Hi, I want to read a file in EJB in bean method. I have the file (error.prop) in the ejbmodule/META-INF folder.
When I right click on the ejb and click "Run on Server" to test it, I get an Exception.Basically,the call fails in File.exists() method. Below is the code.Can anyone please tell me the problem in the below code.
I know I can use ResourceBundle to load the file.But,want to know the problem in the below code.The code looks ok to me.I tried putting the file directly in ejbModule folder.No luck. I also tried setting strMessageFile in the below code to "error.properties", "//error.properties" etc., It did not work.
First of all you have to understand that performing IO operation within your ejbs is not recommended and ejbs specs strictly forbid it. You might consider using the ResourceBoundle class or the less orthodox approach of calling the ClassLoader.getResourceAsStream() method. On the other hand although is been a while since I looked at the io api, it occurs to me that opening a file which is inside of a jar module (which in turn could be inside of a ear file) is not going to be easily done using io api. I believe you should open the jar file first, un-jar it and finally opening the properties file. Again io is not suitable for this task in my opinion you should better try using another approach. Regards.
