Re: Yoav --RE: TC 5 production use
Also keep in mind that Apache isn't the *only* thing you can put in front of Tomcat. grin While we do have Apache in the mix (for some legacy apps), we also run Squid [1] in reverse-proxy mode in front of *that* to (a) reduce response time on cachable content and (b) remove some of the load on Tomcat. It did mean we had to be pretty careful about our HTTP cache-control headers, but it's been a nice solution. dwh [1] http://www.squid-cache.org/ Shapira, Yoav wrote: This is a good example of something that hits on Apache's strong points: perl, mod_php, rewriting.

In many of those cases, Apache is not needed.

Re: localhost vs IP address in the URL
I'm not a networking guru, (and this is sort of OT for Tomcat) but I'm not convinced by M.Schwartz's response that this is due solely to DNS name resolution. I don't think that would account for such a big difference in time--once the name was resolved to the IP address, behavior should be the same, no? Saravanan, you say there's a 20x difference but what's the magnitude? Are we talking 10 ms vs. 200 ms. or 1 second vs 20 seconds? By IP address do you mean 127.0.0.1 or the IP address of the computer? My pet theory is that the TCP/IP stack is recognizing the IP address as being of the local box and is shortcutting packets from transmit queues to receive queues in memory, without actually getting the NIC involved or anything. Or maybe the NIC is doing this. Many years ago when I did hardware testing, we first ran into TCP/IP stacks that had this optimization. The other thought is that for some reason different maximum packet sizes are being used with these different connections? Of course, this is just a theory. Someone with a little more knowledge might be able to speak more authoritatively grin. dwh Saravanan Bellan wrote: Windows 2000 Tomcat 3.2.3 If I try to upload a file using the regular HTML/HTTP, there is a 20x difference in performance between using localhost vs the IP address in the Web Server URL.

Re: version question
Sounds premature to blame Tomcat (or that version) for this.

Does the JVM exit? If not, what's the behavior? Error responses? Hung responses? - if responses are hanging, I would get a thread dump and expect to see one or more threads deadlocked. - does it happen in a single-client test, or only when multiple clients are accessing (again, that would indicate a threading problem) - is this something that worked satisfactorily with earlier versions of infrastructure and is only now breaking?

Re: Crystal report work with Tomcat
Hi We use CR within Tomcat, but we do NOT use the java API for the report display applet. We actually create downloadable reports with various formats (PDF, RTF, etc.), and do not display them. So the following may not apply to you. If your goal is only to show reports using their applet, my guess is that you should be able to copy their JAR file(s) to your WEB-INF/lib and use the Java API for the report applet. For what we wanted to do, I had to actually write a few DLLs, since CR does not provide any entry in its API that is java-based and that is aimed to something else than displaying a report in an applet. So here's the solution we have : -- Report templates and logic are stored within a Visual-Basic DLL (CR integration with C++ is a real pain) as DSR objects from CR dev components. -- This DLL is loaded and accessed through JNI, but as JNI is C/C++ based, we needed a C++ DLL that actually forwards all requests to the VB DLL... -- The JNI DLL is loaded within Java using loadLibrary and a Java class defines all the native methods accessible via JNI.. The VB dll is placed in the WEB-INF/lib folder and the jni access DLL is placed in the JDK/bin directory. Now the drawbacks : It is complicated for no apparent reason (the only reason is that CR does not provide any java entry point...), because there's 3 layers of code (java class declaring native calls, JNI DLL, VB DLL) It is a real pain trying to support multiple formats as CR 8.5 has an incredible amount of bugs (PDF needs several patches). It is a real pain to install the CR 8.5 dev components on the machine where Tomcat runs because there's many patches to apply in a definite order. It is not stable at all...it crashes every 2 or 3 days or so, but I cannot blame CR for that because I haven't took the time to make sure it's not my code that leaks memory...(although MSVC++ dumps do not show any leak) and that JVM crashes I experience are not caused by my JNI calls. And the worst is, despite what CR engineers said (until I sent them some code proving the point), the export DLL they provide is not multi-threadedwhich is a nightmare in a web-environment because every creation of a report is queued...

Re: Tomcat 3.2.2 HTTP 500 Internal Server Error
Unless you are willing to spend a little bit of time reconfiguring Tomcat, and maybe modify your install scripts, you can stick to Tomcat 3.2.x (currently 3.2.4).

Me and include directives....
Hi all I already have asked for some directions on how to use the include action and the include directive and had very nice answers... but I might have burned too much neurons on that and I'm still missing some point... ...and...I experience some unexpected behaviour using the %@ include file=blah.jsp % The quick ref on JSP I have (http://java.sun.com/products/jsp/pdf/card12.pdf) tells me that include uses a relative URL as the file parameter.

Re: Help : Use Oracle 8i JDBC driver
Aside from the fact that my ears are ringing because you're shouting, I do not agree with the recommendations you provide... Moreover, the question was aimed to Tomcat 3.2.3 Crippling the CLASSPATH with custom entries, as well as filling the JRE/lib/ext directory does not sounds like a good idea. It does not help when it is time to write install scripts and gather all the librairies you are using to bundle an application, or a web-application, and to deploy it. The JDBC drivers, as all Jar files you are using (remember that ZIP files can be renamed to JAR ! and you need to do this), should definitely sit in the WEB-INF/lib directory, unless you want to share it among all web-apps, in which case, the best place is probably TOMCAT_HOME/lib. Tomcat 4.x has a better model for handling Jars and stuff, but as we're dealing with Tomca 3.2.x, that's probably how you should do it You can customize Tomcat 3.2.x startup scripts and modify the internal classpath, but you should avoid setting anything in your environment variable Anyway, check the archives, this topic has already been discussed a lot I think Cheers Denis - Original Message - From: Siomara Pantarotto [EMAIL PROTECTED] To: [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: Tuesday, December 04, 2001 12:17 PM Subject: Re: Help : Use Oracle 8i JDBC driver --- Mike [EMAIL PROTECTED] wrote: Hi everyone.

Re: Known Memory clean-up issues?
Hi all Where would you recommend to use System.gc() in the context of JSP pages ? I guess it would be useless to intercept every single request and hint the system for garbage collection on each request ? (Now I quote) Also, before an OutOfMemory is thrown, the Garbage collector is guarenteed to run, meaning that you really are using all of your memory. I would look at what you are doing in your code - I have servlets that run for weeks without eating up any significant portion of memory I do have many times OutOfMemory exceptions thrown, although we're not doing *that* much It happens quite randomly so it's very difficult to isolate the problem. Moreover, it even happens when fetching HTML pages from Tomcat, without using much JSP... I'd like to find a place to catch that error to take action (like restarting Tomcat) but the only way we have found is to monitor the server and automatically restart it when it fails to respond.

If you have only one web-app that references this driver, you should put it in WEB-INF/lib. This allows for better maintenance and management of your libraries and dependencies. To reference/load the driver classname, you could use a parameter entry in the web.xml file... You could even have a startup servlet to load the driver in DriverManager and/or have it available through some lookup system such as a JNDI service.

Re: Where to put .properties so web app finds it
We use property files to configure our framework when it gets loaded by Tomcat through the WAR files. The most convenient place we've found for those files is under WEB-INF/classes as it is the root of the classpath of your WAR app and you can retrieve your file using ClassLoader.getResource(property.properties) without having to parse or create any URL or the like... So, it seems a convenient place to do so. You could as well have an entry in web.xml telling your framework where the property files are located, but you will have to find a mean to retrieve this setting. It is not so good if your framework is not servlet-oriented (in this case, you don't have direct access to ServletConfig, where the setting will be located). You can also use a -D on the Tomcat command line (by using TOMCAT_OPTS in Tomcat's startup scripts) but this is the worst scenario as you have to modify a file that does belong to Tomcat and not to your App. Hope this helps.

(Assuming that you have access to the source code of your servlet classes, of course.) I would set -Xmx as high as reasonable for your physical memory configuration. And definitely use -server. Other than that, IMHO you're going to get a *lot* more improvement by focusing on your code, and many JVM command-line parameters will in fact hurt performance unless you really know what you're doing. What problems are you encountering? Is your servlet just slow, or does it run out of memory? If the former, you really need to get one of the optimizing tools available (several have free evaluation periods) or you can use -Xrunhprof and crawl through the profiler output yourself (I'm getting very good at that grin). If it runs out of memory, same approach, actually. Either a profiling tool or -Xrunhprof will let you identify where your memory consumption is going. We have a servlet application that was running out of memory, which we addressed by using soft references to let the GC reclaim objects that we were willing to recreate if necessary.

Re: Q: How to use mod_rewrite with mod_jk?
Hmm. Works fine for us (Tomcat 3.2.x, Apache 1.3.19, Solaris, jdk 1.3.1). Given that you're tried the ordering of the AddModule lines (don't know if LoadModule needs to be in order too--wouldn't think so) and you have the PT flag, I guess I would recommend turning mod_rewrite logging up to full and make sure that the final rewritten URL from mod_rewrite is what you expect it to be. Actually, now that I read your message more closely, I'm not sure I understand the problem. It sounds like the requests *are* getting to Tomcat but they aren't in the form you expect when they get there? Or are the requests not getting to Tomcat at all? Perhaps some examples and some RewriteRule snippets would help. dwh amduser amduser wrote: Q: How to use mod_rewrite with mod_jk?

Using the PT flag on rewrite rules doesn't help either. The same rewrite rules work perfectly with Caucho Resin's mod_caucho.

You're 'locked in' to the structure you describe only if you use the default webapp context. Instead, create your own context(s).

Re: Internal Server Error on first couple requests
What exactly do you mean by 'startup'? If you're using ajp, you must start Apache and Tomcat together, because of the persistent connections. That is, if you shut down Tomcat, you have to shut down Apache also, and vice-versa. This is documented... Or do you mean to say that when you start both of them up like this, you get Internal Server Errors on the first few requests? If so, does it matter how long after startup you try this? I certainly find if I try to access Apache/Tomcat before Tomcat has finished loading, I can sometimes get that error. dwh Mike Tinnes wrote: We're using Tomcat 3.2.2 with Apache 1.3.20 and are experiencing problems with jsp's not loading correctly on startup.

Re: [MOD_REWRITE] Why...
We found that we had to do 2 things: 1) Make sure that mod_jk was loaded into Apache *before* mod_rewrite, which meant moving the loading of mod_jk from mod_jk.conf to Apache's httpd.conf, and we listed it in the LoadModule and AddModule lists *before* mod_rewrite. That ensured that mod_rewrite got to the URL before mod_jk did. I'm now less convinced this is absolutely necessary--the next item may be more important. 2) Put the [PT] (passthrough) flag on all RewriteRule lines that were rewriting URLs to go to Tomcat. Also, one gotcha we hit was using the same pathname for both the incoming URLs and for the Tomcat context, e.g. http://ourhost/ContestSignup for the URL and /ContestSignup for the context path. It's better (maybe required) to use a different name for the context path, like /ContestSignupServlet. dwh Francis Pallini wrote: Hi, It sounds like you are a little sarcastic ;=) Regards, Francis Pallini At 11:25 AM 8/9/01 +0200, you wrote: Can anyone tell me why the when using the mod_rewrite module, Tomcat can't/don't seem to retrieve the rewritten url and args?
