Hi Karsten, You base bundle looks ok.
My importing blueprint bundle does the following: 1) References this namespace xmlns:enc="http://karaf.apache.org/xmlns/jasypt/v1.0.0" 2) Configures the string encryptor service reference <reference id="encryptor" interface="org.jasypt.encryption.StringEncryptor"/> <enc:property-placeholder encryptor-ref="encryptor"/> 3) To decrypt values like this <cm:property name="password" value="ENC(some_encryted_value)"/> The above works with Karaf 4.2.4 and 4.3.6 running on Linux or Win 7, other combinations I'm not sure. (Note that the service id is local to the blueprint container) Geoff -----Original Message----- From: Karsten Blume <karsten.bl...@ottoint.com> Sent: 04 April 2022 11:00 To: user@karaf.apache.org Subject: AW: Exporting an instance of a 3rd party library as service 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 ----Ursprüngliche Nachricht----- Von: Geoffrey Seanor <geoffrey.sea...@mufgsecurities.com> Gesendet: Montag, 4. April 2022 10:23 An: user@karaf.apache.org Betreff: RE: Exporting an instance of a 3rd party library as service 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.

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.
