The classpath is the list of JAR files that the Java runtime environment searches for classes and other resource files.
System Classpath: Identifies the path to the classes on your system.
Environment Classpath: Retain the default selection to ignore the CLASSPATH environment variable. The CLASSPATH environment variable is convenient for basic tutorials in programming, but is not recommended for enterprise environments.
Server Classpath: Examine this read-only field to view the Application Server classpath.
Classpath Prefix: To insert a JAR file into the beginning of the server’s classpath, enter the full path name of the file in this prefix field.
Classpath Suffix: To insert a JAR file into the beginning of the server’s classpath, enter the full path name of the file in this suffix field. For example, you would specify the JAR file of a database driver. See To integrate a JDBC driver.
Native Library Path Prefix: Prepend entries to the native library path.
Native Library Path Suffix: Append entries to the native library path.
The native library path is a concatenation of the server’s relative path for its native shared libraries, the standard JRE native library path, the shell environment setting (LD_LIBRARY_PATH on UNIX), and any path specified on the JVM Profiler Settings page.
