hi there
I am trying to execute javac command from my servlet but it not letting me
do it . i am using tomcat server. here is the code wht i am trying to run:
Process proc1=null;
Runtime rt1 = Runtime.getRuntime();
proc1 = rt1.exec(new
String[]{"javac","/vol1/people/dinesh/jakarta-tomcat-4.0.6/webapps/examples/WEB-INF/classes/HelloWorldExample.java"});
BufferedReader err1 = new BufferedReader(new
InputStreamReader(proc1.getErrorStream()));
String line1 = null;
while ( ( line1 = err1.readLine()) != null)
out.println( line1);
and the error i get is:
/vol1/people/dinesh/jakarta-tomcat-4.0.6/webapps/examples/WEB-INF/classes/HelloWorldExample.java:8:
package javax.servlet does not exist import javax.servlet.*; ^
/vol1/people/dinesh/jakarta-tomcat-4.0.6/webapps/examples/WEB-INF/classes/HelloWorldExample.java:9:

if i run this command in my unix shell it works fine but not when i try to
run this command from servlet. i have a copy of servlet.jar file in lib
directory of tomcat and a classpath to it is also set in my .login file.
please advice wht need to be done?
thanks
dinesh
