Re: Problems running pre-compiled JSP classes when in subdirectories
The generated servlets are not put in a package. When Tomcat is compiling JSP it is put in org.apache.jsp. How to set this in the jspc task. The files are generated as usual in the work directory in the same structure as Tomcat itself compiles JSP files. Not entirely true. You can compile the java sources of the JSP's yourself. I do it and it prevents the delay (for Tomcat to compile it) when you first execute a JSP. You also pick up any possible JSP errors when building, not after deployment. You can also specify *any* package, it doesn't have to be org.apache.jsp... I eg use com.myapp.jsp The Tomcat HOW-TO documentation has a good example of the complete process. Jasper 2 JSP Engine How To, option Web Application Compilation. I followed it exactly and mine works 100%. The main difference from what you guys explain (I think), is that I do not only generate java sources for the jsp's, but also compile them (my jsp's are thus delivered as .class files) and also include the servlet mappings in the web.xml. Its all very easy to do with ant.

Re: Tomcat stops handling HTTP connections, socket is SYN_RECV
On Wed, Jan 07, 2004 at 21:00:30 +0100, Antonio Fiol Bonnín wrote: I have not read through all the thread, so maybe I am repeating something. If so, sorry about being lazy. You seem to be hitting maxProcessors. If you do, no more threads are created, and connections start getting into SYN_RECV state, simply because Tomcat is not accept()ing them, exactly as you told it to do. So, either reduce your concurrency level for the tests, or increase maxProcessors. Actually, I don't think I'm hitting maxProcessors - usually when that happens, you only get an error message about no more threads being available in the pool. Here, the issue is that Java is unable to create a new native thread and therefore throws an OutOfMemoryError. So the problem is that even after the tests are complete and there are no active connections at all, it's no longer possible to connect. I think perhaps the OutOfMemoryError causes whatever thread is accept()ing new http connections to die. - Frode - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Problem with embedded Tomcat and JSP compilation.
Hi,
I wrote an application running an embedded Tomcat, based on the sample code of the
onJava site (an org.apache.catalina.startup.Embedded class with manual configuration
of things usually found in server.xml). I use Tomcat 4.1.27 and Java 1.3.1.
Tomcat starts well, but is not able to compile JSP page. It displays the following
error:
code
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 4 in the jsp file: /index.jsp
Generated servlet error:
[javac] Compiling 1 source file
C:\test\tomcat\work\_\localhost\_\index_jsp.java:3: package javax.servlet does not
exist
import javax.servlet.*;
^
...
/code
and so on for all import statements. It looks like a classpath problem, but I set the
classpath with all the jar files in tomcat/common/lib, in tomcat/server/lib, in
tomcat/common/endorsed, bootstrap.jar, the tools.jar of java. I set it in the
environment CLASSPATH variable and in the classpath of the jar of my application. And
the classpath is set, because if not, Tomcat cannot be launched.
So I probably missed something, but what?
Below you can see the code of my class and the code of the main function:

japanese download filename
Hello,
(B
(BI've got a servlet that allows users to download files. I'm specifying
(Bthe filename using the Content-Disposition header, and the charset using
(Bthe Content-Type header. It all works lovely when the filename is English
(B- but not with Japanese.
(B
(BI got the following to work with the latest version of IE:
(B
(B encodeFileName = URLEncoder.encode(fileName, "UTF-8");
(B response.setContentType("application/octet-stream"); // ie doesn't
(Bseem to need the charset if it's utf-8
(B response.setHeader("Content-Disposition", "attachment; filename=\""
(B+ encodeFileName + "\"");
(B
(BThis, however, does not work with Netscape, nor does it work with older
(Bversions of IE (the name displays as escaped unicode).
(BI need to support NE and IE (recent versions) on both Windows and Mac.
(B
(BI played around with the headers for Netscape and tried everything I could
(Bthink of, to no avail.
(BI then used a packet sniffer to checkout the headers from a different
(Bapplication (PHP based)
(Bthat works properly with Netscape - but even after I managed to get the
(Bheaders for Content-Type AND Content-Disposition
(Bto match, it still didn't work (the action name shows up instead of the
(Bjapanese file name).
(B
(BHere are the settings I used to get the headers to match - the file name
(Bencoding matches byte for byte with the PHP app:
(B encodeFileName = new String(fileName.getBytes("Shift_JIS"),
(B"ISO-8859-1");
(B response.setContentType("application/octet-stream; charset=Shift_JIS");
(B response.setHeader("Content-Disposition", "filename="
(B+ encodeFileName);
(B
(Bfor a file name PC$B4IM}(B.xls I get a filename=PC\212\307\227\235.xls in the
(Bheader, which looks good to me.
(B
(BHere are the (relevant) headers from the PHP app, which works fine (it's
(Bclosed source, so no luck there):
(BContent-Disposition: filename=PC\212\307\227\235.xls\r\n
(BContent-Type: application/octet-stream; charset=Shift_JIS\r\n
(B
(B
(B
(BI'm at a total loss. I've tried every charset, leaving OUT the charset,
(Bsurrounding the filename in quotes, standing on my head... I stumbled
(Bacross this tomcat bug
(B(http://nagoya.apache.org/bugzilla/show_bug.cgi?id=24380) but the header
(Bencoding appears to be coming out ok. I tried tomcat 4.0.6 for the hell
(Bof it but that, of course, did not work either.
(B
(BIs it possible that NS is ignoring the specified charset, and trying to
(Bget it from the data stream?
(BIf the headers are a match, what else could be happening? Are there other
(Bheaders besides Content-Type and Content-Disposition that I should be
(Bworrying about?
(B
(BOne (slightly) strange thing is that my packet sniffer seems to
(Bautomatically recognize the PHP app's packets at HTTP, but not the servlet
(Bapp's packets (have to click the "decode as html" button).
(B
(BAny help, ideas, suggestions, or prayers would be most welcome.
(B

criteria for a session
Hi, what are the criteria for tomcat 4.1.26 to say the session is null (((HttpServletRequest)request).getSession(false))? It seams to depend on something in the request. When i open a second new IE Window, not a child from the first IE Window, the session is null. I dontt call session.invalidate() and the timeout is not reached.

Static ints being cached
Hi All, I have an interface containing public final static ints. My servlets reference these ints when making database inserts. Yesterday I reordered the values of the ints and noticed that old values were still being placed into the database. I guess this was somehow a caching problem. I deleted the .class from Tomcat to ensure a recompile would place a new .class and restarted Tomcat, but old values still went in the database! - If I output the static ints from a JSP the new values come out. - If I output the static ints from a class the old values come out. - If I force the class using the interface to recompile, then the class starts using the new values It seems that somehow references are being stored by Tomcat somewhere since a restart does not work but I don't know much about this. I would like to trust that when I change values that Tomcat is able to pick these up, at the very least on a restart!! I don't want to go through recompiling my whole app. I am using Ant in a multi-developer environment to compile and it compiles only classes that have changed. I cannot recompile the whole app everytime I change constant values. Help and understanding appreciated ... Cheers, ADC FONT SIZE=1 FACE=VERDANA,ARIAL COLOR=BLUE --- QAS Ltd.

Hi I cannot recompile the whole app everytime I change constant values. This is the problem. public final static ints are not referenced by the compiler but placed inside the class files as constants as far as I know. Therefor, the value is in every class file which uses those.

I could not tell you whether that is a good or bad statistic for a 2 man development Tomcat that uses database pooling to SQL Server, Struts and a Content Management System. I don't consider what we are doing to be overly complicated. However, when we get to lauch to 300 people, I am a little nervous that we will hit OutOfMemory within seconds. Our Tomcat 5 loads itself by default at around 30MB. When the first hit to the web application goes in it leaps by 2-3 MB. Then each subsequent request seems to cost about 50-100K for just moving around. There are not many session objects being stored. The memory increases all the time and very rarely drops. Last night when we left it stood at 70MB and coming in this morning it was still 70MB. Would anyone be kind enough to provide some tips on how to analyse this problem or what it might be even with the view to a 300 user burdon being placed on Tomcat. Is Tomcat even supposed to be able to handle 300 users? Are there any good sources of information on the web relating to tuning Tomcat or its performance - I have looked around but could not find anything definitive.

RE: criteria for a session
I thought sessions were essentially browser sessions. For anything I've done that requires knowledge of user state between different browsers (but same machine) I've used cookies to save some form of user id. I did turn on the Tomcat setting for persistent sessions and found that preserved session in the same browser with a Tomcat reboot. I guess you could serialise sessions to a DB and retrieve from user id in a cookie - or am I losing the plot now? Best regards Chris what are the criteria for tomcat 4.1.26 to say the session is null (((HttpServletRequest)request).getSession(false))? It seams to depend on something in the request. When i open a second new IE Window, not a child from the first IE Window, the session is null. I dontt call session.invalidate() and the timeout is not reached. I know that there are only two reasons for invalidate a session. 1) session.invalidate(); 2) session timeout I thought these where the only reasons.

You are using a SUN Jvm, with no Xms nor Xmx parameter.

Squid with ESI + Tomcat
Hi all I'm trying to use squid as a reverse proxy in front of Tomcat and to make things more complicated squid is compiled with ESI enabled :-) I've allready convinced squid-tomcat dou to process basic esi example but squid doesn't cache anything. I suspect that it's because of http headers that Tomcat by default adds to each response. I tried similar configuration with Apache and everything works promising ;-) So the question is how to remove Pragma, Cache-control and Expires http headers? -- Regards Konrad - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Tomcat 5 is not generating IOException when connection closes
I have a servlet with a persistent connection open to a client
(browser), and when the browser is closed or the user hits the stop
button, the connection is closed, but the servlet isn't throwing the
IOException when it should do it.
(i guess)
As i could notice, after about 8k of data being written to the client
after the connection has been closed, the serlet gets the IOException.
I think that perhaps tomcat is buffering the data and only when this
buffer is full the IOException is thrown, even when we make a explicit
call to out.flush().
The strange thing is that when the connection is open, the client
receives data in real time, with no buffering or very little buffering.
Has anyone ever had this problem? I tried to call the method
response.setBufferSize(0), but it didn't work.
Below is the piece of code that writes the data to the ServletOutputStream.
ServletOutputStream out = response.getOutputStream();
public void send(String s) throws IOException {
out.write(s.getBytes(), 0, s.length());
out.flush();
}
thanks in advance,
Paulo

RE: Connection Pooling
Justin, The DBCP that's bundled with Tomcat as well as most other pools (proxool for one) return a java.sql.Connection implementation class that wraps the actual DB driver java.sql.Connection implementation. Calling close() on the Connection that you got from the pool returns the underlying connection to the pool for reuse. For DBCP, if you don't call close(), the connection is eventually considered abandoned, and there are a few configuration parameters that affect what happens at that point. http://jakarta.apache.org/commons/dbcp/ for details. -john. -Original Message- From: James Neville [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 07, 2004 11:51 AM To: Tomcat Users List Subject: Re: Connection Pooling Justin, That would all depend on the pooling implementation you're using. Commonly, its pool.free(conn) or pool.freeConnection(conn). Remember *not* to close the connection if you're using connection pooling, as this should be handled by the pool itself. That said one of my colleagues mentioned one pooling implementation he used that returned a custom connection object when obtained from the pool (ie not a java.sql Connection object). The close() method on that connection returned it to the pool, but *didn't* actually close it. If you let us know which pooling implementation you're using, it may make things clearer ;) Cheers, James Hart, Justin wrote: Is there some manner in which a database connection should be returned to the connection pool, or is that automatic?

Re: Tomcat 5 is not generating IOException when connection closes
What do you mean by ok?
As far as i can see, the connection closes and writing data to the
OutputStream should generate an IOException, but this isn't happening... :-(
The problem is that my servlet is inside a loop, and needs to know when
the client closes the connection, so it can exit the loop and properly
close the running thread and liberate memory and cpu resources.
If you say it's ok, it means that tomcat really buffers the data and
only generate the IOException when this buffer is full, and that this
behavior is ok.
Is there any way i can control this tomcat's behaviour, like reduce the
size of the buffer? Or even disable this buffer? (better)
thanks!

Re: Problems running pre-compiled JSP classes when in subdirectories
The problem is when files are kept in work directory. I dont want to put the generated files in web-inf\classes and add mapping. My purpose is to compile jsp pages as part of a build before the application is given for testing. I will keep files in work directory. This I have to do frequently and I want to detect any compilation errors and make it faster for the QA fellow to access the application.

When Tomcat is compiling JSP it is put in org.apache.jsp. How to set this in the jspc task. The files are generated as usual in the work directory in the same structure as Tomcat itself compiles JSP files. Not entirely true. You can compile the java sources of the JSP's yourself. I do it and it prevents the delay (for Tomcat to compile it) when you first execute a JSP. You also pick up any possible JSP errors when building, not after deployment. You can also specify *any* package, it doesn't have to be org.apache.jsp... I eg use com.myapp.jsp The Tomcat HOW-TO documentation has a good example of the complete process. Jasper 2 JSP Engine How To, option Web Application Compilation. I followed it exactly and mine works 100%. The main difference from what you guys explain (I think), is that I do not only generate java sources for the jsp's, but also compile them (my jsp's are thus delivered as .class files) and also include the servlet mappings in the web.xml.

Problem with Web app, javax.print, SecurityManager, and printer discovery
I'm running a Web app that uses the javax.print API to do discovery on attached printers and passes a java.util.List of names to a JSP to display to clients in an HTML select box . I'm running under Tomcat 4.1.29 on Windows 2000 SP 4 and Sun's JDK 1.4.1_03. The drop-down list box is empty - no printers were found. I have three attached printers, so I know the list box should not be empty. I have a Command class that gets all the available printers. The pertinent lines are: List availablePrinters = new ArrayList(); SecurityManager securityGuard = System.getSecurityManager(); if (securityGuard != null) securityGuard.checkPrintJobAccess(); else System.out.println(No security guard; could not check print job access); PrintService [] ps = PrintServiceLookup.lookupPrintServices(DocFlavor.INPUT_STREAM.AUTOSENSE, null); I put some print statements into the code so I could see what was happening. I get this out in the log file: No security guard; could not check print job accessFound zero available printers If I take this code and run it in a desktop app I get back three printers and I can print to my default printer without a problem. I KNOW that I ran this app on Tomcat 4.1.24 and saw printers in the drop-down. I downloaded and tried running the app under the older version of Tomcat, but it, too, shows an empty drop-down. My notes aren't telling me what I did to allow printer discovery. Can anyone refresh my memory? Thanks - MOD __ Do you Yahoo!? Yahoo!

On Unix you can also use the truss command to attach to a running process (check Google for examples). I used this technique on a web application and discovered that a file with *static* content was being opened 1,000 times per hour by the application. Before I showed up at the company, everybody was working on NT and basically hated Unix, so the problem went undiscovered for close to four years. AFAIK, most (all?) of the Java-based tools would not detect this sort of problem. I don't think truss is available on NT, even with the MKS (or equivalent) package. For people who are on NT and are experiencing problems with their Java-based web- application, I would strongly recommend setting up a Unix environment to perform truss-based testing (even if you need to hire a contractor to set up everything). It's really quite amazing what truss can uncover:) Cordially, Oswald Edson Alves Pereira [EMAIL PROTECTED] wrote: JProfiler is the best for this job, there are examples to show you how bind JProfiler to tomcat ( www.jprofiler.com ), its pretty easy to handle this tool. -- De: Allistair Crossley[SMTP:[EMAIL PROTECTED] Responder: Tomcat Users List Enviada: quinta-feira, 8 de janeiro de 2004 8:58 Para: Tomcat Users List Assunto: RE: Tomcat OutOfMemory at 158MB - Not reclaiming any memory overnight Yes I would like to profile my applicationbut do you have any tips on how to do this or where to start?

This is our development version of Tomcat. Looking at the Windows processes revealed Tomcat at 158MB. Let me do some divination. You are using a SUN Jvm, with no Xms nor Xmx parameter. So, the memory allocated to your applications is 64MB (default). 158 is a good value reflecting the size of the VM plus the size allocated to your applications. If your application needs more memory, try to path -Xmx=128m -Xms=128m to your startup scripts.

mod_jk2 JNI question for the brave :)
Hi everyone,
Bringing the woes of jk2+JNI again here with the dreaded Can't find child
xx in scoreboard, since I haven't found
a satisfactory answer by anyone.
Using TC5 with Apache 2.0.x under Linux, I can get jk2 to work using
sockets. However the fun begins when
I try to use JNI.
Looking at the source from mod_jk2, I have the following snippet:
workerEnv-childId = find_child_by_pid(proc);
if (workerEnv-childId == -1) {
int max_daemons_limit;
ap_mpm_query(AP_MPMQ_MAX_DAEMONS, max_daemons_limit);
if (max_daemons_limit == 0) {
workerEnv-childId = 0;
env-l-jkLog(env, env-l, JK_LOG_INFO,
jk2_init() Found child %d in scoreboard slot %d\n,
proc.pid, workerEnv-childId);
}
else {
env-l-jkLog(env, env-l, JK_LOG_ERROR,
jk2_init() Can't find child %d in scoreboard\n,
proc.pid);
workerEnv-childId = -2;
}
} else {
env-l-jkLog(env, env-l, JK_LOG_INFO,
jk2_init() Found child %d in scoreboard slot %d\n,
proc.pid, workerEnv-childId);
Now, the first line is the line that tries to locate the childId of the
worker in the running
server threads (if I am not mistaken). find_child_by_pid will loop through
all the active servers
trying to find the pid passed as an argument, if it fails to do so it
returns -1.
I am hazarding a guess, by saying that it must be something in my
configuration, within workers2.properties.
Is there anyone out there who can provide the definitive configuration file
and/or guidelines for workers2.properties?
The documentation on jk2 at the mo is a pile of poo (sorry guys).
Have a nice day,
Yiannis

RE: Tomcat OutOfMemory at 158MB - Not reclaiming any memory overnight
Howdy, JProfiler is one option, there are many others. I use OptimizeIt on a regular basis. How to profile? Umm, that's a bit of a black art. Basically, start the profiler following its documentation on how to tie it into your tomcat process. You will see where CPU time is spent and where memory is allocated. Look for unnecessary allocations (why do I still have 20 instance of foo.bar around, they should all be gone by now...) and overly heavy methods (how come foo.bar.getX is taking 5 seconds, it's a simple read operation). Profiling and memory tuning go hand in hand. You will go through several iterations of playing with the Java VM Options before you settle on the optimal one. Can tomcat handle 300 users? Sure, depending on your hardware and your webapps. This is why you stress-test your app with a tool like JMeter that can simulate 300 users hitting your site. Let me do some divination. You are using a SUN Jvm, with no Xms nor Xmx parameter. So, the memory allocated to your applications is 64MB (default). 158 is a good value reflecting the size of the VM plus the size allocated to your applications. Umm, no. 64MB is the default heap which includes the VM and your applications. At that size, VM stack/symbol table overhead is far less than 64MB, and so the total process resident size would not be 158MB unless other wacky things were going on. But anyways, my point is that whatever you specify in -Xmx is total for the JVM's heap, which includes its own objects as well as your applications, not just your applications. And another basic note on JVM memory usage: it will never go down overnight. The JVM allocates memory as needed (by default, this can be changed using parameters like -Xms), and will not release that memory back to the operating system, ever. It'll release the memory back into its own heap, but it will stay tied to the JVM process. JVM process memory is monotonically increasing in the strict mathematical sense of the term.

RE: Retrieving the context path from a standalone class
Howdy,
One way is by taking advantage of Tomcat's naming conventions with the
tempdir
String tempdir =
+ context.getAttribute(javax.servlet.context.tempdir);
int lastSlash = tempdir.lastIndexOf(File.separator);
if ((tempdir.length() - 1) lastSlash) {
logHomePropName = tempdir.substring(lastSlash + 1) +
.log.home;
}
Very tomcat-specific and subject to change ;) But the 2nd approach is
much better, as I mentioned using ServletContext#getResource is a good
way to go. As I was reading the code, I could swear I'd seen it before,
and then I realized it's a paste from the log4j repository selector you
wrote ;) (BTW how come we haven't moved it from log4j-sandbox to log4j
for 1.3 yet?)

RE: Tomcat maximum heap size on Linux
Howdy, I've seen this answer twice today, make scripts to stress-test your app. How do you do that? What am I connecting to and looking for in a script that stress-tests a Java servlet or web app? I'm only asking because I'm a little green at this and there are obviously other people with the same needs who are failing to do this preemptively. Twice today, hundreds of times in the archives ;) This is a standard process which can be summarized as follows? - How many maximum concurrent users to you need to support? (e.g. 100). - When handling that expected maximum number, what is the acceptable response time for pages in your application (e.g. 5sec). - Now get a tool like JMeter (which I like a lot, because it's free, powerful, and contains great tidbits from my friend and fellow developer Peter Lin [http://jakarta.apache.org/tomcat/articles/performance.pdf]) or Apache AB and write a script to simulate that expected maximum number of users hitting your webapp. - Run the script and see how your webapp responds. Are there crashes or other errors in the log? Is the response time too slow? - If all works well, you rock. Otherwise, inspect your webapp, perhaps running it with a profiler, for ways to improve performance. You will most likely need to experiment with Java VM Options, perhaps hardware or OS-level tweaking as well. Repeat the process until you're satisfied with performance. That's it. If you're stuck at any step in the process feel free to ask for help. I can't make this a complete message without stressing, yet again, that anyone who says they put apache in front of tomcat because tomcat's standalone performance isn't good enough without having done the above analysis should be fired on the spot.

RE: Retrieving the context path from a standalone class
Howdy, If it isn't then I want to know the correct way to deal with the problem. Can you restate your problem? If I remember correctly, it was that you need to index your site using lucene upon tomcat startup. You don't want to wait for the first user request because you don't want that request to have to wait for indexing. Is that right? The only thing I didn't understand in your email was the comment re docBase. I'm not sure what this is - in particular, are you talking HTML document base or some other mechanism - can you enlighten me? The docBase is the root directory of your webapplication, i.e. /contextPath/. It's not the same as the root directory of the server usually, only in the special case where contextPath is the empty string. All ServletContext#getResource and getRequestDispatcher calls are relative to this docBase rather than the server root, and therefore you don't need to know the context path in order to use these function calls. Actually I just thought of another argument for supplying deployment information to the developer - feel free to shoot me down. In my web app I have a filter called ProtocolFilter. It simply switches the client in and out of SSL as specified by filter options. In order to perform the switch, the ports must be known. I currently have these ports defined as env entries so that the filter (and other code) can pick them up. How else could I possibly do this? Using the redirectPort attribute of tomcat's Connector element in server.xml. I took a look at lucene's indexing code. It seems like you can construct an Analyzer from a Reader (so an InputStreamReader constructed from the InputStream returned by ServletContext#getResourceAsStream would work), and then use a RAMDirectory as the IndexWriter's Directory argument. Alternatively you an use an FSDirectory if you want to save the index to disk, use the one directory where the container will let you write, the directory accessible via (File) servletContext.getAttribute(javax.servlet.context.tempdir); That should work, no?

RE: weird tomcat questions
Howdy, * How does scoping work in Tomcat? The same as in all java programs. * Why would you bother using a singleton when you're working with Tomcat? Why would scoping be different in tomcat than any other servlet-complying container? What does a singleton have to do with a web container? You would use a singleton in tomcat for the same reasons you would in other programs. One advantage a singleton has in a servlet container like tomcat is that all the webapps run in one JVM but their own classloaders, with one common parent classloader. If your singleton is in that classloader (the shared or common classloader in tomcat parlance) then all your webapps see the same instance of this singleton, thereby making it a suitable location to place objects that you want to share across webapps.

Hi all I'm trying to use squid as a reverse proxy in front of Tomcat and to make things more complicated squid is compiled with ESI enabled :-) I've allready convinced squid-tomcat dou to process basic esi example but squid doesn't cache anything.

RE: Retrieving the context path from a standalone class
Quoting Shapira, Yoav [EMAIL PROTECTED]:
Howdy,
One way is by taking advantage of Tomcat's naming conventions with the
tempdir
String tempdir =
+ context.getAttribute(javax.servlet.context.tempdir);
int lastSlash = tempdir.lastIndexOf(File.separator);
if ((tempdir.length() - 1) lastSlash) {
logHomePropName = tempdir.substring(lastSlash + 1) +
.log.home;
}
Very tomcat-specific and subject to change ;)
Yep, that's why I don't use that anymore and use the second approach.
But the 2nd approach is
much better, as I mentioned using ServletContext#getResource is a good
way to go. As I was reading the code, I could swear I'd seen it before,
and then I realized it's a paste from the log4j repository selector you
wrote ;)
Yes, with your help :-)
(BTW how come we haven't moved it from log4j-sandbox to log4j
for 1.3 yet?)
Not sure, but we will probably want to update it to work with Ceki's new
configuration mechanism which is to replace the DOMConfigurator (what was it
called again?) and also use the new watchdogs instead of configureAndWatch()
(which is only used in cases where it is configured to be used *and* we detect
that we have file system access to the configured [proposed] location of the
log file). However, I am unfamiliar with how these work, so any help on this
effort would be appreciated.
For my purposes, I use a jar built off the unofficial 0.2 tagged version of the
log4j-sandbox CVS code. BTW, ContextJNDISelector has been moved to Log4j
already. I think we should also move the other optional appenders as well as
the configuration stuff as they have been very useful (to me, at least). I'd
like to hear the opinions of some of the other developers on this before an
alpha release of log4j-1.3.

Conn.Pooling stopped Tomcat from starting at boot time
Hi, I implemented connection pooling for Tomcat 4.0 and it works fine. The only thing is Tomcat is not starting at boot time anymore. Any reason for that? How can I correct it? Also, what should I do to start Tomcat 5.0.16 at boot time on my other machine? Thanks N.K. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: mod_jk2 JNI question for the brave :)
Hi Mladen, thank you for the reply that helps me gain some understanding in the issue. Would it not be possible to bind JNI under a single worker and then isolate that worker from the rest of the pool (possibly provide the ability for workers to carry some sort of identification bit with regards to who can access them)? I'll be more than happy to volunteer for the documentation, just point at the right direction :) Thank you, Yiannis -Original Message- From: Mladen Turk [mailto:[EMAIL PROTECTED] Sent: 08 January 2004 14:48 To: 'Tomcat Users List' Subject: RE: mod_jk2 JNI question for the brave :) From: Yiannis Mavroukakis Subject: mod_jk2 JNI question for the brave :) Hi everyone, Bringing the woes of jk2+JNI again here with the dreaded Can't find child xx in scoreboard, since I haven't found a satisfactory answer by anyone. Using TC5 with Apache 2.0.x under Linux, I can get jk2 to work using sockets. However the fun begins when I try to use JNI. Looking at the source from mod_jk2, I have the following snippet: Since I wrote the code, It would be me to blame :-). The problem with JNI and Linux is that you may have few different mpm's to run. JNI presumes that you have a _single_ worker process with multiple threads. If your mpm behave differently then the JNI isn't the appropriate channel to use. The documentation on jk2 at the mo is a pile of poo (sorry guys). I agree with you. Do you volunteer?

Possible Bug in 4.1.27 - RequestDispatcher fails after cross context include
I have two web applications, client and server (attached). In the client web application, there is a single servlet, ClientServlet which performs an include to another servlet, ServerServlet, in server web application. This is done through the following code: ServletContext serverServletContext = getServletContext().getContext(SERVER_CONTEXT_ROOT); RequestDispatcher requestDispatcher = serverServletContext.getRequestDispatcher(SERVER_SERVLET_PATH); requestDispatcher.include(httpServletRequest, httpServletResponse); This portion of the test case works as expected. The ServerServlet will then attempt to include a jsp file, test.jsp, within the server web application using the following: RequestDispatcher dispatcher = httpServletRequest.getRequestDispatcher (/test.jsp); dispatcher.include(httpServletRequest, httpServletResponse); This, however, does not work as expected. Although the dispatcher is not null, the content of the jsp is not displayed. Note that if you invoke the ServletServlet directly, without going through the ClientServlet of the Client web application, the jsp is displayed as expected. Thoughts?

Re: TC 4.1.12 on Linux - session swapping
They are being posted to the same JSP. There are several beans that are page scope. Think that is it? I have a newer part that was written by me that uses request and session scope beans. I will have the QA person run her tests against that part of the project. I am assuming that this will be OK. If so, I will change the page scope beans to be request scope beans. Hopefully the problem will go away. I had noticed on other servers that if you have a request scope beans and you post back to the same page, you sometimes get back the same request. Usually not a problem, because it is yours. However, if this happens for page scope, then real bad, because everyone uses the page.

I just upgraded a web application from Tomcat 4.0.6/mod_jk 1.2.5 to Tomcat 4.1.29/mod_jk2 2.0.2 (built myself), both on Apache 1.3.27 on Linux. Our webapp runs as the ROOT context (files are in $TOMCAT_HOME/webapps/ROOT). We have precompiled the JSP pages for 4.1.29, but did not do that in 4.0.6. With Tomcat 4.x, you still need to have a physical 'index.jsp' file in the directory, even if you've precompiled it (this is no longer true for Tomcat 5.x). An empty file is good enough. Also, unless you're mapping everything to Tomcat, you need it so that Apache realizes that there is an index file there. On the old setup, to get to our application all you had to do was type https://myserver https://myserver and you'd get index.jsp by default. Now, if you type the URL like that you get a directory listing. You have to explicitly put index.jsp in the URL to get to it. If you do that, the entire web app works just fine. Is there some new configuration item I need to tweak here? I tried adding a segment for welcome-file-list to my web.xml: welcome-file-list welcome-fileindex.jsp/welcome-file /welcome-file-list But it still doesn't work. Any other suggestions would be greatly appreciated. I figured perhaps my workers2.properties was messed up, so I'll put a sample of that below. I made almost no changes at all to server.xml except to add tomcatAuthentication=false for the Coyote connector and to comment out the connector on port 8080.

Thus, if there is a JSP at http://hostname:8080/FOO/bar/Page.jsp http://hostname:8080/FOO/bar/Page.jsp , users can access it by either going to that URL or to this url: http://hostname:8080/bar/Page.jsp http://hostname:8080/bar/Page.jsp . (Where BAR is the name of the webapp). Does anyone know if / how this can be done? I know one can implement such functionality using Valves, but I seek a simpler solution (if there is one).

RE: Making index.jsp work as welcome page after upgrade
Since I'm running with JK2 and went the workers2.properties route to configure it I don't have any JKMount statements anymore (I did with JK). FYI, we're running Apache 1.3.27.

RE: Mapping /BAH/ to /
Howdy, Thanks for the response. How bout if I want the mapping to be for *all* webapps on the appserver? Eg, I want: http://hostname:8080/FOO/bar to map to /bar http://hostname:8080/FOO/sampleWebapp to map to /sampleWebapp http://hostname:8080/FOO/anotherWebapp to map to /anotherWebapp Etc for all webapps in the server. Is this behavior possible? Take a look at the balancer webapp's URLStringMatchRule (Balancer ships with tomcat 5). It's perfect for your needs. You would add the balancer filter to your webapp and add a string match rule to balancer's rules.xml file for every case like the above 3.

RE: Microsoft SQL Server validation query
Thank you to all of you for your quick replies. It seems that the connection pool validation query is not specific to any database server implementation unless the query statement itself is server-specific (that is, it refers to a special server system database, table, or function). I like the idea of querying the server for the date, but I'm not sure that the date function is standard SQL and portable across all server implementations. Does anyone know otherwise?

Migrate Apache+Jserv to Tomcat
Hello. I am trying to migrate a web application from Apache+Jserv to Tomcat. Under Apache/htdocs I have a folder with the index.html and the applet in JAR format. The servlet zone folder contains the zone.properties, the servlets in JAR format and some other classes. How to deploy to Tomcat? I created a new context and copied to the document root all those files, but only the index.html and applets are visible! It seems that the servlets are not running. What are the right steps? Thanks in advance, Regards, Marco Roda

RE: Retrieving the context path from a standalone class
AFAIK there's no way to get the HTML that a JSP page would show without an actual request. Right, which is why we need the context path. I think where we diverge is in our assesment of 'bad practice'. You had mentioned trouble with getRealPath(). Incorrect placement of a method in the API lead to some problems. Was using the API as it stood at the time, a 'bad practice' or was it a bad API decision that lead to problems. I think when something is deprecated, because it's later found out to be 'stoopid' or problematic, that's a bad API that's been fixed. From the API: Deprecated. As of Version 2.1 of the Java Servlet API, use ServletContext.getRealPath(java.lang.String) instead I find it kinda funny it got moved, rather than *re*moved. It's eventual home is more than ironic in the context of this discussion. (If it was in both places, and only one got removed, ignore what I just said). All I'm saying is.. where's the bad practice in trying to obtain a Context path from the ServletContext object? We can already do it from a Request. I agree about the separation of app develop and deployer. The deployer should be able to deploy to ANY context, and we as the developer shouldn't care about where. But that's my point. We don't want to hard code anything, we want to retrieve the appropriate value for one of our processes that *does* care about what the value is. Unless we go through a stupid hack, we're very limited in how we can retrieve this information, run-time. I argue for improved visibility of a method. the hack(s) I've used: Use an init-param, duplicating the information of context path, and no problem, because I'm the deployer AND developer, so I know to set both up correctly. use a starup servlet to request a JSP page. The JSP page now has a Request object. Obtain context path from there, and spin off your standalone class from the JSP. But after all, I've labelled those as 'hack'. It's all solved by having the appropriate method on the appropriate object. But then again, what do I know about it, I'm not part of the JSR, and I haven't been around since before JServ. But of course, this is OT by now, so I promise not to post again on this topic. :) - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
What replaced ApacheConfig in Tomcat 5
I'm trying to get the Automation of my apache mod_jk2 scripts to work but it seems that things have changed in Tomcat 5. Does anyone know how to do this with tomcat 5. The only thing I can find that comes close to the ApacheConfig class is GeneratorApache2 but from what I can tell this should be called from some other class and not in the server.xml file. Thanks.

Re: tomcat 5.0.16 Replication
Hi Filip. I did some profiling of 40mins of tomcat with and without a 2nd node up. here are the results with -Xrunhprof:cpu=samples,thread=y,file=/u01/portal/java.hprof.txt,depth=10: Those number are cpu=times and not samples since the later one freezes on my systems. So that list shows the time spent in each methods. Major difference the some call to the sun.nio.ch.PollArrayWrapper class. I don't know much about those NIOs packages but 819000 call in 40 mins is a lot. The Socket Interface was called more than twice with 2 hosts than with a single one. Which seams normal. Maybe this can help.

RE: Migrate Apache+Jserv to Tomcat
Howdy, You need to follow the deployment structure explained here: http://jakarta.apache.org/tomcat/tomcat-5.0-doc/appdev/index.html Yoav Shapira Millennium ChemInformatics -Original Message- From: Marco Roda [mailto:[EMAIL PROTECTED] Sent: Thursday, January 08, 2004 11:11 AM To: [EMAIL PROTECTED] Subject: Migrate Apache+Jserv to Tomcat Hello. I am trying to migrate a web application from Apache+Jserv to Tomcat. Under Apache/htdocs I have a folder with the index.html and the applet in JAR format. The servlet zone folder contains the zone.properties, the servlets in JAR format and some other classes. How to deploy to Tomcat? I created a new context and copied to the document root all those files, but only the index.html and applets are visible! It seems that the servlets are not running. What are the right steps?

RE: Microsoft SQL Server validation query
off hand I know selecting the date from sybase, sql server and oracle are all different. one way around it is to use a stored procedure, that way you can have the same stored proc in each RDBMS and the java call is the same. I'm sure others have done it a different way, but that's how I've tackled the problem in the past. peter Derek Mahar [EMAIL PROTECTED] wrote: Thank you to all of you for your quick replies. It seems that the connection pool validation query is not specific to any database server implementation unless the query statement itself is server-specific (that is, it refers to a special server system database, table, or function). I like the idea of querying the server for the date, but I'm not sure that the date function is standard SQL and portable across all server implementations. Does anyone know otherwise?
