I am getting a error when deploying spring-saml application in Wildfly 8 with IBM JDK 1.7. Interestingly Googling got me no answers.
The error stacktrace is

Any ideas?
I think the problem is the dependency between opensaml.jar and serializer.jar.
As you used Spring Security SAML plugin, you may be using the following libraries (as they are in the demo application):
opensaml-2.6.1.jar
spring-security-config-3.1.2.jar
spring-security-core-3.2.1.jar
spring-security-web-3.2.1.jar
spring-security-saml2-core-1.0.2.jar
Wildfly 8 (and 9 too) both are packed with serializer-2.7.1.jbossorg-1.jar (/modules/system/layers/base/org/apache/xalan/main) which seems to have some differences with the "standard" serializer-2.7.1.jar (https://mvnrepository.com/artifact/xalan/serializer/2.7.1).
I compared both jars and they contain the same classes and resources, however their sizes differ. The "standard" one was compiled with IBM JDK 1.3.1, JBoss version with Oracle JDK 1.6_20 - This is based on both MANIFEST.MF files.
Note opensaml.jar was compiled with the "standard" serializer library based on the Maven repository information.
I was searching for the source code of the "standard" serializer-2.7.1.jar but I could not find it. However, I found another 2.7.1 build, this time from Spring and compared with the one JBoss source, and they have some differences. I assume that if I compare the "standard" source code I will find the same. It is not a simple file renaming as I have seen before.
The next thing I did was a little bit of experimentation.
Firstly just dropped serializer-2.7.1.jar into my application.war/WEB-INF/lib, started Wildfly (v 8.2.1) and the application started without any issues. Removed the JAR and back to the exception.
Next, I changed WF’s xalan module to use serializer-2.7.1.jar instead serializer-2.7.1.jbossorg-1.jar (removed the jar file and edited module.xml). Started WF, and surprise, I got the same exception. I even tried changing to serializer-2.7.1.jbossorg-2.jar (packed with Wildfly 10) and serializer-2.7.2.jar (https://mvnrepository.com/artifact/xalan/serializer/2.7.2) and the exception still occurred.
Finally, I rolled back the module changes to the original state and created a custom WF module including serializer-2.7.1.jar and added the module dependency in the application “jboss-deployment-structure.xml”.
It is important to highlight the application starts without any issue (or additional serializer.jar) under WAS 8.5.5 and WAS Liberty Profile 8.5.5. (target production AS and another development AS respectively). Custom modules in Wildfly are handy to avoid modifying the application WAR on this kind of scenarios.
As an additional note, as part of my test to solve this issue I upgraded to the latest Spring-Security (3.2.9) and Open-SAML (2.6.4) and I needed to upgrade to serialize.jar to 2.7.2.
P.S. I worked with Mahe in the same project, but he left few months ago and I got the task to work out this issue.

I have a web application that used to run fine on many web servers (tomcat, jboss, weblogic and websphere). Now, however, it has an error when deploying on WebSphere 9.
The app contains the jar javax.transaction-api-1.2. Some of its classes, e.g., javax.transaction.xa.XAResource, are also included in Java SE, but not all of them. Some are specific to Java EE and are required by some 3rd-party libraries in my app. The app is always deploying with child-first (parent-last) classloader.
WebSphere 9 throws this error during startup when the app tries to load the Oracle JDBC driver:
java.lang.LinkageError: loading constraint violation: loader "com/ibm/ws/classloader/CompoundClassLoader#7157be44" previously initiated loading for a different type with name
"javax/transaction/xa/XAResource" defined by loader "com/ibm/oti/vm/BootstrapClassLoader#422c7b1b"
Note that we aren't actually using XA transactions in the app, we are using regular transactions.
On other servers, and previous versions of WebSphere, it was never a problem. The server didn't care that we load XAResource from inside the war, even if it was previously loaded somewhere in the server. Now WebSphere 9 is different, it says that the app classloader already loaded this class from the server, but I don't know why or when did this happen.
Any idea how to solve this?
Remove the transaction API from your application. JTA 1.2 is already included in the server and provides no value in your applications. It's always risky to bring Java EE/SE APIs in a parent-last class loader unless you are 100% certain that they are technically necessary, because they can lead to issues like this one.
I can't say how this worked in previous server versions (there have been some Java-level changes in enforcing linkage issues like this), but the solution is reasonably straightforward.
At the end we did two things to solve this problem.
1) We upgraded the jta jar to version 1.3 (link here). This jar solves the problem by avoiding duplicate classes - it contains only J2EE classes and omits the J2SE classes that are already included in the JVM.
2) We upgraded WebSphere server from 9.0.0.7 to 9.0.0.11.
At the time, I suspected just upgrading the jar should suffice, but our QA had some issues with it and they also upgraded the server. Due to lack of time, we didn't investigate it further and just decided to do both.
In my project I am forced to use these packages:
com.sparkjava:spark-core:2.3, which ends up using jetty-server:9.3.2.v20150730
org.apache.spark:spark-core_2.10:1.2.0, which ends up using jetty-server:8.1.14.v20131031
Note that com.sparkjava and org.apache.spark have nothing to do with each other. They are called both spark funnily.
The issue here is that both jetty versions are incompatible, so if I force jetty 8.X the system crashes, if I force jetty 9.X the system crashes again, I get java.lang.NoClassDefFoundError: org/eclipse/jetty/server/ServerConnector in one case and java.lang.NoClassDefFoundError: org/eclipse/jetty/server/bio/SocketConnector in the other.
What I am expected to do in such a situation ?
Note: I've tried to shadow jetty, but the dependency manager resolves just one (9.X by default, or 8.X if I force it) and then it shadows it, so it's really not helping.
It would be exceedingly difficult to resolve this situation.
Jetty 8.1 is about 4 major version behind Jetty 9.3, which represents many hundreds of releases of difference.
Note: Jetty versioning is [servlet_support].[major_ver].[minor_ver].
Jetty 8.x is Servlet 3.0, while Jetty 9.x is Servlet 3.1
The architecture of the connectors has evolved tremendously in that time frame, from being old school blocking Sockets in Jetty 8 to no blocking connectors at all in Jetty 9, with Jetty 9 needing to evolve the connectors to support features in TLS/1.2, and ALPN in order to properly support HTTP/2, and the internal I/O handling to support the new Servlet 3.1 Async I/O feature set.
Solution #1:
You won't be able to have both versions running in the same VM without some sort of classloader isolation, and careful configuration to ensure they don't claim the same resources (listening ports, temp files, etc)
Solution #2:
Upgrade (or downgrade) one or the other spark dependency till you hit a common jetty version. (Spark_2.11 / 2.0.0 seems to support Jetty 9.2.x)
Solution #3:
Apache Spark is open source, go submit a patch that upgrades its use of Jetty to 9.3 (this might be difficult as Apache Spark isn't ready to use Java 8 yet, which is a requirement for Jetty 9.3)
I am trying to run my spring boot application (via Run As -> Spring Boot Application) in a tomcat8 container on STS and I am receiving these errors:

I have searched around for this quite a bit and have found little to guide me in figuring out what the problem is. After going through the spring boot code in the debugger I see that the object named "instance" referenced in the TomcatWebSocketContainerCustomizer.addListener() uses reflection to retrieve a handle to it. This object is associated with the tomcat 7.0.53 jar ($HOME/.m2/repository/org/apache/tomcat/tomcat-catalina/7.0.53/tomcat-catalina-7.0.53.jar). I do not see this in any of my maven dependencies and have tried several techniques to force it to tomcat 8.0.20, nothing seems to work.
After banging my head for a while I started looking at the run configuration for the project in STS (via Run As -> Run Configurations). I found that the Source tab shows tomcat 7.0.53 above version 8.0.20 along with several dependencies that aren't referenced in maven. I am at a loss on where these values come from and not sure how to edit it. For some reason when I try to manually delete these legacy jar files STS doesn't allow me to delete any of them.
Does anyone have an idea of where these dependencies may be coming from and how I can remove them?
They do reference my $HOME/.m2/path/to/tomcat-catalina/<version> dir, so I could simply remove them from my .m2 and theoretically it may work but I'd rather not do this if I don't have to.
I am using spring boot 1.2.x and all of them have this problem.
thanks.
I've got two ideas that you might try.
1) It is possible, that this may be manifestation of this bug in STS 3.6.4: https://issuetracker.springsource.com/browse/STS-4085
The depencies you aren't expecting to see may be coming from the maven 'test' scope. (The bug explicitly mentions 'srt/test' but the same happens with jar dependencies). You can verify whether this bug is the cause by using the regular "Run As Java Application" on your main class.
If that works, then it is almost certainly this bug. If it also fails with a similar error then its something else... then try:
2) You must be getting the unwanted tomcat version from somewhere, probably indirectly as dependency of something else.
Try using the m2e 'dependency hierarchy' to find where it came from like so:
open pom.xml
Click the 'Dependency Hierarchy' tab.
Type 'tomcat' in the 'Filter' box.
I finally figured it out.
In my $WORKSPACE/.metadata/.plugins/org.eclipse.m2e.core/workspacestate.properties it lists all poms, jars and wars from my workspace build with the maven plugin. I noticed that a pom in the file points to the exact version tomcat that is being loaded in my spring boot project. Once I deleted these projects from my STS I can successfully launch the spring boot app :-)
When I re-import the maven projects back to STS the error occurs again, then disappears when I remove them.
These projects have no connection to the project that I am trying to launch. Therefore I think the bug is in m2e.
I'll file a bug and update this post when it is complete.
thanks #Kris for working through it with me.
Im building an application based on Spring Boot v1.2. While my application boots successfully and executes well (so far.. ), I'm unable to test using the spring boot framework because of an AbstractMethodError.
The last few lines of the trace are as below

To analyze the above error, I checked the jar files from classpath involving the above classes. So the info is available as below
jar:file:/C:/rearch/intellij-workspace/springbootproj/lib/spring-aop-4.1.2.RELEASE.jar!/org/springframework/aop/framework/ProxyFactory.class
jar:file:/C:/rearch/mavenrepo/org/springframework/data/spring-data-commons/1.9.1.RELEASE/spring-data-commons-1.9.1.RELEASE.jar!/org/springframework/data/repository/core/RepositoryInformation.class

jar:file:/C:/rearch/intellij-workspace/springbootproj/lib/spring-test-4.1.2.RELEASE.jar!/org/springframework/test/context/support/DependencyInjectionTestExecutionListener.class
I'm not exactly sure on why spring-data-commons is coming up from maven repostory folder, while the others are being served from the project library.
While I debug that, I meanwhile need your help in figuring out the version compatibility between the above libraries.
I wasnt able to exactly pin point on what exactly is causing the error. Please help!
Thanks
The issue was with the intellij configuration of libraries which conflicts with Spring boot application. I manually replaced the required libraries from Maven repository and that worked out for me.
Per request from Elron..
Open the project folder in explorer and verify if the third party library versions in your project matches the ones you actually expect it to be. If something doesnt match, just replace the file with the one you expect it to be. In my case, since I use Maven, I didnt see a need for explicitly saving those libraries in a new lib folder under the project. So, I just deleted all of the files inside the lib folder and things started working again.
For fix this error, change the spring-data-jpa version to 1.5.0.RELEASE
I have faced this issue .
Get rid of spring-data-commons and change spring-data-jpa version to 1.9.0.RELEASE.

I am currently working on a portlet that is using the commons-collections jar file and am getting a NoSuchMethodError. To resolve this issue I need to change the classloader of my WAR file from PARENT_FIRST to PARENT_LAST (in the application.xml file).
However, when I do this my portlet will not launch and when I log into the console it displays the message "The portlet is temporarily disabled". If I change the classloader back to PARENT_FIRST then it will launch again but then I get the NoSuchMethodError.
Does anybody have any suggestions on how to fix this issue ?
I am not sure how, but today I started getting error messages in the logs when I was getting "The portlet is temporarily disabled". I was getting a java.lang.LinkageError which was down to the fact that I had the servlet-api-2.5.jar and a jaxb jar which was conflicting with webshpere j2ee.jar. Once I removed these dependencies and set the classloader to PARENT_LAST, it seems to work properly. It seems that a lot of people face similar issues. The link below is also useful http://forum.springsource.org/showthread.php?33663-dispatcher-servlet-quot-not-a-servlet-class-quot-in-websphere
#MTH,
please try adding commons-collections as a shared library. See here for an example on how others have used shared library support [1]. That will give you the steps, just do it for the jars that you need to override/replace from WAS's classloader

thanks,

You haven't provided any logs... but still, one of the most important things to look out for when setting your application to run PARENT_LAST is that your application isn't bundled with any system-level classes that may conflict with the ones provided by WebSphere Portal. For example, classes that pertain to the Portlet specification or the JavaEE specification.
