Drilldown hyperlinks are broken in HTML report.

Hello,

I am rendering an intermediate BIRT report document into an HTML report but the drill down hyperlinks are broken. However, the same BIRT document opened in frameset? works fine.

The generated drill down hyperlink in HTML report is:
http://localhost:8080/documents/run?__report=/C:/apache-tomcat-6.0.18/bin/report/reports/ApplicationRTM_L2.rptdesign

Whereas the drill down hyperlink should be:
http://localhost:8080/run?__report=report/reports/ApplicationRTM_L2.rptdesign

Could anybody please tell me how do I correct drill down hyperlink when I render the report in to an HTML document:

The following code I am using for generating an HTML report:

IRenderTask renderTask = BirtEngine.getReportEngine().createRenderTask(document);
HTMLRenderOption options = new HTMLRenderOption( );
options.setOutputFormat("html");
String imageDir = ****;
options.setBaseImageURL("****"+imageDir+"/");
options.setImageDirectory(imageDir);
options.setSupportedImageFormats( "PNG;GIF;JPG;BMP;SWF");
//options.setSupportedImageFormats( "PNG;GIF;JPG;BMP");
ByteArrayOutputStream osr = new ByteArrayOutputStream();
options.setOutputStream(osr);

options.setImageHandler(new HTMLServerImageHandler());
renderTask.setRenderOption(options);

renderTask.render();
renderTask.close();

Thanks,
SKV

You need to set the base url. This is alot like the image base url:

HTMLRenderOption options = new HTMLRenderOption();
options.setOutputFileName("output/resample/master.html");
options.setOutputFormat("html");
options.setHtmlRtLFlag(false);
options.setEnableAgentStyleEngine(true);
options.setEmbeddable(true);
options.setBaseURL("http://localhost:8080/myurltomyrunservlet");
options.setActionHandler(new HTMLActionHandler());
task.setRenderOption(options);
task.run();
task.close();

Also look at the drill down defintion to see if the directory for the detail report is pathed or just a report name.

You can also implement your own action handler that builds the drill through url any way you want it.

Just implement IHTMActionHandler eg MyActionHandler implements IHTMLActionHandler

ande set it in the render options. like

options.setActionHandler( new MyActionHandler() );

Thanks Jason for the information. 
 
After adding base url the first part of URL is correct now. But however the second part of URL 
i.e., run?__report=%2FC%3A%2Fapache-tomcat-6.0.18%2Fbin%2Freport%2Freports%..., is still wrong. It should be 
run?__report=report%2Freports/... . 
 
I am wondering what setting is appending extra "%2FC%3A%2Fapache-tomcat-6.0.18%2Fbin%2" to access detailed report. 
 
In the drill down definition the detail report is just a report name.

Can you post the master report?

Hi Jason, 
 
Sorry, I cant post you master report, I am not permitted to do so. 
 
However, I am seeing a strange problem with drill down URL from an HTML file. 
 
The URL generated is based upon the location of the HTML report file. 
 
for example: If I keep the HTML in WEBROOT/documents dir, the drill down URL gets generated localhost:8080/documents/run?.... 
 
whereas if I put HTML in WEBROOT/ the URL get generated is: localhost:8080/run? 
 
The problem here is the detail report shows up only when the drill down URL is localhost:8080/run?. No report is displayed if the URL is localhost:8080/documents/run?. There is not error on server or report engine. 
 
I am not sure why is this happening? AM I missing anything on BIRT deployment side? 
 
Thanks and regards,

Are you setting the base url?
options.setBaseURL("http://localhost:8080/myurltomyrunservlet");

No, I am not setting it, I do not want to hard code it. The application can be accessed through http and https. Also, the HTML rendering takes place in background so we cant predict how user is going to access it.

The only I see then is to implement your own Action handler.
