Tomcat Configuration

But if I update my classes, I have to do it in both directories. webapps/app1 webapps/app1/Web-inf/classes/mis_clases webapps/app2 webapps/app2/Web-inf/classes/mis_clases webapps/images I think that all classes could be in jakarta-tomcat/classes directory.

Deploying an XSLT filter in Tomcat 4.0
Does anybody know the current level of support for filters in Tomcat 4.0?

RE: Servlet not in webapps directory
Setting your classpath: If you run Tomcat from a DOS console window, before running Tomcat type: set CLASSPATH=%CLASSPATH%;YourServletDirectoy where 'YourServletDirectoy' the full path of the directory were you put your servlets. In that way add YourServletDirectoy to the existing CLASSPATH ( if not existed, this statement will create it). If you run Tomcat through Windows explorer, you should add the line above to tomcat.bat file at %TOMCAT_HOME%\bin directory. You can add it as the first line in this file. Actually, you can add this line also if you run Tomcat from the DOS console window.

Build 3.2.2 errors
Greetings, I'm trying to build Tomcat 3.2.2, and it's not going well. I'm using IBM JDK 2.13. I have successfully installed jaxp-1.1, jsse-1.0.2, ant-1.3, and servletapi-3.2.2. However, when I go to build Tomcat 3.2.2 with either build.sh or build.sh dist, I get several errors. First, jaxp doesn't include parser.jar anymore, so the tomcat script should be updated. Also, jaxp is at 1.1, so I had to artificially rename the directory back to jaxp-1.0.1 so that build.sh would at least copy the first file, if not the second one: prepare: [copy] Could not find file /share/opt/jakarta/jaxp-1.0.1/parser.jar to copy. The real meat of the errors are a series of cannot resolve symbol errors that all appear to be related to SSL. I have set $CLASSPATH and have copied the three jsse jar files into $CLASSPATH and $CLASSPATH/ext hoping they would be found in either location. I've searched the archives of the list and saw one person with this problem, but no solutions. I've also manually registered the security handler in java.security (which only existed under the jre tree -- I copied it to the jdk tree). Here are most of the errors. The rest are very similar. Anyone have any insight?

mysteriously dying connections (Oracle - tomcat)
hi all! problem: database access is managed via a java class that is instantiated and loaded into each clients session. every PL/SQL function and/or SQL statement a client needs is called in a method of this class. first, a connection is opened, the statement is called, all resultsets and statements are closed and finally the connection is closed. (or returned back to the connection pool if one is used) the driver we use is the Oracle jdbc ThinDriver (jdbc driver type 4). after running the system for several days, dead connections (and as we just discovered, tons of open cursors) pile up. eventually the webserver(tomcat) will crash or just hang. in the process, access gets slower and slower, there may be delays of 3 minutes until the webserver (or, perhaps the database, in which case the webserver would be just waiting for the db..) gives a response. after a restart of the webserver or the database or both, the system runns very well again. we tried several connection pools. with these, there were no delays for getting a connection, but the pool threw timeoutExceptions (i.e. made it visible that there are hanging connections) and after a few hundred timeouts the VM crashed with a stack overflow. the connections seem to get killed/kill themselfes randomly no matter which function was called. we log the methods and statements that were called for the connections that die, but there is just no pattern in it. thats why we dont find the root of the problem.. is it the driver ? the database ? the tomcat ? environment: Web Server: Suse Linux 7.2 Apache Webserver /w Tomcat JSP Engine 3.2 /w SSL DB Server: Suse Linux 7.2 Oracle 8i 8.1.7 /w multi-threaded server (MTS) Backup Server: Oracle Shadow server things done: - linux update - apache update - tomcat update - jdbc thin driver update (everywhere the newest version) - tried several connection pools possible changes: - - use OCI drivers instead of thin driver - use J-serv with GNU_jsp instead of tomcat every help is welcome, we're frustrated to no ends. thanks very much in advance!! l.sägesser

After you have that in Tomcat, you just need to JkMount /aName from Apache to complete the job. Make sure you add the context path before it, though, if the context path isn't the root.

Javascript not working
Hi, I have some jsp files, which work under JRun on our intranet, but when I put them on our server on the internet and open them with a browser, I get a javascript error message in the status bar at the bottom of the browser window. Since the jsp files are running on the server in the lan, the reason must have something to do with tomcat, but I have absolutely no idea what I`m doing wrong. Is there a special MIME type for using javascript ? TP

using unsticky sessions
scenario: running 1 apache, 2 tomcats, mod_Jk using load balancing. This all works fine but requests from the client always go to the same tomcat that the original request went to (sticky sessions). I would prefer them to go to tomcats at random. I think this is to do with the cookie/ URL set by tomcat causing the same tomcat to be used. A solution would be to change the session tracking in the tomcat source code and recompiling it, but this may cause problems in future releases. Anyone got any simpler solutions. Thanks in advance
RE: mysteriously dying connections (Oracle - tomcat)
These look like two different issues: 1) Oracle is running out of cursors. a) Make sure you close every ResultSet, Statement and Connection when you're done with them. One trick you can use on Oracle is to log into the database in SQL*Plus as SYS while your application is running, and do, SELECT SQL_TEXT FROM V_$OPEN_CURSOR; to see the SQL for the cursors you have open. b) Try reusing connections and (prepared) statements wherever possible (assuming you use a common Oracle logon for all your accesses). c) Up the number of allowed open cursors, by putting open_cursors = 500 or so in your database's init.ora file. 2) Tomcat is running out of threads.

Do I need to use the AJP13 container for this?
I am running Tomcat 3.2.1 with Apache 1.3.14. My default container is
AJP12(mainly because I haven't tried the AJP13 yet [yeah, i know its in the
docs, just haven't had time to read them to update it to use 13). If I run
the HTML form against this servlet I get this error.
I know usually a java.lang.NullPointerException means something is null
where it should't be (like no params are passsed to the servlet). But the
URL it passes (see below) shows it is passing them.
Any ideas? If you don't think it's tomcat-related, post stating so to
prevent other responses from inappropriately spamming the list and/or e-mail
me back privately if it's not on topic. Thanks!

Re: tomcat, and servlet testing in a multi-user environment
This is a common problem I have had at past employers. What we do now at my company is give everyone Tomcat, it's free right? We have what is called a Deploy Manager or Build Manager. Once a week the DM (or BM) will take the most recent checked-in code from Microsoft Visual Source Safe, move that to the Test server, and then we start Regression testing. We want to make sure everyone's code works with everyone else's. That one server can be started or stopped without bothering everyone else. By having everyone use VSS (or some other Source Control tool) we check in only working code. Everyone daily pulls down the latest code and in a way does their own regression testing on their own machine making sure their code works with everyone elses. The final say is when the BM or DM pulls does their Regression testing. At least once a week, we know everyone's code is working together.

AW: mysteriously dying connections (Oracle - tomcat)
It sounds to me like you're not alway returning the connection to the pool or not closing the connection. But this is hard to say without the source of your java class. If you use a connection pool where you have access to the source code, look if the get and release methods can be intrumented in a way to log each get and release with the hashcode of the connection. Otherwise log each call to get/release in your own code or build a wrapper object around the pool that log this information before calling the pool method. -Ursprüngliche Nachricht- Von: Lukas Sägesser [mailto:[EMAIL PROTECTED]] Gesendet: Donnerstag, 21. Juni 2001 16:38 An: [EMAIL PROTECTED] Betreff: mysteriously dying connections (Oracle - tomcat) hi all! problem: database access is managed via a java class that is instantiated and loaded into each clients session. every PL/SQL function and/or SQL statement a client needs is called in a method of this class. first, a connection is opened, the statement is called, all resultsets and statements are closed and finally the connection is closed. (or returned back to the connection pool if one is used) the driver we use is the Oracle jdbc ThinDriver (jdbc driver type 4). after running the system for several days, dead connections (and as we just discovered, tons of open cursors) pile up. eventually the webserver(tomcat) will crash or just hang. in the process, access gets slower and slower, there may be delays of 3 minutes until the webserver (or, perhaps the database, in which case the webserver would be just waiting for the db..) gives a response. after a restart of the webserver or the database or both, the system runns very well again. we tried several connection pools. with these, there were no delays for getting a connection, but the pool threw timeoutExceptions (i.e. made it visible that there are hanging connections) and after a few hundred timeouts the VM crashed with a stack overflow. the connections seem to get killed/kill themselfes randomly no matter which function was called. we log the methods and statements that were called for the connections that die, but there is just no pattern in it. thats why we dont find the root of the problem.. is it the driver ? the database ? the tomcat ? environment: Web Server: Suse Linux 7.2 Apache Webserver /w Tomcat JSP Engine 3.2 /w SSL DB Server: Suse Linux 7.2 Oracle 8i 8.1.7 /w multi-threaded server (MTS) Backup Server: Oracle Shadow server things done: - linux update - apache update - tomcat update - jdbc thin driver update (everywhere the newest version) - tried several connection pools possible changes: - - use OCI drivers instead of thin driver - use J-serv with GNU_jsp instead of tomcat every help is welcome, we're frustrated to no ends. thanks very much in advance!! l.sägesser

jsp needs updating
Hi, I am at the process of learning JSP, and there are some things I see problematic. If there is a solution for my problem please let me know. First I don't like the fact that there aren't enough standard tag libraries for pervasive operations like database, cookies, html parsing, etcThere are downloadable libraries however, for example the book I am using uses it's own tag libraries and beans which the user has to download. The problem I see with this is that, it is not a standard, which means that if I want to migrate the code it wouldn't work unless I also transfer over the proper classes and tag libraries. Why don't they have a standard out there for JSP rather than using third party classes and tag handlers. Is there a standard java JSP specification tag libraries out there or do we as programmers have to make all the custom tags/ tag handlers for the common programming tags like database,cookies,parsing. etc... In my opinion JSP is a very hard technology to learn and is very misleading because most think of (including myself) JSP as Java's version of PHP or ASP. But in my opinion JSP technology is harder to learn than Java servlets. The reason why I think this is because with all the things you have to learn like creating your own tags which uses XML,creating scriplets( which in my opinion is the easiest part to JSP), creating your own JavaBean, and to top it all off , not having a standard JSP tag library makes it very diffucult as a programmer. It's a combination of XML,ASP/PHP,JavaBeans and Java Servlet. Does anyone share the same view as me or is JSP just about the scriplets and not about any of the other parts I mentioned.
