OK, so I think I have resolved this particular problem by removing the version
information from the
map.put(Constants.FRAMEWORK_SYSTEMPACKAGES_EXTRA,
"com.bt.test;version=1.0.0,javax.servlet,javax.servlet.http;version=2.5");
in my host application to make it:
map.put(Constants.FRAMEWORK_SYSTEMPACKAGES_EXTRA,
"com.bt.test;version=1.0.0,javax.servlet,javax.servlet.http");
Mind you, still can't get my bridge to work, just getting ServiceUnavailable.
Will investigate further.....

Subject: webconsole and servlet api bundle versions
Hello all,
I'm trying to deploy the latest version of webconsole (3.1.8) into my embedded
felix application and I am struggling with the version of servlet api needed.
1. I have tried not supplying any additional bundles and relying on the Serlvet
container (jetty) that has a 2.5 version:
ERROR: Bundle org.apache.felix.webconsole [4] Error starting
file:/home/adrian/work/jetty-6.1.15/bundle/org.apache.felix.webconsole-3.1.8.jar
(org.osgi.framework.BundleException: Activator start error in bundle
org.apache.felix.webconsole [4].)
java.lang.LinkageError: loader constraint violation: loader (instance of
org/apache/felix/framework/ModuleImpl$ModuleClassLoaderJava5) previously
initiated loading for a different type with name "javax/servlet/ServletConfig"
at java.lang.ClassLoader.defineClass1(Native Method)
2. I have tried using com.springsource.javax.servlet-2.5.0.jar. This appears to
load ok, but when I try and access the console from my browser I see:
2011-04-06 17:18:50.114::WARN: Error for /felix/system/console
java.lang.LinkageError: loader constraint violation: when resolving method
"javax.servlet.ServletRequestEvent.<init>(Ljavax/servlet/ServletContext;Ljavax/servlet/ServletRequest;)V"
the class loader (instance of
org/apache/felix/framework/ModuleImpl$ModuleClassLoaderJava5) of the current
class, org/apache/felix/http/base/internal/DispatcherServlet, and the class
loader (instance of
org/apache/felix/framework/ModuleImpl$ModuleClassLoaderJava5) for resolved
class, javax/servlet/ServletRequestEvent, have different Class objects for the
type javax/servlet/ServletContext used in the signature
at
org.apache.felix.http.base.internal.DispatcherServlet.service(DispatcherServlet.java:62)
3. Using com.springsource.javax.servlet-2.4.0.jar gives:
ERROR: Bundle org.apache.felix.webconsole [5] Error starting
file:/home/adrian/work/jetty-6.1.15/bundle/org.apache.felix.webconsole-3.1.8.jar
(org.osgi.framework.BundleException: Activator start error in bundle
org.apache.felix.webconsole [5].)
java.lang.LinkageError: loader constraint violation: loader (instance of
org/apache/felix/framework/ModuleImpl$ModuleClassLoaderJava5) previously
initiated loading for a different type with name "javax/servlet/ServletConfig"
at java.lang.ClassLoader.defineClass1(Native Method)
Any help appreciated.
Thanks
Adrian Smith
