How can I access values in a Bean?

2004-06-03 02:47

Hello,

 

I need to internationalize my reports and have to use a bean with the right words in it. So I put the bean in the parameters and try to access it. My problem is that I can not access the values inside my bean!!! I have tried this:

 

<textField isBlankWhenNull="true">

<reportElement x="0" y="40" width="50" height="15"/>

<textElement textAlignment="Left">

<font reportFont="Arial_Bold"/>

</textElement>

<textFieldExpression class="java.lang.String">

<![CDATA[$P{LangBean}.getKontrakt_Id()]]>

</textFieldExpression>

</textField>

 

But I allways get this error:

 

C:eclipseworkspaceReportGeneratorUmsaetze_FX_Termin.java:184: ')' expected

value = (java.lang.String)($P!{LangBean}.getKontrakt_Id());

 

Please help because I really need this feature.

 

Greetings

Sven

Hi!

 

Remove the "!" from value = $P!{LangBean}.getKontrakt_Id(). The "!" has special meaning for query ... see manual.

Hello,

 

I have removed the "!" from my .xml file. I just put in the wrong error message. Thank you for your response. This is the right one:

 

C:eclipseworkspaceReportGeneratorUmsaetze_FX_Termin.java:184: cannot resolve symbol

symbol : method getKontrakt_Id ()

location: class java.lang.Object

value = (java.lang.String)(((java.lang.Object)parameter_LangBean.getValue()).getKontrakt_Id());

 

I really need a solution for the problem because it is a requirement.

 

Thank you.

 

Sven

You have got your class types all out of whack.

 

First, you need to identify what class you really want to be using (String, Object, your own bean class?).

 

Second, you need to get the Parameter class type and the TextField class type in sync with each other (the same value for the class parameter).

It looks like you've declared your parameter as java.lang.Object.

 

Check that you have the right class (fully qualified name) when you declare the parameter:

<parameter name="ReportTitle" class="<your-fully-qualified-class-name"/>

 

Also check that you've set this parameter.

parameters.put("LangBean", new LangBean("Working"));

 

I created a simple LangBean with just a "status" field and I've modified the DataSourceReport sample ... and it is working. You have the template attached.

 

Lucian.

RE: How can I access values in a Bean?

Hello,

 

the idea with the types was the right one. To make the bean work 2 steps are nessecary:

 

1. The class type was the problem.

<parameter name="LangBean" class="reports.LangBean"/>

 

2. This prints the value.

<textField isBlankWhenNull="true">

<reportElement x="0" y="40" width="50" height="15"/>

<textElement textAlignment="Left">

<font reportFont="Arial_Bold"/>

</textElement>

<textFieldExpression class="java.lang.String">

<![CDATA[$P{LangBean}.getKontrakt_Id()]]>

</textFieldExpression>

</textField>

 

Thank you very much. Now all my imediate problems are solved and I can use Jasperreports.

 

Greetings

Sven
