try to give the same expression ("new Boolean($F{yourData} != null)") also to the property "Print when expression" of the "color" label... it should work and automatically resize the height of the column... maybe... Giovanni ...La puissance est rien sans controle...

hi, i'm not very able with english (and also with reports) so i can't understand very well your first problem but we should consider that the detail band automatically resize itself by contents (the recordset). Otherwise you should wait for another one's reply (more expert then me). For your second problem, instead, you should find in your data textfield properties the property "Print When Expression" and write like expression something like this: "new Boolean($F{yourData} != null)". I hope to help you bye Giovanni ...La puissance est rien sans controle...

understand thanks Giovanni ...La puissance est rien sans controle...

Hi jljunked, first of all sorry for my scholastic english... i'm new with jasper reports but i try to help you: I've tried your code in a project and it works (not in a servlet... and idon't know if is the same thing). The only difference with that you've done is the way to compile. You have used the "JasperCompileManager.compileReportToFile() " method and i've used the "JRXmlLoader.load() method. Have a look at what i've done: String fileJrxml="C:/<windows path>/Results.jrxml"; InputStream is = new InputStream(fileJrxml); //if the path is relative (the jrxml file is in your project) you should use "this.class.getResourceAsStream(fileJrxml)"; JasperReport jr = this.compile(is); //see the attacched code to have a look at this method. JasperPrint jasperPrint= JasperFillManager.fillReport(jr, parameters,<your JRDataSource>) byte[] report = JasperExportManager.exportReportToPdf(jasperPrint); FileOutputStream fos = new FileOutputStream("C:test.pdf"); fos.write(report); fos.flush(); fos.close(); I hope this help you Giovanni ...La puissance est rien sans controle... Code://in this method, to compile, i've used the "JRXmlLoader.load()" method public static JasperReport compile(InputStream is) { JasperReport jasperReport = null; try { JasperDesign jasperDesign = JRXmlLoader.load(is); JRJavacCompiler compiler = new JRJavacCompiler(); jasperReport = compiler.compileReport(jasperDesign); } catch (JRException e) { throw new RuntimeException(e.fillInStackTrace()); } return jasperReport; } Post Edited by giobby at 10/15/2009 09:48

wonderful! this is more clear than my solution... and also allows me to deal the number the variables that i want. For example: new BigDecimal( ( $V{varMain}==null ? 0 : $V{varMain}.doubleValue() ) + ( $V{varSub1}==null ? 0 : $V{varSub}.doubleValue() ) + ( $V{varSub2}==null ? 0 : $V{varSub}.doubleValue() ) + ( $V{varSub...n}==null ? 0 : $V{varSub}.doubleValue() ) ) is true? And also another question: can I do the same thing declaring "new Double(...)" instead "newBigDecimal(...)" at the beginning to avoid to write ".double value()" all the times (assuming that the type of my vars is Double)? ps. I ask this because i can't do any attemps now. All the project are in another place... thanks a lot! Giovanni ...La puissance est rien sans controle...

hi denys i'm not able with english and also not able with reports... but if i've understand what is your problem (and humbly i've to say that i'm not sure...) you should only put your "total" variable in a text field situated in the summary band and not in details one. but if you want to be sure to fix the problem you should waiting for another one's reply (...another one more expert than me) Giovanni ...La puissance est rien sans controle...

Hi everybody, I must doing this operation in a text field: varMain //from main report varSub //from sub report if (varMain != null && varSub !=null) then print varMain.add(varSub) else if (varMain != null && varSub ==null) then print varMain else if (varMain == null && varSub !=null) then print varSub else print null I tried with this solution... $V{varMain} !=null ? new BigDecimal($V{varMain}.toString()).add(($V{varSub} ==null ? new BigDecimal("0") : new BigDecimal($V{varSub}.toString()))) : ($V{varSub} ==null ? null : new BigDecimal($V{varSub}.toString())) ...and it works. Question: Is there a less complicated way to do this kind of operations (especially when the variables to deal are more than 2)? thanks in advance Giovanni ...La puissance est rien sans controle...

Please help me Giovanni ...La puissance est rien sans controle... Post Edited by giobby at 10/12/2009 10:12 Post Edited by giobby at 10/12/2009 10:13

thanks for the help Giovanni ...La puissance est rien sans controle...

please can someone answer at least to the second question (about differences between details/summary bands an their ralation whit subreports)? Giovanni ...La puissance est rien sans controle...

Hi guys, i'm using i report for 1 week... and after reading a lot of discussions in this (and others) forum i can understand that is complicated make not basilar operations (i met several problems just for reading values from a subreport) . Questions: 1-Someone may help me to find examples to learn all about groups, expressions and the correct use of details/summary bands (and their differrences in relation with subreports)? 2- Only to confirm a matter: when i put a sub report in detail band the result is: ------------------------------------------------------detail band--------------------------------------------------- 1st record->main rpt 1st record-> sub rpt 2nd record->sub rpt ... 2nd record->main rpt 1st record-> sub rpt 2nd record->sub rpt ... 3rd record->main rpt ... ------------------------------------------------------end detail band--------------------------------------------------- is true? And when i want to append the result of a sub report (whitout making an union of queries) i must put the sub in the summary band to obtain: ------------------------------------------------------detail band--------------------------------------------------- 1st record->main rpt 2nd record->main rpt ------------------------------------------------------end detail band--------------------------------------------------- ------------------------------------------------------summary band--------------------------------------------------- 1st record-> sub rpt 2nd record->sub rpt ... ------------------------------------------------------end summary band--------------------------------------------------- isn't true? THANKS Giovanni ...La puissance est rien sans controle...

Hi, i'm new, but in my case the best way was to dispose all the reports NESTED in the summary band and before the report icon i put an interrupt (break) line also in the summary

Hi everybody, i'm a junior developer and I use Ireport since 1 week... after a full immersion, now I can create report of medium difficulty... but now I meet the problem of return values from a subreport to report main...
