CustomType - jspBig.type ServerCode has compatibility problem.

[Aikes]

在 tomcat 5.5環境中會顯示下面錯誤訊息：
'for each' statements are only available if source level is 5.0

建議將jspBig.type的ServerCode
29:for (File file:roots) {
30: s+=file.getPath().substring(0,2)+" ";
31:}
取代成
for (int i = 0; i < roots.length; i++) {
s+=roots[i].toString().substring(0, 2)+" ";
}
