问题
I have successfully deployed a Java EE app to openshift with tomcat7. I deployed the war file and the welcome page loads but when my app tries to read an input .txt file to the application it can't find it. Any help would be appreciated.
My input files (2) are in the /WEB-INF folder in my project in eclipse.
This is my relevant code from my startup servlet:
public void doPost(HttpServletRequest req,
HttpServletResponse resp) throws ServletException, IOException {
// 11 lines of code setting strings according to input parameters
// from startup jsp which has forms for submitting operations
if ("Dates and Draws".equals(dates)) {
Powerball p = new Powerball();
Megamillions m = new Megamillions();
String path = this.getServletConfig().getServletContext().getRealPath("/WEB-INF");
p.appPath = path; // appPath is a class variable
m.appPath = path;
p.readnums(req, resp); // App is not reading input files in readnums methods
m.readnums(req, resp);
try {
// code for output using readnums methods, reading input files
} finally {
}
}
}
Powerball servlet readnums (same as Megamillions servlet readnums)
void readnums(HttpServletRequest req,
HttpServletResponse resp) throws ServletException, IOException , FileNotFoundException {
int i,j;
String Temp;
String [] Temp2 = new String [80];
String path = appPath + "/powerballnumbers.txt";
File file_check = new File (path);
if (!file_check.exists()) {
errorMessage = "Input file not found"; //This is what gets displayed
resp.setContentType("text/html");
PrintWriter out = resp.getWriter();
out.println("<html>");
out.println("<body>");
out.println("<h3>" + errorMessage + "</h3>");
out.println("<br><br>");
out.println("<form action=\"Startup\" method=\"get\"");
out.println("Go back to previous page: ");
out.println("<br><br>");
out.println("<input type=\"submit\" name=\"action\" value=\"Go Back to previous page\">");
out.println("</form>");
out.println("</body>");
out.println("</html>");
out.close();
return;
} else {
errorMessage = "";
}
draws = 1;
BufferedReader br = null;
br = new BufferedReader (new FileReader(new File(path)));
while ((Temp = br.readLine()) != null) {
if (Temp.isEmpty()) break;
Temp2 = Temp.split("\\s+");
int LastNonEmpty = -1;
for (i = 0; i < Temp2.length; i++) {
if (Temp2[i] != "") {
LastNonEmpty += 1;
Temp2[LastNonEmpty] = Temp2[i];
}
}
drawdate [draws] = Temp2 [0];
j = 1;
for (i = 1; i <= 5; i++) {
Temp = Temp2 [j];
nums [draws][i] = Integer.parseInt(Temp); // nums is class variable
j ++;
}
Temp = Temp2 [6];
xball [draws] = Integer.parseInt(Temp); // xball is class variable
draws++;
}
br.close();
draws--;
}
回答1:
Make sure that the unpackWARs attribute is set to true in server.xml, otherwise the war file will not be expanded and Tomcat will not be able to find your file.
