Hi André, Yes, whatever your understanding is correct. And also the connector tag is inside of Tomcat B.

Ok, so I understand that it is your web application A, running inside your Tomcat B, which tries to access another webserver C. And application A, to connect to webserver C, is using a httpclient object for that.

Do you mean that the browser (D) can connect directly to webserver C ? But that when application A tries to connect to webserver C, you have the error below ? (java.net.ConnectException: Connection refused: connect..) but not through application). To solve this issue, we modified the connector tag in the server.xml file. > > <Connector port="7070" maxHttpHeaderSize="8192" > maxThreads="150" minSpareThreads="25" > maxSpareThreads="75" > enableLookups="false" redirectPort="8443" acceptCount="100" > connectionTimeout="20000" > disableUploadTimeout="true" address="0.0.0.0" /> > Still to make things clear : is this <Connector> inside of Tomcat B, or is it the connector of the other webserver C ? > As, it can be seen from above we have added address="0.0.0.0" in the > connector tag, by doing so we were able to connect. > > Now, as per the new requirement, we are upgrading our tomcat from 5.5.30 to > 7.0.14(Since the folder structure is changed, we are shipping the fresh copy > of tomcat).
