Websphere Error SRVE0206E SRVE0187E SRVE0234I SRVE0266E

I'm currently wasting my time trying to figure out why WAS won't load my EAR and why said EAR have problem.
Context:
One of my colleague updated a version of a jar and then my m2e seem to have not picked up and was giving thousand of error (was working fine before)
I tried to check if it was Nexus (work fine). My encrypted password in the setting.xml (work fine).
I decided to try maven from the command line, everything worked fine there to.
When I tried again in RAD (IBM eclipse) everything was now ok, no more error.
I then proceeded to put the generated EAR in my websphere server via add and remove project and I get multiple error when I try to start the server with that ear. (see below)
I though that because it was compiled via maven cmd prompt, I might have compiled with the wrong jvm or something so I deleted my maven repo (.m2 in the user) and try to get the jar via m2e in RAD only.
It's worked until I started the server with the new EAR and got the same set of error.
Any idea on what to do to get rid of these error and have a healthy server.
Here some of the error:

Solr Deployment on Websphere 8.5.5 as WAR application

I am installing solr on WAS 8.5.5 with IBM jdk 7.
I deployed the solr as a war and added solr.data.dir and solr.solr.home to custom properties.
Upon accessing the url: http://localhost:9080/solr,
I see the below error on the browser:
Error 500: javax.servlet.ServletException: Filter [SolrRequestFilter]: org.apache.solr.servlet.SolrDispatchFilter was found, but is missing another required class
And the following error in the logs:
SRVE0293E: [Servlet Error]-[com.ibm.ws.webcontainer.extension.DefaultExtensionProcessor]: java.lang.NoClassDefFoundError: org.apache.solr.servlet.SolrDispatchFilter (initialization failure) at java.lang.J9VMInternals.initialize(J9VMInternals.java:176) at java.lang.J9VMInternals.newInstanceImpl(Native Method) at java.lang.Class.newInstance(Class.java:1600) at java.beans.Beans.instantiate(Beans.java:241) at java.beans.Beans.instantiate(Beans.java:89) at com.ibm.ws.webcontainer.filter.WebAppFilterManager._loadFilter(WebAppFilterManager.java:533) at com.ibm.ws.webcontainer.filter.WebAppFilterManager.loadFilter(WebAppFilterManager.java:475) at com.ibm.ws.webcontainer.filter.WebAppFilterManager.getFilterInstanceWrapper(WebAppFilterManager.java:308) at com.ibm.ws.webcontainer.filter.WebAppFilterManager.getFilterChain(WebAppFilterManager.java:380) at com.ibm.ws.webcontainer.filter.WebAppFilterManager.doFilter(WebAppFilterManager.java:892) at com.ibm.ws.webcontainer.filter.WebAppFilterManager.invokeFilters(WebAppFilterManager.java:1025).....
The lib folder of WEB-INF do contain the solr dependencies
Any Help from anybody ?

After scratching my head for 48 hours, finally able to make SOLR up and running on WebSphere.
Looks like the whole fundamental is to understand the class loading strategy on WAS8, and hence choosing the right strategy.
Have enumerated the different steps for solr deployment on WAS 8

Error deploying a mybatis-truts application

We have a Java application that we deploy using .war files on tomcat server. The war is copied on the webapp directory (tomcat stopped) and then we start the server. We have several scripts that automate the process and we have deploying on development-backup and production servers without problems until two days ago... Then we were able to deploy on development machines, but in backup and production (ovh machines) we received an exception starting tomcat:
### Error building SqlSession.
### Cause: org.apache.ibatis.builder.BuilderException: Error creating document instance. Cause: java.io.IOException: Stream closed
org.apache.ibatis.exceptions.PersistenceException:
### Error building SqlSession.
### Cause: org.apache.ibatis.builder.BuilderException: Error creating document instance. Cause: java.io.IOException: Stream closed

at org.apache.ibatis.session.SqlSessionFactoryBuilder.build(SqlSessionFactoryBuilder.java:51)
at org.apache.ibatis.session.SqlSessionFactoryBuilder.build(SqlSessionFactoryBuilder.java:39)
Redeploying old .war works fine, but new .war produces all the time this exception. We have spend lot of hours trying to figure out what is wrong, but the same .war that does not work on production work on a development machine and (this is incredible) if we deploy using another name for the war (just renaming the .war file) the application works.. But we need the application to work using this specific context name.
Please... help!

Finaly solved...
The main reason was the checking url from haproxy that in this version uses database, so, while the context are deploying haproxy try to load this url and causes several initializations on mybatis...
Changing the url haproxy query solves the problem, but I'm not sure the good way to avoid the initialization problem under load.

java.lang.NoSuchMethodError: org.apache.commons.fileupload.servlet.ServletFileUpload.parseRequest

I am handling file uploads by a multipart filter as described here. I created a WAR file and deployed on Weblogic 10.3.3 server and got error:
<Dec 8, 2011 5:37:07 PM IST> <Error> <HTTP> <BEA-101020> <[ServletContext#26087289[app:playground module:playground.war path:/playground spec-version:null]] Servlet failed with Exception

Then I deployed same WAR file on Tomcat 7.0.11 server and it is successfully running. How is this caused and how can I deploy successfully on Weblogic?

Deployment on Weblogic 10.3.3 results in an error:
java.lang.NoSuchMethodError: org.apache.commons.fileupload.servlet.ServletFileUpload.parseRequest(Lorg/apache/commons/fileupload/RequestContext;)Ljava/util/List;
Deployment on Tomcat 7.0.11 is successful.
Weblogic already ships with Apache Commons FileUpload libraries. This error indicates that they are of an older version than which you have in /WEB-INF/lib.
You have at least 3 options:
Remove the JARs from /WEB-INF/lib.
Replace them by exactly the same version as Weblogic is using.
Change the Weblogic classloading policy to load classes from application first.

You can use following API to upload files to JBoss Server
http://commons.apache.org/fileupload/index.html

Check If your Jar Library has duplicate Jar files with Different versions.
Delete the old version file.

WevDav example project in Apache Wink throws unsupported encoding exception

I am trying to compile and run WebDav example project supplied as part of examples of Apache Wink project. I have successfully deployed the project into JBoss and can reach it throw http. However, when i try to use Total Commander with WebDav plug in, i get the following exception:
15:13:41,595 ERROR [[restSdkService]] Servlet.service() for servlet restSdkService threw exception
java.io.UnsupportedEncodingException: "utf-8"
at java.lang.StringCoding.decode(StringCoding.java:170)
at java.lang.String.(String.java:443)
at java.lang.String.(String.java:515)
etc...
Using windows WebDav network folders, produces no results at all. Jboss server version 5.1.0 GA.
Does anybody succeeded in running this example using WebDav client?

I believe that the encoding name should be uppercase; i.e. "UTF-8".
