Hello, In the documentation for the Java API, the preModification method states that it is run before data is modified by the service. However, if you delete a service, preModification is run after the service has been deleted and the data modified. It seems that the preModification method should still run before the service is deleted from the CDB. Is this a bug or intended behavior? Thanks

Additional info: Message from the CLI when its run: admin@ncs(config-servicelookup-1231)# commit dry-run Aborted: application timeout In addition, the errors in the ncs-java-vm.log come after the service is run - the errors show up when opaque is returned.

Hello, I am trying to configure a service from within a separate service using MAAPI. MAAPI is successfully connecting and applying transactions, but is running until a timeout (a couple minutes) after it completes applying the transaction. I get the following error message: <ERROR> 21-Apr-2016::08:39:29.621 ConfInternal NCS-DpMUX-108-servicelookup:RFSSkeleton: - Unexpected end of file (EOF) when reading the stream from socket <ERROR> 21-Apr-2016::08:39:29.621 Dp NCS-DpMUX-108-servicelookup:RFSSkeleton: - com.tailf.conf.ConfException: unexpected end of file at com.tailf.conf.ConfInternal.readFill(ConfInternal.java:434) at com.tailf.conf.ConfInternal.termRead(ConfInternal.java:189) at com.tailf.conf.ConfInternal.termRead(ConfInternal.java:114) at com.tailf.dp.Dp.read(Dp.java:1704) at com.tailf.ncs.ctrl.NcsDpMux.run(NcsDpMux.java:175) at java.lang.Thread.run(Thread.java:745) Caused by: java.io.EOFException ... 6 more <WARN> 21-Apr-2016::08:39:29.621 NcsDpMux NCS-DpMUX-108-servicelookup:RFSSkeleton: - Error in NcsDpMux com.tailf.conf.ConfException: unexpected end of file at com.tailf.conf.ConfInternal.readFill(ConfInternal.java:434) at com.tailf.conf.ConfInternal.termRead(ConfInternal.java:189) at com.tailf.conf.ConfInternal.termRead(ConfInternal.java:114) at com.tailf.dp.Dp.read(Dp.java:1704) at com.tailf.ncs.ctrl.NcsDpMux.run(NcsDpMux.java:175) at java.lang.Thread.run(Thread.java:745) Caused by: java.io.EOFException ... 6 more I am closing the socket in a finally block, and Im also doing maapi.finishTrans(). All configuration is written and the other service applies as expected. The error really doesnt seem to be impacting the functionality besides making the service take much longer to build then it should. Any ideas on what is causing the EOF errors and how to stop them?

I dont believe you can do that kind of validation there (or I havent found a way yet) - you can do it in Java though when the service is called. Not sure it matters much there as it would fail anyways depending on what you were doing.

Figured out the issue. You have to either place the JARs with dependencies in the $NCS_DIR/java/jar folder and call them appropriately or edit the build.xml files to add a new folder.

I am trying to integrate an OpenStack API JAR (OpenStack4j) in to NSO so I can import the classes I need for services (template and java based). I have tried adding the JAR to $NCS_DIR/java/jar so that the build.xml file uses it, and have tried unzipped the JAR into the package java/src directory and neither are letting me import the classes in to the service JAVA file (com/example/serviceName/serviceNameRFS.java). I have also tried adding the CLASSPATH in to the Makefile. No matter what I do, when I make the service, it cannot import the classes. Can anyone point me in the right direction? Thanks

I solved this problem using Java as part of the service. You can use the NAVU API to iterate through the devices YANG model in all of the areas that the device would store VLANs and add them to a HashSet, and then compare that HashSet to a set range you want to use for service configuration. You will need to do a check of the device itself to determine which YANG model you need to use for that device and write code to find all of the VLANs. I wrote it for Cisco IOS and IOS-XR as part of a Cisco class to gather this kind of data (I didnt have the resource manager when I started). Once you have the VLANs its simple to choose one or take any action. You can narrow it down to finding only the used VLANs on the interface you will configure, or you can find all globally used VLANs if necessary depending on the service. Using the NAVU API, you can find just about anything. As long as your devices are kept in sync with NSO you shouldnt have any issues.
