How to create a multi language report?

Question

I want to create a document, which prints in more than one language, based on the Locale.

I have created 2 resource bundles, one in English and one in Chinese, but I am not sure how to use them.

Answer 1

Here is the sample of how to implement internationalization support for JasperReports.

The main idea is to use special expression $R{} for localizing text and images.

The sample for images:

<image scaleImage="Clip"> 
    <reportElement positionType="Float" x="20" y="20" width="100" height="50"/> 
    <imageExpression class="java.lang.String"><![CDATA[$R{image.flag}]]></imageExpression> 
</image>

The samples for text (the $R{} syntax):

<textField isBlankWhenNull="true"> 
 <reportElement x="20" y="100" width="530" height="20"/> 
 <textElement/> 
 <textFieldExpression class="java.lang.String"><![CDATA[$R{sampleString}]]></textFieldExpression> 
</textField> 

or (the msg() method):

text.message=The program picked up {0} as a random number.

<textField isStretchWithOverflow="true" isBlankWhenNull="true"> 
 <reportElement x="20" y="210" width="530" height="20"/> 
 <textElement/> 
 <textFieldExpression class="java.lang.String"><![CDATA[msg($R{text.message}, $P{number})]]></textFieldExpression> 
</textField>
