Marichi Gupta updated TIKA-2908:
--------------------------------
Description:
I am using Apache Tika on Windows 10, jre 1.8.0_181, and I've imported Tika
using Maven with the following dependencies:
{{<dependencies> <dependency> <groupId>junit</groupId>
<artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope>
</dependency> <dependency> <groupId>org.apache.tika</groupId>
<artifactId>tika-parsers</artifactId> <version>1.21</version> </dependency>
</dependencies>}}
I have the code below for performing OCR using Tesseract (which I have
independently tested and know to be working):
public static void OCRTest() {
try {
BufferedImage im = ImageIO.read(new File(OCR_IMAGE));
{{TesseractOCRConfig config = new TesseractOCRConfig();}}
config.setTessdataPath("C:\\Program Files\\Tesseract-OCR\tessdata");
config.setTesseractPath("C:\\Program Files\\Tesseract-OCR");
{{ParseContext parseContext = new ParseContext();}}
parseContext.set(TesseractOCRConfig.class, config);
TesseractOCRParser parser = new TesseractOCRParser();
BodyContentHandler handler = new BodyContentHandler();
Metadata metadata = new Metadata();
try {
{{parser.parse(im, handler, metadata, parseContext);}}
System.out.println(handler.toString());
} catch (SAXException e)\{ e.printStackTrace(); }
catch (TikaException e) \{ e.printStackTrace(); }
} catch (IOException e)\{ e.printStackTrace(); }
}
I run into the following exception:
org.apache.tika.exception.TikaException: Failed to close temporary resources at
org.apache.tika.io.TemporaryResources.dispose(TemporaryResources.java:174) at
org.apache.tika.parser.ocr.TesseractOCRParser.parse(TesseractOCRParser.java:251)
at test.test.App.OCRTest(App.java:46) at test.test.App.main(App.java:30)
Caused by: java.nio.file.FileSystemException:
C:\Users\m\AppData\Local\Temp\apache-tika-2643805894084124300.tmp: The process
cannot access the file because it is being used by another process.
The tmp file is present in the Temp folder. I have the source code downloaded
and have stepped through it with the debugger - the error comes from attempting
to close the tmp file. On the Apache Tika forums, there is another post here
(https://issues.apache.org/jira/browse/TIKA-1732) where someone else has run
into the same exception, although with the AutoDetectParser and not Tesseract.
Their issue seemed to be a conflict in their imported jars, but I run into this
issue even with only the Apache Tika libraries installed. I have a feeling this
is a concurrency issue, but I can't pinpoint the conflict.
I don't run into this issue when using the Tika's AutoDetectParser, only with
the TesseractOCRParser. This is an important part of an application I'm working
on, so I would really appreciate any insights on how to proceed.
