Read File Present inside Java and J2EE Project<\/figcaption><\/figure>\n

Consider above project hierarchy, we want to read the file “hibernate.cfg.xml”\u009d in “TestMain.java”\u009d. If we try to get the absolute path using “(new File(“”)).getAbsolutePath()<\/strong>“\u009d then it will give the path of eclipse in case we are using eclipse or tomcat from where the application is running. This problem occurs mainly in file upload functionality.
\nBelow code can be used to solve this type of problem.<\/p>\n

\npackage com.G2.servlets;\nimport java.io.BufferedReader;\nimport java.io.InputStream;\nimport java.io.InputStreamReader;\n\npublic class TestMain {\n\t\/**\n\t * @param args\n\t *\/\n\tpublic static void main(String[] args) throws Exception {\n\t\tTestMain testMain = new TestMain();\n\t\tInputStream st = testMain.getClass().getResourceAsStream("\/hibernate.cfg.xml");\n\t\tBufferedReader in = new BufferedReader(new InputStreamReader(st));\n\t\tString line;\n\t\twhile((line = in.readLine()) != null)\n\t\t{\n\t\t\tSystem.out.println(line);\n\t\t}\n\t}\n}\n<\/pre>\n
Now consider below situation:<\/p>\n
\"Read<\/a>
Read File Present inside J2EE Project<\/figcaption><\/figure>\n
You need to read the file present in folder “WebContent”\u009d. To read the file, we can use here Servlet Context<\/strong>.<\/p>\n
\nInputStream st= getServletContext().getResourceAsStream("\/css\/style.css");\n\t\tBufferedReader in = new BufferedReader(new InputStreamReader(st));\n\t\tString line;\n\t\twhile((line = in.readLine()) != null)\n\t\t{\n\t\t\tSystem.out.println(line);\n\t\t}\n\n<\/pre>\n","protected":false},"excerpt":{"rendered":"
