有个日本人做的开源包叫JCOM是一个java与COM的桥以前用过操作EXCEL打印的COM接口package test;import jp.ne.so_net.ga2.no_ji.jcom.ReleaseManager;
import jp.ne.so_net.ga2.no_ji.jcom.excel8.ExcelApplication;
import jp.ne.so_net.ga2.no_ji.jcom.excel8.ExcelWorkbook;
import jp.ne.so_net.ga2.no_ji.jcom.excel8.ExcelWorkbooks;
import jp.ne.so_net.ga2.no_ji.jcom.excel8.ExcelWorksheet;
import exception.ReportPrintException;public class TestCom {
    private String filename;    public TestCom() {    }    public void setPrintFilename(String file) {
        filename = file;
    }    public boolean print() throws ReportPrintException {
        boolean success = false;
        if (filename != null) {
            ReleaseManager rm = new ReleaseManager();
            try {
                ExcelApplication excel = new ExcelApplication(rm);                ExcelWorkbooks xlBooks = excel.Workbooks();
                ExcelWorkbook xlBook = xlBooks.Open(filename);
                ExcelWorksheet xlSheet = excel.ActiveSheet();
                excel.Visible(true);
                xlSheet.method("print",null);
                xlBook.Close(false, null, false);
                excel.Quit();                success = true;
            } catch (Exception e) {
                e.printStackTrace();
                throw new ReportPrintException(e.getMessage());
            } finally {
                rm.release();
            }
        }
        return success;
    }
    
    public static void main(String[] args){
        TestCom com=new TestCom();
        com.setPrintFilename("C:\\aaa.xls");
        try {
            com.print();
        } catch (ReportPrintException e) {
            e.printStackTrace();
        }
