Hello Arthur,
I have added the servicemix version of jasypt
<dependency>
<groupId>org.apache.servicemix.bundles</groupId>
<artifactId>org.apache.servicemix.bundles.jasypt</artifactId>
<version>1.9.2_1</version>
<scope>provided</scope>
</dependency>
and excluded the original jasypt from camel-jasypt dep, so any bundle is using
the above OSGI version.
I defined this in the parent pom with "provided" scope for all modules.
So I assume that all bundles have the servicemix jasypt in their classpath.
I should expect the package "org.jasypt.encryption " in the import section of
the Meta-Inf and in service-import section
"org.jasypt.encryption.StringEncryptor"?

Betreff: Re: Exporting an instance of a 3rd party library as service
The following error message says the importing bundle (order) does not have
access to the class "org.jasypt.encryption.StringEncryptor".
Unable to start blueprint container for bundle order/22.14.0.98-SNAPSHOT due to
unresolved dependencies [(objectClass=org.jasypt.encryption.StringEncryptor)]
In order to use a "reference" with an interface class, the bundle needs to have
that interface class on its own classpath. Is the module with that class in
the list of dependencies for the bundle (the one using "reference)?

Hello Jean-Baptiste, Geoffrey
Here are some more details:
runtime err msg
Unable to start blueprint container for bundle order/22.14.0.98-SNAPSHOT due to
unresolved dependencies [(objectClass=org.jasypt.encryption.StringEncryptor)]
java.util.concurrent.TimeoutException: null
...
this standard exception stacktrace, when a service was not found
I use the maven bundle plugin without import instruction, so it uses * as
default.
The Meta-Inf shows the service/interface listed in the export- and
import-service sections properly. In karaf cmd line with bundle:requirements
and bundle:capabilites both could be seen.
@Geoffry
exactly this I want to achieve, yes.
Base bundle:
...
<bean id="stringEncryptorBean"
class="org.jasypt.encryption.pbe.StandardPBEStringEncryptor">
<property name="config" ref="encryptorConfig" />
</bean>
<service id="StringEncryptor" ref="stringEncryptorBean"
interface="org.jasypt.encryption.StringEncryptor" />
Importing Bundle:
<cm:property-placeholder id="my.xml.placeholder" persistent-id="my.xml.pid"
/>
<enc:property-placeholder encryptor-ref="StringEncryptor" />
One thing I need to add: Running on Windows 10 the pax-jdbc v0.9 is able to
find the service, on WSL2 Ubuntu, Docker jre8-alpine or Mac the service is not
found.
Question: In general, a base bundle should be able to instantiate a class of
another library and offer this as a service?
Does this base bundle should export the packages of this other library? Ie. for
Jasypt lib org.jasypt.encryption and sub-packages?
Regards
Karsten

Hi Karsten,
Have you tried exporting interface org.jasypt.encryption.StringEncryptor?
I export this interface using a dedicated blueprint bundle and pass it the
decryption password from the environment. This service is then used by
pax-jdbc, and also referenced by other blueprint bundles which need to import
the jasypt namespace and use a property-placeholder to resolve the encrypted
entries.
Kind regards,
Geoff

Hi,
What do you mean by "not finding the service" ?
You mean at runtime (looking for service reference) or at deployment time (the
maven-bundle-plugin is generated req/cap for service, so it might be your
issue) ?
If you can share the message you have, it would be helpful.
Regards
JB
