client disconnect
Yoav, I understand that the spec says that the container may throw an exception at client disconnection. I understand it and I will cope with that. Wat was unbelievable to me was that even when the other side of the stream is clearly closed you can still write in it and flush it without it telling to you nada. zip. So you are sure that what you wrote arived safely to the other side. and guess what . In fact it didn't. I don't think you as a programmer would like to rely on such infrastructure. Whatever the specs may say.

Re: high server load
I configured the fork-setting to true and the load went down from 10 to 1.5 so the configuration helped a lot. Also the server availibility was enhanced. Is there still another configuration parameter which could decrease the load under 1.0 or do we need to buy better hardware ;) So thank you for your help, Jouko Shapira, Yoav wrote: Hi, It's kind of hard to help with a non-existent tomcat version ;) Do things improve if you set fork to true for your JSP servlet? Tomcat 4 and 5 have different memory models, different optimization, etc, so the performance characteristics for the same app under the same load will not be the same between them. They should be better in tomcat 5, of course. Yoav Shapira Millennium Research Informatics -Original Message- From: Jouko Johansson [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 15, 2004 6:18 AM To: Tomcat Users List Subject: high server load Hi, I have experienced some problems while testing the tomcat 5.0.28 on linux. After the restart the tomcat is running without any problems. After 3 to 4 hours the server load starts to increase. Even though the server load is very high (30), the tomcat response time is very good. I assume that there is a some kind of problem with background thread which increases the load because the server still provides the service. I have decreased the server load to 10 with configuring the maxSpareThread-value to same as maxThreads-value. The server handles about 10-20 req/sec, so maybe the maxThreads-value is too high. The same web application is running fluently with version 4.0.6 on another application server. The garbage collection takes about 0.1 secs to complete and full garbage collection takes about 1-2 seconds. The running java process count is 222.

Re: Setting JAVA_HOME and CATALINA_HOME on XP
On WinXP you will want to set these in the Environment Variables located under properties of My Computer. You can get there by right clicking on the My Computer icon and selecting properties. When the new window comes up click on the Advance tab and then select the Environment Variables button located at the bottom of the screen. This is where you will set up the new System Variables for the applications. CATALINA_HOME and JAKARTA_HOME as System variables click on the new button and then insert the information required. For example: Variable Name: CATALINA_HOME Variable Value: c:\tomcat Variable Value being the root directory for the tomcat installation. This may differ with your setup. Let me know if you have any questions on this. Jason L.

JK2: lb_factor
Hello, I've got a cluster with 2 tomcat 2.0.25 on different machines, on one of them also running Apache 2.0.49 with JK2 as a loadbalancer. Requests get redirected to both tomcat instances, but it always ends up with around 1/3 of all requests at the local server and about 2/3 at the remote one, no matter what value the lb_factors are. So, could anyone tell me which values I should use to make the lb_factor work correctly?

RE: JK2: lb_factor
The quality of the distribution depends on the worker type of apache. (AFAIK only the 'worker' MPM will work) Nevertheless AFAIK the load balancing in mod_jk is not complete in this area, so I'm not shure if you will get the desired distribution (but it should be closer). -Original Message- From: Weseloh, Nicole [mailto:[EMAIL PROTECTED] Sent: Wednesday, June 16, 2004 11:48 AM To: [EMAIL PROTECTED] Subject: JK2: lb_factor I've got a cluster with 2 tomcat 2.0.25 on different machines, on one of them also running Apache 2.0.49 with JK2 as a loadbalancer.

[OT] Problem unzipping files in servlet with german umlauts in filenames of zipentries.
Hello, I hope somebody can help me with this problem. I have a servlet in my application which unzips a uploaded zip archive and stores the contained files. This works fine until the filename of a zipentry contains german umlauts. For example in a zipfile a.zip is an entry äöü.txt. When i get the ZipEntry for that file zipEntry.getName() returns me ???.txt instead of äöü.txt. I think this has something to do with the right Characterencoding but I don't know how to do it. thanks in advance Martin - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Apache and Tomcat - Apache.exe application error
Greetings. I am having a problem with Apache 2.0.49 causing an Application Error on Windows. I know this is the tomcat list - but the issue ony crops up when using mod_jk2 with Tomcat - so I am posting here in case anyone has any ideas?! I have also posted a bug report on the HTTPD bugzilla. I am using Apache 2.0.49 with (major non-standard mods): mod_ssl mod_jk2 with Tomcat 5.0.x being connected to via mod_jk2. I am running on Windows XP Professional, as well as Windows 2000 Server, Windows 2000 Advanced Server, Windows 2003 Server. In all cases I have installed the Apache2 service using the Apache.exe -k install mechanism. When restarting the service using: - net stop Apache2 - The ApacheMonitor interface - The services control panel in windows I invariably get the following dialog popping up: Apache.exe - Application Error The instruction at 0x77f51baa referenced memory at 0x0010. The memory could not be written. If you cick OK or Cancel, the popup dialog eternally pops straight back up. Apache DOES actually stop and start OK - but the popup cannot be minimized, closed or anything. It is VERY annoying. Could this have to do with the Tomcat mod_jk - specifcally the sharded memory file (SHM) that both Tomcat and Apache use for workers (if I am understanding that correctly)? This bug was definitely NOT around when I was using Apache 2.0.46 and mod_jk2.02/3, but since upgrading to Apache2.0.49 and mod_jk2.04/5dev it has started. Funny thing is it does NOT happen on all servers! Any assistance would be greatly appreciated!

Order of WebApp Loading
Hi Everybody I am using Tomcat 4.1.29 and i have several webapps in my application. I want to set one webapp to load first and the rest of the webapps should be loaded after it. I have tried changing the order in server.xml, but it didn'y help. Is there any way i can set the order of webapp loading ? Thanks Surendra . - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Configuring JNDI for tomcat
Sounds like nothing's running on localhost port 1099. I'm not a Tomcat expert so I
don't know if Tomcat is supposed to be exposing its Naming Service on that port. If
it is, it isn't there.

Subject: Configuring JNDI for tomcat
Hi, I am trying to configure tomcat 5.025 on W2K to be accessible by other machines
via JNDI. I have tried using the registry method but am getting Connection refused.
And when I try to filesystem approach I get NameNotFoundException.
I am new to both Tomcat and JNDI and hope to get some pointers.
The way I'm testing now(local machine first) is I run tomcat with my server resource
which I want to make accessible, then I try to connect by running my client code via
the java command on my command prompt.
The following is how I am trying with the registry approach -
(jndi.properties in C:\j2sdk1.4.2_04\jre\lib)
java.naming.factory.initial=com.sun.jndi.rmi.registry.RegistryContextFactory
java.naming.provider.url=rmi:localhost:1099

(JndiBean class in C:\jakarta-tomcat-5.0.25\webapps\iccs\WEB-INF\classes\test)
package test;
public class JndiBean {
private String foo = Default Foo;
public String getFoo() { return (this.foo); }
public void setFoo(String foo) { this.foo = foo; }
private int bar = 0;
public int getBar() { return (this.bar); }
public void setBar(int bar) { this.bar = bar; }
}
(JndiClient class in C:\jakarta-tomcat-5.0.25\webapps\iccs\WEB-INF\classes\test)
package test;
import javax.naming.*;
public class JndiClient {
public static void main(String[] args) {
try {
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup(java:comp/env);
JndiBean bean = (JndiBean) envCtx.lookup(bean/Jndi);
System.out.println(foo = + bean.getFoo() + , bar = + bean.getBar());
}
catch( Exception e ) { e.printStackTrace(); }
}
}
And here is the error that I get
C:\java -classpath C:\jakarta-tomcat-5.0.25\webapps\iccs\WEB-INF\classes

AW: JK2: lb_factor
Hello Ralph, could you please explain what you mean by that?

(OS of the server is Win XP Pro) If so - can you tell me how to do that? Just a configuration in httpd.conf? Or do I need to recompile Apache? (yes, I know how to read docs - only need some advice where to look...) Oh, and just to be sure - I'm using JK2, are you talking about that, or do you refer to JK / mod_jk?

Hehe, really interesting. My next step is to set up a second Tomcat instance + mod_jk on the same box. Another Solaris box is on its way but won't be available very soon. Ok, to resume: QM, your suggestions might be a good quick-fix-how-to for this kind of problems.

RE: Parameters and where is log
Hi, If you can't see System.out/System.err output anywhere, something serious is wrong, such as the server not starting properly: kill it, clean out your logs, start it again and watch the logs carefully.

RE: Multiple requests sharing the same Servlet instance
Hi, No, it doesn't mean one instance of a servlet class is created.

RE: Multiple requests sharing the same Servlet instance
Hi, But if a Servlet instance might be used by multiple threads at one time, then what's the point of having Servlet object pooling at all? Why wouldn't It might and it might not. My point was that the Servlet Spec leaves it for the container implementation to decide, and so you should be careful. all requests just use one instance? I still don't see how I can have variables that are just for storing a single thread's working data. The You can do so easily inside any method, or in ThreadLocal variables, or in request-scope attributes, or in other non-servlet object pools that you write (or use a 3rd party pooling library). The ways are plentiful and except for the request attributes they're not specific to servlet containers (nor is this issue in general specific to servlet containers). way I can do anything like this is to attach attributes to the request. But this seems to be a kludge to me. I don't want to have to use Strings to get to my data by way of a Map. I want regular Java local variables.

Re: Multiple requests sharing the same Servlet instance
It depends on what you mean by state. State can be maintained in many places, each for their own purpose: 1) ServletContext - So all servlets may access the same data 2) Session - User specific state 3) Servlet - resources that are of value only to that servlet. 4) static variables - Available to any class in the classloader. The most dangerous way to maintain state but sometimes a needed evil. The original intent was to have servlets allocated objects and multiple requests each hit the same servlet instance. I would imagine there was an intent to allow admins to configure a servlet to allow for a maximum number of concurrent requests flowing into the same servlet instance at one time. If the limit was reached - new instances would be created. In reality, no one implemented it because it was pretty stupid. Its much easier to have all request got through the same instance and let the servlet worry about the shared resource issues. -Tim Keith Hankin wrote: Maybe I'm being dumb, but it seems to me that based upon what I'm hearing, there is no benefit of doing Servlet instance pooling since the Servlets aren't true objects; they are merely places to put code, since no local state is useful. - Original Message - From: Shapira, Yoav [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED] Sent: Wednesday, June 16, 2004 7:06 PM Subject: RE: Multiple requests sharing the same Servlet instance Hi, But if a Servlet instance might be used by multiple threads at one time, then what's the point of having Servlet object pooling at all?

Problem accessing WEB-INF/lib (Launching Tomcat from Eclipse without any plugins)
Hi, I did set up Eclipse to run Tomcat. When I run Tomcat 5 standalone (I mean NOT from Eclipse) I don't have this problem. My application can't access WEB-INF/lib unless I also put all *.jar files in classpath. I know this should not be required and Tomcat would normally access them without classpath. I configured Eclipse as follows: Main class: org.apache.catalina.startup.Bootstrap Program arguments: start VM arguments: -Djava.endorsed.dirs=c:\java\tomcat\common\endorsed -Dcatalina.base=c:\java\tomcat -Dcatalina.home=c:\java\tomcat -Djava.io.tmpdir=c:\java\tomcat\temp Local directory: C:\Java\tomcat\bin Classpath bootstrap entries: c:\Java\jdk\jre\lib\rt.jar User entries: bootstrap.jar (TOMCAT) and tools.jar (JDK) Tomcat starts correctly but I get NoClassDefException when main application servlet tries to call that JAR (when running from Eclipse). I am sure I have that JAR in my WEB-INF/lib. I don't understand how does Tomcat know it has to make WEB-INF/lib available and why it doesn't do it when I try to run it from Eclipse. Did I miss any settings? My best regards, Vladas P.S. There is workaround by explicitly putting all jars in classpath but I am very anxious to understand why this is happening.

Vexing session creation issue

This JSP opens a new window via JavaScript and loads into it index1.jsp. index1.jsp populates five frames of a frameset. At the end of all this, my logon screen is seen. The important thing to note here is that no Actions are executed to this point, it's just loading JSP's, and there is not really any JSP code in any of these except for a bunch of request.getContextPath() calls. No code accesses session or anything like that, and there are only two references to getting anything out of request (because the logon page might be shown after a bad attempt, and I need to get the userID and password that was attempted). In all of them, I have session=false in the page tag. Now... I've created a SessionListener to tell me when a session is created or destroyed. Problem is, during all these JSP loads, the create event fires TWICE! What's worse, session is NOT null (which I expected it to be), and worse still, I'm getting two DIFFERENT session ID's! It looks like two sessions are being created when it seems like absolutely NONE should be. I'm banging my head against the wall with this one. Anyone have any ideas? Thanks folks!

Re: Multiple requests sharing the same Servlet instance
since the Servlets aren't true objects A servlet is a true object. It gets instanciated by the container. since no local state is useful. All the variables declared in your service methods (doPost, doGet) are local to a particular request. You also have access to application, session, and page scoped variables. The servlet spec is a good read if you want to understand when and why an evironment will opt for multiple instances of a particular servlet. === Example: === SRV.2.2 Number of Instances The servlet declaration which is part of the deployment descriptor of theWeb application containing the servlet, as described in Chapter SRV.13, Deployment Descriptor , controls how the servlet container provides instances of the servlet. For a servlet not hosted in a distributed environment (the default), the servlet container must use only one instance per servlet declaration. However, for a servlet implementing the SingleThreadModel interface, the servlet container may instantiate multiple instances to handle a heavy request load and serialize requests to a particular instance. === As a rule, I only use instance variables that are static and are initialized in the servlet's init method.

RE: Vexing session creation issue
Hi, The behavior you're seeing is consistent with the servlet specification. If a client chooses not to join a session (which the page session=false directive indicates), the container may still create sessions for the client, just that it will be a new session each time, with a new ID and empty attributes. This is in the Servlet Spec but summarized nicely in the 2nd to last paragraph of the HttpSession class JavaDoc.

RE: Vexing session creation issue
This is what my research is indicating too, but there seems to be quite a bit of confusion over this point, and not just from me, I've seen a number of posts along these lines... If I call request.getSession(false), the javadocs says of the getSession() method: Returns the current HttpSession associated with this request or, if if there is no current session and create is true, returns a new session. If create is false and the request has no valid HttpSession, this method returns null. But this is not the behavior I'm seeing in my Logon Action... I am in fact NOT getting null back, I am getting a valid session (which no attributesn though). This is in line with what you said, but it seems the javadocs is wrong, and this means that you can never reliably check if a session is null by simply doing session==null, you instead must check if some attribute is present or not to indicate if it's a live session (which is what I was doing previously, I was trying to not do it because it seemed inelegant) because it seems that when a session is invalidated or times out or of course is newly created, the attribute won't be present. Am I missing something, or is the javadocs in fact incorrect here?

Argh, this one is hurting my head... I have an application that starts out by returning index.jsp (it's the welcome file). This JSP opens a new window via JavaScript and loads into it index1.jsp. index1.jsp populates five frames of a frameset. At the end of all this, my logon screen is seen. The important thing to note here is that no Actions are executed to this point, it's just loading JSP's, and there is not really any JSP code in any of these except for a bunch of request.getContextPath() calls. No code accesses session or anything like that, and there are only two references to getting anything out of request (because the logon page might be shown after a bad attempt, and I need to get the userID and password that was attempted). In all of them, I have session=false in the page tag. Now... I've created a SessionListener to tell me when a session is created or destroyed. Problem is, during all these JSP loads, the create event fires TWICE! What's worse, session is NOT null (which I expected it to be), and worse still, I'm getting two DIFFERENT session ID's! It looks like two sessions are being created when it seems like absolutely NONE should be. I'm banging my head against the wall with this one. Anyone have any ideas? Thanks folks!

Hi,
Tomcat-users.xml is a plain file: you can edit it manually or using a

should be within a privileged context (it's a context attribute) and the

Help moving from a ConnectionBroker to using Tomcats DB Connection pool
Hello,
I need a little help
Hopefully I can give the info needed.
My servlets have been using this code I found a long time ago called
DbConnectionBroker
It works very well.
I have been trying to move to the db connection pool of tomcat.
They both use org.gjt.mm.mysql.Driver
But here is where I am having problems. Hopefully this little piece of code
is enough to help
The thing that is different is the connection I get from the
DbConnectionBroker is different that the one I get from
/
//this is what I do to use jndi
ds = (DataSource)ctx.lookup(JNDICONTEXTLOOKUP);
conn = ds.getConnection();
/
So I guess my question is, is someone using JNDI with mysql and getting the
LastInsertID..
When I use the connection broker this piece of code below works fine, but
when I use it with jndi the line long newKey =
((org.gjt.mm.mysql.Statement)stmt).getLastInsertID() ;
Gets a class cast exception
Thanks for any help...
try{
Statement stmt = conn.createStatement();
int ret = stmt.executeUpdate(ustr);
rowsProcessed = ret;
if ( ret == 0 ){
writeErrorInfo(userID,executeSql,
executeSql Failed - non fatal

no rows processed,-1);
stmt.close();

}

RE: Override the system.outs so that no Tomcat Logfile is produced.
Hi, It's possible to redirect System.out/System.err from each webapp to the context's log instead of catalina.out using the Context's swallowOutput attribute. Further, you can add swallowOutput to the DefaultContext element, thereby establishing that for all webapps using one parameter in in server.xml. However, tomcat will still use System.out (which goes to $CATALINA_HOME/logs/catalina.out by default) for some of its own logging: you can configure that further by configuring commons-logging (see the tomcat FAQ entry on configuring tomcat's internal logging). I think even with these configuration entries, however, the catalina.out file will still be touched, so it will be produced although stay at zero size. You can probably avoid even the latter using OS-specific redirection syntax, such as 21 /dev/null or whatever.

Re: Multiple requests sharing the same Servlet instance
Yes, they're true objects. But if you instantiate more than one of them, each will have identical state. While it's possible to have different state to be set depending on different instances based upon the computing environment at the time that the Servlet object is created, I don't see how this type of different state is useful since the developer does not have any control over when Servlets are instantiated. - Original Message - From: QM [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED] Sent: Wednesday, June 16, 2004 8:04 PM Subject: Re: Multiple requests sharing the same Servlet instance On Wed, Jun 16, 2004 at 07:53:07PM +0530, Keith Hankin wrote: : Maybe I'm being dumb, but it seems to me that based upon what I'm hearing, : there is no benefit of doing Servlet instance pooling since the Servlets : aren't true objects; they are merely places to put code, since no local : state is useful. Depends on how you look at it: they are true objects in that they are self-referential, and hold some (shareable) state. Check out the javadoc for the HttpServlet class: by default, the ServletConfig and some other vars are shared, and you're more than welcome to share thread-safe objects (such as a logger). I'd certainly call those local objects useful. =) -QM -- software -- http://www.brandxdev.net tech news -- http://www.RoarNetworX.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Using Tomcat's HTTP processor and SSL
I am considering using Tomcat alone as my HTTP server as well as my servlet container with SSL configured. I know a lot of people use Apache HTTP Server instead of Tomcat for this and Tomcat is just the servlet container only. Is there any reason why I should not use just Tomcat alone for this. I'm actually using JBOSS with Tomcat, but Tomcat still handles the HTTP and servlet requests. I have no static pages at all on my site. Seems like a hassle to configure a separate server (Apache HTTP) when I don't have to. Unless there is a good reason (i.e. performance) to do so. I am using v4.1.28 Thanks for any help or suggestions. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Using Tomcat's HTTP processor and SSL
In what I've read people use Apache+Tomcat because better performance in apache serving static content, and the potential to use PHP served by apache for example. In the case that you only use dinamic java code, it's better because it's easier to mantain one service that two!!! But I'ver read too that performance for SSL is far better in apache so people make the ssl in apache and serve dinamic content with tomcat, but I've no experience (until now) so I'm talking only what I've read... - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Classloading in Tomcat
I have rewritten my earlier question... Hrm if I start tomcat with: c:\java\jdk\bin\java -Djava.endorsed.dirs=c:\java\tomcat\common\endorsed -classpath c:\java\jdk\lib\tools.jar;c:\java\tomcat\bin\bootstrap.jar -Dcatalina.base=c:\java\tomcat -Dcatalina.home=c:\java\tomcat -Djava.io.tmpdir=c:\java\tomcat\temp org.apache.catalina.startup.Bootstrap start It works!!! But if I do it from Eclipse: Main class: org.apache.catalina.startup.Bootstrap Program arguments: start VM arguments: -Djava.endorsed.dirs=c:\java\tomcat\common\endorsed -Dcatalina.base=c:\java\tomcat -Dcatalina.home=c:\java\tomcat -Djava.io.tmpdir=c:\java\tomcat\temp Local directory: C:\Java\tomcat\bin Classpath bootstrap entries: c:\Java\jdk\jre\lib\rt.jar User entries: bootstrap.jar (TOMCAT) and tools.jar (JDK) It starts but it does not find any default jars (like from WEB-INF/lib) unless I put them to class path. What's different in first and second way to start Tomcat? Why the second method doesn't work well? My regards, Vladas
