How to read properties file inside jar?

Question

I have a config.properties file under the package com.abc.properties. From one of the java class present in com.abc.util, I need to read the property file. Both the files are present inside jar. I have tried using

fs = new FileInputstream(VerifyFolderStructure.class.getResourceAsStream("com/abc/properties/config.properties"));

But it doesn't seem to work. Please help.

P.S: VerifyFolderStructure is my java class from which I need to load the properties file.

Solution 1

To obtain the stream you don't need FileInputStream at all. You can get the properties' file stream like this

InputStream is = VerifyFolderStructure.class.getResourceAsStream("/com/abc/properties/config.properties");

Solution 2

I think you need to add "/" in the front of you path.if you don't add "/" that means the properties is located in the same packages path as VerifyFolderStructure class.

Also I have tried fs = new FileInputstream(VerifyFolderStructure.class.getResourceAsStr‌​eam("../properties/c‌​onfig.properties")); this also doesn't seem to work.

Are you getting some error? And, what do you mean by VerifyFolderStructure is my java class from which I need to load the properties file.

Well, you won't be able to use it as ` FileInputStream` for starters, because it's not a File if it's inside the jar.

Can you please suggest an alternative? I tried using InputStream as well.

"/" in front of path means load properties from the classpath.

I tried that also. After adding that I'm getting a FileNotFoundException. Otherwise I'm getting a NullPointerException

does VerifyFolderStructure in the same path of you file?

VerifyFolderStructure is under the package com.abc.util
