Java - HtmlUnit - Unable to save HTML to file (in some cases)

Question

Hi all,

I am having intermittent issues saving the response HTML in HtmlUnit.

Caused by: java.io.IOException: Unable to save file:C:\ccview\PP50773_4.0_walter\TSC_hca\Applications\HCA_J2EE\HCA\target\HtmlUnitTests\single\1\com\pnc\tsc\hca\ui\test\SiteCrawler\crawlSiteAsProvider\10.SiteCrawler.crawl.html

Now, the parent directory exists and some other files have already been written to the directory. Looking at the filename, I don't see anything that would stand out as a red flag indicating the filename is bad.

What can I do to correct this error?

Thanks,

Walter

Answer 1

Well, you are well within the maximum path length. The exception trace clearly believes it is a path problem. I would try some additional tests to help isolate the problem. Check the directory before writing with: File.exists(), File.isDirectory(), File.isWritable(). Similar checks on the file itself. May want to see if the disk is full too.

If you can get a little more information on the source of the problem, we can get it resolved.

Thanks,
