Problem with Runtime.getRuntime() exec
I have deployed a webservice using Axis2. It works fine, but ....
Here is a problem: I need to run an external program through the Client, so
I've put in existing library piece of code, which contains
Runtime.getRuntime(). When I run test, it works fine, but no external
program is run. It seems like piece of code with "Runtime rt =
Runtime.getRuntime();"(it works when is run locally) just ignored...
Could anyone help me with this issue?
This is class to be wrapped :
package eu.project.samplewebservice;
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
public class SampleExistingLibrary {
/**
* Adds two input integer parameters and returns the result.
*
* @param i1
* An integer input
* @param i2
* An integer input
* @return The integer result which is the sum of the two input integers
*/
public int addTwoIntegers( int i1, int i2 ) {
System.out.println( "TEST!!!!!!" );
///!!!!!!!!!!!
String mkcolpath = System.getenv("MKCOLPATH");
String pafpath = System.getenv("PAFPATH");
//System.out.print(mkcolpath);
try
{
Runtime rt = Runtime.getRuntime();
Process proc = rt.exec("supertux");
//this is a game
//pathToCollectionF = pafpath+"/collection.mf";
InputStream noerr = proc.getInputStream();
InputStream stderr = proc.getErrorStream();
InputStreamReader isr = new InputStreamReader(stderr);
BufferedReader br = new BufferedReader(isr);
InputStreamReader isr1 = new InputStreamReader(noerr);
BufferedReader br1 = new BufferedReader(isr1);
String line = null;
//System.out.println("<OUTPUT>");
while ( (line = br1.readLine()) != null || (line =
br.readLine()) != null){
System.out.println(line);
}
//System.out.println(line);
//System.out.println("</OUTPUT>");
int exitVal = proc.waitFor();
//exitValCl=exitVal;
System.out.println("Process exitValue: " + exitVal);
} catch (Throwable t)
{
t.printStackTrace();
}
///!!!!!!!!!!!
return i1 + i2;
}
/**
* Concatenates two input string parameters and returns the result.
*
* @param s1
* A string input
* @param s2
* A string input
* @return The string result which consists of two input strings, with

*/
public String concatenateTwoStrings( String s1, String s2 ) {
return s1 + s2;
}
}

Re: Problem with Runtime.getRuntime() exec
Posted by Andreas Veithen <an...@gmail.com>.
The way to set up environment variables for Tomcat depends on how you
start Tomcat. If you use the standard Ubuntu package, probably the
best way is to add the following line to /etc/default/tomcatX.X:
export ENV_VARIABLE=...
Note that (on Linux) /etc/environment is only read by pam_env during
interactive logins. This means that variables defined there will not
be available to processes started by the SysV init scripts.

Re: Problem with Runtime.getRuntime() exec
Posted by artifex <e6...@bsnow.net>.
Thank you, Andreas
I've checked environ:
sudo netstat -anp | grep 8080 // got PID by this comand
sudo cat /proc/<PID>/environ
The ouput is the same as I received by the webservice (...that snippet,
which prints all env variables). So it's just another way to check(not to
add or edit) what env variables are avaliable in runtime for your
webservice, but the problem isn't solved...still the same question:
***********How to set up your own environment variable, which you would like
to use(var=System.getenv(ENV_VARIABLE);) inside some class of your web
service ?*******************************

Re: Problem with Runtime.getRuntime() exec
Posted by Andreas Veithen <an...@gmail.com>.
If System.getenv returns null, then this means that the environment
variable is not set on the process. This has nothing to do with class
loaders or the fact that you look up the variable from within a
service. You can check that by looking at /proc/<pid>/environ, where
<pid> is Tomcat's process ID.

Re: Problem with Runtime.getRuntime() exec
Posted by artifex <e6...@bsnow.net>.
Things in use:
Ubuntu 9.04 (jaunty)
Tomcat 6 (deb package)
Axis2
Maven
Eclipse
other
....
There is some other information:
System.getenv("ENV_VARIABLE") will return null in this case, because the
variable doesn't exist.
if we run this snippet inside some class, which is part of our web service:
Map map = System.getenv();
Set keys = map.keySet();
Iterator iterator = keys.iterator();
while (iterator.hasNext()) {
String key = (String) iterator.next();
String value = (String) map.get(key);
System.out.println(key + " = " + value);
--- we will get a list of environment variables and this list is different
from that you get in command line : env
(I'm using Ubuntu)
Even if I set up my own env variable under root(for example like this:
sudo gedit /etc/environment
ENV_VARIABLE=/home/user/some_folder //put this line in /etc/environment and
save then reboot
) --- then rebuild and redeploy service(just in case) which contains class
with above snippet, I cannot see ENV_VARIABLE in output of tomcat console
(catalina.sh run)
So now the question is :
***********How to set up your own environment variable, which you would like
to use(var=System.getenv(ENV_VARIABLE);) inside some class of your web
service ?*******************************

Re: Problem with Runtime.getRuntime() exec
Posted by Deepal Jayasinghe <de...@opensource.lk>.
Hmm, I am not so sure that has something to do with the class loader, if
that is the case then problem might be due to each service has its own
class loader and it is different from context class loader. Anyway as I
remember correct no one asked this kind of question before, so if you
find that answer please post that too.
Thanks,
Deepal

That thing didn't work because it couldn't find path to the desired program
for execution.
I'm using environment variables in my java code("String envV =
System.getenv("ENV_VARIABLE");"), but it seems that getenv() cannot find
the variable. I'm sure it's set up correctly. So now my goal is to find out
how we can get environmental variables if classes which try to get it are
inside a web service(???)...
