JRException Resource not found at when there is a subreport in Jasper Report
提问by Dilini Peiris
I made a jasper report that includes a subreport using JasperSoft Studio. When i preview it in the studio, it works fine. But when i add it into my java fx project, i have to send the subreport as a parameter to the main report right?
我使用 JasperSoft Studio 制作了一个包含子报告的 jasper 报告。当我在工作室预览它时，它工作正常。但是当我将它添加到我的 java fx 项目中时，我必须将子报表作为参数发送到主报表，对吗？
When i do that i keep on getting an error saying that the subreport resource not found. I dont think there is any spelling errors because i hv tried this with almost all the reports that includes subreports.. still keep on getting that error..
当我这样做时，我不断收到错误消息，指出未找到子报表资源。我不认为有任何拼写错误，因为我对几乎所有包含子报告的报告都进行了尝试。
These are the things i tried 1. compiled the report again using the jaspersoft studio and includeded them again in the project.. 2. included the jrxml file into the project and compiled it with the Compile Manager.. 3. i read some tutorials and questions saying that to put the expression to the subreport element in the main report as
这些是我尝试过的事情 1. 使用 jaspersoft studio 再次编译报告并将它们再次包含在项目中.. 2. 将 jrxml 文件包含到项目中并使用编译管理器编译它.. 3. 我阅读了一些教程和问题说将表达式放在主报告中的子报告元素中
$P{SUBREPORT_DIR} + "subreport_2.jasper"
$P{SUBREPORT_DIR} + "subreport_2.jasper"
but i still keep on getting the same error and i dont know what i am doing wrong Below is my code
但我仍然不断收到同样的错误，我不知道我做错了什么下面是我的代码

It is because even though you have created a parameter called "subReport" it hasn't been used anywhere.
这是因为即使您创建了一个名为“subReport”的参数，它也没有在任何地方使用过。
<subreport>
<reportElement x="100" y="20" width="440" height="20" uuid="72f8c7c2-82ca-48d3-bb89-d5bb4846e1bc"/>
<subreportParameter name="qid">
<subreportParameterExpression><![CDATA[$F{qid}]]></subreportParameterExpression>
</subreportParameter>
<connectionExpression><![CDATA[$P{REPORT_CONNECTION}]]></connectionExpression>
<subreportExpression><![CDATA["Answers.jasper"]]></subreportExpression>
</subreport>
See? It is still "Answers.jasper" there in the main report. That is why it works fine in Jasper Studio. Let's change it to,
看？主报告中仍然是“ Answers.jasper”。这就是它在 Jasper Studio 中运行良好的原因。让我们把它改成，
<subreport>
<reportElement x="100" y="20" width="440" height="20" uuid="72f8c7c2-82ca-48d3-bb89-d5bb4846e1bc"/>
<subreportParameter name="qid">
<subreportParameterExpression><![CDATA[$F{qid}]]></subreportParameterExpression>
</subreportParameter>
<connectionExpression><![CDATA[$P{REPORT_CONNECTION}]]></connectionExpression>
<subreportExpression><![CDATA[$P{subReport}]]></subreportExpression>
</subreport>
I am pretty sure that I am not the one who taught you to use Jasper :) Let's hope it will work
我很确定我不是教你使用 Jasper 的人 :) 希望它能奏效

In MarkingScheme.jrxml change from
在 MarkingScheme.jrxml 中从
<subreportExpression><![CDATA["Answers.jasper"]]></subreportExpression>
to
到
<subreportExpression><![CDATA[$P{subReport}]]></subreportExpression>
Change the class adding the Answers.jasper including its path.
更改添加 Answers.jasper 的类，包括其路径。
parameters.put("subReport", "/edu/ijse/gdse41/ams/reports/Answers.jasper");
The path must be completed starting from the root context (/).
路径必须从根上下文 (/) 开始完成。
