2001 JI Open Discussion Posted August 17, 2006 Share Posted August 17, 2006 By: Carole Song - miyu76 Need help displaying object information 2002-10-28 12:07I am working with java servlets and was wondering if there was a way to pass in specific objects outside of my main query results and call their methods. would it be possible to set my object as a parameter? I have tried to perform this action but have the following result in my report: (((inetcourier.MyObject)parameter_TheObject.getValue())).getMethod() when declaring this: <parameter name="TheObject" class="inetcourier.MyObject"/> <textFieldExpression class="java.lang.String">"($P{TheObject}).getName()"</textFieldExpression> Am I attempting to do something that is unsupported or illegal? If someone could tell point me in the right direction, that would be great! Thanks, Carole By: Teodor Danciu - teodord RE: Need help displaying object information 2002-10-28 13:04 Hi, The correct expression is: <textFieldExpression class="java.lang.String">$P{TheObject}.getName()</textFieldExpression> Remove the extra quotes. Good luck! Teodor By: Carole Song - miyu76 RE: Need help displaying object information 2002-10-29 07:10Thanks for the syntax correction =) I actually have another problem and I don't see where I can go to fix it. inetcourier.MyObject extends a class called the PersistentObject, which is from a jar called the persistence layer. When I attempt to compile my work, i now get this error: dori.jasper.engine.JRException: Errors were encountered when compiling report design: D:Projectsinetcouriertempshowmanifest.java:0: Class pl.PersistentObject not found in class inetcourier.MyObject. /* ^ 1 error at dori.jasper.engine.design.JRCompiler.compileReport(JRCompiler.java:145) I am assuming that this error is occuring because jasper is unable to find the pl.jar. How do I set up Jasper so that it will be able to reference this library? Thanks for your help!

I hope this helps. Teodor By: Carole Song - miyu76 RE: Need help displaying object information 2002-10-29 13:37that worked great! I just appended the jars I needed to what was already there on the classpath. Thanks a bunch for your help! Carole Link to comment Share on other sites More sharing options...
