I am trying to move legacy application (ear application) from Websphere to liberty.
However on startup I am getting lot of "ClassNotFound" errors like

BaseServletFil is defined in abc.jar which is not bundled inside the ear
To resolve the error, I added following configuration to server.xml
<application id="ABC_EJBEAR" location="abcuiejb.ear" name="ABC_EJBEAR">
<classloader>
<privateLibrary>
<fileset dir="${server.config.dir}/myLibrary" includes="*.jar" scanInterval="5s" />
</privateLibrary>
</classloader>
</application>
myLibrary directory is created at wlp\usr\servers\server1\myLibrary and contains abc.jar.
Any pointers in resolving this error will be helpful. Also how to troubleshoot classloading issues (for third party jars like apache commons)

I have a spring boot application that works fine on Tomcat 8. When I try to deploy it on Websphere 8.5.5 with "Class loader order" set to "Classes loaded with local class loader first (parent last)" the application fails to start with the following exception:

Just adding my experience with this problem, looking around on the various answers to similar problems I found out that the problem could be caused by some javax-servlet related jar in the classpath. After some trial and error I noticed that the spring-boot-starter-web dependency has an inherited spring-boot-starter-tomcat dependency. Excludung this jar from the application classpath when deploying on Websphere 8.5.5 solved the problem.
I am trying to deploy an ear file in JBoss.
My project structure is jar>war>ear.
In the war file I have webapp>WEB-INF>jboss-deployment-structure.xml where I have mentioned
<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
<deployment>
<exclusions>
<module name="org.apache.commons.logging" />
</exclusions>
</deployment>
</jboss-deployment-structure>
when I deploy the war file in the JBOSS, it deploys it fine.
But when I try to deploy the ear file having the war file inside.
It is giving the following error:

I used to get the same error when deploying the war file, which was fixed by the xml file. But now while deploying the ear file I am getting the same error. Any pointers will help
I am getting below error in Eclipse console when i try to start the web sphere LP server (WP 7).

I have added the required datasource in my server.xml
**<library id="DB2JCCLib">
<fileset dir="${server.config.dir}/resources/DB2" includes="db2jcc.jar, db2jcc_license_cisuz.jar, db2jcc_license_cu.jar"/>
</library>
dataSource id="db2" jndiName="jdbc/db2">
<jdbcDriver libraryRef="DB2JCCLib">
</jdbcDriver>
<properties.db2.jcc databaseName="DB2" serverName="tsoc.nnnn.com" portNumber="5002"/>
</dataSource>**
DB2 Jars are in the give location.
Am i missing something or any pointer how to debug this ??
Thanks
If using a dataSource in server configuration, Liberty would try to load data source implementation classes such as
com.ibm.db2.jcc.DB2DataSource
com.ibm.db2.jcc.DB2ConnectionPoolDataSource
com.ibm.db2.jcc.DB2XADataSource
rather than the driver class that shows in the exception,
com.ibm.db2.jcc.DB2Driver
so a good guess (lacking the exception stack) is that your application may be trying to use DriverManager.getConnection instead of using the configured dataSource. If you really want to do this (you will be losing out on many capabilities provided by the application server such as global transaction enlistment and connection pooling) then you would need to make the JDBC driver libraries directly available to your application.
For example,
<application location=...>
<classloader commonLibraryRef="DB2JCCLib"/>
</application>
I am migrating my java web application from Jboss 7.1.1 Final to Wildfly 10,using :
spring 4.2.0,
hibernate 5.0.7,
jpa 2.1

You need to delete the hibernate.cfg.xml and move the configuration from this file to persistence.xml.
Then You have also to remove all hibernate files from WEB-INF/lib folder, because WildFly has its own ones and this situation also possibly made a conflict.
More details on this problem in this link : JBoss Community Forum
I also had a similar issue with Wildfly 10.0.0.Final. In my project also we have all hibernate related libraries within the project's lib directory. But the jboss provided libraries caused conflicts so i have removed the content within the tag <module xmlns="urn:jboss:module:1.3" name="org.hibernate"> in module.xml file available in JBOSS_HOME\modules\system\layers\base\org\hibernate\main directory. Also i have removed the dependencies of hibernate libraries in jboss-deployment-struture.xml as,
<exclusions>
<module name="org.hibernate" slot="main"/>
</exclusions>
After these changes i can able overcome the conflict issues related to hibernate.Hope this will help.
Please note jboss-deployment-struture.xml change alone has not resolved my issue the change mentioned on module.xml file is mandatory.
We were using Memcached for session management in our web application with Tomcat 7 and it worked liked charm. In order for it work, I added following jars to Tomcat's lib folder
spymemcached-2.8.12.jar
couchbase-client-1.1.4.jar
memcached-session-manager-tc7-1.6.5.jar
memcached-session-manager-1.6.5.jar
And made following change to Tomcat's server.xml
<Context path="customersupport" docBase="customerSupportOrderCentral#v2" sessionCookieName="CUSTOMERSUPPORT-JSESSIONID">
<WatchedResource>WEB-INF/web.xml</WatchedResource>
<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
memcachedNodes="n1:oc-cs-elasticcache.w8eptf.cfg.usw1.cache.amazonaws.com:11211"
sticky="false" requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$" />
</Context>
Now we are in process of upgrading our JDK to 1.8 and Tomcat version to 8. I have been researching online for it and it turned out since tomcat 8 doesn't support getSessionCookieName, I have to update memcache jar files for tomcat 8. so I added new set of jar files at tomcat's lib folder as below.
spymemcached-2.11.1.jar
memcached-session-manager-tc8-1.8.1.jar
memcached-session-manager-1.8.1.jar
couchbase-client-1.4.0.jar
And Kept server.xml same but now Tomcat is throwing following error while starting up.

If I dont change server.xml to include memcache manager, its working fine but with memcache session manager its throwing above error. I can really use some help here to resolve this issue.
Thanks
I had the same issue and got stuck for 2 days. The issue on my end was I had the below memcache specific jars in tomcat/lib and in another project specific classpath - tomcat/{project}/conf. The issue got resolved when I removed these jars from tomcat/{project}/conf
spymemcached-2.11.1.jar
memcached-session-manager-tc8-1.8.1.jar
memcached-session-manager-1.8.1.jar
