I use "frame" element for grouping Label_2 : Value2 - I set the positionType of Frame to Float , but they are not displayed. Can anyone help me? Thanks

Hi, I attach the log file: I don't understand what libs I must to add. If I add all libs from jasper libs then in my web app under linux there are a bug described in attached file. If I don't add some libraries the then there are : Error retrive from bean... :blink: Big thanks [file name=login-518e2855ccf083cee982d4c9ce79f1e2.html size=8132]

Can somebody tell me is there are some campatibility issue with jasper libs and other libs?After adding jasper libs my web app have been broken:(

Hi All, I add jasper libs to my web App on Windows - everything works OK. But when I do the same steps on Linux there are some errors. What can be the reason of this strange behaviour and how to fix that?

Hi All, I add to my web - app next libraries: Code: commons-collections-2.1.jar, commons-digester-1.7.jar, jasperreports-2.0.4.jar, jasperreports-2.0.4-applet.jar, jasperreports-2.0.4-javaflow.jar, jcommon-1.0.0.jar, jfreechart-1.0.0.jar, xalan.jar, xercesImpl.jar, xml-apis.jar. Compilation is OK. But when I run my project the next exception displays: Code:[code] net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file: /opt/netbeans-5.5/enterprise3/apache-tomcat-5.5.17/bin/PieChartDemoReport_1211714423569_535946.java:4: package net.sf.jasperreports.engine does not exist import net.sf.jasperreports.engine.*; ^ /opt/netbeans-5.5/enterprise3/apache-tomcat-5.5.17/bin/PieChartDemoReport_1211714423569_535946.java:5: package net.sf.jasperreports.engine.fill does not exist import net.sf.jasperreports.engine.fill.*; ^ /opt/netbeans-5.5/enterprise3/apache-tomcat-5.5.17/bin/PieChartDemoReport_1211714423569_535946.java:18: cannot find symbol symbol: class JREvaluator public class PieChartDemoReport_1211714423569_535946 extends JREvaluator ^ /opt/netbeans-5.5/enterprise3/apache-tomcat-5.5.17/bin/PieChartDemoReport_1211714423569_535946.java:25: cannot find symbol symbol : class JRFillParameter location: class PieChartDemoReport_1211714423569_535946 private JRFillParameter parameter_REPORT_RESOURCE_BUNDLE = null; ^ /opt/netbeans-5.5/enterprise3/apache-tomcat-5.5.17/bin/PieChartDemoReport_1211714423569_535946.java:26: cannot find symbol symbol : class JRFillParameter location: class PieChartDemoReport_1211714423569_535946 private JRFillParameter parameter_REPORT_CLASS_LOADER = null; How to fix this problem?May be I must to add some additional library? Big Thanks!

Hi, thanks for response. I have a JR version 2.0.4 In Windows netbens version 5.0 everything works OK but on Linux(Debian) after adding libs my web app fails. I make reports with one JR 2.0.4(in my app I use libs of JR for creation and displaying) When I said about compatibility I mean compatibility with maybe jstl :blink: or other netbeans tomcat libs??? Is there some solution?May be in netbeans there are some specific way how to add libs to classpath :blink: or may be some lib from JR I need't to add??? Thanks!

Hi All, after adding Jasper's lib my WebApp doesn't want compile. I attach the log file : Is there some compatibility issue may be? I use : netbeans,Tomcat, mysqlconnector,jstl libs. Thanks. [file name=login.html size=8132] Post edited by: developer, at: 2008/05/16 10:08

Hi, a have the next report Code: <jasperReport name="PieChartDemoReport"> <field name="tailNum" class="java.lang.String" /> <field name="aircraftSerial" class="java.lang.Integer"/> <variable name="totalAircraft" class="java.lang.Integer" calculation="Count" resetType="Group" resetGroup="modelGroup"> <variableExpression> <![CDATA[$F{aircraftSerial}]]> </variableExpression> <initialValueExpression> <![CDATA[new java.lang.Integer(0)]]> </initialValueExpression> </variable> <group name="modelGroup"> <groupExpression> <![CDATA[$F{tailNum}]]> </groupExpression> </group> <summary> <band height="750"> <pieChart> <chart evaluationTime="Report"> <reportElement x="135" y="0" width="270" height="350" /> </chart> <pieDataset> <dataset incrementType="None" /> <keyExpression> <![CDATA[$F{tailNum}]]> </keyExpression> <valueExpression> <![CDATA[$V{totalAircraft}]]> </valueExpression> </pieDataset> <piePlot> <plot/> </piePlot> </pieChart> </band> </summary> </jasperReport> But in my browser insted one chart there several.When I fill a report the data is: tailNum="A" aircarftSerial=10 tailNum="A" aircarftSerial=1 tailNum="B" aircarftSerial=2 tailNum="A" aircarftSerial=20 But in chart it displays on 2 equals part.It seems that aircarftSerial doesn't calculated?? P.S. How to set aggregation functions on iReport? Thanks

Hi , big THANKS I undertand my bug It's working :). Now Image successfuly displays in my browser but instead one image there are several charts and there no aggregation functions on chart.:blink: However Thanks!!! Post edited by: developer, at: 2008/05/10 07:19

Ishannon , Thank You very much for response. I set classpath successfuly(set path to jar file instead C:).But iReport generate me the same report that I did manualy (I began to use iReport because i thought that in my manualy report was a bug).I have a simple Bean which contains String and int field.I want to grup by String field. Code: <jasperReport name="PieChartDemoReport"> <field name="tailNum" class="java.lang.String" /> <field name="aircraftSerial" class="java.lang.Integer"/> <variable name="totalAircraft" class="java.lang.Integer" calculation="Count" resetType="Group" resetGroup="modelGroup"> <variableExpression> <![CDATA[$F{aircraftSerial}]]> </variableExpression> <initialValueExpression> <![CDATA[new java.lang.Integer(0)]]> </initialValueExpression> </variable> <group name="modelGroup"> <groupExpression> <![CDATA[$F{tailNum}]]> </groupExpression> </group> <summary> <band height="750"> <pieChart> <chart evaluationTime="Report"> <reportElement x="135" y="0" width="270" height="350" /> </chart> <pieDataset> <dataset incrementType="None" /> <keyExpression> <![CDATA[$F{tailNum}]]> </keyExpression> <valueExpression> <![CDATA[$V{totalAircraft}]]> </valueExpression> </pieDataset> <piePlot> <plot/> </piePlot> </pieChart> </band> </summary> </jasperReport>As I understand the group field set in KeyExpression- right? But when I try to generate report from Servlet no data displayed but only missing images in my browser :( So I can't undestand is it's bug in my report?and how to set aggregation functions in iReport for charts - is it possible P.S. In my console app the same report show me the : Code:[code] net.sf.jasperreports.engine.JRException: Error retrieving field value from bean : aircraft at net.sf.jasperreports.engine.data.JRAbstractBeanDataSource.getBeanProperty(JRAbstractBeanDataSource.java:127) at net.sf.jasperreports.engine.data.JRAbstractBeanDataSource.getFieldValue(JRAbstractBeanDataSource.java:100) at net.sf.jasperreports.engine.data.JRBeanArrayDataSource.getFieldValue(JRBeanArrayDataSource.java:90) at net.sf.jasperreports.engine.fill.JRFillDataset.setOldValues(JRFillDataset.java:814) at net.sf.jasperreports.engine.fill.JRFillDataset.next(JRFillDataset.java:778) Thank You very much for reading this long text and sorry for my English it's not my native language.

Hi, Ishannon I am new in iReport and JasperReports. When I go to Data -> Report Query -> JavaBean DataSource the dialog shows me Class not fount exception.Check class path. In Options->CLASSPATH i set value for example C: but exception appear again. Could You help me?
