I am using Stanford NLP library for an IBM Bluemix app. I have added both stanford-corenlp-3.5.1-models.jar and stanford-corenlp-3.5.1.jar to build path. And consequently, the app is running fine in the local webshpere liberty server.
When I build the WAR file through ant build of build.xml, I ensure that both the files are included. I can also see them present inside the WAR file. But when I deploy the WAR file on Bluemix, and run it, I get the following error:
ERR java.lang.NoClassDefFoundError: edu/stanford/nlp/pipeline/StanfordCoreNLP
What might be the problem?
I have ensured that the jar file is in the war file:
Please ensure that the jar files are present in the WEB-INF\lib folder in the WAR file.
I have faced the same issue and by making the jar available in WEB-INF\lib folder it was resolved.

I'm trying to extract .jar of my project through the artifact build in intellij but the extracted jar file is not opening. I'm using the jcommon .jar file which is external library and I also added this jar file to my project build.
Java is not a problem. I tried another project without any external libraries and it works well.
I also tried to edit the manifest file and add the classpath for the external libraries but same.
How to extract jar file with external libraries or jar file?
The error message is showing
Java application launch failed. Check Console for possible error messages related to 'Users/jaehunshim Desktop/CS/CS_IA/out/artifacts/ CS_IA_ iar2/Cs_IA jar'
I have a project which run in tomcat.
I have this error from tomcat.
java.lang.ClassNotFoundException: net.glxn.qrgen.javaase.QRCode.
I know that this error occur because I did not import my JAR file when I was building the WAR file but then I do not have the source code anymore which mean I cannot build a WAR file again.
Just wanna to know is there a way for me to put my JAR file into tomcat so the related function will call the JAR?
Thanks.
You should be able to copy the jar straight into $CATALINA_HOME/lib and it should work.
I've added mysql connector jar file, but class not found exception still arises.
*
Your error clearly says that the MySql connector jar is not placed in the correct folder. The correct folder is WEB-INF/lib. So place your jar in this folder.
You have your eclipse project referencing the mysql library. This allows the compiler, in eclipse, to find the classes when compiling. However, you do not have the library as part of your web app when you publish it to your tomcat server. You need to remove the library from the project, and copy the jar file into your app's WEB-INF/lib directory.
java.lang.classnotfoundexception com.mysql.jdbc.MySql issued by WebAppClassLoader. This tells that you need to include MySql connector jar in your web path under WEB-INF/lib directory.
I'm developing a web application in JBoss in Eclipse Luna using external jars. I have imported the jars clicking on Project => Properties => Build Path => Add External Jars. Because the web application will need to use those jars, i have placed them in the MyApp.war/WEB-INF/lib folder, so, when the webapp will be finished, i'm sure i can just export the .war folder and deploy it on another server.
1) The problem is that everytime i turn on my pc in the morning, the deployment process gives me a ClassNotFoundException. I see that the external jars are no longer in their place. As far as i know, i'm not using any plugin to manage dependencies (i'm a newbie on webapps)
EDIT:
2) what i do is unpack my zip containing the jars again in the lib folder. Strangely, if i unpack them in a subfolder (for example, i place the jars in lib/httpcomponents/lib) JBoss cannot find the jars. What's the reason?
Try to inserting the external jar files in to jboss server lib directory (jboss\server\default\lib)
My project is using some jars which are dependent on the external jar httpclient-4.2.3.
In eclipse my project is running smoothly.
But when I am creating a Jar of my project it is showing error.
I found the error that it is picking httpclient from mahout jars which is an older version.
I know we can control classpath ordering of external jars through order and export in eclipse but it is not working properly.
Can someone tell me how I can force eclipse to prioritize some jars over another when I am creating jar of my projectc.
