关于jacob链接com组件的问题

[六狗回来]

想利用jacob链接spss的com组件：在测试的时候没问题，但是一放到网页上就会出错：错误提示为：
com.jacob.com.ComFailException: Can't co-create object
com.jacob.com.Dispatch.createInstanceNative(Native Method)
com.jacob.com.Dispatch.<init>(Dispatch.java:101)
com.jacob.activeX.ActiveXComponent.<init>(ActiveXComponent.java:58)
org.apache.jsp.citypredict.process_jsp._jspService(process_jsp.java:92)
org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70)
javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:374)

org.apache.jasper.servlet.JspServlet.service(JspServlet.java:267)
javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
而且是一般开始的一两次没错，后来就有错，在网上看到一篇帖子说是要初始化com线程（http://www.chinajavaworld.com/message.jspa?messageID=731691），
否则就会有这个错误，但是我也初始化了的啊，为什么还是有呢。请高手指教。
我的环境配置是myeclipse6.5+tomcat6.0+jacob1.14.3.
想过版本不匹配，换了jacob其他版本也不行。后来发现按照http://www.chinajavaworld.com/message.jspa?messageID=731691上面的源代码放在jsp中执行也还是不可以。
会报content无法找到这样的错误，但是测试的时候是没问题的。
附上部分代码：
ComThread.InitMTA();
ActiveXComponent sC = new ActiveXComponent("Word.Application");
Dispatch spss=(Dispatch) sC.getObject();
String filepath="e://1.sav";
Dispatch.call(spss, "OpenDataDoc", (Object)filepath);
Dispatch doc=Dispatch.get(spss, "documents").toDispatch();
long doc_count=0;
doc_count=Integer.parseInt(Dispatch.get(doc,"datadoccount").toString());
Dispatch.call(doc, "GetDataDoc", (int)(doc_count-1)).toDispatch();
Dispatch datadoc=Dispatch.call(doc, "GetDataDoc", doc_count-1).toDispatch();
ComThread.Release();//

十分感谢！

我在测试下边的代码的时候，会报错误：

Dispatch.put((Dispatch) wordObject, "Visible", new Variant(true));// new Variant(true)表示word应用程序可见
Dispatch documents = objWord.getProperty("Documents").toDispatch(); //documents表示word的所有文档窗口，（word是多文档应用程序）
Dispatch document = Dispatch.call(documents, "Add").toDispatch(); // 使用Add命令创建一个新文档，用Open命令可以打开一个现有文档
Dispatch wordContent = Dispatch.get(document, "Content").toDispatch(); // 取得word文件的内容
Dispatch.call(wordContent, "InsertAfter", "这里是一个段落的内容");//插入一个段落
Dispatch paragraphs = Dispatch.get(wordContent, "Paragraphs").toDispatch(); // 所有段落
int paragraphCount = Dispatch.get(paragraphs, "Count").toInt(); // 一共的段落数
// 找到刚输入的段落，设置格式
Dispatch lastParagraph = Dispatch.call(paragraphs, "Item",new Variant(paragraphCount)).toDispatch(); // 最后一段
Dispatch lastParagraphRange = Dispatch.get(lastParagraph, "Range").toDispatch();
Dispatch font = Dispatch.get(lastParagraphRange, "Font").toDispatch();
Dispatch.put(font, "Bold", new Variant(true)); // 设置为黑体
Dispatch.put(font, "Italic", new Variant(true)); // 设置为斜体
Dispatch.put(font, "Name", new Variant("宋体")); //
Dispatch.put(font, "Size", new Variant(12)); //小四
Dispatch.call(document, "SaveAs", new Variant("D:abcde.doc")); // 保存一个新文档
ComThread.Release();//
可是不通过网页，单独测试是可以的，那位大虾知道是为啥么？谢谢！

如果跑的是tomcat容器　尝试将dll放放到bin下
