opcmsg Java API

The JAR files jopcagtbase.jar and jopcagtmsg.jar that are necessary to use the APIs are installed as part of HPE Operations Agent on the Operations Connector server at:

Windows: %OvInstallDir%\java

Linux: /opt/OV/java

To use the Java classes:

• The -classpath parameter used for the javac and java commands must include the jopcagtbase.jar and jopcagtmsg.jar files.

• The PATH system variable must include the directory where the shared library files reside. The agent installation does this automatically.

Javadoc style class documentation is available at the following location:

Windows: %OvInstallDir%\www\htdocs\jdoc_agent\index.html

Linux: /opt/OV/www/htdocs/jdoc_agent/index.html

For more information, see the section "Java API" in the HPE Operations Agent Reference Guide PDF.

Examples of how the API classes can be used from Java are available in the following directory on the Operations Connector server:

Windows: %OvInstallDir%\examples\jopcagtapi

Linux: /opt/OV/OpC/examples/jopcagtapi

To compile and run the example code on Windows

1. Change to the folder %OvInstallDir%/examples/jopcagtapi on the Operations Connector server.

2. Compile the example code, type:

   javac -classpath "%OvInstallDir%/java/jopcagtbase.jar:%OvInstallDir%/java/jopcagtmsg.jar" JOpcAgtMsgTest.java

3. Run the example code, type:

   java -classpath ".:%OvInstallDir%/java/jopcagtbase.jar:%OvInstallDir%/java/jopcagtmsg.jar" JOpcAgtMsgTest

To compile and run the example code on Linux

1. Change to the directory /opt/OV/OpC/examples/jopcagtapi on the Operations Connector server.

2. Compile the example code, type:

   javac -classpath "/opt/OV/java/jopcagtbase.jar:/opt/OV/java/jopcagtmsg.jar" JOpcAgtMsgTest.java

3. Run the example code, type:

   java -classpath ".:/opt/OV/java/jopcagtbase.jar:/opt/OV/java/jopcagtmsg.jar" JOpcAgtMsgTest
