java項目調用其他項目main方法

需求是這樣子滴，因爲我們要部署到linux系統上，用到其他項目的某個main方法，然後傳時間過去，返回數據

        String start = request.getParameter("start");
        String temp = PropertyUtil.getProperty("D5000path");//讀取配置文件中的路徑
        start = start.replaceAll(" ", "\" \"");//時間中間有空格，這樣才能正常傳過去
        Process p =Runtime.getRuntime().exec(temp+" "+start);//調用其他項目的main方法
        InputStream in = p.getInputStream();
        InputStreamReader isr = new InputStreamReader(in);
        BufferedReader br = new BufferedReader(isr);
        String line ="";
        while ((line = br.readLine())!=null){
            System.out.println(line);
        }

配置文件的路徑

D5000path = java -classpath D://workspace//was//bin com.was.action.HelloWorld

因爲還沒部署，用的就是windows下的路徑，當然我是很簡單的，如果是複雜的，要將用到的jar也寫進去，參考如下：

<entry key="D5000path">java -classpath E:\WorkSpace\D50001\classes;E:\WorkSpace\D50001\lib\axis-ant.jar;E:\WorkSpace\D50001\lib\activation.jar;E:\WorkSpace\D50001\lib\axis-schema.jar;E:\WorkSpace\D50001\lib\axis.jar;E:\WorkSpace\D50001\lib\c3p0-0.9.1.2.jar;E:\WorkSpace\D50001\lib\commons-discovery-0.2.jar;E:\WorkSpace\D50001\lib\commons-logging-1.0.4.jar;E:\WorkSpace\D50001\lib\dbutils.jar;E:\WorkSpace\D50001\lib\hamcrest-core-1.3.jar;E:\WorkSpace\D50001\lib\jaxrpc.jar;E:\WorkSpace\D50001\lib\jta.jar;E:\WorkSpace\D50001\lib\log4j-1.2.15.jar;E:\WorkSpace\D50001\lib\mail.jar;E:\WorkSpace\D50001\lib\ojdbc14.jar;E:\WorkSpace\D50001\lib\wsdl4j-1.5.1.jar; com.eflow.bpa.BpaMain</entry>
