The command prompt line
java -cp .;C:\Java\bin;C:\Java\lib;C:\Java\lib\tools.jar;E:\Health_Info\HealthWebDirectory\Messages HTML_HL7translator E:\Health_Info\HealthWebDirectory\Messages\Discharge\Dis-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:

$javaHL7 = exec("java -cp .;C:\Java\bin;C:\Java\lib;C:\Java\lib\tools.jar;E:\Health_Info\HealthWebDirectory\Messages HTML_HL7translator E:\Health_Info\HealthWebDirectory\Messages\Discharge\Dis-2000-11-28-1.htm");
echo "did exec\n";
passthru("java -cp .;C:\Java\bin;C:\Java\lib;C:\Java\lib\tools.jar;E:\Health_Info\HealthWebDirectory\Messages HTML_HL7translator E:\Health_Info\HealthWebDirectory\Messages\Discharge\Dis-2000-11-26-2.htm");
echo "did passthru\n";
$javaHL7s = system("java -cp .;C:\Java\bin;C:\Java\lib;C:\Java\lib\tools.jar;E:\Health_Info\HealthWebDirectory\Messages HTML_HL7translator E:\Health_Info\HealthWebDirectory\Messages\Discharge\Dis-2000-11-26-4.htm");
echo "did system()";

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?

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.

 [2001-03-14 15:08 UTC]
Can you please tell which SAPI you're using, ISAPI or CGI?


 [2001-03-14 17:18 UTC] Lee dot Seldon at infotech dot monash dot edu dot au
Using CGI, i.e. php.exe with the correspondng extension (.php) in the IIS 4 list pointing to php.exe %s %s
C:\Java\bin, etc are in the CLASSPATH (system environment setup)
 [2001-05-07 12:16 UTC]
Does your problem persist with PHP 4.0.5? Have you considered using PHP 4's Java extension to directcly invoke your Java class?

 [2001-06-01 16:04 UTC]
No feedback. Consider updating to PHP 4.0.6 when it is released.
