RE: TC Apache integration
From: Paul Wallace [mailto:[EMAIL PROTECTED] Subject: RE: TC Apache integration Unless you are saying that TC 5.5 is as robust as Apache. I have difficulty conceiving of a situation where adding non-redundant componentry can improve robustness. I suppose it's theoretically possible, but, in general, adding complexity pretty much always degrades mean-time-to-failure. If that is the case, where does that leave httpd? Load balancing, routing, possibly a more familiar security configuration (not necessarily better, just better known), and of course, a fast basic web server. CGI and PHP should be more efficient with httpd - it all depends on what your predominant traffic is along with other site-specific requirements. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

RE: RAM limity
From: Nikola Milutinovic [mailto:[EMAIL PROTECTED] Subject: Re: RAM limity I'm using TC559 and JVM 1.5.x with Win2003 / 2GB RAM. I'd like upgrade to 4GB RAM...is there any JVM or Tomcat limit here? I think JVM cannot use more than 1.6 GB of RAM - dunno why. It's a Windows limitation. Windows normally provides only 2 GB of virtual address space per process, and this is somewhat fragmented by various DLLs that are scattered about in it. The JVM requires contiguous space for its heap (at least it did in 1.4, haven't looked inside 1.5 yet), and the biggest chunk it can get is about 1.6 MB. There is a bootstrap option (sorry, I can't remember the tag) for some versions of Windows server that allows 3 GB of address space per process, but it reduces the amount of memory available for kernel control structures, so there are tradeoffs in using it. Also, the 32-bit JVM did have a problem with heaps over 2 GB due to sign handling errors; this may be fixed in current levels (haven't tried it in a while). In any event, putting 4 GB on the system will help some, since that would eliminate the risk of doing any paging, assuming you're not running much else other than Tomcat. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

There is a default webapp per host, not per Tomcat. (However, the path attribute must not be used unless the Context/ entry is in server.xml, and that is strongly discouraged these days.) To quote from the Tomcat server reference doc for the path attribute: The context path of this web application, which is matched against the beginning of each request URI to select the appropriate web application for processing. All of the context paths within a particular Host must be unique. If you specify a context path of an empty string (), you are defining the default web application for this Host, which will process all requests not assigned to other Contexts. The value of this field must not be set except when statically defining a Context in server.xml, as it will be infered from the filenames used for either the .xml context file or the docBase.

RE: configure HTTP1.1 pipline depth on Tomcat 5.0
From: charly [mailto:[EMAIL PROTECTED] Subject: Re: configure HTTP1.1 pipline depth on Tomcat 5.0 AFAIK the pipeline length cannot be more than one by design. No client will send another request before it received the response from the last. To quote from RFC 2616 (section 8.1.1): HTTP requests and responses can be pipelined on a connection. Pipelining allows a client to make multiple requests without waiting for each response, allowing a single TCP connection to be used much more efficiently, with much lower elapsed time. And in 8.1.2: A significant difference between HTTP/1.1 and earlier versions of HTTP is that persistent connections are the default behavior of any HTTP connection. That is, unless otherwise indicated, the client SHOULD assume that the server will maintain a persistent connection, even after error responses from the server. And so TC will also not accept another request before it processed the last Can you tell us where in the Tomcat code such a restriction is implemented?

I haven't been able to find it, although I'm certainly not an expert on Tomcat internals. To answer my own question, the serialization of requests occurs in: org.apache.coyote.http11.Http11Processor where there's a loop in the process() method that insures each pipelined request is responded to before starting on the next. Note that this is a serialization of processing, not accepting, so there does not appear to be any limit on the number of requests that can be pipelined together in a single transmission. There is a configurable limit on the number of keep alives that will be tolerated on an otherwise idle connection. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

It would help if you told us what Tomcat level you're using. Unfortunately, the comments in server.xml appear to be left over from some past life, so actually reading the documentation is a necessity. There is no compressionMinSize attribute identified in the 4.1, 5.0, or 5.5 docs (or the code, as far as I can tell); if you're using a level older than that, you've got other problems to worry about. For 5.5, the actual description for compression is: -- The Connector may use HTTP/1.1 GZIP compression in an attempt to save server bandwidth. The acceptable values for the parameter is off (disable compression), on (allow compression, which causes text data to be compressed), force (forces compression in all cases), or a numerical integer value (which is equivalent to on, but specifies the minimum amount of data before the output is compressed). If the content-length is not known and compression is set to on or more aggressive, the output will also be compressed. If not specified, this attribute is set to off. -- The doc fails to say what the default minimum compression size is, so I tried compression=force, and all the content now appears properly garbled in Ethereal. Also, take a look at compressableMimeType: -- The value is a comma separated list of MIME types for which HTTP compression may be used.

From: Chris Burdess [mailto:[EMAIL PROTECTED] Subject: Possible bug in request parameter decoding According to http://www.w3.org/TR/html40/appendix/notes.html#non-ascii-chars request parameters are encoded in UTF-8. Well, that's not quite how I read it. By definition (RFC 2396), URIs are not supposed to contain non-ASCII values. The HTML 4.0 appendix referred to above makes the somewhat contradictory suggestion to use UTF-8 to handle non-ASCII, ignoring the fact that UTF-8 encoding produces byte values outside of the ASCII range. Since the discussion in this area of the appendix is related to browser, not server, behavior, it's not really relevant to what Tomcat should do when it encounters illegal (non-ASCII) values in a URI supplied on a browser request. In any event, as Tim noted, you can configure how the connector should interpret non-ASCII bytes by specifying a value for URIEncoding in your server.xml file. I suspect that the default value of ISO-8859-1 is there largely for historical reasons, since it was the predominant encoding before UTF-8 became popular. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

RE: Tomcat 5.0.30 OutOfMemory error
From: Jack Park [mailto:[EMAIL PROTECTED] Subject: Tomcat 5.0.30 OutOfMemory error It would be helpful if you told us what OS you're using, along with what version of the JDK you have installed. Did you check your logs for any pertinent diagnostic information? The java process is calling up 66,500k of heap so it strikes me that the OutOfMemory issue isn't related to the heap. Highly likely that it's not complete heap exhaustion. If you've searched the archives at all, you should have found the following: 1) The OutOfMemoryError is a catch-all for exhausting not only the heap, but also pretty much any system resource, such as the number of open files. You need to look at the stack trace in the logs to find out what was being attempted at the time. 2) You can run out of Perm Gen space rather easily in any app server. Look at the JVM documentation and the archives for details. If I try to place set CATALINA_OPTS= -Xms256m -Xmx512m -Xss512k in catalina.bat, Tomcat won't start at all.

RE: Recompiling jsp; Problems with Access Denied errors after I edit a file in a webapp; Admin app
From: Karr, David [mailto:[EMAIL PROTECTED] Subject: Recompiling jsp; Problems with Access Denied errors after I edit a file in a webapp; Admin app First of all, what is the admin app? The admin app lets you view and manipulate nearly all Tomcat configuration values. It's a web-based interface to the myriad of .xml files. it says I must download and install the admin package. The admin package is the .zip file called, cleverly enough, admin on the Tomcat download page. Just download and unzip it, using the same base directory in which Tomcat is installed. Is it feasible to have the actual webapp location be outside of the Tomcat distribution? Yes, read the how-to on deployment. that seems to cause Tomcat to fail with Access denied errors on the files that I edited. I suspect you're running Tomcat as a service, with its own account (by default, SYSTEM). When you edited the file under your account, the ownership changed, and Tomcat no longer had access. You should be able to fix this by specifying the proper security on the directories and files you want Tomcat to use. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

RE: question about load-on-startup in web.xml
From: Annie Wang [mailto:[EMAIL PROTECTED] Subject: Re: question about load-on-startup in web.xml any one know if there's a way to make webappY get installed before webappX? As far as I can tell, the intent of the JSP and servlet specs is for web applications to be independent of both the container and each other. Since Tomcat is the reference implementation for the spec, the developers seem to avoid introducing many Tomcat-unique features that would reduce application portability. The load-on-startup tag is part of the servlet spec, defined to control instantiation of servlets within an app, not across apps. If you want to synchronize application deployment, I think you're going to have to do that within the app itself, possibly with context listeners to minimize inter-app dependencies. You'd probably want to use reflection to make references to whatever class or object you synchronize on, otherwise you're going to have problems independently updating the apps without taking Tomcat down. Another option, of course, is to extend the existing deployOnStartup mechanism to do what you want. After all, this is open-source. Or maybe there's some neat trick I haven't found yet. what determines the install order? These references only partially answer the question: http://jakarta.apache.org/tomcat/tomcat-5.5-doc/deployer-howto.html#Depl oying%20on%20Tomcat%20startup http://jakarta.apache.org/tomcat/tomcat-5.5-doc/config/host.html#Automat ic%20Application%20Deployment My somewhat less than rigorous experimentation seems to indicate that apps are deployed serially, not in parallel, but I haven't tried to figure out what determines the order. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

RE: Non-Sequitor Stack Trace with no log entry
From: Mark Leone [mailto:[EMAIL PROTECTED]
Subject: Non-Sequitor Stack Trace with no log entry
However, the method I'm calling does not throw that exception,
and I looked at all the relevant source code over and over
again, and it's simply not possible to hit any code that
references SOAPException by invoking newDocument().
The NoClassDefFoundError exception can be generated without any explicit
references in the path you're taking. For example, try the following
test program:
class TestReference {
static public void main(String args[]) {
System.out.println(starting up);
if (args.length 0 args[0].equals(testing)) {
System.out.println(calling testmethod);
try {
testmethod();
} catch (Exception e) {
System.out.println(Caught + e);
}
} else {
System.out.println(ignoring testmethod);
}
}
static void testmethod() throws MyException {
throw new MyException(testing);
}
}
class MyException extends Exception {
public MyException(String message) {
super(message);
}
}
If you compile this and then delete MyException.class or make it
otherwise unavailable at run time, you get the NCDFE message during the
linking of TestReference - regardless of any argument specified and
before any code in the TestReference class is actually executed. The
point to note here is that the referenced exception class must be
available at run time, even if that exception is not actually going to
be thrown.
The class of interest (javax.xml.soap.SOAPException) is located in
saaj.jar (part of the Axis download); you'll need to put at least that
in the same directory as axis.jar. There are other jars included with
Axis, so you may need those as well.

RE: How to run tomcat without specifying a JDK location?
From: Lakshmi Narayanan K. [mailto:[EMAIL PROTECTED] Subject: Re: How to run tomcat without specifying a JDK location? 1) What is the role of the tools.jar file? Does it help in compilation of JSP's? I mean, is tools.jar enough to compile JSP's without a JDK? Among other things, tools.jar contains the various class files that comprise javac, so that's all you need to compile .java files. In order to translate JSPs into Java source, you need jasper, and that's already part of the Tomcat distribution. I think you can just put tools.jar into common/lib, but I haven't actually tried it. You can also just create a lib directory under the directory JAVA_HOME points to, and put tools.jar there (I have done that).

RE: Why 8080 and 8443 ..?
From: Michael Mehrle [mailto:[EMAIL PROTECTED] Subject: Re: Why 8080 and 8443 ..? Which are ??? Please feel free to elaborate ;-) As Jason mentioned, running Tomcat in production requires configuring the desired connectors and the various internal and external resources, and also stripping out the excess apps and other demo parameters. Configuring appropriate security (not plain-text passwords) for the manager and admin web apps, and using a non-default shutdown key are also highly recommended. Beyond that, at least these attributes (in various .xml files) may need to be changed to reduce overhead or better fit a production environment: autoDeploy input listings output classdebuginfo development keepgenerated mappedfile trimSpaces suppressSmap Several of the above apply to JSP compilation, so if you're doing precompilation (desirable for production), your ANT scripts should set/clear the corresponding parameters.

RE: Problem with the classloader in jakarta-tomcat-5.0.28 - cannot add a jar file to class repository

However, if you add a reference to the actual jar file (eg,
shared.loader=${catalina.home}/shared/lib/velocity-dep-1.3.1.j
ar) you will not be able to use any classes from it but
rather will get ClassNotFoundException. This is the actual problem!
This appears to be the same situation described in Bugzilla entry 23344
(see
http://issues.apache.org/bugzilla/show_bug.cgi?id=23344
for details) which was marked as fixed in September 2003 in level
5.0.12. Apparently, individual jars should be added as URLs rather than
normal file system paths. I suppose that means using
file:///path/file.jar, but I haven't tried it.

RE: OutOfMemoryError - 100 thread limit?
From: J. Ryan Earl [mailto:[EMAIL PROTECTED] Subject: RE: OutOfMemoryError - 100 thread limit? So let me get this straight, LeeAnn is specifying a maximum heap size of 512MB and a minimum size of 128MB. It looks like the heap doesn't get adjusted up when the servlets are initializing? Thus she needs to increase her minimum heapsize, so something like -Xms512m should fix it? Probably not, since I suspect she's running out of perm gen space. IIRC, the perm gen size is calculated from -Xmx, which is already at 512m. Using the PrintGCDetails will tell us for sure. If that shows perm gen space to be exhausted, then adjusting -XX:MaxPermSize should fix it. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Also, his conjecture that the JVM couldn't keep up doesn't fit with my understanding of object allocation and GC in a HotSpot JVM. If needed, the JVM simply suspends all the application threads and does a full GC.

Can anyone give me any information on what this does? Is this the perm gen that Chuck mentioned before? Yes, this controls the size of the permanent generation. The permanent generation portion of the heap is where class objects (instances of java.lang.Class) are allocated. If you have a lot of classes - which app servers frequently do - the size of this space needs to be increased. A quick scan of the 1.4.2 HotSpot source shows the default value to be 64m. Are there any caveats to setting this memory option?

RE: OutOfMemoryError - 100 thread limit?
From: Peter Lin [mailto:[EMAIL PROTECTED] Subject: Re: OutOfMemoryError - 100 thread limit? I'm just guessing here, but by forcing the maxPermSize to 128, it leaves more space for the eden and prevents classes from getting promoted to perm. I think you're confusing tenured with perm. Nothing is ever promoted to perm - only known long-lived objects (primarily instances of java.lang.Class) are allocated in there, and no objects ever migrate to or from perm space. Regular objects are normally allocated in eden space (young gen), and if they live long enough, are migrated to the tenured area (old gen) during a GC. Increasing the perm size actually reduces, not increases, the amount of eden space available since the total of all three generations (young, old, perm) must come from the -Xmx setting. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

RE: OutOfMemoryError - 100 thread limit?
From: Peter Lin [mailto:[EMAIL PROTECTED] Subject: Re: OutOfMemoryError - 100 thread limit? so it would appear by setting the PermSize, the jvm is pushing all java.lang.Class instances to Perm rather than loading them in eden and then promoting them to tenured. Instances of java.lang.Class are always allocated in the perm gen, never in an eden space, regardless of any heap or gen size settings. I can't think of any real trade-offs of setting Perm to 128 other than using more RAM. Unless you increase -Xmx correspondingly, enlarging perm space will reduce the amount available for regular objects. Generally, if you have the memory, increase -Xmx to whatever you can before swapping starts. If I remember correctly Perm is also where static stuff goes. I believe that's true, since static data is associated with java.lang.Class instances. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

RE: OutOfMemoryError - 100 thread limit?
From: Peter Lin [mailto:[EMAIL PROTECTED] Subject: Re: OutOfMemoryError - 100 thread limit? the default Perm is 64M. If LeeAnn's webapp have a large number of classes, maybe there's too many; therefore forcing the VM to resize the perm. IIRC (haven't looked at core HotSpot code in detail since 1.4.1 days), the virtual address boundary between perm and the other generations is fixed at JVM initialization and never moves. The perm gen does go through GC just like the other gens, but no memory ever moves between the perm and any other space, and the perm gen maximum virtual address range never changes. The HotSpot JVM allocates, but does not commit, all of the -Xmx space at startup in one contiguous block (although there were rumors of that changing in later JVMs). Only the -Xms portion is committed, split up into three regions - young, old, and perm. When a region fills and GC doesn't reduce the usage significantly, additional pages are committed in whichever region needs expanding. I think what was happening is that LeeAnn simply had more classes than would fit in 64 MB. Nothing to do with threads, just the total number of classes in all the applications added together. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

From: Joe Reger, Jr. [mailto:[EMAIL PROTECTED] Subject: Tomcat Won't Start When 1024Mb JVM Memory Specified Is there a 1Gb limit on the JVM? On Tomcat?

RE: Help !!! Tomcat 5.5.7 - cannot start
From: Anoop kumar V [mailto:[EMAIL PROTECTED] Subject: Re: Help !!! Tomcat 5.5.7 - cannot start The jars that have been added to the classpath are shown - ensure that u have catalina.jar or j2ee.jar. Sorry, but that advice is simply wrong and following it can produce serious Tomcat classloading problems. If you are using the standard startup and shutdown scripts supplied with the Tomcat download, the CLASSPATH environment variable is not used. Instead, the scripts set the -cp parameter based on CATALINA_HOME, and the only item that should be specified there is bootstrap.jar from $CATALINA_HOME/bin. Tomcat does not need the j2ee.jar at all, and placing it within the Tomcat environment can cause duplicate class problems with the subset of J2EE that is already included in the Tomcat download. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

RE: Help !!! Tomcat 5.5.7 - cannot start
From: Parveen Pasha [mailto:[EMAIL PROTECTED] Subject: RE: Help !!! Tomcat 5.5.7 - cannot start The output from catalina.out is : java.lang.ClassNotFoundException: org.apache.catalina.startup.Catalina at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) Does the user doing the shutdown have proper access to the Tomcat files? That particular class comes from catalina.jar in the $CATALINA_HOME/server/lib directory. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
