The application does not start in websphere 8.5.5, but works fine in tomcat

Question

I have a web application that can be deployed to tomcat, but the same application does not start in websphere 8.5.5. I checked the SystemErr.log file, which gives the following information, I can not debug why the application does not start. If I would like to know more about the problem, what should I do.

Application Server Version: Websphere 8.5.5
Java version: java version "1.7.0_25"
OpenJDK workspace (RHEL-2.3.10.4.el6_4-x86_64)

Here is the web.xml file

Answer 1

The error received says that the /* context is already in use by another application. The contexts for your web applications must be unique.

There is no context-root tag in the web.xml you posted, so WebSphere assumes /* . You can do one of the following:

• Update your web.xml to include the context root . You probably need to redistribute the application for it to take effect.
• Or Change the context root of your application in WebSphere . You can do this by logging in to the console administrator by going to Applications> Corporate Applications> [Application Name]> Context Root for Web Modules. Then the context root can be specified here.

Answer 2

Finally, I can fix the problem.

My application uses the goava guava library, and the library version is 15.0 . I found that the guava library (version: 15.0) is not compatible with jee6 ( more info ). Therefore, I changed the version from 15.0 to 14.0.1, after which the application was deployed correctly.

What I did not understand, how can I understand with the following error message, what went wrong ??? Don't you think it's hard to understand.

Called: com.ibm.ws.webcontainer.exception.WebAppNotLoadedException: Failed to load webapp

I am sure this is useful information.

Answer 3

I was getting the same error, so what I did was registered in the admin console, then sent to the applications, and then to the Websphere corporate application (here you can find a list of all the applications deployed). Just the default Undeploy application (this application is deployed when the web scope is installed). Once it will not work, it will work.

Answer 4

Go to IBM Console-> Application-> Application Types-> Websphere Enterprice Application.

Uninstall all applications except YOUR STATEMENT.

Websphere automatically creates a sample application and in this application some point to "./"
