What is accepted way to read/write files in Tomcat ?
Hi all, What is the best way to read and write file(the file locations are inside context) in a servlet container. I was able to read file using getResourceAsStream() but writing using URLConnection().getOutputStream() failed and throws protocol doesn't support output - UnknownServiceException. Is it legitimate to use the getRealPath() to get the context root and write the file ? Antony Paul - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Virtual Hosting Revisited - Apache serving static pages..???
John B. Moore said: Thanks for responding.. And yes, I keep hearing that one can do this ... But...G I'm slow I guess, because that still does not give me a hint as to HOW that is to be configured.. Do you have some virtual host directives that do this that I can use as examples.. Maybe my problem is that I am thinking I could have the static pages located under Apache/htdocs and the jsp pages under Tomcat/webapps.. I can't find and example that combines the standard Apache virtual host directives with what is needed to also direct the jsp to Tomcat.. I can easily to each separately, but have yet to find a way to do both Here you go... # External IP Address: xxx.xxx.xxx.xxx VirtualHost 192.168.1.111:80 ServerName test.mydomain.com ServerAdmin [EMAIL PROTECTED] DocumentRoot /var/www/test.mydomain.com ErrorLog /var/log/httpd/test.mydomain.com/error_log CustomLog /var/log/httpd/test.mydomain.com/access_log combined JkMount /someurl/MySpecialServlet worker1 JkMount /admin/* worker1 JkMount /manager/* worker1 JkMount /*.jsp worker1 /VirtualHost Create as many JKMount entries as you need to map all your servlets and JSPs. Whatever doesn't match any of the JkMount entries will be handled by Apache from the document root (/var/www/test.mydomain.com in this example). You can even route the different servlet/jsp requests to different tomcat workers (if that is needed or works for you). Hope that helps.

Do you know how the session is being tracked in the browser? Cookie,

the http traffic?

hi,
Thank you for your reply and suggestion .
I have only one user and one browser window and I get this problem .
I also like to mention that in the starting of the JSP if I added a line

then I don't get this problem at all .But I am not able to understand
why access to the session variable gives exception

Hi,
I have a jsp page which is refreshed atuomatically every 10 seconds.I
get and put values in the session by using the implicit session variable

becomes null and throws a null pointer exception.
I get a null pointer exception and session is printed as null but even
the if block (session == null) is not executed .
I printed the value of request.getSession(false);.This gives me session

During the first few refreshes both have the same value.

JTA support
Hello everybody, I've been going up and down DBCP's (and Tomcat's) homesite and haven't found the answer to this: Does Tomcat support (and manage) JTA? I know there is Tyrex, which provides this support, but I don't want to use it. From what I've read, it's somewhat obsolete, replaced by DBCP. I'm currently using DBCP. On the top of that, from what I've understood from reading Sun's JTA specs (yes, I'm a newbie to JTA), one thing is to provide the JTA connectivity support (which is provided by the JDBC driver), and a different one to support JTA management (this is transaction management and so...), which is responsibility of the container (Servlet container / App. Server). Am I right? Will appreciate any help you can provide. Thanks in advance. Regards, Freddy.
RE: SESSION PROBLEM in UNIX
Hi ,
Thank you for your reply .
I use IE 6 as my browser in windows and tomcat on HP unix.
I meant that ,all I did was open a browser window load my application,
goto a particular page Set page to refresh for every 10 secs(
application had a combo box to set interval of refresh).After few
refresh I get a null pointer exception and realize that the session is
null suddenly .( I repeat I don't get this issue when I run tomcat in
windows)

Re: JTA support
Freddy, IMHO your options in this issue are: 1. Use Tyrex (Dead project, so you're on your own when you run into problems) 2. Use JOTM from Objectweb (that code is not really maintained nor in a good shape either. current project lead agreed on the mailing list, that it's probably a good idea to rewrite and several people who have run into problems have come to the same conclusion) 3. Use JBoss (Almost certainly the best-supported but that means you have to learn how to set up tomcat to run within JBoss, the complexity of which others should judge as I have not tried it) 4. Buy a commercial solution as the one by atomikos (rather strange licensing model IMHO) The right choice depends on what kind of project you do (critical commercial or less critical e.g. university project). I would recommend against 1 which I've been doing myself and it's not really worth the trouble. 2 is rather easy to set up and OK if it works for you (as I mentioned quite a few people including myself have run into some issues but a lot of others as I understand use it in production with success). I guess 3 would probably be the safest route but might be a bit of a learning curve in the beginning. 4 I have not used but if you don't know exactly how many concurrent TXs you will have the license may become very expensive.

RE: JTA support
Hi Robert, Well... eerrrhmmm... let's see: I just downloaded JBoss' latest version. I has already integrated (ready to use) Tomcat 4 (v4.1, if I recall). Then, based on what JBoss claims, I suppose (have not confirmed it, I have to say...) that the JTA management implementation is provided (as specified by Sun's JTA specs) by JBoss. The complementary part is, as you already know, provided (or not) by the JDBC driver you are using. In a few words, I'm trusting JBoss's JTA-ability, not Tomcat's. That said, I can do this for you: (1) Given the fact that I'll be using JBoss + Tomcat 4, just as they are shipped, I'll develop a few JTA test over JBoss. Once I run them all, I can send you my config files (cannot guarantee when I'll finish this, I'm into lots of stuff right now). :) (2) I can give it a look to see if I find something on the Internet (so far, all I've found refers to v4, not v5). Let me know if there is something else I can do for you.

RE: Load balancing with apache2, mod_jk2 tomcat 5.0
Yes. I did a full stop and start of apache. There are no errors in the log
files either. Do you, or anyone else, have a workers2.properties file of a
working system that you are willing to share? I've gone through all the
sections and properties in the latest jakarta jk2 document as well as other
How-Tos and don't see what I've missed (I'm afraid I don't understand all of it
either :). Does the shm section play a part? I interpretted it to be needed
only if one wants to share session data between the differnet tomcat servers,
and does not have anything to do with load balancing.

Subject: Load balancing with apache2, mod_jk2 tomcat 5.0
Hi,
I have set up four tomcat 5.0 servers for load balancing using an apache2
server and mod_jk2 on RedHat 9.0. The trouble that I am having is that
most
of
the user sessions are routed to only one of the tomcat servers even though
the
lb_factor for all is the same, 10. All tomcat servers seem to be working
since
I can disable all but one in the workers2.properties file to force that
tomcat
server to be used. Chnaging the lb_factor can also cause a different
tomcat
server to be used most of the time, but I haven't figured out how to
control
the balancing by lb_factor.
Below is the workers2.properties file that I am using.

Is it legitimate depends on who you talk to. ;) Purists (I don't mean that negatively) would remind you that the only 'guaranteed' filepath available is the javax.servlet.context.tempdir .

This also were i got the version 1.50 that i
alluded
to in an earlier email.
from what i can see. IN the 1.50 version. there has
been a change made to the getURL(File file)
function:
/**
* Get URL.
*/
protected URL getURL(File file)
throws MalformedURLException {
File realFile = file;
try {
realFile = realFile.getCanonicalFile();
} catch (IOException e) {
// Ignore
}
//return new URL(file: +
realFile.getPath());
URLEncoder urlEncoder = new URLEncoder();
urlEncoder.addSafeCharacter(',');
urlEncoder.addSafeCharacter(':');
urlEncoder.addSafeCharacter('-');

urlEncoder.addSafeCharacter('\'');
urlEncoder.addSafeCharacter('(');
urlEncoder.addSafeCharacter(')');
return new
URL(urlEncoder.encode(realFile.toURL().toString()));
}
In the tomcat 5.0.22 version, it appears that the
getURL(File) still looks as it did before markt
made
his feb 22 fix to the bug.
It appears that the fix is in the tomcat 4.0 branch
but not in the tomcat 5.0 branchs. I hope i am
reading
the cvs repositories correctly. If not perhaps you
can
help me. Basially I'm looking for a build of tomcat
(perferably a 4.0 build) that has this fix. I am
reluctant to build the tomcat source files myself
and
distribute a custom bug fixed version of tomcat to
our
customers.
I'm running into a problem without this fix because
i'm attempting to make an RMI call from with in
tomcat. When tomcat attempts to resolve the remove
interface i get an exception like:
java.rmi.UnmarshalException: error unmarshalling
arguments; nested exception is:
java.net.MalformedURLException: no protocol:
Files/Apache
I belive that this is cause WebAppClassLoader
getURL(File) function is suffering from a bug
encoding
problem in the jdk.
http://developer.java.sun.com/developer/bugParade/bugs/4273532.html
I belive that Apache has recognized this problem
and
has implemented its fix in its cvs repositories in
its
tomcat 4.0 branch, but no in any of the builds on
the
4.0 branch.
Please advice...

We've also had 2 people developing it on XP and Win2k pro for the year without seeing this. Has anyone else had any problems with threads locking?

jsessionid parameter not being accepted
I have done my own url re-writing manually to cater for those browsers who have turned off cookies. i.e. I have manually added ?jsessionid=session id parameter to every url. This worked well in Jrun, but Tomcat is not accepting the jsessionid parameter, and is creating a new session each time. The tomcat session manager is the default one, in fact there is no session manager visibly enabled in server.xml, so everything is default. Has anybody got any ideas what is going on and what I should do? Regards, Malcolm Warren - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Tomcat 5 : DEBUG level
I think you need to setup a logger, if using java1.4
then just use built in java.util.logging.Logger, otherwise
maybe log4j, prob best to create a file logger and log ALL
webapp spcefic messages to it
here is mine if you need something to start, its a singleton
so you'd typically invoke with
cdmanager.CdManagerLogger.getInstance().logp(
Level.FINE,
this.getClass().getName(),
yourMethodName,
your output message);
===
package cdmanager;
import java.util.logging.Logger;
import java.util.logging.Level;
import java.util.logging.FileHandler;
public class CdManagerLogger
{
protected static java.util.logging.Logger logger = null;
private CdManagerLogger()
{
if(logger==null)
{
// Initalize the instance of the class
logger = java.util.logging.Logger.getLogger();
try
{
FileHandler fh = new
FileHandler(D:\\JBuilder9\\myprojects\\cdmanager\\logs\\cdmanager.log);
fh.setFormatter(new java.util.logging.SimpleFormatter());
// Send logger output to our FileHandler.
logger.addHandler(fh);
logger.setLevel(java.util.logging.Level.ALL);
}
catch(Exception e) { e.printStackTrace(); }
}
}
static public java.util.logging.Logger getInstance()
{
if(logger!=null)
return logger;
else
{
new CdManagerLogger();
return logger;

Hi,
I have set up four tomcat 5.0 servers for load balancing using an
apache2
server and mod_jk2 on RedHat 9.0. The trouble that I am having is that
most
of
the user sessions are routed to only one of the tomcat servers even

the
lb_factor for all is the same, 10. All tomcat servers seem to be
working
since
I can disable all but one in the workers2.properties file to force that
tomcat
server to be used. Chnaging the lb_factor can also cause a different
tomcat
server to be used most of the time, but I haven't figured out how to
control
the balancing by lb_factor.
Below is the workers2.properties file that I am using.

It works alright, but we've had so many more lock-ups than we used to. So I decide to try Standalone SSL on tomcat4. That didn't work since I'm using IBM 1.4 and tomcat4's code imports the wrong packages for SSLSocket in com.sun.net or something instead of javax.security... I think.

Memory Leak

However, the memory in the task manager keeps going up. For example right now it is at 717,000 K, even though the heap used is at about 200,000 K. What am I missing here?

RE: Memory Leak
In your profiler rather than looking at the type of object taking the memory look at the accumulated memory consumed by your classes.

From your description it is not shure that you have a memory leak at all. The vm is not returning free memory to the os.

Re: What is accepted way to read/write files in Tomcat ?
Some thoughts on this matter :-) If I am not wrong, the servlet specification states that the directory pointed by javax.servlet.context.tempdir can be cleaned on restart (it is left to the container implementation). I think Tomcat does not do such a cleaning, but other containers (or even future Tomcat versions) are perfectly allowed to do so :-S So, sticking to the specification, I guess the only way left to define such a location is specifying it through JNDI. This means that any webapp needing (for example) to work as file server are unnecessary difficult to implement. Having to implement a custom servlet that does the same as the default one, but accessing another directory out of the context, sounds to me like reinventing the wheel :-D Having war deployments this lack of functionality, it has always seemed strange to me that the specification only considers mandatory this type of deployment. Rodrigo Ruiz Mike Curwen wrote: Is it legitimate depends on who you talk to. ;) Purists (I don't mean that negatively) would remind you that the only 'guaranteed' filepath available is the javax.servlet.context.tempdir . And getRealPath() would blow up on you, if you were running your webapp from a WAR file. However, if *you* know that your app will only ever be used unpacked, then fully document this requirement, and go ahead and use getRealPath(). -Original Message- From: Antony Paul [mailto:[EMAIL PROTECTED] Sent: Thursday, April 15, 2004 12:28 AM To: Tomcat Users List Subject: What is accepted way to read/write files in Tomcat ?

Tomcat 4 session replication in a production environment
Hi, Is anyone using Tomcat 4 session replication in a production environment, if so, could you please share your experiences ? Unfortunately we are unable to upgrade to TC 5 for now but I need to setup session replication for some of our TC 4 servers for fail-over purposes (we have HW load balancers for load balancing). I have successfully set it up in our stage environment to prove it is viable but I am interested in others experiences. Also, is it possible for me to create a new replication jar for TC 4 which incorporates the bug fixes done on the TC 5 branch ? Thanks, Ryan. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
difference in jsp:usebean between tomcat 4 and 5
Hi, I've noticed a change in the java code that results from a
jsp:usebean when upgrading from tomcat 4 to tomcat 5.
I'm wondering if this is a change in the spec or just a coding
difference between versions:
*This jsp:*
jsp:useBean id=payment class=mybeans.ValidateableBean
scope=session /
*Results in this java code: *
*on tomcat-5.0.19:*
mybeans.ValidateableBean payment = null;
synchronized (session) {
payment = (mybeans.ValidateableBean)
_jspx_page_context.getAttribute(payment, PageContext.SESSION_SCOPE);
if (payment == null){
payment = new mybeans.ValidateableBean();
_jspx_page_context.setAttribute(payment, payment,
PageContext.SESSION_SCOPE);
}
}
*in tomcat-4.1.27 (same on tomcat-4.1.30 I believe):*
mybeans.ValidateableBean payment = null;
synchronized (session) {
payment = (mybeans.ValidateableBean)
pageContext.getAttribute(payment, PageContext.SESSION_SCOPE);
if (payment == null){
try {
payment = (mybeans.ValidateableBean)
java.beans.Beans.instantiate(this.getClass().getClassLoader(),
mybeans.ValidateableBean);
} catch (ClassNotFoundException exc) {
throw new InstantiationException(exc.getMessage());
} catch (Exception exc) {
throw new ServletException(Cannot create bean of class +
mybeans.ValidateableBean, exc);
}
pageContext.setAttribute(payment, payment,
PageContext.SESSION_SCOPE);
}
}
Was this a 'performance enhancement'? The problem I have with the tomcat
5 code is that it doesn't catch errors. ValidateableBean just happened
to be an abstract class with multiple ValidateableBean subclasses. The
section of code that this is in had an if statement around it that made
sure that the 'payment' variable shouldn't have been null, and that it
was already an instance of a ValidateableBean subclass, so the code
would have just called pageContext.getAttribute and have been done.
Tomcat 4 was fine with the abstract class because when it compiled it
never tried validate the call to 'new mybeans.ValidateableBean()'
Tomcat 5 throws an error that an abstract class can't be instantiated
(which is true, but why does is the compiler now forced to perform this
check?)

Extending GenericPrincipal/RealmBase: Essentially a classloader question
HI all, He have implemented our own realm and principal buy extending org.apache.catalina.realm.RealmBase and GenericPrincipal. (Using TC5.0.19 on Solaris and Windows. Realm defined in Context.) By doing this, however, we've got ourselves into sort of a catch 22 in terms of classloading. Hopefully someone can offer some assistance. I've referenced the Class Loader HOW-TO at http://jakarta.apache.org/tomcat/tomcat-5.0-doc/class-loader-howto.html, so I'll use it's terminology. RealmBase and GenericPrincipal are located in catalina.jar, which resides physically in server/lib. The howo defines this jar as in the Catalina class loader. The definition says that the Catalina classes are totally invisible to web applications, which seems true enough. In order to extend these, I must locate my jar in server/lib. So far so good. The problem is that I need to use my extension of GenericPrincipal within my webapps. I tried moving my jar to common/lib, since, according to the parent tree in the howto, it is visible to both the Catalina branch and the webapp branch. Doing this causes a NoClassDefFoundError for GenericPrincipal. Apparently since the Catalina classloader is below the common classloader, it can't find GenericPrincipal. The only solution that appears to work is moving the entire contents of server/lib to common/lib, essentially 'promoting' all of the classes normally in the Catalina class loader to the common class loader. Is this the best solution? It seems to me that I should be able to extend RealmBase/GenericPrincipal without having to move jars around. Any ideas? John
quick question when getting started
I'm upgrading from Tomcat 4 to 5 and I just installed Tomcat 5 on a dev machine to play with it, and I know a couple things are organized a bit differently, but the provided index page is weirding me out. I tried to add a line of text to the index.jsp in webapps\ROOT and when I reload the page (that I browse to by going to localhost on my Win 2K Server machine), that line of text isn't appearing. I've tried adding other bits, too, and I've tried restarting Tomcat, and I found a catalina-root.jar in the WEB-INF\lib folder and deleted that in an effort to get it to recompile the index.jsp, but nothing seems to be working! Why? Here's an example of what I've modified in the HTML: pcenterbIf you're seeing this page via a web browser, it means Stephen has setup Tomcat successfully. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Extending GenericPrincipal/RealmBase: Essentially a classloader question
Can your webapps see GenericPrincipal? Looking at the JavaDocs for the Catalina api, it looks like the session façade your get app gets is going to have access to a java.security.Principal (likely also a façade), not a GenericPrincipal. Maybe instead of extending a class in the server/Catalina classloader, you could implement another subclass of java.security.Principal, and have that class loaded in the common classloader.
