RE: Interfaces and cast problems in Tomcat
What does the following tell you?
interfaz_dbms.cacheable temp;
temp = interfaz_dbms.cache.getReferencia().Buscar(id,n.getTipo());
// add this code below...
if (temp!=null) {
System.out.println("class >" + temp.getClass() + "<");
}
// back to your code...
n= (materia.materias)temp;
Whatever is output between the >< symbols should be what you're trying to
cast to. That code above is not meant to be used to program better (don't
try to use that code for 'real'), only to help others on the list diagnose
what the class is/should be.
For example, if we see the output:
Class >Materia.materias< that means you haven't spelt the package named
correctly in your cast (Java is case-sensitive).

RE: Tomcat's scalability
My feeling is that by calling an installatin of 'java' or 'the jdk/jre' a 'jvm' is going to produce confusion. /usr/local/applications/tomcat1 /usr/local/applications/tomcat2 /usr/local/applications/tomcat3 /usr/local/java That's one *JDK/JRE*, and 3 tomcat *instances*. Each tomcat startup file uses the same JDK to launch a separate *JVM* (so 3 JVMs equates directly to 3 tomcat instances) because as Leon says, you can't run 2 tomcats in a single JVM. So no need to install java more than once, just launch multiple JVMs (and thus, multiple tomcats). We do this on a single CPU box, because we find we 'need' to manage the memory of the webapps running in each instance. So if we 'need' to bounce a tomcat server because it's got 1% free and isn't getting any better, then we still have the other two tomcats serving the websites they serve. And I always say 'need' in quotes because yes, one day we'll track down our leaks and then we won't 'need' to do that. Of course, we're still CPU-bound, so there's no real 'performance' or 'scalability' enhancement by having more than one instance on a single box. We'd get that (I think) if we clustered more than one physical box each with its own tomcat/jvm instance, or by clustering multiple tomcats on a a single, multiple-cpu box. That last paragraph is my own weak understanding of CPUs/scalability/clustering, so could be off. > -Original Message- > From: Biernatowski Bartosz J [mailto:[EMAIL PROTECTED] > Sent: Monday, June 19, 2006 4:55 PM > To: 'Tomcat Users List' > Subject: RE: Tomcat's scalability > > > My understanding of Tomcat's instance is having both > Tomcat+JVM installed in separate directories.

RE: How does Tomcat detect whether a browser accepts cookies
Just because it's fun to have that one last kick at the dead horse...
You really can't rely on any cookie being set, can you? I mean most users
are simply not this savvy (or stupid, depending on how you feel about it),
but I can set my browser to prompt for every cookie, and I as the (idiot?)
user can reject the session cookie, and then accept every other cookie. Or,
I can accept the session cookie (because it's a *session* cookie, the kind
that disappear), and reject all others. In fact, doesn't one of them there
browsers have a setting like that, to automatically accept session cookies,
but prompt for the other ones?
So no, I don't think you can reliably use isRequestedSessionIdFromCookie to
tell whether or not a client "accepts cookies". Not all cookies are alike.

Re: Yet another try: mod_jk 1.2.18 release candidate ready to test
Any reason the section titling on that page is so confusing? "Changes from the released JK 1.2.18" makes me think I'm looking at the changes that have been made *since* 1.2.18 and will be included in some, as yet un-numbered, future release. If that's actually correct... you mean I have to make the mental calcuation "I want to know what changed in version x, therefore look for a title that says version x-1" every time I look at a changelog? I'd suggest a tile like "JK 1.2.18 Changes" or even just "JK 1.2.18" (as it is for TC).

So even if you *could* cast it back out to the right type (which in my own testing, I haven't managed to do)... you now have a situation where any class can now access your private inner class of another class? (Because any other JSP page can call session.getAttribute). If that's the usage you want, then why bother making it a "private inner class" in the first place? Also, the classname for inner classes has the $ in it, and for JSP pages, has the name of the jsp page prepended as well. In my own test, I put a page at the root of the webapp named test.jsp and the classname of the inner class was: instanceObj.getClass() = class org.apache.jsp.test_jsp$MyInnerClass none of these work: (org.apache.jsp.test_jsp$MyInnerClass)foo (test_jsp$MyInnerClass)foo (test_jsp.MyInnerClass)foo In fact, the nice little "perchance you meant" in the stack trace tells me someone has a sense of humour about these sorts of situations. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: reading file in ServletContextListener
the javadoc for org.xml.sax.InputSource indicates it can take an
InputStream.
parser.parse(
new InputSource(
context.getResourceAsStream("/WEB-INF/classes/friends.xml")
)
);
You might also get away with the following:
parser.parse(
context.getRealPath("/WEB-INF/friends.xml");
);
Note: the first uses getResourceAsStream, so the file must be found in a
classloader (thus, your file is under /WEB-INF/classes). The second is just
a real path to the file, so it can be anywhere. The second is closest to
what you were trying initially. I'm not familiar with that API, so perhaps a
String that indicates "the location of the file" would work, but where "/"
is (without the getRealPath part) is "the directory from which Tomcat is
being started", and who knows (or should have to care) where that is.
In both examples above, 'context' would be obtained:
ServletContext context = servletContextEvent.getServletContext();

RE: reading file in ServletContextListener
whoops. I meant to say "/" is the root of the filesystem and _not_ having a slash would mean "the current directory", so that would be "where tomcat has been started from".

RE: File Download not working for anchor tags
Display and generation are two separate issues and I'm confused about which is which for the OP. does the anchor tag link to an actual real file on the filesystem somewhere, like: click to download or are you linking to a dynamically generated file, as from a servlet: click to download in the first case, you're using JSP to display the link and it's more likely a web-server MIME type that is missing. Are you using TC stand-alone or fronted with Apache? in the second case, you need to worry about setting headers in your servlet/JSP (the generating servlet/jsp, _not_ the display one) both for content type and that disposition setting which is the FAQ that Tim linked to, because now you're generating the contents of the linked "file" in a JSP or servlet (so actually, not a file, but rather a streamed response). > -Original Message- > From: Mike [mailto:[EMAIL PROTECTED] > Sent: Wednesday, November 30, 2005 5:36 PM > To: Tomcat Users List > Subject: Re: File Download not working for anchor tags > > > > I'm using a JSP page for displaying the anchor actually. > The anchor is > linked to a file, either a .xls or .csv file. > >Mike > > At 04:09 PM 11/30/2005, you wrote: > >I assume you are using a servlet since JSPs always return a > >Content-Type. > >Try setting Content-Type in your servlet so the headers are > identical. > > > >Mark > > > >Mike wrote: > >>Hi Mark, > >> I compared them and the Content-Type is not showing in > 4.1.31.

Yah, I don't think that's right either, and besides that, it's a little backwards to describe it as you have. A sessions doesn't so much access servlets, as the servlets (more than one, regardless of their single-threadness) can access a single Session at once. Sessions are (never?) thread-safe. Which is perhaps one reason why SingleThreadModel was deprecated. People thought by using that interface that they would never have to worry about synch issues again. Even if you have nothing but singleThread servlets, that only prevents concurrent access to that servlet. Neither singleThread servlets nor any other mechanism I'm aware of can prevents concurrent access to a single Session object.

RE: PreparedStatement w/ Connection Pooling
I've looked at the CVS HEAD for PoolingConnection...
http://cvs.apache.org/viewcvs.cgi/jakarta-commons/dbcp/src/java/org/apache/c
ommons/dbcp/PoolingConnection.java?view=markup
public synchronized PreparedStatement prepareStatement(String sql) throws
SQLException {
try {
return(PreparedStatement)(_pstmtPool.borrowObject(createKey(sql)));
>From this code, I surmise the following:
When you do multiple calls to prepareStatement(foo), where 'foo' contains
the same SQL string, then the "PoolingConnection" object will automatically
give you back a previously pooled preparedstatement. So the answer to you
question: "how do I access these pooled statement?" might be as simple as
"don't worry about it, just use the prepareStatement() API and DBCP handles
it for you".
I don't know for sure and you'll probably get more traction asking this
specific question on the commons-user email list. And uh.. I probably coulda

RE: Connection Pool Woes
That it's registered with JNDI does not help. But perhaps what is really meant is "configure your pool through Tomcat's built-in support for DBCP (which uses JNDI)". Then you'd get whatever management of the pool that Tomcat brings (for example, when the webapp is shutdown, it will .close() the pool itself, which perhaps you'd forget to do, if you manage your own pooling). But other than that, I can't think of what advantage it would bring. > -Original Message- > From: Alex Turner [mailto:[EMAIL PROTECTED] > Sent: Monday, January 23, 2006 11:54 AM > To: Tomcat Users List > Subject: Re: Connection Pool Woes > > > How does registering my pooling datasource with a naming > directory help connection management?

RE: Logging session timeouts
Well let's just think about that for a second. Filter: a filter is called each and every time you make a web request. So even if the filter is highly efficient, if you make 1000 requests in a session, you (that is, the container) will invoke the filter's doFilter method 1000 times.

you're missing this:
if (rst.next()) {

}
you're also missing a WHERE clause in the query. You'll select everything
from testdata, by rs.next() will only get you to the first row. To process
all rows, you make it a "while (rst.next()) { ", but then it would have to
be some sort of concatenation operation instead of just
blob=rst.getInt("chest"), because of course, if you did 'while', blob would
only contain the *last* row. So if you're interested in just the first row
or just the last row, there are more efficient ways of obtaining them.

Trouble finding Datsource Resource with DataSourceRealm
My Tomcat's having trouble finding the JNDI Datasource to use for a
DataSourceRealm.
Details:
Tomcat 5.0.28
Java 1.4.2_04-b05
on Linux
partial server.xml:
factory
org.apache.commons.dbcp.BasicDataSourceFactory
username
username
password
secret
driverClassName
com.mysql.jdbc.Driver
url
jdbc:mysql://xxx.xxx.xxx.xxx:/?autoReconnect=true
snip DBCP params
mail.smtp.host
.globallyboundless.com
web.xml is (I think) not useful in diagnosis.
I remove all files from the logs directory, and restart the server. The
entire contents of catalina.out, (hopefully) formatted for readability. So
the only thing different between this and the actual output is whitespace
and newlines.

So you can see from the output everything seems good, though the Realm not
showing up is strange. But it is being configured, because when I browse to
http://foo.globallyboundless.com, it tries to authenticate (the browser
throws up the BASIC dialog box), but it fails with this in the engine log:

RE: Trouble finding Datsource Resource with DataSourceRealm
I should have mentioned, I have a ContextListener that contains the
following:
---
initCtx = new InitialContext();
envCtx = (Context) initCtx.lookup("java:comp/env");
logger.info("*** loading Data Source");
try {
ds = (DataSource) envCtx.lookup("sql/DataSource");
application.setAttribute("services.datasource", ds);
logger.info("*** DataSource loaded @ services.datasource");
} catch (NamingException ne) {
logger.fatal("ERROR loading DataSource: ", ne);
}
---
And I get both 'info' messages. So the DataSource resource is being loaded,
and it *can* be found at "sql/DataSource" (by my code in the context
listener). It's just the Realm that can't seem to find it, as indicated by
the stacktrace below.
However, leaving no stone un-turned, I deleted the entire work directory for
the 'foo' host and get the same result.
This still appears in the engine log when I attempt to authenticate:

RE: Trouble finding Datsource Resource with DataSourceRealm
well, I couldn't get a Realm to function when the DataSource it needed was
defined in the same Context as the Realm itself.
I've made it work by declaring the datasource resource in the 'global naming
resources' section of server.xml, and the realm directly under the 'engine'
element. And then in my host, I use a resourcelink to reference (and rename)
the globalresource to what my application is expecting.
still puzzled why I couldn't get the other setup to work.
