Using Tess4J in war (web app) on Application server (Payara, glassfish,..)

[scrmtrey91]

Hello there.

I am experimenting with tess4j for about 2 weeks in total. When i run my junit test case, everything is good. Also it gives great results.

Now i implemented it into an war application and deployed it to payara app server.

If i dont run any OCR with tess4j (not creating instance), the war can be redeployed infinity number of times. But when i do run OCR (also working great as expected from tests) then i cannot redeploy the app any more via IDE (IntelliJ).

• it uses constantly 20% of the CPU after OCR , even in idle condition when OCR finished OK with the ocr text.

Error from redeploy:
[2019-11-25 01:22:53,352] Artifact doksis-ui:war exploded: java.io.IOException: com.sun.enterprise.admin.remote.RemoteFailureException: Error occurred during deployment: Exception while loading the app : EJB Container initialization error. Please see server.log for more details.

And there is no additional errors in server.log about this issue.

Any idea ?

<dependency>
      <groupId>net.sourceforge.tess4j</groupId>
      <artifactId>tess4j</artifactId>
      <version>4.4.1</version>
</dependency>

• jai-imageio-core (1.4.0) and pdfbox (2.0.17)

Using like this:

Tesseract1 instance = new Tesseract1();
instance.setDatapath("C:\\Users\\user1\\tessdata"); 
instance.setLanguage("slv");
String result = instance.doOCR(img2ocr);
