如何通过java代码直接打开自己主机上的一个Excel表格

如何通过java代码直接打开自己主机上的一个Excel表格，不是表格中的一些数据而是整个Excel表格都要打开！

不知道是不是这个意思，看下面的代码
[code="java"]
import java.io.*;

public class ExecuteCommandBean {

private String command;
private Process process;
private String responseText;
private InputStream is;
private InputStreamReader isr;
private BufferedReader br;

public ExecuteCommandBean(String command) {
    this.command = command;
}

public void execute() throws Exception {
    Runtime runtime = Runtime.getRuntime();
    Process process = runtime.exec(command);
    process.waitFor();

    is = process.getInputStream();
    isr = new InputStreamReader(is);
    br = new BufferedReader(isr);

    StringBuffer buffer = new StringBuffer();
    String line = null;

    while( (line = br.readLine()) != null ) {
        buffer.append(line + "\n");
    }

    responseText = buffer.toString();
}

public String getResponseText() throws Exception {
    return responseText;
}

public void close() {

    try {
        if(br != null) { br.close(); }
    } catch(Exception e) {
        e.printStackTrace();
    }

    try {
        if(isr != null) { isr.close(); }
    } catch(Exception e) {
        e.printStackTrace();
    }

    try {
        if(is != null) { is.close(); }
    } catch(Exception e) {
        e.printStackTrace();
    }

    try {
        if(process != null) { process.destroy(); }
    } catch(Exception e) {
        e.printStackTrace();
    }
}

public static void main(String[] args) throws Exception {
    //windows下
    String command = "excel c:/books.xls";
    ExecuteCommandBean ecb = new ExecuteCommandBean(command);
    ecb.execute();
    System.out.println(ecb.getResponseText());
}

}
