9 个解决方案
#1
没有这个方法，看看是不是你的包导入错误了
#2
servlet抛出的异常，回调方法出错，仔细检查检查，是不是少东西，还是，写错了。
#3
以前遇到過，好像是包少了還是衝突了。。。
#4
我已经解决了 我用的是5.6.0的jar包，然后他不支持传递地址了，只支持文件，换成5.2.0的jar包就不会报错了
#5

强悍啊；我找了好久；才看到这个方法。确实解决问了。

我也出现了类似的问题，之前我的版本是5.6的，后来换成4.6的jar包，还是报同样的错误。
换成5.2.0真的能搞定么？

感谢#4的XiZhuXi，我换成5.2的包之后解决了。

我换成5.2的包没问题了，但是谁知道用5.6的包应该如何打开PDF？
