STORESCU fails on opencv_java

[jssuttles]

Describe the bug When using the storescu process, we get the following error: Exception in thread "main" java.lang.UnsatisfiedLinkError: \<file path>\opencv_java.dll: Can't find dependent libraries at java.base/jdk.internal.loader.NativeLibraries.load(Native Method) at java.base/jdk.internal.loader.NativeLibraries$NativeLibraryImpl.open(NativeLibraries.java:388) at java.base/jdk.internal.loader.NativeLibraries.loadLibrary(NativeLibraries.java:232) at java.base/jdk.internal.loader.NativeLibraries.loadLibrary(NativeLibraries.java:174) at java.base/jdk.internal.loader.NativeLibraries.findFromPaths(NativeLibraries.java:315) at java.base/jdk.internal.loader.NativeLibraries.loadLibrary(NativeLibraries.java:287) at java.base/java.lang.ClassLoader.loadLibrary(ClassLoader.java:2422) at java.base/java.lang.Runtime.loadLibrary0(Runtime.java:818) at java.base/java.lang.System.loadLibrary(System.java:1989) at org.opencv.osgi.OpenCVNativeLoader.init(OpenCVNativeLoader.java:17) at org.dcm4che3.opencv.StreamSegment.(StreamSegment.java:76) at org.dcm4che3.opencv.NativeImageReader.getNativeImage(NativeImageReader.java:260) at org.dcm4che3.opencv.NativeImageReader.read(NativeImageReader.java:251) at org.dcm4che3.imageio.codec.Decompressor.decompressFrame(Decompressor.java:299) at org.dcm4che3.imageio.codec.Decompressor.writeFrameTo(Decompressor.java:285) at org.dcm4che3.imageio.codec.Decompressor.writeTo(Decompressor.java:269) at org.dcm4che3.imageio.codec.Decompressor$1.writeTo(Decompressor.java:202) at org.dcm4che3.io.DicomOutputStream.writeAttribute(DicomOutputStream.java:213) at org.dcm4che3.io.DicomOutputStream.writeAttribute(DicomOutputStream.java:189) at org.dcm4che3.data.Attributes.writeTo(Attributes.java:3123) at org.dcm4che3.data.Attributes.writeTo(Attributes.java:3062) at org.dcm4che3.io.DicomOutputStream.writeDataset(DicomOutputStream.java:150) at org.dcm4che3.net.DataWriterAdapter.writeTo(DataWriterAdapter.java:67) at org.dcm4che3.net.PDUEncoder.writeDIMSE(PDUEncoder.java:475) at org.dcm4che3.net.Association.invoke(Association.java:1286) at org.dcm4che3.net.Association.invoke(Association.java:1274) at org.dcm4che3.net.Association.cstore(Association.java:939) at org.dcm4che3.tool.storescu.StoreSCU.send(StoreSCU.java:511) at org.dcm4che3.tool.storescu.StoreSCU.sendFiles(StoreSCU.java:415) at org.dcm4che3.tool.storescu.StoreSCU.main(StoreSCU.java:294)

This causes the store process to stop and fail.

To Reproduce We're not sure what causes this and how to reproduce this behavior.

Desktop (please complete the following information):

• OS: Windows 10 Pro
• Java Version: 17.0.5

Additional context The storescu process works for some studies but fails for others. We've had this issue intermittently occur on certain other machines as well starting as far back as May 18th 2023.

[jssuttles]

We are still investigating this issue, but we're not as familiar with Java and OpenCV and a direction would certainly be helpful.

[nroduit]

Do you mean the command line storescu or with the Java API?

[jssuttles]

@nroduit Command line StoreSCU

[nroduit]

Did you modify the bat file? because I do not understand why you get "\<file path>\opencv_java.dll"

Or do you change the environment variable %DCM4CHE_HOME% or %JAVA_OPTS%

To debug, add "echo %JAVA_OPTS%" before the last command line of the bat file to show the command option.

[jssuttles]

Thanks for guidance. We do change the bat file. I'll take a look at this soon.

We haven't upgraded to the latest version yet. We use slf4j-simple instead of logback. We use a packaged version of Java. I'll return with the java opts echo.

[jssuttles]

To clarify: \<filepath> is me replacing my computer's file path with \<filepath>. That's not how it shows up in the error. (I just don't want my computer's file path available on the internet.)

[jssuttles]

(I hope you don't mind if I ping you @nroduit.)

[nroduit]

Please check with the original file first, as we cannot respond to issues that contain modifications.

[jssuttles]

Ok. I don't think I'll be able to do that where the issue occurs, but I'll see what I can do.
