这个取网页中图片的正则表达式为什么会报错？
取一个在线编辑器送来的html内容中的图片地址，正则如下，通过正则检测工具检查，可以取出图片的地址，但在Resin中却报错，百思不得其解，望明白的指点一下。
String content = request.getParameter( "content ");
Pattern pat = Pattern.compile( "http:\/\/(\w+\.)+(net|com|cn|org|cc|tv)(\S*\/)(\S)+\.(gif|jpg|png|bmp) ", Pattern.CASE_INSENSITIVE );
Matcher mat =pat.matcher(content);
while(mat.find())
{
out.print(mat.group()+ " <br> ");
}
报错代码如下：
500 Servlet Exception

Pattern pat = Pattern.compile( "http:\/\/(\w+\.)+(net|com|cn|org|cc|tv)(\S*\/)(\S)+\.(gif|jpg|png|bmp) ",

[解决办法]
Pattern pat = Pattern.compile( "http:\/\/(\w+\.)+(net|com|cn|org|cc|tv)(\S*\/)(\S)+\.(gif|jpg|png|bmp) ", Pattern.CASE_INSENSITIVE );
代码放在一行输入或者增加上续行符号
