[magnamux]

HI,
I'm trying to use JFreeReport in a web application with Tomcat 5.5.9
I'm using the same librairies that the example found on jfree.org

When i try to display a report from my servlet i get the following message:

java.lang.NoSuchMethodError: org.jfree.base.log.DefaultLog.installDefaultLog()V
	org.jfree.report.JFreeReportBoot.getInstance(JFreeReportBoot.java:234)

this exception is launch at the second line of my init method:

public void init() throws ServletException
	  {
	    super.init();
	    JFreeReportBoot.getInstance().start();
	  }

i'm using jfreereport-0.8.6-6 with jfreereport-ext-0.8.6-5 and jcommon-1.1.0

If someone can help me , i'll be pleased

thanks

Hi,

always use the same JFreeReport version and the same JFreeReport-ext version. Everything else will get you in trouble. And more than that - JFreeReport uses a newer version of JCommon now - so you have to use the one from JFreeReport or the latest build from the CVS.

I tried with same version files, i deployed the jfreereport-ext-0.8.6-6.war ,
and it works. but when i use these jar in my application, i still get the same error.

I looked into the jcommon and i found the installDefaultLog(), and it still launch a nosuchmethoderror.

thanks for future helper!

Hi,

the most common cause of this are multiple copies of jcommon in the classpath. Maybe you're having an old copy of jcommon sitting in the $JDK/jre/lib/ext directory or something else?

I search my entire diskd and i don't have any other jcommon in my classpath, in fact i tried with all other jcommon.jar remove from my disc and still the same error.

I have jfreechart totally functionnal in my web application, maybe i can affect my jfreereport.

Any solutions

I use jfreerepot-0.8.7-5 and eclips. To run as -> classpath -> bootstrap includ jcommon-1.0.5.jar. You found this jar in jfreereport-0.8.7-5\lib.
