Getting directory in which app is deployed
Hi there, I have one problem... We have to execute external Java process from JAR archive included in our web application directory. The problem is, that all system dependant functions are relative to tomcat home directory. And - when our application is deployed outside tomcat directory via server.xml context definition - we cannot find a way to get path to our web directory... I am not sure if I am expressing myself clear, so example... I have web app with structure: someDir/web: WEB-INF META-INF dirWithArchive externalProgram.jar ... which is deployed OUTSIDE tomcat. I need to execute such code: Process = new ProcessBuilder(java -jar some/path/to/someDir/web/dirWithArchive/externalProgram.jar.split(\\s+).start(); from within struts action or struts plugin. HOW can I find a path without specifying it manualy (it's problematic because of different environments we deploy our application to).

Re: Getting directory in which app is deployed
If your webapp is deployed as an exploded app (ie not a .war file), ServletContext#getRealPath() should do the trick --David Wojciech Ciesielski wrote: Hi there, I have one problem...

Re: Getting directory in which app is deployed
have your external process use a script that points to the webdirectory or if you use servlets, set an init param in the web.xml or in server.xml set an environment variable: !-- Test entry for demonstration purposes -- Environment name=simpleValue type=java.lang.Integer value=30/ or set a session variable in a jsp Wojciech Ciesielski wrote: Hi there, I have one problem...
