Hi,
I would like to use OWB on WebSphere 6.1 (similar to Tomcat 5.5) which
requires Java 1.5 and supports Servlet API 2.4.
OWB needs Java 1.6 and Servlet API 2.5.
Part 1: Java 1.6
After a close look into the sources I see, there is one basic dependency
to Java 1.6: java.util.ServiceLoader
To solve this problem, I've added a utility class in my local copy and
delegate calls to ServiceLoader to this utility.
The utility class itself calls ServiceLoader, if the class is available
(Java 1.6) or uses com.googlecode.bspi.ServiceLoader (Java 1.5).
So the application needs one new dependency (only in the case of Java 1.5).
I've also changed the maven-compiler-plugin to generate Java 1.5
compatible byte code.
Jira: https://issues.apache.org/jira/browse/OWB-582
Part 2: Servet API 2.5
Some classes uses the new function ServletContext.getContextPath() for
logging and giving a thread a useful name.
Here, I also added a utility class, and call
servletContext.getServletContextName() in the case of Servlet API 2.4
Jira: https://issues.apache.org/jira/browse/OWB-583
Conclusion:
There are not many dependencies to the new APIs and there are simple
workarounds. With this changes (and a similar patch for the
ServiceLoader in CODI) I'm able to run OWB on WebSpere 6.1 and Tomcat
5.5 with Java 1.5.
Any suggestions?
Regards,
Udo
