I'm having this exception with some stubs generateds by Axis2:
"The type org.apache.axiom.om.OMElement cannot be resolved. It is
indirectly referenced from required .class files"
I've been reading many posts, and trying to find a solution. What I've found so far is to add the apache tomcat 5.5 library to the build path. It removed the error in the java file, but then, when I to execute any java program inside the project, I got this error:
'Launching myApp' has encountered a problem Exception occurred
executing command line. Cannot run program "C:\Program
Files\Java\jdk1.5.0_22\bin\javaw.exe" (in directory
"D:\Digicel\workspace\Digicel\myClassSample"): CreateProcess error=87,
The parameter is incorrect
then if I remove the apache tomcat library from the build path, I can run the other java programs, but not the one mentioned initially.
Any thoughts about it?
Okay, I've found the cause of the problem with the help of a friend :)
The thing is that Eclipse is aware that one of my dependencies, depends of another library, and Eclipse is checking for it when it tries to build the code.
So, what I've done is try to check which jar file contains this library: " org.apache.axiom.om.OMElement".
I've googled it and found that it is "axiom-api-1.2.10.jar" and finally my file compiled with 0 errors.
He also explained to me that my original solution of adding the apache tomcat server library is adding all the jars that cames with apache tomcat (which is a big list), and probably there may have been a version conflict with my current list of added jars.
So, the fix was to find the appropriate jar and add it to the project.
This error can also occur when a indirect dependency has a corrupt jar file. This may be caused by problems at the public maven repository.
If this is the case removing the local maven repository to download fresh jar files will fix your problem:
rm -Rf ~/.m2/repository/{enter/path/to/broken/stuff}
Goto Maven >Update Maven project>checkmark the Force update >Then Run
..That error Will gone....

Using Eclipse 2018.12, I've installed the Eclipse Kotlin plugin (0.8.20.20200316-1305), created a Kotlin project (using the "New..." options under "Kotlin") and wrote a "Hello World!" program:
Test.kt:
fun main() = System.out.println("Hello World!")
However, when I try to run it I get the message
Error: Could not find or load main class TestKt
Caused by: java.lang.ClassNotFoundException: TestKt
Upon further inspection it seems the class has never been compiled. There is no corresponding .class file anywhere. Under the project directory I see Eclipse configuration directory .settings and files .project and .classpath. Besides that, I have an empty bin directory and a src directory with Test.kt only.
I found two similar questions about this in SO:
In Unable to Run Kotlin Application in Eclipse, the accepted answer simply indicates working with a new version of Eclipse and Kotlin plugin, both older than what I have now. Besides, the problem may have been solved in that case due to a new installation rather than the version.
Kotlin - Error: Could not find or load main class _DefaultPackage is quite old and the accepted answer does not apply anymore. It was about not naming the main class properly, but in my case there is not even a byte code file to be found.
Running "Project -> Compile Kotlin classes" had no effect.
How can I get this simple example to run?
Update: I've updated to 2020-06 (not that it should matter since Eclipse Kotlin lists 2018-12 in its requirements) and replaced Zuly by AdoptOpenJDK HotSpotJDK 11. The error persists. The Eclipse log does not show any related messages.
Update 2: re-created the project in a brand-new workspace but the problem persists.
ErrorOccuredDuringInitializationofbootlayer I keep getting this error when I run
my test:

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.
This error message...

...implies that there was an issue with the java classpath.
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:
The classpath contains a folder with spaces
The classpath length is larger than 32767 characters.
Where as java-8 works fine.

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 attempting to compile EWSJavaAPI1.5 in Eclipse and in IntelliJ. I have had no luck. I keep getting a org.apache.commons.httpclient does not exist error. Its driving me nuts. I added the four required files:
commons-codec-1.4.jar
commons-httpcliient-3.1.jar
commons-logging-1.1.1.jar
jcifs-1.3.15.jar
The four jar files are being referenced, yet it does not find the httpclient when compiling. It may have to do with the class path but I am not sure if I am adding it to the class path correctly. What to do?
Check that the library classpath is set correctly and this library is added to the dependencies of your module. Another possible case could be corrupted jar file, try to download it again.
Trying to use Apache POI in a Eclipse JSP project. The POI jar is in the project's Java Resources Library list.
<%# page import="org.apache.poi.hssf.usermodel.HSSFSheet"%>
at run the following error occurs:
An error occurred at line: 7 in the
generated java file Only a type can be
imported.
org.apache.poi.hssf.usermodel.HSSFWorkbook
resolves to a package
Any ideas? Thanks

The message indicates that the class could not be found on the classpath of your deployed application. Did you make sure that the POI jar is in your WEB-INF/lib folder?
Same happened to me, even when the needed jars were indeed in the WEB-INF folder.
I was using the provided server in SpringSource ToolSuite (STS). It took me several attempts to clean, republish, etc... before it finally worked.
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.
