Some problem with examples in chapter2 #4

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
When I was using the paint-modular example in chapter2,after typing in 
"ant"and"java -jar launcher.jar"

What is the expected output? What do you see instead?

Error starting framework: org.osgi.framework.BundleException: Unresolved constra
int in bundle org.foo.shape.circle [1]: Unable to resolve 1.0: missing requireme
nt [1.0] package; (package=javax.swing)

Do you have any OSGi related properties in your environment? The javax.swing 
package should be exported from the system bundle - this is typically 
controlled by the org.osgi.framework.system.packages property, when this is not 
set then the default system bundle exports should include javax.swing.

However, if you have the org.osgi.framework.system.packages property set then 
its value will replace the default list of exported packages from the system 
bundle, which could be why it's not finding javax.swing. Note to append rather 
than replace use the org.osgi.framework.system.packages.extra property.

Hi !
Exactly the same problem !!
I've just reduce the jdk version : jdk7 -> jdk6
It's ok now...

I also have the same problem. I don't have OSGi related properties in my 
environment. 

How can I fix this problem?

#c4 ... are you using JDK7? can you try JDK6?

Original comment by mccu...@gmail.com on 15 Nov 2012 at 9:38

GoogleCodeExporter commented 9 years ago 
yes, and I can't reduce it to jdk6 due to another project.

When we created the samples the Felix launcher (contained in the lib directory) 
did not contain a profile for JDK7 (see 
https://issues.apache.org/jira/browse/FELIX-2864) which is why this error 
occurs. I'll look into updating the launcher or updating the default.properties 
embedded in the launcher (which contain the profiles).

As a workaround you can use "java -Djava.specification.version=1.6 -jar 
launcher.jar bundles" to force it to use the Java6 system packages profile even 
when running JDK7.

Sweet! The workaround works! Thank you :-)

Will use it until you post the update.

Fixed in http://code.google.com/p/osgi-in-action/source/detail?r=37 - you'll 
need to rebuild the launcher (and either copy it to the example or rebuild the 
example chapter code)
