After upgrading to Java 11 my PDF generation stop working (using Apache FOP) with the following error.
Caused by: jakarta.xml.bind.JAXBException: ClassCastException: attempting to cast
jar:file:jakarta.xml.bind-api-3.0.0.jar!/jakarta/xml/bind/JAXBContext.class to
jar:file:jakarta.xml.bind-api-3.0.0.jar!/jakarta/xml/bind/JAXBContext.class.
Please make sure that you are specifying the proper ClassLoader.
Which make no sense at all since it's the same file. Previous problems solved migrating to jakarta but this remains.
Adding the following dependency solves de issue
<dependency>
<groupId>org.glassfish.jaxb</groupId>
<artifactId>jaxb-runtime</artifactId>
<version>3.0.0</version>
</dependency>
Recently i started to learn DeepLearning4j library , so i cloned a dl4j project and executed in eclipse.
After executing , it showed following error:
Intel MKL FATAL ERROR: Cannot load mkl_intel_thread.dll.
I checked my windows path variables and i could not find any variable of name MKL.
Following are the dependency that i used in the pom.xml :
<dependency>
<groupId>org.nd4j</groupId>
<artifactId>nd4j-native-platform</artifactId>
<version>0.8.0</version>
</dependency>
<dependency>
<groupId>org.deeplearning4j</groupId>
<artifactId>deeplearning4j-core</artifactId>
<version>0.8.0</version>
</dependency>
You're using a version of dl4j that's more than a year old. Please update to something we support and try again. Our website does not even mention this version. Please use the quickstart docs for the latest version: https://deeplearning4j.org/docs/latest/deeplearning4j-quickstart
Thanks!
since i migrate to jdk9 i'm getting the following error at runtime:
java.lang.NoClassDefFoundError: javax/xml/ws/Service
I'm not getting compilation error but only runtime error.
the module-info is the following:
module CXFPExGenCaller {
requires java.xml;
requires java.logging;
requires java.xml.bind;
requires java.xml.ws;
exports ......;
}
and the pom.xml contains the following dependencies:
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.2.12-b141001.1542</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-core</artifactId>
<version>2.2.11</version>
<scope>test</scope>
</dependency>
even if i tried different configurations the final result is still this annoying error!
Does someone has an idea of what is going on here?
I've understood the mistake I was doing, trying the following answer:

I'm using JUnit to test my class on IntelliJ IDE and I was setting only compiler option instead of setting also runtime's VM Options as per the following image:
I'm not sure it's the best practice but this solves my current problem
I'm trying to use iText Java.
When you run the example "how to sign" the following error occurs:
Caused by: java.lang.ClassNotFoundException: org.bouncycastle.tsp.TimeStampTokenInfo
According "Getting Started with iText - How to sign a PDF using iText", I have to use the BouncyCastle.
I downloaded the file: bcprov-jdk15on-147.jar from BouncyCastle download page.
And added to the project: Java Build Path/Libraries/Add External JARs...
I added the following line:
Security.addProvider(new BouncyCastleProvider());
When you run the example the same error occurs.
So I downloaded another file: bcpkix-jdk15on-147.jar entitled "PKIX/CMS/EAC/PKCS/OCSP/TSP/OPENSSL"
And added to the project: Java Build Path/Libraries/Add External JARs...
Now I have two Jars.
When you run the example the following error occurs:
Caused by: java.lang.ClassNotFoundException: org.bouncycastle.asn1.DEREncodable
I tried downloading the file "bcprov-ext-jdk15on-147.jar" but did not solve the problem.
I am using iText 5.2.1 and eclipse on Windows 7 64 bits.
iText marks bouncycastle dependencies as optional. If you require them, you need to add the dependencies in your own pom file.
To find out which dependency to include in your project, open the itextpdf pom.xml file of the version you are using (for example 5.3.2, here) and search for the 2 bouncycastle dependencies.
<dependency>
<groupId>org.bouncycastle</groupId>
<artifactId>bcprov-jdk15on</artifactId>
<version>1.47</version>
<optional>true</optional>
</dependency>
<dependency>
<groupId>org.bouncycastle</groupId>
<artifactId>bcmail-jdk15on</artifactId>
<version>1.47</version>
<optional>true</optional>
</dependency>
Copy them into your pom file and remove the optional option.
<dependency>
<groupId>com.itextpdf</groupId>
<artifactId>itextpdf</artifactId>
<version>5.3.2</version>
</dependency>
<dependency>
<groupId>org.bouncycastle</groupId>
<artifactId>bcprov-jdk15on</artifactId>
<version>1.47</version>
</dependency>
<dependency>
<groupId>org.bouncycastle</groupId>
<artifactId>bcmail-jdk15on</artifactId>
<version>1.47</version>
</dependency>
BouncyCastle libs are undergoing heavy API changes that broke the compatibility with other libs like iText.
Either
use a previous version of BouncyCastle libs. Old versions can be found here. However, you'll have to find the right version of iText that was compatible with this particular version of BC.
make your own build of iText (the SVN trunk has been fixed). iText can be build with Maven (there's a short readme file at the root of the SVN). Please note that it's at your own risk, there may be bugs in trunk.
wait for the next version of iText. From my experience, iText releases come every couple of months, sometime more often, sometimes less. I'm not an iText committer though, so I can't give you any ETA.
More information can be found in this thread
With itextpdf version 5.5.4 org.bouncycastle dependencies are marked as <optional>true</optional>. This means you MUST include those dependencies in your own pom, or you can run into classnotfound exceptions.
<dependency>
<groupId>com.itextpdf</groupId>
<artifactId>itextpdf</artifactId>
<version>5.5.4</version>
</dependency>
<!-- Bouncycastle dependencies necessary as they are optional = true
in itextpdf ... but they're not-so-optional in reality -->
<dependency>
<groupId>org.bouncycastle</groupId>
<artifactId>bcprov-jdk15on</artifactId>
<version>1.49</version>
</dependency>
<dependency>
<groupId>org.bouncycastle</groupId>
<artifactId>bcpkix-jdk15on</artifactId>
<version>1.49</version>
</dependency>
from version of bcprov-jdk15on-147, class of DEREncodable is no longer exist under the path of org.bouncycastle.asn1. You can use version before 146 (including 146) to resolve this question.
It's strange that the jars available at bouncycastle.org don't seem to contain this class. Perhaps, you may want to use one from the locations listed in this page (link).
i have the same problem, but a fix it when i download the libreria and update those files on /WEBINF/LIB
Luckily, the dependency jars are being delivered along with the iText now.
Please check the repository link below and download extrajars.zip file

For jruby-ers with the same failure, I updated to jruby-complete-9.1.13.0.jar from jruby-complete-1.6.6.jar and the problem seemed to resolve...FWIW...
Java developer here. I am using JAXB to create bind objects. When I attempt to create a JAXBContext like this:
JAXBContext.newInstance("com.mycompany.jaxb.pkg1:com.mycompany.jaxb.pkg2");
I get a NullPointerException:

Googling for the relevant keywords led me to several discussion threads saying that this is a known bug and I should upgrade to version 2.0.3. But here is my maven POM file:
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-impl</artifactId>
<version>2.2.1</version>
</dependency>
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.1</version>
</dependency>
...as you can see, I am already beyond version 2.0.3. (And yes, I tried rolling back to the old version; it didn't help.)
Has anyone seen this for a reason OTHER than version 2.0.2 or older, or does anyone have pointers for how to go about tracking down the problem?
Okay, for the record: I found the solution.
As several threads had suggested, the source of this bug was using a version of JAXB which was older than 2.0.2. My error was that my maven POM file was being overridden by another POM file which was importing an older version of the library.
Thanks to skaffman, and everyone else who took a look.
