RE: Malformed URL Exception: unknown protocol: c
Then I'm at loss as to what the issue is. The fact that it works in some cases, and not others, has me puzzled. I'd suggest digging into the javax.xml source and see if you can figure out the condition that throws the exception, etc. And I'm still not fully clear on whether our C:\... strings are considered valid URI's according to the spec, though they must be, as everything seems to work.

Automatic WAR updates - suggestions wanted
Our Tomcat 5.0.19/Windows 2000 web application is self-updating. It can download the newest version of itself (ie. a .WAR), and then spawn a Windows .bat file to do an app update. This batch file shuts down Tomcat, deletes the webapp's files and directories under Tomcat, copies the new .WAR across, and then restarts Tomcat. Tomcat then redeploys the new WAR. However, very infrequently, one or more files seem to be locked in one of our webapp subdirectories when we try to remove the current app. (We're not yet sure why.) Since not all of the the subdirectories are gone, Tomcat does not redeploy the new .WAR on restart, and our app is effectively dead in the water. Am I missing a setting in server.xml/context.xml/web.xml that can indicate always re-deploy a .WAR, regardless of whether the webapp subdiretory tree is present or not? Thanks.

Hello,
I am trying to use the DBCP features of Tomcat 5.5.7. I created a webapp named
testDB and put it under $CATALINA_HOME/webapps/testDB. Then I created a
testDB.xml file under $CATALINA_HOME/conf/Catalina/localhost/testDB.xml.
// here it is
Context path=/testDB docBase=testDB
debug=5 reloadable=true crossContext=true
Resource name=jdbc/testDB auth=Container type=javax.sql.DataSource

/Context
I have been following the notes from:
http://localhost/tomcat-docs/jndi-datasource-examples-howto.html
I made sure I completed the rest of the tasks.
WEB-INF has the two tag locations, and the resource ref.
eg:
taglib
taglib-uri/WEB-INF/sql.tld/taglib-uri
taglib-location/WEB-INF/sql.tld/taglib-location
/taglib
taglib
taglib-uri/WEB-INF/c.tld/taglib-uri

/taglib
resource-ref
descriptionDB Connection/description
res-ref-namejdbc/testDB/res-ref-name
res-typejavax.sql.DataSource/res-type
res-authContainer/res-auth
/resource-ref
I finally hit my jsp page which is this:
%@ taglib uri=http://java.sun.com/jsp/jstl/sql; prefix=sql %
%@ taglib uri=http://java.sun.com/jsp/jstl/core; prefix=c %

c:forEach var=row items=${rs.rows}
Foo ${row.foo}br/
Bar ${row.bar}br/
/c:forEach
/body
/html
And I get no results:
Now I am pretty sure I have all configured. Because if I use a fallback (Tomcat
4.1) code piece I had, I get results using the same settings:
package foo;
import javax.naming.*;
import javax.sql.*;
import java.sql.*;
public class DBTest {
String foo = Not Connected;
int bar = -1;
public void init() {
try{
Context ctx = new InitialContext();
if(ctx == null )
throw new Exception(Boom - No Context);
DataSource ds =
(DataSource)ctx.lookup(
java:comp/env/jdbc/testDB);
if (ds != null) {
Connection conn = ds.getConnection();
if(conn != null) {
foo = Got Connection +conn.toString();
Statement stmt = conn.createStatement();
ResultSet rst =
stmt.executeQuery(
select id, foo, bar from testdata);
while(rst.next()) {
System.out.println(next );
foo=rst.getString(2);
bar=rst.getInt(3);
}
conn.close();
}
}
}catch(Exception e) {
e.printStackTrace();
}
}
public String getFoo() { return foo; }
public int getBar() { return bar;}
}
And using the above class works all day.
The only difference I see is that the class using a naming import and the jsp
does not. Can anyone help.
Thanks,

e.printStackTrace();

public String getFoo() { return foo; }
public int getBar() { return bar;}

And using the above class works all day.
The only difference I see is that the class using a naming import and the

does not. Can anyone help.

error-page vs. errorPage
Can someone explain the relationship between the error-page element in my webapp's WEB.XML versus the errorPage attribute of the page directive within a JSP? I'm trying to create a single error page that handles any exceptions generated by the JSPs within my webapp, without having to name the error page in every JSP. To start with, I added the following to my web app's WEB.XML to indicate a catch all error page for the app: error-page exception-typejava.lang.Exception/exception-type location/error.jsp/location /error-page I also marked ERROR.JSP as an error page by including the following at the top (note the isErrorPage attribute): %@ page contentType=text/html; charset=ISO-8859-1 buffer=64kb isErrorPage=true % Unfortunately, when trying to access the exception object in ERROR.JSP, I get a NullPointerException, as though it doesn't exist. Since I thought this should work, I must be missing something? (I'm using Tomcat 4.0.4, by the way.) Thanks.

I am having the strangest problem with Tomcat and inner

It seems that somewhere between getting the data from the
result set and
constructing and storing an instance of the (data holding)
inner class in
a
Vector, the data is getting corrupted (doubles only).
Example:
JSP -
%!
// inner class
class SomeClass
{
public double dSomeDouble;
public SomeClass(double dSomeDouble)
{
// label: point 2
this.dSomeDouble = dSomeDouble;

double dDoubleVal = oResult.getDobule(1);
// label: point 1 (dDobuleVal is intact)
oVecResults.add(new SomeClass(dDoubleVal));
// label: point 3
%
END JSP
At point 1 the values retrieved from the database are
intact, and remain
so until passed into the constructor of the inner class.
At point 2
dSomeDouble becomes corrupt (some random number out of memory), and
remains
so past point 3.
Added twist: This problem only occurs after a page has
been hit 5 times
(3
times for larger pages). (1st time, Tomcat compiles the
page, next four
times the page is loaded in memory).
Config: Apache Tomcat 4.0.1 (exact same problem found in Linux and

versions).
Any ideas? Extracting the inner class from the page fixes
the problem,
but
is not a desired solution. Any help is appreciated.

RE: Why ignore sendRedirect() for an include? - solved
This question ended up getting answered back on the JSP list (many thanks
to Hans Bergsten!). The spec very clearly calls out the issue in section
JSP.4.4:
An included page only has access to the JspWriter object and it cannot set
headers. This precludes invoking methods like setCookie(). Attempts to
invoke these methods will be ignored.
My oversight. Thanks anyway.

Subject: Why ignore sendRedirect() for an include?
I started this discussion on the JSP list, but am led to
believe now that
this is a Tomcat issue. Can someone explain otherwise?
My problem is that a sendRedirect() issued by my servlet is not being
honored by Tomcat 4.0.3. The servlet is being called via a
jsp:include
block from within a JSP. The sendRedirect() is the first thing in my
doGet(). As long as the response hasn't been committed,
this should be
legal, right? (I confirmed that the response had not been
committed with
res.isCommitted() .)
To confuse me even more, I found the following in the Tomcat source
(ApplicationHttpResponse.java):
/**
* Disallow codesendRedirect()/code calls on an
included response.
*
* @param location The new location
*
* @exception IOException if an input/output error occurs
*/
public void sendRedirect(String location) throws IOException {
if (!included)
((HttpServletResponse)
getResponse()).sendRedirect(location);
}
Can someone confirm that the reason my sendRedirect() is
failing is because
of the above (!included) check, and even more importantly,
WHY you don't
allow sendRedirect()'s on an included response?
Thanks.

RE: There is no disk in the drive!
See below for article Q102418 from the Microsoft Knowledge Base (http://search.support.microsoft.com/kb/). Maybe you've got a drive in your PATH that XCOPY is having trouble with? One guess is that it's using the System Account when running from Tomcat as a service, but your account when running from the Command Prompt. This might explain the difference in behavior that you're seeing. Either fix the PATH and/or take a look at the Log On As option of the Startup dialog for the service. You might be able to start the service as a different user and fix the problem as well. Jay CAUSE This problem occurs when the PATH statement in the AUTOEXEC.BAT file, Windows NT System Environment Variables, or User Environment Variables for user name references a floppy disk drive or CD-ROM drive. If you reference a floppy disk or CD-ROM drive in the AUTOEXEC.BAT, Windows NT 4.0 does not display the error when you log on but will display the error when you run applications such as EDIT.COM, WRITE.EXE or NOTEPAD.EXE. RESOLUTION To work around this problem, either have a disk in the drive or remove the entry from the PATH statement. The drive letter may not be entered in the PATH statement, but will be found in the following registry location: HKEY_LOCAL_MACHINE\SYSTEM\SETUP\WinntPath Delete it here and log back in. MORE INFORMATION When a user logs into his or her account, Windows NT searches for an AUTOEXEC.BAT file in the root directory of drive C. If the file is found, NTVDM.EXE appends its PATH environment variable to the system PATH environment variable. Only the VDM PATH variable is affected. NTVDM tests the PATH statement for validity. If the drive physically exits, NTVDM tests or the drive type (removable media or fixed). If the drive is a floppy disk or CD-ROM, it tests for the presence of valid media. If none is found, the error message is displayed. If invalid drives are used in the AUTOEXEC.BAT PATH statement, no error message is displayed, but the PATH variable in any VDMs that are opened will be invalid. The same message may also be displayed if you try to start an application such as NOTEPAD.EXE in Program Manager by choosing Run from the File menu. -Original Message- From: Adam Fowler [mailto:[EMAIL PROTECTED]] Sent: Wednesday, July 11, 2001 12:48 PM To: [EMAIL PROTECTED] Subject: Re: There is no disk in the drive!

RE: Servlet -- File -- Web-browser
I agree with your (2) statement below, at least if Apache is running on
Windows. Flushing doesn't really help, as there is a specific issue with
buffering in Apache on Windows. We had to introduce a patch to
HTTP_PROTOCOL.C that someone posted in a newsgroup to solve the
problem. It's comment pretty much summarizes the details:
/*
* WIN32 pipes will ALWAYS block until data arrives,
* therefore the ap_bread() will NEVER return 0,
* therefore we will never flush r-connection-client,
* therefore the client will only get data when we have
* pushed in enough to write to the socket (IOBUFSIZE
* probably) or the script finishes,
* therefore server push does not work.
* Work around this by always flushing before a read.
* This is probably quite inefficient in some cases.
*/
if (ap_bflush(r-connection-client) 0) {
ap_log_rerror(APLOG_MARK, APLOG_INFO, r,
client stopped connection before send body completed);
ap_bsetflag(r-connection-client, B_EOUT, 1);
r-connection-aborted = 1;
break;
}
If you can't find the details of this patch, let me know and I'll send you
a copy of the file. Unfortunately, though, it means you'll have to set up
a build environment for Windows (which is something we didn't have to do
before).

Subject: RE: Servlet -- File -- Web-browser
I didn't answer, because I'd hoped someone could say for sure. But my own
guesses are:
1) The Cancel button in IE doesn't actually do anything once the data
starts streaming. I've suspected this was the case, and it sounds like
you've got evidence.
2) Apache is buffering the response somehow: directly connected to Netscape,
you get an immediate exception when writing to a closed stream; but, with
Apache in the middle, the writes don't happen immediately, and no exception
is propagated to the servlet.
My only advice would be to flush your servlet output early and often: you
might (or might not) get an exception immediately.
