Programatically implementing I18n!!!

Hi All,

I have a .rptdesign & .properties (for i18n) files. Now, I want to know that how can I access these .properties file to localize the text in .rptdesign at runtime. I want this to be done using either Engine api or Design api.

Could I use ResourceBundle? Then please provide me to integrate ResourceBundle with BIRT api.

Thanks in advance.

Hi Dhaval,

If you are trying to change out the properties file at runtime, you can do this in the beforeFactory method with syntax like below:

var rr = reportContext.getReportRunnable();
rr.designHandle.setProperty("includeResource", "MyResources");

You can also assign the textkey that gets evaluated in the name/value pait to a label by using:

onPrepare() method of label...
this.textKey = "welcome";

or from anywhere else...
reportContext.getReportRunnable().getDesignInstance().getLabel("GoodbyeLabel").textKey = "goodbye";

Thanks vdodson for you reply! I have one more thing. Can we do I18n by using ReportEngine api. If it is possible then please help us.

I have inserted a Group field in the crosstab which is having few entries, now I have got their mapping in resource files (.properites) for each langauge & not in designer. So, how could I do that mapping using only ReportEngine api, i.e. IRunTask or IRenderTask or IRunAndRenderTask.

Again thanks in advance.

If you are trying to set the location of the properties files at runtime using the REAPI, then you can call 
config.setResourcePath("C:/work/eclipse/BIRT_221/resources"); 
from the EngineConfig. 
 
You can also assign the locale at runtime with something like: 
task.setLocale(ULocale.FRENCH); 
 
You will need to get a handle on the report design if you want to start assigning resource keys to individual elements like below. 
 
IReportRunnable design = null; 
ReportDesignHandle dh = null; 
 
design = engine.openReportDesign("C:/workspace_221/birt/Localization.rptdesign"); 
dh = (ReportDesignHandle) design.getDesignHandle(); 
 
LabelHandle mylabel = (LabelHandle) dh.findElement("LastLabel"); 
mylabel.setTextKey("welcome"); 
 
... and in your case where you want a dynamically assigned textkey based on the group there may be some extra work. There may be a better way, but you can use the Mapping feature to assign a resource key. I've created an example reportdesign that does this (link below) and if you want to assign these mappings using the REAPI, it would look something like below. 
 
ReportItemHandle dataitem = (ReportItemHandle) dh.findElement("OfficeGroupField"); 
MapRule mr = StructureFactory.createMapRule(); 
mr.setTestExpression("row["OFFICECODE"]"); 
mr.setOperator(DesignChoiceConstants.MAP_OPERATOR_EQ); 
mr.setValue1("7"); 
mr.setDisplayKey("7"); 
 
PropertyHandle ph = dataitem.getPropertyHandle(StyleHandle.MAP_RULES_PROP); 
ph.addItem(mr);
