Help. Absolutely stuck. Tomcat cannot find my bean classes no matter what
when called from jsp pages. From within servlets no problem.
Here is the jsp
---
%@ include file=pub_hdr.html %
jsp:usebean id=FormBean class=beans.FormBean scope=request /
form
input type=text name=userName value=% =FormBean.getUserName() %
%= FormBean.getErrorMsg(userName) %
/form
%@ include file=pub_ftr.html %
Here is the bean
package beans;
import java.util.*;
import java.io.Serializable;
public class FormBean implements Serializable {
public String userName;
public FormBean() {}
public String getUserName() {
return this.userName;
}
public void setUserName(String uname) {
this.userName = uname;
}
}
NO MATTER WHAT, as soon as I access the jsp page. This error comes up.
Generated servlet error: C:\jwsdp-1_0\work\Standard
Engine\localhost\messagesmith\en\users$jsp.java:126: Undefined variable or
class name: FormBean out.print( FormBean.getUserName() );
It certainly seems that TC cannot find the FormBean class which lives here:
C:\jwsdp-1_0\webapps\project\WEB-INF\classes\beans.
I've changed that scope attribute to application or page, but it doesn't
change.
With TC3.x I had to do some configuration in the conf/server.xml file, but
this doesn't seem necessary w/ TC4. All the same I've adding the following
context to the server.xml, but it doesn't help.
Context path=/project
docBase=webapps/project
debug=0
reloadable=true /
Anyone have any ideas? It is killing me. Again, I can instantiate the
FormBean class from within servlets, but not from JSP.

Re: Cannot use bean from jsp, but servlet ok. I'm dying!
You could try replacing the usebean tag with a scriptlet and see what that does... % FormBean Bean=new FormBean(); % You would also need an import tag before this to import your package. I forget that syntax but you can look it up. Another suggestion... use the jspc compiler to generate an actual java source file from the jsp, then read that source. hth eric edahnke@earthli To: Tomcat Users List [EMAIL PROTECTED] nk.net cc: Subject: Re: Cannot use bean from jsp, but servlet ok.

Not to provoke you further : ) but I thought Linux didn't have threads, and that's why they show up as processes - they are processes. However I think it was also the case that the memory used is shared, so if you show twelve java processes using 64MB apiece, it's really only 64MB being used.

Re: R: HELP! iSaSiLk 3.04 and Tomcat4
Sorry, I'm the one who sent you down this trail, but am at a loss for
ideas. don't recall having any such problems.
You might scan the reference guide, it's extremely detailed:
http://java.sun.com/j2se/1.4/docs/guide/security/jsse/JSSERefGuide.html
This mentions some of the stuff about setting system properties to make
HttpsURLConnection happy and so on...
There's also a section in there where you can turn on debugging and get
more info from JSSE about what it's doing:

Thanks a lot for your reply
I followed your suggestions and I used JSSE integrated in JDK1.4anyway
now I have a problem with it
After installing JDK 1.4 I wrote the following Java code to open HTTPS
connections:
URL myurl = new URL(https://jcewww.iaik.at/;);
HttpsURLConnection con = (HttpsURLConnection)myurl.openConnection();
InputStream ins = con.getInputStream();
InputStreamReader isr=new InputStreamReader(ins);
BufferedReader in =new BufferedReader(isr);
String inputLine;
while ((inputLine = in.readLine()) != null)
System.out.println(inputLine);
in.close();
At statement InputStream ins = con.getInputStream(); I receive this
exception:
javax.net.ssl.SSLHandshakeException: Could not find trusted certificate
If as URL I insert www.verisign.com all works correctly. I tried to set a
my
HostNameVerifier class for the HttpsURLConnection object. It is something
like this:
class MyVerif implements HostnameVerifier
{
public boolean verify(String hostname, SSLSession session)
{
return true;
}
}
The verify process returns always true in any caseI thought that this
trick let me
to avoid this type of error but I was wrong, in fact inserting the URL
https://jcewww.iaik.at/;
I receive the same error :-(
I tried to install IAIK provider and iSaSiLK APIs and all works fine with
url https://jcewww.iaik.at/;
too!! How come? It seems that IAIK provider doesn't check if there is a
trusted certificate available
How can I avoid the javax.net.ssl.SSLHandshakeException using only JDK
1.4??
I hope you or someone else can help me

I remember using issasilk a couple years ago... I barely recall there being
some system property that you're supposed to set so that it uses your
particular SSL implementation. I think somehow that's not getting set or
somebody's resetting it after you... hth.
However the thing is, you can get a great SSL implementation straight from
sun nowadays:http://java.sun.com/products/jsse/. The only reason I ever
used issasilk was because my coworkers were adamantly opposed to upgrading
to jdk 1.2 (fud), which was required for Sun's SSL. JSSE was better behaved
(issasilk would always throw an exception at the end of the stream or
something) and of course free. JSSE is now included in JDK 1.4, and is I
think included in some of the tomcat distributions.
But hats off to those Austrian folks for making java SSL inexpensive while
the competition was gouging people for upwards of $20K
(note - It's probably not necessary to post to both tomcat-dev and users
for this sort of thing)

Re: Tomcat 4.1/4.0 manager application

First, follow the directions in Manager App HOW-TO included with the tomcat documentation. Once this is done, you can use the manager app reload function to reload the web app. This also refreshes any newly compiled classes (e.g. javabeans) that you may have included in the JSPs. To use the reload, do the following: http://IP Address/manager/reload?path=web app You can also use the manager to deploy new web apps, un-deploy web apps, start/stop web apps.

Just my two cents, but I never have developers work on the same server instance.

i deleted the message, but somebody was asking about how to specify heap size in the params to tomcat, and i said you could probably pass such as a param to startup.bat/startup.sh - not true. command line arguments are passed through to the actual tomcat invocation, but *after* the classname, not before it, so the vm will ignore them. Not a bug, it's so you can tell Catalina where to get its config file and so on. So the only way to specify options to the VM is via the CATALINA_OPTS env variable. My mistake.

Re: Heap Size for Tomcat
Well, yeah except he wants to get more memory... and wouldn't setting the XXXOPTS variable set the heap size not just for startup but also shutdown? In other words, this way you could get tomcat to start with 512mb of heap, but if you call shutdown.bat/shutdown.sh, the shutdown vm grabs its own 512mb heap... I dunno... troy Phillip Morelock subscriptions@phillipmo To: Tomcat Users List [EMAIL PROTECTED] relock.com cc: Subject: Re: Heap Size for Tomcat 05/16/2002 06:19 PM Please respond to Tomcat Users List The official way to do it is to set a TOMCAT_OPTS or CATALINA_OPTS variable with the string that you would normally feed the VM.

jsp's do not compile
I cannot get tomcat to recompile jsp's after I change them. I have tried the 4.1 alpha nightly build as well as 4.0.3. I know this is supposed to work... Is there some special parameter I should be configuring or something? I've searched the docs.

Re: jsp's do not compile
Thanks for the suggestion, but even killing the explorer process doesn't help. On 4.1 I was able to get the jsp to recompile by telling the manager to reload (actually used the new ant reload taskdef in 4.1). I would try to do this on 4.0.3, but for some reason the admin/manager whatever it is thing isn't available... isn't it supposed to be a link on the default tomcat home page for the server (i.e. http://localhost:8080/index.jsp)?

Re: jsp's do not compile
My own understanding is that for servlets other java classes, yes, you need to use the manager application to reload them, and I can get that to work on 4.1; but I thought that JSP's are supposed to automatically recompile. Am I wrong? Can somebody confirm? I've noticed a lot of back-and-forth-ambiguity about reload/recompile on this list...

Re: jsp's do not compile
Wait, wait, wait, wait, I am stupid. Sorry. I got confused between my multiple installations. JSP's reload quite nicely now on 4.0.3. 4.1 has a problem though... will feed that to bugzilla. But I can't get 4.0.3's manager to come up, don't know what I'm doing wrong.

Re: Tomcat, mod_jk and Apache...again!
Personally, I would like to have the choice to put my jsp/html/images etc. somewhere besides the tomcat installation directory. It's just one less hassle to deal with when you're upgrading tomcat. Tore Skogly tore.skogly@c2i To: Tomcat Users List [EMAIL PROTECTED] .netcc: Subject: Re: Tomcat, mod_jk and Apache...again! 05/10/2002 05:48 PM Please respond to Tomcat Users List Thanks for your help. It made things clearer to me. I am using ldap to allow only some users to access webpages in different directories. Therefore it would be easier for me to keep the jsp pages with my html stuff. I guess I could try to edit the server.xml file and set /var/www/html as my webapp directory, but I might have to settle with what you suggests - put them in the $TOMCAT_HOME/webapps directory. Thanks again for your assistance! ToreS - Original Message - From: Zachary Kuhn [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED] Sent: Friday, May 10, 2002 8:36 PM Subject: RE: Tomcat, mod_jk and Apache...again! Tore, In order to help, please be more descriptive about your access restrictions, and the way you have set up your directories. Based on the things you have said so far, this may be your problem: Tomcat looks in its webapp directory for webapps to deploy. Even a single jsp page constitutes a webapp(albeit a simple one). I think you are missing this fundamental point of tomcat. Tomcat needs to look for your jsp pages, then compile them, and put them in a working directory where they can be served. It has no idea that there is such a place as /var/www/html, only a $TOMCAT_HOME/webapps directory. The only way you could let it know about /var/www/html would be to modify the xml config file. But it is much easier to just put your jsp pages in $TOMCAT_HOME/webapps, the way the system was designed. Sorry for any errors, but that is my understanding of it.

Greetings: Am using a the latest build of tomcat 4.0 on Win2K. Just started working with tomcat today, pardon my lack of familiarity.
