The JVM is created using JNI, - and everthing runs in-process. - - Two examples are provided, jver and jawt, to illustrate usage of this - extension. A few things to note: - - 1) new Java() will create an instance of a class if a suitable constructor - is available. If no parameters are passed and the default constructor - is useful as it provides access to classes like "java.lang.System" - which expose most of their functionallity through static methods. - - 2) Accessing a member of an instance will first look for bean properties - then public fields. In other words, "print $date.time" will first - attempt to be resolved as "$date.getTime()", then as "$date.time"; - - 3) Both static and instance members can be accessed on an object with - the same syntax. Furthermore, if the java object is of type - "java.lang.Class", then static members - - 4) Exceptions raised result in PHP warnings, and null results. - - 5) Overload resolution is in general a hard problem given the - differences in types between the two languages. The PHP Java - extension employs a simple, but fairly effective, metric for - determining which overload is the best match. - - Additionally, method names in PHP are not case sensitive, potentially - increasing the number of overloads to select from. - - Once a method is selected, the parameters are cooerced if necessary, - possibly with a loss of data (example: double precision floating point - numbers will be converted to boolean). - -Build and execution instructions: - - Given the number of platforms and providers of JVMs, no single set of - instructions will be able to cover all cases. So in place of hard and - fast instructions, below are a working examples for a number of free and - commercial implementations and platforms. Please adjust the paths to - suit your installation. Also, if you happen to get this to work on - another JVM/platform combination, please let me know, particularly if - a unique build or execution setup was required. - - This function has been tested in both CGI and Apache (apxs) modes. As - the current design requires shared libraries, this support can not be - linked statically into Apache. - - With ext/java, no Java Virtual Machines are created until the first - Java call is made. This not only eliminates unnecessary overhead if - the extension is never used, it also provides error messages directly - back to the user instead of being burried in a log some place. - - For people interested in robustness, performance, and more complete - integration with Java, consider using the sapi/servlet interface which - is built upon the Java extension. Running PHP as a servlet enables PHP - to utilize the existing JVM and threads from the servlet engine, and - provides direct access to the servlet request and response objects. - -======================================================================== -=== JVM=Kaffe 1.0.4 (as delivered with OS), OS=Redhat Linux 6.1 === -======================================================================== - -build instructions: - - ./configure --with-java - -php.ini: - - [java] - java.library.path=/usr/lib/kaffe:/home/rubys/php4/modules - java.class.path=/usr/share/kaffe/Klasses.jar:/home/rubys/php4/modules/php_java.jar - extension_dir=/home/rubys/php4/modules - extension=libphp_java.so - -======================================================================== -=== JVM=Kaffe 1.0.5 (built from source), OS=Redhat Linux 6.1 === -======================================================================== - -build instructions: - - ./configure --with-java - -php.ini: - - [java] - java.library.path=/usr/local/lib/kaffe:/home/rubys/php4/modules - java.class.path=/usr/local/share/kaffe/Klasses.jar:/home/rubys/php4/modules/php_java.jar - extension_dir=/home/rubys/php4/modules - extension=libphp_java.so - -======================================================================== -=== JVM=IBM 1.1.8, OS=Redhat Linux 6.1 === -======================================================================== - -build instructions: - - ./configure --with-java - -php.ini: - - [java] - java.class.path=/home/jdk118/lib/classes.zip:/home/rubys/php4/modules/php_java.jar - extension_dir=/home/rubys/php4/modules - extension=libphp_java.so - -======================================================================== -=== JVM=Blackdown 1.2.2 RC4, OS=Redhat Linux 6.1 === -======================================================================== - -build instructions: - - ./configure --with-java - -php.ini: - - [java] - java.class.path=/home/rubys/php4/lib/php_java.jar - extension_dir=/home/rubys/php4/modules - extension=libphp_java.so - -======================================================================== -=== JVM=Sun JDK 1.2.2, OS=Linux === -======================================================================== - -This compiler is not supported at this time.
