets, and registering a plurality of servlets in the common registry, wherein a plurality of servlets being located on different Java virtual machines, or being located in different servlet containers on the same Java virtual machine; and a plurality of servlets collaborate with each other by being invoked through the extended context. It can implement collaboration between servlets located on different virtual machines or even servlets on the same virtual machine but within different servlet containers, because in a converged application service system, not only between HTTP servlets or between SIP servlets but also between HTTP servlets and SIP servlets there is necessity to collaborate.
