Get Server Name in Script

I need to determine the server/host name.
I am in a DataSource beforeOpen script function. But would also need it in the Property Binding Script as well.

var xml_url = 'http://'+reportContext.getAppContext().get("ServerURL")+'/';

I have also tried reportContext.getAppContext().get("SERVER_URL")

This keeps showing http://null/. What am I doing wrong? How do I get list of all AppContext IDs.....

You can see the keys in the AppContext map by putting this into a dynamic text box in your report.

reportContext.getAppContext().keySet().toArray().join("

");

And with this one, you can see the values.

reportContext.getAppContext().values().toArray().join("

");

If you're not using BIRT Designer Pro, you should be able to use reportContext.getHttpServletRequest().getServerName(); to get the server name.

Hi
 
I know its an old thread but I am also trying to achieve same thing in property binding to use the datasource on the basis of domain.
 
I used both methods and both works fine when I run the report from designer but when I try to run the report in iHub application or through my own application where the integration is done via javascript api I am getting HttpServeletRequest as null due to which it gives exception that cannot call getServerName on null.
 
Here what I am doing.
<pre class="_prettyXprint _lang-js">
if(reportContext.getHttpServletRequest()!=null && reportContext.getHttpServletRequest().getServerName().indexOf('dev') != -1 ){
"jdbc:mysql://development/ignite"
}else {
"jdbc:mysql://production/ignite"
}

or

if(reportContext.getAppContext().get("BIRT_VIEWER_HTTPSERVET_REQUEST").getServerName().indexOf('dev') != -1 ){
"jdbc:mysql://development/ignite"
}else {
"jdbc:mysql://production/ignite"
}

</pre>
We are using iHub version 3.0.

If you are trying to create a configuration where the report connects to a different database between development and production on iHub, the best solution is to use a connection profile for the data source.
 
Then you will have a different version of the connection profile deployed to each environment with the respective credentials for that environment.

But I have only one instance of iHub running which is being used by both test and dev environment.
 
I have created a common library which contains datasource information and is used by all reports and I tried httprequest method but it didn't work.
 
If i go for connection profile then it will be binded statically to the datasource i guess.

I think you may need to consider an alternate method.
 
Even if httpServeletRequest was working, you will get the same response for both since they are both on the same server.

Actually I have one iHUb Server which is being accessed by both my dev and production applications.
I have been using actuate javascript API for integration. So isn't the httpServeltrequest is going to be of the server on which application is deployed as in the report gets embedded into the my application.
 
So when I try to access iHub via dev then I will get Dev url and when from Production the I will get Production url.
 
And what other ways are possible too have dynamic datasource based on server accessing a report

JFreeman

Gotcha, that is a bit different that I had thought from you previous description.
 
An alternative that comes to mind is you could add a hidden parameter to your reports that is used to determine if it should connect to Dev or Prod and when you call the report with JSAPI you set this parameter differently depending on which environment is calling the report.

Nikhil Mahajan

Actually, I also thought of passing a hidden parameter from the application but I want to skip it to make it independent of application as this will be a redundant step at wherever I am integrating a report from iHub into my application
