Connection timeout with tomcat

Reply Contact

Hi,

I'm using Windows server 2003 with IIS6 and with tomcat6 connected with isapi_redirect-1.2.27

My java servlet uses batik to generate an image in png. The server has a static IP (of course) in the LAN, and it is connected to a router (with a public IP address).

Using the browser within the server using the LAN IP address to call the servlet, there is no problem: I can see the image displayed in the browser.

If I connect from outside the LAN (so using the public IP) I got the following connection time out error and so no image! From outside the LAN I am able to navigate through the other jsp pages and servlet.

What could be the causes?

Hosting the same files on another commercial hoster it works without errors.

Please help....

org.apache.batik.transcoder.TranscoderException: null
Enclosed Exception:
Connection timed out: connect
at org.apache.batik.transcoder.XMLAbstractTranscoder.transcode(XMLAbstractTranscoder.java:136)
at org.apache.batik.transcoder.SVGAbstractTranscoder.transcode(SVGAbstractTranscoder.java:156)

It sound like it could be a network/firewall/routing issue from that location.

Put a packet sniffer on it to see if IIS if there if teh file is being sent out of the network.

thanks, but I never used a packet sniffer: could you give me some instructions?

I found out that using the public IP address or localhost from a server browser it is not possible to reach neither the servlet nor the jsp and html pages. Could this give you any clue?

summarizing:

from outside the LAN using public IP: pages can be browsed but I got connection timeout
from the server using static IP (192.168.x.y): it works perfectly
from the server using public IP: unable to find any page
from the server using localhost: unable to find any page

Hi,Maxqua

Can you access your Tomcat6 directly without using "isapi_redirect-1.2.27"? if the problem produced the same, This problem may due to Network issue.

Regards.

I used the sniffer and the result is (I filtered the http protocol only):

384 6.355468 001D8BD516C2 LOCAL HTTP GET Request from Client 151.54.81.124 SERVER-WEB IP
877 27.314453 LOCAL 001D8BD516C2 HTTP Response to Client; HTTP/1.1; Status Code = 200 - OK SERVER-WEB 151.54.81.124 IP

The result is the same, the picture I am going to get is not displayed.
