Re: Question on debuggin JNDI/prepared statement in a bean
Hello
pstmt.setString(1,ClassifiedAd);
pstmt.setString(2,UniqueDateId);
Are those two parameters - 'ClassifiedAd' and 'UniqueDateId' - variables?
They should be, and if so, where do you declare and initialise them? They do
not appear in the method you posted.

I am frustrated trying to debug a prepared statement within a bean; what
am I doing wrong?; ANY clues appreciated
It is not throwing any exceptions yet I methodically went over the code;
granted this is the first time I used beans versus servlets.
Can anyone point me to a good example (JNDI, JSP, JavaBean, Resultset)
Code within bean:
private void prepareStatement(){
try{
Context env = (Context) new
InitialContext().lookup(java:comp/env);
pool = (DataSource) env.lookup(jdbc/myDB);
if (pool == null)
throw new NamingException(`jdbc/ myDB ' is an
unknown DataSource);
//dbConnection = null;
dbConnection = pool.getConnection();
String SQLCmd =
select * from AdInfoView where Classification = ?
+ and UniqueDateId ? order by UniqueDateId
desc;
pstmt = dbConnection.prepareStatement(SQLCmd);
// TEST Exception thrown here.
//pstmt.setString(1,searchWord);
pstmt.setString(1,ClassifiedAd);
pstmt.setString(2,UniqueDateId);
}catch(Exception e){
System.err.println(Problem preparing statement +
e.getMessage() + e.getCause());
}
}

Re: Problem in Tomcat 5.0.19 - Help Needed
Hi, Is menus-taglib.tld is your own custom tag, or is it a third party tag. In tomcat 5, tag pooling is enabled by default. This is a feature, where the same instance of the tag will be used in all places. Your tags should be able to handle tag pooling or you must disable it. You can disable it by setting the enablePooling variable to false, in the jsp servlet of web.xml present in tomcat home/conf directory. servlet servlet-namejsp/servlet-name servlet-classorg.apache.jasper.servlet.JspServlet/servlet-class init-param param-namefork/param-name param-valuefalse/param-value /init-param init-param param-namexpoweredBy/param-name param-valuefalse/param-value /init-param *init-param param-nameenablePooling/param-name param-valuefalse/param-value /init-param* load-on-startup3/load-on-startup /servlet -Shan- Ramachandran wrote: Hi Shanmugam, Yes i am using custom tag(menus-taglib) menu here.

How to increate maxThread attribute value?
Hi folk I'm using Tomcat 4.1.27. My web application ,at one point of time does some 2000 database inserts. I have no plm when the no of insert operations to the DB is less (about 100). When the no of inserts exceeds, it shows the following error in the Tomcat server console: Thread pool - All threads are busy,waiting.Please increase maxThreads or check the Servlet status 75 75. So I did edit the server.xml file's tag: !-- Define a non-SSL Coyote HTTP/1.1 Connector on port 8080 -- Connector port=8080 maxThreads=1000 enableLookups=false redirectPort=8443 acceptCount=100 debug=0 connectionTimeout=2 disableUploadTimeout=true / But , I still get the same error Please tell me what is the maximum value I can give for maxThread attribute? Or How can I correct this plm? Thankx in advance Latha - Do you Yahoo!? Yahoo! Finance Tax Center - File online. File on time.

RE: Tomcat 3.2.3 windows service
You can try looking in your wrapper.properties file. At the bottom the wrapper.cmd_line property is defined. This property contains the command line used to fire up Tomcat. Create a batch file containing this command line with all substitutions manually resolved. If done correctly, then this batch file should fail to start Tomcat for the same reason that the service is failing. Hopefully that will make it easier to spot the problem. If the batch file happens to succeed, then you need to investigate the user account being used to start the service. It may be lacking some needed permissions.

Problem with Apache 2.* + tomcat 4.1.* using mod_jk2
hi guys, I am trying to hook up my tomcat 4.1.29 with the Apache 2.0.49 server (running mod_ssl if that makes any difference) with the mod_jk2 2.0.2 version. I downloaded the mod_jk2 source and built it on my own for linux. Everything works fine - I can get to tomcat JSPs and Servlets (using struts in tomcat by the way). But what I notice is if the response is larger than 8K, the mod_jk2 connector in apache is logging an error and throwing away the response on the floor. This is what I see in the apache error log: [Fri Mar 26 01:05:41 2004] [error] msgAjp.receive(): Incoming message is too big 8196 [Fri Mar 26 01:05:41 2004] [error] channelSocket.receive(): Bad header [Fri Mar 26 01:05:41 2004] [error] workerEnv.processCallbacks() Error reading reply [Fri Mar 26 01:05:41 2004] [error] ajp13.service() ajpGetReply unrecoverable error 12 [Fri Mar 26 01:05:41 2004] [error] ajp13.service() Error forwarding ajp13:localhost:8009 0 1 [Fri Mar 26 01:05:41 2004] [notice] ajp13.done() close endpoint ajp13:localhost:8009 error_state 1 [Fri Mar 26 01:05:41 2004] [error] mod_jk.handler() Error connecting to tomcat 12 Any ideas on what I might be doing wrong ?

I am frustrated trying to debug a prepared statement within a bean;
what
am I doing wrong?; ANY clues appreciatedS
It is not throwing any exceptions yet I methodically went over the
code;
granted this is the first time I used beans versus servlets.
Can anyone point me to a good example (JNDI, JSP, JavaBean,
Resultset)
Code within bean:
private void prepareStatement(){
try{
Context env = (Context) new
InitialContext().lookup(java:comp/env);
pool = (DataSource) env.lookup(jdbc/myDB);
if (pool == null)
throw new NamingException(`jdbc/ myDB ' is an
unknown DataSource);
//dbConnection = null;
dbConnection = pool.getConnection();
String SQLCmd =
select * from AdInfoView where Classification =
?
+ and UniqueDateId ? order by UniqueDateId
desc;
pstmt = dbConnection.prepareStatement(SQLCmd);
// TEST Exception thrown here.
//pstmt.setString(1,searchWord);
pstmt.setString(1,ClassifiedAd);
pstmt.setString(2,UniqueDateId);
}catch(Exception e){
System.err.println(Problem preparing statement +

RE: RE: Tomcat Hangs
Hi, Yes this time it appears to be a crash. The message that I posted below is the only message that I can see on the console. This is the last message before crashing. There should be a file called hs_err_ ( can be a number of different things on the Windows platform) in the current working directory of the JVM when it crashed. Look for that file and post its contents if you find it.

RE: Question on debuggin JNDI/prepared statement in a bean
Harry,
Yes the ClassifiedAd and UniqueDateId are two parameters taken
from an html form, the values of ClassifiedAd and UniqueDateId are used
in a prepared statement for substitution of ? and ? the results are then
forwarded to a results jsp, which used the getXXX() to retrieve the
values from the bean.
I have this code working in another form as a Servlet using JNDI
and prepared statements. In the servlet the JNDI connection is made in
the init(blah, blah) and calls the super.init(config) which I
super.init(config) is implicit from reading the Tomcat docs.
The bottom line on this, is how do you set up a JNDI connection
in a bean, use a prepared statement (in a bean), retrieve a resultset
and forward the result for the results jsp to retrieve the value from
the bean.
Finally, I apologize to those who feel this is off topic. I have similar
code working in Resin but for the life of me, I can't get it working
with Tomcat 5 :-( I searched all the archives and can't find a good
example for doing this.
TIA Tom K.

Hello
pstmt.setString(1,ClassifiedAd);
pstmt.setString(2,UniqueDateId);
Are those two parameters - 'ClassifiedAd' and 'UniqueDateId' -
variables?
They should be, and if so, where do you declare and initialise them?
They do
not appear in the method you posted.
Harry
I am frustrated trying to debug a prepared statement within a bean;
what
am I doing wrong?; ANY clues appreciated
It is not throwing any exceptions yet I methodically went over the
code;
granted this is the first time I used beans versus servlets.
Can anyone point me to a good example (JNDI, JSP, JavaBean, Resultset)
Code within bean:
private void prepareStatement(){
try{
Context env = (Context) new
InitialContext().lookup(java:comp/env);
pool = (DataSource) env.lookup(jdbc/myDB);
if (pool == null)
throw new NamingException(`jdbc/ myDB ' is an
unknown DataSource);
//dbConnection = null;
dbConnection = pool.getConnection();
String SQLCmd =
select * from AdInfoView where Classification = ?
+ and UniqueDateId ? order by UniqueDateId
desc;
pstmt = dbConnection.prepareStatement(SQLCmd);
// TEST Exception thrown here.
//pstmt.setString(1,searchWord);
pstmt.setString(1,ClassifiedAd);
pstmt.setString(2,UniqueDateId);
}catch(Exception e){
System.err.println(Problem preparing statement +
e.getMessage() + e.getCause());
}
}

new apache to tomcat connector for linux
Hi, I spend about half a day looking for the jk flavor of the week. It seems the documentation is running in circles. I currently use apache 2 with tomcat 3. (tomcat 3 is the only tomcat that we have been succesfull at installing with apache) I would like to use the new tomcat with apache but the jk for linux download directory is empty. I'm comfortable with the install of apache and tomcat but I can't find any good documentation on getting the jk directory under tomcat5-- conf. About the best I could do is copy my jk directory from the old tomcat to the new. Start the new tomcat server and Apache. Tomcat does get the servlet requests but says the servlet cannot be found. I don't like this hack though and was wondering if anyone else has experienced this confusion. If so could you point to the correct jk and connection methodology? Thanks, Mark

Re: Securing a folder
If you are using JK to connect Apache and Tomcat, you can specify JkMounts which should cause Apache to forward the request to tomcat to handle. For example: VirtualHost 192.168.1.10:80 ServerName www.domain.com ServerAdmin [EMAIL PROTECTED] DocumentRoot /var/www/www.beanpix.com ErrorLog /var/log/httpd/www.domain.com/error_log CustomLog /var/log/httpd/www.domain.com/access_log combined JkMount /pdfs/* worker JkMount /*.jsp worker /VirtualHost should cause any URL with the pattern /pdfs/* and *.jsp to be processed by tomcat. Whether you do this in the main section of the httpd.conf or for a virtual host only is up to you and your configuration. Also consider not having the location of the pdf's within the Apache web root, but instead only accessible by Tomcat... You can then enforce security using a filter, or using some other method. Hope that helps John Sidney-Woollett Dean Searle said: Hello Everyone, Not to sure how to phrase this but here I go anyways. I am attempting to secure a folder that is located within my application. This folder contains pdf's that only need to be accessible by tomcat, the site requires a password to enter. At first if I did www.domain.com/pdfs/somefile.pdf it would open up somefile.pdf. So I tried this in my http.conf file for the website: Location /pdfs order deny,allow deny from all allow from 127.0.0.1 /Location But now tomcat cannot even retrieve the pdf's. Am I doing this right. Could you please point me to some doc's that might explain this more.

Re: TC V4.1.29 Coyote Connector / minProcessors maxProcessors / Confusion
Shapira, Yoav writes: I think your testing, servlets, configuration is all fine. The maxProcessors-1 observation is something I've noticed in the past, but as you say I don't think many people care because they deal with ~75 maxProcessors (the default value). Thanks - glad to know I'm not off in the weeds on that... The second observation: two requests to the same servlet always handled serially. Tomcat normally creates one instance of a servlet for every declaration in web.xml. The exception is SingleThreadModel (deprecated, don't use this) servlets. There's no provision in tomcat to create more instances as the load on the server increases (maybe there is such a provision and I've missed it?). Instead, the processing threads should call the servlet methods in parallel. I'm not sure why you're not seeing this behavior, perhaps someone else could comment, as I have to run to a meeting ;) Yoav Shapira Yes - All you mentioned per Servlet spec expected behavior - why I was surprised at what I was seeing.

Re: Question on debuggin JNDI/prepared statement in a bean
Hey Tom,
When I said your thread was off-topic I didn't mean to imply you couldn't
post your question! Sorry if that's how it came across. Just thought you
should mark it [OT] as Yoav pointed out. It appears I was wrong anyways; I
missed the part about it working in Resin and not in Tomcat.
As for your question, what is it exactly that goes wrong with your app now
that its running under Tomcat and not Resin? Trouble getting the data to
your jsp? Is it not starting up? The code you posted doesn't actually DO
anything so I'm guessing that's just an example you put together to
illustrate what you're trying to do?
Could you post the parts of your Context regarding the jndi resource you are
configuring?

Harry,
Yes the ClassifiedAd and UniqueDateId are two parameters taken
from an html form, the values of ClassifiedAd and UniqueDateId are used
in a prepared statement for substitution of ? and ? the results are then
forwarded to a results jsp, which used the getXXX() to retrieve the
values from the bean.
I have this code working in another form as a Servlet using JNDI
and prepared statements. In the servlet the JNDI connection is made in
the init(blah, blah) and calls the super.init(config) which I
super.init(config) is implicit from reading the Tomcat docs.
The bottom line on this, is how do you set up a JNDI connection
in a bean, use a prepared statement (in a bean), retrieve a resultset
and forward the result for the results jsp to retrieve the value from
the bean.
Finally, I apologize to those who feel this is off topic. I have similar
code working in Resin but for the life of me, I can't get it working
with Tomcat 5 :-( I searched all the archives and can't find a good
example for doing this.

I am frustrated trying to debug a prepared statement within a bean;
what

It is not throwing any exceptions yet I methodically went over the

Can anyone point me to a good example (JNDI, JSP, JavaBean, Resultset)
Code within bean:
private void prepareStatement(){
try{
Context env = (Context) new
InitialContext().lookup(java:comp/env);
pool = (DataSource) env.lookup(jdbc/myDB);
if (pool == null)
throw new NamingException(`jdbc/ myDB ' is an
unknown DataSource);
//dbConnection = null;
dbConnection = pool.getConnection();
String SQLCmd =
select * from AdInfoView where Classification = ?
+ and UniqueDateId ? order by UniqueDateId
desc;
pstmt = dbConnection.prepareStatement(SQLCmd);
// TEST Exception thrown here.
//pstmt.setString(1,searchWord);
pstmt.setString(1,ClassifiedAd);
pstmt.setString(2,UniqueDateId);
}catch(Exception e){
System.err.println(Problem preparing statement +

Re: Question on debuggin JNDI/prepared statement in a bean
Hi Tom how do you set up a JNDI connection in a bean? Exactly the same way as you would anywhere else, so if you have some code working in a servlet, copy it. To be precise, it is a database connection, acquired from a DataSource, which is itself acquired via a JNDI lookup. The fact that your code is in a bean makes no difference. how do you... use a prepared statement (in a bean) Same as anywhere else. how do you... retrieve a resultset, and forward the result Again, same as anywhere else. BTW - you should not be passing about references to JDBC objects that are tethered (so to speak) to database connections - it is bad practice, and likely to cause connection (and memory) leaks. The best thing to do with database connections is, grab your data, store it in some collection object, and then make damn sure you close the db connection - usually within a 'finally' block which is guaranteed to execute, even when exceptions occur. Having stored the data you need in a collection object, you can pass that about as much as you like. That has not really answered your original question, but unless you provide us with all your relevant code we probably cannot solve the problem. Since you got it working before, I would be inclined to start again, making sure that you copy the same JNDI/connection procedures in your 'bean' as in the servlet that works. The fact that your 'bean' is not throwing any exceptions suggests, to me, that there is a bug (logic error) in your code. Starting over might sort that out. Sprinkle about a few (temporary) 'System.out.println' statements to see where your code gets to. Not cool, but they do the job sometimes! If you are using an IDE - like Eclipse - you can run in debug mode, so it's easy to see what is happening - though may be not with JSPs. Good luck.

RE: Session sharing/load balancing multiple tomcat instances W/O Apache Web Server
That doesn't exactly accomplish what I'm looking to do. Like I said, I need session replication amongst the tomcat instances...I guess theres always the idea of managing session data in some other medium (DB). Coincidentally, I just got that working -- but it required a full day of writing code to get around bugs in PersistentValve (I'm going to describe this soon). So unless you want to hack Tomcat, I would suggest avoiding session replication via DB right now (with coding changes it does seem to work great). - tony - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Using PersistentValve for session replication
I want to store session information in a database to be shared between a set of servers in a load balancing without session affinity configuration. Lacking input from others, I will answer part of my own question to possibly help somebody else. The result is that with a day of work it is possible to use PersistentValve and PersistentManager to produce load balancing without session affinity -- but you have to overcome some Tomcat issues in the code along the way. My assumption is while the code is there, it has not been use seriously and therefore is not shaken down. I found and fixed (or worked around) a couple of Tomcat bugs along the way. If a Tomcat developer is interested in these, I would be glad to give more details: * JDBCStore read and writes the database multiple times in load() and save().

Re: TC V4.1.29 Coyote Connector / minProcessors maxProcessors / Confusion
The second observation: two requests to the same servlet always handled serially. Tomcat normally creates one instance of a servlet for every declaration in web.xml. The exception is SingleThreadModel (deprecated, don't use this) servlets. There's no provision in tomcat to create more instances as the load on the server increases (maybe there is such a provision and I've missed it?). Instead, the processing threads should call the servlet methods in parallel. I'm not sure why you're not seeing this behavior, perhaps someone else could comment, as I have to run to a meeting ;) Yoav Shapira Yes - All you mentioned per Servlet spec expected behavior - why I was surprised at what I was seeing. I have additional qualification data but believe I should post under a new thread / subject appropriate. -Jim Layer- egg-on-face update: Wasn't controlling my variables closely enough. Weird non-concurrent behavior I observed was confined to brower-based tests.

application-managed security with tomcat
Hi there,
we adressing the following problem with tomcat (similar works with bea8.1)
using application-managed security
application is sending 401, see *.jsp
private static void login(HttpServletResponse response)
{
System.out.println(sending 401 for authenticate);
HttpServletResponse _tmp = response;
response.setStatus(401);
response.setHeader(WWW-Authenticate, BASIC realm=\Hey, first
identify\);
}
There are no entries in any *.xml about the above realm, instead we are just
waiting for the input from the dialog box and the application should verifiy
this internally against LDAP.
But we are getting no dialog box asking for credentials, instead we get
immediately the default 401 error page in german
html
head
titleError Page 401 - Unauthorized/title
/head
body
font face=Arial,Helvetica,sans-serif
center
h1Sie sind aufgrund fehlender Authorisierung nicht berechtigt,
diese Seite aufzurufen!/h1
/center
/font
/body
/html
So I would need a cookboot how to setup application-managed security, which
means, that tomcat must ignore the realm in the header and just give the
credentials to the application and wait what's happening.
Any help is highly appreciated, Thomas

Re: Session sharing/load balancing multiple tomcat instances W/O Apache Web Server
Jeremy Nix wrote: I've misphrased. What documentation I've come across indicates that Apache (or IIS) is necessary to configure tomcat as a cluster. It very well may be possible, which is why I'm asking the list. The main feature that I'm looking for in this configuration is the session failover ability. I have a hardware load-balancer, so load-balancing is not exactly what I was looking for...just the session sharing. Does your hardware load balancer support sticky sessions? If it does, you can use Tomcat's HTTP connector, and configure your balancer as if Tomcat were a web server (which it is, when you use that connector). If it doesn't I personally recommend getting one that does ;-) or using Apache + mod_jk / mod_jk2. Use the hardware balancer and 2 Apache for high availability. Other than that, there is in-memory or JDBC session clustering (uncomment two elements from your server.xml, and you are mostly done). That implies that objects stored in sessions need to be Serializable. Performance impact will depend on your webapp design, so YMMV. I only tried in-memory a few months ago, and performance dropped seriously, but it worked without problem. Most likely our webapp's fault. You may encounter issues with frames and similar constructs.

Simpler solution to force login on conditional security restraint?
Is there a simple way to force a standard login programmatically on page/servlet? I would like to conditionally force the behavior that happens non-conditionally when a user requests a page which has a security constraint and gets their login. I can think of some solutions for this, like setting up some data in a session redirecting to a page with a declared security restraint and redirecting them back. But it seems like I must be overlooking something simpler. Like maybe throw a particular exception that the container responds to like it had a security restraint. The container already handles these kinds of events and gets the login and returns to the appropriate page remembering everything it needs to, so it seems like I should be able to just trigger such an event and let the container handle it rather than duplicating some of that functionality. -Steve - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Question on debuggin JNDI/prepared statement in a bean
Tom In a servlet you have an init() statement that executes only once which you get your db connection in... I hope you are not in a fog about this: there is nothing pre-ordained about getting a connection in a servlet init method - that just happens to be where your code is. also you need to call super.init(config), where you don't have to do this in a bean, because it is implicit... Hmm... I think maybe you are in a bit of fog about all this :-) Calling 'super.init( config )' within a servlet's init method has nothing to do with database connections. Anyway, if you are prepared to post the *exact* bean code that is not working for you, I am prepared to look at it and try to help you. Posting snippets of code is not good enough. The alternative is for you to walk through your code (with println statements, or a debugger) and see where it stops working. Next challenge is I have a blob that I set and get, but when I get the blob on my results page, it comes up with... Is that the servlet providing the 'results' - or did you fix the bean? Regards Harry Not exactly...it is not the same! I have it working with a connection pool, mySQL and JNDI. To keep my reply short it goes like this within the bean: getDBConnection(); // get the connection prepareStatement(); // prepare the statement rs = pstmt.executeQuery();// execute the query and of course after that I get my parameters. In a servlet you have an init() statement that executes only once which you get your db connection in, also you need to call super.init(config), where you don't have to do this in a bean, because it is implicit. (By the way, if someone wants an example, I will post it, but you'll then be my wife.) Next challenge is I have a blob that I set and get, but when I get the blob on my results page, it comes up with something like this @1eb2473 which I assume is an address. Anyone know what know how to get, what's in the address. Maybe open a stream?

Exactly the same way as you would anywhere else, so if you have some code working in a servlet, copy it. To be precise, it is a database connection, acquired from a DataSource, which is itself acquired via a JNDI lookup. The fact that your code is in a bean makes no difference. how do you... use a prepared statement (in a bean) Same as anywhere else. how do you... retrieve a resultset, and forward the result Again, same as anywhere else. BTW - you should not be passing about references to JDBC objects that are tethered (so to speak) to database connections - it is bad practice, and likely to cause connection (and memory) leaks. The best thing to do with database connections is, grab your data, store it in some collection object, and then make damn sure you close the db connection - usually within a 'finally' block which is guaranteed to execute, even when exceptions occur. Having stored the data you need in a collection object, you can pass that about as much as you like. That has not really answered your original question, but unless you provide us with all your relevant code we probably cannot solve the problem. Since you got it working before, I would be inclined to start again, making sure that you copy the same JNDI/connection procedures in your 'bean' as in the servlet that works. The fact that your 'bean' is not throwing any exceptions suggests, to me, that there is a bug (logic error) in your code. Starting over might sort that out. Sprinkle about a few (temporary) 'System.out.println' statements to see where your code gets to. Not cool, but they do the job sometimes! If you are using an IDE - like Eclipse - you can run in debug mode, so it's easy to see what is happening - though may be not with JSPs. Good luck. Harry Harry, Yes the ClassifiedAd and UniqueDateId are two parameters taken from an html form, the values of ClassifiedAd and UniqueDateId are used in a prepared statement for substitution of ? and ? the results are then forwarded to a results jsp, which used the getXXX() to retrieve the values from the bean. I have this code working in another form as a Servlet using JNDI and prepared statements. In the servlet the JNDI connection is made in the init(blah, blah) and calls the super.init(config) which I super.init(config) is implicit from reading the Tomcat docs. The bottom line on this, is how do you set up a JNDI connection in a bean, use a prepared statement (in a bean), retrieve a resultset and forward the result for the results jsp to retrieve the value from the bean. Finally, I apologize to those who feel this is
JK2
Hi I really wanted to avoid asing the list for this again. Sorry, I couldn't get it going. This was on the list soo often and I always read the posts and I bookmarkes, every link I could find. I am using apache2 and tomcat5 for some time now. Every works great. Now I need to run multiple tomcats and I don't want to get more ips right now. So I took a few days (yes, it took that long for me) and compiled mod_jk2. Now I am stuck with configuration. The online documentation really isnt useful. Sorry. This differs from tomcat. Anyway, I stored a lot of bookmarks in the last weeks about JK2 from this list. But there are a lot of questions open. Some tutorials talk about default workers2.properties files. I dont know where to find this. A lot of tutorials about jk2 give different syntax for the configuration files. NO tutorial even states where the files must be placed. Can anyone tell me, how tomcat should know where to find these files? Or apache2? So my questions are: - Does someone have a [jk2-] beginners tutorial, that covers details? - Can anyone with a working environment send me his configuraiton files for apache, tomcat, workers, jk2? I will handle them secretly and you can remove any real domainnames beforehand. I would be very thankful.

Tomcat5 and HttpServletRequest#getSession
Hello All, I'm a little confused about the creation of new sessions. I have a webapp running (Tomcat 5.0.19), and I can see from a SessionListener that the session is timed out - Session destroyed, all attributes removed. So far, so good. But when a subsequent request is made like the following excerpt from a JSP page: %= request.getSession(false)% I would have expected to get null as the response, instead I get a non-null session object (e.g. [EMAIL PROTECTED]) and the SessionListener reports that a new session was indeed created at the time of the JSP request. So, it seems to me that a session is always created when the getSession() method is called regardless of the boolean parameter. Can someone clarify for me?

I would rather use a stateless session bean and use httpsession for persisting my conversational state.

My design requirement requires a SFSB and I need servlets to invoke my SFSB. I will also need to cluster the TC5 servers. Passing the reference within the servlet and between method calls is the only way to hold a handle and interact with a single instance of a SFSB. If I use a JBOSS 3.2.3 server which comes bundled with TC then JBOSS takes care of my httpSession sharing between the various JBOSS servers in the cluster. (JBOSS has a different mechanism for httpSession sharing). But I would like to have a multitier cluster with seperate TC clusters and seperate JBOSS clusters.

I don't think this is a sensible idea, and I'm not sure it's even allowed. I would advise you not to store remote references inside your session objects. Try storing just the current 'state' inside the session. Use a ServiceLocator to get an instance of the session bean each time you need it, using the current session to populate the state.

Re: RE: Tomcat Hangs
It appears that upgrade to JDK 1.4.2 is helping. Tomcat did not crash/hang today. - SPS - Original Message - From: Shapira, Yoav [EMAIL PROTECTED] Date: Friday, March 26, 2004 9:17 am Subject: RE: Tomcat Hangs Hi, You said it's hung, not crashed, but this is an internal crash. It's a bit beyond not responding ;) Due cose: update your JDK if you can, as 1.4.2 is far more stable and performant than 1.3. And make sure you have all the Windows Update patches installed on the machine, as this error is usually due to a miscommunication between the JDK and the OS. Was there a stack trace that you cut off in the message below?

Any thoughts? - SPS - Original Message - From: Surya Suravarapu [EMAIL PROTECTED] Date: Thursday, March 25, 2004 7:50 pm Subject: Tomcat Hangs We have Tomcat 4.1.27 running in conjunction with Apache 1.3.x. We're using AJP13 connector. The machine that we're using has got over 2GB of Memory and good processor speed. Tomcat has been allocated 1 GB of max memory. The issue is: For every two hours or so Tomcat hangs. That means, Tomcat don't crash but simply don't accept any more connections. While using Tomcat with Apache we're getting 500 Internal Server Error. We are constantly restarting server to make it work. There is no good information in the logs that could lead us to debug this issue. I have tried several things. Taken out Apache and Connectors from the equation by running Tomcat as standalone. This time Tomcat we get server not found error - Page cannot be displayed message. I have also increased the maxProcessors of the connector to 300 instead of the default 75. Interesting thing is -- when Tomcat hangs the memory usage never reaches even half of the max memory (1 GB) allocated to Tomcat, and the number of threads that we see is also always less than half of maxProcessors value (300) set. If anybody encountered this kind of issue or if you have any thoughts please respond.

Message on Tomcat console
Hello All!
Tomcat console is displaying the following message very often:
---
SystemId Unknown; Line 1358; Column 31; name has an illegal attribute:
{1}
---
It is not affecting Tomcat performance or anything but just want to
find out if anybody else have observed this kind of behavior. Somebody
on the net was suggesting that it could be related with xalan.jar?
Thanks!

Re: Tomcat 4.1.27 fails to start
sarcasm I'm going to go out on a limb here and suggest that perhaps you have some xml that you just edited where you included the string -- within a comment block. I'm basing this guess on the error message that you got: The string -- is not permitted within comments. /sarcasm Seriously, check the XML that you just edited and look for something that looks like: !-- This is my comment -- it's not well-formed. -- Such a comment is malformed. If you can't figure out which xml it is (you should be able to), look at the source Catalina.java:449. Next time, you may want to consider thinking about the error message you got before posting to the list and, if you're going to post, give some context and an indication that you did so: I was trying to edit my server.xml to add a new Coyote Connector, which I believe I did correctly. Now when I start my Tomcat with the startup.bat file, I get the following error message: [Stack Trace]. I couldn't figure out what was causing this, so I bumped up the debug level, but didn't see anything. [Debug output]. I googled for is not permitted within comments but didn't find anything useful. I'm offering 40 karma points for anyone who can help me with this... please. ;) justin At 06:40 PM 3/26/2004, you wrote: Tomcat fails to start with the following stacktrace: - Catalina.start: org.xml.sax.SAXException: Stopping after fatal error: The string -- is not permitted within comments. org.xml.sax.SAXException: Stopping after fatal error: The string -- is not per mitted within comments. at org.apache.xerces.framework.XMLParser.reportError (XMLParser.java:1228 ) at org.apache.xerces.framework.XMLDocumentScanner.reportFatalXMLError(XM LDocumentScanner.java:570) at org.apache.xerces.framework.XMLDocumentScanner.scanComment (XMLDocumen tScanner.java:1894) at org.apache.xerces.framework.XMLDocumentScanner$ContentDispatcher.disp atch(XMLDocumentScanner.java:1121) at org.apache.xerces.framework.XMLDocumentScanner.parseSome (XMLDocumentS canner.java:381) at org.apache.xerces.framework.XMLParser.parse (XMLParser.java:1081) at org.apache.commons.digester.Digester.parse (Digester.java:1548) at org.apache.catalina.startup.Catalina.start(Catalina.java:449) at org.apache.catalina.startup.Catalina.execute (Catalina.java:400) at org.apache.catalina.startup.Catalina.process (Catalina.java:180) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke (NativeMethodAccessorImpl. java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke (DelegatingMethodAcces sorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.apache.catalina.startup.Bootstrap.main (Bootstrap.java:203) -- We're using Tomcat 4.1.27, JDK 1.4.2 on Windows 2000 machine.
