Firefox can't establish a connection to the server at localhost:8080

Ashhere · 03-07-2009, 12:13 PM

Hi,

I installed j2sdk1.4.2_03 and xampp-linux-1.6.8a on RHEL5. Since I could'nt run a jsp script on the server, I suppose xampp does not support jsp. So I installed apache-tomcat-6.0.18.

In terminal,

[root@localhost ~]# /etc/apache-tomcat-6.0.18-src/bin/startup.sh
Using CATALINA_BASE: /etc/apache-tomcat-6.0.18-src
Using CATALINA_HOME: /etc/apache-tomcat-6.0.18-src
Using CATALINA_TMPDIR: /etc/apache-tomcat-6.0.18-src/temp
Using JRE_HOME: /usr/java/jdk1.6.0_11

makes me think tomcat has been installed correctly.

But when I try accessing http://localhost:8080/

Unable to connect

Firefox can't establish a connection to the server at localhost:8080.
* The site could be temporarily unavailable or too busy. Try again in a few
moments.

* If you are unable to load any pages, check your computer's network
connection.

* If your computer or network is protected by a firewall or proxy, make sure
that Firefox is permitted to access the Web.

Can anyone tell me how to solve this problem?

Hi,

first you should check if there is something running on Port 8080

Code:

netstat -an | grep 8080

Does the tomcat logfile show errors? It can be found in tomcat installation directory, sub directory log and is called catalina.out.

Thanks for the reply.

netstat -an | grep 8080 returned no results.

and following is the contents of catalina.out

/etc/apache-tomcat-6.0.18-src/bin/catalina.sh: line 292: /usr/java/jdk1.6.0_11/bin/java: No such file or directory

I suppose this is the problem.
my JAVA_HOME is usr/java/j2sdk1.4.2_03/bin/java

What should I do now?

Hi,

i agree. Your tomcat is looking for JDK 1.6.0.11 which seems not to exist. Check the startup script and install correct jdk.

I installed jdk1.6.0_11 and now the problem is

But when I try http://localhost:8080/

Though the site seems valid, the browser was unable to establish a connection.

Could the site be temporarily unavailable? Try again later.
Are you unable to browse other sites? Check the computer's network connection.
Is your computer or network protected by a firewall or proxy? Incorrect settings can interfere with Web browsing.

What now??

Your issue is that tomcat does not even startup or run, since you do not see any listeners when you searched for port 8080:

#netstat -an | grep 8080

The reason your tomcat is not running is that you are attempting the startup script from the source folder as opposed to the *built* folder.

Set the CATALINA_HOME and _BASE to
/var/lib/apache-tomcat-6.0.18-src/output/build/
And run the file ./bin/startup.sh

You should be fine then
