Compiling a Java PAPI Program

The following procedures show you how to compile from the command line a Java class that uses PAPI.

To compile a Java PAPI program from the command line you need to have a Java SE Development Kit 5 (JDK 5) installed. You can download the JDK from Sun Developer Network. You may also use the JDK bundled with some installations of ALBPM Enterprise, which gets installed under BEA_HOME/albpm6.0/enterprise/jre/.

PAPI classes are contained in the fuegopapi-client.jar JAR file, which is distributed with ALBPM Enterprise under BEA_HOME/albpm6.0/enterprise/client/papi/lib/fuegopapi-client.jar.

Open a command-line session.

Add the PAPI library to the classpath by setting the environment variable CLASSPATH. The way of doing this depends on your operating system.

Linux:

$export CLASSPATH="/bea/albpm6.0/enterprise/client/papi/lib/fuegopapi-client.jar"

Windows:

C:>set CLASSPATH="C:/bea/albpm6.0/enterprise/client/papi/lib/fuegopapi-client.jar"

Compile the Java PAPI program using javac (Java Compiler) provided by the JDK:
```
javac MyFirstPapiApplication.java
```
These two steps can be merged into one by using the -classpath option when calling the java compiler:
```
javac -classpath "C:/bea/albpm6.0/enterprise/client/papi/lib/fuegopapi-client.jar" MyFirstPAPIApplication.java
                    
```

A file with the extension .class is generated in the directory where you compiled your program.
