Where to Put Your Classes and Jar Files
If you are using your own classes developed by your company or classes from a third-party library, you can control the visibility and loading order of these classes. Class visibility refers to whether the classes and jar files will be or need to be visible to all the classes in Integration Server or to a particular package only.
Use the following guidelines to help you decide where to put your class files and jar files.
If a class or jar file is needed only by services in one
Integration Server package, put it in the package's code/classes or code/jars directory.
If a class or jar file is needed by a second
Integration Server package, keep the class or jar in the package that it already resides in and establish a package dependency on the first package. You can accomplish this by using
Designer to establish a dependency on the first package from the second package or by modifying the second package's manifest.v3 file to require the first package.
If additional
Integration Server packages need the class or jar file, and the package dependencies are becoming difficult to manage, do one of the following:
If it is a jar or zip file, move it to the package's code/jars/static directory. This will add the jar or zip to the server's classpath and make it available to all packages.
If it is a class or a set of classes, add the full path to the parent directory in one of these lines in the following file:
Software AG_directory \profiles\IS_
instanceName\configuration\custom_wrapper.conf
wrapper.java.additional.202=-Dwatt.server.prepend.classes=
wrapper.java.additional.203=-Dwatt.server.append.classes=
If your package needs a different version of a class or jar file than one that resides in another package, copy the version you need to your package's code/classes or code/jars directory.
If your package needs a different version of a class or jar file than one that is on the server classpath, do the following:
1. Copy the version you need to your package's code/classes or code/jars directory.
2. Change your package's classloader property to "package". For more information about
