你的jdk版本低了，split方法是jdk1.4的，换个1.4的jdk

网友：kknd97

yuanmeng163(今天我有空):

回答的正确！错误的原因是

无法编译jsp文件，因为string不包括split()方法

换1.4

祝你好运！

网友：acefr

split
public string[] split(string regex)
splits this string around matches of the given regular expression.
this method works as if by invoking the two-argument split method with the given expression and a limit argument of zero. trailing empty strings are therefore not included in the resulting array.

the string "boo:and:foo", for example, yields the following results with these expressions:

regex result
: { "boo", "and", "foo" }
o { "b", "", ":and:f" }

parameters:
regex - the delimiting regular expression
returns:
the array of strings computed by splitting this string around matches of the given regular expression
throws:
patternsyntaxexception - if the regular expressions syntax is invalid
nullpointerexception - if regex is null
since:
1.4

pattern

所以还是下一个jdk吧～
