Re: MOD_JK2 Error (shm.fil 13 Permission Denied)
Just put touch and chown shm.file in Apache control script (either apachectl or /etc/init.d/apache), and if you want in catalina.sh too At 16:11 18.07.2003 -0700, you wrote: My Apache HTTPD and Tomcat installation cosists for following version: 1.

problem with auto-generating mod_jk
Hi all. I use Apache2 <-> mod_jk <-> mod_jk Been a while since I had to auto-generate mod_jk. I have some new virtual hosts which I inserted into server.xml. I copied server.xml to the Apache server, started and stopped Tomcat and got a new .../conf/auto/mod_jk.conf It has all the new virtual hosts, but it doesn't have definitions for , the LoadModule and AddModule and the entries for the workers.properties. In other words, incomplete. I can cut and past the virtual hosts from the new mod_jk.conf to the old one, but that's hardly the point. What have I done wrong ??? Maybe should just add them manually to the old copy ??? TIA :( - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: How to clean objects in user's session
Older versions of tomcat have their Enumeration from
session.getAttributeNames() backed by an Iterator. So if a change is made you
get the ConcurrentModificationException. I know tomcat 5 does not have this
problem but I don't know about tomcat4. Since your using 4.1.24 - I am
guessing the change was not backported.
The easiest solution is to call invalidate - but this also usually logs the
user out too so it may not be acceptable. Once a session is invalidated - it
can't be used anymore for getting and setting stuff.
The alternative is clone/copy the Enumeration (probably the hard way by an
extra iteration) - then iterate through the copied version. The copied
version has no relation to the list so you can clear its atributes without
the exception.

Hello,
Our application is divided into multiple vertical views (ie, multiple
company). User can work in only one vertical slice at a time (ie, abc
company). Currently users have to logout and login again to change the
vertical. There is a business requirement to provide ability to switch
verticals without the need to logout and relogin. Here are my options.
1) invalidate the session object and create a new session. I am not sure
if this is possible with logout and relogin routine. We are using our own
authentication.
2) remove vertical specific objects from user's session. This option
seems to be less intrusive on users. However, I am not able to remove
objects Here is the test code
if((userPreference.getCurrentCompanyId() > 0) &&
userPreference.getCurrentCompanyId() != companyId){
Enumeration sessionAttributes = session.getAttributeNames();
while(sessionAttributes.hasMoreElements()) {
String name = (String) sessionAttributes.nextElement();
if ((name.compareTo("userSession") != 0) && //exclude vertical
independent objects
(name.compareTo("style") != 0) &&
(name.compareTo("moduleID") != 0) &&
(name.compareTo("listNavigatorMap") != 0))
logger.debug ("Name : " + name);
session.removeAttribute(name);
}
}
}
I am getting ConcurrentModificationException, detials are in attached file.
Can any one point out what am I doing wrong or let me know if there are
better ways to get to goal.

So i added the following lines to server.xml
I restart tomcat and the same location now gives me a 404 error
I suppose that a wrapped class cannot be a normal servlet in webapps space, but rather
a class in a
separate package, but i don't know if i'm right, and how to add classes visible to web
application in a
"clean" way and then wich parameters are correct in web.xml for that wrapped class.
I beg pardon for my poor english :)

Re: Tomcat Standalone with Jboss
Harsh, As I have said before, download and install the JBoss-Tomcat bundle and run it on a certain port. Then you can install the Tomcat standalone on another port. There is no conflict as long as they are on different ports. JBoss-Tomcat bundle does not use CATALINA_HOME, so you can keep that for your standalone Tomcat. Currently, I have applications running on my JBoss-Tomcat bundle and applications running on my Tomcat standalone, all on the same computer, and I don't have any problem whatsoever. Oh, by the way, my computer has a 2GHz P4 processor with 1G memory though. But there should be no problem with a lesser computer. Later on when you want to move to another computer, all you have to do is to move the JSPs, servlets, beans, etc to the new webapps location on the new computer. It is very easy.

Loosing DBCP object - how to solve it?
Hi guys, i have made a bean which creates a Data Base Connection Pool instance once, so that others systems components can use it. This beans is instanced when the Controller Servlet's init method runs. In other words, just one time this bean is instanced! Whenever i wanna get a connection object, i just call the bean's connection method, without creating new instances. However, i am getting the following errror, in which probably, the garbage collector is killing this object instance. BeanTip error - java.sql.SQLException: Timeout waiting for idle object I guess i could use a Singleton to deal with this situation, but i dont know how to! Could anybody help me, please.

Re: Adherence to DTD issue
Actually, all declarations must come before any declarations in the 2.2 DTD as well. It's just that Tomcat 3.2.x didn't enforce this. Tomcat 3.3.x does enforce it by default, but you can turn it off (for backwards compatibility reasons).

Jasper - including unbalanced jsp fragment
I would like to include static content from one file (call it header.inc) as part of the jsp text of another (mypage.jsp). Specifically, header.inc is supposed to include common html, head, and body content, following which mypage.jsp will contain page-specific content. So header.inc contains Common title and mypage.jsp starts with <%@ include file="header.inc" %> and goes on with the body content, ending with closing tags for body and html. This fails in jasper with an unterminated tag error at the end of header.inc. Of course, there are unterminated tags there (html and body), but that is intentional; they're terminated in the text of the full mypage.jsp, post-inclusion. I had thought that the inclusion was done first, before page parsing. Am I missing something? Surely I can't be the only person who wants to include unbalanced page fragments, right? Also, would/can this work for the dynamic inclusion techniques (c:import, jsp:include)? I may need those for other purposes, and my initial experiments ran into similar complaints about unterminated tags.
RE: How to clean objects in user's session
Thanks Tim, your suggestion works. Here is the changed code
Enumeration sessionAttributes = session.getAttributeNames();
ArrayList list = new ArrayList();
while(sessionAttributes.hasMoreElements()) {
String name = (String) sessionAttributes.nextElement();
if ((name.compareTo("userSession") != 0) &&
(name.compareTo("style") != 0) &&
(name.compareTo("moduleID") != 0) &&
(name.compareTo("listNavigatorMap") != 0))
list.add(name);
}
}
Iterator iList = list.iterator();
while(iList.hasNext()) {
session.removeAttribute((String) iList.next());
}

Older versions of tomcat have their Enumeration from
session.getAttributeNames() backed by an Iterator. So if a change is made
you
get the ConcurrentModificationException. I know tomcat 5 does not have this
problem but I don't know about tomcat4. Since your using 4.1.24 - I am
guessing the change was not backported.
The easiest solution is to call invalidate - but this also usually logs the
user out too so it may not be acceptable. Once a session is invalidated - it
can't be used anymore for getting and setting stuff.
The alternative is clone/copy the Enumeration (probably the hard way by an
extra iteration) - then iterate through the copied version. The copied
version has no relation to the list so you can clear its atributes without
the exception.

RE: Jasper - including unbalanced jsp fragment
A quick clarification -- this actually only causes problems on server-side taglib items, like Struts html taglib. So the problem occurs when I have in Header.inc but the close tag is elsewhere. I would think that Jasper would be combining the text pieces into one file before the taglib ever got to see the content, but that's apparently not the case. Can someone please explain this? -Original Message- From: Craig Berry Sent: Saturday, July 19, 2003 6:07 PM To: [EMAIL PROTECTED] Subject: Jasper - including unbalanced jsp fragment I would like to include static content from one file (call it header.inc) as part of the jsp text of another (mypage.jsp).

Recycling Tomcat
Hi! We are running Tomcat 4.1.24 on a Mandrake 9.1 Linux box. Occasionally we need to recycle Tomcat and the only way the administrator has found which works is to delete the lock file for Tomcat and then start Tomcat. I have to believe that there is a more elegant way to do it. I would also love to be able to recycle Tomcat remotely. I am remote from the server but have access to it from SSH, which gives me a secure command line to the server. Can anyone help with suggestions for either problem?

Jasper, Java, and X11 Dependencies
Hello, I'm having a problem where I log into a server w/telnet, and run JBoss (w/embedded tomcat). The server fails in jasper with X11 auth problem. I have a workaround: use ssh -X to handle X. If I use ssh -X instead of telnet, everything works fine. But because I can't explain why there is any X11 dependency for our server-side app, my boss deems this fix a "hack", and requires me to find a "real solution". The error is: Can't connect to X11 window server ... Why is there any X11 dependency on a server-side app? We have no servlets or anything like that. We are using apache struts. Precisely: My login page comes up (a JSP page) This page forwards to my first app page, which causes the X11 error. Figuring maybe something on this page was too complex (graphical, or whatever), I replaced it with another JSP page containing "Hello world" and nothing else. No dice... same X11 problem. I've tried building a new Linux server w/o any X11 installed on the box at all. This time I get even stranger errors: 00:12:49,053 ERROR [Engine] ApplicationDispatcher[/codatest] Servlet.service() for servlet jsp threw exception org.apache.jasper.JasperException: /opt/java/jre/lib/i386/libfontmanager.so: libstdc++-libc6.1-1.so.2: cannot open shared object file: No such file or directory at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:254) [clip] When I created a symlink to fix this I got my old X11 error back again! It seems something is still trying to use graphics. Is there a way to handle this situation or is using ssh -X my only option? Any explanation of this situation would be most appreciated. Thanks!

Re: Jasper, Java, and X11 Dependencies
Tomcat out-of-the-box has absolutely zero X11 dependencies. It must be something in your webapp. There are two ways to deal with this: 1) If you are using a 1.4.x JVM, you could try running it as 'headless'. 2) Install Xvfb, to provide a virtual X11 server.
