net.sf.jasperreports.engine.JRException：找不到字节数据 [英] net.sf.jasperreports.engine.JRException: Byte data not found

问题描述

我正在尝试传递给jasper报告字符串位置的模板。所以我在模板和值中传递参数的键。当我在项目中有图像时，一切都在工作，但我希望在另一个地方有它。有没有办法从中读取参数，例如属性文件？我不知道为什么这个解决方案不起作用：

I'm trying to pass to template of a jasper reports string location. So I'm passing key of a parameter inside template and value. Everything was working when I had image inside my project, but I would like to have it on the other place. Is there any way to read parameters from, for instance properties file? I don't know why this sollution is not working:

我的形象：

<parameter name="imagesDir" class="java.lang.String" isForPrompting="false"/>

...

<image isLazy="true">
    <reportElement key="image-1" style="PHLabel" x="0" y="0" width="160" height="33"/>
    <imageExpression class="java.lang.String"><![CDATA["$P{imagesDir}"+"logo.bmp"]]></imageExpression>
</image>

错误：

Error during exporting report statement_account_10 to PDF.
net.sf.jasperreports.engine.JRException: Byte data not found at : 
((java.lang.String)parameter_imagesDir.getValue())logo.bmp

推荐答案

好的我发现它...
应该是：

Ok i found it... Should be:

<image isLazy="true">
    <reportElement key="image-1" style="PHLabel" x="0" y="0" width="160" height="33"/>
    <imageExpression class="java.lang.String"><![CDATA[$P{imagesDir}+"logo.bmp"]]></imageExpression>
</image>
