Nothing is wrong. Tomcat is telling you that it can't find the APR library and so it won't be used. Note that this is an INFO message, not an ERROR. The APR library is a native library that Tomcat can use to do some of its work in native code instead of Java, which usually performs a little better or allows platform-specific capabilities. Not having APR available is not a big deal, so you can ignore this message. If you want to install APR, there is documentation available on the Tomcat website covering that topic. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGevaO9CaO5/Lv0PARAuZMAKCicdCVeeP7SklO3tvxZso7VdxEVgCeLdGw /geWJodzED+2fMtRQER6EE4= =MVR6 -END PGP SIGNATURE- - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Not true. When the .war is located someplace other than the appBase, the name of the .xml file in conf/Catalina/[host] supplies the webapp name, and the docBase attribute specifies the location - completely independent of the app name. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Apologies OK... you cant do it from a WAR, the tomcat WAR deployment seems to ignore contexts and always default to the name of the WAR file. Try it with just one context and you'll see the behaviour. But you can do it from the standalone deployer... ie deploy the war file to any context you want it will require a little ant script.

Re: Multiple Contexts from single WAR
Chris, to get an idea of how you can map with Apache in front of Tomcat, look at this link. http://tomcat.apache.org/connectors-doc-archive/jk2/jk/aphowto.html Its worth a read because often when the site gets bigger, you end up wanting to load balance, or use Apache to serve images so may be useful. Remember the ROOT idea (see other post) eats up space for other web apps. ie if you call the servlet A then a Web app called A is no longer a possibility.

You rename your WebApp to ROOT Make the context path "" (nothing) And then those A,B and C's no longer represent Web Apps, they represent servlets. You can MAP away merrily in web.xml ie /C to servlet A /B to servlet A /C/doSomething to servlet E etc etc etc. maybe depends wot you doing I guess, and if ROOT is yours to take. otherwise little webapps that redirect is another possibility.

Since it doesn't appear to be working, you should try the multiple-WARs approach and see if /that/ works. If multiple WAR files don't work, then you have something else wrong in your configuration, and your multiply-deployed-WAR strategy might still be viable. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGevgJ9CaO5/Lv0PARAnMvAKCEWbUSj9IPRvtux8zUZ6NVtzYZsQCgkop+ cn+smsqQ8UYMHZmajuQH9sQ= =5g7s -END PGP SIGNATURE- - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Comet example Tomcat 6 not working.
There have been a lot of things fixed and enhanced in the Comet area
since version 6.0.10.
You should better try with version 6.0.13.

Re: using mod_jk: how to set content-type
You know I just had another thought yes it happens sometimes. I have a feeling you doing html parsing, and just wanted to say that it depends very much on how well that 3rd party servlet does XHTML... probably badly ie little all over the place which will make the XML parser you using throw it out.

Re: using mod_jk: how to set content-type
Had a smiliar problem here.
When using mod_jk, apache does not touch the headers created by Tomcat.
Solution:
I wrote a filter that changed the headers after returning from Tomcat
and installed this filter into Tomcat.

Re: using mod_jk: how to set content-type
Thanks for the quick reply, Rainer. Yes a servlet filter makes sense, though not as easy as a one-liner httpd directive. I guess my immediate response is surprise that (since this must be a common problem with so many poorly written web-clients doing content-negotiation so badly out in the big-wide-web) that there aren't any stock servlet filters already written that I can use "out of the box". Does anyone know of any? I will try the experiment of writing a servlet filter (it will do me good to learn all this, and I can imagine other useful things I might do) and if I get something that might be useful for others I will let you know.

Re: using mod_jk: how to set content-type
Dont know Apache in that detail, possibly a guru maybe able to fix the way you attempting, but I think it should be relatively easy to add a filter to tomcat to do that there you can intercept both request and response. ie intercept the request, if browser let it go, if XSLT engine, pretent to be XML.

Re: using mod_jk: how to set content-type
I had a similar problem with mod_prox and mod_headers for Apache httpd 2.2 today, and I would expect, that changing the headers with mod_header does not work. I see no easy way (but maybe others out there). You could hack ajp_unmarshal_response() in common/jk_ajp_common.c. Alternative: experiment with a servlet filter for Tomcat. You can always add filters to webapps without changing or even having the webapp code itself.

Re: Two IIS web servers
Phi-Long LE wrote: Ian, reading optional directives you should probably use the worker.xxx.method, its value is Request, session, traffic or busyness Default is request. For most use cases this should work best. How does it work? 1) Multiple Web server instances do not share any information about load. So they decide completely independently. 2) request method: mod_jk counts the requests going to each worker and whenever a request has no session associated it chooses the worker with the smallest number. The first request after every 60 seconds will trigger a maintenance cycle, which divides all counters by 2, such that historic data gets less important. If you use load factors, the counters get adjusted by the load factors. Bigger load factors will result in bigger load (and smaller increments to the counters). 3) If a worker comes back after error, it will start with the biggest of the actual counters, to prevent it from getting a request storm. 4) busyness method: this looks at the number of request which are actually in the middle of processing. Could be OK for download sites, but usually does not work that well. Especially bad, if your side is not high traffic. 5) traffic: the same as request method, but counts bytes transferred instead of requests done. The bytes are only added after the requests have finished, so if you have long running downloads, the byte counters will ot change for a long time and then change a lot. Having multiple instances work independently should be no problem, if statistics count: this means: you have a lot of traffic, and the percentage of requests without sessions is not too small. In other words: you have a lot of users and the sessions are not taking to long. Load balancing might run into asymmetries, if you have very long lasting in house sessions and very different types of users. Then some heavily used sessions might produce the most load. On the other hand: as long as you only operate two backends, the quality of the load balancing might not be very important, because out of availybility considerations usually one of the two nodes should be able to handle the maximum load. :) Regards, Rainer Le 21/06/2007 16:00, Ian Buzer a écrit : Thanks for that Rainer. How about when a new session comes in?

No X509Certificate Attribute In IIS Redirected Request
Hi, I'm using: IIS V6.0 JK 1.2.23 Tomcat 6.0.13 No X509Certificate attribute is present in the request header received by my servlet when using Client Authenticated SLL with IIS6 and JK1. If I use Apache 2.2 with the mod_proxy modules it works fine. Is this a bug? If so, in what... IIS or JK1? Does anyone know of a workaround? Will JK2 fix my problem? My customer must use IIS... so replacing with Apache is not an option. :-( TIA Simon Temple - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Configuring Tomcat 5.5 to use unicast membership discovery
Hello everyone, Is it possible to configuring Tomcat 5.5 to use unicast for the membership discovery mechanism rather than multicast? I have read through both the Tomcat Clustering/Session Replication (http://tomcat.apache.org/tomcat-5.5-doc/cluster-howto.html) and Configuration Reference (http://tomcat.apache.org/tomcat-5.5-doc/config/index.html), but the only examples presented use multicasting. The reason I ask is because we need to replicate between three sites where one of the sites isn't within the campus network making multicasting difficult.

Re: Configuring Tomcat 5.5 and IIS 6
404's indicate that the file can't be found. IIS needs to be able to "see" the tomcat files/folders in order to know to invoke tomcat.. IIS can't magically see Tomcat's folders, so you may need to define a virtual folder in IIS to the Tomcat JSP files. Have a look at http://www.innotechcg.com/downloads/IntegrateTomcatIIS.zip, which is a step-by-step discussion of integrating IIS 6 and Tomcat. It may not suit your specific need, but if you follow the steps, it should illustrate the concepts required for IIS and Tomcat to work together. My how-to will work with both the default and specific IIS instances. Regards, Glenn rcgeorge23 wrote: > > Hi All, > > I'm having trouble getting Tomcat to serve pages through IIS.

Hi All
Anyone knows how to deal with null values in JDBC ResultSet??
I am trying to render a table in jsp page that read its value from the
database, sometimes, the database returns null values, and so, the whole
table couldn't be rendered. Is there any way to deal with null values.
The correct way to detect nulls in a JDBC ResultSet is rather different from
the replies you've had so far. You should detect the presence of nulls in a
given result set row by using the ResultSet.isNull() method.
So, let's say that we have a result set called 'rs' (you will probably have
used a Statement or PreparedStatement or some other technique to get your
result set from the database):
Statement stmt = ; //an arbitrary Statement object
ResultSet rs = stmt.executeQuery("select employee_number, last_name,
first_name, middle_initial from employee_table");
Now, on to the matter of nulls. Let's say that you are working your way
through your ResultSet. As you know, you get the rows of the ResultSet one
row at a time, using the next() method, as follows:
while (rs.next()) { //as long as there are rows in the result set
//handle one row of the result set
}
Within the while loop, each iteration of the loop will handle one complete
row of the result set.
Let's assume you don't know which columns of the result set are null and you
want to display the values in each column of the result set exactly as they
appear in the result set, except that when the value is null, you want to
display the word "unknown". Here's what you would need to do:
String empno = null;
String lastname = null;
String firstname = null;
String midinit = null;
while (rs.next()) {
empno = rs.getString("employee_number"); //get the employee number
from this row of the result set
if (rs.wasNull()) { //if the employee number is null
System.out.println("Employee Number is unknown");
}
else {
System.out.println("Employee Number is " + empno);
}
lastname = rs.getString("last_name"); //get the last name from this
row of the result set
if (rs.wasNull()) { //if the last name is null
System.out.println("Last Name is unknown");
}
else {
System.out.println("Last Name is " + lastname);
}
firstname = rs.getString("first_name"); //get the first name from
this row of the result set
if (rs.wasNull()) { //if the first name is null
System.out.println("First Name is unknown");
}
else {
System.out.println("First Name is " + firstname);
}
midinit = rs.getString("middle_initial"); //get the middle initial
from this row of the result set
if (rs.wasNull()) { //if the middle initial is null
System.out.println("Middle Initial is unknown");
}
else {
System.out.println("Middle Initial is " + midinit);
}
}
Although this example uses only result set columns that are being stored in
Strings, the technique differs very little for non-text data. Let's say that
we had a column called annual_salary in our result set, where the
annual_salary was an integer containing the number of dollars that the
person earned per year. Let's assume that some people are still negotiating
their salaries so that the salary is stored as null for those people until
the salary has been fully agreed.. The technique to handle the salary would
look like this:
int salary = null;
while (rs.next()) {
salary = getInt("annual_salary"); //get the salary from this row of
the result set
if (rs.isNull()) { //if the salary is null
System.out.println("Annual Salary is unknown");
}
else {
System.out.println("Annual Salary is " + salary);
}
I hope this helps you with your null handling!

Re: Null
There is an ISNULL function in Transact SQL and a NVL function in PL/SQL that will return a default value if the data is null. That is if you don't mind writing separate SQL for each database.

Two IIS web servers
Hi, I currently have one IIS server balancing requests to two Tomcats using JK 1.2. I am using JK to provide sticky sessions and all is working well. I would like to be able share requests across a second IIS server, however I am unable to create sticky sessions at the web server level so requests could go to either web server. My question is, if I point both IIS servers to both Tomcats, will this work correctly? Will the sessions still get directed to the correct Tomcat, and will the two JKs still be able to choose the best worker for new sessions?

Re: Null
Mohammed, While it may not work in all browsers, you can try the "empty-cells" CSS property in the table's style. Render the table tag thusly: ... An alternative is what the other guy said; simply check for nulls before rendering, and render a non-breaking space if you have a null. I'd shoot for using EL rather than pure java for that though. Good luck! Brantley Mohammed Zabin wrote: Hi All Anyone knows how to deal with null values in JDBC ResultSet??

The syntax below is correct. There must be something else syntactically

Re: Error while starting the Tomcat
WEB-INF\lib\servlet-api.jar The Tomcat Libs are getting into your web-app they must not. When you make a servlet, you will see that it adds a folder to your libs Tomcat5.5 or whatever. Its special, because it allows you do write code and debug, but it actually never puts them into the web/libs. Its kinda like, the servlet app just borrows a piece of Tomcat, so you can write your code. I think whats happened is somewhere, you may have deleted that special folder and then, it complained, and you added the class in. But now Tomcat is effectively trying to load itself from your web app You need to take those libs out of your lib, and I have no idea how, but I think if you just swap from say the external tomcat to the internal tomcat, in right click->properties->run it may put that special folder back.

Hi Mohammed This isn't the best forum to ask this kind of question : try something like http://www.javaranch.com/, you'll get good answers from there. As an interim, check for null values before attempting to display any value. Something like Jakarta commons StringUtils package is a big help in keeping your code tidy : <%= StringUtils.isBlank(master.getHeatLog()) ?

Comet feature in Tomcat
I'm very interested in Comet features added in Tomcat 6. But I don't know how to use it. Could anybody give me a HelloWorld example of it? Thank you!
Comet example Tomcat 6 not working.
Hi,
I am trying to run the comet sample given along with tomcat. The sample is
not working correctly most of the time. I am using NIO connectors and Tomcat
version is 6.0.10.
I have some doubts also:
1) In the ChatServer example, a thread (using a Runnable MessageSender) is
sending responses the clients. Is it possible to write multiple times to the
same response. Because when we do writer.flush() then that response is sent
to the client.
2) The READ event is never invoked in my example. whenever I send a request
only BEGIN event is getting called. I thought, for the first time only BEGIN
event should get called, and for further requests by the same client, READ
event should get called.
3) I am getting exception at the line where the thread which is trying to
write to response stream is calling the flush method.
The code (from tomcat example) is:
for (int i = 0; i < connections.size(); i++) {
try {
PrintWriter writer =
connections.get(i).getWriter();
String toBeFlushed = "";
for (int j = 0; j < pendingMessages.length; j++)
{
// FIXME: Add HTML filtering
writer.println(pendingMessages[j] +
"");
}
writer.println("Random message 1" + "");
writer.println("Random message 2" + "");
System.out.println("writer will flush now.
writer is null?=" + writer == null);
writer.flush();
} catch (IOException e) {
log("IOExeption sending message", e);
}
}
And the error message I am getting is:
Exception in thread "MessageSender[/CometTestApp]"
