关于doc转化为pdf，多用户同时访问的问题

[matrix1984]

doc转化为pdf，我是用了一个大家都在用的程序（代码如下，使用Adobe Distiller打印机），好像不支持多用户同时打印，有什么解决的办法吗？

package com.rizon.word2pdf;

import com.jacob.activeX.ActiveXComponent; 
import com.jacob.com.ComThread;
import com.jacob.com.Dispatch; 
import com.jacob.com.Variant;

        private ActiveXComponent wordCom = null; 

        private Object wordDoc = null; 

        private final Variant False = new Variant(false); 

        private final Variant True = new Variant(true); 

        /**

          */ 
        public boolean openWord(String filePath) { 
			//建立ActiveX部件 
			wordCom = new ActiveXComponent("Word.Application"); 
			
			try { 
			    //返回wrdCom.Documents的Dispatch 
			    Dispatch wrdDocs = wordCom.getProperty("Documents").toDispatch(); 
			    //调用wrdCom.Documents.Open方法打开指定的word文档，返回wordDoc 
			    wordDoc = Dispatch.invoke(wrdDocs, "Open", Dispatch.Method, 
			    		new Object[] { filePath }, new int[1]).toDispatch(); 
			    return true; 
			} catch (Exception ex) { 
				ex.printStackTrace(); 
			} 
			return false;
        } 

        /** 
          * 关闭word文档 
          */ 
        public void closeWord(boolean saveOnExit) {
            if (wordCom!=null) {
            	//关闭word文件
            	//Dispatch.call(wordDoc, "Close", new Variant(saveOnExit));
            	wordCom.invoke("Quit",new Variant[]{});
            	//wordCom.invoke("Quit",new Variant[0]);
            	wordCom.release(); //add 2008-07-07
            	wordCom=null;
            	//释放在程序线程中引用的其它com，比如Adobe PDFDistiller
            	ComThread.Release();
            }
        }
