I have gone through similar problems faced by people but the solutions given to them doesnot work for me. For eg similar issue,
but the discussion there didn't helped me.

Please Note
My tomcat is installed in correct location as mentioned in build.xml file and also i have included

<role rolename="manager-script"/>
<user username="tomcat" password="s3cret" roles="manager-script"/>

in my tomcat-users.xml file.

Please help

[Andreas Koenig]

works for me, but are you sure about the port 80 in tomcat.manager.url in the build.properties because default it's 8080, unless you changed it in tomcat's server.xml

[Maan Suraj]

Yes I am sure. I changed the port to 80 from 8080. Also, i have deployed other application in the same tomcat and it works fine for me. It's only this ant build which fails

[Andreas Koenig]

After changing the port to 80 I get the same exception, maybe because it's default http-port. You should simply use another port.

[Maan Suraj]

Well thanks. This did helped up to some extent. I changed the port to 8180 and ant build works fine now. Now i got to know that the error which i mentioned occurs if i start tomcat from eclipse. Neveetheless,I learnt about the other exception which occurs when port is 80. Let me explain it below

1) With port "80" and if i start tomcat from outside(not from eclipse), then i get below error if i execute "ant list"

        at sun.net.www.http.HttpClient.New(HttpClient.java:323)
        at sun.net.www.protocol.http.HttpURLConnection.getNewHttpClient(HttpURLC

Now i changed the port to 8180, do an ant build and it works absolutely fine.

But if i start tomcat from eclipse (even with new port 8180) ,and do an ant build, then still i get the same old exception which i mentioned in previous post

[Andreas Koenig]

Don't know if you kept in mind that from within eclipse the webapps gets deployed temporarily inside the workspace, for me it's .metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps

[Andreas Koenig]

found a solution. the problem is like I said the webapps-folder within the workspace and the missing manager app. you need to add the folowing line to the server.xml in your workspaces server/tomcat folder
... <Context antiJARLocking="false" antiResourceLocking="false" docBase="C:/Program Files/apache-tomcat/webapps/webapps/manager" path="/manager" privileged="true" reloadable="false"/> </Host> </Engine> </Service> </Server>
and restart the server

[Maan Suraj]

I think we may be little closer to the solution. As you said, i gave below in my server.xml (in workspaces server/tomcat folder )

<Context antiJARLocking="false" antiResourceLocking="false" docBase="C:/Program Files/Apache Software Foundation/Tomcat 7.0/webapps/manager" path="/manager" privileged="true" reloadable="false"/>

Now i get below exception

I even tried with giving below in tomcat-users.xml file(in workspaces server/tomcat folder )

<role rolename="manager-script"/>
<user username="tomcat" password="s3cret" roles="manager-script"/>

[Andreas Koenig]

seems like it's nearly working. my tomcat-users.xml has the entries already, apparently imported when I created the server in eclipse. did you restartet the server after editing?

[Maan Suraj]

Ya i restarted the server

[Maan Suraj]

Well i just cleaned it and restarted the server....and now my build works fine Thanks a lot for some great suggestions
