2001 JI Open Discussion Posted August 30, 2006 Share Posted August 30, 2006 By: srinivas reddy - srinivasreddy13 sub-report problem HELP!!!! 2003-02-24 05:08I have created a main report which shows simple data frm the DB. It has one ID and Name field from products table. And then I have created a subreport file(subreport1) which should show description of these products. here my query was "select description from prod_desc where pid = ${ID}". and i have also created a parameter Field name=ID, Class type=java.lang.Integer, Is for prompting=true. Now How should i compile it? When i complie it with specifing connection it gives error as it couldnt recognise what is $P{ID}. And when i compile it without connection it runs perfectly and displays the report (.pdf) with data as Null. And, Next i create a mainreport file (mainreport) where I have the query as "select id as pid, name from products". I place these fields in detail section and also created a parameter by the name subreport1, dori.jasper.engine.JasperReport, true(this i saw in jasperreports demo files). Then I palced the subreport in detail band and set the following properties: Common tab-> checked remove line when blank and print repeated values subreport1->connection/datasource expression: use connection expression -- $P{REPORT_CONNECTION} subreport2->subreport expression: dori.jasper.engine.JasperReport subreport parameters : name=ID and Expression: $F{pid}. Now when i compiles the mainreport file it gets compiled with connection and displayes only the records of my mainreport without displaying any records in my subreport.... i am not sure whether its running fine or not. I am also not sure whether i followed right steps.... please guide me asap... its urgent.... i want complete steps for creating a simple subreports.... regds, Sri By: Mohan Joshi - mohanjoshi1 RE: sub-report problem HELP!!!! 2003-02-28 02:42Hi, I am also having same problem, Can any experts have tried to run the Jasperreports subreport example & found success ? Regards Mohan By: tone zalokar - tonez0 RE: sub-report problem HELP!!!! 2003-02-28 05:30Compile reports and subreports without connection. Then use iCompiler without filling query statement in icompiler window! If it exists delete it from iCompiler window! tz By: kags - wakabiro RE: sub-report problem HELP!!!! 2004-04-13 16:51I had a problem like the first one you listed and I use $P{ID} instead of ${ID} and it worked. Hope this helps. Kags By: just - justjasper RE: sub-report problem HELP!!!! 2004-04-13 23:11I had the same problem,u can solve it by replace ${ID} with $P{ID}.good luck.
