是.看看
XMPP over BOSH.这是一种长期存在的非民意调查技术.从
BOSH specification开始：
This specification defines a transport protocol that emulates the semantics of a long-lived,bidirectional TCP connection between two entities (such as a client and a server) by efficiently using multiple synchronous HTTP request/response pairs without requiring the use of frequent polling or chunked responses.
jbosh是一个开源Java实现. Tigase.org有许多项目,包括BOSH支持,并且似乎主要是Java / GWT. JAXMPP是框架中的Java库,但不清楚它支持哪些功能集.我自己没试过这些.
