RE: Tomcat is not able to connect to IPV4 (Tomcat Version : 7.0.14)
I really apologize for the confusion created. We are having an application, which is deployed on tomcat. Rather we are shipping the application with tomcat. After extraction (complete installation), the application is placed under the webapps directory. The logs that I have shared is from the console, while debugging the application. To summarize more, we were facing a similar kind of problem in an earlier version of tomcat when we upgraded it from 5.5.26 to 5.5.30 (We were able to access the link through browser, but not through application). To solve this issue, we modified the connector tag in the server.xml file. Connector port=7070maxHttpHeaderSize=8192 maxThreads=150 minSpareThreads=25 maxSpareThreads=75 enableLookups=false redirectPort=8443 acceptCount=100 connectionTimeout=2 disableUploadTimeout=true address=0.0.0.0 / 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). We have modified the connector tag as we have done for 5.5.30, but still no success. Please let me know if I am missing something or you want more information for the same.

Rohan Kadam wrote: Hi André, Yes, whatever your understanding is correct. And also the connector tag is inside of Tomcat B. Ok, then Charles' earlier message was correct, and the problem has nothing to do with Tomcat per se. Your web application A makes its own TCP connection to webserver C, using the Apache httpclient. It does not use any of the Tomcat network code for that. (In particular, it does not use the Tomcat Connector). It would be the same if your web application A was a stand-alone Java application, running outside of Tomcat. It is a mystery why, in your previous installation, changing the Tomcat Connector settings was changing the behaviour, but it has nothing to do with the issue you are dealing with now, as far as I can see. What you should maybe try : Outside of Tomcat, from a console on the same host as Tomcat B, try to run a console application to connect to the URL on server C. For example, use wget or curl, with the same target URL as what you used with the browser. Maybe the Tomcat host simply cannot access server 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). We have modified the connector tag as we have done for 5.5.30, but still no success. Please let me know if I am missing something or you want more information for the same.

Re: Tomcat is not able to connect to IPV4 (Tomcat Version : 7.0.14)
2011/6/30 Rohan Kadam roha...@cybage.com: Hi All, We had recently upgraded tomcat from 5.5.30 to 7.0.14. We were earlier facing problem that tomcat was not able to connect using Static IP address. The fix that we found was adding address = 0.0.0.0 in the Connector tag of server.xml in the conf directory. 1) What exactly is not able? Do you have a stacktrace? Maybe some other process already uses that port number? Was the value for address a correct one? Connector port=7070 maxHttpHeaderSize=8192 maxThreads=150 minSpareThreads=25 maxSpareThreads=75 enableLookups=false redirectPort=8443 acceptCount=100 connectionTimeout=2 disableUploadTimeout=true address=0.0.0.0 / 2) What exactly connector is being used? In your configuration Tomcat autoselects between two: Http11Protocol or Http11AprProtocol - which one is actually used is mentioned in the logs. After upgrading tomcat to 7.0.14, we have done the same process, but we are not able to connect. we have done the same process means you are trying to use 0.0.0.0 like you did with 5.5 and now it fails? (or that you tried your proper network address and failed with that, but 0.0.0.0 works)? The OS we found these issues are Win XP, Win 2008.
