"The path for the output file contains an error and could not be opened. Please check again!"

I don't understand why I am getting this error since I am using the same directory for both the --images and --annotations params and I am supplying the absolute filename in both cases.

2.4.9 is stone age
how is that related to java ? (the annotation tool is a c++ exe)

As author of the tool, I encourage you to use at least latest 2.4 branch. The tool had issues, these were reported and fixed, but you probably running the broken version still.

also make sure the parameters are passed correctly like --images=/data/text.txt --annotations=/data/annotations.txt without any spaced between the = sign and the contents.

People tend to do this wrong from time to time.

Sorry for not getting back, I was on my hols.

The solution for the problem is to use -images=/data/text.txt and -annotations=/data/annotations.txt, i.e. a single horizontal dash (-) in front of the key words.

That is not correct ...its single dash for a shortened parameter but double dash for normal ones. Can you check this again, because it works on all OS and configurations here.
