Java lang noclassdeffounderror javax activation datasource

Issue

I’m trying to send Mail using SMTP on netbean when I get the error message:

run: Exception in thread «main» java.lang.NoClassDefFoundError: javax/activation/DataSource at SendMail.createMessage(SendMail.java:45) at SendMail.main(SendMail.java:59) Caused by: java.lang.ClassNotFoundException: javax.activation.DataSource at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:606) at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:168) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:522) . 2 more C:\Users\Admin\AppData\Local\NetBeans\Cache\12.0\executor-snippets\run.xml:111: The following error occurred while executing this line: C:\Users\Admin\AppData\Local\NetBeans\Cache\12.0\executor-snippets\run.xml:68: Java returned: 1 BUILD FAILED (total time: 0 seconds)

(I use Apache NetBeans IDE 12.0; Java: 15; Java HotSpot(TM) 64-Bit Server VM 15+36-156)

Solution

For classes such as javax.activation.DataSource you need the JAR file for the JavaBeans Activation Framework.

You can download the JAR from Maven Central here — click on the jar link there.

If you are using a dependency management tool such as Maven, Gradle, etc. then use the related configuration (also available in that same page). Using a dependency management tool is strongly recommended over just downloading JAR files one-by-one.

You should also consider replacing your javax imports with jakarta imports, since that is now where these packages are maintained, going forward.

If you do that, then you need to use the Jakarta Activation API, available here. For example:

 jakarta.activation jakarta.activation-api 2.0.1  

And if you do that, you should also replace JavaMail classes too — for example, you can replace this:

import jakarta.mail.Message; 

And use a Jakarta Mail resource, for example:

 com.sun.mail jakarta.mail 2.0.1

I get the following error:

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

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

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

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:

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.

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

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) WARNING: Please consider reporting this to the maintainers of com.sun.xml.bind.v2.runtime.reflect.opt.Injector WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations WARNING: All illegal access operations will be denied in a future release 

P.S. The conversion still went through.

@ghdna thank you so much , that’s was helpfull for me . it work (y)

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
at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:583)
.

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?
