A Java Problem...

Hi All:) I'm new in this maillist and php. But I encounter some problems when I want to use the java extension in php4beta, So I go here and ask. Here is my problem: There's a example file in the php4betapl1 packages in ext/java/ directory, jver.php. When I tried to load the page on the browser, the following messages appeared: Fatal error: Cannot instanciate non-existant class: java in /home/jdchiou/test1/htdocs/jver.php on line 3 And, I have different situation when I tried these for the first time: I even can't start the apache web server. the following lines are added into my web server error log file: PHP Fatal error: Unable to load dynamic library '/tmp/php-4.0b4pl1/modules/libp hp_java.so' - /tmp/php-4.0b4pl1/modules/libphp_java.so: undefined symbol: JNI_GetDefaultJavaVMInitArgs in Unknown on line 0 Can someone tell me what's going on about it? I compiled apache and php4 myself, using a RedHat platform, and Kaffe 1.0.5( coming from the redhat cd-rom ). My apache is compiled to a DSO mode. (Is this the right mode that the ext/java/README file said ?) Thank you all in advanced. And sorry about my poor English. Hsin-Mu Tsai Department of CSIE, National Taiwan University
