Hi all,

I'm trying to open and read a resource file that is included in a pod, but I'm getting this output from the code below:

File contents: [Hello World!]
File exists: true
sys::UnsupportedErr: ZipEntryFile.open
  fan.sys.ZipEntryFile.open (ZipEntryFile.java:134)
  fan.sys.File.open (File.java:378)
  trypod::Main.main (Main.fan:7)
  java.lang.reflect.Method.invoke (Method.java:498)
  fan.sys.Method.invoke (Method.java:573)
  fan.sys.Method$MethodFunc.callOn (Method.java:244)
  fan.sys.Method.callOn (Method.java:139)
  fanx.tools.Fan.callMain (Fan.java:185)
  fanx.tools.Fan.executeType (Fan.java:147)
  fanx.tools.Fan.execute (Fan.java:41)
  fanx.tools.Fan.run (Fan.java:308)
  fanx.tools.Fan.main (Fan.java:346)

Main.fan

class Main {
  Void main()
  {
    echo( "File contents: " + File( `./src/trypod/res/file.txt` ).open.readAllLines )
    echo( "File exists: " + Pod.of( this ).file( `fan://trypod/res/file.txt` ).exists )
    echo( Pod.of( this ).file( `fan://trypod/res/file.txt` ).open.readAllLines )
  }
}

The file called file.txt exists in the res/ directory and I have included this line in build.fan

resDirs  = [`res/`]

Can anyone please let me know how this is done, or what I'm doing wrong here?

Hey LightDye, good to see you back!

I believe the clue is in the err msg, "sys::UnsupportedErr: ZipEntryFile.open" and that you cannot use open() on a Zip file entry.

So instead, try using the read methods on the File object directly:

echo( this.typeof.pod.file(`/res/file.txt`).readAllLines )

Hope this helps,

Steve.

Thanks Steve! It worked. I can't believe it was so simple.

Just a note: the sys::File.open method opens as a random access file (just like java.io.RandomAccessFile). In general its always better to open as a stream if you can using File.out if you don't need random access.

Thanks Brian for clarifying the difference between open and out.
