Hi all, I'm scratching my head for days to find out how I could evaluate expressions using jasperreports API? Say, I have the following imageExpression: <imageExpression class="java.lang.String"><![CDATA[$P{IMG_DIR} + $P{COMPANY_LOGO}]]></imageExpression> Is there an easy way using jasperreports API to find out to what file this expression points to? BR, Cyrille

Hi, Can someone explain me how I can "evaluate" a subreport's expression? I mean, I'm getting a subreport's expression using the getExpression() method: JRExpression expression = subreport.getExpression(); If I cast this expression into a String, I can find back my subreportexpression parameter's value ('$P{SUBREPORT_DIR} +"subreport_1.jasper"'): String s = expression.toString(); Now, what I would like is to find the actual filename this expression refers to. That's, translating '$P{SUBREPORT_DIR} +"subreport_1.jasper"' into "/usr/lib/reports/subreports/subreport_1.jasper"). Hopefully, without going through the JRExpression->String cast. Is there a nice way to do that? Or am I stuck with the solution explained at http://stackoverflow.com/questions/10004800/jasper-reports-how-to-compile-subreports ? Best regards, Cyrille
