generate hyperlinks in my report using servlets.

I'm running BIRT and have written my own servlet which processes a 
report request and renders it to the output stream using the report engine 
API. The problem I'm having is that hyperlinks do not get rendered as 
links at runtime. If I create a hyperlink in a label or create a 
drill-through hyperlink, at design time in preview mode the link gets 
rendered correctly and works as expected. When I execute the same report through my custom servlet, the hyperlink 
text gets rendered but it is not rendered as a link. 
 
At runtime, this would need to be my servlet context. Is there a way to set the context to be used for hyperlinks at runtime 
say i display <a class='bbc_url' href='http://www.google.com'>Google</a> as my text of a particular column,when i click on it.i need to open a browser with the desired link. 
 
You can reply me at <a href='mailto:' title='E-mail Link' class='bbc_email'>pradeep.sreenivas@gmail.com</a> as well. 
 
Thanks in advance 
 
Any thoughts or help with this would be greatly appreciated.

Hi PraddepKS,

So your hyperlinks arene't working at all when run on the web viewer?

Hi PraddepKS,

Which emitter are you using to generate report output using the Report Engine API? Can you post a sample snippet of that code?

Hi vdodson..
Thanks for the immediate reply.I was out for a while.So could nt respond to you immediately.

here is the code snippet.

I tried

HTMLRenderOption options = new HTMLRenderOption();
options.setImageHandler(new HTMLImageHandler());
options.setActionHandler(new ViewerHTMLActionHandler());

This is all i am doing to render the link.but it appears as a plain text.

I also tried setting the action handle in my rptdesign structure in this way before doing the above snippet.

DataItemHandle abc= reportDesignHandle.getElementFactory().newDataItem(columnName);
abc.setAction(StructureFactory.createAction());
abc.setResultSetColumn(columnName);
abc.getActionHandle().setLinkTypeDesignChoiceConstants.ACTION_LINK_TYPE_HYPERLINK);
CellHandle hyperlink = (CellHandle) detailRow.getCells().get(hyperlinkIndex);

is this is the right way of setting the action handle

@mwilliams
With the rptdesign structure,i have... i am unable to get it as a hyperlink in viewer as well..
So i think i need to set some params in my design structure in my servlet because of which i am unable to render it as a hyperlink.

Please help !!!!!
