Reg. getRealPath("/") _ How does the result of this method differ in Tomcat 7 and Tomcat 8
Hi Team,
Using this method
getServletContext().getRealPath("/")
returns '\' at the end when I run my project in Tomcat 7 whereas it is not
working as such in Tomcat 8.
For example,
In Tomcat 7 it returns as "D:\Tomcat\webapps\project\"
In Tomcat 8 it returns as "D:\Tomcat\webapps\project"
At present the project is in production so, I am unable to change the code
in every part(where i use getRealPath("/")). Is there a way/setting in
tomcat level configuration to make it resolved.
Additional information,
Tomcat version : 8.0.14
OS : Windows server 2008 R2 standard
System Type: 64 bit operating system
Thanks,
Sasi Kumar M.

It looks to me like you're not going to be able to do this without some
code changes (or just stay in TC 7 for now). Either check for the
existence (or not) of the trailing "\" and fix the path string
accordingly, or since the file you're trying to read is inside your
context, build the name from the context path rather than the real path.
Either way needs code changes, but the second one is more portable
than the first option.

1. Do you really need a file?
ServletContext.getResourceAsStream() provides an InputStream
ServletContext.getResource() provides an URL
Both work even if unpackWARs=false.
2. java.io.File can perform path arithmetics regardless of
terminating '/' in parent path,
new File(parent, child)

Konstantin Kolinko

Any application depending on getRealPath() is inherently flawed. There is no guarantee in the servlet spec that getRealPath() will ever return anything other than null, since there's no guarantee that deployment occurs within the file system. It's unfortunate that this interface still exists; it should have been deprecated long ago.
The proper way to read data packaged within the webapp is to use ServletContext.getResourceAsStream(), which is required to work regardless of the packaging and deployment.

Hi André Warnie,
Great thanks for your response.
But here, I am not writing anything inside the web application.
1. I have a flat file in the web application and it has some configurations
details, which I use for the project.
2. Therefore, we are trying to read the configuration detail from that file.
3. And as I mentioned earlier it works fine until tomcat 7. Now, we are
planning to upgrade to tomcat 8.0.14 and facing this issue.
Please let me know about your valuable thoughts/suggestions.
Thanks,
Sasi Kumar M.

Hi.
I do not know the answer to your question.
But maybe now would be a good time to examine why you are using
getServletContext().getRealPath(), and to browse the following thread for
some good
reasons not to be doing that.
