Hi Everyone I was working with Tomcat a year ago. It worked well then. When I double clicked "startup.bat" today it comes upto here Starting Service-Tomcat Stand Alone Tomcat/4.1 Then with so many errors which I could not even see ,the screen disappears. when I type "http://localhost" I am getting a page like this ORACLE HTTP SERVER COMPONENTS Apache Jserv .... etc. I am not able to access any files with the link "http://localhost/servlet/Hello.html" (which are in the root directory) Can anybody please help me ? Thanks Metelda

�t seems that there is a different web server running on your machine. Are you starting tomcat on port 80 ? And check your log for the first exception. This is normally named the root cause. There you will find detailed information whats wrong with your tomcat.

Hi Oliver Thanks for your reply. when I say "http://localhost" or "http://localhost:80" or "http://127.0.0.1" it is giving the same web page. Can you please tell me what is meant by "checking the log "? Where do I have to check ? Thanks Mary

Your Tomcat installation writes log files in the logs subdirectory Don't doubleclick the startup.bat - execute it from a command window so the window won't disappear and you can see error messages. Bill
Hi Bill Thanks for your reply. When I run from command line (i.e. startup) 'it just opens another window still disappears'. when I shutdown I am getting these errors. Catalina.stop:java.net.ConnectException:connection refused:connect at java.net.PlainSocketImpl.SocketConnect(Native Method) .... doConnect(....) ..... connect(.... like this . I just don't know what to do. Can anybody help me ? Thanks Metelda
The disappearing window usually means that you are trying to start Tomcat when it is already started, or when something *else* is using the port Tomcat expects to be able to use.
would give you Tomcat... except it doesn't, it gives you some Oracle page. This is the problem. Oracle is using port 80, and when you try to start Tomcat, it fails.

Hi Mike Can you please tell me which other port than "80" do I have to use ?? As you said "http://localhost:8080" is not working. Thanks for your response. Metelda
What XYZ is, is entirely up to you. I'd use something that is easy for you to remember, as you'll have to type it in, every time you want to access Tomcat.

Hi Mike Thanks very much for your response. I changed that line from "port=80" to "port=8010" (port=10 even ). But it did not work. Can you please tell me if I have done correctly. Metelda

To find out whats going wrong you probably need to see the output in the window that closes too fast to see You can do this by changing the startup.bat file so that it continues in the open command window instead of opening a new one. In the line that reads:
change "start" to "run" and the window will stay open. Also, we need to know which operating system you have and which Java SDK.

Hi Bill I changed "start" to "run". Tomcat is working now. It is using port"8010". I am really happy now. Thanks you Bill and Thank you Mike for your help. Metelda

<!-- Defines a cluster for this node, By defining this element, means that every manager will be changed. So when running a cluster, only make sure that you have webapps in there that need to be clustered and remove the other ones. A cluster has the following parameters:
className = the fully qualified name of the cluster class
name = a descriptive name for your cluster, can be anything
debug = the debug level, higher means more output
mcastAddr = the multicast address, has to be the same for all the nodes
mcastPort = the multicast port, has to be the same for all the nodes
mcastBindAddr = bind the multicast socket to a specific address
mcastTTL = the multicast TTL if you want to limit your broadcast
mcastSoTimeout = the multicast readtimeout
mcastFrequency = the number of milliseconds in between sending a "I'm alive" heartbeat
mcastDropTime = the number a milliseconds before a node is considered "dead" if no heartbeat is received
tcpThreadCount = the number of threads to handle incoming replication requests, optimal would be the same amount of threads as nodes
tcpListenAddress = the listen address (bind address) for TCP cluster request on this host, in case of multiple ethernet cards. auto means that address becomes InetAddress.getLocalHost().getHostAddress()
tcpListenPort = the tcp listen port
tcpSelectorTimeout = the timeout (ms) for the Selector.select() method in case the OS has a wakup bug in java.nio. Set to 0 for no timeout
printToScreen = true means that managers will also print to std.out
expireSessionsOnShutdown = true means that
useDirtyFlag = true means that we only replicate a session after setAttribute,removeAttribute has been called. false means to replicate the session after each request. false means that replication would work for the following piece of code: <% HashMap map = (HashMap)session.getAttribute("map"); map.put("key","value"); %> replicationMode = can be either 'pooled', 'synchronous' or 'asynchronous'. * Pooled means that the replication happens using several sockets in a synchronous way. Ie, the data gets replicated, then the request return. This is the same as the 'synchronous' setting except it uses a pool of sockets, hence it is multithreaded. This is the fastest and safest configuration. To use this, also increase the nr of tcp threads that you have dealing with replication. * Synchronous means that the thread that executes the request, is also the thread the replicates the data to the other nodes, and will not return until all nodes have received the information. * Asynchronous means that there is a specific 'sender' thread for each cluster node, so the request thread will queue the replication request into a "smart" queue, and then return to the client. The "smart" queue is a queue where when a session is added to the queue, and the same session already exists in the queue from a previous request, that session will be replaced in the queue instead of replicating two requests. This almost never happens, unless there is a large network delay. --> <!-- When configuring for clustering, you also add in a valve to catch all the requests coming in, at the end of the request, the session may or may not be replicated. A session is replicated if and only if all the conditions are met: 1. useDirtyFlag is true or setAttribute or removeAttribute has been called AND 2. a session exists (has been created) 3. the request is not trapped by the "filter" attribute
The filter attribute is to filter out requests that could not modify the session, hence we don't replicate the session after the end of this request. The filter is negative, ie, anything you put in the filter, you mean to filter out, ie, no replication will be done on requests that match one of the filters. The filter attribute is delimited by ;, so you can't escape out ; even if you wanted to.
filter=".*\.gif;.*\.js;" means that we will not replicate the session after requests with the URI ending with .gif and .js are intercepted.
The deployer element can be used to deploy apps cluster wide. Currently the deployment only deploys/undeploys to working members in the cluster so no WARs are copied upons startup of a broken node. The deployer watches a directory (watchDir) for WAR files when watchEnabled="true" When a new war file is added the war gets deployed to the local instance, and then deployed to the other instances in the cluster. When a war file is deleted from the watchDir the war is undeployed locally and cluster wide -->
