Announce Melati 0.55
Melati 0.55 is now available for download from http://melati.org Version 0.55 introduces the following enhancements relevant to this mailing list readership. o - support for Tomcat (JSDK 2.2) What is Melati? (quick read) Melati allows you to define the fields and records for you application in one place. These are then immediately available to all parts of your application: o - your template engine o - your business objects o - your database This considerably simplifies (and speeds up) web application development. Try it :) What is Melati (more detail): Melati is a tool for building Java-programmed websites backed by a database. It provides the following features: o- a generic database administration system, allowing the site manager to edit both the contents and the structure of the database through a simple web based interface. have a look at this: http://www.melati.org/melati/org.melati.admin.Admin/melatitest/Main o - full integration with POEM (Persistent Object Engine for Melati). POEM provides o - an API where the database to be seen as a collection of Java objects, via a (genuinely!) easy-to-use transparent persistence layer on top of JDBC. o - a low level security model allowing restrictions to be placed on tables, rows and fields. o -industrial-strength open source object database technology, delivering ODMG 3.0 compliant Java support. o - close integration with the Velocity and Webmacro templating engines. o - rapid templating mechanism, using templets (sub-templates) for rendering interface elements (eg HTML input boxes, dropdowns), and providing an easy interface with persistent objects. o - cookie-based or HTTP-based login provoked automatically by access control failure. Melati's design builds on our experience with previous systems we have deployed successfully on a number of commercial sites: we feel that it enables a particularly elegant and productive way of working. Melati is released under a dual ASF Style / GPL license.

Bug with tomcat ?
hiii, i am using RedHat 7, apache 1.3.20, tomcat 3.3-m3. When ever i send a request for a jsp page which does not exist , i am returned a response CODE 500. Which should be 404 . Regards, saurabh
Re: java-linux-tomcat configuration problem
Hi, Many ppl using 1.3.1 specifically have noted huge memory usage increases (leaks) which either take a long time to clean themselves up or are permanent. The issue has been reported by ppl using JNI, tomcat, app contexts etc etc so is a JDK bug. Sun still haven't fixed it (I just checked) Maybe 1.4 fixes it, but that is still in Beta so I wouldn't use it on a deployed platform just yet. Apparently using 1.3 fixes it, but its a real pain to find. Sun don't actually advertise its whereabouts on their site. The blackdown JDK doesn't seem to have this problem so you could try that (I don't know where it can be found) Hope that helps, Adam.

Re: java.lang.SecurityException: sealing violation?
Hi, Oh dear. TOMCAT IS A JAVA APPLICATION!!! The only time you should need to recompile it is if you want to use JSSE (For SSL) You might want to recompile mod_jk or the like, but thats completely different. You may be getting an error as you do not have the correct privileges to execute the commands in the script. (If it needs to access something from the JDK in Security) Why didn't tomcat work the first time??? Its all very well complaining about it but if you don't give precise details about OS/Tomcat/JDK versions and what happened then we can't help. Post exact details and I'll take a look. Adam.

Hi,
You could catch the exception in forwardTest.jsp, set the attributes in the
catch clause, then rethrow the exception.

Hello,
I wrote a 'LoginServlet' which forwards a request to 'forwardTest.jsp'.
If any exception is thrown inside 'forwardTest.jsp', I pass error context
to the 'error.jsp' page.
Before writing a real program, I wrote a very simple test program, which
were attached with this email.
Everything works fine except the error page.
Since I needed to pass some information of 'forwardTest.jsp' to
'error.jsp', I used session to store the informtion as an object named
'context'. Then, 'error.jsp' will call 'session.getAttribute(context)' to
get 'context'. However, in some cases, session of 'error.jsp' is different
from session of 'forwardTest.jsp' and 'LoginServlet', so
'session.getAttribute(context)' returns null, which is not good and I
don't know why 'error.jsp' uses a different session in some cases.
How I can solve this situation?
(I think I can pass 'context' object from 'forwardTest.jsp' to
'error.jsp' using 'request.setAttribute(context, context)' but I am not
sure whether this kind of approach is valid with other JSP/Servlet
containers.)

Re: Tomcat Frames
The same type of problem occured, one one workstation but not the other. I renamed index.html to index.jsp and it worked. Stephane
Re: Tomcat Frames
I think I've solved my problem. I don't know if it'll help anyone else experiencing this, and it's hard to tell if I've really fixed it this time, because the situation seems to get better sometimes, and then gets worse again, but so far it looks like it's okay now. I use UD4 to write my JSPs, and the MM code does not close all the connections. It closes the recordsets and the database connections, but it does not explicitly close the preparedStatements, and that results in memory leaks. I think the problem is exacerbated when you use frames, because the connections never get closed, the frames are always displaying and getting refreshed, and so, eventually, it takes longer and longer to refresh the pages. I've gone through all my pages and added the statement to close the preparedStatements, and the pages seem to be loading correctly now every time, regardless of how often I refresh them.

Hi Connie, I think the first thing you should do is read the Apache docs on virtual hosting here: http://httpd.apache.org/docs/vhosts/index.html Then go to the archive here: http://mikal.org/interests/java/tomcat/index.jsp and do a search on virtual host jeff -- this will pull up all my previous posts on virtual hosting, including examples of my config.

What did you put in the NameVirtualHost ? should be the IP of the default server, right ? According to the documentation, you have to set the IP to either way ( not 100% sure, but I read before ) But, why don't you put your default sever into the virtual host too ?? If it can be only recognize by the NAME the client enter in the browser. Another solution is you are going to set another IP for all virtual host, but it involves modifying the DNS entries.

I have set up the server such that it serves a default web server, ssl server (being set up as a virtual host with using port 443), and a virtual host (with using port 80). But the document root for default web server and virtual host is mixed up. My virtual host and default web server are using the same IP address. When I type the default web server, the welcome file for virtual host displays. When I type the virtual host, the welcome file for the virtual host displays as well. However, if I specify port 8080 (the HTTP port for tomcat) in the url (for testing tomcat only without going thru apache), the default web url would display the correct welcome page. In my httpd.conf, I have declared DocumentRoot d:/jakarta-tomcat/webapps/myapp AND VirtualHost dev.mycomp.com:80 ServerName vh1.mycomp.com DocumentRoot d:/jakarta-tomcat/webapps/vh1 JkMount /*.jsp ajp12 JkMount /servlet/* ajp12 JkMount /email/* ajp12 Directory d:/jakarta-tomcat/webapps/vh1/META-INF/ AllowOverride None deny from all /Directory Directory d:/jakarta-tomcat/webapps/vh1/WEB-INF/ AllowOverride None deny from all /Directory /VirtualHost Do I miss anything?

Re: java-linux-tomcat configuration problem
I would try the IBM JDK before Blackdown (before Sun, too...), but that's just my personal choice.

The issue has been reported by ppl using JNI, tomcat, app contexts etc etc so is a JDK bug. Sun still haven't fixed it (I just checked) Maybe 1.4 fixes it, but that is still in Beta so I wouldn't use it on a deployed platform just yet. Apparently using 1.3 fixes it, but its a real pain to find. Sun don't actually advertise its whereabouts on their site. The blackdown JDK doesn't seem to have this problem so you could try that (I don't know where it can be found) Hope that helps, Adam.

Jasper compiler from the command line
Hi, I've been developing a webapp with Tomcat for a while now and one of the problems I keep running up against is that when I make changes to my underlying beans (ie. change of method signature) which are used by the jsp pages in my webapp that I sometimes forget to make the necessary changes across all jsps in the webapp which make use of the changed beans. To help avoid this problem I created an ANT task to automate running the Jasper compiler (see my recent message on [EMAIL PROTECTED]). And then let ANT report the compilation problems to me. Before I was able to get this task to run I had to make some modifications to the jasper compiler because it wasn't operating properly for my jsps. The problem was that in my jsps I make use of static includes which are referenced via relative file paths in the %@include file=../include.jsp% directive by jsps which are in various subdirectories of the webapp. This was causing problems for the jasper compiler because the context wasn't being set properly in the CommandLineContext.java object to be able to handle relative includes in pages which were in some subdirectory of the webapp. Anyways, I made some small changes to the constructor of CommandLineContext to fix the problem. It works properly now, and it doesn't seem to introduce any other problems. I've attached my version of CommandLineContext.java as well as a diff file. Hopefully someone with more appropriate access levels can look over and check-in the changes. The diff file is a little screwy for some reason, but I'm not good enough with CVS to be able to figure how to fix it. If you have any questions send me a reply. Thanks Alex. P.S. Thanks to all the people who work on Tomcat. I've been using it since the first beta and it just keeps on getting better. /* * $Header: /home/cccvs/cc/working/alex/CommandLineContext.java,v 1.2 2001/07/15 00:42:42 cccvs Exp $ * $Revision: 1.2 $ * $Date: 2001/07/15 00:42:42 $ * * * * The Apache Software License, Version 1.1 * * Copyright (c) 1999 The Apache Software Foundation.

If that is the case, the process name is jk_nt_service.exe. Unless you have another process that is constantly trying to grab that port, Tomcat is still running - NT does free the ports when the process dies. Also, 2000 (and I believe NT) ship with netstat. Using netstat -a you can determine which ports are currently in use (and their state).
