In order to manage the correspondence between the Java class method name and the adapter class method name, the Java2cob command outputs a generation name management file (java2cob.mgt).
The generation name management file is generated in the adapter class output folder.
When you regenerate the adapter class from a Java class that you have used at least once, the Java2cob command inputs the generation name management file from the folder where the adapter class is stored.
When there is a change in the content of Java class, it is reflected in the generation name management file. When there is a postscript, it is recorded.
