Re: determining which jdk tomcat is using
How are you starting Tomcat? Are you on a windows machine? The environment settings set in the System properties on NT/2000/XP don't affect already running cmd.exe windows. If you REALLY want control over a specific Tomcat instance, modify your catalina.bat/catalina.sh file to define a specific JAVA_HOME variable (right under the header comment block).

Re: determining which jdk tomcat is using
Are you setting user environment variables or system environment variables when you change JAVA_HOME? I think the NT service will use the system environment, since it's not necessarily associated with a user. Anyway, I would recommend against using the service actually.

Re: JDBCRealm w/ Apache, How to???
The real question is how big of a performance problem is the DefaultServlet in Tomcat compared to Apache. Are you REALLY losing THAT much performance by letting the DefaultServlet serve those static files? Is it necessary? - Original Message - From: Mete Kural [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED] Sent: Monday, March 24, 2003 3:20 AM Subject: JDBCRealm w/ Apache, How to??? Hi, I am perplexed at this interesting problem. We want to use JDBCRealm to authenticate users in Tomcat, but yet we want to serve static stuff via Apache to improve performance (we have a lot of static material behind authentication). If we set up Tomcat as a worker for Apache using the JK2 connector, I don't see how requests for static files are going to be authenticated via JDBCRealm, since Tomcat doesn't even know about these static requests in the first place due to the fact that Apache handles them right away without dispatching them to Tomcat. I'm thinking that if we could somehow set up Apache to be a worker for Tomcat, and Tomcat received all requests and dispatched those that are static to Apache, then all requests would be authenticated via JDBCRealm. But I don't know how to do that neither if this is possible at all. Do you have any ideas on how to authenticate every request with JDBCRealm yet serve only static stuff with Apache.

Re: Problem with Bookmarking a Login Page
The way I always do it is I create a User (with email, fullName, etc.) class
which is mapped into my database to the same tables I instruct Tomcat to use
for a JdbcRealm. Then, I set up a filter which makes sure that a User
object exists when there is a user principal. You can use the
request.getUserPrincipal().getName() to find out the username of the logged
in user. In your filter, you do something like...
User user = ( User )request.getSession().getAttribute( user );
if( user == null request.getUserPrincipal() != null )
{
user = UserDao.getUserByName( request.getUserPrincipal().getName() );
request.setAttribute( user, user );
}
Hope this helps!

Subject: Problem with Bookmarking a Login Page
Does anyone know of a Struts work around for the problem with Tomact
in bookmarking the login page for container managed security?
There was a brief thread on this issue about a month ago
[http://www.mail-archive.com/[EMAIL PROTECTED]/msg59734.html]
There is a SourceForge project called SecurityFilter that can be used
to replace Tomcat's container managed security, but it would be nice
to be able to work with Tomcat.
Has anyone tried to call j_security_check directly from an Action
class? Once you can authenticate a user you would be able to get the
roles for that user.
Is there a way to set up a JDBC Realm purely in Struts? I did not see
any information on this in a quick scan of the documentation.
Hopefully, the good people working on Tomcat see this as a bug that
needs to be fixed.
Quote from a recent thread in the Tomcat news group: I wish that
there was a legitimate configuration change to enable you to bookmark
a login.jsp page--such as a j_success_url parameter which instructs
Tomcat where to send users if not doing an automated login process.
Another user stated, ...I simply just can't believe that there are
Tomcat instances out there in a live production environment with
configured realms that suffer from this problem. Surely there must be
something

Re: Help with Servlets
Yes, you do need to provide a servlet mapping for each of your servlets you
wish to run, unless you want to run the invoker servlet (not recommended).
Usually you map a different url pattern for each servlet in your webapp.
This can be somewhat tedious, so I use XDoclet to generate my web.xml file
for me! But, for simple projects, this is not necessary.

Firstly, your web.xml looks kinda screwed: You have nothing mapped

You need to map your web application to it's implementation. It's not

will also need something like
!-- Map requests to servlet --
servlet-mapping

Re: custom JDBCRealm
You don't need to implement a custom realm for this. You can use a servlet
filter. The userid of the currently logged in user can be accessed via
request.getUserPrincipal().getName(). You can use this information to
lookup the other user data in the database and place it in the session (if
it doesn't already exist).

Re: tomcat servlet invoker
Yes, you must create a servlet mapping for each servlet. You could use XDoclet to generate your web.xml file, which can alleviate some of the burden and maintenance overhead. - Original Message - From: Boon Seong [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED] Sent: Sunday, March 23, 2003 6:59 AM Subject: Re: tomcat servlet invoker What will be used to invoke the servlet then ?

JSP bodycontent?
Does Tomcat support the JSP body content for a BodyTag? In my doAfterBody
method (inherited from BodyTagSupport), I return EVAL_BODY_TAG. I have some
debug statements in my code, so I can see that the doAfterBody method is
called multiple times, but I'm not seeing the html that should be generated
by my JSP code within the tag's body. Can somebody help me?
Here's my Java code...
package ws.carman.taglib;
import javax.servlet.jsp.tagext.BodyTagSupport;
import java.util.Iterator;
import java.util.Collection;
import javax.servlet.ServletRequest;
public class IterateTag extends BodyTagSupport
{
private String m_CollectionName;
private String m_ElementName;
private Iterator m_Iterator;
public final void setCollectionName( final String newCollectionName )
{
m_CollectionName = newCollectionName;
}
public final void setElementName( final String newElementName )
{
m_ElementName = newElementName;
}
public final int doStartTag()
{
final ServletRequest request = pageContext.getRequest();
final Collection coll = ( Collection )request.getAttribute(
m_CollectionName );
m_Iterator = coll.iterator();
return doNext();
}
public final int doAfterBody()
{
System.out.println( "Inside doAfterBody!" );
return doNext();
}
private final int doNext()
{
if( m_Iterator.hasNext() )
{
pageContext.getRequest().setAttribute( m_ElementName,
m_Iterator.next() );
System.out.println( "Current element is " +
pageContext.getRequest().getAttribute( m_ElementName ) );
return EVAL_BODY_TAG;
}
else
{
return SKIP_BODY;
}
}
public void release()
{
m_ElementName = null;
m_CollectionName = null;
m_Iterator = null;
}
}

RE: JSP bodycontent?
I copied this out of the documentation of the BodyTagSupport class'
doAfterBody method...
"Actions after some body has been evaluated. Not invoked in empty tags or in
tags returning SKIP_BODY in doStartTag() This method is invoked after every
body evaluation. The pair "BODY -- doAfterBody()" is invoked initially if
doStartTag() returned EVAL_BODY_TAG, and it is repeated as long as the
doAfterBody() evaluation returns EVAL_BODY_TAG"
So, it seems that the pair "BODY -- doAfterBody()" will be invoked so long
as doAfterBody returns EVAL_BODY_TAG, and in my example, it does execute the
correct number of times (5 in my case, one for each String object in the
collection). The only issue is that it's not actually executing the JSP
code inside the tag. It's iterating correctly, but not actually doing the
work inside the body of the tag. Has anyone else seen this?

You must return EVAL_BODY_TAG in your doStartTag() method, not
doAfterBody(). Have a look at the jakarta-taglibs project for some nice
examples, in particular
/utility/src/org/apache/taglibs/utility/basic/IncludeTag.java
As an aside, I noticed that JRun does not comply with the spec and call
setBodyContent on empty tags like util:include url="foo.html"/. You have
to trick it by saying util:include url="foo.html"/util:include. This
means that some jakarta-taglibs taglibs won't work under JRun. This isn't
fixed in SP1, so watch out for it if you ever have to port to JRun.
