Import-Package problems
Hey there
I have a question about the Import-Package attribute in the manifest file. For a simple example, I modified the extenderbased.circle such that instead of drawing the circle, I tried to load the png from the file to draw the icon to the frame (in the draw method of Circle). So, using javax.imageio.ImageIO to read the image in, I had to import a non-java.xxx package. So, I placed "Import-Package: javax.imageio.ImageIO" in my manifest file. However, now when the circle bundle is loaded, I get the host of exceptions following the "ClassNotFound" exception for javax.imageio.ImageIO. I have no trouble importing the SimpleShape interface with it's package name as an attribute, but for some reason it's not working with the javax.* packages.
Should be pretty easy to reproduce... I'm using java 1.5SE.
Thanks in advance for any help
Garrett

This error looks pretty normal. The bundle cannot be started because no
one is exporting the javax.imageio package. How are you starting the
example?
If you are manually installing the bundles from your standard Felix
directory (e.g., java -jar bin/felix.jar) then you should be getting
this package exported for you automatically from the class path by the
system bundle. If you look in conf/config.properties, you can see that
Felix sets the default value of org.osgi.framework.system.packages to be
all public packages in the underlying JRE.
If you are starting this using the custom launcher of the extender host
(i.e., starting an embedded instance of Felix), then this example code
is simplified and only exports a few packages from the class path. You
will need to go to the static main() in Activator.java of the extender
host and add "javax.imageio" to the packages it exports.
If this is your scenario, you can simply switch to using "java -jar
bin/felix.jar" in your Felix install directory and manually installing
the bundles and everything should work fine, I would guess.

I was actually trying to use ANT, but I went back and ran the same simulation, but used Maven instead. So, the manifest file (from the jar):

I take it you are not using the Maven build files? If so, you shouldn't
have to add anything to the manifest, because it is generated for you.

You might want to make that
Import-Package: javax.imageio
it needs to be the package not the Class.
