I'm using iReport Designer 5.5.0, and was making a test JRXML. I added a text field with a value of $F{pricing_date} and added "pricing_date" to the list of "fields" on the Report Inspector panel (no properties or description set for the field).
The resulting JRXML has the "pricing_date" field defined:
<field name="pricing_date" class="java.lang.String"/>
And it has a text field with $F{pricing_date} as expected:
<textFieldExpression><![CDATA[$F{pricing_date}]]></textFieldExpression>
But... I get the error "Field not found : pricing_date" within iReport, and I get the same error during compilation.
I've compared this to other JRXML files within the samples provided, and it seems to match... what am I missing? Is there a setting somewhere to recognize field definitions?
I can see two possible reasons here.
If the report does not compile, the problem might be that the element in which you have placed the textField uses a different datasource than the one in which you have declared the field.
If it does not run, you might be missing the field in the object type of the datasource. Also, if you use JRBeanCollectionDataSource from java you have to have the getter for your field (declared as getPricing_date(){...}).
Hope this helps.

I am newbie to the ireport designer.This question may simple for you.I have tried to XML file as data source and it worked.The problem is All the fields are coming as java.lang.string. How to provide the field type in XML datasource.Is it possible to provide field type in XML file itself. Consider
<customer>
<name>obuli</name>
<age><22></age>
<subscriber>
<name>sundar</name>
<no_of_transactions>100</no_of_transactions>
</subscriber>
</customer>
Here the customer and subscriber are classes so i need to provide filed type com.test.Customer,com.test.Subscriber. I can achieve this by java bean datasource. But still i need the XML datasource way.
Is it possible to set the field type in XML datasource way ?
I do not think so. I also do not think you need that feature as reports only require scalar values. So just map the scalar values in your datasource to your scalar valued report fields.
You have to go on the XML code of your document and then search your field tag name, for example:
<field name="xxxx" class="java.lang.String"/>
change to Date type:
<field name="xxxx" class="java.util.Date"/>
I am using iReport - my first time using it - and I am trying to make a report that will involve passing a parameter to a subreport. I am not able to get that to work, so I did the following test:
I have a large query that grabs various Fields from my DB - when I preview the report these fields are being pulled and display (over and over, etc., a lot of stuff is being pulled).
I created a new parameter on the main report called "myparam". I made it's default value one of the fields that is being successfully pulled from my DB.
I created a textfield to display this param - the intent being it will echo the field that displays already in my report. If I can get it to do that, I figure I can get it to correctly "plug in" to my subreport.
The issue is - when I preview, I am asked to give the parameter a value - I choose default, which defaults it to the Field I set, which means it should now echo that field (aka I WANT it to echo that field). But it does not echo that field. Instead it just shows null over and over again. Here is a screenshot of what I am talking about
Here is the setup for my report:
Here is proof I've set the default value in my xml:
<parameter name="myparam" class="java.lang.String">
<defaultValueExpression><![CDATA[$F{TCORDERID}]]> </defaultValueExpression>
</parameter>
Here is a snippet of the report which is being generated incorrectly (aka myparam is not getting populated right).
THEY ARE BOTH STRINGS
From my understanding of parameters, they are passed to the report/subreport when it gets created. You have set the default value of the parameter to one of your fields, which has not been populated yet when the report gets generated.
I would suggest adding a simple subreport (which is the reason you want to use parameters anyway), remove the parameter on the main report, and add it to the subreport (with a text field to display it).
Now, add the Parameter to the subreport object in your main report. (This is under the Subreport properties section in iReport.
Name: The name of the Parameter in the subreport.
Expression: The field from your main report that will be passed to the subreport.
So your main report will have the following under the subreport detail:
<subreportParameter name="myparam">
<subreportParameterExpression><![CDATA[$F{TCORDERID}]]></subreportParameterExpression>
</subreportParameter>
And then the Parameter in the subreport:
<parameter name="myparam" class="java.lang.String">
<defaultValueExpression><![CDATA["No result"]]></defaultValueExpression>
</parameter>
I'm creating a jasper report using iReports 5.2.0 and I want to display the report file name in it.
Can't find any variable that has that information and I would like to get an alternative to pass it in the parameters.
How can I do it?
When you design your report, make a new PARAMETER named, for instance: NAME_REPORT.
After that, put a TextField in your report, for example, in your Title section, and
put as value of your TextField the parameter like a expression: $P{NAME_REPORT}
When you preview your report, ask you to give a value to this parameter and then, you see the title with the name
of your report file.
In your java code you will do somethink like that:
parameters.put("NAME_REPORT", "myreport.jrxml");
.....
JasperFillManager.fillReport(report, parameters, connection)
.....
How to use localized default values for parameters in iReport?
Using a $R{message.key} as the parameter default value has negative consequences in the "Read fields" functionality of iReport's SQL editor. More precisely, the following error is shown (after pressing the Read fields button in Report query dialog):
Sourced file: inline evaluation of: ``$R{message.key}'' : Attempt to access property on undefined variable or class name
Any way around this iReport problem?
Here is the image to illustrate the problem:
I think this is a iReport's bug.
You can temporary comment the defaultValueExpression expression and add the fields via the Report query -> Read fields button.
Or you can manually add the fields declaration.
This is iReport bug ! To solve this issue please follow the below steps.
Open XML File
Remove defaultValueExpression tag value.
JasperServer doesn't pass parameter from input control to the report for some unknown reason.
I defined a jrxml report with iReport 4.6 (even tried compatibility mode 4.0.1) using input parameter which works in iReport.
When I deploy the report on jasperserver 4.5 the response I get is "The report is empty".
Same report without parameter works also well.
Naturally I defined and attached input control with single-select query.
The value column and the visible column in input control is the same DB field I use as parameter in jrxml.
Query values as possible input are displayed fine, but when I choose one..."The report is empty"!!.
I tried simplifying the report but my parameter from input control just wont be passed through to render the report.
You must create the parameter in jasperserver too (not only in iReport), with same name.
In JasperServer, edit your report, define "Input controls" with same ids and go thru wizard, it should work now.
If you like to test first select "Always require in emergin window".
