I've got into a scenario where I have to get an Axis2 based ws consumer working within WebMethods as a java service. I've implemented the ws consumer first in netbeans just to see if it works and thus i found that the minimal amount of jars I'll require are the following:
[ xmlschema-1.4.7.jar, apache-mime4j-core-0.7.2.jar,
axiom-api-1.2.13.jar, axiom-impl-1.2.13.jar, axis2-adb-1.6.2.jar,
axis2-kernel-1.6.2.jar, axis2-transport-http-1.6.2.jar,
axis2-transport-local-1.6.2.jar, commons-codec-1.3.jar,
commons-httpclient-3.1.jar, commons-logging-1.1.1.jar,
httpcore-4.0.jar, mail-1.4.jar, neethi-3.0.2.jar, wsdl4j-1.6.2.jar ]
I've uploaded these jar files under the IS/packages/{package_name}/code/jars folder. Whenever I try to execute the java service that would send the request and process the response I get the following exception:
java.lang.reflect.InvocationTargetException:
org.apache.axiom.om.OMFactory.getMetaFactory()Lorg/apache/axiom/om/OMMetaFactory;
From the IS error log file I found that the actual error message is as follows:
org.apache.axiom.om.OMFactory.getMetaFactory()Lorg/apache/axiom/om/OMMetaFactory;
Caused by: java.lang.reflect.InvocationTargetException: null Caused
by:
java.lang.NoSuchMethodError:org.apache.axiom.om.OMFactory.getMetaFactory()Lorg/apache/axiom/om/OMMetaFactory;
The platform is WebMethods 8.2 under Linux environment. The JDK version is 1.6.0_32 and the application server under WebMethods is Jetty.
Actually the solve of this problem was a bit more tricky. First of all I manually had to configure the manifest file of the package on the IS server to use the jars provided in the package abnd thus it wouldn't get in conflict with the Axis used by the IS itself. On the other hand I had to manually add the ClassLoader because WebMethods can't use META-INF based information from jar files as it seems. To solve this problem simply use:
System.setProperty("org.apache.axiom.om.OMMetaFactory", "org.apache.axiom.om.impl.llom.factory.OMLinkedListMetaFactory");
That solves all the problems.

I am trying to run a spark job on a Hadoop cluster that also makes an http request to another server. I am using org.apache.httpcomponents to make this request, which works fine locally on my machine. However this fails the moment I submit the job to the cluster (managed by Cloudera) with the following error:
User class threw exception: java.lang.NoSuchFieldError: INSTANCE
at org.apache.http.conn.ssl.SSLConnectionSocketFactory.(SSLConnectionSocketFactory.java:151)
at org.apache.http.impl.client.HttpClientBuilder.build(HttpClientBuilder.java:977)
at org.apache.http.impl.client.HttpClients.createDefault(HttpClients.java:56)
From all the reading I have done, this error is caused by multiple versions of Apache Http client jar. It appears that Hadoop/Spark engine has it's own dependency to Apache Http client and that is a different version than the one I am using. Because my jar is run as part of the hadoop/spark engine it ends up including both my version of http as well as the one Hadoop requires.
If I add 'compileOnly' for org.apache.httpcomponents in my build.gradle and submit, I get this error instead:
User class threw exception: java.lang.NoClassDefFoundError: org/apache/http/impl/client/HttpClients
Is there a way for me to configure this in gradle so that when I build my jar, it will use the already existing version on Hadoop? ie. A way to declare a temporary dependency (when running locally download and use latest version, but when building UberJar drop the dependency)?
UPDATE
I decided to try swapping to a different http library (okhttp3) to see if that would resolve the issue. However I get a very similar exception when trying to run through the cluster here too:
User class threw exception: java.lang.NoSuchFieldError: Companion
at okhttp3.internal.Util.(Util.kt:70)
at okhttp3.OkHttpClient.(OkHttpClient.kt:959)
Looks like Cloudera also supplies a version of okhttp with it's spark2 client which is unfortunate.
Can you please help me with following error I'm facing in WAS9 environment:
In order to resolve the import

The server where your WAS9 has been deployed has different version of the above jar file. You need to have same version of jar files both in your eclipse where you have developed your codes and the server where you are deploying the war or ear.
mavan dependency file pom.xml is used during your project compilation. It might add the jar in your binary under lib folder as well. But WAS9 might considering the one which is in server's CLASSPATH. Hence check your class path and replace that jar with the one which you have mentioned in your pom.xml file. Hope that will fix your issue.
We can eliminate this exception by adding webProfile-7.0 in our server.xml, but how ever this is not working with javaee-7.0 not sure, if one knows about how to handle this in javaee-7.0 please share your approach.
Our web service client in live environment recently got the exception:
java.lang.NoClassDefFoundError: Could not initialize class com.sun.xml.internal.ws.fault.SOAPFaultBuilder
at com.sun.xml.internal.ws.client.sei.SyncMethodHandler.invoke(SyncMethodHandler.java:107)

I've done a lot of search online, including a few posts here at StackOverflow:
Catching webservice exception with CXF: NoClassDefFoundError: SOAPFaultBuilder
Could not initialize class com.sun.xml.internal.ws.fault.SOAPFaultBuilder
java.lang.NoClassDefFoundError: Could not initialize class com.sun.xml.internal.ws.fault.SOAPFaultBuilder
And my understanding was our client received a SOAP Fault from the server and it's missing some jar file. So I'm trying to solve the problem by first recreating it.
I created a simple Web Service server project in Eclipse which has a web method throws a simple fault class annotated by #WebFault. Then I created a simple Web Service client project which consumes the web method. The client project doesn't have any additional libraries/jars in its classpath; all it has is the JRE. To my surprise, it didn't throw the NoClassDefFoundError exception! Instead, I got the javax.xml.ws.soap.SOAPFaultException I defined on the server side.
The class SOAPFaultBuilder is indeed in rt.jar in JRE. So the simple web service projects I created probably just work as they should. However, how come the web service client in our live environment throw the NoClassDefFoundError exception? That project definitely has rt.jar in the classpath.
Can anyone please shed some light on this problem? If it's missing some jar files (either from the jaxws RI or Apache CXF or others), why would the super simple client I created didn't throw the error? Both the live environment and my local environment use Java7u51.
I have encountered the same problem and I could subsequently resolve this.
Due to the following error mentioned in the Problem, the underlying cause of the SOAP Fault could not be found.
I followed the steps mentioned in the following link, to identify the reason for NoClassDefFoundError.
http://javarevisited.blogspot.in/2011/06/noclassdeffounderror-exception-in.html
I could find the following errors in my application log:
java.lang.ExceptionInInitializerError
Caused by: java.lang.ClassCastException: com.sun.xml.bind.v2.runtime.JAXBContextImpl cannot be cast to com.sun.xml.internal.bind.api.JAXBRIContext
The reason for the above classcast exception is due to conflicting jar files.
rt.jar (this is present in jre classpath)
jaxb-impl-2.0.1.jar (this is present in my application classpath).
I have removed the file jaxb-impl-2.0.1.jar from my classpath and the actual error is gone.
I had the same erorr and I resolved this issue by deleting the jax-impl.jar from the tomcat lib folder. It was a possible conflict of the jaxb jar versions with one of my webapps installed in tomcat.

I am trying to run the Spring 4 example given # https://spring.io/guides/gs/messaging-stomp-websocket. When I try to connect to socket, it throws me following exception. As per the example you need tomcat 7.0.50 and I checked the executable jar which has right version of tomcat. Any pointer would be helpful.
java.lang.IllegalArgumentException: No 'javax.websocket.server.ServerContainer' ServletContext attribute. Are you running in a Servlet container that supports JSR-356?
Check that you have tomcat7-websocket.jar and websocket-api.jar bundled in your executable jar - perhaps you're just getting vanilla tomcat without the extra websocket bits.
I got the same error message in another use case: I deactivated auto configuration and added WebSocketConfig manually to the configuration. Then I got the abovementioned error message.
Fixing the problem was easy: just adding WebSocketAutoConfiguration to the configuration.
I know that this is an ancient thread but I ran into this error and resolved it in modern times by adding implementation("org.springframework.boot:spring-boot-starter-tomcat") explicitly to my project.
I am trying to add metrics library to existing webservice on WAS 7. I am getting below error
Error 404: javax.servlet.UnavailableException: SRVE0203E: Servlet [AdminServlet]: com.yammer.metrics.reporting.AdminServlet was found, but is missing another required class. SRVE0206E: This error typically implies that the servlet was originally compiled with classes which cannot be located by the server. SRVE0187E: Check your class path to ensure that all classes required by the servlet are present.SRVE0210I: This problem can be debugged by recompiling the servlet using only the classes in the application's runtime class path SRVE0234I
What are the other run-time dependencies required for metrics-servlet-2.2.0?
I have metrics-core-2.2.0.jar and metrics-servlet-2.2.0.jar in my WEB-INF\lib folder.
Threads, ping and healthcheck servlets work fine.
I think your missing some more required jars, are you not using maven or gradle for dependency management
Please refer here to know all required jars that metrics-servlet-2.2.0.jar depends on. http://mvnrepository.com/artifact/com.yammer.metrics/metrics-servlets/3.0.0-BETA1
My suggestion is, it is always difficult to maintain dependencies without Maven/Gradle or any other build tools :).
