Re: JSP CUSTOM TAGS
Peter --
All that you need to do is get your PageContext, then call getSession()
on that. Then you've got your session and can retrieve stuff from it.
Here's some pseudo-code to explain:
private PageContext pageContext;
public void setPageContext(PageContext pageContext) {
this.pageContext = pageContext;
}
public int doStartTag() throws JspException {
HttpSession session = pageContext.getSession();
Object objTarget = session.getAttribute(target);
return SKIP_BODY;
}
public void release() {
pageContext = null;
}
Hope that helps...

Re: (EXPERTS ONLY) Bean Creation in Dispatch Servlet
Hi Leon --
I had something similar happen, and it occours when I recompile the
bean and then try to access it without restarting Tomcat.
My *guess* is that classes that are reloaded (when they have been
loaded once then recompiled) have a different classloader.
Anyhow, restarting Tomcat has always resolved that problem for me.
Hope that helps.

Hello All,
Let me preface this email by saying that I only put 'EXPERTS ONLY' so
you hot shot programmers would actually read this email. If you are
reading this, it worked!
I have an odd problem that I was hoping someone could help with.
I have a servlet that all jsps in the system are dispatched from. I
create a bean in this servlet and add it to the request object like
so...
com.blah.blah.MyBean abean = (com.blah.blah.MyBean)
Beans.instantiate(this.getClass().getClassLoader(),com.blah.blah.MyBean);
...
request.setAttribute(thename, abean);
I have also tried this to create the bean
com.blah.blah.MyBean abean = new com.blah.blah.MyBean();
and also tried to place the object in the request like so
pageContext.setAttribute(thename, abean,
PageContext.REQUEST_SCOPE);
Anywho, I then have the following in my jsp page...
jsp:useBean id=thename scope=request
class=com.blah.blah.MyBean /
I get a java.lang.ClassCastException from the jsp. So, I decided to
do a little error hunting in a jsp using the following code...
%try{
System.out.println(request.getAttribute(thename) == null);
System.out.println(request.getAttribute(thename) instanceof
com.blah.blah.MyBean);
System.out.println(request.getAttribute(thename).getClass().getName());
System.out.println(zedak.docworx.jspsupport.beans.BrandBean)request.getAttribute(thename));
}catch (ClassCastException e){
System.out.println(CLASS CAST EXCEPTION!);
}
%
The results of the code is as follows:
false
false
com.blah.blah.MyBean
CLASS CAST EXCEPTION!
So, the attribute is present in the request object, it is not an
instance of 'com.blah.blah.MyBean'; but the object's class name is
'com.blah.blah.MyBean'. Does anyone have an idea what is going on?
How can the object's class name be 'com.blah.blah.MyBean' but not be
able to cast to 'com.blah.blah.MyBean'?
Thanks in advance!

Re: how to create a war file manually
Use jar. Assuming that you have your dir structure set up correctly, all you have to do is jar them up, specify whatever.war as the file name, and there you have it. Anne Jianlin Chang wrote: How can I create a war file manually? I know I can follow Developing Applications With Tomcat and use build.xml, but that seems more complicated, is there a simple way where I can just pack everything needed (jsp, html, classed) into a war file using a single command?

Specification Question RE: Cookies
Hi all -- I have a question regarding cookie expiriation. I am trying to expire a cookie immediately, and the Servlet Specification (and javadoc) states that: Cookie's public void setMaxAge(int expiry) Sets the maximum age of the cookie in seconds. A positive value indicates that the cookie will expire after that many seconds have passed. Note that the value is the maximum age when the cookie will expire, not the cookies current age. A negative value means that the cookie is not stored persistently and will be deleted when the Web browser exits. A zero value causes the cookie to be deleted. My guess, based on this is that cookie.setMaxAge(0) should expire the cookie immediately, but it seems that with Tomcat the missing step to re-add the cookie to the response, at which point it is actually deleted. What I'm wondering is, is this a required step? I've noticed that Oracle implements this differently, deleting the cookie immediately when the MaxAge is set to 0. Can anyone who is familiar with the specification enlighten me? Thanks, Anne
Re: Please urgent : Why french accentual chara cters (like à è) not display
Are you using the actual characters or the HTML standins for special characthers? If you are just typing the characters, the browser may not be able to display them as is. Try using the HTML special characters. The special characters begin with an then the ASCII Number for the item, then a semicolon, for example 151; for a dash. There are lots of HTML books with charts of those. There are also some easy-to-remember shortcuts like agrave; egrave; aacute; eacute; acirc; that might help. Hope that helps.

Re: OAS and jserv
Peter -- Yes, you can integrate Tomcat with OAS (at least according to the documentation I've read). I was not able to find any evidence that it was supported, however. Given that, and the horrible performance we were experiencing with OAS our project decided to give up on OAS altogether (or until 9iAS looks like a reasonable option), so luckily I didn't have to go down that path. I can dig up some documentation though, if it would be helpful. Anne Peter Smith wrote: Can Oracle Application Server/Apache be integrated with Tomcat (presumably using mod_jk) instead of the JServ it ships with? Anyone done it? I'm stuck using Oracle Application Server and I wish to deploy Java-based apps using Tomcat instead of the shipped JServ engine. Someone has previously asked the list and I didn't see any reponses. From reading bits and pieces I gather that it may be possible, but it might be hairy and it's probably not supported. I may have the option of upgrading to Oracle9iAS, which offers the new Oracle Enterprise Java Engine which looks like it does what Tomcat can. Comments? --Peter-- __ Do You Yahoo!? Yahoo!

(localhost:8080/) Do not add any contexts yet. First you want to get the isapi_redirect.dll installed so that you can call the examples directly without referencing the port. If you haven't downloaded this yet get the binary from the apache site. There are several steps to follow in the IIS how to instructions. Again follow them explicitly. You will need to register the isapi _redirect.dll with IIs, modify your registry (be very careful!!), create a directory to place the isapi redirect into, and modify your workers properties file. (tomcat/conf/workersproperties) I am doing this by memory so follow your instructions carefully. Most people make their errors in the registry settings. Again it is so much easier if you print out the instructions. If you want to test some jsps or servlets that you have already made before you have the isapi working, place the jsps into the ROOT directory and call them with (localhost:8080/yourjspname.jsp). Servlets must be placed in the WEB_INF/classes directory and are referenced by (localhost:8080/servlet/yourservletname_noextention). Spend a little time getting familiar with the directories. All of your web apps go under the webapps/ROOT directory. You will know if isapi is working when you can drop the port reference and still get them. Sounds like you are getting there. Go one small step at a time, test your results, then proceed. By the time you install tomcat for the 3rd or 4th time it will only take 30 minutes. Print out all of the conf files. All your tomcat configuration is done through modifying them. They are well documented with comments. Tomcat adheres strictly to the Sun jsp/servlet APIs so those documents are worth getting familiar with as well.

Re: file upload servlet
Christoph --
You do need the trailing = after %
Here's why:
What you are trying to send from your HTML form is something like this:
form enctype="multipart/form-data" action="/servlets/servlet/Upload"
method="post"
input type="file" name="FileData" value="" size="52" maxlength="255"
input type="submit" value="Abschicken"
/form
The %= % is a jsp Expression, which means that the value of whatever
is in it will be converted to a String and then printed out. Since this
is done before the HTML is processed, what you get is something like in
the above example.
As you have it below, with % %, you are not ever actually including
the value of your encoded URL into your form.
It's just a scriptlet, which will actually encode your URL, but to no
avail, since it has no explicit String conversion or printout
capabilities and thus won't be a part of your form.
all the %= response.encodeURL("/path/to/Servlet") % is doing is
rewriting your URL to include session data if cookies are not enabled.
For a first shot at it, you might want to consider just building a set
of tags like I included above and making sure that works (make sure you
have cookies enabled, though!) After you have that working, it might be
a lot easier to get your session encoding working, conceptually.
What the leftover method="post" signals to me is that somewhere you are
closing the form tag before this part of it, i.e., that the browser
encounters a before it encounters method="post" and thus assumes that
the form tag has been completed and that method="post" is regular text
to be printed to the browser window.
Hope that helps,
Anne

Tomcat on Solaris
Hi All -- I'm trying to install Tomcat on Solaris 8 (sparc) and am running into problems. I'm running Tomcat 3.2.1, with java 1.2.2: java version "1.2.2" Solaris VM (build Solaris_JDK_1.2.2_06, native threads, sunwjit) I have tomcat installed and running happily (more or less) on an identical (or so I thought!) machine. First I tried installing from a newly downloaded .tar.gz and got the following exception: Exception in thread "main" java.lang.ExceptionInInitializerError: java.util.Mi ssingResourceException: Can't find resource for base name org.apache.tomcat.reso urces.LocalStrings, locale en at java.lang.Throwable.fillInStackTrace(Native Method) at java.lang.Throwable.init(Throwable.java:94) at java.lang.Exception.init(Exception.java:42) at java.lang.RuntimeException.init(RuntimeException.java:47) at java.util.MissingResourceException.init(MissingResourceException.java:54) at java.util.ResourceBundle.getBundle(Compiled Code) at java.util.ResourceBundle.getBundle(ResourceBundle.java:339) at org.apache.tomcat.util.StringManager.init(StringManager.java:115) at org.apache.tomcat.util.StringManager.getManager(StringManager.java:260) at Unloaded Method Given that, tried tarring up my working tomcat from the other solaris box and moving it over, and got the same exception. All of my environment settings between the two Solaris machines *should* be identical. In fact, the machine that does work was, two weeks ago, an exact copy of the one that is failing... Has anyone run into something similar before? If so, I'd be thrilled to hear a fix. Thanks, Anne [EMAIL PROTECTED]
