By: Dejan - dejanic Problem with 1.2.3 and Hibernate 2006-06-12 05:55 Hello. I have a problem with 1.2.3 version of iReport. In version 1.2.2 report works fine but same report won't work under 1.2.3 version of iReport. I'm using HQL for report query. This is error: Hibernate session closed java.lang.NoSuchMethodError: java.math.BigDecimal.<init>(I)V at net.sf.jasperreports.engine.fill.JRBigDecimalIncrementerFactory.<clinit>(JRBigDecimalIncrementerFactory.java:46) at net.sf.jasperreports.engine.fill.JRDefaultIncrementerFactory.getFactory(JRDefaultIncrementerFactory.java:108) at net.sf.jasperreports.engine.fill.JRFillVariable.getIncrementer(JRFillVariable.java:287) at net.sf.jasperreports.engine.fill.JRCalculator.calculateVariables(JRCalculator.java:134) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillDetail(JRVerticalFiller.java:621) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillReportStart(JRVerticalFiller.java:228) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillReport(JRVerticalFiller.java:128) at net.sf.jasperreports.engine.fill.JRBaseFiller.fill(JRBaseFiller.java:750) at net.sf.jasperreports.engine.fill.JRFiller.fillReport(JRFiller.java:123) at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:420) at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:256) at it.businesslogic.ireport.IReportCompiler.run(IReportCompiler.java:728) at java.lang.Thread.run(Thread.java:534) Print not filled.

By: Neil Lamka - neil_lamka Not sure this is an iReports question, but? 2006-06-13 21:11 I have a report that I have had to totally redo in an attempt to move to JR 1.2.x from JR 0.55. I've posted several questions about it but have had no responses so decided to try and redo this report using a scriptlet. Now, I'm not sure that this has anything do to with either iReport or JasperReport but I'm looking for some input how what might be wrong with the following. What I have is a "getter" method that is called and is to return a concatenated string of values back to the main report. The code is the following public String getReliefString() { String [] strs = (String[]) overtimeAssignments.toArray( new String[0]); StringBuilder r = new StringBuilder(); String rc = null; java.util.Arrays.sort(strs, String.CASE_INSENSITIVE_ORDER); int i; for (i=0; i < strs.length; i++) { System.out.println(strs); if (i==0) r.append(strs); else r.append(", "+strs); } return r.toString(); } where the overtimeassignments variable is a java.lang.ArrayList that is created and populated based on the returned row values. This method is called in the summary band of the report. My problem is that I can not figure out for the life of me what would cause the JVM to go to 100% cpu utilization and never quit when I call this method. If I comment out the lines if (i==0) r.append(strs); else r.append(", "+strs); and then dummy up the return to return something like return strs[0]; everything works properly and the list of items I expect are listed from the System.out.println(strs); statement so I know that the array is properly constructed. So, since I'm not a java expert, can anyone tell me what is wrong with the above 4 lines of code that would cause the JVM to crash? I have tried changing the code to just use a String as in if (null == rc) rc = new String(strs); else rc = new String( rc + ","+strs); with no luck. I'm running on Win/XP with the Sun 1.5.0_06 JVM in case that gives anyone a clue. Thanks Neil

By: Rick62 - rick62 the way to change FORECOLOR ? 2006-06-08 01:48 Hi all, is there somebody who knows how to change FORECOLOR of displayed DATA ? Which is the correct coding ? Something like : $F{quantity}.doubleValue() < 100 ? setForecolor(255,0,0):setForecolor(0,0,0) The purpose is to color data in red in one case and in black in other case, dynamically. (I've already used the method with 2 textfield overlapped and the printWhenExpression but it is not the best solution). Someone can help me ? Thanks for your answers. By: Bat(ch)man - dekit RE: the way to change FORECOLOR ? 2006-06-08 03:07 The printWhenExpression is the way to go. Should work out, even for you By: Rick62 - rick62 RE: the way to change FORECOLOR ? 2006-06-08 05:42 This is a solution which works, I know, I've used it. But not easy to modify if you have a lot of textfields. I think that my proposal : $F(myValue) < 0 ? setForecolor(red):setForecolor(black) would be more simple. So, which is the correct coding in this case ? By: Armandor - armandor777 RE: the way to change FORECOLOR ? 2006-06-08 11:26 I have a similar problem, but I´m using the numbers of a string data. By: Rick62 - rick62 RE: the way to change FORECOLOR ? 2006-06-13 08:09 I've got THE solution. Write the conditional sentence in this way, for exemple : ($F{quantity} < 100)? ("<style forecolor="red">" + $F{quantity}.toString()+ "</style>"): ($F{quantity}.toString()) ... and it works.

By: ailatan - ailatan object present in the report 2006-06-13 06:55 exists some form to make reference within iReport to objecto present (that is to say, the instance of the class java on which the data appear)? Try with “thisâ€, but it makes reference to the report and not to object present By: TBG - thebiggunner RE: object present in the report 2006-06-13 06:57 Can you give us an exact example?:) By: ailatan - ailatan RE: object present in the report 2006-06-13 07:09 First of all, thanks to try to help me! To see if I can be explained better… I have a class XXX of which they extend 3 subclasses. The masterful report sends as parameter to a subreport a set of “itemsâ€; each one of these items is instances of class XXX. Depending on the value of an attribute of this class XXX, I must cast the instance received to some of its dependent subclasses to be able to make reference to other data. Again… thanks! By: TBG - thebiggunner RE: object present in the report 2006-06-13 07:39 Hmm...maybe you should make static class properties to reach them. By: TBG - thebiggunner RE: object present in the report 2006-06-13 07:47 Here you are a simple example.. public class Test { private static String testData="test"; public static String getTestData() { return this.testData; } } After that you can use this class... Test.getTestData();

By: MAF82 - laportegerard iReport subreport connection expression 2006-06-02 08:23 When working in sql mode in a report, how can I give a different connection expression to a subreport to access a different database ? I cannot use the buit-in parameter "REPORT_CONNECTION" . Thanks for help . By: Javy Dreamer - javydreamercsw RE: iReport subreport connection expression 2006-06-02 08:40 What version are you using? In 1.2.2 the subreport wizard provides for this set-up. By: MAF82 - laportegerard RE: iReport subreport connection expression 2006-06-12 02:36 I was using version 1.1.0, so I downloaded version 1.2.3 and I think I can solve my problem if I remove and create again my sub-report. Thanks for your help. By: MAF82 - laportegerard RE: iReport subreport connection expression 2006-06-12 07:27 Sorry but it doesn't work ! With version 1.2.3 I can give a different connection for the sub-report, but at execution time I have the message "ORA_00942 Table ou vue inexistante". My sub-report works well alone. In the sub-report parameters in the main report, the connection expression remains at value $P{REPORT_CONNECTION}. By: agh - alvarogh RE: iReport subreport connection expression 2006-06-12 12:00 Maybe you must use $P!{REPORT_CONNECTION}. The ! indicates use the contents of your parameter.

By: stefan - grossmanns Classnames in buckets for a crosstab. 2006-06-12 07:08 I get the following error, if I try to enter another than the proposed classes in a crosstab group: "Please enter a valid class name for the bucket!" I need this to wrap a special sort order and a text for the column and row headers. If I modify the bucket class with a text editor, everything works fine. Is this a bug in iReport? See also the thread “crosstab column heading order“ of the jasper reports help forum.

By: Javy Dreamer - javydreamercsw Conditional Parameter value 2006-06-09 07:02 Maybe I'm doing a basic mistake but here it goes. I have a parameter passed to a subreport that I need it to be set baset on a field in the report. It seems that there's something missing in the expression or that I'm doing it all wrong: ( $F{REASON}=="BATCH WAS INITIATED" ? "" : ( $F{REASON}=="MFG VERIFICATION" ? "BATCH WAS INITIATED" : ( $F{REASON}=="QUALITY VERIFICATION" ? "MFG VERIFICATION" : ( $F{REASON}=="BATCH CLOSED" ? "QUALITY VERIFICATION" : "N/A" ) ) ) ) After that modification the subreport is always empty. Any ideas? By: Rob Karatzas - tutor RE: Conditional Parameter value 2006-06-09 07:16 not sure if I'm following you... 1. if you pull up JUST the subreport, look at the parameter properties, put in a default value, is the subreport empty or not? 2. the expressions you are showing look 'odd'. I would expect there to be something more 'lookup friendly' AND/OR I would expect this kind of logic to be 'baked' into your SQL statement as 'CASE' logic (versus this being evaluated at runtime). rob By: Javy Dreamer - javydreamercsw RE: Conditional Parameter value 2006-06-12 06:22 Moved the conditions to an aditional field (case) to the SQL and worked wonders. Anyways there should be a way to pull that of from iReport. Thanks

By: Gareth Davies - telcontar4 Compiler Performance 2006-06-06 12:20 I recently upgraded from 1.1.1 to 1.2.x and have noticed a significant performance dropoff with report compilation. The problem was pretty much the same with all 1.2.x versions, both using the Windows installer (I'm running XP Pro) and extracting from the ZIP archive. For a report with 3 fields and 2 rows, it takes almost 60 seconds for iReport to compile it! Using Task Manager, I can see that the java process never uses more than about 68MB of RAM. Has anyone else observed this (and resolved the issue?) By: Gareth Davies - telcontar4 RE: Compiler Performance - 1.1.0 and 1.2.2 2006-06-06 13:19 It now appears that iReport 1.1.0 suffers from the same abysmal performance as 1.2.0, 1.2.1 and 1.2.3. However, 1.2.2 (when installed via ZIP extraction) performs just fine - it's problem is that it doesn't load the Classpath entries correctly on startup, so I have to re-enter them every session...

By: Gareth Davies - telcontar4 RE: Compiler Performance - More Info 2006-06-06 14:22 It appears that this is a Classpath issue. In order to use JRDataSourceProviders to preview reports filled with our domain objects, we have to add our application's classpath root directory (i.e. OurApp/classes) to the iReport Classpath. If I remove this directory from the classpath (either by using 1.2.2 or by manually removing it before exiting 1.2.3 etc.), the next time I run iReport the compilation process is about 50 times faster. I can then add our app's classpath directory back and everything is still OK. However, if I don't remove the directory before quitting iReport - or if I add it back to the classpath immediately after restarting iReport and *before* compiling without it - the hideous performance returns. I have also tried adding our application's JAR file instead of the classes directory with the same result. Anyone have any ideas?
