Jasper reports 使用jasper report时出现FileNotFoundException

我试图在Liferay portlet中创建Jasper报告，但出现以下错误：

请帮助我。

我认为您的.jasper文件不在应用程序的上下文路径中（至少应用程序找不到它）

是否确定/report文件夹位于生成路径中？？ 如果不是，则将其添加到生成路径

否则，请尝试使用类似于以下内容的方法：JasperReport report=jaspecompilemanager.compileReport（“classpath:src/com/ztscorp/lms/reports/HibernateQueryDemoReport.jasper”）

试试这个

改变

JasperReport report = JasperCompileManager.compileReport("src/com/ztscorp/lms/reports/HibernateQueryDemoReport.jrxml");

到

希望有帮助

在我的例子中，我有一个图像url参数，必须显式地将属性isForPropmting设置为false，如下所示：

<parameter name="LOGO_URL" class="java.lang.String" isForPrompting="false">
        <defaultValueExpression><![CDATA[]]></defaultValueExpression>
    </parameter>

为帮助未来用户：

我看到了这些问题

OP正在尝试编译

.jasper

，这些

.jasper

文件已通过命令

jaspecompilemanager编译。应使用compileReport

将

.jrxml

编译为

.jasper

。有关jasper报告文件类型的更多信息，请参阅

如果您的包/发行版（src）中有

.jasper

，加载报表的正确方法是使用类加载器（因此src将更改为bin）

如果它在发行版的之外，您可以简单地使用带有相对或绝对路径的

文件

JasperReport report = (JasperReport) JRLoader.loadObject(new File("jasperFolder/HibernateQueryDemoReport.jasper");

---

好的，伙计们，这对我很有用

  ***con=DBConnection.getConnection();
  JasperPrint  jp = JasperManager.fillReport(<reportname>.jasper",null,con);
        JasperViewer.viewReport(jp, false);***

***con=DBConnection.getConnection（）；
JasperPrint jp=jaspermager.fillReport（.jasper），null，con；
JasperViewer.viewReport（jp，false）***

---

在此之后，复制或剪切jasperfile，例如（your_reportname.jasper和your_reportname.jrxml），并转到项目的文件目录（在netbeans中很容易找到）并将它们粘贴到项目的build.xml文件夹中。确保已导入Necesary类JAR并运行..我在我的netbeans ide中使用用于netbeans的jasperreport 3.7.4插件

我必须在build.xml文件中编写什么，因为在build.xml文件中，我编写了编译src.dir.Eclipse 3.4和jboss的代码，作为服务器现在我是我正在编写JasperReport report=jaspecompilemanager.compileReport（“src/com/ztscorp/lms/reports/HibernateQueryDemoReport.jrxml”）；但仍然收到相同的错误我按照你的建议进行了更改，但出现了相同的问题，因此我认为存在任何编译错误，我的意思是文件夹可能正在正确编译。给我15分钟，我将在netbeans中尝试我的代码，并会回复。另外，如果你能发送代码，那将是最好的…！！！你可以阅读javadoc：

JasperReport report = (JasperReport) JRLoader.loadObject(new File("jasperFolder/HibernateQueryDemoReport.jasper");

  ***con=DBConnection.getConnection();
  JasperPrint  jp = JasperManager.fillReport(<reportname>.jasper",null,con);
        JasperViewer.viewReport(jp, false);***
