Hallo, I cannot get DataSource in Struts.
in my strits-config.xml file is configured: <data-source type="org.apache.commons.dbcp.BasicDataSource"> <set-property property="driverClassName" value="oracle.jdbc.driver.OracleDriver" /> <set-property property="url" value="jdbc:oracle:thin:@chaloupkaj.iccc.cz:1521:ordb" /> <set-property property="username" value="xxx" /> <set-property property="password" value="xxx" /> <set-property property="maxActive" value="10" /> <set-property property="maxWait" value="5000" /> <set-property property="defaultAutoCommit" value="false" /> <set-property property="defaultReadOnly" value="false" /> </data-source>
and in my code: public class TestList extends Action{ HttpServletRequest request = null; ... public int getList() throws Exception { DataSource ds = null; .... try{ try{ // try request object res.append("URI is "+request.getContextPath()+"<br>"); }catch(Exception e){ res.append("something wrong with request!!! <br>"); } try{ ds = this.getDataSource(request); res.append("datasource ok <br>"); }catch(Exception e){ res.append("cannot get datasource!!! <br>"); res.append("Fail: "+e.toString()); }
etc...
and displays: URI is /blabla cannot get datasource!!! Fail. : java.lang.NullPointerException
Is there anything else I must configure, or I badly undestand something else?
Or is there another way to do it better? I am new in Struts, reading manual, I was order some book (Programming Struts) but this book does not deliveder yet...
I cannot use Hibernate for this project becouse data into database will be writen by another way and as I understand hibernate layer should not know about its changes.
Thanks Jiri
