We found that the performance of the Java compiler was nearly as good as that of the C native codes. Hence, a prototype of Java-based DAQ has been developed. At next stage of the Java-based DAQ, new data flow model and new process management model will be investigated, and the message flow model will be enhanced. The management model of a distributed database in the Java-based DAQ will also be studied. Talk at CHEP'97, the International Conference on Computing in High Energy Physics, Berlin, Germany, 7-11 April 1997.
