Hi guys,
I think i am not clear in my question.Let me elaborate it.
I have a file inside my war file,,for ex: parallel to web-inf i have one folder ,,in that i have a file.I need to read it in my servlet.How can I achieve this.
servletContext().getRealPath("") is returning null in case of a war file.
Please suggest me any other way
Thanks
Use the classloader to load the file. Put the file or the subdirectory in your classes directory and then do something like:
InputStream is = getClass().getClassLoader().getResourceAsStream("subdir/file.txt");
This will look for the file as WEB-INF/classes/subdir/file.txt. If the file cannot be found the getResourceAsStream() method returns null.
Thanks a lot boss ,,It worked for now..
What if if i want to put a folder ,which is parallel to web-inf?how can i read that file?
Please suggest me,as i can not move that folder to classes/sub folder.
Thanks
well, you need to make the path to your web application configurable then. You can load a properties file in the way you know now, or you can put an init-parameter in your web.xml that contains the path to your WEB-INF directory so you can read that path and use it to create absolute paths to the files in the WEB-INF.
