5.0.16 sample can't deploy, gets zip exception
hi, just tried 5.0.16 (trying to get this to work for a class i am teaching
this thursday). all is well until the install. i get a:
install:
[deploy] FAIL - Encountered exception java.util.zip.ZipException: error
in opening zip file
BUILD FAILED
file:H:/htdocs/ltu/servlets/sample/build.xml:90: FAIL - Encountered
exception java.util.zip.ZipException: error in opening zip file
the complete output from the build is at the end. i modified the build file
by making install depend on dist and removed a lot of comments.
the myapp.war unjars fine with:

if i unpack shut down tomcat and put myapp-0.1-dev.war (or renaming to
myapp.war) into webapps and restart tomcat, i can get to where he unpacked
it, the jsp says:
Context Path: /myapp
Path Information: null
Query String: null
Request Method: GET
Servlet Path: /hello.jsp
but the servlet class can not be found as it is asking for hello, i guess
this is because i did not alter the .xml files where the mappings live.
iirc, there was some mention of supplying your own.
has anyone gotten the sample to install from ant?
if not, where can find the doc on making my own .xml files to define the
mappings (assuming that works) instead of munging tomcat's files or should
i just go back to doing it the old way?
any pointers would be appreciated
thanks

Tomcat and Log4J
All,
I have been trying all day to get Tomcat and Log4J to cooperate. I have
looked through many posts to this mailing list but have been unable to find
any extra information that helps me.
I am running Tomcat 4.1.27 on a Windows 2000 machine. My web app has
log4j-1.2.8.jar in its WEB-INF/lib directory. I have a config file called
log4j.xml in my WEB-INF directory. To load the configuration, I have a
ContextStartupListener implementation with this code in it:
//first things first - initialise the logging sub-system
try {
System.out.println("Initialising Log4J . . .");
String configFile =
WebAppContext.getContextParameter("log4j-config-file");
//provide default
if ((configFile == null) || ("".equals(configFile.trim(
{
configFile = "/WEB-INF/log4j.xml";
}
String filename =
getServletContext().getRealPath(configFile);
DOMConfigurator.configure(filename);
System.out.println(". . . done");
} catch (Throwable t) {
System.err.println("Exception occurred: " + t);
t.printStackTrace(new PrintWriter(System.err));
}
//now create the log
log =
org.apache.commons.logging.LogFactory.getFactory().getInstance(StartupListen
er.class);
log.trace("trace enabled");
log.debug("debug enabled");
log.info("info enabled");
log.warn("warn enabled");
log.error("error enabled");
log.fatal("fatal enabled");
My log4j.xml file is defined as:
http://jakarta.apache.org/log4j/";>
As you can see, I have tried to redirect all logging for my webapp to a
custom log file. If I set the log4j.debug system property to true, I can see
that Log4J is successfully finding and using my configuration file. Indeed,
the custom.log file is created. However, none of my log statements are
directed to this file. Instead, they go straight to the console as per
usual. Also, the debug level is the same as usual (ie. level is info instead
of debug as specified in config file).
What's really interesting is that there is some output in custom.log.
However, this output belongs to JBoss client classes (my application
utilises JBoss as an app server). Note that I am running Tomcat standalone -
not as part of a JBoss installation. Here is a sample from custom.log:
2003-12-17 14:54:13,653 DEBUG
[org.jboss.mq.referenceable.SpyConnectionFactoryObjectFactory] Extracting

2003-12-17 14:54:14,134 DEBUG
[org.jboss.mq.referenceable.SpyDestinationObjectFactory]
SpyDestinationObjectFactory->getObjectInstance()
It seems Log4J is being used for JBoss client classes but not for my own.
What am I doing wrong here? I have also checked to ensure that
${CATALINA_HOME}/common/lib does not contain any logging-related JARs except
for commons-logging-api.jar. Similarly, I have made sure that my web app
does not contain any logging-related JARs except for log4j-1.2.8.jar.
Sorry for the long post and thanks for even reading this far. I'd appreciate
any help anyone can offer.
Thanks,
Kent

Re: Problems with HTTPS in Tomcat 5
It depends on your needs. If your app is going to be connected to the internet, then you need Verisign/Thwate/. If it is an intranet app, then you just need to distribute your signing cert to people, and have them install it.

Re: how to change default SMTP port 25 in java mail?
This is not off topic for the tomcat user list Chris. How would one do this in tomcats configuration? By adding an environmental variable to resource configuration in the server.xml file of tomcat. A proper subject for the tomcat user list indeed. See the configuration doc for tomcat if you have further questions on configuring the javamail resource in tomcat's server.xml http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-resources-howto.html here's an example, the reference that Chris provides details all the parameters you can set for the Mail Session via this method. ... mail.smtp.host localhost mail.smtp.port 25 ...

To avoid this problem,
<% session.invalidate(); %>
The value of foo is: ${applicationScope.foo}
.
But I don't like this manner.
Then, how can I invalidate session safely?
Any suggestion or any English correction helps me.

Take a look at the Tomcat logfiles in TOMCAT_HOME/logs Always start there. 2.) Make sure Tomcat can find the javac compiler. Do you have a full j2sdk installed or just a JRE? Tomcat will run with a JRE but won't be able to compile your JSPs without access to javac. If not, go to http://java.sun.com and get a full j2sdk. Is your JAVA_HOME evironment variable set? Type: echo $JAVA_HOME at the shell to verify. It should point to the root directory of your j2sdk. Example: /usr/local/j2sdk1.4.2 Is your JAVA_HOME evironment variable PROPERLY set? Type: $JAVA_HOME/bin/javac at the shell. If you get a "Command not found" message, it's not. Another way to make sure that Tomcat can see your javac compiler is to run (not just look at, but run) the JSP examples that ship with Tomcat. 3.) Check the permissions of the directories and files that you've created and make sure that that whatever user that is running Tomcat has permission to access those files.

Re: Default context for web app
Didn't work. So I can't do what you're doing. Strange. Are you dead certain you don't have an /eSM/ context? Adam Hi Adam, It's a bit hard to tell for certain since I have disabled the manager app. However, I can tell you that there is only one directory below work/Standalone/localhost and it is called "_". Tomcat used to create two directories here when it started two contexts - "_" and "eSM". Also, when I start Tomcat on the command line I can see that my webapp is only started once. I have a ServletContextListener implementation that outputs version details etc. I used to see this information output twice but now I only see it once.

Cannot Create Resource Instance
I get "Cannot Create Resource Instance" when attempting to open the database
connection defined by the following entry in server.xml
factoryorg.apache.commons.dbcp.BasicDataSourceFactory

driverClassName
com.microsoft.jdbc.sqlserver.SQLServerDriver

The java that attempts to reference this is

DataSource source = (DataSource)context .lookup("java:comp/env/");
Connection con = source .getConnection();
Statement statement = con .createStatement();
Any clue what I'm doing wrong here?

Here is our architecture. 5 web servers (web1 - web5) and 4 java servers (java4-java7) Each Webserver is using the same version of mod_jk (version 1.2.5) and apache (1.3.27). Each java server is running the same version of tomcat (3.3.1a). Red Hat is being used on both web servers and java servers. When we have mod_jk load balancing turned on (see config at url below) the following errors (see http://titan.cbc.ca/~bcrosby/tomcat.txt) in tomcat.err are present. On the webserver, the mod_jk error file shows: [Tue Dec 16 18:18:27 2003] [jk_ajp_common.c (1303)]: ERROR: Client connection aborted or network problems Turning mod_jk load balancing off fixes this problem. A copy of the workers.properties file is available at http://titan.cbc.ca/~bcrosby/workers.txt. Questions: 1. What is the definition of "client" according to mod_jk. In the error message from mod_jk (see above) "client connection aborted" means tomcat aborted the connection (tomcat being the client) or apache/mod_jk aborted the connection. 2. Are there any values (like socket_keepalive) that are missing in my workers.properties file?

Please excuse my ignorance, I'm trying to achieve clustering with Tomcat
5I've read the following in the Tomcat 5 documentation:
=
To run session replication in your Tomcat 5 container, the following
steps should be completed:
-->All your session attributes must implement java.io.Serializable
===
Okay. I've completed all the other steps (uncomment the
element along with the , and added the in
web.xml)I'm trying to code a simple object that implements
java.io.Serializable to store in a session and here it is.
package com.shawmut.session;
import java.io.Serializable;
public class SerializeSession implements Serializable {
public static String testString = "";
public void setString(String stringValue){
this.testString = stringValue;
}
public String getString(){
return this.testString;
}
}
ok.Now I want to put this in the session.
<%
if(session.getAttribute("ss")== null){
SerializeSession ss = new SerializeSession();
ss.setString("Booo! And I created my
session on Tomcat 1 Node");
session.setAttribute("ss", ss);
}
%>
Whats going on here?.I unplug the patch cord ( docs says it's a bad
idea) from one of the boxes and hit a jsp on the working node that does
the following..and the session doesn't carry over to the working
node
<%
if(session.getAttribute("ss")!= null){
SerializeSession ss2 =
(SerializeSession)session.getAttribute("ss");
%>
SESSION:<%=ss2.getString()%>
<%
}
%>
Basically what I'm looking for is an example of serializing session
attributes as noted above Any Help here will be greatly
appreciated..

RE: Apache-Tomcat connectors... why??
Thank you Howard and Jim, I will look into mod_proxy. Things seem a little more complicated because I am attempted to integrate with the JBoss tomcat bundle. Obviously the configuration is a little different here and most howto's require a little bit more thinking about as to where to find the files etc... Im not sure about using tomcat as a static content server. Apache has many features that tomcat doesnt as it is designed for this task. It might solve the problem, but the powers-that-be are quite keen on full integration. Im not sure that servlets do require anything extra at HTTP level. Perhaps I am missing something but due to the relative simplicity of HTTP and the fact its stateless I would assume that the servlet container cant require anything extra. From the browsers perspective it is requesting a static resource, by name, from a domain. The proxying route would have the added advantage of not having to reconfigure mod_jk(2) everytime a new web app is added. The browser says "Give me /index.jsp", apache says "I cant find index.jsp, but i know about THIS http server (tomcat), that might", tomcat says "yup, i can do that for you, here it is", apache says "Here you go... i found it eventually"... all over HTTP. It seems to make a lot of sense to me, but as you say, if this simple solution has not been shouted about, it will mean there is a fundemental flaw... lots of smarter guys than me working on this stuff =o) Thanks again for your help! > -Original Message- > From: Howard Jim [mailto:[EMAIL PROTECTED] > Sent: 16 December 2003 19:34 > To: Tomcat Users List > Subject: RE: Apache-Tomcat connectors... why?? > > > I believe what you are referring to is the ProxyPass Directive > > http://httpd.apache.org/docs-2.0/mod/mod_proxy.html#proxypass > > I have used this before, but haven't played with it as a way to > reference the app server.

Re: CGI not working on Tomcat 5.0.16?
The only CGI that I tested with is a log analysis package called AWStats (http://awstats.sourceforge.net/) which primarily consists of a single .pl file. It also seems to use some .pm library files. It has always worked great with Tomcat 4.1. I can't get it to work with Tomcat 5 though. I'm hoping that someone will chime in and let me know if CGI works for them on Tomcat 5.

Gotcha, so the datasource gets stuck into a naming directory, and then you
can grab it via JNDI and use it that way.
The benefit being that a sysadmin can change the datasource via server.xml
rather than having you rewrite the code.
Right?

The main advantage is that you can use a connection pool like
jakarta-commons-dbcp which saves you a lot of runtime. The second
advantage is that you can configure the connection parameters like db
URL, username, password and the like on the fly without editing java
sources or redeploying your application.

Not a bad link, but I have to comment on the guys suggestion about changing the catalina.sh script. Here's a quote: "In my many years of consulting, I have learned not to rely on environment variables which can be unset by ignorant or malicious people" In my many years of consulting, I've much more often encountered problems with people tampering with script files that should have been left alone. Ever do an export JAVA_HOME= to explicitly pick a JVM and be stumped by a bug still happening . . . only to find out that someone took at upon themselves to change a script that you know well, and to manually set JAVA_HOME withing that script? This much more sinister than missing environment variables. If you're very afraid of environment variables not being there or being wrong, then make a script file that sets a few variables and then calls the original script. Or some variant of that.

The main advantage is that you can use a connection pool like
jakarta-commons-dbcp which saves you a lot of runtime. The second
advantage is that you can configure the connection parameters like db
URL, username, password and the like on the fly without editing java
sources or redeploying your application.

RE: JDBC from TagSupport
i have it setup for sybase and mine looks like this in the server.xml:
-
factory
org.apache.commons.dbcp.BasicDataSourceFactory
maxActive
10
maxIdle
5
maxWait
1
driverClassName
com.sybase.jdbc2.jdbc.SybDriver
url
jdbc:sybase:Tds:database_hostname:5000/your_dbname?JCONNECT_VERSION=6
username
your_userid
password
your_password
-
of course i also got a .jar file (jConnect 5.5) from sybase that i guess
provides the "com.sybase.jdbc2.jdbc.SybDriver"
and then in the JSP u have something like this to reference the context
and setup the connection:
-
String s = "java:comp/env";
String t = "jdbc/a_sybase_datasource";
InitialContext initCtx = null;
try
{
initCtx = new InitialContext();
}
catch(Exception e)
{
out.println("");
out.println("");
out.println("failed: initCtx = new InitialContext();");
out.println(e + " : " + e.getMessage());
out.println("");
}
Context envCtx = null;
try
{
envCtx = (Context)initCtx.lookup(s);
}
catch(Exception e)
{
out.println("");
out.println("");
out.println("failed: envCtx = (Context)initCtx.lookup(" + s +
");");
out.println(e + " : " + e.getMessage());
out.println("");
}
DataSource ds = null;
try

RE: Apache-Tomcat connectors... why??
I believe what you are referring to is the ProxyPass Directive http://httpd.apache.org/docs-2.0/mod/mod_proxy.html#proxypass I have used this before, but haven't played with it as a way to reference the app server. If it were that simple, I imagine it would have already been done. I am just getting going with the connectors, but things like parameters, servlets, and the like have their own needs which may require a closer integration with the webserver than can be provided by a simple reverse proxy setup. If all you need is the reverse proxy setup, then perhaps you don't even need the webserver. Just let tomcat serve it all, then all your connector worries are moot.

Hello all, Hopefully I picked a good list to bring this topic up on. There were several candidates.

Re: Apache-Tomcat connectors... why??
http://jakarta.apache.org/tomcat/faq/connectors.html In a nutshell, tomcat anc apache talk to each via the AJP protocol. The AJP protocol is like the HTTP protocol but more efficient for various reasons. An alternative to having apache talk to tomcat via AJP can also be mod_proxy sounds similar to your situation below. mod_jk and mod_jk2 are both modules written in C to be used by apache (or insert server here) jk2 is a rewrite of jk but for the same protocol. So the configuration of the jk vs jk2 is different. On the tomcat side, it really doesn't know that the apache instance is using mod_jk or mod_jk2. -Tim Wesley Hall wrote: Hello all, Hopefully I picked a good list to bring this topic up on.

That works great in a windows environment. But on Linux machines,the line will always return 127.0.0.1 Tim Funk <[EMAIL PROTECTED]> wrote:Ideally use a string for uniqueness, not an int. For an int is too small across a cluster.

I have a web application where I need to generate a unique id(of type int) for each request. I've got 8 tomcats running across 4 machines, 2 tomcats each machine. It's pretty simple to generate a unique id with one tomcat, but with mulitple tomcats, it gets pretty tricky.

I am about to setup Tomcat under a new Linux 2.6 kernel with 2 Athlon MP processors. Since scheduling, threading, and SMP have been much improved in the new kernel I wonder if it will add to performance.

Re: How do you generate a unique number for each request across muliple tomcat instances?
Ideally use a string for uniqueness, not an int. For an int is too small across a cluster. To get a unique string, concatenate your IP address with java.rmi.server.UID(), for example: String guid = InetAddress.getLocalHost().getHostAddress() + (new java.rmi.server.UID()).toString()); See the javadocs on UID for more info. -Tim Tom Ly wrote: I have an application where I need to generate a unique int for each request that comes in. I've got about 8 Tomcat instances running spread across four machines(two tomcat's each machine). It's pretty simple with one Tomcat, but with mulitple Tomcats it gets tricky. I tried using InetAddress to get the ip address of the current machine and use that to set the range for each tomcat(since the ip address will always be unique), but since I'm using Linux, it'll always return 127.0.0.1 as the ip address, so I can use class InetAddress.

Re: Tomcat 5 Clustering
download a load balancer
balance.sourceforge.net or a perl balancer called "pen" (google)
the shut down one tomcat, after initial access, the system will fail over.
pulling the network cable without any other failure has not yet been handled
as a failure scenario

Subject: Tomcat 5 Clustering
Hello All:
Please excuse my ignorance, I'm trying to achieve clustering with Tomcat
5I've read the following in the Tomcat 5 documentation:
=
To run session replication in your Tomcat 5 container, the following
steps should be completed:
-->All your session attributes must implement java.io.Serializable
===
Okay. I've completed all the other steps (uncomment the
element along with the , and added the in
web.xml)I'm trying to code a simple object that implements
java.io.Serializable to store in a session and here it is.
package com.shawmut.session;
import java.io.Serializable;
public class SerializeSession implements Serializable {
public static String testString = "";
public void setString(String stringValue){
this.testString = stringValue;
}
public String getString(){
return this.testString;
}
}
ok.Now I want to put this in the session.
<%
if(session.getAttribute("ss")== null){
SerializeSession ss = new SerializeSession();
ss.setString("Booo! And I created my
session on Tomcat 1 Node");
session.setAttribute("ss", ss);
}
%>
Whats going on here?.I unplug the patch cord ( docs says it's a bad
idea) from one of the boxes and hit a jsp on the working node that does
the following..and the session doesn't carry over to the working
node
<%
if(session.getAttribute("ss")!= null){
SerializeSession ss2 =
(SerializeSession)session.getAttribute("ss");
%>
SESSION:<%=ss2.getString()%>
<%
}
%>
Basically what I'm looking for is an example of serializing session
attributes as noted above Any Help here will be greatly
appreciated..

JDBC from TagSupport
Quick question. I see that one can configure a JDBC datasource in their server.xml file and their web.xml file. What does this get you? Every example that I have read tells me that I need to open a JDBC connection just about the same as I would from any other java application. What is the purpose of setting up a JDBC datasource in these files? Is it only good for userdatabaserealm?

Re: IIS port 80 vs Tomcat port 8080.
You might get a million versions of this answer. Here's one. JK is what you want: http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jk2/index.html You'll get an ISAPI DLL that forwards requests, using the AJP protocol (NOT http), to a special service running on Tomcat on port 8009 (this is the default). This is a bit of a nuisance for Windows, since you have to enter registry keys. But the instructions are pretty good and it's not hard. Just make sure to read about Workers, and watch the syntax on your workers.properties.

Vhosting with Apache 2 & jk
Hi all, I have several domains hosted by Apache 2.0.48, and I'd like to start adding JSPs to each domain. I have Tomcat 4.0.16 running on a different host, and am using JK to connect them. Virtual hosting is working on Tomcat, if I go straight to the Tomcat host on port 8080. JK does appear to be forwarding requests over to Tomcat. The problem is, the requests always go to the default domain on Tomcat (webapps/ROOT). It's almost as though the file portion of the URL is getting forwarded to Tomcat, but not the domain. My worker properties is pretty much the sample -- I've included it below. I've also included the lines from my VirtualHost block for the offending domain.

redirecting based on role name
hello everyone, I have a site that uses form authentication thru JDBCRealm. I have my webapp root as /ROOT/ with 3 directories. I have also set up the web.xml file with 3 different security constraints based on the 3 directories in /ROOT/. My questions is, can I redirect a successful login to a specified directory based on the role_name I assigned the user in the mysql database? For example, if I have configured bob with the role_name of admin. Can I redirect his url to /ROOT/ADMIN by retrieving his role_name? Can any one point me in the right direction?

Re: Exception loading sessions from persistent storage
Yes you are...
Tomcat supplies the needed j2ee resources.
When you declare your vPar class, just make sure that you specify that it
implements Serializable:
public class vPar implements java.io.Serializable{
If you have any nested classes do the same for them.

RE: Using jdk... message box
Eugen - I worked on this same issue some time ago. I ended up just documenting (in the installation instructions) to click 'OK' when that dialog comes up. To my knowledge, there is no way around it. Even moving to a newer version of Tomcat will not work - because the newer 5.x versions wont even install in Silent Mode (or at least that's been my experience). They just halt with a dialog saying that they cant find the JVM (on the same setup that a 4.x version will silent install in). Eden -Original Message- From: Cocalea, Eugen [mailto:[EMAIL PROTECTED] Sent: Tuesday, December 16, 2003 10:33 AM To: [EMAIL PROTECTED] Subject: Using jdk... message box Hello, I am trying to use the installer for tomcat 4.1.12 for windows from another windows program. It works well in silent mode, but the only thing is that I get that message box that says that Tomcat will use 'jdk that was found in...', which seems to be the point where the installer stalls until I click ok. This is a bit annoying, do you know any method that I can get rid of that message box? Thanks. EC - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

localhost works, www does not; why?
This may have been asked many times before, but I can't find it, in part because I don't quite know what to search for and in part because it may not even be a Tomcat-specific issue. But it occurs because I'm trying to make Tomcat work, so here goes... (if I'm wrong and the question needs to be redirected, I'm sure someone will politely point it out to me :) I have Apache 1.3.27 and Tomcat 4.1.27 running under Red Hat 9.0 Linux. The two webservers are connected by mod_jk. When I go to http://localhost from the browser on the Linux box, I get Apache's index page. http://localhost:8080 gets me Tomcat's index page. And http://localhost/examples gets me the Tomcat examples directory listing with an Apache port 80 slug at the bottom. When I drill down to the examples themselves, they work. So I know the Apache->mod_jK->Tomcat connection is correctly configured. But when I try it from the live web, using my domain name, I cannot get to the Tomcat pages. http://www.katzenjammer.us gets me my website. http://www.katzenjammer.us:8080 gets me Tomcat's index page, and, again, I am able to drill down into the examples themselves and they work. But http://www.katzenjammer.us/examples and http://www.katzenjammer.us/examples/jsp/index.jsp get me 404 page not found errors. My webserver sits behind a Netgear firewall router, which has been configured to allow ports 80, 8080, and 8009 to get through to the webserver. Can somebody tell me what I"m doing wrong? Thanks.

an intro into using hidden frames, read it and then go back to google if u
need more info, if u want more help on the javascript in the hidden frame
controlling the visible frame then dont hesitate to ask

I like the idea of this additional hidden frame.
Is there any pointers to where I could start to look at some code for
hidden frames as I have never had the pleasure to create them?
I suppose they would need to be able to communicate with each other
aswell. must be able i suppose.
Ok Ill go have a look at this. Cheeers for all your prompt help.
Del.
Since you guys dealt with this with such ease im stuck on another topic.
last one honestly.
On another hand im trying to call the servlet.
Im using this code
1 URL myUrl = new
URL("http://localhost:8080/servlets-examples/servlet/lbp.LBPServlet?ReceivedEvent=tester2";);
2 HttpURLConnection urlConnection =
(HttpURLConnection)myUrl.openConnection();
Will this code get to the doget() method of my servlet or do i have to
include something additional to get into the servlet doget(). or dopost()?
Using this for event stimulus but doesnt seem to be working just now.

very true, if u try to make the browser hang on for too
long then
eventually something will timeout (either on the client
side or server
side)
so as many here have suggested the best way is to refresh
with javascript
or a meta-refresh
but ... an even nicer solution is to create a hidden
frame that has ur
javascript/meta-refresh code, in this hidden frame u can
have all ur logic
that checks the server and can instruct the visible frame
to refresh only
when it has to

You can have the JavaScript reload the page from your
servlet, i.e.
giving the servlet a new request. This is a common
solution.

Depends what your design goal is. A web server pushing
stuff onto
clients? Not my cup of tea, as you observed that's now
how the web
works. Clients requests, servlets (as their name
implies) and more
generally web servers (as their name also implies) serve.

Do Google search on IFRAME. They can be hidden easily in a div who's
style:visibility is set to hidden and comunication with the parent page, is
easy. (window.parent.methodName)

This will get routed to the doGet Method automatically.

RE: Having problems with stored PrintWriter.
I like the idea of this additional hidden frame.
Is there any pointers to where I could start to look at some code for hidden frames as
I have never had the pleasure to create them?
I suppose they would need to be able to communicate with each other aswell. must be
able i suppose.
Ok Ill go have a look at this. Cheeers for all your prompt help.
Del.
Since you guys dealt with this with such ease im stuck on another topic. last one
honestly.
On another hand im trying to call the servlet.
Im using this code
1 URL myUrl = new
URL("http://localhost:8080/servlets-examples/servlet/lbp.LBPServlet?ReceivedEvent=tester2";);
2 HttpURLConnection urlConnection = (HttpURLConnection)myUrl.openConnection();
Will this code get to the doget() method of my servlet or do i have to include
something additional to get into the servlet doget(). or dopost()?
Using this for event stimulus but doesnt seem to be working just now.

very true, if u try to make the browser hang on for too long then
eventually something will timeout (either on the client side or server

so as many here have suggested the best way is to refresh with javascript

but ... an even nicer solution is to create a hidden frame that has ur

that checks the server and can instruct the visible frame to refresh only

Eventually, something will time out. The browser, the server, your
firewall, many things can and will terminate the connection.

Re: Having problems with stored PrintWriter.
HTTP is a stateless environment.
You have no way of hanging on to the browser connection from the server.
Usually, if a user has to wait more than a few seconds for a response from
the server you would forward them to a page that refreshes itself every n
seconds via a META-REFRESH tag. Each time it refreshes, it checks the status
on the server.

RE: Having problems with stored PrintWriter.
Im trying to create a servlet that is able to push back to the browser rather than
just operate a a pull mechanism.
To create this, there is a piece of javascript embedded within the html outputted to
the browser, so when additional javascript code is written in at a later stage calling
that function, that user can be notified of events he is registered to.
Perhaps not the way servlets were made to work but anyway!
Unless you are able to come up with a better solution?
How do i stop the response from ending then? I have left the html open at the end so
no /html code and I have not closed the output to the browser.

Using jdk... message box
Hello, I am trying to use the installer for tomcat 4.1.12 for windows from another windows program. It works well in silent mode, but the only thing is that I get that message box that says that Tomcat will use 'jdk that was found in...', which seems to be the point where the installer stalls until I click ok. This is a bit annoying, do you know any method that I can get rid of that message box? Thanks. EC
REPOST: /devices/pseudo/mm@0:null
While using Tomcat, I have often encountered a problem (a java.net.SocketException) with "Too many open files". I understand that to combat this, I need to up the limit on file descriptors in my Solaris 8 system (ulimit command). The system went from 256 -> 1024 descriptors, but I still get the error, and in listing the open files, I will see "/devices/pseudo/[EMAIL PROTECTED]:null" as being used by my Tomcat process - over and over and over. I take it the Tomcat process is writing to "null"? Is it supposed to do that - or so much of it? Or does this indicate a problem somewhere?

RE: Having problems with stored PrintWriter.
Howdy,
Your design is flawed. The writer (whatever it's type is -- certainly
don't use a tomcat-specific type) is invalid after the response is done.
Don't store it, don't try to reuse it. What happens in practice is that
the server closes the underlying writer when the response is sent to the
browser and that's why you're getting the NPE.
What are you trying to do by saving the writer?

general security question about public / private keys
Is it possible to configure tomcat to use public / private key pairs that implement the java.security API for authentication a la ssh? I assume it is but haven't found out how yet. I'm using SSL at the moment but I need to implement a higher security environment in the same shape and form as ssh essentially. Just using public & private keys. Does this require an applet for the browsers? I'm currently ploughing through what I can find on the web and haven't got that far yet.
