Tomcat User Permession
I'm using mandrake 10.1 as a server, and jakarta-tomcat-5.0.27. My intranet running on tomcat should be updated and should use the mandrake linux users permission for the folders while browsing.

Re: Tomcat User Permession
Question is not clear, but i'll try to reply. All action attempted by any code inside the jvm running tomcat (that is operations done by JSP, servlet, realms, tomcat itself and any other java classes you may add to webapp) are done on behalf of the user which started tomcat. So if you start tomcat by hand like this: [EMAIL PROTECTED]:~/tomcat/jakarta-tomcat-5.5.7$ bin/startup.sh All action will be done on behalf of user 'delbd' If you start tomcat in a startup script, change recommend you set the user to a user named, for example, 'tomcat' which has write access limited to the tomcat directory. Keep in mind, if you want your tomcat to listen on port 80 (this port is reserved for root in linux as it is a so called low port), you will then need to run tomcat as root, which is clearly NOT recommanded! (prefer to run an apache http server on port 80 and prowy the tomcat server using mod_jk) Last but not least, If your tomcat webapp is to serve only html files, it more performant to stick with apache http server!

new Date() returns 0 w/ Tomcat 5.028 on IBM JDK 1.4.2 Linux PPC
Hi, i am getting strange things on the following environment: Tomcat 5.0.28 IBMJDK 1.4.2 on SLES Linux PPC When i start up our webapplication, everything is fine, i am getting current dates back when issuesing new Date() and log4j is also logging like expected. After some minutes new Date() returns timestamp 0 (01/01/1970) and log4j also fails to log dates of course. At the same time, when calling a simple test public static main program which prints new Date() to console, the date is perfect, but in each and every servlet, the same call returns 0. This is really scary, because as we all know, this cant be a problem in the user code. Normally i would say that this is a JVM issue, but like explained, command line java programs work, only serverside program fail here. I will also try to address this one at some IBM related spot. But perhaps some has a clue.

RE: How to create a website in apache-tomcat-5.5.12
Two things: 1. you need to deploy your webapp as the ROOT webapp on the server. there is a standard ROOT webapp that ships with TC, you can just replace that if you want to, examine that to see how to configure it, look especially at the %catalina_home%/webapps/ROOT/WEB-INF/web.xml config file. 2. you need to edit %catalina_home%/conf/server.xml so that TC listens on port 80 rather than 8080, to do that you need to edit this line (from the standard file on TC 5.5.9): Connector port=8080 .. / your webapp is then at the URI of / rather than /myDomain so it's URL will be whatever the server name is, e,g, www.myservername.com .

RE: ? xmlValidation Attribute -- What's it Mean ?
I believe (although am not 100% sure because I haven't tried it myself) that xmlValidation=true means that TC's XML parser should check all XML against the DTD defined in each XML source. With xmlValidation=false, it will check that the xml is well-formed but not that it is valid. See these refs: http://www.w3.org/TR/REC-xml/#dt-valid http://www.w3.org/TR/REC-xml/#dt-wellformed So I think (?) that if you set xmlValidation=true, you must include a DTD link in each XML source. If you do not have one, this might be why you are getting a stacktrace. The reason for the long stacktrace is that the parsing is done by a generic parser bundled into TC, so the TC authors cannot control the call stack, or when exceptions are thrown or the exception messages - they simply wrap them with a higher level exception as appropriate. If it helps, I have reported a similar issue where I thought that TC's wrapping exception message could be made clearer to users. Not sure about Xerces 2.2 but ISTR that there is some issue with a change to the XML parser that ships with TC, this issue is mentioned in 5.5.x release notes so that might be worth a look up http://tomcat.apache.org/tomcat-5.5-doc/RELEASE-NOTES.txt .

Please look at this snippet from the server.xml that is distributed with TC: !-- Define the default virtual host Note: XML Schema validation will not work with Xerces 2.2. -- Host name=localhost appBase=webapps unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false Can anyone tell me what the 'xmlValidation' attribute on Host is for? Obviously it has something to do with XML validation but what XML? Is it the corresponding web.xml? And how does the 'xmlNamespaceAware' attribute fit in? Every web.xml I've ever seen uses the default namespace? And what's the comment about the Xerces 2.2 parser? I'm using Sun's JDK 1.5.0. Does that use Xerces internally? When I set the 'xmlValidation' attribute to 'true' I get a big stack trace. One would think it might be appropriate to offer a nice error message describing the problem. I've looked at the latest TC documentation for Host and it makes no mention of the 'xmlValidation' attribute: http://tomcat.apache.org/tomcat-5.5-doc/config/host.html Can someone please explain these two attributes? My web.xml is getting unwieldy and I'd like to start validating it.

RE: Tomcat is dying unpredictably
A long shot, but if you are running RHL9 you might try this, as mentioned in the TC 5.5 release notes at http://tomcat.apache.org/tomcat-5.5-doc/RELEASE-NOTES.txt : Tomcat on Linux: GLIBC 2.2 / Linux 2.4 users should define an environment variable: export LD_ASSUME_KERNEL=2.2.5 Redhat Linux 9.0 users should use the following setting to avoid stability problems: export LD_ASSUME_KERNEL=2.4.1 Apparently the problem is that RHL introduced the Native Posix thread library, see here (find NPTL in the page to jump to the explanation): http://www.redhat.com/docs/manuals/linux/RHL-9-Manual/release-notes/x86/ I've noticed it handing a JVM that does a lot of socket access from the command line.

RE: Error: Cannot get a connection, pool exhausted
Thanks Steve for quick reply. I will try as you mentioned. The
releaseConnection() method basically what it does is, it will close the
connection.
if (connection_ != null)
connection_.close();

Subject: RE: Error: Cannot get a connection, pool exhausted
IMHO I would say that you just need to rearrange your code a little - I
would move some code that you have in the try{} block to a finally{} block,
so that it gets executed whether or not there is an error. At the moment,
the section
rs.close();
pstmt.close();
// can relese connection now
releaseConnection();
only executes if the main try{} block executed OK. Because there is no
finally{} block to match the main try{}...catch{} construct, the rs and
pstmt objects do not get cleaned up.
I include a suggested alternative version below. I haven't compiled and run
it but you'll see what I've rearranged.
Your idea of nesting try/catch/finally inside the catch block, and testing
for null before calling close(), is a sound one. I've shown below a slightly
more long-winded version of that below. The idea of it is that if cleanup
of any one resource object fails when the cleanup method (close or
releaseConnection) is called, the code still continues, and attempts to
clean up the other resources, to make sure that as far as possible, no
resources are ever left hanging. Using 4 separate t/c/f constructs like
this is a but repetitive, but if you only have one t/c/f wrapped around the
4 cleanup calls, an exception from the first, second or third call will
prevent the calls that follow it from running. Some might argue that this
is overkill. All I can say is that I always code like this and it works :)
I have left in the call to releaseConnection() in the main finally{} block,
although I'm not sure what that does. I'll leave that to you to decide.
public java.util.Vector getYears(String teamId) throws DAOException
{
java.sql.ResultSet rs = null;
java.sql.Connection conn = null;
java.sql.PreparedStatement pstmt = null;
try
{
// code in this block will complete as
// long as there are no errors
// therefore the only code to go here
// is that which *ONLY* needs to run when all goes OK
// vector to hold result data set
java.util.Vector yearList = new java.util.Vector();
// get connection
conn = getConnection();
pstmt = conn.prepareStatement(yearQueryCommand());
pstmt.setString(1, teamId);
// execute query
rs = pstmt.executeQuery();
// There can be multiple records.
while (rs.next())
{
yearList.addElement(rs.getString(1));
}
return yearList;
}
catch(Exception e)
{
// code in this block only executes if there was a problem
// in the main try block
throw new DAOException(getYears(): Failed to access report
year ! Error: + e.getMessage(), e);
}
finally
{
// code in this block always executes,
// whether or not there was an error
try
{
releaseConnection();
}
catch(Exception finEx1)
{/*ignore*/}
if (null != rs)
{
try
{
rs.close();
}
catch(Exception finEx2)

}
rs = null;

tomcat webapps help
Hi, I know that to create the root of a web application, we just have to make a directory in the webapps folder of tomcat and then copy the files in to that directory. but my situation is different, i have these folders which are to be exposed as web applications else where and i need to somehow point to these directories. is there anyway we can do that. may be its simple but im struggling abit to get this straigtened out. thanks in advance Ravi

I had a similar issue, where I wanted to expose a bunch of jpeg files (use thumbails in the normal jsp pages, but hyperlink'd to the full size image - which I did not want to put into the war file) I basically created another web app I created the file .../tomcat/conf/Catalina/localhost/imageData.xml it contains ?xml version='1.0' encoding='utf-8'?
