Startup error
TC4.0.2 jdk1.4.1 RH7.1 Everything went fine until this morning, when TC stopped loading my application when started. Catalina.out shows: ERROR reading java.io.FileInputStream@88e2dd At Line 2340 /web-app/servlet-mapping It seems to come from web.xml, because if I add a blank line, the error line changes. But I cannot figure out why: line 2340 is /servlet-mapping and closes a well-formatted servlet-mapping declaration. Please help.

Server memory usage
TC4.0.4, jdk1.4.0_01, RH7.3 on P3-633MHz, 256MB RAM When I start TC, I find 28 Java processes for a total of 829MB used. Is there a way to make it use less memory, so that it runs only out of RAM?

Re: REPOST: Problems serving PDF to Netscape browsers
I do the following (call it whatever you want :-|, the reasons are beyond technical): I have an applet that calls the servlet that generates the pdf stream. The applet then saves the stream as a file on the local HDD and opens the file with Acrobat Reader. Of course you need to check whether the file is already there, open etc. HTH -Original Message- From: Jeff Larsen [EMAIL PROTECTED] To: [EMAIL PROTECTED] [EMAIL PROTECTED] Date: Tuesday, May 14, 2002 12:01 PM Subject: REPOST: Problems serving PDF to Netscape browsers I've made no progress on this, so let's try again. My dynamic PDF is working perfectly with MSIE 4, 5, and 6, but I'm still having problems with Netscape (ver 4 and 6) and the Acrobat (ver 4 and 5) plugin. I've tried this on various client machines. With both NS4 and NS6, I just get a blank screen when I request my dynamic PDF. They don't even show the Acrobat toolbar. The similarities end there. In NS4, the first request does not launch the AcroRd32.exe process. In fact, it fails to read the entire output of the servlet and Tomcat (4.0.3) spits out a Broken Pipe exception to the logs. If I hit Reload, however, I get my PDF and the plugin works. According to the Apache logs, the first unsucessful request returns 6144 of 21212 bytes before the broken pipe. On the Reload, the Apache log shows TWO requests returning the full 21212 bytes and Netscape displays it in the plugin. In NS6, the first request DOES launch the plugin executable, but that's as far as it gets. Reload doesn't help. My Apache server reports the correct number of bytes for the full PDF request, so the data seems to be getting to the browser. No exceptions are thrown by Tomcat. In both NS4 and NS6, it works if I configure Acrobat to be launched as an external application instead of a plugin. But it is not a viable option to impose that configuration on our customers. I use a servlet mapping that sends requests for xxx.pdf to my servlet, thus the browser sees a .pdf filename. I also use setContentType(application/pdf). There are known problems with MSIE and unknown ContentLength with PDF so I create the PDF in a ByteArrayOutputStream so I can know and set the ContentLength before writing to response.getOutputStream(). To take the dynamic nature of the PDF out of the equation, I was able to reproduce these problems --sometimes-- when serving static PDF files via Tomcat. - Original Message - From: Jeff Larsen [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, May 09, 2002 1:44 PM Subject: Problems serving PDF to Netscape browsers I'm running out of hair to pull out here... My ultimate goal is to serve dynamically generated PDF documents generated with iText. I've got it working just fine with MSIE. However, I was just getting blank pages with Netscape (and it wasn't even showing the toolbar for Acrobat). With NS6 I could at least see that it started an AcroRd32.exe process, but NS4 didn't even get that far. So, I did some tests to rule out some variables. I grabbed a handful of pre-generated PDF files and stuck them on my Apache 1.3.23 server. All browsers could display the PDFs just fine. Then I set up Tomcat 4.0.3 to server the same files directly without going through Apache. MSIE worked, but both NS browsers gave a blank page with no Acrobat plugin toolbar. Again NS6 managed to start an Acrobat process, NS4 didn't.

Hi all.
I'm crossposting this to two mailing lists, I think poth parties are
concerned.
Finaly got some time to work on my project on Tomcat and I ran into
problems.
Mostly these problems stem from the inconsistent documentation that
accompanies
Tomcat 4.0 distribution. And it would appear that PostgreSQL is also in
error
(see below).
I have:
- Tru64 UNIX 4.0D (a.k.a. Digital UNIX)
- Java 1.3.0 SDK
- Tomcat 4.0 final release
- PostgreSQL 7.1.0
- PostgreSQL JDBC 2.0 compliant driver
QUESTION 1: How do I go about setting it up with Tomcat?
I have tried the following:
- placed postgresql.jar in ${CATALINA_HOME}/common/lib/
- added CATALINA_OPTS=-Djdbc.drivers=postgresql.Driver
- restarted Tomcat
My JSP file is:
%-- My first go at PostgreSQL and JSP --%
%@ page info=test import=java.sql.*, javax.sql.* %
%!
Connection conn = DriverManager.getConnection(
jdbc:postgresql://localhost/mercury, test, test00 );
String query = SELECT * FROM div;
%
[SNIP]
/html
When I run it, I get the following error:
---
org.apache.jasper.JasperException: Unable to compile class for JSP
...
Root Cause:
java.lang.NumberFormatException: postgresql
...
---
This would imply that I'm either using a wrong connection string or the
driver
isn't loaded, right?
QUESTION 2: Now this may sound dumb, but... PostgreSQL docs state that I
should
load driver with -Djdbc.drivers=posgresql.Driver, but if I list
postgresql.jar
file, I see it is org.postgresql.Driver. Is this a typo in the docs?
Nix.

Re: JDBC Connection Pool Theory ??
Thank you very much. Aside from lower speed (open a db connection every time a servlet requires it), are there any other inconveniences or risks if not using a connection pool? -Original Message- From: C. Schlegelmilch [EMAIL PROTECTED] To: [EMAIL PROTECTED] [EMAIL PROTECTED] Date: Saturday, September 22, 2001 2:20 AM Subject: Re: JDBC Connection Pool Theory ?? A pool of a fixed number of connections is generally initialized right at startup of the web application. From then on in, when a user of a wep app requires a connection, it pulls it away form the pool and returns it when its done. Because all users of a web app effectively share all of the connections of a pool, there is never one connection reserved for one user. Its generally a better use of resources not to. But now that I think of it, there is nothing stopping you from assigning a user to a connection in a pool. That would require some interesting design work to make it slick, but its possible. While this may not solve your current issue, give this a try: http://www.webdevelopersjournal.com/columns/connection_pool.html The code looks very similar to some of the class solutions. --- Mihai Gheorghiu [EMAIL PROTECTED] wrote: I've been looking at some pooling examples and I must admit I'm still not clear whether it is possible to have db connections with the username and password of the web/java user, or the database sees n connections with the same username and password generated by the pool manager.

We had our web development class develop their own software for connection pooling.

They are using Professional Java Server Programming as a reference and it has some interesting sections on Connection Pooling. This is good if you're only running a simple application. It was also noted that this resource did not address any synchronization issues which is very important (the last thing you want is two seperate threads getting a reference to the next free connection at the same time). This is really the only big gottcha that we found in a simple implementation. --- Jon Shoberg [EMAIL PROTECTED] wrote: Can anyone suggest or point to readings on JDBC connection pool theory?

Re: Where is that cache?
Multumesc mult! Stii vorba cu intins degetul si luat mana. Acum am dat in alta aia. Am structura tomcathome/webapps/development/WEB-INF/classes/Test In development am test.html, pagina de start, care incarca un applet, TestApplet.class, care e in Test. Nu reusesc sa potrivesc parametrii code si codebase in test.html ca sa incarc TestApplet. Appletul e Swing si in IE am plug-in. test.html a fost generat cu html converter initial, apoi am schimbat proiectul/pathul si nu reusesc sa le dau de capat lui codebase si code.

The applet included four Swing elements. Because an error kept coming regardless of what I did, I decided to remove one element from the applet. To my surprise, the old, four-element applet keeps loading. The IDE (Netbeans) has the context mounted in its filesystem (I have both .java and .class files in .../webapps/development/WEB-INF/classes/), so that what it displays, the user should see too, via Tomcat. I cleared IE's Temporary Internet Files folder, manually deleted the html file from there, checked that there is no proxy enabled, re-built the project... Any suggestion will be highly applreciated.
Re: Yet another newbie question
Bull's eye! Thanks a lot. I had noticed the Java console pop up when the Sun applet was loaded and looked at the source and did not figure out what that classid was for. -Original Message- From: Amthauer, Heiner [EMAIL PROTECTED] To: '[EMAIL PROTECTED]' [EMAIL PROTECTED] Cc: '[EMAIL PROTECTED]' [EMAIL PROTECTED] Date: Wednesday, August 29, 2001 2:18 AM Subject: AW: Yet another newbie question Hi there, this is not a tomcat-problem. Your browser comes with Microsoft Java VM which is not able to handle any stuff from the javax.swing package. Furthermore it does not recognize that it should use the Java Plugin since it is not enought just to install the plugin. You need to run the htmlconverter on your html-file. It converts the applet-tag into something like OBJECT classid=clsid:8AD9C840-044E-11D1-... which actually causes IE5 to start the plugin. You can easily check this by enabling the java-console in your plugin-control-panel. If I am right, the java-console should pop up when showing the swing test applets from sun but it does not pop up, when showing your own html-page (close your browser before loading the pages, otherwise this effect doesn't work). In the latest plugin versions, you can also verify that the plugin is loaded by the little java guy showing up in your taskbar. You can retrieve the htmlconverter from java.sun.com. Up to Java version 1.3.0_01 it is available, separatly. In later versions, it is bundled togehter with the J2SDK. However, you can use the htmlconverter for 1.3.0, which will work with any later versions of the JRE and plugin, perfectly well. Hope this helps. regards Heiner -Ursprüngliche Nachricht- Von: Mihai Gheorghiu [mailto:[EMAIL PROTECTED]] Gesendet am: Dienstag, 28.

Netbeans to Tomcat
What steps do I need to take in order to have my work in Netbeans installed properly under Tomcat? Thank you all.
Re: SSL capable
Thanks a lot. Got the source, the how-to, and the jsse jars from Sun. I guess that for the actual build process I have to look in the Ant manual? Is this presented anywhere else?
