I am trying to implement push notification for my app. i had set up the project in eclipse added google-play-services.jar in the java buildpath and checked it in order and export.so my app was working absolutely fine when i was doing registration with gcm and was getting the registration id from gcm too.but when i try to build my app from command line i am getting the below error
java.lang.NoClassDefFoundError: com.google.android.gms.gcm.GoogleCloudMessaging
i added the google-play-services.jar in the classpath so the code compiled without any issue but at runtime i am getting the above exception.looks like its not able to find the jar at runtime. how can i make the jar available at runtime also please help.
Go to configure build path -> order and export and select(check box) the packages(jars).
No matter what the build path contains in eclipse, it has nothing to do with an application. All the jars have to be added to the classpath.
I would use the following command to start the application after build:
java -cp google.jar;jarA.jar;jarB.jar;jarC.jar -jar application.jar
After the -cp option fill in the semicolon separated list of jars that you use.

ErrorOccuredDuringInitializationofbootlayer I keep getting this error when I run
my test:
Error occurred during initialization of boot layer
java.lang.module.FindException: Unable to derive module descriptor for
C:\Users\Bonfire.eclipse\org.eclipse.platform_4.12.0_867647348_win32_win32_x86_64\plugins\com.beust.jcommander_1.72.0.jar
Caused by: java.lang.IllegalArgumentException:
com.beust.jcommander.1.72.0: Invalid module name: '1' is not a Java
identifier
How can I fix it?
Add TestNG Library to classpath in buildpath ( not to module path). It will work fine.
To avoid this error, do not add TestNG library in the project or src folder. Try adding it into the package. To do so , follow the below mentioned procedure.
Right click on the package, click Build Path->Configure Build Path, go to Libraries tab, select Classpath and click on Add Library to select TestNG.

As per the discussion Launch with java 11 fails: Error: Could not find or load main class with Caused by: java.lang.ClassNotFoundException: with there are some issues with some particular classpaths for java-11 and the launch fails if:

Where as java-8 works fine.

Outro
Eclipse plugin: TestNG testcase does not run with Jdk11
Need to add 1.8 version library
Remove TestNG from build path library and add again
Recheck - the issue should be resolved.
I got same issue and I solved it. When creating the project, don't create module-info.java. When the project was already created with the module-info.java, deleting this file didn't help me.
I just created new project without module-info.java, and all works good now.
Best option to resolve this:
Find all file and folder starting with . e.g. — .metadata / .setting and delete them.
Add all the JARS.
Add testNG Libraries.
Execute it.
Done.
I am trying to build my app, but I have the next error.

I am trying to use jetty-nosql-memcached as jetty session backend.
jetty-nosql-memcached: https://github.com/yyuu/jetty-nosql-memcached
After I compiled the jar and put the file "jetty-nosql-memcached-0.4.1-SNAPSHOT-jar-with-dependencies.jar" into the following folder,
$JETTY_HOME/lib or
$JETTY_HOME/lib/ext or
$JETTY_BASE/lib or
$JETTY_BASE/lib/ext
Then I try to start up jetty, all the above setup throws the following exception:
ClassNotFoundException: org.eclipse.jetty.nosql.memcached.MemcachedSessionIdManager
I tried with an param after starts.jar
e.g. java -jar start.jar jetty.home=$JETTY_HOME
it successfully loads the class, however, it does not read the $JETTY_BASE war file anymore. ($JETTY_HOME and $JETTY_BASE rested in different directories)
May I know what is the correct why to include an external library for Jetty?
Many thanks!
Add More information
Jetty version
9.1.0.v20131115
I figured out two ways to include external libraries
Add --lib=$EXTERNAL_LIB_LOCATION in the command line.
java -jar start.jar --lib=$EXTERNAL_LIB_LOCATION
Put the library in $JETTY_HOME\lib\ext, and start jetty in $JETTY_HOME
cd $JETTY_HOME
java -jar start.jar
I am receiving an NoClassDefFoundError in Eclipse when I try to run my project.
My Project looks like this:
JavaProject: BulkAdmin
- src
- com.mycompany.bulkadmin.SDK.util
- Login.java
Dynamic Web Project: JSPTesting
- src
- com.mycompany.bulkadmin.jspController
- Controller.java
- WebContent
- index.html
- execute.jsp
This is the control flow:
index.html loads
index.html has a form that redirects to execute.jsp
execute.jsp takes the info returned in the form and makes a static call to Login.java
execute.jsp prints the results of the call
Controller.java uses Login.java. I was receiving compilation errors. To resolve them I did this:
Right click on JSPTesting -> properties
Choose java build path on the left bar
Choose projects tab
Click add
Choose BulkAdmin (Project)
I am not sure why but now when I am getting a NoClassDefFoundError. I have done some googling. I think that this means that I have messed up my classpath somehow but I am not sure how to resolve this.

I am using tomcat (in Eclipse) as my server
The exception shows up in the browser and the eclipse console
execute.jsp is a JSP
It seems like there are many similar questions to this on SO. I have read about 15 of them and tried various things however I think that my question has a different solution. I can provide more information.
Rightclick your dynamic web project, go to Properties > Deployment Assembly and add the dependent projects there. This way they will end up as JAR in /WEB-INF/lib, exactly there where you want it to be.
In Eclipse versions older than 3.5 you need to go to Properties > Java EE Module Dependencies.

The NoClassDefFoundError indicates that a class that was available during compilation is no longer available at runtime. Your problem is that the com/myCompany/bulkadmin/cSDK/util/Login class is available in the compilation classpath (in Eclipse via the Project reference you added to the build path) but not in the runtime classpath (Tomcat, which has no idea how to find this class).
You need to add the BulkAdmin project to the web-app class path when deployed on Tomcat as well.
One way to do this would be to export the BulkAdmin project as a JAR and put it into the WEB-INF/lib directory of your JSPTesting project.
I just added "-Djava.library.path=" to the "VM Arguments" under Run Configuration in Eclipse and everything works fine until I tried to add an external JAR file. I get the following error:
java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path thrown while loading gnu.io.RXTXCommDriver
Exception in thread "main" java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path
Am I not setting something properly in Eclipse?
If your interested I forked RXTXserial a while back since thier update "schedule" sucks. I have just ported it over to the Android platform too. We decided to move the native libs into the jar and use reflection to deploy them. The API is the same as RXTX, but everything just works. You can find jars and full project sources at:
http://code.google.com/p/nrjavaserial/
The exception indicates that the class gnu.io.RXTXCommDriver tries to load a native library, which would be named rxtxSerial.dll on Windows and rxtxSerial.so on Linux, and the JVM cannot find it in the directories listed in java.library.path. Have you tried to add a JAR containing the library to java.library.path? I don't think that's possible, it has to be a directory containing the extracted library file.
Appearently that external library has a dependancy with another class gnu.io.RXTXCommDriver
. Perhaps you will need to add that library to class path.
