RE: Urgent : Problems with JDBC Date formats...
In that case perhaps you could try using the SQL TO_DATE function. I'm
not sure what the proper syntax for this is, but in Oracle you could use
something like:
Select * From table WHERE (dateField = TO_DATE('2001/01/01',
'/mm/dd'))
failing that, see if you can change the default date format in the
database.

I tried to understand the Dr Watson log file also...And if I am not wrong, I could understand that the log file is showing faults in the system functions like, MPHeapFree or RtlEnterCriticalSection or something like that.. (If you want then i can send you the chunk of that log file also...). I could identify the sequence of actions also, where the majority times the Tomcat crashes... One sequence is ...In IE/NS browser, i log into my application, then with Ctrl+N, i open another window and then from both of the browser windows, i surf thru different modules and pages, till then it works fine...no probs... then, i log out from one of the browser window (which obviously logs me out in another browser also...) and close one of the window. Then I again log into the application from the open window...and go thru different pages and do some heavy database access stuff...like searching, updating tables and all... and during this at some point in time...the tomcat crashes...(dr watson error). Now, as I have gone thru the Archieves of the Tomcat Users mailing list...i've frequently seen people saying that JDBC ODBC driver is not THREAD SAFE and it should NOT be used for production and Sun is also saying that JDBC ODBC driver is just experimental and having some problems which they are not going to solve...(sun bug parade...).. and people advice to use some other database access drivers.so, can somebody advice me that exactly which driver should I use...and where it is available...(which should be freely available, should allow my code to work with that also without changes, and easily implementable...) ...as within next two days I've to launch the application. eagerly waiting for solutions, TIA, thanks and regards, Chintan Shah

The arguments to the remote metho dmust be serializable at runtime. The HttpRequest of Catalina's isn't so you wont be able to do that.

Re: MyClass.getPackage() == null... Why?
Hi,
I'm not sure if this is going to help, but... from the jdk javadoc:
the package of the class, or null if no package information is available
from the archive or codebase.
It doesn't really clarify when no package information would be
available... but in the Package docs:
Package objects contain version information about the implementation and
specification of a Java package. This versioning information is retrieved
and made available by the classloader that loaded the
class(es). Typically, it is stored in the manifest that is distributed
with the classes.
I guess your a jar has no manifest .. so because there's no manifest,
there's no package information. From what I can see (and I haven't
looked far, so dont rely on this too much) the getPackage doesn't map to a
package as in com.MyClass belonging to the com package...
anyway, I hope that helps a little... I think you might be able to find
more in the javadocs, there looks like there's a fair bit around Package
and Class that might be helpful.

But if I import explicitly java.io.IOException, it might cause unqualified

I dont think there is a tomcat IOException... the compiler was looking for
that class because it was compiling a servlet that referenced a class
IOException - which wasn't imported
I agree that it's good practice to import each class individually using
fully-qualified names. However (IMHO), the Tomcat development team ought to
have imported any internal implementation classes explicitly where there's
a risk of namespace collision with very common classes.
big diff between jsp and code though... 110% in code you should never
(unless you absolutely have to - org.w3c.dom.Document and
org.jdom.Document a good example where you do have to) have package names
in code, they should always be explicit imports... IMHO (o:
It would have been better still if the fully-qualified names class names
were used directly in the code for Tomcat, with no imports whatsoever --
because if both the internal Tomcat classes and other classes with the same
names are ALL imported explicitly, there's still as much potential for
confusion.
the servlet code generated by jasper only imports the servlet and jsp
packages and the jasper packages perhaps even the jasper packages
shouldn't be imported, but hey...
I assume though that this fixed it?

Using fully-qualified class names everywhere in application code slows down
development (more typing) and may reduce readability (ok, you know which
class is which, but lines of code won't fit easily on screen at the same
time!).

This is the same thing that causes an issue with struts: using struts, and jboss with embedded tomcat. if the struts.jar is in the jboss/lib/ext (command classpath) then it cannot find form or action classes that are in the web application.

Re: accessing servlets without a port number
Alex, port 80 is the default port for http, so what you are wanting to do is have tomcat listen on port 80 instead of 8080. to do this on a *nix box you'd need to run tomcat as root (for 3.x anyway - I believe 4.0 has a wrapper that does this properly), which isn't a good idea. alternatively, if you are using apache as well, then you need to configure mod_jk. a good place to start is the docs in the distribution - have a look at mod_jk, or edit server.xml and change 8080 to 80. cheesr dim On Fri, 31 Aug 2001, alex reuter wrote: Hello List, I'd like to access my servlets without using the port number, and I've seen a whole bunch of config files and directives and I was wondering if anyone could tell me exactly how its done, or point me to some solid documentation.

Re: Custom Tag Can't Compile problem.
This is not based on any knowledge of jasper, but do you get the exception
if you declare TagManager in a package? My guess is that jasper uses the
fully qualified form of the tag name in declaring the tag in the jsp and
the fact that you dont use a package is upsetting it.
having said that - its a guess...

RE: how to make a servlet as the home page
Ok, if you're using apache, then the first thing apache does when it gets a request for a directory is look for the DirectoryIndex instruction. typically this will be set to index.html index.htm index.jsp etc. The way this works is that apache will first check index.html, then index.htm, then index.jsp and serve whichever comes first. the second part of the equation is the JkMount directives. Say you create a directive JkMount /MyHomePageServlet ajp13 then you can set DirectoryIndex MyHomePageServlet index.html index.htm index.jsp and afaik apache should route the request for / to tomcat, and tomcat will know how to serve /MyHomePageServlet. just a warning this is all theory, I haven't tested it, but I think the concepts are right. hth, cheesr dim - Original Message - From: naveen [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Sunday, August 26, 2001 9:29 PM Subject: how to make a servlet as the home page hi , I am using tomcat and apache, I want to make a servlet as the home page of my web site, when i access http://www.mysite.com/, a servlet needs to be called and the most important thing in this is I need to access HTTP variables like Remote Host, etc. thanks in advance

Re: Imaginative webapp setup. Is this possible to do?
yep - but it'd be something you'd do in one webapp... put some logic in your servlet (assuming you're using model-2 arch) that looks at the request, and uses the appropriate jsp... have some protocol like hostname + _homepage.jsp... for static html, probably be easier to use apache virtuals for that... cheesr dim On Wed, 22 Aug 2001, Gabriel J Zimmerman wrote: I have a server that has many virtual hosts, say http://www.myhost1.com/, http://www.myhost2.com, http://www.myhost3.com etc. etc. Is it possible to create a webapp that is hosted at the / level for each of these hosts, where the servlets,tag libraries, and java classes located in the WEB-INF section would all be the same but where the docs and JSP files would be unique for each host? By unique, I mean that each host would have its own html files, JSP files, image files etc., which would not be accessable from the other hosts. Thanks, Gabe Zimmerman

Such classes are shared across web apps, so this should accomplish your goal of having a single cache. They are loaded from a (common) parent class loader to the one for each web app. Wont this still result in one init() call per servlet per context? The only think you'll gain is the use of static variables right? Obviously these could be used to achieve the desired outcome, but you wouldn't get one context with two paths...? I'm not using the latest servlet spec (2.3). Anyway, the simplest solutuion will be to put all my classes on the system classpath, this should work. I have no jsp's and don't need dynamic class reloading in production, so I beleive it's perfectly legal in my case. you would be well advised to put it in a jar which you then place in tomcat's lib dir... that way its relatively easy to move your app. cheers dim
Re: web.xml problems
Sounds like a case issue...

Eerything in Tomcat's lib directory is shared -- everything in /WEB-INF/classes or /WEB-INF/lib is not shared. My reading of the suggestion was that the classes would reside elsewhere in the system but be in the startup classpath as startup - this would do the same thing but be a little more spread out... thats all my point was there (o: cheesr dim
Re: a simple ( irritating) classpath problem
hi, There are three basic areas that classes can be put in tomcat: WEB-INF/classes - contains all the classes that form the web application WEB-INF/lib - contains jars that the web application uses TOMCAT_HOME/lib - contains jars that are available to _all_ applications using tomcat because i put all the package (com.oreilly.servlet.*) in the same directory with the servlet (under web-inf/classes/ com/servlet/ directory) if it is the package com.oreilly.servlet then it should go in WEB-INF/classes/com/oreilly/servlet - even better, I assume you got it as a jar, just put the jar in WEB-INF/lib . If it is a zip, then rename it to a jar. i tried putting the cos.jar file in the web-inf/lib directory, it didn't work what do you mean it didn't work? try jar -tf cos.jar to check that the classes are in the jar. I assume you are importing the required classes and that they exist in the jar. in put these files directly under the web-inf/classes/ directory , it didn't work either again, should be according to package then i added the full path tomcat_home/lib/cos.jar, to the classpath, didn't work either. I'm not sure why that didn't work - although if you put cos.jar in the classpath it _should_ be available to all web applications. well, i gave up, i just wanted to learn the LOGICAL way to set the classpath up. you dont need to set the classpath yourself. just put your jars in WEB-INF/lib and your classes in WEB-INF/classes hth, cheers dim
