Re: Intermediate write in JSP
Thanks Michael ...i will try this option.
I have one more issue while looping throught the result set we see the
memory usage increases contineously and then drops (after looping through ~5k)
and then increases again.
Is there any memory managemnt we can do from our side to that it does not
reaches peak limit.
Do I need to run gc after looping for some record set

I am able to overcome server time , once the download is complete I am able

Re: Increase Heapsize
Hi It's an option to the JVM, just append this line over there -verbosegc -XX:+PrintGCDetails. To avoid out of memmory errors just make sure minimum and maximum heap space should be same. You can find out still more information with GC details logged on enabling above option in JVM. Check it out how much memmory is reclaimimg on each GC and whats the frequency of minor or major GC are happening. More over you can set different alogorithms like copying collector.mark and compavt/mark and sweep /incremental/throughput collectors in young/ old generation.

RE: Intermediate write in JSP
Hi,
I had a similar issue in the past that I overcome by having the servlet
start a separate thread that was producing the report,
And a jsp page refreshing every 10 seconds or so checking for completion.

Re: Intermediate write in JSP
I had a similar issue in the past that I overcome by having the servlet start a separate thread that was producing the report, And a jsp page refreshing every 10 seconds or so checking for completion. That is, of course, the asynchronous application design. Sometimes it is necessary, but it does bring a question. What is being so slow? Sending the amount of data you're sending is not slower than it can be. My guess is that DB is taking a rather long time to complete the query. I would not blame the network, because the Net connection between DB and TC should be at least as fast as the one between TC and your client. So, the original poster might wanna take a look at the DB for speeding it up. It might not be possible, though.

SuPHP alternative for JSP and Tomcat
Hello, I am hosting several domains on one server. For security reasons I need JSP scripts to run under different users, to avoid users from one domain rewriting or reading files of another user through JSP scripts . In apache and PHP it's solved by SuPHP module. Is anything similar possible in Tomcat?

New Session Created Randomly in Tomcat 5.0.28
Problem Description : 1. I have a typical JSP-Servlet web application running on tomcat 5.0.28. 2. After successful login a new session is created. (in login.jsp) and user specific data is kept in session 3. User moves on through the application . Accesses a JSP ( e.g. PageWithHeavyJavascript.jsp), JavaScript code. 4. After doing some selections etc. PageWithHeavyJavascript.jsp, user browses another JSP ( e.g. plain.jsp) which *does not* have any session related code. At this point *sometimes* a NEW session is created. (By implementing HttpSessionListener I observed that the sessionCreated() methos is getting called everytime and sessionDestoryed() method is never getting called) 5. After lot of debugging I have observed that this happens when lot of Javascript code is called through clicks etc. new session is created. I am unable to link lot of Javascript calls with New session getting created. I would appreciate if you can shed some light on this issue... any hint/solution? -Nilesh

What I want to do is somehow create a name (I did not purchase another DNS) name yet, and tie the localhost:8080/appname as 1 context. Some dns-like name until I purchase DNS?

I recommend taking a look at the catalina.policy file. You can set all sorts of permissions for tomcat and the individual webapps in the policy (not sure how one would set permissions for individual JSPs though). To enable it add the -security parameter when launching tomcat. Simply enabling the security manager is rather likely to break existing web applications. You will probably have to add the permissions they need to make them usable again.

I believe that the default configuration is to use an AJP13 connector on port 8009, and not an HTTP connector on port 8080. Do you want Apache to handle outside connections to Tomcat? If so, then you should not be trying to connect to your webapp directly on localhost:8080 - you should use mod_jk or mod_proxy_ajp to connect Apache to Tomcat and then hit localhost:80/your-web-app. Hope that helps, -chris signature.asc Description: OpenPGP digital signature

I was wondering if this is just caused by Tomcat closing the socket before the proxy finished reading the message. Is there a way to set the LINGER on these sockets?

If it was the LINGER I would expect that our Java client would have problems too. Still, it is something I can look in to, as I am currently at a loss for any other theories.

When the error occurs, the proxy logs say: Error reading response header. Server closed connection. On a thousand rapid requests from a client thread, I will get this only 0 - 3 times. If I send the response header Connection: close on every request from my servlet, I do not get the error. However, I do not want to disable persistent connections. I did a snoop, and I noticed that the responses I get (on the same socket) a bunch of replies with this header: HTTP/1.1 200 OK Transfer-Encoding: chunked Date: Tue, 18 Jul 2006 19:35:12 GMT Server: Apache-Coyote/1.1 On the last one for a given socket, HTTP/1.1 200 OK Date: Tue, 18 Jul 2006 19:35:12 GMT Server: Apache-Coyote/1.1 Connection: close Any guidance or insight would be greatly appreciated.

RE: The requested resource is not available
Thanks for the response Hassan. But if the above url-pattern is in a Context with path '/abc', then you're telling it to give everything that looks like 'http://localhost:8080/abc/abc' to your control servlet, which probably isn't what you want... :-) No, you are exactly right. This is *not* what I want. I want the servlet to get everything from 'http://localhost:8080/abc'. Would you mind explaining where I went wrong? The Context configuration would be helpful, though. As for Context, I don't have any context information in my web.xml file (I don't believe... at least I have no Context element present in the file). What I posted before was nearly the entire web.xml. I can post the whole file if you'd like.

Re: [OT] Problems with file permissions
We answer all kinds of questions here. Just protocol to mark off topic posts as such. In the Unix environment, the ftp service (not to be confused with the ftp client) can depending on vendor be configured to set permissions as it receives files. I know in ProFTPd, it's set using the umask config setting. Try to find out what ftp service you have on the server and look at it's man pages for info on what config settings are available. Actually, it's not Apache that cares about file permissions, but the OS (unix in this case). Apache may start as root, but it's workers are all spawned as unprivileged users (the user 'apache' in my the case of my server) and the OS will deny access if the apache worker doesn't at minimum have read access. --David [EMAIL PROTECTED] wrote: Hi David, Thanks for that and sorry for my ignorance of Apache Tomcat but I have just moved from an old IIS server that didn't care about the file permissions.

Perhaps some other software you are using is configuring JAXP (that's the stuff in javax.xml.*) to use Xalan, but not providing the library. If that's the case, you can get Xalan from http://xalan.apache.org/. Download it and install the JAR file in your webapp's WEB-INF/lib directory. Good luck, -chris

Ravi, I don't really know enough about the command line to know what you mean by that command, but when I tried copying and pasting it told me '$' not recognized. Oh, sorry about that. The $ is a UNIX thing. Your use of Winzip is just as good. However, I did open up the rt.jar in winzip and I did see some files called XSLT, etc. Is that what you mean? Perhaps. You're looking for the file org/apache/xalan/processor/TransformerFactoryImpl.class inside that JAR file.

Re: out of memory error
Barry, possibly like I (incorrectly, because he was on UNIX) told a guy the other day. Go to startup.bat, right click and change (under the Memory tab) properties in the Initial Environment box from Auto to 4096 or higher. This still isn't going to change anything: Modifying the environment for the startup.bat file doesn't change the memory size for the JVM or the number of threads it is allowed to create. The initial environment size in a windows process is the amount of memory (usually specified in kb) allocated for the environment. That's where DOS stores environment variables like PATH, COMSPEC, PROMPT, etc. You can see what's in the environment by running cmd or command and typing set. Increasing the environment size will not change any of the JVM settings, because the JVM runs in a separate process started by the startup.bat file. The only way to modify the JVM settings is to do one of the following: 1. Modify the catalina.bat file and add your options to the JAVA_OPTS environment variable (you may have to add SET JAVA_OPTS= [insert your java ops here] to the script). 2. Set the JAVA_OPTS from the command line before launching startup.bat. #2 is nice to use because it's easy to test: open a command window (run cmd or command), set the JAVA_OPTS and then run startup.bat. If you run tomcat as a service, it doesn't invoke catalina.bat, so you'll have to read this document: http://tomcat.apache.org/tomcat-5.5-doc/windows-service-howto.html And set the JvmOptions command-line parameter. I've never done this myself, so you might need to get help from someone else if you need it. Also, this document is marked as obsolete, so there may be newer or better documentation out there for running tomcat as a windows service. Not sure why you'd want to run an app server on windoze, though ;) -chris signature.asc Description: OpenPGP digital signature

Re: TransformerFactoryConfigurationError
Ravi, The TransformerFactoryImpl.class is there, but it's path is com/sun/org/apache/xalan/internal/xsltc/trax/ Do you think this is the problem? Probably. There's a system property that dictates which implementations are chosen for SAX and DOM parsers, as well as XSLT processors. It's odd that it's being set to something that is invalid. I don't remember what those system properties are, but you can get the current list at any time by doing this: System.getProperties().list(System.out); This will dump the current system properties to standard output. If you put this into a JSP and hit it with a web browser, it will dump the system properties, and you can check them out. Then, you can see which one is pointing to the wrong XSLT processor and possibly correct it. (Just start Java with -Dthat.system.property=com.sun.org.apache.xalan.internal.trax.TransformerFactoryImpl, or whatever seems most appropriate given the current value of that system property). If you can't find a system property with that (incorrect) class being mentioned, then it's probably some kind (unfortunately) incorrect default value. In that case, you'll have to start looking around on the web for sites that describe how to set the default. Good luck, -chris signature.asc Description: OpenPGP digital signature

RE: Increase Heapsize
From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] OS: Solaris OK. 64 bit OK. 16 GB ram Your server only *has* 16 Gbytes of RAM. If it also has 16 Gbytes of *free* RAM, which is what I asked, then you have an unusually slim version of Solaris ;-). Anyway, given that lot you're tinkering at the edges by allocating a mere gigabyte or so to your JVM. If you have enough RAM and if the JVM running Tomcat is the main application on the system, I'd give it (say) 80% of the free (note *free*, not total) RAM on your system. That gives a couple of gig for unusual overhead such as maintenance scripts. If you're living alongside other applications or database servers, you'll have to size the JVM appropriately. The 64-bit Sun JVMs will quite happily take as much RAM as you throw at them, at least for the next couple of years while memory technology catches up. - Peter - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Database Connection Error Cannot create PoolableConnectionFactory
Hello everyone, Background: I have a newly installed and configured Ubuntu server running Tomcat5.5 and Mysql 5.0. This server was created in an attempt to migrate from a Red Hat server in a similar configuration, running the exact same webapp. Most of the configuration/classpath differences between the two platforms have been ironed out. The Problem: When our webapp trys to connect to the database on localhost, an exception 'java.security.AccessControlException: access denied (java.net.SocketPermission localhost resolve)' is generated. The server.xml configuration is below: Resource name=jdbc/EconDollarsDB auth=Container type=javax.sql.DataSource username=user password=pass driverClassName=com.mysql.jdbc.Driver url=jdbc:mysql://localhost:3306/DBName?autoReconnect=true maxActive=20 maxIdle=5 / I can connect to the database just fine using the command line client and the same username/password combo. This configuration has been working fine for at least a year on the older server. The only similar problems I have found on the net (meaning the same exception is generated) involve applets and attempts to connect to different hosts.

IIS and Tomcat Redirector.
Hello, I am having troubles setting up the Tomcat Redirector (binary version 1.2.15) on Windows 2000 server. Java 1.5_07 is installed, and I am using the base binary installation of Tomcat 5.5.17. After installing the redirector dll, I configured an isapi filter on my web site (not the default web though. That was setup automatically from the install.) Restarted Tomcat, IIS, checked on the ISAPI filter and had the green upward arrow. Went to the /jsp-examples/index.html page, and got an error 404. Curiously on the page it claimed to be powered by Jetty. Jetty is not installed on the server at all, unless it comes as part of JSpell or the redirector dll. The site is password protected, using NTLM After the isapi discovery, there is hexidecimal / ascii dump of the http headers. Any advice would be greatly appreciated. Thank you, Steve.

Re: Increase Heapsize
Ibrahim, The webapp is a content management site which has been producing out of memory errors. Is this your own code, or are you using something off-the-shelf? If this is someone else's product, you may wish to contact them. The server has 16GB RAM which is quite significant. Curious:are there any other adantages to setting them the same? I answered that in my previous message: Upon the recommendation of another poster, you might want to set the initial and the maximum to the same thing (that will allocate the entire Java heap at once, instead of forcing the memory manager to grow the heap during runtime) -chris signature.asc Description: OpenPGP digital signature
Re: TransformerFactoryConfigurationError
Ravi,
Sorry, this is going over my head. Is there a way to look at the system
properties without having to write a JSP?
There is:
public class Env
{
public static void main(String[] args)
{
System.getProperties().list(System.out);
}
}
Unfortunately, you can't run this from within Tomcat without something
like a JSP or servlet (or even a ConcetxtListener) to get it going.
I'm operating under the assumption that there is some other component
that is (possibly incorrectly) setting this default -- that it may not
show itself if you run this short program from the command line.

Re: Database Connection Error Cannot create PoolableConnectionFactory
Cameron, When our webapp trys to connect to the database on localhost, an exception 'java.security.AccessControlException: access denied (java.net.SocketPermission localhost resolve)' In the past, the Connector/J JDBC client would often use localhost.localdomain as the hostname, even though only localhost had been specified. I suspect that was an odd system configuration at work. At any rate, the database has been configured to allow connections from localhost but not localhost.localdomain. I suspect that this is not your problem (given that the error is java.net.SocketPermission localhost resolve), but it might help. Another thing you might want to try is to use the IP address 127.0.0.1 instead of the hostname localhost. Dunno if it will help, though. -chris signature.asc Description: OpenPGP digital signature

Ravi, So... how do I get it to run with a servlet? You would have to create a new class that extends HttpServlet, implement the doGet and/or doPost methods and then put your code into there.

Re: Tomcat 5.5/Axis 1.4 java.lang.reflect.InvocationTargetException
Hi Barry and Tomcat/users/devs,
I am hoping an axis/tomcat/dev/user will have a good advise. I am sure more
than one user has needed to use axis/tomcat and a JNI interface, so I am
sure this has been done. I need classes in the shared context and classes in
the webapps context, which cause serialization/desearialization problems
when making calls among classes between the two contexts.
I write the questions here, in case a reader don't want to go through the
whole explanation below them.
Q1) As long as I do not referece the classes, which I believe means the
classes are not loaded, then there is not problem. When they are accessed,
then it fails. The classes are in both common, shared and webapps, where
else I am supposed to place them?
Q2) How do I turn on Logging at the debug level in Tomcat, or any kind of
meaningful logging to figure out what is happening?
Q3) Is there a way to enable remote debugging using Eclipse? ... I read that
it is possible, but is there any configuration in Tomcat I need to change
and does it include setting a port for it?
I found the log that has the stdout, which was showing a couple of
exceptions, which I solved by placing the appropriate jar files in the right
place. However, the problem didn't go away, there is something in the Tomcat
servlet or axis (I don't know) that is handling an exception in the server
side, because I have a try {} catch () {} where the problem ocurrs and I
don't catch anything, but the exception is returned to the client. Now not
even an exception is thrown to the stdout or staderr files.
The problems comes when in the shared/classes files I access the parameters
that use the classes generated by the WSDL2java tool. Those classes are in
both
TOMCAT_HOME/shared/classes
and
TOMCAT_HOME/webapps/axis/WEB-INF/classes
I also dropped the axis jar files in
TOMCAT_HOME/shared/lib
TOMCAT_HOME/webapp/WEB-INF/lib
TOMCAT_HOME/webapp/axis/WEB-INF/lib
but I still have a problem. At this point it would be nice to at leasts see
the DEBUG output from Tomcat, but I am not sure how to do that or if it is
something related to axis. To make this more explicit, this example works:
class CRLStub
...
public void getCompay(CompanyHolder company, StringHolder result)
throws java.rmi.RemoteException
{
company.value = new soap.xsd.CompanyInfo();
company.value.setCompany(Something);
result.value = ok;
}
Now, if I try to do the following, there is no error, but obviously, the
result is not the same
class CRLStub
...
public void getCompay(CompanyInfoHolder company, StringHolder result)
throws java.rmi.RemoteException
{
jnInSharedContext.getCompany(company, result);
}
class JNIcrlInSharedContext
...
public void getCompany(CompanyInfoHolder company, StringHolder result)
{
/// No problem as long as I don't access neither company or result
}
But if I do this, then I receive the
java.lang.reflect.InvocationTargetException at the client side, even if I
try to catch the exception with a try {} catch () {} pair.
public void getCompany(CompanyInfoHolder company, StringHolder result)
{
company.value = new soap.xsd.CompanyInfo();
}
I would appreciate any kind of hint,
Thanks in advance,
--Luis R.

I realize Tomcat does seem a bit bereft of info in the logs sometime.
Would it have been a case where it printed to the system console instead?
Mine does that sometimes, instead of (or in addition to) the log(s) and I
troubleshoot it that way.

Subject: Re: Tomcat 5.5/Axis 1.4
java.lang.reflect.InvocationTargetException
Hi Shankar,
Thanks a lot. I found my problem. It turned out not to be a Classloader
problem, but a NullPointer (THANKS TO TIM FOR THE HINT :) ) problem in the
server, which I had not found because I don't know how to debug my
application in Tomcat and there is no single log in the Tomcat directory
that can give me a clue of what's happening.
Anyway, the configuration worked as I had it initially:
1) Dropping the axis.jar in the WEB-INF/lib as you pointed out.
2) Stubs/Skeletons and all that had nothing to do with the JNI in
axis/WEB-INF/classes
3) The classes for the JNI interface/loading the jni library under
shared/classes
I think if I can find a way to debug our application in the server, we
could
get better light on what is happening and solve problems a lot quicker :|.
It's like driving blind right now :|.
Anybody knows how to debug remotely axis/tomcat apps?

Re: Database Connection Error Cannot create PoolableConnectionFactory
Thanks for the quick replies. Martin: No luck with your advice. I'm not sure there's a problem with mysql permissions, as I can log in with a mysql client from the local machine and access the database as normal. The original command used to set the permissions was 'GRANT ALL ON DB.* TO 'User'@'%' IDENTIFIED BY 'password';' Christopher: I've tried using the IP address instead, unfortunately that didn't work. Bob: The entry in the hosts file is defined as you said. For some reason tomcat can't connect to the database and create a connection pool, even though a normal client can connect just fine.

Symbolic link for welcome file???
I'm experiencing some strange behavior when setting a symbolic link as a welcome file. In my document root, my index.html is a symbolic link to another file. This link changes depending on the status of our server. When I access the file directly through the browser URL, it functions normally. However, when I attempt to navigate to the directory that contains this symbolic link, it seems to not load the correct version of the file (almost like what it loads has been cached). I have cleared my browser cache and it does not help. Any ideas about this? Thanks, Brad Mann Software Engineer - Information Access Services HARRIS Corporation / GCSD (321) 984-6292

Re: Tomcat - Joram JMS configuration
When starting a new thread (ie sending a message to the list about a new topic) please do not reply to an existing message and change the subject line. To many of the list archiving services and mail clients used by list subscribers this makes your new message appear as part of the old thread. This makes it harder for other users to find relevant information when searching the lists. This is known as thread hijacking and is behaviour that is frowned upon on this list. Frequent offenders will be removed from the list. It should also be noted that many list subscribers automatically ignore any messages that hijack another thread. The correct procedure is to create a new message with a new subject. This will start a new thread.

Tomcat Crashing -- how do I read the resulting hs_err_pid11598.log?
I'm running Fedora Core 3, Tomcat 5.0.30, in a two server environment, where we have an F5 load balancer and are doing session sharing at the Tomcat level. The box has 4GB of RAM on it, and has experienced a memory failure. We tested the physical RAM on the server, and it failed 2 extended memory tests, so we replaced the RAM. We also saw that the swap space was only at 1.5GB, so we upped that to 6.5 GB. Prior to this issue with memory, Tomcat ran just fine without error. Now, Tomcat runs for about 30-45 minutes and crashes. The catalina.out file has this: # # An unexpected error has been detected by HotSpot Virtual Machine: # # SIGSEGV (0xb) at pc=0xb79d032a, pid=11598, tid=1886555056 # # Java VM: Java HotSpot(TM) Server VM (1.5.0_03-b07 mixed mode) # Problematic frame: # V [libjvm.so+0x3b532a] # # An error report file with more information is saved as hs_err_pid11598.log # # If you would like to submit a bug report, please visit: # http://java.sun.com/webapps/bugreport/crash.jsp # so my question is: how do I read/interpret the hs_err_pid11598.log file so I can figure out what is happening here? thanks, Kim :-)

Tomcat, Timer and TimerTask question
Hello
Just trying to schedule a batch email run using Timer and TimerTask framework on
Tomcat 4.1.31
Found the following example from http://www.javapractices.com/Topic54.cjp
Trying trying to test this scheduling mechanism first just by printing to
System.out first... (see below)
It does not seem to run. Code compiles properly in eclipse.
Does tomcat require any libraries... There is no errors in tomcat either.
public final class schedEmailUser extends TimerTask {
public static void main (String[] args) {
TimerTask schedEmail = new schedEmailUser();
Timer timer = new Timer();
Calendar date = Calendar.getInstance();
date.set(Calendar.DAY_OF_WEEK, Calendar.THURSDAY);
date.set(Calendar.HOUR, 12);
date.set(Calendar.MINUTE, 10);
date.set(Calendar.SECOND, 0);
date.set(Calendar.MILLISECOND, 0);
timer.scheduleAtFixedRate(new schedEmailUser(), date.getTime(),
1000 * 60 *
60 * 24);
System.out.println(In main Sending email...);
timer.cancel();
}
public void run(){
System.out.println(In run Sending email...);
}
} //end schedEmailUser

I even wrote a small java program to connect using JDBC, in case that was the problem. I used the same parameters given to tomcat and again, it works just fine.

Re: Increase Heapsize
Hi, Setting heap size to -Xms256 -Xmx1024 will allocate mammory intially to 256 MB and keeps expanding as allocating more objects up to 1024. My recomendation to you is as mentioned in previos mail set heap size to -Xms1536 -Xmx1536 and verify it. But Do not increase heap size blindly to greater values which may lead to performance issue(Pause times may become more to clean GC). try the heap settings and let me know, If still problem is there just send the verbose output and log file.
