使用JCom将使vcvb能通过COM调用容器当中的EJB，
EJB也可以通过JCom调用远程的Com。
具体功能如下：
JCOM'feature can be summarized as follows:
WebLogic jCOM provides a bi-directional bridge between COM components and Java. Enterprise Java Beans (EJBs) and Java objects can be accessed from COM clients; COM components can be accessed from Java clients.
WebLogic jCOM hides the existence of the data types accessed by the client, dynamically mapping between the most appropriate Java objects and COM components.
WebLogic jCOM supports both late and early binding.
All JVMs are supported.
The machine running the JVM only needs to have the WebLogic jCOM runtime (that is only jCOM.jar) on it. The jCOM.jar file requires no native code, it is pure Java.
No native code is required on the machine hosting the COM Component. Internally, WebLogic jCOM uses the Windows DCOM network protocol to provide communication between both local and remote COM components and a pure Java environment. WebLogic jCOM does, however, support an optional "native mode" which maximizes performance when running on a Windows platform.
The WebLogic jCOM Java runtime (jcom.jar) is approximately 595K in size.
WebLogic jCOM supports event handling. For example, with WebLogic jCOM Java events are accessible from VB using the standard COM event mechanism and also, Java objects can subscribe to COM compnent events.
WebLogic jCOM lets you access COM Components from Java using no authentication, or with the equivalent of Connect level authentication.
EJB也可以通过JCom调用远程的Com。

jboss里面有么？/

to woowindice(黑山老妖):
能谈一谈测试心得吗？
我正想测试，但是水平有限，还没成功，
他的速度比用java直接调用EJB快吗？

好。

特别关注，昨天刚开始研究这个功能！

用web service不好么？

在weblogic7中有这种东西
java2com
com2java
但没测试过
