I'm trying to use MessagePack in a WAR application in Glassfish, but I'm getting this exception (although JavaAssist already is a library of the project):
java.lang.NoClassDefFoundError: javassist/ClassPath at
org.msgpack.template.builder.BuilderSelectorRegistry.initForJava(BuilderSelectorRegistry.java:58)
at
org.msgpack.template.builder.BuilderSelectorRegistry.(BuilderSelectorRegistry.java:38)
at
org.msgpack.template.TemplateRegistry.(TemplateRegistry.java:38)
at org.msgpack.MessagePack.register(MessagePack.java:149)
this happern When I call
org.msgpack.MessagePack.register()
Any ideas?
I posted the error in the MessagePack's JIRA and this is the answer:
I added this libraries to my classpath:
javassist.jar msgpack-0.5.2-devel.jar slf4j-api-1.6.2.jar
slf4j-ext-1.6.2.jar slf4j-simple-1.6.2.jar
Copying them directly to the lib folder of glassfish, to: C:\Program
Files\glassfish-3.1\glassfish\domains\domain1\lib
I'm gonna work now in adding them as part of my war
Thank you very much again.

I am facing the following issue whenever I try to implement the .aar file instead of the direct lib module dependency.
Caused by: org.gradle.api.internal.artifacts.ivyservice.DefaultLenientConfiguration$ArtifactResolveException: Could not resolve all files for configuration ':app:debugCompileClasspath'.
Caused by: org.gradle.internal.resolve.ModuleVersionNotFoundException: Could not find :xxxlib-release:.
N:B: I have configured the library project for jitpack also with the publishing config. A few days back, there was no issue but now I am getting errors for both the .aar and jitpack versions of my library which I guess is related. Additionally, I have upgraded to Android Studio Bumblebee and using targetSdkVersion 29 or 30; kotlin = 1.6.0 and classpath 'com.android.tools.build:gradle:7.0.3'
I can't find out what am I missing here. Any help will be appriciated, thanks.
When I try to use c3p0 to test a mysql database connection, Eclipse shows the following error:
caused by:java.lang.NoClassDefFoundError:com/mchange/v2/ser/indirector,
I googled and was unable to find an answer.
Could anyone help me? I am a java rookie, thanks!
First, make sure that your project is properly loading mchange-commons-java, where the stuff you are com.mchange.v2.ser.* lives. It is a transitive dependency of c3p0.
Hopefully you are using c3p0-0.9.5. Try changing the c3p0 config param contextClassLoaderSource to library to avoid some ClassLoader confusions.
I think you are only placing c3p0 jar in tomcat lib.
If you copy mchange-commons-java jar also than this issue will be resolved.
I have the same problem. And I am using IntelliJ IDEA. Perhaps you can fix it by follow steps:
Add c3p0 and mchange-commons-java to your 'libs' folder and add them
as 'Library';
Open 'File->Project Structure->Project
Settings->Artifacts', then find c3p0-* and mchange-commons-java in
the 'Available Elements', and 'Extract Into Output Root'.
Then
build artifacts again.
In my case I was missing mchange-commons-java-0.2.11 (use your version) jar that contained the com/mchange/v2/ser/indirector class. We need this and c3p0-0.9.5.2 jars to be kept in app/WEB-INF/lib directory.
Just adding that worked!!!
I have small gear with tomcat cartridge. When I try to execute war that that generate images with Java3D I get following exception:
Caused by: java.lang.ClassNotFoundException: javax.media.j3d.Node
As a first think I tried to add Java3D at classpath, I have added to my pom.xml:
<dependency>
<groupId>java3d</groupId>
<artifactId>j3d-core-utils</artifactId>
<version>1.3.1</version>
<scope>compile</scope>
</dependency>
This added to final war following artifacts:
[INFO] +- java3d:j3d-core-utils:jar:1.3.1:compile
[INFO] | +- java3d:vecmath:jar:1.3.1:compile
[INFO] | \- java3d:j3d-core:jar:1.3.1:compile
When I deployd adjusted war following exception raised:
Caused by: java.lang.UnsatisfiedLinkError: no J3D in java.library.path
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1886)
As far as I understand exception, it says that there are no native Java3D libraries at java.library.path. So I installed Java3D from suggested link, I also updated j3dcore.jar, j3dutils.jar and vecmath.jar. Also catalina.sh was updated:
export LD_LIBRARY_PATH=/var/lib/openshift/<my-application-id>/app-root/data/j3d-1_5_2-linux-amd64/lib/amd64
I suppose that there is no X11 server to work with, because of that Java3D have to run in headless mode. It could be set in catalina.sh like this:
JAVA_OPTS=${JAVA_OPTS}" -Djava.awt.headless=true"
Now it seems that all java3D classes and *.so libraries are found. Now there is another problem:
java.awt.HeadlessException
at sun.java2d.HeadlessGraphicsEnvironment.getDefaultScreenDevice(HeadlessGraphicsEnvironment.java:64)
Problem is that Java3D class Canvas3D can't work in headless mode. Only way could be to connect to some X11 server with screen. It could be done with export DISPLAY=:0.0
As far as I was able to test, it seems that there is no X11 server, providing screen to which could Java3D connect. Because of that it's not possible to run Java3D at OpenShift platform with tomcat cartridge.
Thanks for your help.
Have you tried adding it to your pom.xml to get installed via maven? Or add the .jar file to your project manually... http://mvnrepository.com/artifact/java3d/j3d-core-utils/1.3.1
You might require more than just the core package.
Since you are deploying a war file, and not using maven, i think you would need to download the jar files and embed them in your war file as libraries and use them.
You might also check out this article: https://www.openshift.com/kb/kb-e1087-how-to-include-libraries-jar-files-in-your-java-application-without-using-maven
It looks like there is also a .so file that you would need to include with something like -Djava.library.path
Here is the file with the jars & .so file on java.net http://download.java.net/media/java3d/builds/release/1.5.2/j3d-1_5_2-linux-amd64.zip
Speaking with the dev ops team, it does not seem that package is installed on the servers.
I've upgraded my grails application from 1.3.9 to 2.2.3 and then to 2.3.3. I read the release and upgrade notes for 1.3.9->2.2.3 and then from 2.2.3->2.3.3
I am using OpenJDK 6, Jetty 6 and the plugin jetty 1.1, MySQL 5.5 and I have the connector library under lib
Now my issue is if I run grails clean and then grails run-app the application runs without any problems but if I stop it and run grails run-app again I get a gigantic error (see here: http://pastebin.com/36MpXhir)
I also found that changing something like adding a space somewhere in BuildConfig.groovy (anything that makes it be recompiled) makes the application run normally.
Looking at the stacktrace the first thing that puzzles me is
[02.12.13 16:13:59.919] [main] pool.ConnectionPool Unable to create initial connections of pool.

There are references to org.apache.tomcat even though I'm using jetty (and removed tomcat from BuildConfig.groovy).
Did anyone else encounter such a problem?
Don't put jar files in the lib directory if they're available in a public Maven repo. It's far better to download jars once and keep them in a local cache, and reuse them as needed.
The MySQL driver is used as the commented-out example in the generated BuildConfig.groovy - just un-comment it :) You might want to bump up the version to the latest, e.g.
dependencies {
runtime 'mysql:mysql-connector-java:5.1.27'
}
This is a good site for finding Maven artifacts: http://mvnrepository.com/artifact/mysql/mysql-connector-java
If you do have a jar that's not in a Maven repo (e.g. one with shared code at your company) then you can put it in the lib directory, but it's not auto-discovered. Run grails compile --refresh-dependencies to get it added to the classpath.
For me same error has occurred while running the Grails Application.Then I debug and view the code history of my code which was committed recently.
From that I found the issue that was:
Inside the controller file I send the instance with-out properly
Eg:
**def list=[personInstance.]---> error occurred.**
**render list as JSON**
Then I correct my mistake-->clean the app --> run the app
Now its working fine.
I am currently working on integrating Java application General Architecture For Text Engineering (GATE) with a Rails application using JRuby architecture. When we worked on integrating JRuby with log4j, I am getting following error:
0 [main] DEBUG Main.class - Hello world
gate/Gate.java:80:in `<clinit>': java.lang.NoClassDefFoundError: org/apache/log4
j/Logger (NativeException)
from gateapp/Main.java:86:in `main'
from test.rb:12
test.rb is the name of ruby program.
I tried importing all the log4j apache libraries, and included the class file in the test.rb file.
When I run the Java program alone its running fine. But when I generate the jar file and include them in Ruby file (test.rb) , I am getting this error
java.lang.NoClassDefFoundError: org/apache/log4j/Logger (NativeException) problem is occuring. How to deal with this problem ?
You need to make sure the log4j JAR file is in your classpath. One way to do this is to set the CLASSPATH variable in your environment. Another way would be to call require in your ruby code like
require "/some/path/MyStuff.jar"
Here is my config to set it up with couchbase Java SDK
include Java
def setup_log4j
java::lang.System.setProperty("net.spy.log.LoggerImpl", "net.spy.memcached.compat.log.Log4JLogger")
fa = Java::OrgApacheLog4j::FileAppender.new();
fa.setName("FileLogger");
fa.setFile("./log/#{Rails.env}.log");
fa.setLayout(Java::OrgApacheLog4j::PatternLayout.new("%d %-5p [%c{1}] %m%n"));
fa.setThreshold(Java::OrgApacheLog4j::Level::INFO);
fa.setAppend(true);
fa.activateOptions();
Java::OrgApacheLog4j::Logger.getRootLogger().addAppender(fa)
end
Just beware that I required the lo4j.jar file earlier.
Worth to mention that there is project named log4jruby.
