如何修正“输入流在: net/sf/jasperreports/fonts/fonts.xml”错误？

Question

我使用netbeans7.4创建了一个java桌面应用程序。我将ireport 5.6.0用于报告目的。我通过字体扩展创建了自定义字体。当我(从文件夹)内部/外部运行应用程序时，所有这些都非常有效。

现在，当我将所有内容编译成一个jar (运行Target>Other目标>包换存储)时，我得到了运行该文件的以下错误。(我需要编译到一个jar，因为我想创建一个安装程序)

除了Ireport 之外，每件事情都很好(数据库、应用程序)。有人能帮我解决这个问题吗。预先感谢你们对我的支持。

有人能告诉我下面的代码是否完美吗？我使用这段代码生成一个jar文件。

<target name="package-for-store" depends="jar">
    <property name="store.jar.name" value="myProject"/>
    <property name="store.dir" value="store"/>
    <property name="store.jar" value="${store.dir}/${store.jar.name}.jar"/>
    <echo message="Packaging ${application.title} into a single JAR at ${store.jar}"/>
    <delete dir="${store.dir}"/>
    <mkdir dir="${store.dir}"/>
    <jar destfile="${store.dir}/temp_final.jar" filesetmanifest="skip">
        <zipgroupfileset dir="dist" includes="*.jar"/>
        <zipgroupfileset dir="dist/lib" includes="*.jar"/>
        <manifest>
            <attribute name="Main-Class" value="${main.class}"/>
        </manifest>
    </jar>
    <zip destfile="${store.jar}">
        <zipfileset src="${store.dir}/temp_final.jar"
        excludes="META-INF/*.SF, META-INF/*.DSA, META-INF/*.RSA"/>
    </zip>
    <delete file="${store.dir}/temp_final.jar"/>
</target>

这可能是老茉莉报告造成的，

使用jasperreports.5.0.0.jar或更高版本，其中包括缺少的fonts.xml。
