Stupid servlet question...

[Mikael Aronsson]

Hi !

I have an application scope servlet and it works fine, but I would like to
run it all the time as soon as tomcat starts, not just after the first use,
is this possible ?

Re: How much memory does Tomcat really use?

[Mikael Aronsson]

A basic out of the box Tomcat 5.0.12 is pretty happy with around 30MB on a
windows machine, but it's always tricky to say how much memory it will use
as it depends on lots of other things, how you configure it and the kind of
applications you run on it, but  40-50MB could be an ok guess on Windows.

Ahh!, sorry to bug you all in that case, I will check later today, I was
assuming that the error was related to the deprecation message, it looked
that way

JDK 1.4 /Tomcat 4 problem...

[Mikael Aronsson]

Hi !

When use Tomcat 4.0.3 I get:
org.apache.jasper.JasperException: Unable to compile class for JSPNote:
sun.tools.javac.Main has been deprecated.

I read that there is a problem with JDK 1.4, but as I understand it this
should only be a warning, I have digged around a bit but I have not found an
anser to this, I have read some posts that people do run Tomcat 4 with JDK
1.4 so I am doing something wrong, but what... ?

Any ideas ?

Re: ## Out of Environment space ##

[Mikael Aronsson]

You need to increase the environment space, command.com has a switch for
this, I don't remember in my head what it is though, type command /? and you
should get info about it. Modify your config.sys so that this option is used
for the default command.com

Hi !

Already done, (I am using Linux 50% of the time so that's the first thing I

Re: web-inf/classes not found ?

[Mikael Aronsson]

Ok, thanks, I will see if I can figure out how to do that

The documentation says that Tomcat (4) always adds a classloader for each
web application that looks in the web-inf/classes and web-inf/dir directory,
I could not find any examples/web-inf/classes reference in my server.xml, I
guess I should place this information in the context for my application but
I have no idea where, but I will see if I can find anything about it in the
documentation.

web-inf/classes not found ?

[Mikael Aronsson]

Hi !

Tomcat complains that it can't find some of my classes
.../web-inf/classes/xxx/yyy/myclassses for example,
Everything works fine when I compile it (I specify the -classpath to let the
compiler find the classes), but when I run the application in Tomcat, it
does not find the classes.

The docs says that it should look in the web-inf/classes directory ?

Am I doing something wrong here maybe ?

Re: java.lang.SecurityException: sealing violation

I am not sure but I belive this is because you are using the JAXP 1.1
libraries from the sun download site, those files does not work with TC4,
you must use the jaxp.jar and crimson.jar files included with TC4 (in the
jasper directory).

was (Security problems....)

[Mikael Aronsson]

Hi again !

It wasn't a security problem after all, an old applet was used instead of
the one I had compiled, I am not sure yet what failed, but it's weird, when
I emptied that classloader cache in the Java console and emptied the
Internet explorer cache it started to work, but I am not sure why the cache
would fail, the clock is running fine and so on so this shouldn't happen,
anyway it is a bit scary that the JVM might run an old applet in the cache
instead of the one I have compiled and placed on the server.

But as I said I am not sure if this is a Java problem of if it's my Internet
Explorer that does this to me

Mikael

Security problem....

[Mikael Aronsson]

Hi !

When I try to run this from an applet:
URL df = getCodeBase();
iconReport = new ImageIcon( new URL( df, "images/i_report.gif"));

I Get:
Java.security.AccessControlException: access denied (java.io.FilePermission
images/i_report.gif read)
 at java.security.AccessControlContext.checkPermission(Unknown Source)
 at java.security.AccessController.checkPermission(Unknown Source)
 at java.lang.SecurityManager.checkPermission(Unknown Source)
 at java.lang.SecurityManager.checkRead(Unknown Source)
 at sun.awt.SunToolkit.getImageFromHash(Unknown Source)
 at sun.awt.SunToolkit.getImage(Unknown Source)

But in another place in the code I have:
df = new URL( getCodeBase(), "stntree.dat");
BufferedReader  in = new BufferedReader( new InputStreamReader(
df.openStream(), "UTF-16"));

And this works fine without any problems, I thought it had something to do
with the images subdirectory, but even if I put the gif files in the same
directory as the applet it does not work.

Is there anything special I have to do to read an icon ?

(Windows2000 and Tomcat 4.0)

They (MS) claim to have fixed this in VB.NET.

They also claim to have fixed this, they have support for multiple .dlls
with different versions, but it only works on XP (I think), and it's a
pretty ugly solution if I understand it all correct (which I might not do of
course, I often have problems figuring out what MS is trying to do ;o)

Tomcat vs. Apache

[Mikael Aronsson]

Hi !

Apache is faster then Tomcat, and in some documents I have also found
information that Tomcat should be less robust then Apache.

I am running Tomcat locally on my computer and so far I have not noticed any
performance problems, I am developing an intranet application that use alot
of JSP and applets, but the number of users is pretty low, say maybe 5-10
active users.

So, is it ok to use Tomcat for a solution like this ?, it would be
interesting to know a little of where the bottlenecks are in Tomcat..., at
the moment I don't have any possibility to try it out in a realistic
environment, so it would be nice to have a clue if I should go for a
solution with Tomcat and a separate HTTP server or use Tomcat alone.
