Hello everyone, i've created a simple class reading values from a ModBus PLC.
I'm trying to use it inside Karaf, but at start the class is unable to find the modbus driver. I've compiled and installed in Karaf the "driver-s7-feature", with added the modbus driver: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <features xmlns="http://karaf.apache.org/xmlns/features/v1.6.0" name="driver-s7-feature"> <feature name="driver-s7-feature" description="PLC4J: Karaf-Features: S7" version="0.8.0.SNAPSHOT"> <details>Implementation of the protocol adapters for usage as Java library.</details> <bundle>mvn:org.apache.plc4x/plc4j-osgi/0.8.0-SNAPSHOT</bundle> <bundle>mvn:org.osgi/osgi.core/6.0.0</bundle> <bundle>mvn:org.apache.plc4x/plc4j-api/0.8.0-SNAPSHOT</bundle> <bundle>mvn:org.apache.plc4x/plc4j-spi/0.8.0-SNAPSHOT</bundle> <bundle>mvn:io.netty/netty-codec/4.1.47.Final</bundle> <bundle>mvn:io.netty/netty-common/4.1.47.Final</bundle> <bundle>mvn:io.netty/netty-transport/4.1.47.Final</bundle> <bundle>mvn:io.netty/netty-resolver/4.1.47.Final</bundle> <bundle>mvn:commons-beanutils/commons-beanutils/1.9.4</bundle> <bundle>mvn:commons-logging/commons-logging/1.2</bundle> <bundle>mvn:commons-collections/commons-collections/3.2.2</bundle> <bundle>mvn:com.github.jinahya/bit-io/1.4.3</bundle> <bundle>mvn:commons-codec/commons-codec/1.12</bundle> <bundle>mvn:org.apache.plc4x/plc4j-driver-s7/0.8.0-SNAPSHOT</bundle> <bundle>mvn:org.apache.plc4x/plc4j-driver-modbus/0.8.0-SNAPSHOT</bundle> <bundle>mvn:org.apache.plc4x/plc4j-transport-tcp/0.8.0-SNAPSHOT</bundle> <bundle>mvn:com.fasterxml.jackson.core/jackson-annotations/2.10.0</bundle> <bundle>mvn:org.apache.commons/commons-lang3/3.9</bundle> <bundle>mvn:io.netty/netty-buffer/4.1.47.Final</bundle> <bundle>mvn:io.vavr/vavr/0.10.2</bundle> <bundle>mvn:io.vavr/vavr-match/0.10.2</bundle> </feature> </features> Inside Karaf i can find all the active bundles: 152 │ Active │ 80 │ 0.8.0.SNAPSHOT │ PLC4J: API 153 │ Active │ 80 │ 0.8.0.SNAPSHOT │ PLC4J: Driver: S7 (Step7) 154 │ Active │ 80 │ 0.8.0.SNAPSHOT │ PLC4J: OSGi 155 │ Active │ 80 │ 0.8.0.SNAPSHOT │ PLC4J: SPI 156 │ Active │ 80 │ 0.8.0.SNAPSHOT │ PLC4J: Transports: TCP 157 │ Active │ 80 │ 6.0.0.201403061837 │ osgi.core 164 │ Active │ 80 │ 1.0 │ edgecontroller Bundle 165 │ Active │ 80 │ 0.8.0.SNAPSHOT │ PLC4J: Driver: Modbus Anyway at startup the bundle doesnt find any driver: 2020-06-08T17:47:43,391 | INFO | FelixStartLevel | PlcDriverManager | 152 - org.apache.plc4x.plc4j-api - 0.8.0.SNAPSHOT | Instantiating new PLC Driver Manager with class loader sun.misc.Launcher$AppClassLoader@764c12b6 2020-06-08T17:47:43,391 | INFO | FelixStartLevel | PlcDriverManager | 152 - org.apache.plc4x.plc4j-api - 0.8.0.SNAPSHOT | Registering available drivers... 2020-06-08T17:47:43,392 | ERROR | FelixStartLevel | Activator | 164 - edgecontroller - 1.0.0 | Unable to find driver for protocol 'modbus' edgecontroller is my bundle, looking at the Karaf log the PlcDriverManager is unable to find any driver. I cannot understand were i'm failing, could anyone provide some insight? Thank you, Ale
