java调用第三方dll出错，求帮助。。

[ffsdp]

dll是对ic卡操作的，delphi写的，里面的一个函数
function icmake(port:integer;userid:string;userpw:string;price:real;):integer;
我用jnative调用它
System.loadLibrary("makecard");
JNative jn = new JNative("makecard","icmake");
jn.setRetVal(Type.INT);
jn.setParameter(0, Type.INT, "2");
jn.setParameter(1, Type.STRING, "user");
jn.setParameter(2, Type.STRING, "password");
jn.setParameter(3, Type.FLOAT, "0");
jn.invoke();
System.out.println(jn.getRetVal());
出现下面大情况，请问这是怎么回事呢?

C:\Documents and Settings\Administrator\Workspaces\MyEclipse 8.5\dlltest\hs_err_pid3516.log 这里面看看什么错。 另外建议用JNA，这个相对更简单
