Customizer class not found error

[ashwini]

Hi This is Amit.

I am using iReport and Jasper.

I have created a customizer class and it compiles fine.

But while running the report it gives error as

 

 

Error filling print... Could not create chart customizer instance. net.sf.jasperreports.engine.JRRuntimeException: Could not create chart customizer instance.      at net.sf.jasperreports.engine.fill.JRFillChart.<init>(JRFillChart.java:326)      at net.sf.jasperreports.engine.fill.JRFillObjectFactory.getChart(JRFillObjectFactory.java:582)      at net.sf.jasperreports.engine.base.JRBaseChart.getCopy(JRBaseChart.java:552)      at net.sf.jasperreports.engine.fill.JRFillElementGroup.<init>(JRFillElementGroup.java:88)      at net.sf.jasperreports.engine.fill.JRFillElementContainer.<init>(JRFillElementContainer.java:90)      at net.sf.jasperreports.engine.fill.JRFillBand.<init>(JRFillBand.java:83)      at net.sf.jasperreports.engine.fill.JRFillObjectFactory.getBand(JRFillObjectFactory.java:385)      at net.sf.jasperreports.engine.fill.JRBaseFiller.<init>(JRBaseFiller.java:432)      at net.sf.jasperreports.engine.fill.JRVerticalFiller.<init>(JRVerticalFiller.java:77)      at net.sf.jasperreports.engine.fill.JRVerticalFiller.<init>(JRVerticalFiller.java:59)      at net.sf.jasperreports.engine.fill.JRFiller.createFiller(JRFiller.java:147)      at net.sf.jasperreports.engine.fill.JRFiller.fillReport(JRFiller.java:57)      at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:402)      at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:234)      at it.businesslogic.ireport.IReportCompiler.run(IReportCompiler.java:934)      at java.lang.Thread.run(Unknown Source)  Caused by: java.lang.ClassNotFoundException: test      at java.net.URLClassLoader$1.run(Unknown Source)      at java.security.AccessController.doPrivileged(Native Method)      at java.net.URLClassLoader.findClass(Unknown Source)      at java.lang.ClassLoader.loadClass(Unknown Source)      at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)      at java.lang.ClassLoader.loadClass(Unknown Source)      at java.lang.ClassLoader.loadClassInternal(Unknown Source)      at java.lang.Class.forName0(Native Method)      at java.lang.Class.forName(Unknown Source)      at net.sf.jasperreports.engine.util.JRClassLoader.loadClassForRealName(JRClassLoader.java:132)      at net.sf.jasperreports.engine.util.JRClassLoader.loadClassForName(JRClassLoader.java:72)      at net.sf.jasperreports.engine.fill.JRFillChart.<init>(JRFillChart.java:323)      ... 15 more

Hi Amit,

Just mention the customizer class in the chart properties. Prepare a jar file with the customizer class and add the jar file to the classpath of iReport.

Hi Shrikanth,

Thanks for the reply.

 

Can u tell me the detail procesure to do this.

Do i need to make jar of .class file and put it in classpath?

Also should i mention the custmoizer class name like test.jar in the chart properties

 

Please help.

 

Thanks.

Amit

[dnvsrikanth]

I have created test.jar file of the customizer class. i have placed it in clsspath of ireport and specified the customizer class proerty to 'test'.

Plaese suggest somthing.

Hi Amit,

 

Without adding Customizer class in tools properties, how did u get the error message you have mentioned at the start?

 

I am getting the same error message while generating the report. Please update the thread if you get any solution for the said error message.

 

thanks,

Sreejith

I have added the customizer class in tools properties but it is not peaking up.

Hi

 

Check whether the jar file is included in classpath or not or check whether you have given any package for the costomiser class.

 

Thanks,

Is the class really called test?

java.lang.ClassNotFoundException: test 

Put the class in a package and put all in a jar.
