Having trouble with starting tomcat server in eclipse - java

I have a problem when starting TOmcat 6 server from eclipse, it pops up with the following message:
Server Tomcat v6.0 Server at localhost was unable to start within 45 seconds. If the server requires more time, try increasing the timeout in the server editor.

It could be that it just takes too long to start-up. You can check that from your logs to see whether it was midway through when the default 45 secs cutt-off time occurred. If so, on the Servers view double-click on the tomcat instance you are deploying and in the Overview tab, click on the Timeouts section on the right column and give your tomcat a bit more time to startup.

Tomcat silently dies resulting is 502 server error - running as container

Tomcat version: 8.0.47
Tomcat is running as a container using: "FROM tomcat:8.0.47" in the Dockerfile.
Tomcat starts up and is able to serve my web application with no problems.
After approximately 7-10 minutes, I get a 502 server error:
Error: Server Error
The server encountered a temporary error and could not complete your
request.
Please try again in 30 seconds.
When I check the container ps -ax, I still see tomcat process running.
When I check catalina logs, the last log line: INFO [main] org.apache.catalina.startup.Catalina.start Server startup in 72786 ms
When I check application-specific logs, there are no errors.
My expectation: How do I figure out what is wrong and why is it silently dying whilst the process is still active? There is 7 minutes of proof that the application & tomcat was deployed correctly since it works with no problems in the first 7 minutes of start up?

Timeout last 10 min in Tomcat 7

I have deployed a webapp in Tomcat 7, and I'm not using Eclipse, but when I run application last 10 min appear a timeout exception, exactly: Read timed out.
I've tried to change:
In web.xml:
session-timeout 30
In server.xml I added:
connectionTimeout="20000"
keepAliveTimeout="90"
Also I addes in startup.bin before #echo off:
CATALINA_OPTS=
-Dsun.net.client.defaultConnectTimeout=900000;
-Dsun.net.client.defaultReadTimeout=900000
I don't know what other parameter to configure, because always stop to 10 min.
Someone can I help me?
If you are using eclipse. Then goto server explorer and double click on your tomcat server.
It'll open a new tab inside your eclipse. There is Timeout section on the right side.
you can increase your session timeout time of tomcat server. without changing the server.xml
if it doesn't work follow below link

Eclipse Java EE + Bitnami Tomcat Stack

This is my situation:
Eclipse ide that i use to develop java web apps.
Tomcat from apache.
Tomcat stack from bitnami.
OS Windows 8
If i deploy and debug to the apache tomcat all work without problem.
If i try the same thing with the bitnami stack, i see the exact same output from the console, like it is starting well, but actually it doesn't and it gets to the timeout saying it was unable to start withing 45 seconds.
I tried to increase the timeout but that's not the problem.
In both cases the Server Location is set to Use Tomcat installation, and i added my project to the source, everything else in the server config is default.
I'm not an expert of tomcat and java webapp deploying, and i need to get it working with the bitnami stack.
Any hint will be appreciated.
Ok i solved it, seems more a problem from eclipse.
In the server configuration i noticed the HTTP port was not listed and it was commented in server.xml
Could this be because the bitnami stack uses port 80 instead of 8080?
Anyway setting the port 80 in server.xml solved the problem.

Tomcat server not starting. in eclipse

I am trying to host my web app through Tomcat. I am using the Spring framework and have Tomcat set up. I have converted it to a Maven project and one a Maven file and moved the war file to correct webapps folder in the Tomcat installation folder. When I try to run, it gives the me the error:
Server Tomcat v7.0 Server at localhost was unable to start within 45 seconds. If the server requires more time, try increasing the timeout in the server editor.
In the console, I see that it gets stuck on
Building JPA container EntityManagerFactory for persistence unit 'default'
I am using an MySQL database and in the MySQL workbench it says the server is running. I am really confused as to why this is happening. I have even tried the following:
Click on Window > Show view > Server OR right click on the server in "Servers" view, select "Properties".
In the "General" panel, click on the "Switch Location" button.
The "Location: [workspace metadata]" should replace by something else.
Open the Overview screen for the server by double clicking it.
In the Server locations tab , select "Use Tomcat location".
Save the configurations and restart the Server.
Can someone tell me why this is happening? Thanks for any help
Open the Servers Tab from Windows>Show View>Servers menu.
Right click on the server and delete it.
Create a new server by going New>Server on Server Tab.
Click on “Configure runtime environments…” link.
Select the Apache Tomcat v7.0 server and remove it. This will remove the Tomcat server configuration. This is where many people do mistake – they remove the server but do not remove the Runtime environment.
Click on OK and exit the screen above now.
From the screen below, choose Apache Tomcat v7.0 server and click on next button.
Browse to Tomcat Installation Directory.
Click on Next and choose which project you would like to deploy.
Click on Finish after Adding your project.
Now launch your server. This will fix your Server timeout or any issues with old server configuration. This solution can also be used to fix “port update not being taking place” issues.

the server requires more time to start but the default start time limit is 45 seconds .
All you have to do is open the servers tab, right click on your server and click open , a menu will be opened in your editor , open submenu Timeouts and change the value of Start (in seconds) to a higher value for example 300 seconds. and start your server again.
In my case, the problem came from an impossible loopback on localhost.
Tomcat effectively started (I could call "http://localhost:8080/myApp"), but Eclipse didn't get a response of that and it considered Tomcat keep on starting.
A software called ZScaler (set by admin to protect the enterprise) on Windows 10 put loopback restrictions. Fortunately, an option existed to disable loopback restrictions on ZScaler.
A VPN may cause the same restrictions.
If you don't find which application cause the trouble, you can change "Host name" in Eclipse's Tomcat General Informations, from "localhost" to "yourIP" (ex : 179.25.14.178), BUT this trick won't allow DEBUG MODE.

Tomcat 6 is in starting synchronised mode and shutsdown after timeout in eclipse juno

Tomcat logs INFO: Server startup in 181667 ms but never in started state as it is in starting and synchronised state. I'm using eclipse Juno. I have gone through related posts but the issue is not resolved.
I get the following error:
Server Liferay v6.0 CE Server (Tomcat 6) at localhost was unable to start within 900 seconds.
If the server requires more time, try increasing the timeout in the server editor.
Please let know the cause for this scenario.
You can increase your tomcat start time.
Click on double click on on your server find timeout option and increase your start time (in seconds)
Let me know if you have problem
