Deeply,
Firstly, "Import-Package" section of cxf-api-2.7.1.jar's MANIFEST.MF
needs to be modified in order to use javax.xml.stream package from
org.apache.servicemix.specs.stax-api-1.0-2.1.0.jar rather than system
package,
[Before modification]
Import-Package: ...,javax.xml.stream;version="[0.0,2)",...
[After modification]
Import-Package: ...,javax.xml.stream;version="[1.0.1,2)",...
Secondly, once finishing the above modification and re-launching felix
4.0.3, another similar error happened:
ERROR: Bundle org.apache.cxf.cxf-api [53] Error starting
file:/E:/gfv4/apachedcxf/distribution/multi-bundle/target/cxf-dosgi-ri-multibundle-distribution-1.4-SNAPSHOT-dir/apache-cxf-dosgi-ri-1.4-SNAPSHOT/dosgi_bundles/cxf-api-2.7.1.jar
(org.osgi.framework.BundleException: Uses constraint violation. Unable
to resolve bundle revision org.apache.cxf.cxf-api [53.0] because it is
exposed to package 'javax.xml.stream' from bundle revisions
org.apache.servicemix.specs.stax-api-1.0 [22.0] and
org.apache.felix.framework [0] via two dependency chains.
Chain 1:
org.apache.cxf.cxf-api [53.0]
import:
(&(osgi.wiring.package=javax.xml.stream)(version>=1.0.1)(!(version>=2.0.0)))
|
export: osgi.wiring.package=javax.xml.stream
org.apache.servicemix.specs.stax-api-1.0 [22.0]
Chain 2:
org.apache.cxf.cxf-api [53.0]
import: (osgi.wiring.package=javax.xml.transform.stax)
|
export: osgi.wiring.package=javax.xml.transform.stax;
uses:=javax.xml.stream
export: osgi.wiring.package=javax.xml.stream
org.apache.felix.framework [0])
For such a problem, I made a *temp* confirmation/fixing: modify
felix.jar/default.properties
(Because I used jre 1.6)
[Before modification]
jre-1.6=, \
...
javax.xml.transform.stax;uses:="javax.xml.stream,javax.xml.transform,javax.xml.stream.events";version="0.0.0.1_006_JavaSE",
\
...
[After modification]
jre-1.6=, \
...
javax.xml.transform.stax;version="0.0.0.1_006_JavaSE", \
...
Then, re-launching felix 4.0.3, anything is OK.
A point to notice is that before felix 4.0.2, in the above
section(jre-xxx), javax.xml.transform.stax does not use "uses" clause.
In addition, I think that we should tell user to add some contents into
conf/config.properties file of the Felix distribution(from 4.0.2)
rather than modifying felix.jar/default.properties because this is an
inner file.
Please confirm what I said above, thanks.
