本文探讨了在Nokia6120设备上使用Java进行网络连接时遇到的SymbianOS错误-11的问题。该错误通常表明尝试重复打开已存在的连接。文章提供了具体的解决方案，即在建立新连接前先断开已有连接。

public void myFunct()
    {
        StreamConnection conn = null;
        InputStream is = null;

        try{
            conn = (StreamConnection)Connector.open(url);
            is = conn.openInputStream();

        }catch(Exception e){}
    }

在nokia 6120 上运行有时会报java.io.IOException SymbianOS error = -11的错误，搜了google，原因如下：
error = -11：
An object already exists.
An object of some name/type is to be created, but an object of that name/type already exists.

That means your previously opened connection is still open and you are again trying to open the same connection.
Better you make a method which disconnect the connection and make a call to this method just before you gonna create/open the new connection. Kindly try to implement this and have a look over if the underlined issues get resolved.
