Hi guys, I'm new at java and jasper. I have created reports using JasperReports and iReport but have to make my reports more dynamic. Users should be able to select columns that should appear on report. I have tried going thru the article- http://www.ibm.com/developerworks/websphere/library/techarticles/0505_olivieri/0505_olivieri.html but have an error that reads - identify expected at this line :- BufferedWriter writer = new BufferedWriter(new, OutputStreamWriter(outStream)); here is the complete code: import org.apache.velocity.Template; import org.apache.velocity.app.Velocity; import org.apache.velocity.context.Context; import org.apache.velocity.exception.ParseErrorException; import org.apache.velocity.exception.ResourceNotFoundException; import org.apache.velocity.servlet.VelocityServlet; import java.io.BufferedWriter; import java.io.PipedInputStream; import java.io.PipedOutputStream; import javax.servlet.ServletConfig; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.util.Properties; public class VelocityTest extends VelocityServlet { protected Properties loadConfiguration(ServletConfig config) { Properties properties = new Properties(); properties.setProperty(Velocity.FILE_RESOURCE_LOADER_PATH, config.getServletContext().getRealPath("/")); return properties; } public Template handleRequest(HttpServletRequest request, HttpServletResponse response, Context context) { context.put("sql","SELECT * from wcs.tblpayments"); String fieldList[] = {"PAYMENT_NO","WCS_NUMBER","CONTRACT_NO","PAYMENT_INDICATOR","DIVISION_CODE","BENEFICIARY_CODE"," ADVICE_NUMBER"}; context.put("title","testing Velocity"); context.put("$headerString","HEADER"); context.put("fieldList",fieldList); Template template = null; PipedInputStream inStream; BufferedWriter writer ; Thread thread; PipedOutputStream outStream; TemplateCompiler compiler; try { PipedOutputStream outStream = new PipedOutputStream(); BufferedWriter writer = new BufferedWriter(new, OutputStreamWriter(outStream)); // Connect input stream to output stream inStream = new PipedInputStream(outStream); compiler = new TemplateCompiler(inStream); thread = new Thread(compiler); thread.start(); template.merge(context, writer); template = getTemplate("BasicReport.vm"); // tpl = getTemplate("hello.vm"); } catch (ResourceNotFoundException e) { e.printStackTrace(); } catch (ParseErrorException e) { e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); } finally { if (writer != null) { writer.flush(); writer.close(); } } thread.join(); // Get compiled report return (compiler.getJasperReport()); } } any assistance will be greatly appreciated
