jsf 2 - getting null value in username and password from database -

database=db_jsf table=tbl_users fields=id,uname, pword when ever seek run doesn't values form database cannot match database name input text.

public void dbdata(string uname){ try{ class.forname("com.mysql.jdbc.driver"); con = drivermanager.getconnection("jdbc:mysql://localhost:3306/db_jsf","root","root"); ps = con.createstatement(); sql_str="select * tbl_users uname ('" + uname + "')";// rs=ps.executequery(sql_str); rs.next(); dbusername=rs.getstring(2).tostring(); dbpassword=rs.getstring(3).tostring(); }catch(classnotfoundexception ex){ system.err.print("class not found in getconnection"+ex.getmessage()); }catch(exception e) { //e.printstacktrace(); system.out.println("exception error"+e); } } public string checkvaliduser(){ dbdata(username); system.out.println("username ::"+dbusername); system.out.println("password ::"+dbpassword); if(username.equals(dbusername) && password.equals(dbpassword)) { system.out.println("valid data"); homecoming "valid"; } else { system.out.println("invalid data"); homecoming "invalid"; } }

these codes when ever seek come in username , password prints out username:null password:null

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
