RE: Database connections aren't being released...

RE: Flexible way of defining application variables in text format?
I use a properties file stored in the WEB-INF directory. Modifying the
web.xml is too error prone. Using another XML file is a lot harder than a
properties file. Just use the servlet context getResourceAsStream(), and
pass that to the properties.load() method.

RE: Order of WebApp Loading
Its not deterministic. Save yourself a lot of time, and don't complain about it and ask it to be changed. You need to re-think your logic so there is not a dependency. A pretty obvious solution would be to have either application check to see if the database is started, and if not start the database.

RE: The process tomcat {pid 1488.0000 } is leaking handles
I have a web application that I host for our customers. Right now we are
running about 60 virtual hosts with tens of thousands of hits per day. I've
also run stress tests using Jmeter where literally millions of requests are
generated. I have never observed a resource leak.
This is a common topic in the forum. In almost every instance, it is the
application that is leaking resources.
Developers should run findbugs:
http://findbugs.sourceforge.net/
And PMD
http://pmd.sourceforge.net
To scan their applications for resource leaks.

The context name and the file name have to match exactly.
Also, root contexts need to have a path of "".

RE: Advice for Hosting Many Individual Webapps?
The technique I use is this: Run the HTTP connector on port 8080. Forward port 80 to port 8080. To re-start the system: edit the server.xml and run the HTTP connector on port 7080 Change the shutdown port to 8006 Start tomcat, and wait till it comes up. Re-run the firewall script to forward port 80 to port 7080. Stop the instance running on port 7080. The downside is that any active sessions get bounced and have to re-login.

RE: virtual host memory usage
The obvious first guess is that you have a class that is in the host classloader, and not the common classloader, and that class is consuming large amounts of memory.

RE: Tomcat and the HttpServletRequest Object
Even if I were to write this as an enhancement, I can tell you from past
experience it would be rejected out of hand by the committers.
In your particular case, the tool you were using before used something like
a Vector or ArrayList to hold the parameter name/value pairs. Tomcat is
almost certainly using a HashMap of some sort. Any deterministic
implementation is going to be slower than the current random access
implementation. Committers will savage any submission that appears slower
and the person submitting it. No thanks, I'm not going there.
Even if Tomcat were to work in the manner desired, there's nothing that says
that every browser is going to submit the form elements in their order of
definition. You really need to abandon this idea and make your application
more robust.
You remind me of people who do SQL database development. They don't specify
an ORDER BY clause on their statements, but it always came back in the order
they wanted. Then one day, they upgraded versions of the database or the
query optimizer decided to take a different path, and all of a sudden the
results are coming out of order. Much wailing and attempted reporting of
bugs ensues... The truth is in SQL, that if you don't specify an ORDER BY
clause, the database can return the results in any order it likes.
Taking advantage of an implementation specific behavior is natural, but it
can lead (as you have found out) to non-portable code. The final arbiter is
the specification, and if the specification doesn't describe the behavior,
you can't say anything about it.

RE: tomcat and active directory
In order to query the LDAP tree, you have to bind to it. Binding requires
that anonymous bind be enabled, or that you bind with a user id and
password. This is just how LDAP works.
The information that I sent you was information I learned while creating an
LDAP authentication module for our software.

RE: tomcat and active directory
It looks like you are configured for anonymous bind.
By default, the AD LDAP implementation does not allow anonymous bind. You
have two ways of handling this:
1. Configure your AD tree to allow anonymous bind. Essentially, you will
need to create an ACL against the appropriate object (container) in the
tree.
2. Create a low powered user that has read access to the directory tree
and configure the realm to bind as that user..

RE: Virtual host, routing, problems with localhost
I think that unless you have a default entry, that it would fail. The issue is that the host name is being presented to Tomcat, and the request mapper is looking up the host name presented as part of the http request. If it's not found, and there is no default, then it would return an error.

RE: HTTP/1.1 GZIP compression and its impact on server
Yes. In my particular case, the server throughput in requests fell by 2.3%. Of course, the bandwidth utilization fell also from 6Mb/s to 1.0Mb/s. Additionally, you have to ask yourself how much more responsive the application will seem to users. We host our web calendar application, and we run compression on it. Actually, at the co-location site we are moving to, we pay for bandwidth usage. It's probably going to be cheaper to put another machine in than to use 6 times more bandwidth.

RE: HTTP/1.1 GZIP compression and its impact on server
Our App does GZIP compression. I actually did some real testing on using it. Here's what we tell our customers: Enable GZIP Compression Enabling this option will cause Connect Daily to send web pages to the browser compressed in the GZIP format. This can result in a compression factor of six (6) times. Needless to say, this can make your calendar noticeably faster to end users. Our testing indicates serviced per minute was reduced by 2.3% when GZIP compression is enabled.

RE: Poor Performance Tomcat5.5.7, Apache2.0.52, Solaris 9
It's almost certainly your application. I would start with findbugs http://findbugs.sourceforge.net/ And if it doesn't help you sort it out, look at an application profiler. I run about 40 virtual hosts, with a fairly complex calendar app, that gets 10s of thousands of hits per day, on a PIII 500, and the utilization is around 5-10% during the day.

RE: Wild Card Hosting
Right now I'm running tomcat with 40 some virtual hosts without using
Apache. Throwing in the additional configuration/complication issue of
dealing with Apache isn't my preferred route.
It would be a lot simpler to add regex support to the aliases function of
tomcat.
If worst comes to worse, I'll just make an alias for the various hosts. It's
probably going to top at at around 6-10 anyway.

RE: Wild Card Hosting
That doesn't do what I need. I have a very large, existing application that
needs to pick up a parameter based on which host name is used. Changing the
path structure will be hopelessly complicated.
The issue of getting the DNS wild-carding to work is the client's issue.

Wild Card Hosting
Does anyone know if Tomcat supports Wild card hosting? Can I specify a pattern say *.domain.com And have all requests get forwarded to a specific host? Making the host the default host is not an option, because there is already another default host that is used.

RE: tomcat freezes when accessing db after several queries
Look for something like this:
Try {

} catch (SQLException se){
}
Make sure that the catch has:
conn.rollback();
In JDBC, a failed update leaves the underlying record locked until it is
rolled back.

RE: Date parsing
Well because of the ambiguities you have to have some expectation of what
format the date will be in.
What date is 05/12/2005? In the US its May 12th. In Britain it's December
5th. You have to have some expectation and validate against it.
The software is designed to use a Locale as an aid to parsing to set up the
expectation. In our software, we use the browser's accept-language to
retreive a locale.
The class as designed doesn't handle times. It's strictly a date class. Im
thinking about writing a date/time class, but haven't yet.

RE: Date parsing
I wrote my own date handling class, and it will do what you are looking for:
Essentially, to provide a picture for the users you pass in the locale to
SaneDate.getDateFormat().
To parse the date,
try {
new SaneDate(request.getParameter("parm"),lc);
} catch (InvalidDateException ide) {
}

RE: Question for Tomcat Developers - How to Plug In Encryption for JDBC passwords
Your argument about short duration attacks is optimistic at best. Most systems are so poorly secured and monitored, that breakins aren't detected anywhere near that quickly. Let's face reality here. The only safe way to hide the JDBC information is to have the SECRET (encryption password) not available on the server. Any other method is not secure, it is just obfuscation. The tomcat developers quite rightly are refusing to implement any kind of scheme that isn't correct. Look at the startup sequence for Apache using SSL certificates. You have to type in the password for the private key. If you really want to do this, then you will need to have your application startup have a method that permits an operator to enter in the password for the JDBC information at startup. This means that every time your application is re-started, an operator will have to re-enter the information before the application can run. I'd really suggest you purchase and read Bruce Schneir's book Applied Cryptography. Plan on spending a several evenings with it. Just for grins, here's a link to a Javadoc for a crypto system that I designed for a shopping cart. The overriding design goal was to ensure that credit card data would not be revealed even if the database were compromised. I don't see any shortcomings in it, but I haven't opened it up to public review before. http://www.mhsoftware.com/~gsexton/Crypto.html George Sexton MH Software, Inc. http://www.mhsoftware.com/ Voice: 303 438 9585 > -Original Message- > From: Edmon Begoli [mailto:[EMAIL PROTECTED] > Sent: Sunday, February 27, 2005 1:15 AM > To: Tomcat Users List > Subject: Re: Question for Tomcat Developers - How to Plug In > Encryption for JDBC passwords > > > Please do not start the flame war.

RE: Running heavily loaded tomcat sites.
You are really just starting document the issues necessary for running a high volume site. The URL http://www.mhsoftware.com/resources/top10asp.html Has some things that are IIS specific, but also apply to Tomcat applications: Specifically: Store as little as possible on the session. I'm working on an app right now, where the author decided storing the db connection on the session was the way to go. Watch contention. Use an automated code analysis tool like PMD or Findbugs to eliminate bad and redundant code. PMD will detect things like string concatenation in loops, using string concatenation in StringBuffer.append() methods, and other non-optimal techniques. Stress test using a tool like Jmeter.

RE: [OT]web development fee
I've got a package I plan on releasing under a BSD license. It needs some work, but it's pretty close. The only remaining major task is to port the reports from an old proprietary reporting application to Datavision. If you want to see a sample, go to: http://www.stargateschool.org/sgstore/ The sample is not quite in production, so if you want to try it out, use a Visa Card # of 4111 (4 followed by 15 1's). I'd appreciate any feedback. In many ways, it's very cool. Formats for the items are stored as HTML, and parsed out. Products can belong to multiple categories, and shopping by Manufacturer is supported. It does inventory, removing items from the store when the quantity on hand drops to 0. It also supports quantity pricing schedules as well as SKU Variants (vary on size, or color but not both). Support for Accessory SKU's that can be shown in the checkout or cart review screens. Orders are delivered to the fulfillment person via FAX, PDF or Encrypted PDF. A CC of the PDF without the card data can also be sent to an additional person. It should be portable across PostgreSQL, SQL Server, Oracle, Sybase, and DB2, but I've only tested PostgreSQL and SQL Server so far. I'll be the first to admit it could use some more features.

RE: Tomcat JRE vs JDK Issue
One aside, the script (batch file) has an exit statement on the case where the JDK is not detected. This results in a mysterious window closing which causes a lot of hair pulling.

RE: missing resource bundle shouldn't be
Different class loader. The JSP's are running in a class-loader with the
application, while the common/lib jars are in a different class-loader where
the WEB-INF/classes are not part of the search path.

ISAPI and SSI w/ IIS
I have been playing with trying to server side include a URL that is in a context handled by the ISAPI redirector. This is on Windows Server 2003 with isapi_redirector2.dll version 2.0.4. The chain is something like this: URL /calendar/OutputCurrentWeek.html is in a context handled by the ISAPI Filter. Directly invoking this URL produces output. Attempting to invoke the URL via SSI as shown below fails: I'm pretty sure that what is happening is the SSI handler is not passing the request through the ISAPI filter chain. I also tried something like: And The last two trys generated 500 errors. Does anyone have any ideas on how I can do a server side include to a context URL? As a fallback, I can use some code to invoke the URL using a Microsoft.XMLHTTP control, and retrieving the body text. Any ideas are appreciated.

Both are supposed to work. However, that implies several things: - Your session must contain Seralizable objects only. - Your performance will be worse (how much worse highly depends on the size of the objects in your session) And... nobody guarantees that your memory leak (if there is one) is not related to the information stored in sessions. Depending on your load balancer, there is another option (IMHO, better for your case). There are some load balancers that allow you to turn a server down while keeping it up for currently established sessions, for a certain time. That allows you NOT to use session replication, thus not replicating any instability related to sessions.

RE: Help tomcat problem with memory
Why don't you find someone who understands memory usage for your operating system and have them explain the output of your commands to you. You have 700+MB being used as file cache. Your system is under no memory pressure. Your app is slow because 1) It's compiling JSPs, and this takes some overhead on the first hit. OR 2) You are hitting a database and not using connection pooling. This can kill performance. OR 3) Your application is badly written. -Original Message- From: software [mailto:[EMAIL PROTECTED] Sent: Friday, February 27, 2004 1:35 PM To: Tomcat Users List Subject: Re: Help tomcat problem with memory If i have only two java proccess of 141 MB and 55 MB why my memory is over 90% of the utilization and the application working slowly or not working, when the users try to get access using the webserver in this server. i can't understand this problem...thnaks Thanks a lot for you help Fabian software wrote: > Hi this the statemens that i posted in the catalina.sh file > JAVA_HOME=/usr/java/j2sdk1.4.0 ; export JAVA_HOME > CATALINA_HOME=/usr/local/tomcat1 ; export CATALINA_HOME > JAVA_OPST="-server -Xms30m -Xmx40m -Dfile.encoding=ISO-8859-1" > CATALINA_OPTS="-Xms30m -Xmx40m" > > This the output of the top command and both tomcats has been installed > in the same server > > 1:22pm up 21 days, 5:36, 6 users, load average: 0.17, 0.23, 0.28 > 220 processes: 218 sleeping, 2 running, 0 zombie, 0 stopped > CPU0 states: 9.5% user, 4.0% system, 0.0% nice, 85.5% idle > CPU1 states: 7.4% user, 8.5% system, 0.4% nice, 83.3% idle > Mem: 1030580K av, 1019220K used, 11360K free, 0K shrd, > 92348K buff > Swap: 2096376K av, 58748K used, 2037628K free > 706776K cached > > PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND > 23447 root 25 0 86252 84M 18864 S 0.0 8.3 0:02 java > 23461 root 15 0 86252 84M 18864 S 0.0 8.3 0:00 java > 23462 root 15 0 86252 84M 18864 S 0.0 8.3 0:03 java > 23463 root 15 0 86252 84M 18864 S 0.0 8.3 0:00 java > 23464 root 15 0 86252 84M 18864 S 0.0 8.3 0:00 java > 23474 root 15 0 86252 84M 18864 S 0.5 8.3 0:03 java > 23475 root 20 0 86252 84M 18864 S 0.0 8.3 0:00 java > 23476 root 20 0 86252 84M 18864 S 0.0 8.3 0:00 java > > > Ralph Einfeldt wrote: > >> To what value did you set -Xms, -Xmm ? >> Can you post the statement that sets the values ? >> (Have seen to much typos in the past) >> How much memory has your box ? >> >> What says the cpu load ? >> >> Can you post the head of the top output >> hat shows the overall memory usage ? >> >> Are both tomcat instances on the same server ? >> >> Unless you have less than ~150 MB RAM I wouldn't expect that the >> memory usage is the problem if >> each tomcat has it's own server, if they share the same server the >> box would need rougly 300 MB (Depending on how much memory is used by >> other processes) >> >> Remember that all threads of the same vm share their memory. >> >> >> >>> -Original Message- >>> From: software [mailto:[EMAIL PROTECTED] >>> Sent: Friday, February 27, 2004 6:07 PM >>> To: Tomcat Users List >>> Subject: Re: Help tomcat problem with memory >>> Importance: High >>> >>> >>> Yes i've configured the Tomcat environment -Xms, -Xmm but i think it >>> doesn't work, because it's consume the server memory until 145 Mb >>> per process i need to limit the number of java proccess and the >>> memory that they consume on my Linux Red Hat 7.3 server >>> >>> thanks a lot >>> fabian >>> >>> Ralph Einfeldt wrote: >>> >>> >> >> >> - >> 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] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Yet another OT question.
Complain to the list maintainers or check your own MUA for a spurious REPLY-TO header. The message comes in with two reply-to headers and my MUA is just honoring them when I hit reply: There are two cases going on here. The first is that you have invalid SQL. You might be able to catch this by using a prepared statement rather than a statement. In my experience, the preparation of the statement will throw an error. In the second case, if you really need notification about whether the insert failed because the record existed, you need to create a stored procedure and send back a result from it. The result will have to be in the form of a record set (or if Oracle supports it, an OUTPUT variable). This has the unfortunate side effect of increased overhead to handle the result set. I think the problem is that the executeUpdate() method was intentionally designed to be light-weight and you are trying to use it in a situation where you need more functionality.

I have a couple of functions on my site that rely heavily on transactions. To do a simple load test, I picked the function that hits the database the most and opened that same page in two different browser windows. I hit the submit button at roughly the same time, and waited. It appeared that both browser windows stalled. I looked at the processes in SQL Server (2000) and it said that all of the processes for the app were sleeping, and the two being used were sitting on insert statements for the same table (database deadlock?). I let both browsers sit trying to load for a lot longer than it should have taken for the page to finish, then just closed the windows. After that, the site was no longer accessible. The only way to get it working again was to restart the Tomcat service.

What would an ideal server be to handle that type of userbase? Right now it's running on a 1ghz celeron with I believe 512mb of ram running linux. Do any hosting companies offer reasonably priced colocation or flexible accounts with tomcat, php, and mysql installed?

Does anyone here offer services such as using SSH to install Tomcat remotely? We would be willing to pay for someone to install Tomcat in a short timeframe. The ideal person would be someone that knows Tomcat installation quite well. We have installed it on a couple boxes, but usually by a lot of trial and error. We would like to get it up and running properly very quickly. If anyone is interested, please send me an email and I can send you the details.

RE: How is catch{} code handled
If you are really wedded to this architecture (and it's not really that
bad) then a good approach could be something like:
Public class myServlet extends HttpServlet {
doGet(HttpServletRequest req, HttpServletResponse res) {
try {
// All servlet code happens between this try catch pair.
//
// Beginning of servlet
MyClass.invokeSubRoutine();
// End of Servlet
} catch (ProcessingInterruptedException PIE){
return;
} finally {
}
}
}
Public class MyClass {
public static int invokeSubRoutine()
throws ProcessingInterruptedException {
ProcessingInterruptedException pieThrow=null;
try {
// Some JDBC Code
} catch (SQLException se) {
// Log it
// Send Redirect
pieThrow=new ProcessingInterruptedException();
// Alternatively
throw new ProcessingInterruptedException();
}
if (pieThrow!=null){
throw pieThrow;
}
return retVal;
}
}
This code is somewhat cleaner because it forces the caller to handle the
exception. In general, the idea behind exceptions is that nobody checks
return codes so let's use the compiler to force them to catch an error.

George,

Yes, that's very clear at this point. :-)
I understand that the sendRedirect() does NOT terminate the execution
flow that it is in. That's why I follow each one with a return.
However, I think I now recognize my problem.
In my mind, I've always associated a catch{} with an exception and
nothing "escapes" from the exception. And that's true, assuming you did
NOT do what I did and disolve the exception into a simple message that
displayed as text on a JSP page. As I now see, in THAT case, the
catch{} DOES return, thereby allowing multiple sendRedirect()s to
occurs.
Thank you for setting my thinking straight.

RE: How is catch{} code handled
Unfortunately, your logic is flawed.
The major flaw is that sendRedirect() does not terminate processing of
the servlet. IOW, this is happening:
Servlet Invoked
Sub-Routine Invoked
SQLException Generated
Exception Caught
Send-Redirect to Error Handler
exit Sub-Routine Via Return
More code executed
Send-Redirect() Issued -> Throws IllegalStateException
Essentially, because you are not checking the return state from your
sub-routine, you are having a problem. You need to return some sort of
value from the sub-routine that indicates processing should stop.

Subject: How is catch{} code handled
My sudden IllegalStateException problem turned out to be caused by my
error handling technique, but I'm not sure why.
When I started this project (as a way or learning JSP), I have
EVERYTHING in JSP pages, meaning that there was a lot of Java code in <%
... %> sections of the JSP page. I added an errorPage declaration to
each of my JSP pages to divert all errors to my standard error handling
page--and all was well.
Later, I decided to limit the JSP pages to HTML as much as possible and
move all of the Java program logic into servlets. I left the errorPage
declarations in the JSP pages, although there wasn't much left there to
throw an exception.
In the servlets, I used the standard try/catch constructs to intercept
exceptions. However, I decided I wanted the exceptions caught in
servlets to be handled by the same error page as the JSP pages used.
Rather than have EVERY catch{} clause do the redirect, I defined a
utility subroutine named errorPage() that collected various information
in the catch{} clause, then called sendRedirect() to the error page.
Separate from these catch{} clauses, whenever the processing in a
servlet was complete, it ended with a sendRedirect() to the next JSP
page followed immediately by a return. I had assumed that the
sendRedirect()s in the main servlet code were "safe" from the
sendRedirect() in the catch{} cause since--as I understood it--once the
exception was thrown and the catch{} entered, nothing else in the
servlet was processed.
However, my "IllegalStateException" experience suggests there is
something going on with catch{} that I don't understand. Or, as a
friend of mine used to say, "I don't understand all I know about that."
:-)
To recap, I got an IllegalStateExceptioni pointing to a sendRedirect()
in a servlet until I effectively removed the sendRedirect() by returning
before the sendRedirect() could be reached. Only then did I see an
SQLException intercepted by a catch{} and redirected with
sendRedirect() to the error page.
Why did main servlet processing appear to continue (allowing the second
sendRedirect() to cause a problem) after the exception was triggered?

RE: Memory comsuption
I don't understand why you think you have a problem. You have a machine with 2GB of memory installed. 84MB is free RAM, and the OS is using 330MB of ram for cache buffers. Tomcat is using some 50MB of RAM. The machine is clearly not under any kind of memory stress FWIW, the memory options are case sensitive, and I think you need a capital M at the end. Although, why you would want to limit RAM consumption to 1GB, when you are complaining about tomcat using 50MB is quite beyond me.

RE: RES: TCP-FIN problem
Just one little detail with setContentLength(). If you are writing a
string out, make really sure that your content length is correct. If it
is not, the connection will stay open.
A common mistake (at least one I have made) is to think that the
character count in a buffer is the number of bytes in the content.
Depending upon your character set, this may not be true. If you are
using UTF-8, accented characters are almost certainly being written as
two bytes.

Maybe with a little bit more detail:
Application Code:

Reciever = new
InputStreamReader(ClientSocket.getInputStream());
} catch (UnknownHostException e) {
System.err.println("Unknown host: " +

String Message = new String(Method + " " + File +"

Sender.write(Message,0,Message.length());

try {

XMLBuffer.append((char)c);

Servlet code could look like this

}catch(Exception e){
getLogger().writeToLog("Database Read Statement Error:

response.getWriter().print(Data);
response.setContentLength(Data.toString().length());

Hope this makes all a little bit clearer!

Subject: A weird issue
Hello All,
Now my software platform as below:
Windows 2000
JDK1.4.1_02
Tomcat 4.1.24
Sql Server 2000
I have a piece of code as below:
private String jdbcDriverClass="sun.jdbc.odbc.JdbcOdbcDriver";
private String jdbcURL="jdbc:odbc:cfdata";
private String jdbcUserName="sss";
private String jdbcPassword="sss";
try {
Class.forName(jdbcDriverClass);
con=DriverManager.getConnection(jdbcURL, jdbcUserName,
jdbcPassword);
stmt=con.createStatement();
} catch (SQLException se) {
throw new RuntimeException("A database error occured. "
+ se.getMessage());
try{
String sqls="select CID from CF_GDW_Load";
rs=stmt.executeQuery(sqls);
}
This piece of code is run in tomcat. It will extract data from table in
Sql Server 2000. In Sql Server 2000, the table is named as CF_GDW_LOAD,
but in the code I write it as CF_GDW_Load. I know that itis not case
sensitive in Sql Server, but when I run this piece code in Tomcat, an
exception occurs. it says that [Microsoft][ODBC SQL Server Driver][SQL
Server]Invalid object name 'CF_GDW_Load'. If I change CF_GDW_Load to
CF_GDW_LOAD in the code, no exception occurs. So in here it is case
sensitive. But making me surprised is that on the same software
platform, I run another piece of code in Tomcat, it extract data from a
table in another database in Sql Server 2000, it is not case sensitive.
Do you have any idea about the weird issue? Thanks.

Xiaojing

RE: web administration tool and tomcat-users.xml
There is a real, bigger problem. Without looking at the source, my guess is that the parameters are not being parsed correctly and they are being treated as ISO-8859-1 and not UTF-8. This can happen when there is a mismatch between the character encoding sent from the browser, and the encoding used by the application. The real solution would be to make sure that the application is using the right character encoding. Maybe one of the committers can find this. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Monday, December 15, 2003 6:45 AM To: [EMAIL PROTECTED] Subject: web administration tool and tomcat-users.xml user administration with the "Tomcat Web Server Administration Tool" (/admin) a) umlauts No umlauts are supported.

RE: Installing Manager tool
Did you set the "privileged="true" " attribute in the context definition? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Monday, December 08, 2003 2:44 AM To: [EMAIL PROTECTED] Subject: Installing Manager tool Hi, I installed Tomcat 4.1 to test the Manager interface. I followed the manual step (add a user in the tomcat-users.xml file, add context ...). I use the default port and when I enter http://localhost:8080/manager, I get a 404 error (reported by tomcat). I saw in the list archive the same trouble, but no solution was found :-( May I be more lucky ?

RE: Lock on database file not being released...
In the ODBC connection entry in the registry, or by using the ODBC Connection editor, change those two parameters. They are probably set for Yes and should be set to No. If you are not using an ODBC Connection entry, then you need to pass these as arguments in the connection string. -Original Message- From: Chaikin, Yaakov Y (US SSA) [mailto:[EMAIL PROTECTED] Sent: Sunday, December 07, 2003 11:07 PM To: Tomcat Users List Subject: RE: Lock on database file not being released... How do I do that in server.xml file? Is that what you are suggesting? Specifying other parameters for the connection pooling? Please elaborate on what you think I should do. Thanks.

RE: Lock on database file not being released...
OK, I now think I know the issue. Try changing the entries for the ODBC connection. Specifically change: ImplicitCommitSync And UserCommitSync The docs are inconsistent on their usage, and I think the drivers vary depending upon the version of the Jet engine you are using. Anyhow, adjust these and see what happens. -Original Message- From: Chaikin, Yaakov Y (US SSA) [mailto:[EMAIL PROTECTED] Sent: Sunday, December 07, 2003 2:13 PM To: Tomcat Users List Subject: RE: Lock on database file not being released... > > However, I have used this driver before in a standalone app and when you > close a connection, it certainly does release the lock on the database file. > > This makes me think, you didn't use pooling in this standalone app. Therefor > check weather you close all your ResultSets and Statements.

Steffen, I tried what you said and closed the ResultSet and Statement before I close the Connection. Still same affect. Any other ideas anyone? I highly doubt it's the driver. I would bet that I am doing something wrong. I just can't figure out what it is.

RE: Lock on database file not being released...
One other question. What is the setting of AutoCommit? Are you setting it to TRUE? -Original Message- From: Chaikin, Yaakov Y (US SSA) [mailto:[EMAIL PROTECTED] Sent: Sunday, December 07, 2003 2:13 PM To: Tomcat Users List Subject: RE: Lock on database file not being released... > > However, I have used this driver before in a standalone app and when you > close a connection, it certainly does release the lock on the database file. > > This makes me think, you didn't use pooling in this standalone app. Therefor > check weather you close all your ResultSets and Statements.

Steffen, I tried what you said and closed the ResultSet and Statement before I close the Connection. Still same affect. Any other ideas anyone? I highly doubt it's the driver.

RE: Lock on database file not being released...
A common problem in beginner JDBC is not performing a ROLLBACK when an update fails. Even when autocommit is set to TRUE, a failed update will leave the records locked in the database. Update statements should always be coded so that if an exception is thrown, a rollback is performed on the connection. -Original Message- From: SH Solutions [mailto:[EMAIL PROTECTED] Sent: Sunday, December 07, 2003 10:51 AM To: 'Tomcat Users List' Subject: AW: Lock on database file not being released... Hi > However, I have used this driver before in a standalone app and when you close a connection, it certainly does release the lock on the database file. This makes me think, you didn't use pooling in this standalone app. Therefor check weather you close all your ResultSets and Statements. In standalone apps where no pooling is involved, they are caught by the garbage collector, but not in connection pooling. Trapped into this myself. cu Steffen - 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]
