swftools-0.9.1.exe 和 FlexPaper_1.4.5_flash.zip，工具网上下载。
二、PDF转换SWF文件核心类：

public class DocConverter {
private static final int environment = 1;// 环境1：windows,2:linux(涉及pdf2swf路径问题)
private String fileString;
private String outputPath = "";// 输入路径，如果不设置就输出在默认位置
private String fileName;
private File pdfFile;
private File swfFile;
private File docFile;

public DocConverter(String fileString) {
ini(fileString);
}

/*
* 重新设置 file @param fileString
*/
public void setFile(String fileString) {
ini(fileString);
}

/*
* 初始化 @param fileString
*/
private void ini(String fileString) {
this.fileString = fileString;
fileName = fileString.substring(0, fileString.lastIndexOf("."));
docFile = new File(fileString);
pdfFile = new File(fileName + ".pdf");
swfFile = new File(fileName + ".swf");
}

/*
* 转为PDF @param file
*/

/*
* 转换成swf
*/
private void pdf2swf() throws Exception {
Runtime r = Runtime.getRuntime();
if (!swfFile.exists()) {
if (pdfFile.exists()) {
if (environment == 1)// windows环境处理
{
try {
// 这里根据SWFTools安装路径需要进行相应更改
Process p = r.exec("G:/Program Files/SWFTools/pdf2swf.exe " + pdfFile.getPath() + " -o " + swfFile.getPath() + " -T 9");
System.out.print(loadStream(p.getInputStream()));
System.err.print(loadStream(p.getErrorStream()));
System.out.print(loadStream(p.getInputStream()));
System.err.println("****swf转换成功，文件输出：" + swfFile.getPath() + "****");
if (pdfFile.exists()) {
//pdfFile.delete();
}
} catch (Exception e) {
e.printStackTrace();
throw e;
}
} else if (environment == 2)// linux环境处理
{
try {
Process p = r.exec("pdf2swf " + pdfFile.getPath() + " -o " + swfFile.getPath() + " -T 9");
System.out.print(loadStream(p.getInputStream()));
System.err.print(loadStream(p.getErrorStream()));
System.err.println("****swf转换成功，文件输出：" + swfFile.getPath() + "****");
if (pdfFile.exists()) {
pdfFile.delete();
}
} catch (Exception e) {
e.printStackTrace();
throw e;
}
}
} else {
System.out.println("****pdf不存在，无法转换****");
}
} else {
System.out.println("****swf已存在不需要转换****");
}
}

static String loadStream(InputStream in) throws IOException {
int ptr = 0;
//把InputStream字节流替换为BufferedReader字符流 2013-07-17修改
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
StringBuilder buffer = new StringBuilder();
while ((ptr = reader.read()) != -1) {
buffer.append((char) ptr);
}
return buffer.toString();
}

/*
* 转换主方法
*/
public boolean conver() {
if (swfFile.exists()) {
System.out.println("****swf转换器开始工作，该文件已经转换为swf****");
return true;
}

if (environment == 1) {
System.out.println("****swf转换器开始工作，当前设置运行环境windows****");
} else {
System.out.println("****swf转换器开始工作，当前设置运行环境linux****");
}

try {
//doc2pdf();
pdf2swf();
} catch (Exception e) {
// TODO: Auto-generated catch block
e.printStackTrace();
return false;
}

if (swfFile.exists()) {
return true;
} else {
return false;
}
}

/*
* 返回文件路径 @param s
*/
public String getswfPath() {
if (swfFile.exists()) {
String tempString = swfFile.getPath();
tempString = tempString.replaceAll("\\\\", "/");
return tempString;
} else {
return "";
}
}

/*
* 设置输出路径
*/
public void setOutputPath(String outputPath) {
this.outputPath = outputPath;
if (!outputPath.equals("")) {
String realName = fileName.substring(fileName.lastIndexOf("/"), fileName.lastIndexOf("."));
if (outputPath.charAt(outputPath.length()) == '/') {
swfFile = new File(outputPath + realName + ".swf");
} else {
swfFile = new File(outputPath + realName + ".swf");
}
}
}
}

三、JSP文件，注意引入的几个js文件和FlexPaperViewer.swf文件，其中FlexPaperViewer.swf和jsp文件放在同一目录即可。

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
String paths=(String)request.getAttribute("swfpath");
%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>te</title>

<style type="text/css" media="screen">
html, body { height:100%; }
body { margin:0; padding:0; overflow:auto; }
#flashContent { display:none; }
</style>

<script type="text/javascript" src="<%=basePath %>js/swfobject/swfobject.js"></script>
<script type="text/javascript" src="<%=basePath %>js/flexpaper_flash.js"></script>
<script type="text/javascript">
//
var swfVersionStr = "10.0.0";
//
/* var xiSwfUrlStr = "playerProctInstall.swf"; */
var xiSwfUrlStr = ""; //值可以任意

var flashvars = {
SwfFile : escape("<%=basePath+paths%>"), //swf文件路径（lucene4.6和页面同一个位置）
Scale : 0.6,
ZoomTransition : "easeOut",
ZoomTime : 0.5,
ZoomInterval : 0.1,
FitPageOnLoad : false,
FitWidthOnLoad : true,
PrintEnabled : true,
FullScreenAsMaxWindow : false,
ProgressiveLoading : true,

PrintToolsVisible : true,
ViewModeToolsVisible : true,
ZoomToolsVisible : true,
FullScreenVisible : true,
NavToolsVisible : true,
CursorToolsVisible : true,
SearchToolsVisible : true,

localeChain: "en_US"
};

var params = {

}
params.quality = "high";
params.bgcolor = "#ffffff";
params.allowscriptaccess = "sameDomain";
params.allowfullscreen = "true";
var attributes = {};
attributes.id = "FlexPaperViewer";
attributes.name = "FlexPaperViewer";
swfobject.embedSWF(
"FlexPaperViewer.swf", "flashContent",
"1024", "700",
swfVersionStr, xiSwfUrlStr,
flashvars, params, attributes);
swfobject.createCSS("#flashContent", "display:block;text-align:center;");
</script>

</head>
<body>

<div style="width: 100%;height: 90%; text-align: center;">
<div id="flashContent">
</div>
</div>

</body>
</html>追问额，我的类啥的都没有问题，刚开始的时候是正常的，后来就报了那个错
