Re: Changing the JVM

If your system is still accessing the old /etc/profile, you may need to restart it. Another possibility is that there are still some variables pointing to the old jdk from another script. It may be a terrible idea, but I've been setting my variables to point to /usr/local/java/JDK. JDK is a link to my current version of the j2sdk. This makes changing very easy as I just have to delete the old link and create a new one.

Read of HTTP Request POST parameters failed
I've got an intermittent error that's giving me a real headache.

Re: problem with hyphen in hostname
Here's a little more info... The problem is that the hyphenated hostname being given to the browser (www.first-last.com) is being changed by the servlet and the hyphen is being removed (www.firstlast.com). (Of course that's not a real domain name but it illustrates what's happening more clearly.) Both domains are legitimate for this server. Both are recognized by Apache. The actual hostname (from /etc/hosts) is something completely different. All of this is taking place in the servlet. I haven't tested this in a jsp page. When I give response.sendRedirect() a relative url, I notice that the hostname is changing in the browser's location bar. Absolute urls are not a problem. In testing, I noticed that request.getRequestURL() and request.getServerName() also return the hostname without the hyphen. Further testing found that request.getHeader(host) returned the correctly hyphenated hostname given when the servlet was called by the browser. The workaround I'm using is to build an absolute url using the hostname from the header and redirect to that url instead of the relative url I'd been using. Is this expected behavior? It would seem to me that the hostname given in the user's browser's location bar should be being maintained throughout the session unless changed by a redirection. (Which of course is what's happening.) I don't understand why the redirection and the two request methods are dropping the hyphen. Am I doing something wrong? Thanks Cindy At 11:26 PM 3/11/03 -0800, Bill Barker wrote: I just tested this, and it works for me. My first guess would be that the Host tag is setup wrong.

RE: Custom Tag / JavaBean question
This is great!
It's exactly the information I needed.
Thanks!
At 01:57 PM 10/15/02 -0400, Tim Moore wrote:
The problem lies in the fact that you've overloaded the setter method
for accessList. According to the JavaBeans spec, you can't do that;
only one setter per property name is supported. So, first of all,
you'll need to give the attributes two different names and make them
both optional.
For example:
public void setAccessList(Collection accessList) {
this.accessList = accessList;
}
public void setAccessListName(String accessListName) {...}
But what's more, because of the way tag pooling works, you probably
don't want to resolve the name in the setter method as you do below (see
http://jakarta.apache.org/taglibs/guidelines.html) so you should have an
accessListName field too, and write setAccessListName just like:
public void setAccessListName(String accessListName) {
this.accessListName = accessListName;
}
then, in doStartTag:
Collection accessList = this.accessList;
if (accessList == null) {
accessList = (Collection) pageContext.findAttribute(accessListName);
}
Kind of a pain, but that's the only way to be fully compliant with the
spec.

Iteration tag question
Not directly a Tomcat question, but I hope not too far off topic. Let's say I have a collection of objects that I want to iterate through and display on a JSP page with a custom tag. The body content of the tag on the page formats the output as rows and elements of a table. Now, let's say I want to skip a few of the objects in the middle of the collection. How can I skip those objects without having the tag output the empty html tags from the page? I've tried all of the doAfterBody() return values I can think of with no success. (They either process the empty body content or stop processing altogether.) I assume that I'm going to have to play around with the BodyContent or PageContext, but I can't find any examples that show how to do this and it's not intuitive to me. Any suggestions or examples would be greatly appreciated. Cindy -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

be the result of something stupid I might be doing in my servlet.

dynamic page building question
I'd like to make a page that will allow users to dynamically add and modify page elements by clicking on form buttons on the page. I'd like these changes to automatically appear on the page. The simplest way to do this would be to use javascript and document.createElement() to apply these changes using the DOM. Unfortunately, this doesn't work with all browsers.

Let me first put in a caveat that I ain't no expert and while I *think* this is true, it may not be. ;-) The Context tag of your application should point to some real directory where your application resides. My application is called Applications. (real original, huh?) Here is my Context tag... Context path=/applications docBase=applications/web debug=99 reloadable=true This is pointing to a directory at $CATALINA_HOME/webapps/application/web which is where all of my jsps live. When I enter the url http://localhost:8080/applications/ this is where it goes. Context path=/DBTest docBase=DBTest debug=5 reloadable=true crossContext=true So the Context tag you have is pointing to the directory $CATALINA_HOME/webapps/DBTest. If that doesn't exist it would explain at least some of your errors. It sounds like your application lives in $CATALINA_HOME/webapps/test so you could try something like this in your server.xml... Context path=/DBTest docBase=test debug=5 reloadable=true crossContext=true The jdbc/Support thing is a mistake on my part. That should read jdbc/devdb. Support is the real name of my MySQL database. I was calling it devdb because I thought it would make more sense and obviously I've just muddied the waters more than they were. Sorry about that. The WEB-INF directory lives under the application path and web.xml lives inside of WEB-INF. So on my system that would be $CATALINA_HOME/webapps/applications/WEB-INF/web.xml. Again, if your context path doesn't exist, those woun't be found either. I hope this is correct and that it helps clarify things for you.

RE: plain MySQL DataSource in Tomcat (i know, damn topic)
Hi Clay, It's a small net. I hope you are well!! I haven't tried using Struts yet, but I've been thinking about checking it out. I did try the JNDI/DBCP method described at the URL you posted and it does work and it seemed to be pooling correctly. However, the connection times out after a while which is a real pain. I haven't had time to figure out what's going on with that and work out fix for it yet. Also, DBCP seems a little immature to me at this point, so I'll probably wait a little while and try that again. I also tried the JNDI/Tyrex setup and was able to get a connection, but I couldn't tell if it was pooling properly and I ran into some bugs with Tyrex so I abandoned that approach. I've been using DbConnectionBroker using a set up similar to that described in Bergsten's Java Server Pages book. The connection is stable and the pooling is working well. I don't know how much of a load this will handle, but for the time being it's allowing me to concentrate on other things. I'd much rather be using JNDI, but I think that this is the most stable approach going right now. I hope this is at least a little bit helpful.

Re: Connection Pooling Solution
fillup, At 01:28 PM 5/30/02 -0700, Phillip Morelock wrote: javax.sql.DataSource itself is not returning Connections. DataSource is an interface -- what this means in practice is that some random class (in this case, BasicDataSource) is implementing that interface. You're actually asking that class for a Connection, and you know that you can call any method on it that is defined in javax.sql.DataSource because it implements that interface. So while your code might hypothetically look like (partially pseudo-code): BasicDataSource bds = Somewhere.getDataSourceObject(); Connection conn = bds.getConnection() ; it's far more flexible to do this: DataSource ds = Somewhere.getDataSourceObject(); Connection conn = ds.getConnection(); If you get another database connection pool (say, from MS or Oracle or something) and you want to change the actual class for the DataSource (say, now it's MSSQLServerDataSource or whatever) -- as long as that next class still implements the javax.sql.DataSource interface, you can still work with it without changing any of your code, just the config file that tells Tomcat which DataSource class to use. So all you would do if you have to change databases or driver classes, is change web.xml or server.xml or wherever you have the driver / data source class configured, and all your code can remain using DataSource as the type of the object, no changes from BasicDataSource to MSSQLServerDataSource all over the place. Is this clear? Yes, much more so. Thanks! I was misunderstanding the whole relationship. I spent some time going over the source for BasicDataSource and I think I'm much clearer on the whole thing.

the ups and downs of JNDI connection pooling
After reading every message I could find in the archives (and marveling at the blood, sweat, and tears shed over this subject) I believe that I've finally got JNDI connection pooling working with the Tyrex software!!! My joy was boundless until I started having problems with Tyrex itself. (For example, NullPointerExceptions when Connection.setAutoCommit() is called.) The development archives seem to confirm this and other problems and talk about DBCP as the pooling software of the future. I found the DBCP pages (at http://jakarta.apache.org/commons/index.html), but it appears to be a log ways from being ready for a production environment. Are there are reliable ways to do connection pooling with JNDI or should I just go back to DbConnectionBroker and be happy with that?

It's ignoring anything requested from anywhere else. Likewise, Apache's access_log shows the request for the jsp page (which makes sense since it was called on port 80), but nothing else. All this is as I would expect. However, mod_jk.log is showing an entry for every single request that comes to the server, including Nimda probes!! I'm willing to ignore it if everything else is ok, but I'm concerned that I've got some sort of configuration error somewhere that's going to bite me later on. Thanks again!

java.util.zip.ZipException: Permission denied
Can anyone tell me why I would be getting a java.util.zip.ZipException: Permission denied error in catalina.out? (The entire error is at the bottom of this e-mail.) This seems to be the last things that happens when tomcat starts. I'm also getting some similar errors in my application's log file that seem to relate to the jar files that contain the classes for the taglibs. However, right after those error messages, there are messages suggesting that the jars have been successully read. These messages have been appearing for some time while the exception in catalina.out is new so there may be no relationship between them. Any thoughts would be greatly appreciated.

I've never tried Tomcat with the Blackdown JDK, so there could also be a bug in the way Blackdown implements JAR file reading (which uses ZipFile classes inside). Could you try this with some other JDK to see if the problem goes away? Craig That was my first thought. I recently started using jdk1.3.1_02 from Sun and I was thinking that this change might have been the cause. I changed back to the Blackdown jdk and the results are identical. By the way, these errors don't seem to be interfering with the functionaing of the application I'm working on, if that's of any interest.

problem with WebAppConnection at boot time
I've been reading through the archives and I've seen a lot of questions about using mod_webapp. In general, mod_webapp seems to be working pretty well for me. My problem is that it doesn't seem to be able to make a connection when httpd is started at boot time. I'm using RedHat 7.0 and I've written init.d scripts for both Tomcat 4.0.1 and Apache 1.3.19 (both installed manually rather than from RPMs). Tomcat starts before Apache (Tomcat is S80 and Apache is S89). Both seem to be starting correctly and both can be accessed directly from their respective ports. The problem is that the Apache error_log has a string of entries like this... [Thu Feb 7 10:20:24 2002] [error] Connection conn cannot connect [Thu Feb 7 10:20:24 2002] [error] Cannot open connection conn ... and when I try to access a jsp from one of the contexts defined by WebAppDeploy in Apache, I get a WebApp: Error 404 (File: wa_request.c Line: 198) Web-application not yet deployed page, and an entry in the log like this one... [Thu Feb 7 10:20:42 2002] [error] Web-application not yet deployed Interestingly, viewing the source of this error page gives me the html that should be produced by the jsp application I was trying to access!! Restarting my web server seems to correct this problem. The connection is made and my jsp files are accessible as I would expect. This indicates to me that my configuration is essentially correct, but something is preventing the connection from being made at boot time. Could Tomcat not be fully loaded when Apache is trying to start? Should I put more space between the init.d scripts? Are there other daemons that need to be started in order for webapp to deploy? Any suggestions would be greatly appreciated. Cindy By the way, mod_webapp is version 1.0.1 built from source with -DEAPI. -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]
RE: problem with WebAppConnection at boot time
John, Thanks for the info! I wrote a new script loading both Tomcat and Apache with sleep 10 in between and it does work. The other behaviors you describe certainly are strange. I haven't seen them yet, but I've only just upgraded from Tomcat 3.3 a couple of days ago. How do you feel about mod_webapp? Is it stable enough to be used in a production environment? Thanks again! Cindy At 07:47 PM 2/7/02 -, John Wadkin wrote: The error Web-application not yet deployed is a weird and wacky one. It seems to come and go. If you restart rather than stop and start Apache at the command line, it seems to manifest itself. It sometimes disappears of its own accord with no intervention from me! As I understand it, it's caused by Apache starting before TomCat has fully loaded. But this wouldn't explain its weird behaviour. I think it's a known bug that's fixed in TC 4.0.1 My rc script starts both TomCat and Apache (i.e. not separate scripts) with a sleep 10 between the commands. This appears to work but who knows :) I don't think further separating the scripts (i.e. S2 and S99) would make much difference in terms of time.
