I do something like this now. In my struts app, I pass in the MessageResources as a parameter to the report and the scriptlet saves it in the initialization. On the report, all the static text fields are actually regular text fields that read resources from the MessageResources using a call to the scriptlet.

As far as the actual data printed, there's very little you can do. Values are generally represented in a database as currency in a local exchange, so that's pretty static. If you wanted to change that, you'd need to do a scriplet that took the value and an exchange rate, performed the calculation and wrote the output using a formatter. That's my next step to take.

I create a Hashtable of formatted message resources like this :

 

Object[] errormessageargs = {};

Hashtable messages = new Hashtable();

mf = new MessageFormat(rb.getString("report.header.project" ));

messages.put("PROJECTHEADER",mf.format(errormessageargs));

mf = new MessageFormat(rb.getString("report.header.user" ));

messages.put("USERHEADER",mf.format(errormessageargs));

mf = new MessageFormat(rb.getString("report.header.printer" ));

messages.put("PRINTERHEADER",mf.format(errormessageargs));

mf = new MessageFormat(rb.getString("report.header.printtime" ));

messages.put("PRINTTIMEHEADER",mf.format(errormessageargs));

mf = new MessageFormat(rb.getString("report.header.documenttitle" ));

messages.put("DOCUMENTTITLEHEADER",mf.format(errormessageargs));

mf = new MessageFormat(rb.getString("report.header.type" ));

messages.put("TYPEHEADER",mf.format(errormessageargs));

mf = new MessageFormat(rb.getString("report.header.pages" ));

messages.put("PAGESHEADER",mf.format(errormessageargs));

mf = new MessageFormat(rb.getString("report.header.pagecost" ));

messages.put("PAGECOSTHEADER",mf.format(errormessageargs));

mf = new MessageFormat(rb.getString("report.header.totalcost" ));

 

 

Then I accept them into my report like this:

 

<!-- Localized messages -->

<parameter name="messages" class="java.util.Hashtable"/>

 

 

Then I access them like this

 

<textField>

<reportElement positionType="FixRelativeToBottom" x="1" y="20" width="136" height="15">

</reportElement>

<textElement>

<font fontName="Arial" size="10" isBold="false"/>

</textElement>

<textFieldExpression><![CDATA[(String)($P{messages}).get("REPORTINGTITLE")]]></textFieldExpression>

</textField>

 

 

This allows me to provide I18N strings, currencies and dates since they are being formatted in my servlet which has proper access to the browsers Locale object.

 

This for me is being done in a struts Action and I am using the JRBeanCollectionDataSource based reporting stuff, it works great for us!

Note: by the time any data gets into the Hashtable its been cast to a String to make life easier in the Jasper Report. So if I have a formatted currency I get it into a string before I add it in. This is all just for display so this concept works fine.

       I want to print some unicode character(of Hindi language) as output.For that i set following test element for field "name" in my .jrxml file

 

<textElement>

<font fontName="Mangal" size="12" isBold="true" isUnderline="false" pdfFontName="mangal.ttf" pdfEncoding="Identity-H" isPdfEmbedded="true"/>

</textElement>

<textFieldExpression class="java.lang.String"><![CDATA[$F{name}]]></textFieldExpression>

I have set pdfFontName as mangal.ttf ,and i am passing the unicode value (for hindi name) from my java code.

Even I save my java code  in UTF-8 formate and compile it with the UTF-8 encoding in eclipse IDE. 

Still that hindi word didnot not disply.

Plz give me some short example how can i display hindi word providing its unicode dynamicaly into my jasper report.Which setting i want to apply to display the field in hindi?

Thank you in advance...
