Re: loading mod_jk.so, undefined symbol: map_name_at
I found this error several times in ths mailing list You should find
the answer...
However this is one for freebsd
I'm not sure where is the error in the makefile because I'm not a shell
expert, but I solve the problem launching by myself apxs.
The location of the apxs is (in my configuration) /usr/local/sbin/ instead
of ${APACHE_HOME}/bin/
After correcting this I launch the Makefile that compile the
mod_jk.so (make all). The script launch :
/usr/local/sbin/apxs -c -I/usr/local/jdk1.1.8/include
-I/usr/local/jdk1.1.8/include/freebsd -DFREEBSD -I/usr/local/apache/include
-I../jk mod_jk.c
As you can see it compiles only the mod_jk.c. The command you have to
launch is:
/usr/local/sbin/apxs -c -I/usr/local/jdk1.1.8/include
-I/usr/local/jdk1.1.8/include/freebsd -DFREEBSD -I/usr/local/apache/include
-I../jk mod_jk.c ../jk/j*.c
If you use a different jdk just yank the apxs command and add ../jk/*.c at
the end as I did.
It works with all the jdk (1.1.8, 1.2 beta native and 1.2 linux)
Hope this help

Trouble with web.xml
Hi All, This is my first post to this list, so hi. I've searched all the documentation I could find to no avail, I've two problems and I'm looking for some guidance. Firstly I'm using Ant and build.xml to set up my web application. This works fine except that it does not place the servlets into the classes directory of the web application it sets up. When I run build, things seem to go fine, it tells me it has compliled the correct number of servlets, but they just disappear... what is going on? I have been getting around that by compling using javac with the destination directory set to my TOMCAT_HOME/webapps/myapp/WEB_INF/classes directory. This all works, my HelloWorld.class servlet runs like a beauty :) My next problem is that I cannot get my servlets to recognize web.xml. I place this file in WEB-INF directory for the web app, but any init-param I try and use comes back as null. I am sure I have the syntax of the web.xml file correct. This even happens when I place my servlets in TOMCAT_HOME/webapps/examples/WEB-INF/classes directory and edit the pre-existing web.xml file to include my init-params. Thanks is advance for any advice. Cheers Matt Campbell - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
Question
Thank you in advance for any help you can provide. I am a java enterprise developer and develop generally on my standalone notebook where I use Jigsaw, JavaWebServer and Apache/Tomcat. All work fine. My notebook used Windows 98 and my application currently under development uses MS Access. When I moved all three web servers to my NT Server machine, installed and started. Only the JavaWebServer2.0 works as expected. Both Jigsaw and Apache/tomcat fail. Here is what happens: My application uses servlets which extracts information from an Access database and merges with internally generated HTML documents and sent to the client over the internet (network at this point in time). The moment the program attempts to access the database I get a Doctor Watson error which says error Java.exe 'access violation' along with some additional cryptic information. I do not get this error with JavaWebServer nor do I get it in any of the three web servers when running in my notebook (windows98). If I reverse the process and execute the application from the NT Server using my notebook as the webserver (apache/tomcat), all works perfectly. It seems to be the NT Server that is causing me problems but can't pinpoint it. Has anyone encountered this problem and what is a possible solution?

RE: Trouble with web.xml
Hello, welcome. I'm not sure I understand the first question in the context of tomcat. However ant usually puts things in projectroot/build/classes/x/x/x where project root is the directory where your src, lib, etc files are. It also usually copies all the sources to build/src. As for your webapp. If you want the WEB-INF/web.xml file to be heeded you must have your OWN webapp (not part of the examples). To do this create your own subdir usually /opt/tomcat/webapps/mywebapnamehere and put your WEB-INF there /opt/tomcat/webapps/mywebapnamehere/WEB-INF. You will need to add entries to server.xml (see how /examples) is setup. I generally put my webaps under their own tomcat subdir for organizational purpose (I don't want to intermingle with examples)... if you want to edit the examples to include yours then you're likely running into the init-param format being not quite so obvious... EACH param-name,param-value pair must be surrounded by an init-param /init-param not all under one. This is a very common problem. -Andy -Original Message- From: Matt Campbell To: [EMAIL PROTECTED] Sent: 1/28/01 9:56 AM Subject: Trouble with web.xml Hi All, This is my first post to this list, so hi.

a few strange problems
I recently installed Tomcat 3.2.1 on a RedHat 6.2 Linux System and have come across some strange issues. I am using it solely for the jsp functionality not for servlets. I am running it in conjunction with Apache 1.3.12(to serve static content, images etc.) Whenever I do an include, from a .jsp file, that passes a param value with 'nbsp;' in the value string I get some really strange exceptions, the first exception is a FileNotFoundException, all of the included files are referred to relatively i.e. "../header.jsp" and do exist, if I remove the ".." I can get rid of the FileNotFoundException. Ok, but now I get: Internal Servlet Error: javax.servlet.ServletException; Root Cause: java.lang.IllegalArgumentException. (please let me know if you need more info than that as the full errors were much longer etc.) Finally, to fix this, I remove the 'nbsp;' from the param line in the include statement below. jsp:include page="/header_out.jsp" flush="true" jsp:param name="cur_page" value="Learnnbsp;More" / /jsp:include The next issue I am having is pretty simple, I have a directory my_admin which when accessing *.jsp I get a "404 File Not Found", but if I change the name to myadmin(note: no underscore "_") everything is peachy. HTML files work fine in both situations. Are these bugs(known?) or do I possibly have some problems in my configuration? If it is a problem in my configuration, any suggestions?

JDBCRealm - can't make it work
I am trying to setup some webpages hosted using Tomcat and I am facingproblems to access the MySQL databse from the webpages.I have setup Tomcat-3.2.1(binary) and Apache_1.3.14 with MySQL-3.23.31 underRedHatLinux 6.2. Tomcat, Apache and MySQL are basically working fine whereasjdk1.3 is installed under /usr/java. I have to setup login authenticationfrom the webpages accessing data from MySQL (name of database is test). Ithink Tomcat supports JDBC and not ODBC and therefore I am trying to useMM.MySQL for JDBC connectivity to MySQL. I am having lack of understandinghow to properly setup MM.MySQL in conjunction with Tomcat.As indicated in Tomcat/MM.MySQL documentation, I have tried as follows:1. Modified $TOMCAT_HOME/conf/server.xml to add following lines: RequestInterceptor className="org.apache.tomcat.request.JDBCRealm" debug="99" driverName="org.gjt.mm.mysql.Driver" connectionURL="jdbc:mysql://localhost/test''" /2. Unpacked mm.mysql.jdbc-1.2c.tar.gz under /opt3. Have set up CLASSPATH as /opt/mm.mysql.jdbc-1.2c4. Copied both mysql_comp.jar or mysql_uncomp.jar (one at a time) to$TOMCAT_HOME/libWhen I am trying to access my webpages under Tomcat, I am getting an errormessage on the linux console as: java.sql.SQLException: No suitable driverFurther when I am trying to access MySQL through my Tomcat webpages ortrying to stop Tomcat, I am also getting error message as:java.lang.NullPointerException Do I need JDBCRealm.class file? If yes, how to get and where to place? I have file under $TOMCAT_HOME/src/org/apache/tomcat/request/JDBCRealm.java but if I try to compile it, I am getting lots of errors.In a separate environment, I have used NT4.0, JavaWebserver, MySQL and ODBCdriver. Every thing is working over there including database access from theWebPages.In the Linux setup in question, I have also installed ODBC driver and driver manager(libiodbc-2.50.3 and MyODBC-2.50.36) for MySQL and the sample odbctestprogram is able to access data from MySQL. However MySQL can not be accessedfrom the WebPages and I believe Tomcat need to configured to work with theODBC driver if at all it can support the ODBC. Tomcat documentation isreferring the use of a JDBC driver MM.MySQL which is also installedhere(mm.mysql.jdbc-1.2c) under Linux. But the documentations are not thatclear to me and I am unable to understand and complete the associatedconfiguration.Can somebody help?Thanks a million in advance.Dipankar

Re: Trouble with web.xml P.S.
I was wondering about that. I just finished reading the Servlet Specification and they made no mention of Init Params under the servlet element. And I wondered how they interacted with Init Params at the context level. You're saying that the servlet init params completely over shadow the context init params? fern On Sun, 28 Jan 2001, William Brogden wrote: Matt Campbell wrote: Hi All, this is an addition to my last post, a bit more info in case its any use.

If you address it as snoop - the alias that the web.xml sets up with: servlet servlet-name snoop /servlet-name servlet-class SnoopServlet /servlet-class init-param param-namefoo/param-name param-valuebar/param-value /init-param /servlet then you will get the init params - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
Re: Problem in starting tomcat
Andrew Tan wrote: I installed tomcat on Windows98 When I double click on "startup.bat" it says opening in another window (the window comes on and then disappears). And it seems that tomcat has not started. Do you have similar experience? and is there a solution? Regards, Andrew 1) Open an MSDOS Prompt window 2) Right click the upper left corner - select properties 3) on the memory tab of the properties dialog, change the initial environment to 3072 or 4096. The reason being that startup.bat adds LOTS of strings to the environment, too much for the normal win98 setting. 4) change directory to tomcat\bin and execute startup.bat if it doesn't work, at least you will be able to see error msg. -- WBB - [EMAIL PROTECTED] Java Cert mock exams http://www.lanw.com/java/javacert/ Author of Java Developer's Guide to Servlets and JSP ISBN 0-7821-2809-2 - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
Tomcat and SSL
I followed the instructions to the letter and I've tried it on two different platforms, so I'm just flat out MISSING something. I rebuilt Tomcat with SSL with no problems, modified my server.xml for SSL and it started with no errors, but when I go to connect to the SSL port from a browser I get a message on Netscape of "Netscape and this server cannot communicate securely because they have no common encryption algorithm(s)." and on IE it just gives the generic "Can't display this page" garbage. Has anyone seen (and hopefully solved) this problem??? Thanks.

Ctx( ): IOException in: R( + /images/dm2.gif + null) socket write error (code=10053)
Hi,
I have this problem loading hundreds of images in
my applet from the server (Tomcat 3.2.1) with ~ following code:
// in applet.init()...
for (int i=0; i1000; i++) {
URL location =
getClass().getResource ("/images/image"+i+".gif");
Image img = this.getImage
(location);
if (img != null)
images.addElement (img);
}
// ...
After loading ~50-60 images this way, I start to get
Ctx( ): IOException in: R( +
/images/imageX.gif + null) socket write error (code=10053)
for all resources including classes of applet being loaded by class
loader.
PLEASE HELP!!!
Cheers,
Maxim
RE: how to handle a user clicking very fast repeatedly on a web page
A long time ago I had this problem, specifically with submit buttons for
forms. But The technique I used was rather straight forward:
in your web page have this javascript:
function disableMe(obj) {
obj.disabled=true;
}
then your HTML buttons and links can have this as an onCLick handler:
eg:
input type="submit" name="submit" value="Click Me Many Many Times I Dare
you!!" onClick="disableMe(this)"
What this does is renders the link or button unclickable. If you have a
submit button problem, and are worried, this is a very quick fix.
Unfortunately this is only half of the solution since this way only works on
IE:
but there is another solution for netscape!!
place all the objects you want to disable into netscape layers and then
invisify them onClick =) its a dirty trick but it works.
Have fun =)
