What is PHP4 ext/java?
|
|
|
|
|
|
|
|
PHP4 ext/java provides a simple and effective means for creating and
|
|
|
|
invoking methods on Java objects from PHP. 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
|
2000-03-15 14:28:34 +00:00
|
|
|
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
|
2000-03-15 14:28:34 +00:00
|
|
|
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.

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.

This compiler is not supported at this time. At the moment, only green
|
|
|
|
threads are supported, requiring system calls to be wrapped, which is
|
|
|
|
incompatible with the JNI Invocation API. Once native threads are
|
|
|
|
supported, It is expected that the configuration will be identical to
|
|
|
|
the Blackdown JDK.
