jsp页面接收到.java页面传来的的变量值，为什么中文就出不来

java页面
public String check3Dmodel(){
    mtlPath = "3Dmodel/";
mtlFileName = imagename+".mtl";
objFileName=imagename+".obj";
System.out.print("objFileName="+objFileName+"  ");
return SUCCESS;

这些是代码，objFileName如果是英文名，像'example1.obj就可以识别，中文的话就不可以，这是为什么呀？
怎么能把Jsp页面的objFileName输出来
