Exception in thread "main" java.lang.NoClassDefFoundError: javax/activation/DataSource

[robgwheeler]

I get the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: javax/activation/DataSource

when attempting to run:

java -jar node_modules/jsonix-schema-compiler/lib/jsonix-schema-compiler-full.jar -d mappings -p PO purchaseorder.xsd

on the CLI

I'm trying to get the examples working before I try real data. Any help would be greatly appreciated.

This should be part of JRE. Which Java version do you use?

[robgwheeler]

I updated to java version "9"
Java(TM) SE Runtime Environment (build 9+181)
Java HotSpot(TM) 64-Bit Server VM (build 9+181, mixed mode)

and i'm now getting the following error:

Java 8 should work.

With Java 9 it's probably the new module system which does not load javax.activation. I don't have Java 9 experience yet so not sure how to fix this.

[henkesn]

I just ran into the same issue. From java 9 on, jaxb (and some other JEE modules are not provided on the default classpath anymore. --add-modules java.xml.bind should do the trick.

java --add-modules java.xml.bind -jar node_modules/jsonix/lib/jsonix-schema-compiler-full.jar -d mappings -p PO purchaseorder.xsd

[ghdna]

I tried adding --add-modules java.xml.bind like @henkesn directed but now I'm hit with this:

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by com.sun.xml.bind.v2.runtime.reflect.opt.Injector (file:/Users/ghdna/jsonix-schema-compiler-full-2.3.9.jar) to method java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int)

P.S. The conversion still went through.

I tried running an Arabic tokenizer/diacritizer and got the same error message:

Exception in thread "main" java.lang.NoClassDefFoundError: javax/activation/DataSource

....

Caused by: java.lang.ClassNotFoundException: javax.activation.DataSource

I have limited experience in Java. As instructed by the developer, I entered the following line via the terminal:
java -Xmx2500m -Xms2500m -XX:NewRatio=3 -jar MADAMIRA-release-20170403-2.1.jar -rawinput samples/raw/SampleTextInput.txt -rawoutdir . -rawconfig samples/sampleConfigFile.xml

Can anyone let what could be the cause of this error and how to fix it?

[henkesn]

@fhr21 try to add --add-modules java.xml.bind as first argument.

[fhr21]

The developer wrote this command to run the program thru the terminal in mac computer:
java -Xmx2500m -Xms2500m -XX:NewRatio=3 -jar MADAMIRA-release-20170403-2.1.jar -rawinput samples/raw/inputdata.txt -rawoutdir samples/rawoutputdata.txt -rawconfig samples/sampleConfigFile.xml
I tried running the program replacing the first argument with with the line you gave me as follows:

java --add-modules java.xml.bind -jar MADAMIRA-release-20170403-2.1.jar -rawinput samples/raw/inputdata.txt -rawoutdir samples/rawoutputdata.txt -rawconfig samples/sampleConfigFile.xml

This is what I get:

Error occurred during initialization of boot layer java.lang.module.FindException: Module java.xml.bind not found

As of https://stackoverflow.com/questions/52502189/java-11-package-javax-xml-bind-does-not-exist, it was removed in Java11. Adding following lines to Maven's pom.xml helped me:

I was having this problem with Java 8, spring boot and camel, this solution worked for me.

[dipak-ksolves]

I am having the same issue and also tried the --add-modules java.xml.bind but getting this:
Error occurred during initialization of boot layer
java.lang.module.FindException: Module java.xml.bind not found

And I am using jdk 11.0.8

[poebrand]

As noted in the following post, java.xml.bind has been removed from Java 11+.
https://stackoverflow.com/a/52502208

However, with a side-by-side installation of a lower version (Java 10 in my case), I was able to make the following command work in Windows via powershell:
."C:\Program Files\Java\jdk-10.0.2\bin\java.exe" --add-modules java.xml.bind -jar ".\jsonix-schema-compiler-full-2.3.9.jar" -generateJsonSchema .\schemas\order.xsd
