am trying to implement an OSGI service which can serve me as ConfigurationFactory the service implementation has just two properties as shown below.

@Property(value="this is service variable property value") static final String MY_SERVICE_VARIABLE = "service.variable"; @Property(description="Label for this MyService") private static final String MY_SERVICE_LABEL = "service.label";

and am retrieving this service configuration data from an OSGI servlet where i am trying to call this service by below code which compiles fine and retrieves data randomly from the multiple service configuration.

@Reference MyService myservice;

But when i wanted to get each configuration data by using the service.label and am calling the service by using below code snippet in my OSGI servlet, while compiling am facing the below Error.

@Reference("(service.label=TESTCALL)") MyService myservice;

cannot find symbol [ERROR] symbol: method value() [ERROR] location: @interface org.apache.felix.scr.annotations.Reference.

Daniel is correct - i went through this and this works:

public class SimpleServlet extends org.apache.sling.api.servlets.SlingAllMethodsServlet {
private static final long serialVersionUID = 2598426539166789515L;

@Reference(target = "(mailservice.label=InternetA)")
MailService mailService;

We are turning this all into a HELPX Article so all the steps are included.

I have emailed you all the code so you can see it while the article (that uses the code that works perfectly fine) is written.

No problem, kk. I've done something similar before. It's also possible to dynamically set the target property (making the value used as a LDAP filter configurable), but I'm far away from my computer to send you a running sample. Regards, Daniel.

We will have complete article and video out next week - thank you for bringing this Doc Gap to our attention. This is how a great community works! Most of the HELPX content were driven from threads like this.

I was able to get both configurable services working based on my posted value to the servlet.
