Re: Tomcat and Threads
You can also try using the TimerTask, as follows: In the context.xml create a bean as follows: The TimerBean can be very simple. I typically have an init(), destroy(), and setters for the parameters (setParam1, setParam2). The Bean needs to create a Timer and can be used to invoke a TimerTask. All this is explained pretty thoroughly in the jdk 1.5. To invoke the bean it can be done either through a servlet or a ServletListener. One of the nice things of doing it this way is that only one task will run at a time and it doesn't require much work to set up. I'd be curious to see what people think of this idea, because even though it works well for me there might be a better way. Richard Toren Christopher K.

Converting characters to "ascii" value
I know "Ascii value" isn't quite the correct term, but it's the only one I could come up with. What Im trying to come up with is the simplest way of coming up with the numeric value associated with a given character, and to go back the other direction as well. In VB, these are the ASC() and chr() functions. I know how to get these values by going through a Byte type, but is there a quicker way to get (for example): Starting with "B", return 66, or starting with " " (one space), return 32? Going the other way, 66 should return "B", and 32 should return " ". Thanks for any suggestions! DAve - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Converting characters to "ascii" value
char is a numeric type. You might try this code as an example: char c = 32; c += '@'; if(c > 31) System.out.println(c + " = " + (int)c); The exception is it adds to strings as a character, thus the cast is needed.

Re: Converting characters to "ascii" value
The first 127 characters of Unicode are in fact ASCII (might be the first 255, I'm not sure, but the first 127 for sure). In other words, it you do: int i = (int)'A'; will result in i=65, the ASCII value for A. char is a numeric type remember, so you don't really have to cast to int, I just did it that way to better illustrate what was happening. To go the other way, it's just: int i = 65; char c = (char)i; That assumes i<127.

Re: Converting characters to "ascii" value
Hum... I am missing something or you just want to cast a char to a byte/int
in Java?
char x = 'B'; // or "Bravo".charAt(0) if you start with a string
byte y = (byte) x;
System.out.println("y=" + y); // should give you 66
and vice-versa:
char z = (char) y;
System.out.println("z=" + z); // should give you B
The only thing you need to watch is the byte number, I think you get a
number between -128 and +127, so you may need to adjuct depending on your
needs.

Re: Converting characters to "ascii" value
To be more specific than my last message, my ultimate goal is to be able
to do something like:
String myString = "ABCDEFG"
Integer myInt = myString.whateverMethod( myString.substring( 1, 2 ))
// should return 66
I can do this by going through a byte[], but was looking for a more
straight forward method, something like VB's asc() function:
In VB:
myInt = asc( mid$( myString, 2,1)) // returns 66
Integer myInt = myString.asc( myString.substring( 1, 2 )) // would
return 66 if the asc() method existed

UserDatabase with something else than a basic MemoryUserDatabase
Hi, I'm trying to configure Tomcat (5.5) with a DataSource realm the "proper" way. Configuring a DataSourceRealm directly is fine http://tomcat.apache.org/tomcat-5.5-doc/manager-howto.html#List%20Available%20Security%20Roles>. But also to conform with the sample server.xml given at install, which configures a MemoryUserDatabase first and then point the realm to this UserDatabse, which seams to make sense in the J2EE kind of approach. Anyway, in order to do this you need some sort of UserDatabase factory. But when you look in the API in org.apache.catalina.users, o deception! the only factory you can find is MemoryUserDatabaseFactory... no DataSourceUserDatabaseFactory or even JDBCUserDatabaseFactory as you would logically expect?... As we know MemoryRealm (and MemoryUserDatabase) is fairly useless in a production environment, so why would they have been to all the trouble of coming up with this UserDatabase thing if no corresponding implementation exists for the other realm types? That's when I say: I must be missing something reeeally obvious here... Any help welcome! Cheers, Nic

or, in 1.5
int b = (int)(myString.substring(1,2).charAt(0)));
?
in java you don't need asc, since each char can be assign to an
integer an vice versa

However, when I try to access "JSP examples" or "servlet examples" in the left panel menu, I get a 404 page (The requested resource is not available). Similarly, when I choose "Tomcat manager" link on the left, the jsp-examples and servlets-examples applications are shown not running and cannot be started. Can someone advise?

The only thing you need to watch is the byte number, I think you get a
number between -128 and +127, so you may need to adjuct depending on
your
needs.
BTW I've not tested the code above, I'm just typing it as I speak.

What Im trying to come up with is the simplest way of coming up

numeric value associated with a given character, and to go back the
other direction as well. In VB, these are the ASC() and chr()
functions. I know how to get these values by going through a Byte
type,
but is there a quicker way to get (for example):
Starting with "B", return 66, or starting with " " (one space),
return 32?
Going the other way, 66 should return "B", and 32 should return " ".
Thanks for any suggestions!

Re: UserDatabase with something else than a basic MemoryUserDatabase
Yeah, well, UserDatabase didn't really attract many followers :). It's a nice concept, with a really s*cky implementation (esp. how it works with /admin :). At one point, there was an attempt at a JDBC UserDatabase, but it fizzled. Short story: You're not missing anything. UserDatabase is currently the unloved orphaned child of Tomcat ;-). "Nic Daniau" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] Hi, I'm trying to configure Tomcat (5.5) with a DataSource realm the "proper" way. Configuring a DataSourceRealm directly is fine http://tomcat.apache.org/tomcat-5.5-doc/manager-howto.html#List%20Available%20Security%20Roles>. But also to conform with the sample server.xml given at install, which configures a MemoryUserDatabase first and then point the realm to this UserDatabse, which seams to make sense in the J2EE kind of approach. Anyway, in order to do this you need some sort of UserDatabase factory. But when you look in the API in org.apache.catalina.users, o deception! the only factory you can find is MemoryUserDatabaseFactory... no DataSourceUserDatabaseFactory or even JDBCUserDatabaseFactory as you would logically expect?... As we know MemoryRealm (and MemoryUserDatabase) is fairly useless in a production environment, so why would they have been to all the trouble of coming up with this UserDatabase thing if no corresponding implementation exists for the other realm types? That's when I say: I must be missing something reeeally obvious here... Any help welcome! Cheers, Nic - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: tomcat examples
Thanks for the answer. As far as the second part is concerned, I found that I needed to stick docBase="C:\bar" workDir="C:\bar\work" /> in the $CATALINA_HOME/conf/server.xml file, and it works. As far as examples are concented, I have installed everything, so the examples with all the files are in place, e.g. in $CATALINA_HOME/webapps/jsp-examples. Tomcat is running as a service, "Local system". I am accessing from the local computer, so that should work. As appears, any valid thing placed in $CATALINA_HOME/webapps works, except these two: jsp-examples and servlets-examples. Any more suggestions? Konstantin.

Re: Somewhat OT: Multiple auth methods in one webapp?
FYI, I did a little research... the 2.4 DTD states the affinity of the element as ?, so you are allowed at most a single auth method. So, while you can of course configure as many constraints as you want, they all must share the same method, one per context. This means that, in answer to my original question, the only way I can do it if I want the Web Services to be in the same context is to write a filter to do basic auth.

On reflection this will be a big fat pain in the arse at the session attribute used by the container is the subject or principal... session.setAttribute(subject,subject).. or something like that. Having 2 realms even if theoretically possible would be a pain because you secondary auth would overwrite the first. If you wanted to restrict access to a service via a second login form, if the user messed up this login it could invalidate his/her existing login which could be behaviour you dont want.

Re: Tomcat and Threads
Hello, I had the same question in my mind some time ago. I have a web application which creates a timer in a context listener init(), which wakes up in 30seconds or so, and destroys the timer in context listener destroy(). It should complete its processing before server stops, so I did some experiments. If I use Timer and TimerTask in J2SE, stopping the application does not wait timer task to complete if its running (it is a behaviour we can guess), however timer task is not killed and it is completed after context listener destroy() finishes. The situation is different if you stop tomcat, where timer and its associated task if its running is killed immediately. In windows, tomcat monitor has a timeout parameter, I think this adjust the time it should wait for all user threads to die. I dont know if there is such a parameter in *nix environments. Since I need to wait for Task to complete, I do it by putting some synchronization controls when destroying timer. This solves the problem if you only stop the application. However, stopping tomcat still kills the thread in windows environment, so I adjust the timeout parameter to a reasonable value (this may be an issue on windows platforms only, I remember stopping tomcat in linux waits for threads if you do some synchronization). Later, I moved to Quartz framework which has a stop function which waits for task to complete. Surprisingly, stopping tomcat also waits for timer tasks (jobs) if I use Quartz (even with zero timeout on windows). So, it is clear I miss a big point when I use my own Timer/TimerTask and thread controls. I did those experiments some time ago, some points may be wrong or out of date. You can easily try it by yourself.
