Get the resource directory in AEM

[shekhart6405668]

Hi Guys,

I am using the AEM 6.2. and new to AEM. Can some one suggest me how to  get the real path of the resource directory? i.e "src/main/resources".

Hello,

Not related to your question. Just want to let you know that you should start upgrading to AEM 6.5 since the core support of 6.2 has ended.

Hi shekhart64009905​,

Do you want to read a file included in resources section?

[mohitaem]

Shekhar is trying to access "src/main/resources" folder from the java code. He want to create, write, read and delete the file in the resources folder. Since we install the java project as bundle its not possible to hardcode the path so he is finding it difficult to read the path of "src/main/resources".

If you want to manipulate the files using Java then you can use relative paths instead and take advantage of ClassLoader.

e.g. to read a file test.json inside test-folder under src/main/resources and get its contents in Java code:

InputStream is = getStreamFromResources("test-folder/test.json");
printFileContents(is);

If not inside a folder:

InputStream is = getStreamFromResources("test.json");
printFileContents(is);

Methods:

private static void printFileContents(InputStream inputStream) throws IOException {
  StringBuilder textBuilder = new StringBuilder();
   try (Reader reader = new BufferedReader(new InputStreamReader
  (inputStream, Charset.forName(StandardCharsets.UTF_8.name())))) {
   int c = 0;
   while ((c = reader.read()) != -1) {
  textBuilder.append((char) c);
  }
  }
   jsonString = new String(textBuilder);
   LOGGER.info(textBuilder.toString());
}
// get file contents as stream from classpath, resources folder
private InputStream getStreamFromResources(String fileName) {
  ClassLoader classLoader = getClass().getClassLoader();
  InputStream is = classLoader.getResourceAsStream(fileName);
   if (is == null) {
   throw new IllegalArgumentException("file is not found!");
  } else {
   return is;
  }
}

This is how my folder structure looks like:

Hi Ram,

Thanks for response on this. Now file reading and writing inside test-folder make sense. But how can we listed all file inside the test-folder.

If you want to access the files in the JAR file during runtime, you can use the "regular" API you would always use in java, this is not specific to AEM. On the other hand, I doubt that the test classes are part of the resulting JAR file.
