Hello all,
I am working on a system with Bahmni 0.93 on Centos 7. I have been trying to fix some issues with the logging in our system. I found that the pacs-integration service isn’t generating logs correctly. After the pacs-integration service starts, the /var/log/pacs-integration/pacs-integration.log file has the following lines:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
Then the libraries used by the web app (like the atomfeed libraries) will generate log messages, but the log messages in the app itself don’t show up in the log file.
After searching, I found this is because the java web service is missing the dependency log4j-slf4j-impl which is “is a bridge between SLF4J 1.x (up to 1.7.x) and Log4j 2.x.” (from stackoverflow). I added the following to the pacs-integration-webapp/pom.xml file and now it seems to be working:
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-slf4j-impl</artifactId>
<version>${log4j.version}</version>
</dependency>
