db2 Invalid parameter: Unknown column name SERVER_POOL_NAME . ERRORCODE=-4460, SQLSTATE=null - jdbc

Question

I am using SQL 'select' to access a db2 table with schemaname.tablename as follows:
select 'colname' from schemaname.tablename
The tablename has 'colname' = SERVER_POOL_NAME for sure . yet I get the following error :
"Invalid parameter: Unknown column name SERVER_POOL_NAME . ERRORCODE=-4460, SQLSTATE=null"
I am using db2 v10.1 FP0 jdbc driver version 3.63.123. JDBC 3.0 spec
The application is run as db2 administrator and also Windows 2008 admin
I saw a discussion about this issue at : db2jcc4.jar Invalid parameter: Unknown column name
But i do not know where the connection parameter 'useJDBC4ColumnNameAndLabelSemantics should be set ( to value =2)
I saw the parameter should appear in com.ibm.db2.jcc.DB2BaseDataSource ( see: http://publib.boulder.ibm.com/infocenter/db2luw/v9r5/index.jsp?topic=%2Fcom.ibm.db2.luw.apdv.java.doc%2Fsrc%2Ftpc%2Fimjcc_r0052607.html)
But i do not find this file on my DB2 installation . maybe it is packed in a .jar file
Any advice ?

There is a link on the page you're referring to, showing you the ways to set properties. Specifically, you can populate a Properties object with desired values and supply it to the getConnection() call:
String url = "jdbc:db2://host:50000/yourdb";
Properties props = new Properties();
props.setProperty("useJDBC4ColumnNameAndLabelSemantics", "2");
// set other required properties
Connection c = DriverManager.getConnection(url, props);
Alternatively, you can embed property name/value pairs in the JDBC URL itself:
String url = "jdbc:db2://host:50000/yourdb:useJDBC4ColumnNameAndLabelSemantics=2;";
// set other required properties
Connection c = DriverManager.getConnection(url);
Note that each name/value pair must be terminated by a semicolon, even the last one.
