Is Tomcat still the reference implementation for Servlets and JSP?
Hi all, Does anyone know if Tomcat is still the reference implementation for Servlets and JSP? I thought the Servlets 2.5 spec was finalized in May. Why is it taking so long for a release version of Tomcat that implements Servlets 2.5? Also, I don't understand how Glassfish can support the new specs when it embeds Tomcat.

System path being ignored when using Tomcat Windows service?
Hi all, I have a web application that uses Runtime.exec() to start a process. The process that I'm starting is in the system path. The application works fine if I'm running the Tomcat platform independent package. However, if I use the Tomcat Windows service, it appears that the process can't be created because it can't be found. It works if I specify the fully qualified path the the executable, but, I want to use only a relative path. I'm wondering if the fact that it appears to be ignoring the system path has to do with the fact that it's a Windows service, or, if it's an issue with Tomcat? I'm running Tomcat 5.5.20 with Sun JDK 1.5.0_10 and Windows XP SP2. Also, I noticed that if I change the user account that the Tomcat service is supposed to run as using the system tray applet, it doesn't change the settings, it just keep reverting back to LocalSystem. Has anyone else ran into either of these issues. As far as I can tell, the second issue looks like a bug. Also, I tried setting java.library.path using the applet, but, that didn't seem to help.

Re: System path being ignored when using Tomcat Windows service?
I think it must have been a permissions problem. I switched to using a different account and now it works. The systray applet doesn't work. I had to change it using the normal Services application that's built into Windows.

Re: Memory leaks on webapp redeploy
I'm getting ready to try NetBeans profiler right now. I tried it awhile back before it was released, but, there was something wrong with the Solaris library, so, I couldn't get it to work. I'm hoping I'll have better luck now that it's been released officially.

Re: Memory leaks on webapp redeploy
Thanks for the info Remy. I've been using Sun's JVM, but, I think I'm going to try IBM's to see if that makes a difference.

I've been having a lot of problems with this. I think what's exacerbating the problem is that I'm using Hibernate and JAX-WS which I have bundled with my application which use a lot of memory. Yes, we experience same problems with Tomcat 5.5.17 We did a lot of tests and profiling instrumentations (Jprofiler powered) on many environments : Win32/Linux, JDK1.4.2_12, JDL 1.5, Tomcat 5.5.17/5.5.20 Same problem: many redeployments (or reload) of a webapp throw an OutOfMemory for the PermGenspace. If you monitor your Jvm with Jvmstat tools you would see this non-heap memory never been released... The problems seems to be located with Cglib classloaders referencing policy. There is a lot of topic on the Net, which may be interessing to read, but noone seems to have found a valuable solution. (Increasing the PermGenspace is NOT a reasonable solution) The only way we found to fix it is to change the JVM. Indeed if we use the BEA Jrockit 1.4 JVM, the application can be deployed as many times you want...

Re: JSP alternative to ASP.NET
JavaServer Faces is basically the Java equivalent of ASP.NET. JSF lags sufficiently behind ASP.NET IMHO though.

I tried it awhile back before it was released, but, there was something wrong with the Solaris library, so, I couldn't get it to work. I'm hoping I'll have better luck now that it's been released officially. I downloaded the Linux version of JProbe's profiler, and I can't figure out how to start it. The only binary that makes any sense is jpprofiler, and that gives me a DISPLAY is inaccessible error, even though I can run xterm and xclock and stuff no problem. :( Let me know how it goes with the NetBeans profiler. Also, let me know if it was easy to get going. I'd love to use something that I can attach to a running process -- sorta like Sun's jconsole. I'm not sure I would recommend NetBeans profiler. I ran into a few different issues. It's pretty easy to install and the interface seems pretty intuitive. I was able to kind of get it to work running NetBeans on a Windows XP system (1.5Ghz Pentium IV) and remotely debugging Tomcat on a Solaris system. However, I received some errors in the log about it not being able to load some class files. It looked like it might have had to do with classes that were generated dynamically (probably Hibernate proxies). For some reason, I couldn't find my applications classes. I could see Hibernate and JAX-WS related classes, but, mine weren't there. Then, it locked up. It did that twice. Then, I switched to trying to profile it on a local installation of Tomcat. I found that it kind of worked albeit extremely slowly if I selected the Analyze Memory Usage option and only Record object creation only. If I tried Record both object creation and garbage collection or Record Stack Trace for Allocations options, it ran so slow that my mouse cursor wouldn't even move. I think what I may end up having to do is simply restart Tomcat everytime I do a redeploy. Strange how I haven't run into these issues with the ASP.NET apps that I've developed. Also strange how a problem like this could go on for YEARS without being fixed.
