Fwd: org.apache.jasper.JasperException: Unable to compile class for JSP

2004-07-16 Thread Vladimer Shioshvili

I am trying to set up Tomcat 5.0.27 for my coworker. I mean we already 
installed jdk 1.4.2 and tomcat 5.0.27. Examples jsp pages work fine, but 
when trying to view the jsp pages in the application i put in (Mondrian) i 
get the org.apache.jasper.JasperException: Unable to compile class for JSP 
error. I installed tomcat 5.0.27 on my machine and the whole shebang works 
fine.

I am looking for leads...
Thanks in advance,

serving binary files

2004-03-01 Thread Vladimer Shioshvili


Does anyone have a suggestion on how to server binary files through tomcat? 
I am creating a binary file as a result of a request and would like to let 
the user download it. Just setting mime type and passing through as an 
attachment doesn't work as write methods of the writer seem to truncate 
upper bits of the data.

Any useful suggestion would be greatly appreciated.

Thanks,
Vlad

This is not specific to tomcat, it's basic servlet writing.  If you're
outputting binary data, don't use the writer obtained from
HttpServletResponse#getWriter.  Instead, use the output stream obtained
from HttpServletResponse#getOutputStream.  Then setting the mime type
will be sufficient.
Any useful suggestion would be greatly appreciated.

Re: Problem with spanish accents and the 'ñ' char

2003-12-22 Thread Vladimer Shioshvili
Leandro,

that sounds like an encoding issue either when retrieving the data from the 
DB, or when displaying in the jsp. In the jsp page try to use % page 
Content-Type=text/html; charset=iso-8859-1 %. It is also possible that 
String object uses wrong encoding that doesn't include ñ. See API for 
java.lang.String for that..

Hope this helps,
Vlad

 Subject: Problem with spanish accents and the 'ñ' char


 I'm running Tomcat 5.0.16 and a JSP that connects to a MySQL DB. The 
data in the DB is ok, because i fetched that information with a quick php 
application and it displays correctly the accents and such. But when i 
access the information with this JSP, it puts question marks instead of 
those characters. I've seen this problem in some forums out there, but no 
solution... The same JSP is running on a Tomcat 4.0.1 in another machine 
(that i haven't configured), and it displays the accents correctly.
 Does anybody know what to do ?

  What is the value of the string that you are passing to setString? Is it
  null? If it is, then I'd call this expected behavior.
 
  If you want to set the value of a column to NULL then you must use
  PreparedStatement.setNull().
 
  Sheesh, at a 615 level course you should be checking for nulls.

parameter null if an equal sign in the value of the jsp:param?

Hello all,

I haven't had much luck locating any information regarding this. And I am

I am using Tomcat 4.0.6 and when passing a parameter with jsp:include if 
the value of the parameter contains an equal sign (=) parameter is absent 
(or null?) from the request of the included page.

Has anyone seen such a behavior?

Wade, thanks for your response.

I am not sure if i phrased my question correctly. But i think I am getting 
to something based on your response. What I am trying to do is:

in one jsp i have

jsp:include page=another.jsp
jsp:param name=something value=something=somethingElse/
/jsp:include
as a result of this include, request.getParameter(something) in 
another.jsp returns null;

As I was writing this email I figured it out.. I have to use %3D instead of 
the = and it's all fine

Thanks for your help;

application scope variable lost

2003-07-28 Thread Vladimer Shioshvili
I have three contexts running basically the same application. (one is 
semi-production, and two sandboxes). All of them having bunch of hasmaps in 
the application scope to use as a reference. there is only one servlet per 
application that actually does writing to these hashmaps, the rest of the 
pages/servlets only read the values. the servlet that creates the hashmaps 
is loaded on startup and has no doGet, or doPost methods. everything seemed 
fine until this morning out of blue i noticed that all three contexts have 
empty hashmaps. they were fine earlier this morning though.

this is something i was not ready for.. any clues or suggestions what could 
be the cause? any help is appreciated..

Re: application scope variable lost

Thanks Jon,

the code doesn't empty hashmaps, unless it is rerun and somehow data is not 
retreived from the source (the source is SAS data set, which seems to be 
quite a pain when dealing with locks). I guess I will have to consider 
using listeners, but i am still curious how could all three get empty at 
the same time? could it be that garbage collector claimed all three at the 
same time?

thanks,
Vlad

Even though your Servlet is loaded on startup the container (ie tomcat) is 
free to unload and reload servlets at any time. This is why it is so much 
better (IMO) to use ServletContextListeners for application configuration. 
Does your servlet create empty maps even if they already exist on the 
context? If so, the behaviour you are seeing is probably a reload of your 
Servlet. (Weird that all 3 apps showed the same behaviour at the same 
time, though)

Tomcat jsp file is locked on win32

2003-07-15 Thread Vladimer Shioshvili
Hello all,

I am not sure what could be the reason for this behavior. I did not have 
much luck finding any information on the web about this either. One 
particular jsp file is being locked and cannot be deleted. I am trying to 
update the file and replace with an updated copy from CVS, but because of 
it is locked it can't be done unless Tomcat is stopped. Out of 30 or so jsp 
pages I am using for the project this is the only one that gets locked. The 
only difference is that the file is the biggest (41K). Is that the reason? 
Also, if you could point me to where I should be looking for an answer to 
this question, would be greatly appreciated.

Thanks,
Vlad

Re: Log4j problem mixing 2 apps

2003-06-26 Thread Vladimer Shioshvili
easiest solution is to use log4j in the context scope, instead of 
application scope. meaning that you put your log4j.jar file in web-inf/lib 
of every context, instead of some central location. each application will 
have to configure the logger separately after that, and you will have no 
interference.

cheers,
Vlad

What might I have done to cause this problem? It looks like the
application that has been deployed last gets all the log messages.

reposting: error page for basic authentication

2003-06-10 Thread Vladimer Shioshvili



Is it possible to define an error page for the basic authentication? and 
if yes, how/where? i have tried to define error-page for code 401, but 
realized that i am using constraint on everything , thus i am guessing 
that error page may be falling under the constraint as well. (not sure 
about that though..)

Thus, how can i  modify HTTP Status 401 - Unauthorized to be what i want 
it to be? all i basically want is to have a little more attractive message 
saying sorry, your not allowed in there, or something like that..

I've tried to look for the solution on the web, but didn't have any luck. 
Any help is greatly appreciated.

i have asked a question couple weeks ago regarding combining filtering by 
ip and authenticating by username/password.. thanks all of you who gave 
suggestions. i finally got to get to it and have a valve working, but now i 
have another problem..

i return a response with SC_UNAUTHORIZED if user doesn't have a specific ip 
address.. but then i think i am missing something and i get authentication 
window three times and then get 401 error..

i am assuming that i am missing realm setup. any lead would be greatly

RE: Reloading class file without disturbing users?

2003-05-30 Thread Vladimer Shioshvili
that all depends if he has it set to be serialized (by default they are 
serialized).
but there is a chance of disturbing users if something that is stored in 
the session is not serializable.

reloadable will indeed replace old version with new one, servlet once it 
detects the changes. but using reloadable=true is not suggested in the 
production mode (it takes some CPU time). but even this has a chance of 
disturbing your users. (can't think of a good example, but there is a 
chance of getting a null pointer exception).

 Subject: Reloading class file without disturbing users?


 Greetings

 I haven't found the answer to this in the documentation.

 I have a jsp that invokes an instance of a java object. I would like to
 modify the java file and have the change take effect without
 interrupting any users that are on the system. If use the
 manager/reload?/path method to reload the application, will it interrupt
 any active sessions? (The documentation does say it will shut down the
 application. That sounds like the sessions die, but maybe they're
 handled at a higher level.)

 If I put reload=true in the context definition in server.xml, will the
 application then reload class files in the path /WEB-INF/classes when it
 detects there is a more current version? Or does this just apply to
 servlets and jsps?

 Thanks

 Mike

error-page question...

someone probably has asked this question before and it's not exactly (or 
maybe it is) Tomcat question..

i have a header that i am including in every page of the application, and 
then i have an error page for errors. i want to include header in the error 
page so it looks like a standard page.. but header itself may cause a 
problem as it's not plain html, and i would get a recursive action.

any quick suggestions?

  I'm playing with the Tomcat example jsp files, specifically the

  I can add a statement like:  %= new java.util.Date() % br /
  to kick out the current date as a string, but when I try to access
  a java class
  I've written, I get a 'cannot resolve symbol'.  The error happens
  as the jsp is
  being compiled.
 
  Here's the offending statement:
  %= Yada.getString() % br /
 
  Here's the class definition:
  public class Yada {
  public static String getString() {
  return Hello from Yada.getString();
  }
  }
 
  The Yada.java and Yada.class file lives in the WEB-INF\classes directory.
 
  The WEB-INF\classes directory is in the classpath as per the screen dump
 I'm
  getting.

Re: user clicks submit but nothing happens

are you using get or post method for the form? explorer can't handle large 
headers with get method and submit doesn't do anything...

At 05:31 PM 4/3/2003, you wrote:
Newbe question:  I am trouble shooting a problem we had with our server.
The problem seemed simple; when the use clicks, a submit button, JavaScript
will check the data in the form, then call the document.form1.submit(). The
form action then sends the data to the servlet.  Normally the servlet  would
handle the request and process the data but the servrlet never starts.
Instead, the page and form reload.  This problem occurs infrequently when we
test in house, but when the client is working with the system, it happens
quite often.
I need help to figure out a way to isolating this problem.  The problem must
be between the Clients Browser, tomcat, and servlet.  Suggestion would be
much appreciated.  I've been looking for a solution and pattern for several
days.

if you are using tomcat as a service what java_home is does not matter, as 
jvm path is hardcoded in the registry..

open regedit  and find

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\%name of your tomcat 
service%\Parameters

%name of your tomcat service% will be something like apache tomcat 4.0 or 
whatever the name of the service (i tend to change mine, thus don't know 
what default is...) and one of the parameters is JVM library.. that's what 
determines the JDK (I am pretty sure..) try to change that to the one you 
want to use..

I am loosing contents of the log file for System.out every time tomcat is 
restarted. tomcat, instead of appending to the file, overwrites it. (same 
with System.err)

I am using tomcat 4.0.6 running as an NT service on a win 2K box. thus, the 
question is, is there a way to either make tomcat date the file, or append 
to it?

Thanks,
Vlad

Re: Servlet help

Sandra,

if you are planning to do the changes often you are probably better off if 
you set reloadable parameter to true in server.xml file, 
(http://jakarta.apache.org/tomcat/tomcat-4.0-doc/config/context.html) 
however, setting it to reloadable means that you should accept that it will 
eat up some of your CPU time as well (not a significant one, but it's 
there).. otherwise, compiling your file, and restarting tomcat should 
suffice...

I have tried just saving it. I have tried restarting Tomcat. I have tried

while Tomcat was running. I have tried restarting the machine. Only
restarting the machine seems to work.
Comments? Suggestions? Ridicule?

tomcat restart

2003-03-07 Thread Vladimer Shioshvili


We have a weekly scheduled restarts of all the servers. One of servers has 
tomcat that i am overlooking. i am running tomcat on a windows 2000 server 
as a service and noticed that when the computer is restarted tomcat does 
not throw a shutdown event log item. is this normal, or should i be worried 
about it? as much as i know windows is properly restarted (by systems 
people)...

Thanks in advance
Vlad

tomcat and SAS

2003-02-21 Thread Vladimer Shioshvili
Hello all,

does anyone have experience with making SAS spawner and tomcat. 
Installation was successful, the whole thing seems to be working, but out 
of blue tomcat starts hogging CPU (99%) and once restarted bunch of SAS 
spawner errors appear in the application log in windows event logger.

Thanks for your help,
Vlad

tomcat NT service memory

2003-02-03 Thread Vladimer Shioshvili
Hi,

I am experiencing problems with Tomcat because of default JVM memory size 
and want to let it use more memory. The only way i know is to change/add 
environmental variable for the service in the registry 
(CATALINA_OPTS=-Xmx256m)... However, i am not sure if this is the 
best/correct way. Could anyone either confirm that this is the correct 
approach, or give me suggestions.

Thanks,
Vlad

Re: Console output in Tomcat

2002-12-31 Thread Vladimer Shioshvili
Raj,

This is what happens with Windows (i am not sure how is it in Linux 
environment). If using tomcat as a service, output goes to a log file 
stdout.log (it's defined by default in the service configuration) located 
in %tomcat_home%\logs folder. Along with that you will find sterr.log that 
has System.err.out(..) output.

RE: Console output in Tomcat

Sumit,

i am not trying to get into an argument and plus i haven't dealt with 
4.1.12 (i checked both 4.0.6 and 4.1.18). The only difference is that i am 
talking about running tomcat as an NT service and if your System.out File 
and System.err File values are set in the service properties in the 
registry (they are there by default) then all of the System.err and 
System.out output is logged in the appropriate file. Again, i am not sure 
about non-NT service.
cheers

 Unfortunately no. The output from System.err doesnt get logged not with
Tomcat4.1.12. I had run in the same problem a couple of days before and the
only alternative was to install cygwin and redirect the output to a file.

RE: Virtual Hosting with Tomcat

2002-12-31 Thread Vladimer Shioshvili
Mike,

in server.xml file in conf folder find connector tag (in new version it's 
coyteconnector, in old version it's httpconnector) (or just search for 
8080) and replace 8080 with 80. that will eliminate need for :8080.

also in server.xml, for the webtop context, make path= and webtop's 
index.htm(l) will become default page. it will be something like this..

Context path= docBase=webtop debug=0 
reloadable=false/

Cheers

Hi there,

Many thanks for the info.  I am still having the following problems I
hope you can help with.

A)  Our domain name is seewithin.stc.com.  The application is in a
folder called webtop.  I would like the default location to be the
webtop folder.  However no matter what I do, when I type in
seewithin.stc.com:8080, it goes to the default Tomcat page.

B)  I would like to leave out the port number in the address.  Is there
a way to configure this?

Many many thanks for all your help!

I'd say to just send requests directly to Tomcat on it's port..usually
8180 or 8080

http://yoursite.com:8180

then edit the server.xml file to point to where you want it to serve
your webpages. Here's an example config:

Host name=yoursite.com
  Context path= docBase=/home/mydirectory/public_html debug=0/
Aliaswww.yoursite.com/Alias /Host


you'll put that in your server.xml file in between:

  Service name=Tomcat-Standalone
!-- Define the top level container in our container hierarchy --
Engine name=Standalone defaultHost=localhost debug=0

Host name=yoursite.com
  Context path= docBase=/home/mydirectory/public_html debug=0/
Aliaswww.yoursite.com/Alias /Host

/Engine

  /Service

Hi there,

I need to setup virtual hosting with Tomcat.  We are not running the
full Apache server, just Tomcat and its web piece.  Can this be done?
Everything I have found so far refers to Apache not Tomcat on its own.

Any help would be greatly appreciated.

Thanks,
