dbptk-app-2.10.1.jar: javax.xml.bind.JAXBException with Java 15

[ibbenz]

After starting up the dbptk-app the following errors occurred:

Errors: WARN could not get type for name javax.xml.bind.annotation.adapters.XmlAdapter from any class loader Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException Caused by: java.lang.ClassNotFoundException: javax.xml.bind.JAXBException

This issue seems to origin from an incompatibility with Java 15. I use OpenJDK Runtime Environment (build 15.0.2+10) from BellSoft.

According to the following link the jaxb-api jar has to be integrated in the application: https://www.studytonight.com/post/solved-javalangnoclassdeffounderror-javaxxmlbindjaxbexception-in-java-11

Question Will there be soon a release which will tackle this issue? Which would be a feasible workaround where the dbptk-app is able to run with Java 15?

You can add the additional jaxb-api jar into the classpath as you would do to add additional JBDC drivers. https://github.com/keeps/dbptk-developer/wiki/How-to-use-a-JDBC-driver-in-DBPTK-Developer

Thank you, the validation seems to work:

java -cp "C:\KOST\Software_KOST\dbptk_Developer\dbptk-app-2.10.1.jar;C:\KOST\Software_KOST\dbptk_Developer\jaxb-api-2.3.1.jar" com.databasepreservation.Main validate -if C:\KOST\SIARD_TESTS\2022_07_11_SIARD_Test_MySQL\0_Testdatei\0_4-6_oe_Northwind_complex.siard

This error is still present for dbptk-2.10.3.jar luis's fix does not fix.

Try this one:

wget https://repo1.maven.org/maven2/javax/xml/bind/jaxb-api/2.3.1/jaxb-api-2.3.1.jar
java  --add-opens java.xml/com.sun.org.apache.xerces.internal.jaxp=ALL-UNNAMED -cp dbptk-app-2.10.3.jar:jaxb-api-2.3.1.jar com.databasepreservation.Main validate -if test.siard

We will try to improve Java 9+ compatibility in the next release.

That worked! Thank you. On Windows the command line ended up as: java "-Dfile.encoding=UTF-8" --add-opens java.xml/com.sun.org.apache.xerces.internal.jaxp=ALL-UNNAMED -cp "dbptk-app-2.10.3.jar;jaxb-api-2.3.1.jar" com.databasepreservation.Main validate -if TestDB-with-slash.siard
