[PHP-DEV] PHP 4.0 Bug #8202 Updated: exec("java -cp classpath classname inputArgument"); has no effect From: Lee.Seldon <email protected>
Date: 03/13/01

ID: 8202
User Update by: Lee.Seldon <email protected>
Old-Status: Feedback
Status: Open
Bug Type: *Function Specific
Description: exec("java -cp classpath classname inputArgument"); has no effect

ID 8202
I don't get any error messages.
A student of mine tried the code on his system, and claimed it worked.
Using 4.0.3 as CGI installation

Not urgent - our work-around -> re-wrote the Java code in PHP, and that works.

are you not getting any errors?? Can you try exec with other programs and see if it happens with them?

Not getting a unable to fork eror are you? what SAPI are you using ISAPI or CGI?

The command prompt line
java -cp .;C:Javabin;C:Javalib;C:Javalibtools.jar;E:Health_InfoHealthWebDirectoryMessages HTML_HL7translator E:Health_InfoHealthWebDirectoryMessagesDischargeDis-2000-11-28-1.htm

runs the java class HTML_HL7translator with input file Dis-2000-11-28-1.htm
jdk1.3 is installed and works

None of the commands in the following cause HTML_HL7translator to run:

<?php
$javaHL7 = exec("java -cp .;C:Javabin;C:Javalib;C:Javalibtools.jar;E:Health_InfoHealthWebDirectoryMessages HTML_HL7translator E:Health_InfoHealthWebDirectoryMessagesDischargeDis-2000-11-28-1.htm");
echo "did execn";
passthru("java -cp .;C:Javabin;C:Javalib;C:Javalibtools.jar;E:Health_InfoHealthWebDirectoryMessages HTML_HL7translator E:Health_InfoHealthWebDirectoryMessagesDischargeDis-2000-11-26-2.htm");
echo "did passthrun";
$javaHL7s = system("java -cp .;C:Javabin;C:Javalib;C:Javalibtools.jar;E:Health_InfoHealthWebDirectoryMessages HTML_HL7translator E:Health_InfoHealthWebDirectoryMessagesDischargeDis-2000-11-26-4.htm");
echo "did system()";
?>
