Matt, Your best bet is to read the security manager documentation provided as part of the SDK. It should be located in JAVA_HOME\docs\guide\security\permissions.html and JAVA_HOME\docs\guide\security\PolicyFiles.html I can't remember if these docs are part of the standard download or whether you need to download the separate docs package. Bear in mind that tomcat might need some of the permissions you are looking to restrict. The sample security policy file provided (TOMCAT_HOME\conf\catalina.policy) provides more details. One option would be to just restrict the deployed web applications rather than the entire tomcat installation. Again, see catalina.policy for more information.

method=post but doGet() called
Hi all!
I have a form (included below) where I set method=post, but for for a
specific action URL, it arrived in the doGet method instead of the doPost
method.
I have a seervlet-mapping that pics up _all_ resquests to the context:
url-pattern//url-pattern
The unexpected behaviour comes when there is nothing after the context in
the action URL:
http://localhost:8080/mycontext
This arrives in doGet.
Putting something after the context works:
http://localhost:8080/mycontext/stuff
This arrives in doPost.
Is this correct behaviour? I am using Opera as browser. Should this make a
difference?

Re: java.lang.OutOfMemoryError
How much information do you put in servlet sessions? How long do sessions last? How many active user sessions do you have at any given time? Do you start the VM up without providing -Xmx512m or something like that? If so, you are starting a VM with a maximum of 64meg of memory available to everything running within it. That includes the appserver itself plus any apps. It is easy to use more than this, especially if your load is high and/or you store lots of info in the sessions. Keep in mind that a little bit of data in the session can go a long way if you have lots of users. Less than 1meg per/user plus, let's say, 64 users with active sessions (not necessarily making concurrent requests) would easily use up the default memory maximum of the VM.

Deployment with the manager app (manifest question)
Dear Sir / Madam, I am testing the deployment of a webapp that needs some java extensions (jdbc connectors) which are not available on the server. I specified the optional packages and their versions in the MANIFEST.MF file included in the WAR file as I suppose one has to. Surprisingly, the manager app does not report any error when I deploy the war file... but, of course, the deployed application won't start because it does not have all the needed extensions. I am using tomcat version 5.0.19 and my MANIFEST file contents are as follows: Manifest-Version: 1.2 Name: CMECP/fo Class-Path: servlet-api.jar activation.jar mail.jar com.mysql.jdbc Extension-List: activation mail mysqljdbc servlet activation-Extension-Name: javax.activation activation-Specification-Version: 1.0 activation-Implementation-Version: 1.0.2 activation-Implementation-Vendor-Id: com.sun activation-Implementation-URL: http://java.sun.com/products/stdext/activation.jar mail-Extension-Name: javax.mail mail-Specification-Version: 1.3 mail-Implementation-Version: 1.3.1 mail-Implementation-Vendor-Id: com.sun mail-Implementation-URL: http://java.sun.com/products/stdext/mail.jar mysqljdbc-Extension-Name: com.mysql.jdbc mysqljdbc-Specification-Version: 3.0 mysqljdbc-Implementation-Version: 3.0.10 mysqljdbc-Implementation-Vendor-Id: com.mysql mysqljdbc-Implementation-URL: http://www.mysql.com/products/mysql-connector-java-3.0.10-stable- bin.jar servlet-Extension-Name: javax.servlet servlet-Specification-Version: 2.4 servlet-Implementation-Version: 2.4.public_draft servlet-Implementation-Vendor-Id: org.apache servlet-Implementation-URL: http://jakarta.apache.org/products/servlet-api.jar Do you detect any changes I might do to the MANIFEST.MF file so that Tomcat's manager stops it from being deployed?

RE: java.lang.OutOfMemoryError
I was having a similar problem with a similar configuration but was having to restart every day. For some reason the exact same JDK/tomcat install on my windows dev box performed just fine under stress testing and reclaimed memory just fine whereas my Linux production box had serious issues. I increased the memory from the default 64mb to 128mb on my linux server and now it is behaving just as the prod server does - its reclaiming memory in a similar healthy pattern. So, just try increasing the heap size to 128mb first and see if you're still having the same issue. It seems to work some magic. Cheers.

Tomcat Deployment question
Hi all, For a deployed WebApp with a applet and a servlet (I already generated a WAR in JBuilder), where should i put my servlet so that Tomcat knows where to find it? Current this is how my system is set up. Using JBuilder, I created a WebApplication where I direct the defaultroot folder to the location of my applet files. Then within my WebApplication, I created a servlet that the applet should communicate with. Then a WAR is generated when I build in JBuilder. I then deploy this WAR file into Tomcat5 using the TomcatManager. However, when I select the HTML file, I can see that my applet is running but it can't communicate with the servlet and I get a java error that saids filenotfound. So what is it that I'm doing wrong? Where should I put my servlet.java and servlet class so that Tomcat can find it? Thank you! Kay - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: method=post but doGet() called
When Tomcat sees a request for 'http://localhost:8080/mycontext' it sends
back a response to redirect to 'http://localhost:8080/mycontext/'. This is
so that relative links to things like images and stylesheets work correctly.
If the browser conformed to the HTTP/1.1 RFC, it would re-request the new
URL with a POST, but I don't know of any browsers that do this.

It is intended to ask the user for hostnames/IP-addresses for tomcat and a db-server, edit the context.xml to reflect the datasource, do some sql initialisation (so far, so good) and then (now that seems tricky) antomatically deploy the (local) war to a remote tomcat instance.

RE: thread deadlock problem
Hi Antonio, Are you absolutely sure of that? Could you please triple-check it? A System.out.println(something) at the *very* beginning of the doGet/doPost method would be enough. Yeah. I'm basing it on the timestamps in the log4j log messages (which I've never yet seen to be wrong). And I've verified it numerous times. Strange... Unlikely... but possible... Yeah, that's what I thought too. And you would not make your writer wait, so your process would be faster, wouldn't it? Yes, it would be faster (at least theoretically, although in practice blocking doesn't occur unless the pipe fills up...so by tuning the size of your pipe you should be able to come up with something that is just as fast, in XX% of the cases). The downside of writing the whole thing to memory is that in this small percentage of scenarios, the entire document gets written to memory first, and if its a report that is hundreds of pages long, its possible to run your server out of memory under load. So the piped approach (if I could get it to work), would be preferable, even if there's a slight hit on throughput. But if I can't, I can live with the in-memory version.

Possible thread crossing
Hi all, I've tried searching archives and bugzilla for this but have come up empty handed. I am running Tomcat 4.1.30 on RedHat 9. My java version is 1.4.2. One thing I have noticed is that there is only one java thread when I start tomcat. On a previous install there had been about 8. Here is the output of ps -ef relative to tomcat: tomcat 13074 1 0 Mar11 ?00:00:32 /usr/local/java/bin/java -Djava.endorsed.dirs=/usr/local/tomcat/common/endorsed -classpath /usr/local/java/lib/t Here is my problem: I have a jsp form that accepts user input which is then verified and sent off for processing. I have approximately 10 forms set up for 10 different clients. Each form has a specific serial number hard coded in it which gets passed to the java bean processing the data- this way we can easily identify which client the data is being processed for. What is happening is that information is getting crossed between clients and information for client A gets processed under client B's account. This only appears to be happening for 4 of the clients - which happen to be the ones processing the most data. Researching the problem shows that my app is sending the wrong serial number. The only thing I can narrow it down to is Tomcat/Java. Like I said the serial numbers are hard coded on the jsp pages. Everytime this jsp page is submitted it forms its own instance of my java bean which can be called one or more times. So I guess my question is - is it possible that somehow information from one thread is leaking to another thread? Thanks in advance. Denise Mangano Complus Data Innovations, Inc. 914-747-1200

Subject: Why can't tomcat find my bean classes?
I'm running jakarta-tomcat-5.0.18 on OSX.
I've got a trivial little JSP file:
jsp:useBean id=doubler class=DoublerBean scope=page
jsp:setProperty name=doubler property=in value=wugga/
/jsp:useBean
html
body
It looks like quot;jsp:getProperty name=doubler
property=out/quot;
/body
/html
and my DoublerBean.java file is pretty simple too:
public class DoublerBean
{
private String phrase;
public DoublerBean ()
{
// empty
}
public void setIn (String phrase)
{
this.phrase = phrase;
}
public String getOut ()
{
return (phrase + , + phrase);
}
}
When I run ant, I get a build/WEB-INF/classes/DoublerBean.class file,
but my jsp application can't seem to find the DoublerBean class. When
I reload my app through the manager and run it, I get:
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 1 in the jsp file: /foo.jsp

and a few more similar errors complaining that it can't resolve
DoublerBean. Other JSP pages I wrote were able to find their required
classes in the same location. What's different about finding bean

RE: Horrible memory leak in tomcat 5.0.19 (JMX bug?)
To your question: I don't know. Having a delay in the jsp (or servlet) isn't enough to enshure concurrent requests. You have to do something on the calling site to enforce this. If you just call lynx as in your example, lynx will wait until the response is there. So if you delay the jsp, you just delay the return of lynx. So you have either to run more than one instace of your script at the same time or to extend the scrip in a way that it runs several lynx instances at the same time. -Original Message- From: Joseph Shraibman [mailto:[EMAIL PROTECTED] Sent: Friday, March 19, 2004 7:21 PM To: Tomcat Users List Subject: Re: Horrible memory leak in tomcat 5.0.19 (JMX bug?)

redirecting ajp13 requests from tomcat to tomcat
Hi, I am running tomcat 4.1.24 on solaris - with an IIS 5 webserver using isapi_redirector2.dll. I have 2 instances of tomcat servlet engine running on different ports on solaris. I would like IIS to send all ajp13 servlet request to tomcat instance1. I would then like tomcat instance1 to forward certain requests (based on certain URL pattern) to tomcat instance2. I can see that I can do this via a servlet or the balancer webapp if I want to redirect http:, but does anyone know a way I can redirect ajp13? BTW - I do not want to reference both tomcat instances in the workers2.properties file on the IIS webserver - I just want tomcat instance1 to handle any redirecting required. I hope this question makes sense!

Re: http://localhost/ works but http://ip address/ doesn't
Hello Doug, Sitting at you windows box that is running TC you can open IE and access http://localhost but if you try to access http://yourMachinesIP it fails. Right From a command prompt ping localhost. Then ping the IP of your machine. Both return a response. I'm using the Linksys router BEFSR41 with port forwarding enabled for port 80. Notice that localhost resolves to 127.0.0.? Do an ipconfig /all from the command promrt. Confirm the IP of your machine. This shows 192.168.1.100 as the IP for my machine. Are you running ANY firewall software? Disable it on a temporary basis to test. Not sure how to cleanly disable the Linksys firewall protection. Then configure it to allow http port 80 traffic through. Port forwarding is enabled for port 80 (http). What else? I am not aware of any setting that binds tomcat to an IP like apache can. Although you can filter on an IP.

Is there something I need to do to server.xml to enable this to work?
