Subject Re: Not supported by Basic Datasource
Date Fri, 10 Dec 2010 14:51:43 GMT

1.By normal jdbc process means without implementing any datasource concept in
tomcat  for my project evrything is working fine.It is just when i do
datasource config I'm facing "not supported by basic data source" against a
method that uses a stringbuilder to form a query by retrieving values from a
jsp page dynamically

if (Validation.validate(defRetrivalFields)) {
				defRetrivalFieldsArr = defRetrivalFields.split(",");
				int defRetrivalFieldsArrLen = defRetrivalFieldsArr.length;

				for (int i = 0; i < defRetrivalFieldsArrLen; i++) {

					tempRepresentData = representorMap
							.get(defRetrivalFieldsArr[i]);
					if ("gaGrpCd".equalsIgnoreCase(tempRepresentData)
							|| "taCd".equalsIgnoreCase(tempRepresentData)) {
						formedReqField.append("coalesce(M." + tempRepresentData
								+ ",'-1') AS " + tempRepresentData);
					} else if (("pccDteCreate"
							.equalsIgnoreCase(tempRepresentData)
							|| "pccDteUpdated"
									.equalsIgnoreCase(tempRepresentData) || ("lastUpdate"
							.equalsIgnoreCase(tempRepresentData)))) {
						formedReqField.append("M." + tempRepresentData + " AS "
								+ tempRepresentData);
					} else {
						formedReqField.append("coalesce(M." + tempRepresentData
								+ ",' ') AS " + tempRepresentData);
					}
					orderByField.append("M." + tempRepresentData);

					if (i != (defRetrivalFieldsArrLen - 1)) {
						formedReqField.append(",");
						orderByField.append(",");
					}
					tempRepresentData = null;
				}
			}
			retStr[0] = formedReqField.toString();
			retStr[1] = orderByField.toString();
		}
		return retStr;

2.I tried various  data source possible - <resource
type=javax.sql.DataSource/javax.sql.ConnectionPoolDataSource but to no avail

3.driverClassName="oracle.jdbc.driver.OracleDriver"/"oracle.jdbc.OracleDriver"  

4.The complete java stack trace is while processing the soap message

WARNING: Exception occured in method:searchAgent:Message:Not supported by
BasicDataSource

5.I understand that datasource configuration is a separate entity and does
not depend on the SQL query i have written in my .java file that is fetched
using hibernate but still I want to enquire whether "coalesce" that i'm
using in the dynamic query creation is the culprit because the exception is
occurring when the method returning this processed query is returned as you
can see in the scriptlet

6.the <reqfieldtype,colHeaderRequired etc> and other are values saved into
session from user input page and then requested wherever required

7.I understand u are stressing on code optimization as
(stringbuilder,finally) but my main problem is the functionality that i have
to meet using data source and only after that I can stress upon code
enhancement.i have noted and will implement it.The fact is the project is in
testing environment and i have to implement the datasource and verify again
including final code optimization without which it cannot be tested and put
into production.
