Re: Solution for finding images in a WAR file

[Johan Åbrandt]

This solution may or may not work in existing servers, but it may also 
break. The problem is that ServletContext-getRealPath() is allowed to 
return null, for example if the content is served from a WAR.

String pathToFile = scntxt.getRealPath(/WEB-INF); // or whatever relative to 
web app root eg /images
String imagePath = file: + pathToFile;
org.apache.fop.configuration.Configuration.put(baseDir,imagePath);
as you can see, all my images are in web_app_root/WEB-INF.
The corresponding xml data file looks like this:
HTRelitiveRef HTRRKey=2 HTRRType=Picture HTRRID=/centurion.jpg HTRRLink= 
HTRRVisible=Fcenturion/HTRelitiveRef
I hope this saves others the problem of finding the solution across many posts!

Solution for finding images in a WAR file

[Rakesh Patel]

Hi,

I have found a solution that I think works (have not got access to a Unix 
environment to confirm this) but I did not hard-code any window/unix specific 
paths.

Here's a snippet of code I used:

ServletContext scntxt = this.getServletContext();
String pathToFile = scntxt.getRealPath(/WEB-INF); // or whatever relative to 
web app root eg /images

String imagePath = file: + pathToFile;

org.apache.fop.configuration.Configuration.put(baseDir,imagePath);

as you can see, all my images are in web_app_root/WEB-INF.

The corresponding xml data file looks like this:

HTRelitiveRef HTRRKey=2 HTRRType=Picture HTRRID=/centurion.jpg 
HTRRLink= HTRRVisible=Fcenturion/HTRelitiveRef

I hope this saves others the problem of finding the solution across many posts!

Thanks
