[Parameterizing orientation!]

I have seen this question being asked unsuccessfully before in this forum, but i'll ask anyways:

Any chance i can pass in the orientation for the report as a parameter?

[Parameterizing fonts]

This is the age-old question: how do i change the font used in the report dynamically? I have gone through the forum and found the following answers:

1. make as many lines as there are fonts and use printWhen to get the right font to print. This is a hack.

2. use a parameter or field to determine the font and change the <style> in the field. this one is still very cumbersome. if you have a hundred fields to show, putting the <expr> ? val1 : val2 with all the <style> stuff is tedious.

What's the laziest way to get this done :)

could i define <style>s at the beginning and then use the expression in 2. and switch between the styles?

Is there a cleaner way to do this through my datasource?

Thanks,

Nilesh

[passing parameters to subreport]

Folks,

I'm trying to pass a parameter into my subreport from the main report, and this is what i have:

in main report:

<subreport isUsingCache="true">

<reportElement x="25" y="5" width="501" height="128"/>

<parametersMapExpression>

$P{REPORT_PARAMETERS_MAP}

</parametersMapExpression>

<subreportParameter name="contractProxy">

<subreportParameterExpression>

<![CDATA[$P{contractProxy}]]>

</subreportParameterExpression>

</subreportParameter>

<subreportExpression

class="net.sf.jasperreports.engine.JasperReport">

<![CDATA[$P{GeneralInfoSubReport}]]>

</subreportExpression>

 

</subreport>

 

So i have tried passing the parameter as both an individual one, as well as the whoel param map.

 

In the subreport, i say,

 

<parameter name="contractProxy" class="..."/>

...

<textFieldExpression

class="java.lang.String">

<![CDATA[$P{contractProxy}.getValue("contractID")]]>

</textFieldExpression>

 

And i get the following error:

net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file:

1. com.sabre.airprice.ContractProxy cannot be resolved to a type

value = (java.lang.String)(((com.sabre.airprice.ContractProxy)parameter_contractProxy.getValue()).getValue("contractID"));

<------------------------------>

2. com.sabre.airprice.ContractProxy cannot be resolved to a type

value = (java.lang.String)(((com.sabre.airprice.ContractProxy)parameter_contractProxy.getValue()).getValue("contractID"));

<------------------------------>

3. com.sabre.airprice.ContractProxy cannot be resolved to a type

value = (java.lang.String)(((com.sabre.airprice.ContractProxy)parameter_contractProxy.getValue()).getValue("contractID"));

<------------------------------>

3 errors

 

 

The same textFieldExpression in my main report compiles without a hitch.

 

Any help is greatly appreciated.

Thanks,

Nilesh

[question about subreport sample]

Tim,

On an unrelated topic, I apologize for "decreasing your karma". i had no idea what those thumbs up/down icons were, and i thought it would give me info on those, and instead, it "decreased your karma", whatever that means. i had no intention of doing that.

[question about subreport sample]

Tim,

then i must be missing something. My masterreport.jrxml is only 110 lines long, so it doesn't have line 195.

Also, you speak of a productReport.jrxml, which wasn't in the zip file i downloaded.

i have attached my subreport sample zip file.

could you somehow send me the zip you have? [file name=masterreport.zip size=48211]http://www.jasperforge.org/components/com_joomlaboard/uploaded/files/masterreport.zip[/file]

[question about subreport sample]

Folks,

I'm looking at the samples, and i was checking out the subreports sample, and either i don't understand how it works, or something is missing or both.

The zip file contained the following files:

MasterReport.html

MasterReport.jrxml

MasterReport.pdf

 

Shouldn't there be a jrxml or something for the subreport part? basically i can't figure out where the subreport text is coming from. e.g.

in the left column it says, "Products ordered by people in <City>", and on the right side it says, "Addresses in <city>", but i don't see this text in the MasterReport.jrxml.

 

Thanks,

Nilesh
