Description

In handler, I have methods like

public Vector getData(Vector req)
{
}

public Vector pingHandler()
{
}

On client side, I have code like:
Vector req = new Vector();
req.add("user");
Vector params = new Vector(1);
params.add(req);
client.execute("handler.getData", params);

I always got exception
