Hello, 
do you mean that fat jar is not the best solution? How to use jar://URI? (maybe a simple example or a link where I can find some examples) Where exactly do I find the proposal?


Hi,

Although it is possible to fetch libraries from other jar files using a
jar:// URI, at least in the Sun Java platform, this feature may not work on
other platforms; GCC/GCJ uses ELF libs instead.

I think there's no use for this feature. If you're looking for a java module
system, read the proposal from the RICE people, which was inspired by the
SML/NJ. It uses real generics to build compound modules.

Hello Jost,
I am very sorry but I still can't solve the problem which I described
yesterday. I try to explain it again in other words, maybe I explained it
not very clearly.
Well there are many jars in one jar (fat jar) I don't have to change
anything in this structure, I need only to access the classes .
I tryed  to get it with java_require and got this error:
exception javax.servlet.ServletException: java.lang.RuntimeException: PHP

The video which you recommended is only about one "folder"with classes. In
my case it is not so.
As Ihave already written "jars in jar"(fat jar) and I must not change this
structure...
It does not work:
<?php
require_once("http://localhost:8081/Ordner/java/Java.inc");

$System = java("java.lang.System");

$myObj = new java("web.FacettenBrowser");
echo  $myObj->HalloWelt();
?>

Many thanks in advance!

I think this feature isn't useful for applications. The tomcat container
uses it to open the .war files:

<?php require_once("
http://localhost:8081/JavaBridgeTemplate5442/java/Java.inc");

echo
java("java.lang.Thread")->currentThread()->getContextClassLoader()->getResource("php/java/bridge/global.properties");
echo "\n";
?>

=>
jar:file:/home/opt/apache-tomcat-6.0.18/webapps/JavaBridgeTemplate5442/WEB-INF/lib/JavaBridge.jar!/php/java/bridge/global.properties

If you write your own class loader derived from url class loader, you may do
the same from PHP -- java_require uses an url loader, but it also needs a
timestamp.

There are several papers from rice.edu on this topic (java "link-time
components"), for example this one: http%3A%2F%2Fwww.cs.rice.edu
%2F~javaplt%2Fpapers%2Fsac2007.pdf
