Abstract: It is necessary to test and analyze the capability of various distributed objects techniques. To solve the problem to choose preferred plan from a number of distributed objects techniques, some familiar J2EE distributed objects techniques are tested by the high-precision arithmetic of circumference ratio(Bailey-Borwein-Plouffe arithmetic). A lot of data obtained by these tests reflect the capability of computing and starting on these techniques. The significance of these data for application is discussed to design distributed computing system on J2EE.

Key words: computing capability, distributed objects, Web services
