WARNING: Found two components for namespace

[cn73]

Good morning.

I've opened, edited and saved, with iReport 3.6.0, a report, originally created with iReport 3.0.0. When I compile my report I get this strange WARNING:

11-nov-2009 9.27.03 net.sf.jasperreports.engine.component.ComponentsEnvironment findComponentBundles
WARNING: Found two components for namespace http://jasperreports.sourceforge.net/jasperreports/components

what this means?

anybody?

This means that JasperReports is present twice on the report classpath.  I don't know how iReport manages classloaders, so I can't tell how could that happen.  Do you have a classpath configured in iReport?

Regards,

Lucian

the "problem" occurs when compiling the report in my project, through jasperreports-maven-plugin ... so in the pom I must use a double dependence, one for Plugin, the other for the project. Now it is clear the cause, thanks;)

Code:

<plugin>                <groupId>org.codehaus.mojo</groupId>                <artifactId>jasperreports-maven-plugin</artifactId>                <configuration>                    <sourceDirectory>                        src/main/jasperreports                    </sourceDirectory>                    <outputDirectory>                        src/main/resources/jasperbin                    </outputDirectory>                    <javaDirectory>                        target/jasperreports/java                    </javaDirectory>                    <!-- <keepJava>true</keepJava> -->                </configuration>                <executions>                    <execution>                        <phase>generate-resources</phase>                        <goals>                            <goal>compile-reports</goal>                        </goals>                    </execution>                </executions>                <dependencies>                    <dependency>                        <groupId>jasperreports</groupId>                        <artifactId>jasperreports</artifactId>                        <version>3.5.3</version>                        <scope>provided</scope>                                            </dependency>                                    </dependencies>            </plugin>

Make sure both the plugin and the project dependencies match.  That solved my issue that caused this message. 

Using: 6.9.0 jasper;  1.0-beta-2 plugin
