Re: Tomcat j2sdk and image
Hi, do you have a graphics environment when running under Solaris? If not then that would be my guess to a reason why it's not working, since you have a graphics environment when running under W2K. Try adding -Djava.awt.headless=true to your commandline when starting tomcat. If this doesn't do the trick, you need the graphics environment to generate your images.

Re: How get www.site.com homepage requests to forward to Tomcat without a redirect?
Hi, try removing the [R] from your RewriteRule. If you read up on the mod_rewrite docs, you should see that the [R] flag is causing the redirect. Trond PAlvin wrote: I'm currently using Tomcat 4. When someone goes to my site, say, www.site.com, I'd like it run a servlet for the home page instead of a static page (my entire site is dynamic). I configured the connector to send all *.htm files to Tomcat and I created a re-write rule in the Apache configuration file like this: RewriteEngine on RewriteRule ^/$ /home.htm [R] This works great, EXCEPT, that the browser is sent a redirect and I heard that is bad for search engines. I could send *all* http requests to tomcat, BUT, obviously, I DON'T want Tomcat serving up images. So, is there any way to configure Apache and/or Tomcat to make: www.site.com ---run-- www.site.com/home.htm without a redirect? How do I get www.site.com requests to go to Tomcat???

Re: Tomcat 5 + Apache SOAP?
I also would recommend Axis, but if you put the jar files in common/lib you will not be able to reload your app. At least that happened to me with axis 1.1 under 5.0.28... That also breaks the rule that the app should be as self-contained as possible to make it as portable as possible. Trond Mark Leone wrote: Apache SOAP is the original apache SOAP implementation. I recommend you check out apache Axis, its successor. I have Axis 1.2 (formerly ran 1.1) running in Tomcat 5.5.8, and I had it running in Tomcat 4.x for over a year. Just make sure that the jar files that Axis needs are in the common/lib directory (if Tomcat needs them also). Not sure if HttpServlet is in that catagory, but worth a try.

Re: TC 5.5 and commons-dbcp
Hi Robert, the JNDI resource configuration has changed in 5.5. Check out the docs for an example: http://jakarta.apache.org/tomcat/tomcat-5.5-doc/jndi-datasource-examples-howto.html. Also Tomcat 5.5 has changed the commons-dbcp-x.x.x.jar to naming-factory-dbcp.jar. And the org.apache.commons.dbcp.BasicDataSource is now moved to org.apache.tomcat.dbcp.dbcp.BasicDataSource. Trond Robert Bateman wrote: I'm in the process of moving an application that is in production today on a TC 4.1.30 deployment over to 5.5. So far, everything has moved without too much trouble. That is, until I get to the use of commons-dbcp in the code. The code uses BasicDataSource to interface to commons-dbcp. Under 4.1.30 (and I believe 5.0 as well...) I can do: Context ctx = new InitialContext(); BasicDataSource ds = (BasicDataSource)ctx.lookup(jndi string); And I would get a data source. Under 5.5.7 and 5.5.9, ctx.lookup() throws an Exception.

Re: Thanks Trond
Hi, at office I am using tomcat 5.0.25. In that server my jsp's are running but when I try to run servlet in IE the browser tell me download the war file instead of executing it. How do you deploy your war file? I'm guessing that you have not used the manager since you could not login? The only way I can make sense of this, is if you have copied the war file into $CATALINA_HOME/webapps/ROOT/ and try to access it from your browser by entering http://localhost:8080/myapp.war. If this is the case then you should copy the file into $CATALINA_HOME/webapps instead and tomcat will automatically expand your war file into a directory named after your war file, and you should be able to access your jsp files by entering http://localhost:8080/myapp/myfile.jsp If you have deployed your war file correctly I don't know what is causing this behaviour. - Trond - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

If you are running tomcat please try it and let me know if tomcat crashes and with which version. After looking for hours I found a filter that catches all the incoming requests. Each request is put in a queue and the first and last request is let through, the rest is thrown away. This seems to work. Has anybody else got this problem?

Re: Very Straneg problem with MySQL-Connector
Hi,
your ploblem is most likely debian related. In debian mysql has a config
parameter skip-networking which denies tcp connections to mysql. Make
sure this setting is not set, and that you grant your user access from
127.0.0.1 not localhost because when using localhost mysql expects the
user to connect via a unix socket, not a tcp socket.
Good luck

I am Using : Tomcat 5.0.28
MySQL-Connector version is : mysql-connector-java-3.0.15-ga-bin.jar
JDK Version : 1_5_0_01. Servlet-Examples and JSP works fine! So I don't think the problem come from JDK.
MySQL version : MySQL-SERVER-4.1.9-2 : All is working under console mode !
Here's My Servlet TESt1.java:
Code:

String password = password;
try{

Connection connection = DriverManager.getConnection(url,user,password);
out.println(br Database connection : OK!);
}
catch (ClassNotFoundException e)

Theses codes works very well under windows, but under linux system here what
I've got :
DRIVERS JDBC : OK!
ERROR MESSAGE
Message: Invalid authorization specification message from server: Access denied for user 'root'@'monkinetwork' (using password: YES)
SQLState: 28000
ErrorCode: 1045
Well, the web.xml file is well configured.
Anyway : I already tried with class: org.gjt.mm.mysql.driver, but I have the same message error !
By the way, it's very strange that I can play with MySQL under the terminal but not throught tomcat.
Any suggestions please , because it's giving me a very hard time ! ?

Cookies in Tomcat 5.5.7
Hi all!
I'm making a filter that checks that my cookies are set, and sets them
if they are missing.
Code for setting cookie:
String path = request.getContextPath();
cookie = new Cookie(name, value);
cookie.setPath(path);
logger.debug(Setting cookie: + cookie.getName() + , +
cookie.getPath());
response.addCookie(cookie);
Code for checking cookies:
String path = request.getContextPath();
for (Cookie c : cookies) {
String cName = c.getName();
String cPath = c.getPath();
logger.debug(Checking: + cName + , + cPath);
}
When setting the cookie the Cookie.getPath() method returns the path I
have set. But when checking cookies all calls to Cookie.getPath()
returns null regardless of what path I have set. When viewing the
cookies in Firefox the path is the same as when I created the cookie.
Is this a bug?
Has anyone experienced similar behaviour?

Re: commons-logging logger instances - how to initialize in replicated session objects
Hi,
I'm maybe stepping out of my territory here, but I think that static
members are not serialized/deserialized. To re-initialize your static
logger maybe you should try to implement the
readObject(java.io.ObjectInputStream in) method from the
java.io.Serializable interface something like this:
readObject(...) {
super.readObject(...);
log = LogFactory.getLog(...);
}
Hope this is of some help

Re: Tomcat 5 - Datasource Connection Pooling
Hi! 1)My problem is my working directory is different. I use ant to create war file and then i manually stop the server - delete existing war file / existing directory (This is due to some Win TomCat problem .??..). Then i deploy it using TomCat Manager. It automatically creates META-INF file for me, i do not have META-INF inside my working directory. So where i can put my context.xml ? You have already answered this yourself, META-INF/ directory of your war file. The only way to avoid the META-INF directory is to not use a war file, as a war file simply is a jar file, and the META-INF is part of the jar file specification. 2) What shall i put inside context.xml and what shall i put inside server.xml / web/xml ? The example pages: http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jndi-datasource-examples-howto.html tells you exactly what to put in each file. You just have to read them one more time and keep focused. I'll give you some hints as well: - Leave server.xml the way it was before you started tampering with it. - Copy CATALINA_HOME/conf/enginename/servername/yourapp.xml, to your context.xml file, and add your resource specification inside the context as in the examples. Then include context.xml in your war file in the META-INF dir. Your app must be running for the yourapp.xml file to exist as it is deleted when you undeploy your app. - In web.xml you need to add a resource-ref as you can see from the examples Good luck Trond - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Hi Michael -jvm JVM name use a specific Java Virtual Machine. Available JVMs: 'null' It says null because jsvc cannot find your jvm.cfg file.

So I made a symlink to it in JAVA_HOME/jre/lib and then running jsvc -help on my box is looking like this: -jvm JVM name use a specific Java Virtual Machine. Available JVMs: 'client' 'server' Now you should be able to start jsvc with the -jvm server option set.

Session restart replication when using jsvc
Hi all! I recently switched from using Tomcat 5.0.28/jk2/Apache2 to running tomcat standalone using jsvc. This works great for me except for one thing; Sessions are not replicated when I restart tomcat. To stop Tomcat I'm using 'kill -9 `cat /var/run/jsvc.pid`'.

Migrating from Apache2/JK2 to Tomcat standalone
Hi all! I'm migrating from Apache2/JK2/Tomcat 5.0.28 to Tomcat standalone (don't need php anymore), and have some questions regarding the matter. 1) Since Tomcat now will be serving all the static content as well, will it require more threads than when only serving dynamic content? 2) In Apache I'm using mod_rewrite to rewrite requests to mydomain.com/ to mydomain.com/myapp. I've implemented this behaviour by using response.sendRedirect in a scriptlet in the index.jsp of my ROOT app. Is this the preferred way of doing this? 3) In Apache I'm using some aliases to serve images stored outside my appbase from insisde my webapp (Alias /myapp/alias /path/outside/appbase). I've implemented this by creating context xml files for all my aliases with appBase=/path/outside/appbase path=/myapp/alias. Again, is this the preferred way of doing this? 4) I've compiled jsvc and adapted the Tomcat5.sh to start the server. If I do Tomcat5.sh stop ; Tomcat5.sh start to do a restart of the server my machine hangs. If I allow a pause between stop and start then the server starts with no problem. Is this a known issue?

Re: Migrating from Apache2/JK2 to Tomcat standalone
Thanks for your replies Allistair :) 2) In Apache I'm using mod_rewrite to rewrite requests to mydomain.com/ to mydomain.com/myapp. I've implemented this behaviour by using response.sendRedirect in a scriptlet in the index.jsp of my ROOT app. Is this the preferred way of doing this? Depends on what you want. If you want mydomain.com/ to be your web application, that's fine, your webapp needs to be the root web application. If you want mydomain.com/mywebapp that's OK too. You don't need a redirect of any kind. This functionality is setup using Context element configuration more of which is in the online Tomcat documentation :) All our customers have links to mydomain.com/myapp/mypages, so it's easier for me to keep this layout, than having my customers update their links. 3) In Apache I'm using some aliases to serve images stored outside my appbase from insisde my webapp (Alias /myapp/alias /path/outside/appbase). I've implemented this by creating context xml files for all my aliases with appBase=/path/outside/appbase path=/myapp/alias. Again, is this the preferred way of doing this?

I don't *have* to do it, it's just that my connection to the server is so slow so I wanted to save time when uploading new versions ;) Trond - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Axis and Tomcat
Hi, Perhaps for development you can use an unpacked WAR, set reloadable=true, and only upload the relevant classes/jars as needed, instead of the whole WAR... I have this setup in dev environment, but I make weekly releases to the production server, sometimes twice a week depending on how many bugs I introduce ;) Those uploads are the ones taking time. For development I am using the setup you suggested. Thanks again for all help. Trond - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
[OT] Which webframework to use?
Hi all! Obviously I'm way off topic here, but I'm posting this anyway. I started developing JSP/Servlets using Tomcat 6 months ago. At the time I started developing my app I wasn't much aware of MVC and frameworks to help me with that, so I have developed everything from scratch. Lately I have been reading up on Spring, WebWork, Struts and JSF. It seems to me that the question is to Struts or not to Struts. People using Struts are convinced that they have the right solution, but some of them are scared that JSF is going to take over. And Spring seems to go on about how easy it is to use and also mix with other frameworks. My webapp is somewhat close to the MVC pattern, not bad for not knowing about it when design started :), and I think that it should be quite easy for me to implement one of these frameworks. In my understanding the biggest competitors are Struts and JSF, and in the 2.x release of Struts they will rely on JSF as supporting technology so one of these seems to be a good choice. Any good tips on the matter would be greatly appreciated. Trond - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
JDBC transactions using MySQL / DBCP in Tomcat 5.0.28
Hi all!
In my webapp I do two db inserts into two different tables. If the
second one fails I want to rollback the first one. My code is something
like the following:
Connection con = gotten from jndi DataSource
DBBean db = new DBBean(con);
try {
con.setAutoCommit(false);
Object o = db.getSomething();
Object o2 = db.getSomethingElse();
db.doInsert1(params);
db.doInsert2(params);
con.commit();
} catch (SQLException sqle) {
con.rollback();
throw sqle;
} finally {
if (con != null) {
con.close();
}
}
I thought that this should do the trick, but if the second insert fails
the data inserted in the first insert are still there. I am using MySQL
4.0.21-7 with InnoDB and have tested that I can use transactions with
the MySQL client.
Anyone got any tips?
Regards
Trond

Re: JSP fragments file extension and the jasper2 ant task
Hey Jim, thanks for the tip. This works when the jspf files are compiled in tomcat, but the jasper2 ant task does nothing with them...

JSP fragments file extension and the jasper2 ant task
Hi all! The J2EE 1.4 tutorial says: The recommended file extension for the source file of a JSP page is |.jsp|. The page can be composed of a top file that includes other files that contain either a complete JSP page or a fragment of a JSP page. The recommended extension for the source file of a fragment of a JSP page is |.jspf|. My project is growing and it would be nice for me to use this difference in extension to easier separate top files from fragment files. I precompile my jsp files using the tomcat deployer, but it won't compile my fragment files if i give them the .jspf extension, and change my jsp:include to reflect this change. Is there a way to make the jasper2 task also include these files? I haven't found any docs on the jasper2 task anywhere. A hint to find these would be appreciated.

Apache / Tomcat restart
Hello all! I'm running a webapp with apache 2, tomcat 5 and jk2 under debian. The system is running fine for about a week or so. Then some strange small things start to happen. The webapp loads new pages put doesn't show them in a browser, all GET requests are ok, but POST requests are not responding, and other things like that. When apache / tomcat is restarted everything is back to normal. I wonder if other people are experiencing similar things? How often do you _need_ to restart your systems? There is no problem for me to restart the system with a cron job at night, but if you guys don't have to restart why should I? I think that my tomcat / jk2 config is proper, but I have no experience in configuring apache 2 so this is pretty much out of the box configured.

Re: Apache / Tomcat restart
Hi Shapira, the reason for running apache / jk2 is that we are running other things on the same server using php. Haven't tried to make php run inside tomcat, never even checked to see if it is possible. The php stuff existed before we started using tomcat so the natural approach for us was to expand our existing solution to also support running servlets / jsp. However we are in the process of porting our old php stuff to servlets / jsp, so in the near future we should be able to use tomcat standalone. I'm a junior (2yrs. exp.) and curious about hints / tips when you talk about good design and support / maintenance practices. Pointers to good docs on these topics or som pointers from you or others that are more experienced than myself would be much appreciated.

Active connections in db pool
Is there a way of finding out how many commections which are currently active when using a db connection pool? I got this error message in my logs: Cannot get a connection, pool exhausted. When I increased the number of mxActive the error message of course disappeared. I tripled the number of connections just to make sure that it will not happen again for some while, but I would like to check the value from time to time so I can increase it yet again if that would be necessary or decrease it if I really needed just oldMax + 10.

Stability problems using Apache / Tomcat / jk2
System:
Debian testing i386
jdk1.5.0
Tomcat 5.0.28 - CATALINA_OPTS -ms64m -mx128m
Apache 2.0.52-1
libapache-mod-jk2 2.0.4-3
MySQL 4.0.21-7
mysql-connector-java-3.0.15-ga
Tomcat is running a service called Tomcat-Apache, an engine called
Apache with
a host called localhost. localhost has the /admin and /manager webapps

connection pool to MySQL.

Here are my problems
1. Strange log message
This message shows up frequently in error.log:
[Tue Oct 19 17:14:40 2004] [error] ajp13.service() ajpGetReply
recoverable error 3
[Tue Oct 19 17:14:40 2004] [error] ajp13.service() ajpGetReply

ajp13:localhost:8009 1 0
[Tue Oct 19 17:14:40 2004] [error] mod_jk2.handler() Error connecting to
tomcat 3, status 200
2. Serious stability problem
Sometimes tomcat stops and gives a 500 error. This seems to happen at
times
when load is high, but happens every once in a while when load is low as
well.
A restart of Tomcat does the work. This results in having to restart
tomcat at
least 2-3 times a day.
This is what show up in the logs
