[xwiki-devs] [GSoC][Office Import]how to close a native process in java

Hi, I just finish start up a openoffice server in java code using Process oooProcess = Runtime.getRuntime().exec(oooCommand); The process's name is "soffice". But later the process change its name to "soffice.bin"(or the old "soffice" process end and start a new process named "soffice.bin". I' m not sure). I found that I can't use oooProcess.destroy() to close the "soffice.bin" process. How to close it by java programming? Thanks. Wang Ning
