Internal exception opening a MsWord document. #120

Closed cvalde closed 6 years ago

cvalde commented 6 years ago

Hello, with this simple code var fn = <some .doc file> var textExtractor = new TextExtractor(); var wordDocContents = textExtractor.Extract(fn); I'm translating from Spanish:

Extraction failed. Exception in initializer of type 'org.apache.tika.metadata.Metadata'. Cannot convert object type 'java.util.PropertyResourceBundle' to type 'sun.util.resources.OpenListResourceBundle'.

I can send you an example project but since it's extremely simple (the same basic example shown at https://github.com/KevM/tikaondotnet) I think it would be better if I send you the file. I would rather avoid posting such a file in a public place because it's from my job.

Thanks. Claudio.

I should correct myself. I was able to reproduce the error with a simple .docx document that I can send on request, but the issue seems to be of another type. The code var textExtractor = new TextExtractor(); var webPageContents = textExtractor.Extract(new Uri("https://google.com")); produces exactly the same exception Cannot convert object type 'java.util.PropertyResourceBundle' to type 'sun.util.resources.OpenListResourceBundle'. Could the operating system´s regional settings be the culprit? My Windows is set to Chile, Spanish. Thanks.

Hmm we have a unit test which basically does the same thing. Sounds like a IKVM problem. This post sounds similar. Maybe ensure you have all the required IKVM assemblies present in your application bin directory.

Thanks for your answer. I used Nuget to install TikaOnDotnet.TextExtractor and it did all the job. Is there any listing that I can read to verify IKWM has all the files? I'm using VS 2015 with .net 4.5, not sure how to overcome this error.

We've had problems in the past with some required assembly not being included with people's deployments. There are a lot of IKVM assemblies and you'll need to include most of them when you deploy your application.

Based on your other issue #121 you are on the right track. You can build and run the tests to see text extractor work. It is easy to add a test for the particular document you are having problems with. Let me know if I can help.

I was able to make TikaDN work with a simple Winforms project. Not sure what happened with the original WPF application. I will try in a few days more again.
