Re: where to store user-generated files?

[John Pedersen]

Looks like roll your own then!

A few thoughts on the matter - maybe someone could add to them?

It should be easy to map requests for images to a servlet, which can
then find the appropriate image file wherever it might be ( within or
outside the server ). Like this in the web.xml file:

servlet-mapping
servlet-nameservletName/servlet-name
url-pattern*.jpg/url-pattern
/servlet-mapping

?

But how is the image then added to the reponse? Another servlet (
behind the scenes - I am actually using  the Spring framework ) is
handling the request/response. Can the request/response be passed to
the image-providing servlet for the images within a page to be written
to the reponse in this kind of way:

// This method is called by the servlet container to process a GET request.
   public void doGet(HttpServletRequest req, HttpServletResponse
resp) throws IOException {
   // Get the absolute path of the image
   ServletContext sc = getServletContext();
   String filename = sc.getRealPath(image.gif);

   // Get the MIME type of the image
   String mimeType = sc.getMimeType(filename);
   if (mimeType == null) {
   sc.log(Could not get MIME type of +filename);
   resp.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
   return;
   }

   // Set content type
   resp.setContentType(mimeType);

   // Set content size
   File file = new File(filename);
   resp.setContentLength((int)file.length());

   // Open the file and output streams
   FileInputStream in = new FileInputStream(file);
   OutputStream out = resp.getOutputStream();

   // Copy the contents of the file to the output stream
   byte[] buf = new byte[1024];
   int count = 0;
   while ((count = in.read(buf)) = 0) {
   out.write(buf, 0, count);
   }
   in.close();
   out.close();
   }

( from http://www.exampledepot.com/egs/javax.servlet/GetImage.html )

I'm off for a walk to mull it over - any suggestions while I am out
and before I get to experimenting will be most welcome.

Thanks,

John

Re: [OT] RE: Found a product for running Tomcat off CDROM -have anybody tried it?

[David Wishnie]

Hello,


According to this page (select Tomcat in the left pane):
 http://stunnix.com/ws-ui-saws/ui.xpl/1/project.showprops
Tomcat seems to be 5.5.20 but here they state that one can add support for
any version of Tomcat to it (here:
http://stunnix.com/prod/aws/tomcat-cdrom.shtml )

As for use of MySQL w/JDK - I got the impression that it can't do this.
But I guess you'll have to contact them directly - probably they'll add
support for it if you'll ask.

Specifying -Djava.library.path when tomcat is running as a service

[Sriram Saroop]

Hi,
I am running tomcat 4.1.34 as a Windows Service by using service.bat
My application uses JNI and the required libraries exist in 3 folders:
C:\f1,C:\f2,C:\f3
When I add the these folders in -Djava.library.path:
%EXECUTABLE% //US//%SERVICE_NAME% ++JvmOptions -Djava.library.path=C:\f1
%EXECUTABLE% //US//%SERVICE_NAME% ++JvmOptions -Djava.library.path=C:\f2
%EXECUTABLE% //US//%SERVICE_NAME% ++JvmOptions -Djava.library.path=C:\f3

Only the last line seems to be effective. (Meaning f1,f2 are NOT in
java.library.path).
Also I cannot seem to specify :
%EXECUTABLE% //US//%SERVICE_NAME% ++JvmOptions
-Djava.library.path=C:\f1;C:\f2;C:\f3
since tomcat fails to start. I guess this is because ; is a separator for
the -D/-X options.

Other than merging the 3 folders, is it possible to specify multiple
directories as a part of -Djava.library.path ?

Regards,
Sriram

Hi

I understood that the sessions were of each user. isn't it?
I understood that One session to one Navegator to one user. isn't it?

I don't understand because the parameter can be overwritten by the value from 
another request. The object request is not part of the session?

 I pass an parameter to identify the type user. With this 
 parameter, i define if show one page.. or other. Some times 
 the parameter requested, was changed.

Do you ever store the parameter in some place that's not specific to the
particular Request object currently being processsed?  For example, if
you store the parameter in the Session or in some static variable, it
can be overwritten by the value from another request.

RE: overlapped parameters between sessions

[Caldarale, Charles R]

 From: WILLIAM PARRA [mailto:[EMAIL PROTECTED] 
 Subject: Re: overlapped parameters between sessions
 
 I understood that the sessions were of each user. isn't it?

There may be multiple sessions per user, depending on the browser,
number of windows open, etc.

 I understood that One session to one Navegator to one user. isn't it?

Not necessarily; there may be more than one session.  A session will not
be shared by multiple clients, but it can be shared by multiple tabs or
browser windows opened by a single client.

 I don't understand because the parameter can be overwritten 
 by the value from another request. The object request is not 
 part of the session?

No, it is not part of the session.  A browser often submits multiple
requests simultaneously, resulting in multiple threads within Tomcat
utilizing the same Session object at the same time.  Any synchronization
of access to the Session object is the responsibility of the app.  The
same is true for any fields of your servlet objects.

RE: where to store user-generated files?

[Williams, Allen]

I'm new at this, so bear with me here for a moment...

The servlet mapping seems to me to tell tomcat anytime you have a
request for a URI with .jpg extension, deliver the request to this
servlet, but that doesn't give any information about where in the
real file system said jpeg is stored, does it?  So, when you call
sc.getRealPath(), how does the servlet context know where to go?
Doesn't there have to be a mapping or alias somewhere (server.xml,
web.xml,...?) that resolves, or translates ThisTypeofFileName.ext into
/real/path/in/OS/ThatTypeOfFileName.oxt?

It should be easy to map requests for images to a servlet, which can

But how is the image then added to the reponse? Another servlet (
behind the scenes - I am actually using  the Spring framework ) is
handling the request/response. Can the request/response be passed to
the image-providing servlet for the images within a page to be written
to the reponse in this kind of way:

 // This method is called by the servlet container to process a GET
request.
public void doGet(HttpServletRequest req, HttpServletResponse
resp) throws IOException {
// Get the absolute path of the image
ServletContext sc = getServletContext();
String filename = sc.getRealPath(image.gif);

// Get the MIME type of the image

 Doesn't there have to be a mapping or alias somewhere (server.xml,

Yes.  Normally, such static content is handled by Tomcat's
DefaultServlet, and the file system mapping must correspond to the URI
path.  In this case, a servlet of your app will be handling the request,
and it's up to your app to implement whatever mapping you desire.

Re: Expression Language in JSP and JasperException

[Piotr Kiraga]

Hi David,


Ok  forgive me now, but this is getting confusing.  Where does
result come into this picture?  Were you expecting actionBean to be an
instance of a different class?  You aren't offering a lot to go on here.


Sorry for mixup. I've just thought that it is just about some option
in Tomcat configuration or something, and I haven't knew it. Like I
see... It may be not. :(

Here goes more background.

login.jsp (handled by LoginActionBean class) redirects after
submission login form to calculator.jsp. After submition form from
calculator.jsp  (what is handled by CalculatorActionBean class) it
returns to calculator.jsp and shows the result of mathematical
equation. Sources of calculator.jsp and it's class are placed below.

Problem shows when I'm submiting from LoginActionVean to
calculator.jsp. Like I wrote before, LoginActionBean doesn't have
result field because it doesn't need it. But JSP (in this case used by
two classes) expects result in:
46:c:if test=${!empty actionBean.result}
47:Result: ${actionBean.result}br/
line.

Here actionBean could be an instance of different class.

Sorry for so much source in thread, here it goes:

Re: XML parser issue while defining a Realm

[David Delbecq]

Hi

1) This is not an ldap or filter error, this is an xml wellformness
error. That mean tomcat can not parse your xml file
2) You say you can cut and paste it inside and ldap browser and it work?
Are you sure it is amp; that is inside your search rule? I mean your
ldap browser most probably do not parse xml entities, and as such, you
must probably feed it with '' instead of 'amp;' So check you have
correctly, in your xml, all '' replaces by 'amp;'
3) Send us you xml file as attachement if it still does not work :)

Posting Xml

[Dima Retov]

Hello,

Is that good idea to POST XML data to Tomcat?

I wish to make HTTP request to servlet in Tomcat.

Method POST
Content Type: text/xml

Content would be non encoded XML file.

Is it good idea in general. My tomcat handles such requests now.
Is it expected that it will work in future?

Is there any limitations? e.g. request.getParameter() - should
parse GET parameters only.

RE: where to store user-generated files?

[Williams, Allen]

Gotcha.  So, servlets can access the file system just like any other
java or C++ program?  I was thinking they were restricted, but now that
I'm thinking about it I think I was confusing that with applets.  If
tomcat is running as user tomcat55, do the servlets run as the same
user, so you can set file permissions up with something like rwx--
(700) if you make the directory owned by tomcat55?

Re: where to store user-generated files?

[David Smith]

I'm sure this is horribly insufficient, so I would recommend reading the
servlet spec.  It's not all that bad a read as far as specifications go
and you can learn a lot about how tomcat operates.

If you have a servlet mapping all *.jpg to some servlet myServlet in
web.xml, web.xml also has another section where the servlets are
individually declared.  In there you'll find the class that backs the
servlet named myServlet.  All that means is the request for the
resource goes to that specific servlet class to be handled.  What the
servlet does with it is open-ended.  In the case of the default servlet,
it basically calls sc.getResourceAsStream( request.getServletPath() +
request.getPathInfo() ) and returns the contents of the file to the
client.  That's over simplified -- the real default servlet does some
security checks to be sure it's not returning something it shouldn't and
set's the mime type in the response, but you get the idea. 
sc.getResourceAsStream is aware of the webapp's location in the
filesystem and takes care of finding the resource in the webapp's folder.

sc.getRealPath will only return a full path to a file if the webapp is
NOT compressed in a web archive file (.war).  From within a .war file,
it always returns null and isn't recommended except in rare cases where
you might want to write access.  This is all in the spec.

Servlet 2.4 spec is available at
http://jcp.org/aboutJava/communityprocess/final/jsr154/index.html

I'm new at this, so bear with me here for a moment...

The servlet mapping seems to me to tell tomcat anytime you have a
request for a URI with .jpg extension, deliver the request to this
servlet, but that doesn't give any information about where in the
real file system said jpeg is stored, does it?  So, when you call
sc.getRealPath(), how does the servlet context know where to go?

Subject: Re: where to store user-generated files?

Looks like roll your own then!

A few thoughts on the matter - maybe someone could add to them?

It should be easy to map requests for images to a servlet, which can
then find the appropriate image file wherever it might be ( within or
outside the server ). Like this in the web.xml file:

servlet-mapping
   servlet-nameservletName/servlet-name
   url-pattern*.jpg/url-pattern
/servlet-mapping

?

But how is the image then added to the reponse? Another servlet (
behind the scenes - I am actually using  the Spring framework ) is
handling the request/response. Can the request/response be passed to
the image-providing servlet for the images within a page to be written
to the reponse in this kind of way:

 // This method is called by the servlet container to process a GET
request.
public void doGet(HttpServletRequest req, HttpServletResponse
resp) throws IOException {
// Get the absolute path of the image
ServletContext sc = getServletContext();
String filename = sc.getRealPath(image.gif);

// Get the MIME type of the image
String mimeType = sc.getMimeType(filename);
if (mimeType == null) {
sc.log(Could not get MIME type of +filename);
 
resp.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
return;
}

// Set content type
resp.setContentType(mimeType);

// Set content size
File file = new File(filename);
resp.setContentLength((int)file.length());

// Open the file and output streams
FileInputStream in = new FileInputStream(file);
OutputStream out = resp.getOutputStream();

// Copy the contents of the file to the output stream
byte[] buf = new byte[1024];
int count = 0;
while ((count = in.read(buf)) = 0) {
out.write(buf, 0, count);
}
in.close();
out.close();
}

I'm off for a walk to mull it over - any suggestions while I am out

For 

Tomcat/mod_jk/Apache - up to date - matching versions?

[Sharon French]

We are configuring a new server for use in a production environment, we
would like to maintain a similar setup to our other servers (apache + mod_jk
+ tomcat) but would like to upgrade to the latest appropriate versions.

We are running on Red Hat Linux (kernel 2.6.9-5) with the 1.5.0_11 JVM -
looking around, I believe that the latest stable versions are:
apache: 2.2.4
mod_jk: 1.2.20
tomcat: 5.5.20

My understanding is that within reason the versions of tomcat/mod_jk/apache
don't need to match, but I wonder if there are any version combinations
that would best be avoided? Or conversely, a combination that is
particularly useful?

Anyone care to convince me that the above aren't the versions I ought to be
using?

Thank you in advance for any input,

but tomcat threw exceptions. If you know a way, could you help ?

80 is a privileged port on *nix systems, you'll need to run tomcat as root
(generally not recommended). May I ask why you're still running tomcat circa
version 3?

RE: Connection pool problem DBCP - 4.1.3

[Propes, Barry L [GCG-NAOT]]

I wonder...would I get mixed results trying to implement JNDI maing in my 
server.xml file, but only trying to (on a page by page basis, with an existing 
servlet and/or JSP) utilize the naming context method?

In other words, I test out DBCP with one dedicated servlet or JSP, and perhaps 
it works fine, but somehow that adversely affects another servlet or JSP where 
I've not really implemented the Naming Context portion, but since I've altered 
the server.xml file, that's affected it?

Please let me know if you have any insight into this.

This is driving me crazy. I'm finally close, I think, on getting this

Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup(java:comp/env); // Look up

// Allocate and use a connection from the pool Connection connection =

 PHONE_NUM,DATE_REQ,...  +
   +
 FROM table a INNER JOIN table b  +
 ON a.CTRL_ID = b.CTRL_ID  +
 WHERE AID = ?;

PreparedStatement prepstmt = connection.prepareStatement(prepSQL);
prepstmt.setString(1, aidstrd);
ResultSet admsql = prepstmt.executeQuery(); admsql.next();

(etc., etc.)

admsql.close();
selstmt.close();
connection.close();

If I move up connection.close, I get the Connection is closed statement,
otherwise I get exhausted result set. 
Any idea what gives?

Re: Expression Language in JSP and JasperException

[David Smith]

Ok.  I'm not overly familiar with Stripes, so you'll have to bear with
me a little.  I can think of a few ways to handle this.

First, look at what makes a request from calculator.jsp unique.  You
could use the referrer header, the value of a submit button, or the
presence of the equation request parameter.  Below is an example using
the submit button:

c:if test=${(param.submitBtn == 'Calculate') and (actionBean.result !=
null)}
  pThe answer is ${actionBean.result}/p
/c:if

A better solution would be to name the actionBean that's a result of
CalculatorActionBean something more descript than just 'actionBean' like
'calcBean'.  The main advantage here is it's simple and you could use
your original expression language test -- just change the name of the
object being tested:

c:if test=${calcBean.result != null}
  ... display the result
/c:if

A more complicated solution if you can't change the name of 'actionBean'
might be to test the type of actionBean like...

c:set var=calcAvailablejsp:expression
  (request.getAttribute(actionBean) != null) 
(request.getAttribute(actionBean) instanceOf
com.some.packages.action.CalculatorActionBean )/jsp:expression/c:set
c:choose
c:when test=${calcAvailable and (actionBean.result != null)}
  pThe answer is  ${actionBean.result}/p

The essential point of this is testing for a property to be null is not

property before you can test the property for null.

 Hi David,

 Ok  forgive me now, but this is getting confusing.  Where does
 result come into this picture?  Were you expecting actionBean to be an
 instance of a different class?  You aren't offering a lot to go on here.


 Sorry for mixup. I've just thought that it is just about some option
 in Tomcat configuration or something, and I haven't knew it. Like I
 see... It may be not. :(

 Here goes more background.

 login.jsp (handled by LoginActionBean class) redirects after
 submission login form to calculator.jsp. After submition form from
 calculator.jsp  (what is handled by CalculatorActionBean class) it
 returns to calculator.jsp and shows the result of mathematical
 equation. Sources of calculator.jsp and it's class are placed below.

 Problem shows when I'm submiting from LoginActionVean to
 calculator.jsp. Like I wrote before, LoginActionBean doesn't have
 result field because it doesn't need it. But JSP (in this case used by
 two classes) expects result in:
 46:c:if test=${!empty actionBean.result}
 47:Result: ${actionBean.result}br/
 line.

 Here actionBean could be an instance of different class.

 Sorry for so much source in thread, here it goes:

Re: Get rid of 8080 port in Tomcat 3.3

[David Smith]

I haven't tried it on such an old version of tomcat, but I would think
jsvc from the commons-daemon project would work here.

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

It essentially allows you to start tomcat as a privileged user long
enough to grab the port and then drop back to a low privilege user for
general running.

Re: Posting Xml

[David Delbecq]

Hi,
tomcat does not care what is in the body of request, it just look at url
to map it to a servlet and headers to create context and request
objects. The rest is entierly up to servlet to manager.

For your information, slide is a webdav servlet working under any J2EE
compliant webapp container that handles xml request from clients, and
there are also lots of webservices servlets around that take requests in
xml form

 Hello,

 Is that good idea to POST XML data to Tomcat?

 I wish to make HTTP request to servlet in Tomcat.

 Method POST
 Content Type: text/xml

 Content would be non encoded XML file.

 Is it good idea in general. My tomcat handles such requests now.
 Is it expected that it will work in future?

 Is there any limitations? e.g. request.getParameter() - should
 parse GET parameters only.

Re: where to store user-generated files?

[John Pedersen]

I have something that works:

in web.xml:

servlet
servlet-nameimageServlet/servlet-name
servlet-classImageServlet/servlet-class
load-on-startup2/load-on-startup
/servlet

servlet-mapping
servlet-nameimageServlet/servlet-name
url-pattern/users/image/*/url-pattern
/servlet-mapping

Links to user images are like this:

img src=/starfriend/users/image/${match.thumbName}

( I am using Velocity )

and this is the servlet:

public class ImageServlet extends HttpServlet {

public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws IOException {

   String path = PhotoHandler.getUserImageDirectory();  
String pathInfo = req.getPathInfo();
String fileName = path + pathInfo;

   // Set content type
resp.setContentType(jpg);

// Set content size
File file = new File(fileName);
resp.setContentLength((int) file.length());
resp.setContentType(image/jpeg);

// Open the file and output streams
FileInputStream in = new FileInputStream(file);
OutputStream out = resp.getOutputStream();

// Copy the contents of the file to the output stream
FileCopyUtils.copy(in, out);
}

}

Image directory path is held in a properties file, which is held in
memory by a class called PhotoHandler - that is just the way I have it
- of course the path to the image folder could be an init parameter of
the servlet.

RE: Connection Pooling Question

 -Original Message-
 From: Marc Farrow [mailto:[EMAIL PROTECTED]
 Sent: Monday, February 19, 2007 3:56 PM
 To: tomcat-users
 Subject: Connection Pooling Question
 
 Slightly off topic, but the core of what I want is being done in the
 source
 code of Tomcat. I am trying to use the Apache Commons DBCP classes to
 create
 my own connection pooling factory that I can use within my servlet
 container
 (Tomcat) and also in stand alone programs.  I see how the Datasource that
 Tomcat creates when you use its connection pooling is put into a JNDI
 context, but I have scoured over the Tomcat source code and I have not
 been
 able to find the code that is actually doing the context bindings and
 where
 the information is being held.  Can someone point me in the right

I have done something similar, which may be helpful or of interest to you.
For our unit tests, I have used the standard JNDI jars from Tomcat
(naming-factory, naming-factory-dbcp, naming-resources) and in the
BaseTestCase (extends junit.framework.TestCase) I create and load the JNDI
context from a property file.

This allows the rest of the classes-under-test to function as if they were
running under the Tomcat container and allows for the regular and complete
JNDI lookup of all our DataSources.  I used to use the JavaRanch jndi helper
but it only supports a single DataSource.

I would be happy to share the code with anyone who may want it.  It's 200+
lines of code, and I wouldn't post the whole thing to the list, so send me
e-mail off-list if you want a copy.

 direction
 of the source code to review and also any advanced JNDI tutorials that
 teach you how to bind to a context that can be reused by external
 resources
 (meaning another JVM).

For one JVM to see or provide JNDI lookups for another would require a
network/port aware JNDI scheme.  I'm not aware of one, but wouldn't be
surprised if one exists either.

 
 Also, has anyone seen or done this type of solution before?
 
 Thank you,

Compiling mod-jk plugin for SunOne on Solaris

[Kirk]

There was a thread from February 1st on this same issue.  I am having the
same problem that person did, but I tried everything in the thread and still
no luck.

After I get mod_jk compiled I get this on server startup:

failure: CORE3170: Configuration initialization failed: Error running
init function load-modules:
dlopen of /wamu/hr/sunone/plugins/mod_jk/nsapi_redirector.so failed
(ld.so.1: webservd: fatal:
relocation error: file
/wamu/hr/sunone/plugins/mod_jk/nsapi_redirector.so: symbol __lshrdi3:
referenced symbol not found)


The one thing that I think is making a difference as compared to the person
in the earlier thread is that gcc is not installed on the server I am trying
to deploy on and I am not allowed to have it on there.  it is not an option,
don't ask.  I tried static linking, but I have a feeling I am doing it
wrong.

So, my question is, what exactly do I need to do to compile the mod_jk
plugin for SunOne on Solaris where it is to be deployed on a server that
does not have gcc installed at all?

Thanks,
Kirk

authentication security constraint error

[Propes, Barry L [GCG-NAOT]]

Hi,
 
I've been using versions 4.0 and 4.1.3 with a security constraint with no 
problems.
 
However, when I added info in my server.xml file to try and attempt DBCP, I get 
a warning in my logs about something being defined in in an auth-constraint 
without being in a security role. Maybe not too big a deal.
 
However, ever since I added the Resource Name and Params for the DBCP, I don't 
get challenged on the form to enter the password protected area, which in 
turn causes some other errors.
 
Does anyone know why adding that bit of configuration to the server.xml file 
would render the security constraint inoperable?
 
I'm open to feedback, let me know if more info's needed.
 
Thanks!

 
 
 
I've actually got the security constraint configured properly, as it's worked 
before with no issues.:

Re: Compiling mod-jk plugin for SunOne on Solaris

[Rainer Jung]

Option 1) (Quick and dirty): Deploy libgcc_s.so. It's *not* the
compiler. The lib contains some machine specific runtime routines, for
which appropriate machine statements are not available.

Option 2): Compiling statically. If you've got good control over the
compilation process you can add -static-libgcc to gcc as flags. If you
don't want to find out, where all the gcc compile flags are coming from
(configure, environment variables etc.) you can decide to make all
compiles using static libgcc by hacking a specs file.

a) dump a specs file by calling gcc -dumpspecs.

b) Edit the results and throw everything away except the block
beginneing with *libgcc. The exact structure depends on the gcc
version. Here is an example:

*libgcc:
%{static|static-libgcc:-lgcc
-lgcc_eh}%{!static:%{!static-libgcc:%{!shared:%{!shared-libgcc:-lgcc
-lgcc_eh}%{shared-libgcc:-lgcc_s -lgcc}}%{shared:-lgcc_s}}}

Caution: this is only two lines, the second one is pretty long.

Now edit to make gcc link against libgcc (this is the static version)
instead of libgcc_s (the shared one) even if it has been called to
produce a shared object. In our example the result would be:

%{static|static-libgcc:-lgcc
-lgcc_eh}%{!static:%{!static-libgcc:%{!shared:%{!shared-libgcc:-lgcc
-lgcc_eh}%{shared-libgcc:-lgcc -lgcc_eh}}%{shared:-lgcc -lgcc_eh}}}

Save this file, e.g. as /my/gcc.specs.

Then set the environment variable CC to gcc -specs=/my/gcc.specs and
start building. You can check the library dependencies of the resulting
*.so file by using ldd.

Good luck.

Regards,

Rainer

RE: Get rid of 8080 port in Tomcat 3.3

[Steffen Heil]

Hi

 That's the way You should go:
 http://www.linux.org.mt/article/tomcat-ports

I totally disagree.
First, it would surely be best to update to 6.0 and run it using jsvc

However, let's look at the solution in the link above.

1. The Apache solution. (Which should be called the httpd solution.)
This will work, and might be okay, if you are already running apache on that
system.
BUT tomcat itself can be faster (at least newer ones, I don't know about
3.x) without httpd.

2. The IP tables solution
You webapplication will not know about the different port and encode urls
incorrecly. Bad Idea and impossible if SSL is required.

3. The rinetd solution
Good for development and tests. Adds a little overhead AND destroy a lot of
logging and security, as tomcat will always see ONE client ip.

4. IPchains alternative
see 2.

UPGRADE.
Otherwise get jsvc to work for you.

Regards,
  Steffen

 Yeah, I had them in there.

Are they in the right order relative to the other elements?  The
web-app schema is rather picky about how things are arranged.  The
web.xml files for Tomcat's manager and admin apps server as good
examples.

RE: JVM per web App in Tomcat 5 possiable

[Caldarale, Charles R]

 From: jerrythenoob [mailto:[EMAIL PROTECTED] 
 Subject: JVM per web App in Tomcat 5 possiable
 
 my application uses a thrid-party native lib which will
 bring down tomcat if the internet connectivity is lost
 after a couple of attempts.

Hope you didn't pay money for that.

 Is there a way to start another JVM for that web app alone ?

You can run multiple Tomcat instances on the same box, but each will
require its own unique IP-address/port combination.  See the Advanced
Configuration section of RUNNING.txt in your Tomcat home directory for
details.

If you need to run multiple instances all with the same IP address and
port, you'll need something in front of them to dispatch requests to the
proper instance.  Apache httpd can do this, for example.

RE: JVM per web App in Tomcat 5 possiable

[Rutherford, Michael]

I had a similar problem (native exceptions propagating out and killing
the JVM and thereby Tomcat). My quick and dirty solution was to wrap the
calls with a main() and run them as a separate java app in its own JVM.
Any problems therefore killed the subordinate JVM not the one running
Tomcat.

I'm sure there are better ways but I haven't had the luxury of time to
re-address this yet.

RE: Maximum single threaded moldel servlets

[Caldarale, Charles R]

 From: James McIntosh [mailto:[EMAIL PROTECTED] 
 Subject: Maximum single threaded moldel servlets
 
 I am trying to find out how to limit the number of 
 Single Threaded Model servlets which get created by
 the StandardWrapper.

I suspect there's not much interest in this aspect of the servlet
environment these days, considering the following quote from section
2.2.1 of the 2.4 servlet spec:

The SingleThreadModel Interface is deprecated in this version of the
specification.

I don't know when it became deprecated, but it strikes me as a bit risky
to base an application architecture on such a capability.

System property use in web.xml?

[Martin . X . Zaidel]

I've inherited a webapp which includes a system property reference (ie., 
region) in its web.xml (BTW, this context-param is used to lookup a 
Spring context file---e.g. /WEB-INF/jmsContext-eur.xml)

context-param
param-namecontextConfigLocation/param-name
param-value
/WEB-INF/jmsContext-${region}.xml,
/param-value
/context-param

When I deploy this webapp to Tomcat 5.5.12, and define a command-line 
system property with '-Dregion=eur' in catalina.sh, it works fine: the 
jmsContext-eur.xml file is found.

However, when I try to deploy this webapp to Websphere 6.0.x, even after 
defining a custom property for 'region' in the server profile, I get a:

java.io.FileNotFoundException: /WEB-INF/jmsContext-${region}.xml,

 when the server starts.

While my immediate problem is how to deploy the webapp to Websphere, my 
question to this group is this: Which component is responsible for this 
behaviour (the parsing of the web deployment descriptor and the 
substitution of the system property)?  Is it expected J2EE 1.4 
behaviour---ie., something I can complain to IBM about?

Thanks,

Martin

Mysql timouts...

[Jacob Rhoden]

I am having the seemingly common Broken pipe to mysql problem with 
tomcat.


All i could find was some info about a maxideltime setting and 
idleconnectiontestperiod where can I find out info about tuning to 
make sure tomcat doesn't serve out stale database connections? The 
following settings don't seem to be doing the trick:


 Resource auth=Container name=jdbc/blah type=javax.sql.DataSource
 maxActive=5 removeAbandoned=true
 maxIdle=2 maxIdleTime=300 idleConnectionTestPeriod=60
 maxWait=1 username=blah password=blah
 driverClassName=com.mysql.jdbc.Driver 
url=jdbc:mysql://localhost:3306/blah?autoReconnect=trueamp;useUnicode=trueamp;characterEncoding=utf8/



Thanks guys.

I'm afraid that system property substitution is a Tomcat-specific feature. 
You can't rely on it working in any other Servlet Container.

 Subject: Pls help : How to make case insensitive URL(JSP) on

Read the doc:
http://tomcat.apache.org/tomcat-5.5-doc/config/context.html

caseSensitive

If the value of this flag is true, all case sensitivity checks will be
disabled. If not specified, the default value of the flag is true.

NOTE: This flag MUST NOT be set to false on the Windows platform (or
any other OS which does not have a case sensitive filesystem), as it
will disable case sensitivity checks, allowing JSP source code
disclosure, among other security problems.

It's strongly recommended that you teach your users to type, since
case-sensitivity is mandated by the URI Generic Syntax document (RFC
3986) and the servlet spec.
