Re: Inconsistent output of Java 5 enums
Hi all,
Am Thursday 14 October 2010 schrieb Christopher Schultz:
> So I'm surprised that Oliver is getting that weird output.
I wrote in my initial mail to this list "I have an enum that has an overridden
toString() method". I thought it was clear what that means, obviously it was
not. Sorry for the confusion. So this is a simplified example for my enum:
public enum MyEnum {
VALID(0),
INVALID(1);
private final int code;
private MyEnum(int code) {
this.code = code;
}
@Override
public String toString() {
return name() + " result, code: " + code;
}
}
My JSP looks like this:
Output per EL: ${myEnumValue}
Output per JSTL:
The output is:
Output per EL: VALID
Output per JSTL: VALID result, code 0
The thing is, that EL is using the name() method to print the enum and JSTL is
using toString(). I did not expect a different enum treatment here.
One possible explaination is that Pid is right when he says "The related
sources jar was built in 2006, and the pom for that indicates that it's
dependent on JSP 2.0, rather than 2.1". Does anyone know if a true JSTL 1.2
using JSP 2.1 is available in the maven repository? Anyway I will try a
manually downloaded version tonight.
Bye
Oliver

Re: Tomcat LoadBalancing
Hello All, As I have already told you guys that I want to achieve Load balancing within Tomcat servers. In this configuration head Tomcat server will get request from apache web server and then distribute that load among the Tomcat load balancers members. But as Mark told us that Tomcat is not supporting reverse proxy . will this be possible for me to achieve this configuration. I have attached a document with said architecture . Should I continue with this configuration or make some changes to it. I will be very thankful if you guys give me some idea about that.

Some reasons you may choose to put a httpd reverse proxy in front of tomcat: - Allows displaying a "this site is down for maintenance" message when you have taken your tomcat down for maintenance. - Many third party security products supply agents as an apache httpd plugin. - httpd can be used as a load balancer to a farm of tomcat processes. - you may prefer to have the web access logging granularity that httpd provides. It really depends on your situation. Cheers, Ben - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

The chapter 1.18.2 of the Expression Language Specification Version
2.1, Final Release - May 8, 2006 (a part of JSR-000245: JSP 2.1)
defines how an EL expression is coerced to a String.
One of the points there is
* "Otherwise, if A is Enum, return A.name()"

He's overriden the .toString method, no?
EL must be recognising it's an Enum and treating it differently.
There's a spec for that, so it'll probably define what to do with an Enum.

Answer to my own question:
public class EnumTest
{
public enum Weekday {
SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY
}
public static void main(String[] args)
{
System.out.println(Weekday.SUNDAY);
}
}
This produces "SUNDAY" as output.
The EnumTest.Weekday "class" doesn't override the toString method,
allowing java.lang.Enum (it's superclass) to handle that.
java.lang.Enum.toString is implemented like this:
public String toString()
{
return name;
}
... and "name" is a String which is initialized in the constructor (when
I decompile EnumTest.Weekday, I can see it uses the string "Sunday", as
one might expect).
So I'm surprised that Oliver is getting that weird output.

While I am not a Tomcat developer, I can speak to the performance of Tomcat with regard to static files: if you use the APR or NIO connectors with sendFile="true", your performance will be on par with Apache httpd. The blocking (default) connector has pretty horrible performance, comparably. That being said, I have tested a variety of static file sizes, and if you have files that are less than about 64KiB in size, it doesn't matter what connector you use. *I'll repeat that for emphasis: all connectors perform the same with static files up to about 64KiB in size.* My tests were done against Tomcat 6.0.20 and Apache httpd 2.2.11. > If so, I would encourage you to update the wiki... > > http://wiki.apache.org/tomcat/FAQ/Connectors > > because it mentions that Apache is faster at serving static content than > Tomcat for high-traffic sites. It says that "historically, Apache httpd has been faster". Unfortunately, it does not say that this is no longer true. There's also another piece of this puzzle: the use of Apache httpd makes all your dynamic requests that must be proxied to Tomcat slower. So, the question is this: do you get more static of dynamic requests? If you get more static requests than dynamic requests, maybe running Apache httpd out front might make sense. If you have only a few static requests and mostly dynamic ones, you may be optimizing 1% of your traffic and de-optimizing 99% of it. There is also another option: use an image server. Don't put your static files on the same server as your (dynamic) webapp. Then, have that other server serve those files hopefully faster. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAky3UrgACgkQ9CaO5/Lv0PC5sQCfbd9VQh10Fj93LwcTB1x4wAmg dBkAoMQGaQUFPyntawbVDaFSt4YTThCK =CQ2+ -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

That looks like the one that worked properly for me.
I unfortunately know very little about the JSTL and it's interaction
with POJOs. I would expect that value="${enum}" would somehow convert
the value to a String for inclusion into the output stream, and calling
EnumType.toString sounds like the right thing to do.
Can you look at the translated .java file that comes from your sample
.jsp and post what the JSP compiler has generated?
This might be a bug, but I'm not really sure. What if the object is not

You do not need to uninstall prior versions, but you certainly don't want to install on top of an existing version. Always install in a different location, configure the new version, then update scripts as needed to point to the new spot. (The above presumes you're installing a real Tomcat downloaded from tomcat.apache.org; if you're using a 3rd-party repackaged version, you're on your own.) - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Apache Reverse Proxy required or not?
Hi All, Quick question on what people's views are with regard to using Tomcat to host external/internet facing sites. A quick Google search recommends that these should be 'fronted' by Apache running reverse proxy. Is Tomcat classed as insecure and as such requires this proxy in front or is this due to the fact that Tomcat cannot reverse proxy on its own. Cheers Rob

[I'm wincing & extending a cordial offer of some sandbags] Getting the actual question out of the way first: you're looking for an access log, which is (usually) defined inside the Host element, as per: http://tomcat.apache.org/tomcat-6.0-doc/config/valve.html#Access_Log_Valve The logs are usually found in your tomcat/logs directory. Addressing the indirect assertion second: Tomcat can serve static files just as efficiently as Apache HTTPD, it's an old, out-of-date belief that it can't. There's a distinct possibility that this thread will shortly contain a series of messages which explain how & why... p > Thanks, - Dave 0x62590808.asc Description: application/pgp-keys signature.asc Description: OpenPGP digital signature

If you really are using CATALINA_BASE/conf/[enginename]/[hostname]/[appname].xml, then I wouldn't expect anything to be copied into CATALINA_BASE/webapps during deployment. Instead, the WAR should be exploded into the CATALINA_BASE/work directory.

If you want your server to be as efficient as possible, you should use an which will allow the request processing threads to be destroyed during times of low activity. It's not really that big of a deal, but it's worth mentioning. A couple more questions: 1. How large are the requests you are processing? Is the usage profile the same for "high load" versus "low load" situations -- other than the actual frequency of requests, of course. 2. Are you using a database of any kind? If so, can you post the configuration for that (minus any sensitive information, of course)? 90 seconds would be a very low timeout for a database connection, but it's possible that you have a bottleneck in your application that somehow only appears when you're nearly idle. 3. Is some other process running on the server during these low-load times? Maybe some cron job or heavy reporting operation or something? - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAky3HvUACgkQ9CaO5/Lv0PDK4gCeOJaCAXqQfB4C9EA0kYdrjRpt 0pAAn2EURuQAExb7lfBahaSdG5u2cshc =Sw5F -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Just a note: 5.5.20 is over 4 years old. You should really upgrade to 5.5.30 or even to 6.0.29. Upgrading from 5.5 to 6.0 is pretty seamless. Are you using a 32-bit of 64-bit JVM?

How to resolve the > problem? Note the entire message: "java.lang.OutOfMemoryError: unable to create new native thread". It doesn't say it's out of heap space, it says that it can't create a new native thread. There are a couple of reasons this could happen: 1. The Tomcat user cannot create any more threads because of a thread limit within a single process. Windows can limit the number of threads a process can create as a security and resource management mechanism. 2. The process can't create another thread due to the available (native) memory and the stack size you have for a thread. This page has some good information about thread limits on Windows: http://blogs.technet.com/b/markrussinovich/archive/2009/07/08/3261309.aspx Can you post all of the JVM arguments you are using to start Java? Could you also post all the elements from your conf/server.xml file? Finally, can you comment on the use of any threads within your own application that are /not/ managed by Tomcat?

Could it be that your application is starting new threads, but not disposing of them properly? If it is a memory exhaustion situation, you should be able to find numerous discussions on how to pinpoint memory leaks in applications running under Tomcat. Some of the memory analysis techniques might help in resolving thread exhaustion issues, too (if you can locate the unexpected thread objects and find what is keeping them alive). Another way to find out about the threads is to produce a thread dump of the running JVM (that also has been often discussed on this list). - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

RE: upgrading apache tomcat on windows 2003
Thanks for the quick response Rob, So it is possible to use the installer to upgrade. I don't have to uninstall and then re-install. You suggest removing the service and continuing with the install. I would like to find procedures that detail the steps to do when upgrading from one version to another on a windows system. I have tried looking for upgrade documentation on the net and I can't find any.

RE: upgrading apache tomcat on windows 2003
Can you not just manually remove the existing service i.e. from a cmd prompt:- sc delete You can determine the name of the service from the services option within control panel but guessing it is called Tomcat.

upgrading apache tomcat on windows 2003
Good Morning, I am trying to upgrade from apache tomcat version 5.5.20 to 5.5.31 on a windows 2003 system. I downloaded the apache-tomcat-5.5.31.exe to my server and started the install. I stopped the existing tomcat-apache service. I noticed that there is no upgrade option so I continued with the install option. everything was ok until a hit the following error--> Failed to install Tomcat5 service. Check you settings and permissions. Ignore and continue anyway (not recommended) So my question is how to upgrade from one version to another. Do I have to un-install and re-install the latest version. Thanks Paul Primeau CGI Engineering & Technical Support ETS Midrange Service Line PWGSC - ITSB - SM&D mailto:paul.prim...@pwgsc.gc.ca

There is (currently) no reverse proxy capability in Tomcat. It has been talked about a few times but never written.
