------解决方案--------------------
是不是调用存储过程的格式错了，这是我以前写的参考一下：
Connection conn=DriverManager.getConnection(
"jdbc:oracle:thin:@localhost:1521:orcl",
"wl","u123");
String sql="{call proc4(?,?,?)}"; //call关键字+过程名(问号占位符)
CallableStatement cstmt=conn.prepareCall(sql);
cstmt.setInt(1, 3333);
cstmt.setString(2, "aaaa");
cstmt.setString(3, "M");
cstmt.execute();
