Subject: Access zu an jdbc Datasource

Hello List,
I'm trying zu connect to an JDBC Datasource connecting to an Postgres 
Database. But it will not work.

I tryed it link the Documentation, adding the Datasource under 
GlobalNamingResources, and add the another in web.xml.

In ProgrammSource:
--- cut ---
Context initContext = new InitialContext();
Context envContext = (Context)initContext.lookup("java:/comp/env");
DataSource ds = (DataSource)envContext.lookup("jdbc/postgres");
Connection conn = ds.getConnection();
--- cut ---
The another is link the description in the JDBC Howto.
While ds.getConnection() i recieved an Exception, cannot connect to 
Datasource name ''.

Searchin a little bit, i cannot find the Environment for the 
Postgresdatabasesource.

Does anyone has an Idea / Howto i can lokk about my Problem??
Thanks for Help
\Robby

Is there any story on the version number "hyper-jump-to-warp-speed"? 5.0 
is current, I can see links to 5.1. Why have you jumped to 5.5? Because 
of JDK 1.5?

Nix.

Re: How do I read only the XML data in doPost(req,res)?

[Kimmy Lin]

What I really meant was to write a parameter "xmldoc=..."
into the outputstream of the HttpURLConnection like the following to make it
a Post.

OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(params);

Not sure whether there is any limit this way though.

But Request#getInputStream() does provide the request body w/o the header.

Re: [ANN] Apache Jakarta Tomcat 5.5.0 Released

[guo yingshou]

Great! 

But I cann't build it with the downloaded build.xml on
jdk5 beta2. There are some generics related problems
with dbcp compilation. Use jdk1.4_05 to build is ok
but I have to switch to jdk5 to run it.

We run 4 instances of tomcat-5-24 in a cluster
environment in our production system. We met some
problems and looking forward to a better release. 

Thanks for your hard work!

UTF-8 Encoding Issue Since 5.0.27 ( gun in my mouth )

[Rick]

Since 5.0.27, pretty much all of my UTF-8 i8 code seems to be messed up. 

The problem seems to have been caused by whatever fix was created for issue
--
ServletResponse.setContentType sets response encoding after getWriter was
called (Bugtraq 5062838) (luehe) 
--

Now it seems almost impossible to properly set the encoding type of some of
my JSPs and all of my Servlets that return UTF-8 XML data.

As an example, my login page allows the user to switch to Japanese text.
Text data is read with a ResourceBundle, which reads from a UTF-8 encoded
.properties file.

If the encoding of the .jsp page itself is in ASCII, then I can't get the
characters to show up at all any more.
I have to save the .jsp page as UTF-8.  
Added "set JAVA_OPTS=-Dfile.encoding=UTF-8" to my catalina.bat file

Then, If I try to set a character set in my page header, it messes up.

This works in some cases...
<%@ page language="java" import="java.util.*" contentType="text/html" %>
response.getCharacterEncoding() = "ISO-8859-1"

The really scary part is that with no meta or charset actually set, that the
browser(IE) correctly changes to UTF-8 and displays the content fine.   But
if I change the actual file encoding of the .jsp page from UTF-8 back to
ASCII. Then IE does not change to UTF-8 and the page is messed up again.
Why does the actual encoding of the .jsp file itself dictate the response
sent to the client?

It appears that the actual encoding of the source file someone how gets past
along and then I'm unable to alter the character encoding, and if I try, it
just causes everything to go to hell.


This use to work before 5.0.27, but now doesn't, even though all data and
pages are encoded in UTF-8.
<%@ page language="java" import="java.util.*" contentType="text/html;
charset=UTF-8" %>
response.getCharacterEncoding() = "UTF-8"


Before 5.0.27, all I had to do to get my output in UTF-8 was ...
 contentType="text/html; charset=UTF-8"

Now I have to mess with the actual .jsp file page encodings and still can't
get most to work properly as well as none of my servlets will return correct
UTF-8 data.  

I have tried setting "pageEncoding" in the page tag as well with no luck.


Thanks for anyone's insight or help on this, its never fun to find out that
something that had been working quite solid , up and blows up for no good
reason.

Current dev machine is on windows xp by the way, vanilla install of Tomcat
5.0.28.
I will be setting this up on a Linux box for more testing shortly.

[ANN] Apache Jakarta Tomcat 5.5.0 Released

[Yoav Shapira]

The Tomcat Team announces the immediate availability of Apache Jakarta Tomcat
5.5.0. 

This is the first release of the new Tomcat 5.5 branch, and as such it is not
yet stable. We expect significant additional changes, including possible
changes to packaging, dependencies, and Tomcat internal APIs, before the first
5.5 stable release is made. 

Please note that we are still in the process of updating documentation for this
branch. Of special note is the JRE 5.0 requirement: running with JRE 1.4 is
also possible, and instructions are provided with the distribution.

Well, that's what the target would be. The idea is to re-use connections
so you don't spend as much time tearing down the Java interpreter and
rebuilding it. CGI will start a new Java process for every connection,
and when the connection is done tear it down.

So you might want to check that you haven't enabled pooling accidentally.

website going down

[Stephen Charles Huey]

We had a problem where our website would hang because Tomcat couldn't
access the main database over DSN (on another machine), and it was a
problem with our vendor's ODBC driver, so we moved to the Linux version
(which was more stable).  We had created a Watchdog program that would
call a JSP with simple database access, and it would restart Tomcat
whenever the problem occurred (although that sometimes wasn't
sufficient--sometimes we would also have to go in and manually restart
the ODBC driver).  Anyway, our problems have lightened considerably, and
consequently our watchdog program doesn't have to do much, although from
once in a while it does restart Tomcat for us.  

However, we are now seeing a new problem.  The watchdog program will
keep going along as if there's no problem, and yet the website will be
hanging!  Because there was a problem in the early days of development
with using the main database for the basic authentication used to enter
our website, we set up a MySQL database on the same machine as Tomcat
and have it access that small database locally by telling it to use
JDBCRealm in our server.xml file.  The watchdog program doesn't access a
secure JSP, so it doesn't really have to log in.  

In other words, as far as I can see, Tomcat must be trying to go to
MySQL to pop up that basic authentication box, but the box never pops up
because I suppose MySQL is hanging for some reason.  Generally all we
have to do is restart Tomcat to get everything back to normal.  My
question is, do you know of any reason why MySQL would be doing this?  

Thanks,
Stephen

Re: How do I read only the XML data in doPost(req,res)?

[Kimmy Lin]

Do you have control over how the request is composed?
If so, you can put the XML data in a parameter say "xmldoc"
and the equivalent GET request will look like the following

http://URL?xmldoc=...

("<" and ">" not escaped)

Then in your program do

request.getParameter("xmldoc");

to get the xml data.

RE: Reading Servlet OutputStream

[Nitin Mulimani]

The issue being how do I write to PipedOutputStream().
These are the lines I'm thinking ..

PipedOutputSteam out = new PipedOutputStream();
out.write(ServletOutputStream.read());

But I do not know a way to read data from an output stream

How do I read only the XML data in doPost(req,res)?

I'm receiving a HTTP POST request containg XML data and want to process the data in 
the doPost method of my servlet.  When I do request.getContentLength(), it gives the

portion of it.  I can't find any Java methods which will return only the data part of 
the request.  How can I do this?

You were right!!  I don't know where I got that web.xml file from but when I
put those lines into the one out of my war file it worked.

Thanks to those who pointed out about the syntax of the xml file. Iit made
me go back and check and that's when I realised I'd picked up the wrong
web.xml.

Thanks

RE: How do I get an intermediary proxy from caching?

I don't agree with your assesment.  I would rather do a simple boolean
check before I do something and make a decision based on that and use
exceptions for catastrophic errors.  Just a choice in how to use the tools

You're missing the point.  The infrequent case is that the output is already 
committed, not that you'll be adding headers.  You're including an error check in the 
main path that would be perfectly well handled by an exception.

Thanks Keith,
I figured out what I did wrong.  It turns out that my logout servlet was 
running in a separate Web application that is not part of the SSO 
Realm.  Of course, session.invalidate() does nothing to the SSO 
session!  Thanks a lot for your help!

However, you're adding code for a hopefully infrequent situation to the main path.  If 
you simply catch the exception, you don't impact the main path.

To rely on that method, yes a bad design, to check before you change the

For one, check the archives: this topic comes up frequently.  You'll
have to write some code to do this.

Second, I'm surprised this topic isn't covered in the Lucene docs.  This

HttpServletResponse has an isCommitted() method.  That will tell you

I took the file itself out of the equation and just reference a path to a
series of files that I have on a locally mounted CDROM.  So the form parsing
that FileUpload is doing is just taking apart the form fields to direct
processing.

These were one after another.  Once on form was processed the next was sent.

This is via a submission of a form within the Java environment to a URL.

The problem is that keeps growing over time.  On a production server, the
process size hits 1.6GB.  Again, the java heap is smaller in the order of
600MB.

Re: tag file encoding problem

[V. Karthik Kumar]

use: 

response.setCharacterEncoding("Whatever"); <-- internally, this is what
the tags translate to...

Before u carry on with out.print() statements...

And one more thing.. there is an option available to add encoding
messages by default; a filter is available by default

filters.setCharacterEncodingFilter

look in the servlets-examples\WEB-INF\web.xml

QM,

Open and read files...
Lucene has indexed files under e:\data
And after a Lucene search (from indexe) Lucene display something like that

http://merlin:9090/data/text/essai.txt
With
Etat HTTP 404 - /data/text/essai.txt

Webapp Lucene is installed and running from 
D:\Program Files\Apache Software Foundation\Tomcat 5.0\webapps\luceneweb

You'll have to clarify what you mean by "access" -- open a file, write a

Whatever the case, barring any SecurityManager problems or issues with file
ownership/permissions it should be a standard java.io.* issue.

you could also use a filter for your whole app that does that, if you 
want all your app "non-cached", same rules apply

Hi!

[V. Karthik Kumar]

Hi,

I'm reporting this some sort of unusual behavior in the manager...  (WRT
Tomcat 5.0.27) ... 

When a user tries to start a web-app that has been started already, and
then stop it, it becomes unusable again... The current way to solve such
a thing is:

1. Shutdown the server
2. Clean up in the work/Catalina and work/Standalone directories
3. Re-start the server

Regards,
Karthik.

You can get access to the Subject by doing

Reading the specs tells me that the functionality is meant for

The way SJSAS 8.x is doing that is by using the Subject and then the

Help, URI mapping problem with JK2

[John Gentilin]

I am running Apache 2.0.50,  mod_Jk2 and Tomcat 4.1.30. 
In my workers2.properties  I have the mapping

[uri:/WebClassifieds/*]
group=lb
where this URL works
http://4wallsinde.rapidxsl.com/WebClassifieds/web/cmd/
and this one too
http://4wallsinde.rapidxsl.com/WebClassifieds/fourwalls/V20/assets/ext/logos/NJlogo.gif
but this one DOES NOT work
http://4wallsinde.rapidxsl.com/WebClassifieds/web/cmd/4walls/Apartment/Search/Listing/Guide/For-/DE/LocationPath/%2FDE%2FNorthern+DE%2FBear/encoding/cyacaakef_enc_GetLocation.xsl
Apache reports a 404 error but nothing else
[31/Aug/2004:10:43:25 -0700] "GET 
/WebClassifieds/web/cmd/4walls/Apartment/Search/Listing/Guide/For-/DE/LocationPath/%2FDE%2FNorthern+DE%2FBear/encoding/cyacaakef_enc_GetLocation.xsl 
HTTP/1.1" 404 442

It almost seems as if mod_jk passed up on the redirect. My problem now 
is that I can't get any debug information to be produced
so I am stuck...

I added this block of  confog to my jk.conf file
JkSet2 logger level debug
JkSet2 logger.file:0 file /usr/local/apache2/logs/jk2.log
JkSet2 logger.file:0 level debug
but all that did was create a log with 3 entries saying that logging was 
enabled and that was that...

Thansk you in advance.

--mark

How large were the files you were uploading?  I mean  you just said you 
uploaded 500 files.  You should expect to see process memory growth. The 
JVM has it's own object heap where it manages it's "internal" memory.  
Then there is the process and it's memory which is a C heap.

I see that you uploaded 500 files.  Were these one right after the 
other, or were they close to simultaneous?  Also, how are you uploading 
the files?  Are you using some type of a parser?  Are you using the 
commons file upload control?  If the JVM reports good memory collection, 
then there is no memory leak in Tomcat.  31MB of growth for a process 
uploading 500 files shouldn't be that bad depending on how they were 
uploaded and file sizes.

Think about it. If the files were between 100kb and 60kb then you have a 
total of 30mb to 50mb of memory just in that data alone not including 
your application and other buffers you may or may not be creating while 
uploading.

For perforamnce reasons the VM isn't going to suddenly resize the heap 
as soon as it frees a group of java objects because as far as it knows 
you may come along and upload 50mb worth of data immediately after the 
first.  This is a performance thing.  Resizing the heap takes time and 
cpu resources and affects performance.  The VM will reuse this memory 
over and over again.

I would look at any loops I might have reading from the stream.  Do you 
create a bunch of small byte array's while uploading the files?  Maybe 
you could increase the buffer size, be sure to null them out after you 
perform a read to tell them VM you are done with the variable now (for 
when the vm collects), and then see if that affects the memory growth.   
This should help speed the file upload a bit and get rid of some buffers 
in loops a little quicker if you aren't nulling the array.  If however 
you are simultaneously uploading much of this data, then a 31mb spike in 
memory usage shouldn't be a suprise no matter what.

Basically you can impose limits on the VM and you can use switches to do 
this.  You can also devote more memory to eden or survivor objects so 
that the VM can make better use of the most commonly used memory.  You 
can find more info on this topic and others at this url:
http://java.sun.com/docs/performance/
Many docs.  One for you might be:
http://java.sun.com/docs/hotspot/VMOptions.html
scroll down to the bottom and check out options:
-XX:NewRatio
-XX:NewSize
-XX:SurvivorRatio

Basically the defaults for the -server VM are to allow the best 
performance for a multi user multi threaded application such as tomcat. 
 So, unless you are running out of memory or you need to cripple the app 
servers performance by limiting it's growth because you have a bunch of 
other applications running on the same server, then I suggest sticking 
with the defaults.

Just noticed you wrote about the upload component.  I haven't looked at 
that code's parse to see how it is handling reading bytes from the 
stream, but I'm sure there have been many eyes on it.  I would say this 
is probably just a memory usage over time issue (short period of time). 
 Use those links I gave you and play with the memory switches a bit to 
see if you can get some kind of a situation that works best for you. 
The switches:
-XX:MaxHeapFreeRatio
and
-XX:MinHeapFreeRatio

Can make the vm resize the heap differently, but you will want to be 
careful.  You may make things very slow by messing with the defaults for 
those switches.

stay with the range for the initial numbers.
 
My question is what would you recommend to isolate the process growth?
 
Is there a way within Java to see the underlying process growth to help
isolate it in the processing cycle?
 
--mark

How large were the files you were uploading?  I mean  you just said you 
uploaded 500 files.  You should expect to see process memory growth. 
The JVM has it's own object heap where it manages it's "internal" 
memory.  Then there is the process and it's memory which is a C heap.

I see that you uploaded 500 files.  Were these one right after the 
other, or were they close to simultaneous?  Also, how are you uploading 
the files?  Are you using some type of a parser?  Are you using the 
commons file upload control?  If the JVM reports good memory collection, 
then there is no memory leak in Tomcat.  31MB of growth for a process 
uploading 500 files shouldn't be that bad depending on how they were 
uploaded and file sizes.

Think about it. If the files were between 100kb and 60kb then you have a 
total of 30mb to 50mb of memory just in that data alone not including 
your application and other buffers you may or may not be creating while 
uploading.

For perforamnce reasons the VM isn't going to suddenly resize the heap 
as soon as it frees a group of java objects because as far as it knows 
you may come along and upload 50mb worth of data immediately after the 
first.  This is a performance thing.  Resizing the heap takes time and 
cpu resources and affects performance.  The VM will reuse this memory 
over and over again.

I would look at any loops I might have reading from the stream.  Do you 
create a bunch of small byte array's while uploading the files?  Maybe 
you could increase the buffer size, be sure to null them out after you 
perform a read to tell them VM you are done with the variable now (for 
when the vm collects), and then see if that affects the memory growth. 
  This should help speed the file upload a bit and get rid of some 
buffers in loops a little quicker if you aren't nulling the array.  If 
however you are simultaneously uploading much of this data, then a 31mb 
spike in memory usage shouldn't be a suprise no matter what.

Basically you can impose limits on the VM and you can use switches to do 
this.  You can also devote more memory to eden or survivor objects so 
that the VM can make better use of the most commonly used memory.  You 
can find more info on this topic and others at this url:
http://java.sun.com/docs/performance/
Many docs.  One for you might be:
http://java.sun.com/docs/hotspot/VMOptions.html
scroll down to the bottom and check out options:
-XX:NewRatio
-XX:NewSize
-XX:SurvivorRatio

Basically the defaults for the -server VM are to allow the best 
performance for a multi user multi threaded application such as tomcat. 
 So, unless you are running out of memory or you need to cripple the 
app servers performance by limiting it's growth because you have a bunch 
of other applications running on the same server, then I suggest 
sticking with the defaults.

You'll have to clarify what you mean by "access" -- open a file, write a

Whatever the case, barring any SecurityManager problems or issues with
file ownership/permissions it should be a standard java.io.* issue.

Java process growth under Linux...leak?

[Mark Maigatter]

We have a Tomcat 5.0.25 based web site for uploading images and assorted
files and managing them.
 
We have found that the Java process that Tomcat is running under is
gradually growing when repetitively processing files uploaded and stripped
out of the form submissions by the Apache FileUpload component.  All signs
point to a memory leak?
 
Upon the submission of about 500 files we had a 31MB growth in the size of
the java process using "top".  
 
However, the Sun Java jvmstat shows that the Java heap is staying relatively
constant.  The "-gc" numbers fluctuate in a manner that shows reasonable
garbage collection activity and the total used across the s0/s1/eden/old
stay with the range for the initial numbers.
 
My question is what would you recommend to isolate the process growth?
 
Is there a way within Java to see the underlying process growth to help
isolate it in the processing cycle?

AW: JSP/HTML Encoding

[Ben Bookey]

Hi Allistair

+++ Many thanks for your help. +++

I apologise when I ask some stupid questions...
:)

1) I am not exactly sure what the benefit is, of seeing if the client is
posting a utf8 encoded response ? Surely, the server controls anyway what
encoding the html pages are in so if i post with Latin9 then the client can
either read it or not. I guess this filter is useful in the case that the
client browser doesnt support the character encoding (something hopefully
similar) and posts the request in another character-code. The filter can
then be used to see if this is happening or not ?


2) I would assume that Tomcat( being java) would always use either utf8 or
utf16 so making the necessity of setting a jvm tomcat property unnecessary ?



regards
Ben

Hm, tell a lie Ben...I've just checked our startup options and we don't seem
to do that anymore ... however if you were to do it ..
add -Dfile.encoding=utf8

I think you just need to make sure you use utf8 at the UI. Our databases are
all Windows Cp1252 which also include the euro symbol.

I also forgot to mention we put an explicit filter on all inbound requests
that set the inbound encoding to utf-8. Try adding this filter to web.xml

SSL Discoveries

[Bill Barrington]

  If you are using SSL with Tomcat, you should probably read this. I got no responses 
to my earlier postings, but it's possible this could save you some time in the future. 
Or it could be that my experience is totally unique (but that is hard for me to 
believe).

  I finally got SSL working with Tomcat by blowing away my keystore and starting over 
from scratch. I discovered some things along the way. Tomcat doesn't actually care if 
you have a key with an alias of 'tomcat'. I created a key (the only entry in the 
keystore) with an alias of 'woof' and Tomcat was quite happy with that. The SSL 
connector initialized fine.

  If you enter 'https://localhost:8443' (or whatever your SSL port is) in a browser 
and view the certificate, it will show the certificate with the alias of 'woof'.

  Now add another key with an alias of 'tomcat' and bring up the browser again and 
view the certificate.  It will show the one with the alias of 'tomcat'.

  If you then delete all entries from the keystore and restart Tomcat, it will go into 
an infinite loop trying to initialize the SSL connector.  Now add a key (any key) and 
it will come up, no problem.

  Tomcat appears to only care that you do have a keystore with at least one key in it. 
Doesn't really care what that key is, just a non-empty keystore to make it happy.
  
  I did save all of my existing keys before I blew away my keystore and started over. 
I imported them back into the new keystore and everything was fine. At first I thought 
that maybe a key was corrupted, but that does appear to be the case.

  I'm running Tomcat 5.0.27 & JDK 1.4.2_03.

Functionality of for Servlets

[Gunnar Brading]

I have been in need of using the  tag in a Tomcat-only 
environment... Is this possible? Reading the source indicates that it 
wouldn't be possible to get the information about the role the context 
currently is in. Using the requests in-role methods of course tells me about
the user, and not the context.

Have I come to the right conclusion?
Reading the specs tells me that the functionality is meant for 
transferring roles to EJB's. Some documentation I found at Sun indicates 
though that even web-applications should be able to use this.

Anyone got more information about this?
Cheers,

Just one -- perhaps the IPs in question do not resolve to hostnames.

Put another way, those IPs may not be resolvable from the Tomcat host.

Re: Tomcat Holding Database Open??????

[Parsons Technical Services]

Mike,

You may want to post some code and let us take a look. May be the simplest
solution to get you going. There is a chance that you are not closing the
connection properly and it is being held open. There can also be database
issues as well (I think someone mentioned this).

make sure also that you set file.encoding=utf8 in tomcat's startup options

RE: JAVA_OPT with service

[David Morris]

Sloan, 

You should find what you need here:

http://jakarta.apache.org/commons/daemon/procrun.html

Look in the registry for the parameter keys:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\\Parameters

JVM Option Number 0 to the first parameter.
JVM Option Number 1 to the second parameter.
JVM Option Count (DWORD) is the number of parameters.

IllegalStateException from java.nio.charset.CharsetEncoder

[Greg Ward]

On one of our servers, we're using Tomcat 4.1.29 under Java 1.4.2_02,
connecting to Apache 2.0.48 with mod_jk 1.2.4, all running on Red Hat
Linux 6.2.  (Wow, what a zoo of version numbers!)

Recently we got a support call because some (all?) HTTP requests were
failing with "Internal Server Error".  The support tech who took the
call noticed this in mod_jk's log file:

[Sat Aug 28 15:59:39 2004] [jk_ajp_common.c (1309)]: sending request to tomcat failed 
in send loop. err=2
[Sat Aug 28 15:59:39 2004] [jk_ajp_common.c (1318)]: Error connecting to tomcat. 
Tomcat is probably not started or is listening on the wrong port. Failed errno = 104 

(Errno 104, for the curious, is ECONNRESET -- "Connection reset by
peer".)

He tried restarting Tomcat, which sounds like the right thing to me.
That didn't help, so then he tried restarting Apache.  Still nothing, so
he rebooted the server, after which things started working again.
H.

Looking in catalina.out after the reboot, I saw this stack trace:

  java.lang.IllegalStateException: Current state = FLUSHED, new state = CODING_END
  at 
java.nio.charset.CharsetEncoder.throwIllegalStateException(CharsetEncoder.java:933)
  at java.nio.charset.CharsetEncoder.encode(CharsetEncoder.java:529)

  at org.apache.ajp.tomcat4.Ajp13Processor.run(Ajp13Processor.java:576)
  at java.lang.Thread.run(Thread.java:534) 

Of course, catalina.out is clobbered with every Tomcat restart, so
there's no way of knowing if this exception is actually the cause of the
problem, i.e. if it was happening before the first Tomcat restart.
Nevertheless, I poked around a bit and stumbled across these two entries
in Tomcat's bug database:

  http://nagoya.apache.org/bugzilla/show_bug.cgi?id=7725
  http://nagoya.apache.org/bugzilla/show_bug.cgi?id=6519

Both of these have a *nearly* identical stack trace (the connector is
different -- org.apache.catalina.connector.http.HttpProcessor vs
org.apache.ajp.tomcat4.Ajp13Processor in my example) that ends with the
same IllegalStateException.  Both are about 2 years old, around the time
that Tomcat 4.0 and Java 1.4 were in beta.  And it sorta-kinda-vaguely
sounded like the bug(s), whatever they were, have been fixed.

First of all, from those two bug reports, it's not clear if this is a
Tomcat bug or a Java bug.  Second of all, has anyone else seen this on
stable, mature versions of Tomcat 4.0 and Java 1.4 (ie. 4.0.29 and
1.4.2_02)?

Thanks --

Greg

JSP/HTML Encoding

[Ben Bookey]

Dear List,

I am having unexpected results when setting the encoding of my
inputForm.jsp, to iso-8859-15 (changing from
iso-8859-15 to iso-8859-1 will allow me to use the Euro symbol and a few
others). When i give a Euro symbol into a form input control, the client
ends up saving a question-mark instead, which is exactly what happens then I
leave the standard iso-8859-1 encoding(the jsp default). I am using Tomcat 5
and Internet Explorer 6.x which supports charset=iso-8859-15.

Here is my jsp page header attributes.

<%@ page language="java" errorPage="myErrorPage.jsp"
pageEncoding="iso-8859-15" contentType="text/html; charset=iso-8859-15"%>

If by setting the above jsp attributes, do I still need to set (inside the
 tag) like this ?



Another factor which might be affecting the encoding of my input form, is
that its a page within a frameset, and it could be that the parent frame
HTML page might be incorrectly pre-determining the encoding of the whole
frameset overriding the child frame settings.


kind regards,
Ben Bookey

Re: Tomcat 5 & Crystal Reports

[Brent Sims]

Use CR version 9+ -- it provides a tag library and supporting files that allow you to 
include your report in a jsp or servlet.  You'll still need an ODBC definition to 
create the report against but this should not be a problem as long as the ODBC def and 
the JNDI resource share the same name.
 
Now, if someone has a fix/answer to the problem I've been banging my head against of 
only being able to run the report once (subsequent attempts cause something along the 
lines of a ZipExtraction exception), I'd certainly appreciate a clue or three

Hi! I'm triying to configure Tomcat 5 and Crystal Reports. What I want to do is 
reading from a database to a report made with CR using a Tomcat datasource. The 
problem is that CR can't find it (using jndi); i get a message saying that CR is 
unable to find the resource. The datasource is well defined (i think so because a jsp 
can use it correctly).

Does anybody know if is there problem between Tomcat 5 and Crystal Reports? Is there 
any one that have configured it yet?

RE: Access Log Valve

[Sinkinson,Andrew [NCR]]

If I log onto the server running my tomcat installation and perform an
nslookup on the ip that is sending the request it resolves.  Running
tomcat 5.0.27 as a service.

Just one -- perhaps the IPs in question do not resolve to hostnames.

Put another way, those IPs may not be resolvable from the Tomcat host.

Probably a URL encoding problem -- if a web page includes

  

then the browser will ask for "test .gif", because "test+.gif" is one of
the ways to encode "test .gif" so it's a legal URL.  (The other is
"test%20.gif".)

Whatever code is generating 

  

is wrong -- it should be

  

which the browser will decode to "test+.gif".

On tomcat index.jsp click on status.  To login you must create a user with

Tomcat 4.1.29 - Special chars in a file name

[Surendra Kumar]

Hi
   I am using Tomcat 4.1.29 + Apache 1.3.31.  In one of my webapp i have a file named 
"test+.gif"
   When i try to access this gif file, tomcat throws "resource not available message". 
All other gif files in the same
   dir are accessible. Even the directory listing shows the file is available. But 
when i select that file it's failing.
   I have tried encoding the url also, but it not working .

Does any one know how to access this file ?

Thanks
Surendra

LOL that's the proof that someone still writes on COBOL. 
seriously, using "Converters" or interpreters is a risky business when 
you're trying to implement something so tightly tied to a language like 
JSP or Servlets, factor that magnifies when you're writing mission 
critical apps (as i can guess from you writing on cobol, you're trying

Hi Mike,

Some thoughts.  If anyone sees errors please let me know - 
it may save me time in the long run!

If I recall correctly, the CGI approach throws everything
away after each request.  I moved from Perl CGI to Java 
Servlets a few years back partly to make use of the
load-once-then
-reuse aspect.  I think there was Mod Perl or something 
that sort of did this with Perl.

Any road up, you may find that that is why the CGI version
worked.  Maybe it was freeing/releasing things when the 
CGI script/prog finished each request.  You got a virgin
state every time.

Are you sure the disconnect all is being fired when
you think it is?

Also, is there any chance the the disconnect all is
freeing something you later depend on in subsequent 
requests?  For example, do you have an init() method
in your servlet that (initially) creates/connects,
and the doGet/doPost then uses the connection?

If this is the case, check the disconnect all is not
closing/nullifying the connections since the init()
won't get fired again.  This might explain why the CGI
implementation did make it through.

I don't know for sure - but it sounds like the sort
of right-of-passage problem most of us have had when
first starting with servlets.

I'd recommend gratuitous use of;

System.err.println( "Now executing {your method name}
");

then stare at the console window for Tomcat to see what's being
executed.  It's always my last port of call for this sort of
thing.

I use connection pooling on my intranet site which has 
low traffic but large/complex applications on the server.

I use it for two reasons;

a) It shifts some of the work to a thirdparty 
   bunch of code that I didn't have to write
b) Saves time on the creation/connection cycle
   for DB-centric applications.

Code-generation tools come with their own quirks and headaches.

Aside from that, you'd do well to get some serious Java study time or,
barring that, work with an experienced Java architect/developer who can
guide you through a project or two.

Problem setting custom Policy object in ServletContextListener

[william]

Basically, I am trying to install a custom Policy class on a web app running
within a Tomcat 4.1.27 container.
To do so, I have registered a ServletContextListener in the web.xml and I am
calling Policy.setPolicy(new rbac.MyPolicy()) from within the
contextInitialized method. Later I use the standard JAAS calls to check
permissions.

Everything works well on an XP tomcat installation. However, as soon as I
deploy to Solaris 2.8, strange behavior appears. It seems that the Policy
class is being modified so that the following calls made from a jsp

<% Policy.getPolicy() instanceof rbac.MyPolicy %> <%
Policy.getPolicy().getClass().getName().equals("rbac.MyPolicy") %>

return inconsistent values. The first returns false while the second returns
true!

If I delay the policy installation to a later point in the application
lifecycle (i.e. call setPolicy from within a servlet filter instead of
setting the Policy, the problem disappears. However, I would like to avoid
the extra overhead of filtering each request.

I am not running tomcat with the security manager. 
I would be grateful to anyone offering a remedy or suggestions.

Thanks,
// William.

[Michael McQuade]

Please forgive me,  I dont even understand a lot of these responses,   Im a
mainframe Cobol coder here,   not a Java person,  but Im using a Converter
that converts Cobol to Java Anyways,  I am pretty sure it has to be
Tomcat doing this,  because my Application ran just fine,   using MySQL,
and JDBC driver in a Web Server called OmniCron  in CGI format.
The only thing different now is,  Im trying to run SERVLETS using
Apache/Tomcat.  At the Start of  each Servlet I do  a connect to
database
CONNECT TO 'jdbc:mysql://127.0.0.1:3306/Imagescan'

DRIVER 'com.mysql.jdbc.Driver'

Then do my processing and then do a DISCONNECT ALL..

It just does not make sense I can connect ONE TIME only when running a
Servlet and have to back out of app,  STOP,  START,  and go back in,   to
get another one time connection.the 08002, connection name in use,
to me,   points to Tomcat ..

But as I said,  Im just a baby in diapers to this world..  I believe its
something in one of the .xml files,   but I have no idea.

As for Connection Pooling,is that for a system taking large numbers of
hits on it?  Right now, Im just one guy trying to make one connection
work.

Thank you for being patient.

Mike

I use a ServletContextListener for this. It has a 'static long startTime =

AW: Problem with session counting

[Michael Sudkamp]

Before calling session.invalidate() I now interrupt the thread which causes a database 
rollback. Now my JMeter-Tests run fine.

When the session times out, the DB cleanup is done in a valueUnbound() method of an 
appropriate session object.
