Hi everybody,
I am looking to add my custom RepositoryService to Jaspersoft Studio. I have implemented a custom protocol using a new URLStreamHandlerFactory. My code works just fine when use it in my application, although I would like to have the same functionality in the workbench at design time.
CustomRepositoryService.java
import java.io.IOException; import java.io.InputStream; import java.net.URL; import java.net.URLConnection; import java.net.URLStreamHandler; import java.util.Arrays; import net.sf.jasperreports.engine.DefaultJasperReportsContext; import net.sf.jasperreports.engine.JasperFillManager; import net.sf.jasperreports.engine.JasperReportsContext; import net.sf.jasperreports.engine.SimpleJasperReportsContext; import net.sf.jasperreports.repo.DefaultRepositoryService; import net.sf.jasperreports.repo.RepositoryService; public class CustomRepositoryService extends DefaultRepositoryService { public CustomRepositoryService(JasperReportsContext parent) { super(parent); setURLStreamHandlerFactory(proto -> { return "myproto".equals(proto) ? new URLStreamHandler() { @Override protected URLConnection openConnection(URL u) throws IOException { return new URLConnection(u) { @Override public void connect() throws IOException { // noop } @Override public InputStream getInputStream() throws IOException { // do custom stuff to retrieve the data stream return super.getInputStream(); } }; } } : null; }); } }
Usage example snippet
SimpleJasperReportsContext ctx = new SimpleJasperReportsContext(); CustomRepositoryService repositoryService = new CustomRepositoryService(DefaultJasperReportsContext.getInstance()); ctx.setExtensions(RepositoryService.class, Arrays.asList(repositoryService)); JasperFillManager fillManager = JasperFillManager.getInstance(ctx); JasperPrint jasperPrint = fillManager.fill(jasperReport, parameters);
JRXML example snippet
<!--[CDATA["myproto:/images/logo.jpg"]]-->
Is it possible to attach this solution to the Jaspesoft Studio?
Is there a better way to achieve the same goal?
Any help would be much appreciated!
Best Regards,
Zsolt

Hi anybody,
I managed to make it work as an Extension based on this javadoc
http://jasperreports.sourceforge.net/api/net/sf/jasperreports/extensions/package-summary.html
