Re: (newbie) Why tomcat needs network on startup?
It doesn't need network connectivity (at least not as far as i know). Most developers use it within a localhost setting. If you're on windows and you're getting a prompt about a process wanting to open a port, that is just a network security issue, it doesn't mean tomcat requires internet access.

Re: creating user url...
You can create directories using the java.io package. Unless you're going to store a lot of per company info like images and such, using the getPathInfo is the better solution. Even if you want to store per company data, you can store all such files in one directory with ids stored in a database. So for instance if you want to store logo.png for each company, you'll have a directory called logo and a database table called logo with company id as a key and logo id as another column. Then you can use the logo id as part of the file name. On 3/17/07, kace [EMAIL PROTECTED] wrote: thanks Edmond, ill google for getPathInfo(). Can the directory for each company be created on the fly?

Re: creating user url...
I have never implemented such a solution but I know a lot of sites have similar setup. There are two ways you could do it, one would be to create a directory for each company and then drop an index.jsp file in there . A second and perhaps better solution would be to get the path info of the request from javax.servlet.http.HttpServletRequest.getPathInfo(). so in essence whenever a request comes to your servlet, getPathInfo would extract the part that has the company name. Google to get further info.

if you're trying to access tomcat running on your pc via the internet you'll need to open ports on your router.

Re: DWR using WAN vs LAN
You may want to limit your question to one topic at a time. I've read through your post and it is difficult to tell what your real problem is. The networking issue, I assume you've already been informed, doesn't belong to the mailing list. Tomcat/Apache/PHP can all work together depending on how you send up your application. Apache's mod_jk is how you make Apache and tomcat work together. If you create an app that uses both Tomcat(jsp) and PHP then you'll have to manage two separate sessions, though that shouldn't be terribly difficult to do. Tomcat is configured to run on 8080 by default you can change that to 80 by editing the server.xml file. All http traffic that doesn't specify a port automatically go to 80. To access your computer from the Internet you'll need to first open the port on your router or remove the computer you want to access from the router's DMZ (not recommended). Make sure you use your actual IP which you can determine by typing what's my IP on google and following the first link. Hope this helps.

I know some of these questions are borderline inappropriate for this mailing-list subject but they, at least loosely, apply. My newbism is defiantly showing. First, the idiot I am I didn't realize port 80 was 80 and 8080 was 8080. I thought they somehow referred to the same port, du! That explains allot of my confusion! With that said What happens if you try http://wan-ip:8080/chat-demo? Without the port number, you're sending the URL to something other than Tomcat that's listening on port 80. this is where the confusion starts. Your telling me to send the URL to http://wan-ip:8080/chat-demo; but then you say you're sending the URL to something other than Tomcat that's listening on port 80 Here I go getting confused again, what is it 80 or 8080? Or was that just a slip on your part? I'm going to assume the latter unless you tell me otherwise. Either way, I get page not found if I use anything other than http://localhost:8080/chat-demo which works perfectly or I can get to it at least run the page with http://wan-ip/chat-demo because I have an Alias /chat-demo in Apache config serving on port 80, but that's when I get the Chat is not defined error. I though maybe my provider was blocking port 8080 so I even tried http://localhost:7077/chat-demo which my router is redirecting to 8080. That is what I have to do for Apache and that's what I was talking about when I said A couple of things worth noting. I'm pretty sure my (cable) access provider is blocking 80 so I am forwarding ext. 7075 ext. = web browser pointing to port 7075 and to int. 80 with Apache still running on 80. int = router redirect to port 80. I was referring to my router redirecting port 7075 to port 80. So if I am understanding this correctly I am not getting through to the Tomcat server from the WAN. I also can't get through to Tomcat using http://computer-name:8080/ I can only get through using localhost:8080. I checked XP firewall and have 7077 port (redirected to 8080) opened. Any idea why I cant get to it? script type='text/javascript' src='/chat-demo/dwr/engine.js'/script script type='text/javascript' src='/chat-demo/dwr/interface/Chat.js'/script script type='text/javascript' src='/chat-demo/dwr/util.js'/script Also, where are these files? They're part of the app, nothing to do with Tomcat itself. I realize that they are part of the app. This question was because I though maybe something to do with the paths to them was causing the error. That's because I am not to familiar (yet) with the file/directory structure regarding Tomcat apps directory and was able to find script type='text/javascript' src='/chat-demo/dwr/engine.js'/script script type='text/javascript' src='/chat-demo/dwr/util.js'/script but not script type='text/javascript' src='/chat-demo/dwr/interface/Chat.js'/script which is why I said If they are in the dwr.jar file then I am beginning to understand the organization except the src='/chat-demo/dwr/interface/Chat.js' file isn't in that jar. If it is in the chat.class file then I think I am really beginning to understand the organization. If this is correct then it still leads me back to I'm not getting through to Tomcat from WAN or for some reason using my computer-name either. My Configuration: Windows XP Pro devside.net Web[Developer] Server Suite 1.94 standard installation ASP,MYSQL,PHP (not cgi) and Tomcat5 All are working correctly. If that were really true, would you be asking questions here? What I meant is they are all working correctly independently so to speak. They may even be working perfectly but not configured correctly to allow PHP, MySQL, ASP and Java to work on the same page at the same time which is what I am ultimately trying to accomplish. Is it your router doing the forwarding? If so, external users will need to append :7075 to the host name or IP

Re: shut out IP-adresses / subnets
You can implement a filter to check all request to your app before processing. But if you don't want an IP address to access your app then I assume you don't want that IP address accessing anything on the OS you're running.

Re: How to forcibly close abandoned database connections?
It is possible that whatever procedure is responsible for checking for abandoned connections only does so when there is actual need for a connection, similar to how a garbage collector works to reclaim memory. If there is no seeming stress on the connection resources then it would make sense not to jump the gun to look for and recycle abandoned connections. Of course I don't know if that is what is happening, but I suspect it might be. On 1/10/07, David Uctaa [EMAIL PROTECTED] wrote: Perhaps I was unclear what it is I'm trying to do.

It is showing, let's say, that there are a max of 30 connections allowed, that 11 have been established, and 9 are busy. I know that these 9 are due to a connection pool leak bug that was corrected (but not yet deployed), so even though the application has gone idle and no one is using it, the connections remain busy indefinitely. I have enabled removeAbandoned in my server.xml, but according to the Tomcat docs, abandoned connections are only recycled if there is a need for them, due to the number of available datasources getting low. The number of available datasources are not yet low, so these orphaned connections are still being reported as busy. I'm a little bit anal with regard to keeping things kinda clean on the server, so I would like to have these abandoned connections no longer reported as busy once they are orphaned.

If your running fedora/redhat, it usually creates many symlinks and places the actual files into different folders. The only reason this is done I think is for flexibility.

Re: Moving Tomcat
If you have the second server setup then you can install tomcat and copy the webapps folder over and see what happens. Once you start getting errors from the new server then you can troubleshoot until everything is fixed. It will be difficult to know if everything will work without testing.

Not quite a tomcat question
Happy New Year All. Does anyone use sessions to temporarily hold confirmation codes for user registrations? I have a setup where when the user registers a random confirmation code is generated and appended to a url which is emailed to the user. The user's registration data is stored in a session with the confirmation code as the key. When they click the confirmation link, the code is used to retrieve the registration information and the registration is done. Some users are having trouble because it seems they're encountering invalidated sessions. I know if the registrations is done in one browser and the link (outlook will open IE) opens up a different browser that would lead to the creation of a different session which obviously wouldn't have the registration data. I have seen implementations that enter the confirmation directly into the database but I don't want to do that since it would mean writing more code to check who's account is activated and who's hasn't, and also might lead to garbage in the database of users who never activated their accounts...Any suggestions? -- talk trash and carry a small stick.

I ran into a similar problem in trying to serve static content with tomcat,
tomcat had trouble retrieving dynamically created content unless it was
already in the webapp at start, at least that was my experience. Since
you're trying to create a jsp, why don't you create one jsp and pass it your
preview data, then return that to the user. Even if tomcat could serve newly
created jsp, i don't see why you'll create a .jsp page every time the user
hits a preview button, one jsp should do. Also you may want to look into
autoDeploy etc.. config properties, there are options you can enable to make
tomcat notice changes in servlet code (including jsp), I am not sure they
apply to newly added JSPs.

Environment: Tomcat 5.5.17, Windows XP
Background: I have a jsp page that contains a javascript rich text editor
that I use to create snippets of HTML code that are stored in a database and
later displayed on other pages. Since the snippets can contain some custom
tags, I have a 'Preview' button that reads the snippet directly from the
editor, reads a 'preview' jsp file from the file system, places the snippet
in the correct place in the file, writes the 'preview' file with the snippet
to a temporary file and opens a new window (using javascript) which requests
the temporary page from Tomcat.
Problem: I can see the newly created temporary file in the file system.
I can open it with an editor and it is all good. But, Tomcat returns a 404
error for approximately one minute and then will serve the page upon hitting
only the refresh.
Analysis: I suspect the system is holding onto the newly written file
until it hits some timeout but I have tried everything I can think of to
make certain the file has been 'released'. The relevent parts of the copy
process:
try {
File tempFile = File.createTempFile(preview, .jsp, new
File(C:/projects/EtrakWebApp/web/jsp/tempfiles));
// read the preview jsp
FileWriter fw = new FileWriter(tempFile);
File infile = new File(destinationDir+preview.jsp);
if( infile.exists() )
{
FileReader fr = new FileReader(infile);
BufferedReader in = new BufferedReader(fr);
while(true)
{
String line = in.readLine();
if( line==null )
break;
System.out.println(line +line );
// insert the text
if( line.contains(insert_preview_text) )
{
fw.write(previewText+\n);
}
else {
fw.write(line+\n);
}
}
fr.close();
in.close();
}
fw.flush();
fw.close();
fw = null;
}
catch (FileNotFoundException fnf)
{
fnf.printStackTrace();
}
catch (Exception ex)
{
ex.printStackTrace();
}
return returnFileName;
Anyone have any ideas?

Re: jsp optimization for db driver load and connection
I doubt there is connection pooling when you use the driver directly. There is connection pulling if you use java...DataSource I think.

Re: forced to constantly restart Tomcat
Is there a reason you can't use something like netbeans? which comes bundled with tomcat, that way your don't have to fiddle with the settings.

Re: Web server hosting question using tomcat 5.5
Firstly you'll need to configure (open some ports) your router to allow direct access to the tomcat port on your machine. Assuming you know the IP address of your router ( type in google: what's my IP address), user should be able to connect to your app by typing something like http://YourRouter's IP:Tomcat Port/your context path..That should be it.

Re: Web server hosting question using tomcat 5.5
The 192.168... is an IP only valid behind your router, for someone on the internet to access your app, you'll need to use your router's Iternet IP address. Again you can determine that address by typing What's my IP address in google and then select any of the results. From the URL you stated, I don't see any reference to the context path of your app, tomcat from what I know isn't going to find an abitrary index.html, you must specify which app you're trying to access.

Re: Problems with tomcat session timeout on linux
You may want to look into SessionListener/Session event Listener. I am not sure what the issue is with regards to the timeout, setting timeout to 30 means the session should expire in 30 minutes.

Re: Problems with tomcat session timeout on linux
Well, I must admit, I run Ubuntu myself and I have noticed on a few occasions (after multiple netbeans builds) that the session doesn't get destroyed in a timely manner sometimes. So it is possible that there is an issue but it happens for me very rearly, I don't know whether this is an issue that happens on deployed apps. You can do some googling to see if anything comes up. Unless the user remaining logged in poses a security/resource problem, then you probably shouldn't stress over it, idle sessions do eventually get invalidated.

serving static html with Tomcat
Hi guys I am a newbee so bear with me.

Re: serving static html with Tomcat
Hi Christopher My directory structure is as follows: context_path/customer/public I make a call to my jsp via something to the effect: URL url = URL(jsp); write the stream i receive to context_path/customer/public/customer_id/index.html The servlet function from within which the above processing is done should return a preview of the page to the user via return (new ActionForward(/customer/public/cutomer_id/index.html)); I am using struts by the way. the returned actionforward results in 404 error. The html is also available on the main site for searching, when i click a link that results from the search I get the same 404 error. When i redeploy the app I can search and the 404 error doesn't happen when I click a result link.

Re: serving static html with Tomcat
I know premature optimization is root of some evil, but I prefer the setup I have at the moment, I think it will work fine. I beleive I will benefit performance wise if I don't have to do constant queries against my db, I am not sure how much performace gain there will be. As far as indexing with lucene, I am using a RAM index, which is updated whenever the user elects to republish content, the index is also stored on disk in xml form so that if the webapp has to be rebooted (which will happen invariably) it will be parsed and reindex into RAM.

If not, so don't waste your time with unneeded optimisations. Speaking about Lucene: it's a waste of its power to index html files generated from a database.
