How to read a file from file system in AEM

Is there a way to read a file as Java.IO.File in AEM, because I need to pass a Java file object to a google api method and file is present on my computer file system. I tried various method like adapting a resource to File or getting file from BundleContext, but non of these worked for me.

Actually to get a GoogleCredential object I need to pass a service account email id, a json factory object and a .p12 file as Java.io.File object (which google provide for authentication).But I am not able to read the .p12 file from my file system or from project jar or or from content hierarchy.

Please suggest how can I read a file that is present on my file system in aem project.

Thanks in advance.

Hi 

Please red the following article:-

How to read an external file in CQ

Use Case: You want to read something from external file

Solution : There are multiple ways you can do this I will mentioned two of them here,

1) You can put them under /resources folder under /src/main for example if you want to read a file called "test.txt" then you can put file under /src/resources/<any-sub-foler>/<file-to-read>

Then use following code to read file 
InputStream stream = getClass().getResourceAsStream("<file-to-read>");
in above case it would be InputStream stream = getClass().getResourceAsStream("/test.txt");

Good practice is to follow convention, For example if your source code is under /src/main/java/com/test/mytest/Test.java Then your resource should be in location /resource/com/test/myTest/<Your File>

Then you can use something like


InputStream in = Test.class.getResourceAsStream("<Your File>");


2) You can put file in repository (Any repository location is file) and use Node data as stream to read.

then use following code,
InputStream in = node.getNode("jcr:content").getProperty("jcr:data").getStream();

I hope this would help you.
