Re: Configure mulitple installs tomcat 8.5 - catalina_base/catalina_home
Thank you so much for replying. I actually found the issue and it was simple. The starter daemon (which I don't control, unfortunately) wasn't launching the tomcat installs from the proper locations. It was calling the respongindPROD startup.sh from the initiatingPROD dir every time, no matter which tomcat installation it was launching. Fixing that fixed my issue completely. Thank you, Jason T.

All that looks weird. If startup.sh shows CATALINA_BASE == CATALINA_HOME and both initiatingPROD and respondingPROD have separate values, then then nothing should be interfering. Honestly, if you expect to run them on the same version of Tomcat (oor eve if you don't!)

Re: is too quick to respond
John, On 2/23/22 05:49, John Barrow wrote: Christopher, You will just change the implementation to answer the question "have any resources been modified, but not-too-recently?" OK The check must be fast, otherwise it will hang-up other processes on the server. Don't introduce any new loops or stalls. Just return true or false as quickly as possible. The process will be repeated during the "next" check so you only have to decide not to reload "too early"? Not sure that I understand this point (re 'check must be fast'). I wasn't imagining affecting the initial trigger point at all (i.e. Tomcat has detected a change in one of the active files) so shouldn't affect the day-to-day performance. Once Tomcat has decided that a reload is required *and* the user has requested for Tomcat to do the reload (i.e. Context flag is defined to true), prior to actioning the reload, add the additional check (simple user-specified timer delay to allow the external application time to finish deployment, and then let Netbeans carry on. Tomcat won't even check for any changes unless . Tomcat has a background thread that does all the "backgroundy things" that need to be done. This is one of those things. If you hold-up that thread, than you hold-up everything. That's why you can't just stall for 10 seconds and then proceed. Instead, you say "sorry, file is too new; don't signal to reload (yet)." You don't want to hold-up the reload process itself, either, for a bunch of reasons. First, it's not really appropriate because "reload now" means "reload now" not "reload when you sort of feel like it." Your additional suggestion that the time-stamps of the amended files should remain consistent over that period also sounds sensible. Given that Tomcat can't implement the event model for reasons you have already explained, I am now thinking that the event that triggers the re-build won't contain details of what files have been amended, simply that there has been a change. Yes. Snapshotting all the files within the two folders, noting the timestamps and then polling again after the delay seems to be repeating what Tomcat is probably already doing to trigger the event in the first place. Exactly. You don't need to do any of that. Now that I just about have a development environment I can explore and debug, I think I should spend some time around this class and learn when / why it's called and the calls it makes to do the reload. So far, I have had to imagine how the code is structured and so consider a solution based on that (possibly false hypothesis). Well, even if the unit tests won't pass within Netbeans, I'm assuming that the built-in text editor is working. Just go to the code Mark initially suggested and start reading. I think it will significantly inform this conversation. Just to be clear from other questions, I have no intention in going anywhere near the 'rebuild' process - that is a black box as far as I am concerned. Good. The only process you need to tweak is the one that decides if the context *should* be reloaded. That's a relatively straightforwar process, currently, and you are going to make is slightly more complicated. -chris - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

We can drop the issues over JSP as the NetBeans community has taken up that baton. > That is an abstract base class. You won't be able to run it. Trust me to pick that one! I have only ever written simple unit tests so not needed to create any abstract classes in my testing, but I should have spent more time looking into your source and then would have spotted the 'abstract' keyword!! In a very weak defence, I tend to use interfaces rather than abstract classes. Anyway, thanks for the naming conventions, that will prove time-saving. For good measure, I ran TestDefaultServlet and that ran the tests successfully.

I also added it to the since, as the project references files inside this folder, it seemed applicable to include it. However, it didn't appear to make any difference - i.e. NetBeans still couldn't tie the source back to those Java classes. I have checked that I have typed the paths correctly and I can see the trailers.ResponseTrailers (& util.CookieFilter) file(s) in the WEB-APP\classes and visible in the project folders (I assume as added to ) to back-up paths are valid. NetBeans doesn't let me take any action to try and find the file to resolve the [!], I assume because it is a free form Ant project and so configuration is 'read-only' once loaded (I would have options in Maven to locate the missing resource). I have added my current project.xml and Trailers.ResponseTrailers.jpg to the DropBox folder in case either of them helps. My only observation is that, as I can't find a corresponding XSD file for project.xml, there is another attribute I need to set to indicate that these are class files in a different folder to the one the other package files are in, but that seems unlikely. > I think you mean 8000 for remote debugging but otherwise great.

I had amended the catalina.bat line "set JPDA_ADDRESS=localhost:8080, because I connect to Tomcat using http://localhost:8080/examples. Your statement concerned me slightly in that I now believe that I had made a wrong assumption. Anyway, I amended the catalina.bat back and set NetBeans remote debugging to the same and it worked as well so I will leave it at 8000. I couldn't find anything on the web re Port 8000 vs 8080 (apart from "use which one you want"), but I suspect that, ideally, the debugging communications should be using a different port to the application otherwise there may be conflicts but couldn't find anything to back up that hypothesis. > - Patch file in diff -u format attached to a BugZilla issue > - GitHub pull request > Happy to provide pointers for either approval if needed. Unfortunately,II will now probably have to wait a bit for that. I will soak the changes to the NetBeans configuration files while I explore Tomcat, once the webapps/examples/WEB-INF/classes issue is sorted and (hopefully) the NetBeans community has resolved the other exceptions. That way, if I discover another missing link, I can incorporate it and upload all the configuration changes at once to minimise confusion. However, I am away in a weeks time - 5th March (Snowboarding at last!), and have to catch up with some other chores / tasks before getting back on the laptop. Hopefully, we can get these last minor
Re: In what directory was tomcat installed

Tomcat 8.5.75 Servlet WriteListener and ReadListener setting thread
Hello! I have an application where a ReadListener and a WriteListener (call it MyWriteListener) set to the ServletInputStream and the ServletOutputStream objects. Updating the Tomcat container from 8.5.73 to 8.5.75, the follow error occured. The ServletOutputStream objects's isReady function always returns false (within MyWriteListener.onWritePossible). I think its because of this commit: https://github.com/apache/tomcat/commit/2bfbbef65d1b1b07da46c8dcd6cee96cb5567998#diff-1ffbc1c154370a6c5385c168a0846a1c385aacbf5f880feb74cb1c27baa76003 The ReadListener is set first, where dispatch fired (action(ActionCode.DISPATCH_EXECUTE, null);). There the request threadId updated (req.setRequestThread();). Then when i'm setting the WriteListener (within the same thread), the DISPACTH_EXECUTE action not fired (due to threadId equals request objects thread id). Thus registeredForWrite flag remains is true state, causing the isReady false behaviour. Is this a Tomcat bug, or I should do something differently. I could't set WriteListener within a different thread, but it feels weird. Should i do something else? Thank You in Advance, Istvan
