We are migrating some of our reports from a custom servlet integration to the tag library style. The only problem we are having is with the drill throughs.<br />
<br />
The url that is being generated looks something like:<br />
/viewReport?__design=path/to/ReportDesign.rptdesign&somethings=Here&more=yes<br />
We need it to look like<br />
/path/to/ReportDesign.rptdesign.do?somethings=Here&more=yes<br />
In our old implementation, we extended HtmlActionHander and set it like:<br />
HTMLEmitterConfig htmlConfig = new HTMLEmitterConfig();<br />
htmlConfig.setActionHandler(new MyHTMLActionHandler());<br />
htmlConfig.setImageHandler(new HTMLServerImageHandler());<br />
engineConfig.getEmitterConfigs().put("html", htmlConfig);<br />
<br />
How can we override the HTMLActionHandler for the tag library in the same way? Preferably we would like to use the same class as we are not having any issues with it.<br />
