My OS is Linux Redhat9.
I have downloaded and installed Tomcat 5.0.16 from a "binary" distribution. I created a build.properties file in my home directory as follows : manager.username=bkimelman manager.password=foobar manager.url=http://localhost:8080/manager I can successfully use ant to compile my tomcat application. I can successfully use ant to prepare a WAR file for distribution. I tried some of the sample applications that came with the tomcat installation and they all worked OK. I successfully used the manager webapp (via the Mozilla browser) to get a listing of all applications : http://localhost:8080/manager/list When I tried to install my webapp using ant I received the following error message : /home/bkimelman/tomcat1/build.xml:365: FAIL - Encountered exception java.util.zip.ZipException: error in opening zip file lines 361 - 365 are as follows : 361 : <deploy url="${manager.url}" 362 : username="${manager.username}" 363 : password="${manager.password}" 364 : path="${app.path}" 365 : war="file://${build.home}"/> However, when I used the manager webapp via the browser as follows : http://localhost:8080/manager/deploy?path=/tomcat1& war=file:/home/bkimelman/tomcat1/dist/tomcat1-1-dev.war I was successfull in deploying my application (and I was able to run my application). Any ideas as to why I can't use ant to install my tomcat application ?
