在Linux上部署Java程序

Question

A web application has been developed in C# which hits my Java code through a restful web service which returns a JSON response.This process was working on a local machine with tomcat server. Now my Java application needs to be hosted on an external server in Linux environment.

Using putty, I logged into the particular hostname and as a root admin. I have installed Java JDK 1.7, Apache tomcat server 7, my Java application as a war file is placed in the webapps folder. I can start the tomcat server too.

My question is:

1. How do I hit my application from windows. Is it http://xyzk:8080//MYAPPNAME(war file name)/ ?

2. How do i check the java logs in the linux env?

3. Also I have a set of files that I read from my windows folders as in C://uploads//file.txt or C:\\DeveloperTool\\Pluggins\\

I replaced them with the linux structure in my java code. as /home/opt/file.txt Will this work?

How do I hit my application from windows. Is it http://xyzk:8080//MYAPPNAME(war file name)/?

If 8080 is the port Tomcat is configured to listen on (I think by default, it is), then that is correct. Bare in mind the web app name is case sensitive. You can configure this setting in $TOMCAT_HOME/conf/server.xml

How do i check the java logs in the linux env?

Since you're using a remote shell over SSH, you will want to use either tail or less to monitor logs in real time. The log files are stored in $TOMCAT_HOME/logs.

Try

$ less +F /path/to/tomcat/logs/catalina.out

catalina.out is the main file when running Tomcat on *nix systems.

Also I have a set of files that I read from my windows folders as in C://uploads//file.txt or C:\\DeveloperTool\\Pluggins\\

I replaced them with the linux structure in my java code. as /home/opt/file.txt Will this work?

As Lutz Horn mentioned in the comments, try it. In theory, that should work fine as long as the permissions are setup properly.
