iReport JRValidationException field not found

问题


I'm trying to make my first steps with JasperReports and iReport. Recently I solved a problem with Database Connection in this post. After that I created another successful connection to a MySQL DB just to reinforce the knowledge; I made a query but now I'm getting another error related -I suppose- to the query itself or something like that.

The situation

When I try to create a Report query the fields (table columns) are retrieved and it's type is recognized correctly but the data (rows) gives me an error with the message

Error: net.sf.jasperreports.engine.JRException: Error excecuting SQL statement for: data

The error is shown in the screenshot below:

Then, when I try to preview the report with the fields of the query I get the following error:

net.sf.jasperreports.engine.design.JRValidationException: Report design not valid : 
    1. Field not found : idaddress
    2. Field not found : city

In the jrxml file the fields are defined properly as I saw in this other post as follow:

<subDataset name="MyDataset" uuid="b9d7b569-d19e-451e-8a15-c558918e1698">
    <queryString language="SQL">
        <![CDATA[SELECT
 address.`idaddress` AS address_idaddress,
 address.`city` AS address_city
 FROM
 `address` address]]>
    </queryString>
    <field name="address_idaddress" class="java.lang.Integer"/>
    <field name="address_city" class="java.lang.String"/>
</subDataset>

The project

The complete jrxml file is this:

And the connection's config is this:

Note: Yes, the server has no password, it's just a testing environment...

Some attempts

I tried the other answers in the same post but none of them work for me. Last I tried changing the connection URL adding port and user but the error remains the same.

Don't know why below the <subDataset>element I have the following XML:

<queryString>
    <![CDATA[SELECT
 *
 FROM
 `address` address
 ORDER BY
 city ASC]]>
</queryString>
<field name="idaddress" class="java.lang.Integer">
    <fieldDescription><![CDATA[Address table ID]]></fieldDescription>
</field>
<field name="city" class="java.lang.String">
    <fieldDescription><![CDATA[The city]]></fieldDescription>
</field>
<group name="city">
    <groupExpression><![CDATA[$F{city}]]></groupExpression>
</group>

Looks the same as the <subDataset> but it's there. I didn't wanted to remove as this is generated by iReport, so I assume it's correct.

So the question is: what am I missing here? What can I try to solve this? where can I look for some clue?

Thanks in advance for your answers.


回答1:


You have some confusion about how Jasper Report works, the difference between main datasource and a subDataset and when using them you need to reference the fields related to the datasource that you are using.

To clear some confusion:

  • The main datasource will execute and jasper report will iterate (repeat) the detail band for each record.

  • The subDatset is another datasource that you can pass to a component.

The solution to your report is to either use only the main query (delete the jr:table component and its subdataset) or if you like to use the jr:table, have a main datasource that returns only 1 record and then pass the subdatasource and the connection to the jr:table component

Example using textField's in the detail band

Note: No more table component and subdatasource, the fields of the main datasource are referenced directly in the textField's. The detail band will be repeated as many time as there are records in your query.
