Jean-Sebastien Delfino commented on TUSCANY-2182:
-------------------------------------------------
Here are the steps to get webapps that use the node2 launcher (see
tutorial/catalog-webapp for an example) working on WebSphere using a WebSphere
shared library for the Tuscany JARs.
1. Copy the following JARs from the Tuscany distribution lib directory to the
WebSphere lib/ext directory:
jaxb2-reflection-2.1.4.jar
jaxb-api-2.1.jar
jaxb-impl-2.1.6.jar
jaxb-xjc-2.1.4.jar
stax-api-1.0-2.jar
xercesImpl-2.8.1.jar
2. Create a WebSphere shared library for Tuscany containing the following JARs
from the Tuscany distribution lib and modules directories.
NOTE this is a SUBSET of the JARs in the Tuscany distribution, carefully
selected to avoid conflicts with the JARs from WebSphere and the JDK that it
uses:

4. After deploying the Web app change it's classloading settings to "Classes
loaded with application class loader first" and "Single class loader for
application".
5. Add to the Web app a reference to the Tuscany shared library.
> ClassLoader issues with node2 launcher on WebSphere
> ---------------------------------------------------
>
> Key: TUSCANY-2182
> URL: https://issues.apache.org/jira/browse/TUSCANY-2182
> Project: Tuscany
> Issue Type: Bug
> Components: Java SCA Core Runtime
> Affects Versions: Java-SCA-1.2
> Reporter: Jean-Sebastien Delfino
> Assignee: Jean-Sebastien Delfino
> Fix For: Java-SCA-1.2
>
>
> The classloader used by Node2 uses a parent-first loading scheme which does
> not work on WebSphere application server, as different versions of the
> Tuscany runtime dependencies are on the classpath of Webapps in the WebSphere
> environment.
> The fix for that issue is simply to ensure that the Node2 launcher uses a
> parent-last classloading scheme to load its runtime classes.
