removal of product name/version

[Tommy Pham]

Hi,

I'm looking for a way to remove the product name and/or version from the server 
header and default http errors (without defining my own custom error-page).  I 
know it's possible for apache using ServerSignature and ServerTokens, also 
possible for glassfish v2 using a jvm option.  I've looked at the 
tomcat.apache.org's docs and can't seem to find anything close it.  Would 
someone please point me in the right direction?

TIA,
Tommy

 If you mean the pages displayed to the client during an
 error condition,
 then you must define your own error-pages. These default
 ones are, IIRC,
 hard-coded into Tomcat.

Thanks all for the reply.  Somehow I missed that attribute.  Looks I'll have to 
define the error-pages.  If I specify in the web.xml in the conf folder, does 
apply to all web apps deployed for that host/virtual host?  And what happens if 
certain web apps define their own error-page in in it's own web.xml?  Does the 
web app's definition override the host/virtual host's?

Thanks,
Tommy

IMO if you want to use PHP with Tomcat, it's best you read the documentation 
for both products and their technology as it will help you secure the 
server/platform and troubleshoot any problems that may arise including 
application crashes and security breaches.
For PHP5: http://www.php.net/manual/en/
For Tomcat6: http://tomcat.apache.org/tomcat-6.0-doc/index.html
For Tomcat5.5: http://tomcat.apache.org/tomcat-5.5-doc/index.html

You can just go through the installation steps w/o doing the actual 
installation to see what you have available.  Though I haven't tried this 
method, I think you can run PHP as CGI in Tomcat.  You'll just have to edit the 
web.xml in $CATALINA_HOME/conf folder and follow PHP's instruction of 
installing as CGI.

The method I prefer and have tested to work (in Unix environment although on 
Windows should be similar) is running Apache HTTPD server with PHP as a mod and 
use the connector to connect to Tomcat.  If this method is used, it's easier to 
implement other technologies later such Perl, Python and Mono (for .Net) inside 
Apache HTTPD as mod-*.

But you may want to evaluate your needs and goals before choosing ;)

Tommy

Tomcat 6.0.18 JavaEE 5/EJB3.0

[Tommy Pham]

Hi,

I'm trying to develop a web app using JDK1.6 and Tomcat 6.0.18 and JPA.  When 
creating a new web app in Netbeans 6.1, I chose the Java EE 5 version.  Then I 
proceed to create Entity Classes from Databases which were successful.  If I 
try to create JSF pages from Entity Classes, I get:
The class javax.transaction.UserTransaction is unavailable. Add an appropriate 
jar file ...

After adding javaee.jar from Glassfish v2 into my web app and deployed the web 
app, I got this error:
INFO: Illegal access: this web application instance has been stopped already.  
Could not load java.lang.Object.  The eventual following stack trace is caused 
by an error thrown for debugging purposes as well as to attempt to terminate 
the thread which caused the illegal access, and has no functional impact.
java.lang.IllegalStateException
at 
org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1273)
at 
org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1233)

I think it's because of the javaee.jar causing conflict with tomcat's jar files.

I know that Tomcat is only a web container but is there a way I can implement 
JavaEE5/EJB3.0 for full Persistence support without having to switch to 
Geronimo 2.x or Glassfish v2/v3?  (I think this is a stupid question but I just 
want to know my options :) I rather not switch to Glassfish if I don't have to 
because of default directory browsing Glassfish has :D

Thanks,
Tommy

Persistence, I can make full use of transaction if any part of the inserts 
failed w/o having to worry much about incomplete/junk data in my db because

 Hi Tommy,
 
 That was really informative. But let me explain you the
 actual scenario. I
 am using an application called phpESP ( a survey tool
 developed in PHP) and
 running on Apache httpd. The application is running fine,
 but it is
 consuming lot of memory space in the server. So we have
 decided to move the
 application and deploy on a lighter application server.
 That's the reason we
 have decided to deploy on Tomcat. So could you please let
 me know your
 opinion on the same. 
 
 Also i am a beginner to PHP and Tomcat. Also i have spend
 lot of time on
 this and now i have to some how finish this task. Offline i
 will take your
 guidance on understanding this technology. For now could
 you please explain
 us with the step by step instruction on how to finish the
 same task.

Radhakrishnavangara,

If your app is pure PHP (and perhaps some Javascript/AJAX) and you have no 
intention of migrating to another platform, your best bet is sticking with 
Apache httpd and troubleshoot your performance issue.  Otherwise you're just 
making things more complicated.  As Alan pointed out, there downside to running 
PHP as CGI which you may want to consider is worth it to migrate to another 
platform server which has no main use for you?  If you do intend to migrate to 
another platform, then just follow as Johnny pointed out.

As for performance, rule which i go by is run lean meaning take out any httpd 
mods and any php extensions you have no use for (you will need to refer to 
Apache httpd's and PHP manual for this).  By removing unnecessary mods and 
extensions, you reduce the memory consumption.  Then start looking at your 
server/system for unnecessary processes/services (you'll have to refer to your 
OS documentation for this).  If it's still running slow, then you'll have to 
the dirty work of debugging and fine tuning your app (if you didn't build it, 
you may refer to developers/provider whom  build it for help) since the app you 
use may free the resources it consumes.  Thus, as time goes on, your server 
will be running slow.  This is a problem with all apps regardless of what 
server/platform the app running is on.  Some server/platform has some method of 
garbage collection but you'll need to read the server's/platform's 
documentation to know what you have to work with.

Tommy

Struts vs JSF (poll?)

[Tommy Pham]

Hi everyone,

This maybe out of scope for this list but I wanted to know more about Struts vs 
JSF other this old article [1].  Which are are deployed mostly on your TC 
server(s)/cluster(s)?  If any Java developers are on this list, which platform 
API do you prefer for quick development (to meet deadline), performance, 
security management (user authentication and level restriction) etc... since 
both are based on MVC despite their different implementations(?).

Since there isn't a JSR for Struts, has Struts been around before JCP is 
formed?  And why is there not a JSR for Struts now (just curious)?

As for JSF, which implementation is used by/for your app(s)? Sun/NetBeans? 
Apache's MyFaces? or Others (please list)?  I'm somewhat disappointed Netbeans 
support for JSF and Struts in that Netbeans bundled libs support used older 
Apache Commons lib version (even for the current v6.1), although this could be 
updated but I don't know whether it will break the integration of Netbeans' 
VWP.  Even the tutorial/trails on NetBeans site regarding Struts (although this 
can be compensated at Struts' web site) is very limited perhaps because of the 
(biased?) Struts weak integration to favor or push more on JSF/Visual JSF?

I need to evaluate my options of API and IDE before I dedicate several projects 
since the performance of Netbeans is getting worse by every release comparing 
to Eclipse.  As for server, I've decided already ;)

TIA,
Tommy

 allow from
 ip x to enter only section Y of the application .
 thanks
 

Hi Meir,

I think the only possible approach is within the application itself since you 
want to limit access to certain portions of the application.  You can use the 
request.getRemoteAddr() of the HttpServletRequest.  If you store the 
information (URL  IP) in the database, you can change it dynamically as you 
need to :).  Also, you can log for repeated attempts of hacking ;)

 Hello,
 
 I am trying to get Tomcat 6.0.18 to run on my Win2k3 x64
 edition server. I basically did the same thing talked about
 here:
 http://markmail.org/message/kptleixb6duxgwhm
 but it didn't work for me. I didn't use the
 service.bat install though. I installed the service manually
 with the sc.exe command.
 
 I am using the 64-bit 1.6.0_06 JDK.  I don't get any
 Windows errors, the service start process just times out. My
 catalina and jakarta logs don't have anything useful.
 The logs seem to indicate that Tomcat started up fine--only
 it didn't. 
 
 When I start up Tomcat from the command line, it works
 fine. I did have to check the box in tomcat6w.exe to allow
 the service to interact with the desktop to run it from the
 command line though. That seemed a little weird. 
 
 Anyone successful in running Tomcat 6 as a 64-bit service? 
 
 Thanks,
 Brian

Hi Brian,

Are you using the zip install or exe install? It's easier to use the exe 
install.  Then download these tomcat*.exe at [1] and replace the files in bin 
folder.  If you need bat script files, you can extract those from the zip.  I 
have it running fine on WinXP x64.

Tommy

 Thanks again..
 

Hi,

Since you're in the domain and if my memory serves correctly (it's been a while 
since I worked w/ windows domains), you'll need to have proper access rights to 
access the registry.  Not all WMI commands will work with User/Power User 
rights.  You'll need full Administrator's rights on the target system if you 
want to use WMI to it's fullest.  You may want to check your domain policy and 
the local systems' policy (if any is defined).  Logging into a machine does not 
mean that account have the appropriate access rights, especially if you're 
trying access HKLM, HKCR, and HKUSERS.  You may want to look into impersonation 
to lessen the security risk of unwanted full domain access ;)

Tomcat 6.0.16 serving 40K jpg files

[Tommy Pham]

Hi,

I just start learning Java programming a while back and doing some 
tutorials/learning trails at netbeans.org.  One of the tutorial using Visual 
JSF, http://www.netbeans.org/kb/60/web/fileupload.html, I'm doing is not 
working as I think it should and I'm not getting any http error or Java 
exception.  I can upload the image fine and it will display any jpg ~40k or 
less.  If the image size is larger, it doesn't show.  I tried to browse the 
40k+ image directly instead of the image tag, it doesn't show also.  Does 
anyone know why is this?  I tried google for problem but unable to find any.  
The development platform is WinXP x64 JDK6 1.6.0_06, Tomcat 6.0.16. The default 
installation configurations have not been modified.

TIA,
Tommy

It breaks down every component of the url (protocol, domain name, etc).  Is

 I know that when processing from Tomcat, I can do

 I'd like to

 Not really since I just need to process the query string
 portion to see 
 if a given param exists or not.  I'm using a simple
 homegrown parser now:
 
 public boolean isParamInUrl(String url, String
 paramName)
 {
 int pos = url.indexOf(?);
 if ( pos  0 )
 url = url.substring(pos);
 String[] paramValues =
 url.split();
 if ( paramValues == null )
 return false;

 for( String paramValue : paramValues )
 {
 String[] paramAndValue =
 paramValue.split(=);
 if ( paramAndValue == null ||
 paramAndValue.length != 2 )
 return false;
 if ( paramAndValue[0].equals(paramName) )
 return true;
 }
 return false;
 }
 
 The concern is whether this is valid should the URL have
 complex params 
 and such based on encoding schemes.  I mean, it just splits
 the url 
 query string into an array of param-values '',
 and then splits that by 
 '=' without concern for any encoding.

Hi,

Wouldn't be faster/less coding if you just use this?

URL aURL = new URL(url);
String urlParams = aURL.getQuery();
if (urlParams.contains(paramName)) {
// proccess as needed if paramName exists
} else {
// process as otherwise
}

just a thought :)

such as NetBeans and Eclipse does it for you automatically.  I don't remember 
if NetBeans actually make a war or not but it does autodeploy.  Eclipse will 
auto synchronize and sometimes it will auto-redeploy the app or restart TC 
depending on what was changed.  What IDE are you using?  If you're referring to 
production, isn't a bit a dangerous/risky to be doing changes as you mention?  
Production should be touched after thorough testing of the app on development 
server, correct me if I'm wrong.

Regards,
Tommy

  
 Is there a common way to do this?

 Hello. My next trouble. 
 Periodically, the body disappears POST-request with the same query! 
 I wrote a test client. It httpClient sends a test request, and on the server 
 side, the servlet it takes. And trying to read.
 Sometimes there is a situation that the titles are coming, but the body is 
 absent. 
 That is, when reading req.getInputStream (). Read (...) we obtain -1. 
 This error appears periodically. Tested on JBoss-4.2.2.GA with Tomcat 5.5.X. 
 Please, help me!

From my readings, I remember that the servlet doesn't handle POST by default.  
So you have to implement your own.  I've looked into options available and the 
best I could find, IMHO,  and others have suggested is Commons FileUpload.  It 
will handle all POST multipart, including the file upload.  Look into the 
Streams API.

 Servlets handle uri encoded POSTs just fine.  It's when the POST body is
 encoded differently like with mulipart -- that's where tools like
 fileupload come into the picture.  Either way, the POST body should be
 completely available to the servlet, even if it's just as an input stream. 
 
 Were there any exceptions in the logs for broken pipes or similar stuff
 that might shed some light on the issue?

Eugene,

Is the POST URI or multipart encoded?  You didn't mention it and I forgot to 
ask you.

 Hey gang,
 
 Does anyone know where the last release of PECL was that had the tomcat
 files in it for getting PHP to run with Tomcat?  Looks like the version of
 PHP I have (5.2.11) doesn't include the PECL libraries and from what I have
 read, the PECL are currently not released.  I seem to be coming up a bit
 short with the pecl.php.net as well since it doesn't include the dll pack
 for what I am looking for.
 
 TIA,
 
 Josh

Only way to get PHP running in Tomcat is through CGI.  There are serious 
security implications in this setup.  What you should do is setup PHP with 
Apache httpd and use a connector to communicate with Tomcat.  Perhaps you need 
to rethink why would you want to run PHP with Tomcat...

Hi Michael,

I don't know if this is relevant to your problem or not and you didn't mention
whether you're x64 or x86 of XP version. I had problem of tomcat startup as 
service before on x64 (xp or Win03).  You need to replace the tomcat*.exe 
w/ the 64bit version.  The included *.exe are 32 bit.
Here's where you can get 64bit for tomcat5:
http://svn.apache.org/viewvc/tomcat/connectors/trunk/procrun/bin/amd64/
and this is for tomcat6:
http://svn.apache.org/viewvc/tomcat/trunk/res/procrun/amd64/

 Subject: Slow servlet response under WinXP Pro
 
 Hello!
 
 I am working on a servlet application.  It is a data entry application 
 that reads data from a Navision database, and writes data to MySQL.  Here 
 is the setup:
 
 WinXP Pro with Service Pack 3 (dev. box) / Windows 2003 Server (prod. box)
 Apache 2.2.11
 Tomcat 6.0.18
 MySQL 5.1.30
 MySQL Connector 5.1.7
 
 Driver for MySQL:  org.gjt.mm.mysql.Driver

Looking at the source for the connector, you might as well use the 
com.mysql.jdbc.Driver
since the org.gjt.mm.mysql.Driver just extends the com.mysql.jdbc.Driver.  I 
remember
reading somewhere that org.gjt.mm.mysql.Driver is for backward compatibility 
for older apps.
It will be phased out eventually.  You're recommended to use 
com.mysql.jdbc.Driver for
new application development.

 Driver for Navision: sun.jdbc.odbc.JdbcOdbcDriver
 
 There is no native JDBC driver for Navision, so I have to use the ODBC 
 version.
 
 I am having a problem with the time it takes to display a screen, when 
 there is database activity going on.  It can take anywhere from 30 seconds 
 to 90 seconds for the screen to appear.  This is not the time it takes 
 Tomcat to start up for the first time, it is long after that point.
 
 I think I may have found the problem, but I do not know how to fix it. All 
 of our systems (including the production server) have Symantec virus 
 software running.  When I turn the virus checking off, the application 
 runs very well, when I turn the virus checking on, I experience the slow 
 screen display.

From what you describe, this problem doesn't seem to be Tomcat related
since I use Win03 w/ Symantec Anti-Virus along with 3rd party firewall software.
Also, the Win03 is configured as a Domain Controller. I don't have this slow 
response you're reporting.  Your performance issue may lie with:

1) Fragmentation of your partition, especially the partition where the DB 
resides2) Size of your database
3) Configuration of MySQL 
4) Query is optimized (?)
5) Sufficient hardware to handle the DB size (?)

Regards,
Tommy

 I googled for conflicts of Tomcat with virus scanning software, and only 
 found reference to the fact that it can cause performance problems.  But, 
 I could not find a solution, other than turning off the virus scanning. 
 Does anyone know of a solution to this problem?  I have been told that 
 turning off the virus scanning on the production box is not an option.  I 
 have also been told that Linux is not an option. 
 
 I have gone through the Symantec software, and can not find a way to 
 exclude Tomcat, etc. from its process.  Where do I go from here?

Iterate LinkedHashMap gives HTTP 500 in a JSP (NPE)

[Tommy Pham]

Hi,

I have a problem iterating a LinkedHashMapInteger, Object lhmObject. 
The lhmObject.size() gives correct size and lhmObject.keySet().toString gives 
the correct values.
However, if I try iterate the object with lhmObject.keySet() with an empty loop:

for (Integer key : lhmObject.keySet() ) { }

or

for (Iterator it = lhmObject.keySet().iterator(); it.hasNext(); ) { }

I get a HTTP 500 - NullPointerException in the JSP page, which has java.util.* 
and appropriate package.Object for import.
Has anyone seen this before?

Hi Pid,

 I don't know about the other examples, but the above looks like an out

 version.
 
 Without knowing what you're really trying to achieve, it's hard to say, 
 but readHeaders() doesn't seem like the right method to call.

Yes, silly me for just copying and pasting without checking first :)  I also 
tried MultipartStream.readHeaders() method found on the web but the coding 
wasn't elegant (perhaps it was based on the older version of FileUpload since 
the guide is a few years old).  After going through the sample guides on 
Apache's FileUpload site and
going through every class in the JavaDoc, I found the solution to my
problem. The streaming API guide on the home site is very nice and easy to 
implement using ServletFileUpload.parseRequest().

  No, Tomcat runs fine on a JRE.  The problem is that you have a 32-bit
JVM
 installed in a 64-bit OS.  (The 32-bit Windows JVM has only the client
DLL, the
 64-bit only the server DLL.)  The Tomcat installer program expects the JVM
 mode to match that of the OS.  Use a 64-bit JVM.

 Thanks. That's correct what you are saying. But this also means that
 whenever you're  asked to download the latest Java from java.com
 (Sun/Oracle) with whatever Java app, e.g. OpenOffice or something, that
 infamous installer that always installs the Yahoo toolbar in your browser
 when you don't untick that checkbox, you always get the 32bit version JVM
 on windows.
 
 I looked for a 64bit version on their download page to no avail.

  Windows 7 64 bit OS, when installing Tomcat, expects for 64This version

 Not many applications are supported by 64 bit JVM.

You can run Tomcat with 32 bit JVM on 64 bit Windows.  Uninstall the current
Tomcat service you have.  Set the JAVA_HOME environment in the System
Variables to the proper location and reboot.  Download Tomcat, the 32 bit
version of Windows zip file, and install the service via the batch file.

   I believe it's because I only have the jre, not the jdk and I'm
   downloading at the moment.
 
  No, Tomcat runs fine on a JRE.  The problem is that you have a 32-bit
JVM
 installed in a 64-bit OS.  (The 32-bit Windows JVM has only the client
DLL, the
 64-bit only the server DLL.)  The Tomcat installer program expects the JVM
 mode to match that of the OS.  Use a 64-bit JVM.

 Thanks,,
 
  I got Tomcat working with 32-bit JVM.(with additional work as
mentioned
 below)
 
  Installed 32-bit JVM, downloaded apache-tomcat-6.0.26-windows-x86.zip
 and extracted to c:\apache\.
 
  I tried running the $CATALINA_HOME\bin\startup.bat. It started the
 console and i was able to access the index page on my localhost
 
  But when i tried to register Tomcat as Service by running
service.bat it
 failed.
 Copying msvcr71.dll from $JRE_HOME\jre6\bin into
 $CATALINA_HOME\bin\ solved my problem. Now i can register Tomcat as a
 Service by clicking on service.bat.
 
  Any idea on why i am in need of this dll here..
 
 warm regards
 karthick

I just install all the current VS (2005 sp1 to 2010) redistributables (both

DLL by Tomcat, I think it's the way the EXE was compiled (dynamically

 It has nothing to do with tomcat. The missing .dll is JVM dependency.
 The copy can be avoided by setting up the system PATH to include the JRE
 bin folder (usually reboot will be required)
 
 It is something Sun refuses to handle and ships the msvcrt71.dll as part
of
 their dist instead to follow the Windows Logo guidelines and install the
 MSVCRT runtime separately.

[OT] Tomcat on Linux

Hi,

I was wondering what flavor(s) of Linux, if applicable, do you use to
develop? And what Linux flavor(s) do you have Tomcat running production on?

Thanks everyone for your input.  I was hoping to get a better understanding of

HTTP 500.0 on IIS7.5 + JK1.2.36 + TC7.0.26

[Tommy Pham]

Hi,

I'm trying to get the connector (JK 1.2.36) to work for IIS7.5
(Windows 7 Enterprise) but keep on running into HTTP 500.0 Error
following the documentation [1]:

Error Summary

HTTP Error 500.0 - Internal Server Error
Calling GetFilterVersion on ISAPI filter
D:\apache-tomcat-7.0.26\bin\connector\isapi_redirect.dll failed

Detailed Error Information

Here are my configurations:

#worker.worker2.host=otherhost
#worker.worker2.port=8009
#worker.worker2.type=ajp13

# uriworkermap.properties
/examples = localworker

D:\apache-tomcat-7.0.26\bin\connector is mapped as an application
virtual directory /jakarta using ASP.NET v4 integrated application
pool (I've tried the 3 other pools - v4 classic, v2 integrated, and v2
classic - and also failed).  The application pool is configured to run
under Network Service account.  The Network Service account has read 
execute permissions on the folder D:\apache-tomcat-7.0.26 recursively
and write permissions on the D:\apache-tomcat-7.0.26\logs folder.

ISAPI-dll handler mapping, with feature permissions of Read, Script 
Execute, has:
1) *.dll for Request path
2) Executable of D:\apache-tomcat-7.0.26\bin\connector\isapi_redirect.dll
3) Request Restrictions
   a) Mapping  Invoke handler only if request is mapped to:
 File or folder
   b) Verbs  All verbs
   c) Access  Execute

ISAPI and CGI Restrictions allows the said
D:\apache-tomcat-7.0.26\bin\connector\isapi_redirect.dll.

ISAPI Filters has an entry for the
D:\apache-tomcat-7.0.26\bin\connector\isapi_redirect.dll.


My Google-fu isn't very helpful ATM.  Am I missing something?  BTW, I
also have URLScan filter loaded.  Would that interfere with JK
connector?


Thanks,
Tommy

 Is there anything written to that log file?

No, the log file isapi.log never got created.  Only logs I see are
Tomcat's:  catalina*.log, commons-daemon*.log, host-manager*.log,
localhost*.log, localhost_access_log*.txt, manager*.log,
tomcat7-stderr*.log.

 If not, I'd suggest fixing security for D:\apache-tomcat-7.0.26 logs
 and bin folders. IIS runs under special account and it might
 not have read/write permissions to that folder.

By default, IIS 7.5's' application pools are configured to run as
ApplicationPoolIdentity.  I've changed it to the NetworkService
account, which has read, list, and execute permissions on Tomcat's
home directory and recursively, in addition to write/modify
permissions on Tomcat's logs directory.

 Also, why Win7? That's workstation, so unless you are experimenting
 make no sense to use that for anything except serving few clients.
 There is a hard limit on number of connections you can use on any
 workstation-kind of windows.

It's a laptop and used as a portable development/testing system.  Yes,
I'm aware of the limitations of Windows workstations (max 10
connections, etc...).

Hi Chuck and Andre,

Silly me... I figured out what was the issue.  I didn't have the index
page defined in Tomcat's web.xml within the D:\wwwroot.  The eventual
content of this folder will be images anyway.  Would I need to code an
interceptor to detect 404 error and path to redirect the visitor to
another URL instead of Tomcat's default 404 error?

restriction/limit of keystorePass in server.xml for TC7

Hi everyone,

I know this maybe more of Java than Tomcat but in case it's coded
somewhere... Anyway, is there a limit to number of characters (30 - 50) and
limit to certain characters, symbols included, for the keystorePass?  I
only thing I can find for keystorePass limit tomcat 7 are how to setup
SSL and enable TLSes only.  I know some of you are thinking why 30+ when
the password is in plain text file...

TC 9.0.21: ContextListener + Servlet app

[Tommy Pham]

Hello everyone,

I'm trying to write a lightweight and hopefully simple ContextListener +
Servlet application but running into 2 issues I'm unable to find resolution
for and hoping someone would please point me in the right direction:

1)  I'd like to have Tomcat's default servlet serve HTML files only within
directory /path/ and its' subdirectories.  However, I can only get it to
work with this URL mapping "/path/*".  My understanding is that the default
servlet will serve any files within /path/.  Can this be done with URL path
mapping or do I need to write a custom filter?  My servlet's mapping is
"/".  Tomcat's default servlet mapping has "/css/*", "/js/*", "/img/*", and
"/path/*".

2)  I Have this small and simple HTML form:

  
  

My servlet's doPost is triggered but when I iterate the
request.getParameterMap(), it's empty.  When I tried to
request.getParameter("text"), it returned 'null'.  I do have a filter in
place but it's only to log all request access to a database backend
eventually.  That filter is currently dumping it to log.  I've tried
disabling the filter but have the same result.

Thank you,
Tommy

Re: TC 9.0.21: ContextListener + Servlet app

[Tommy Pham]

Hi Mark,

Thanks for the prompt reply.  I'll try with Filter for (1).  I figured out
what I did wrong with (2).  I was missing the HTML attribute 'name' for the
text input.  It's been a couple years since I've wrote a HTML page.

Thanks again for your help,
Tommy

Tomcat embedded

[Tommy Pham]

Hello everyone,

1) Is there an official documentation for embedding TC process?  My search
shows various how-to on other sites.
   a)  If not, I guess I could request to be added to the wiki to
contribute one.  Since I don't quite know all the details of TC, is there a
review process to ensure clarity and complete coverage of embedding process?

2) (probably better to ask the dev list?) I noticed there are some
differences in the official binary distribution vs development environment:
   a)  Official has annotations-api.jar while development has according to
gradle:

default - Configuration for default artifacts.
+--- org.apache.tomcat.embed:tomcat-embed-core:9.0.+ -> 9.0.21
|\--- org.apache.tomcat:tomcat-annotations-api:9.0.21

while the jar file names are different, the classes' name and the jar's
manifest within appear to the same.  I think this is trivial.
   b)  ecj version differences:  the official binary uses ecj-4.10.jar
while the development, per gradle, uses ecj-3.16:

default - Configuration for default artifacts.
+--- org.apache.tomcat.embed:tomcat-embed-jasper:9.0.+ -> 9.0.21
|+--- org.apache.tomcat.embed:tomcat-embed-core:9.0.21 (*)
|+--- org.apache.tomcat.embed:tomcat-embed-el:9.0.21
|\--- org.eclipse.jdt:ecj:3.16.0

Is there a particular reason while such big difference of the major version
4.x vs 3.x?  According to the tomcat-embed maven repository [1]:


org.eclipse.jdt
ecj
3.16.0


Thanks,
Tommy

I have started browsing through the API and have concluded shortly
thereafter that, to me, the best way to implement it is similar to my
current use of ServletContainerInitializer.  Just need another class with
some adjustments and the app could run with Tomcat embedded.  I was hoping
to read something more akin to the official guide:

http://tomcat.apache.org/tomcat-9.0-doc/index.html

Based on my understanding, the getPathTranslated allows the TC's default
servlet to find the file located on the file system to fulfill the
request.  Since it's incorrect, how can I get the TC's default servlet to
work correctly?  Please clarify if I misunderstood getPathTranslated's
purpose or how TC's default servlet would find the file in question to
fulfill the request.

 Thank you,
Tommy

I just tried as you've suggested (only thing that I have is custom is a
passive Filter inspecting what's be passed around to various components
before reaching the TC's default servlet):

Class: org.apache.catalina.connector.RequestFacade
ServletContext Class: org.apache.catalina.core.ApplicationContextFacade
ContextPath: /erm-0.0.1-SNAPSHOT
DispatcherType: REQUEST
HttpServletMapping:
   Class: org.apache.catalina.core.ApplicationMapping$MappingImpl
   MappingMatch: DEFAULT
   MatchValue:
   Pattern: /
   ServletName: default
Method: GET
PathInfo: null
PathTranslated: null
Correction of PathTranslated:
D:\apache-tomcat-9.0.21\webapps\erm-0.0.1-SNAPSHOT\css\jquery-ui\base\index.html
RequestURI: /erm-0.0.1-SNAPSHOT/css/jquery-ui/base/index.html
RequestURL:
http://localhost:8080/erm-0.0.1-SNAPSHOT/css/jquery-ui/base/index.html
ServletPath: /css/jquery-ui/base/index.html
ServletContext.ServletContextName: erm
response: org.apache.catalina.connector.ResponseFacade

As you can see, even with that, I'm still getting a blank page on the
browser.  Also, _if_ I'm to serve static content only, I would better off
using Apache's httpd for more flexible configurations without writing one
line of code :)

Re: TC 9.0.21: ContextListener + Servlet app

[Tommy Pham]

After some further research, it appears the issue I'm encountering is known
since 2007 by IBM at least:

https://www-01.ibm.com/support/docview.wss?uid=swg21259282

While reviewing the JSR-369 history, at jcp.org, it seems that this is
since servlet spec 2.3, perhaps even earlier.  Does anyone know if the
email spec-sub...@jcp.org is the correct email which I can submit a
proposal for updating the JSR-369?  I think the section 3.6 of the servlet
spect should be changed from:

"The getPathTranslated method computes the real path of the pathInfo of the
request."

to:

The getPathTranslated method computes the real path of the servletPath and
pathInfo of the request.  If the pathInfo is not valid, then compute the real
path of the servletPath.

Since the requestURI is comprise of /contextPath/servletPath/pathInfo.  I
think the above would be more accurate to translate the requested path to a
static file on the file system as I've seen by various cases, and possibly
IBM's too.

Servlet name: default , registered class:
org.apache.catalina.servlets.DefaultServlet.

Thank you for the clarification and the heads up. I greatly appreciate it.
I've been thinking about different methods of approach and I think this is
better than servletPath + pathInfo:

return getServletContext() == null ? null : getServletContext().
getRealPath(getRequestURI().substring(getContextPath().length()));

due to less conditional checks yielding better execution time and since I
can't see any condition that either requestURI or contextPath could be null:

hsr = (HttpServletRequest) request;

String pt = null;
final long startTime1 = System.currentTimeMillis();
pt = getPathTranslatedR1();
final long endTime1 = System.currentTimeMillis();
logger.debug(String.format("Correction of PathTranslated R1: %s
ms %s", (endTime1 - startTime1), pt));
pt = null;
final long startTime2 = System.currentTimeMillis();
pt = getPathTranslatedR2();
final long endTime2 = System.currentTimeMillis();
logger.debug(String.format("Correction of PathTranslated R2: %s
ms %s", (endTime2 - startTime2), pt));

 private String getPathTranslatedR1() {
if (hsr.getServletContext() != null) {
if (hsr.getServletPath() != null) {
if (hsr.getPathInfo() != null) {

return
hsr.getServletContext().getRealPath(hsr.getServletPath()
+ hsr.getPathInfo());
}
return hsr.getServletContext().
getRealPath(hsr.getServletPath());
}
return null;
}
return null;
}

private String getPathTranslatedR2() {

return hsr.getServletContext() == null ? null : hsr.
getServletContext().
getRealPath(hsr.getRequestURI().substring(hsr.getContextPath().length()));
}

Correction of PathTranslated R1: 1 ms
D:\apache-tomcat-9.0.21\webapps\erm-0.0.1-SNAPSHOT\css\jquery-ui\base\index.html
Correction of PathTranslated R2: 0 ms
D:\apache-tomcat-9.0.21\webapps\erm-0.0.1-SNAPSHOT\css\jquery-ui\base\index.html


As for the new method of getRealPath(), how does the web container knows
which is the correct one?  Does it then check if the file actually exists
for both getRealPath() and getPathTranslated() and compare?  Going forward
to have progress of my project, I'll have write to my own servlet to handle
static content instead of forwarding to TC's default servlet.  On the
bright side, I think I can have stricter enforcement ie:  "/css/*.css"

Thanks,
Tommy

Re: TC 9.0.21: ContextListener + Servlet app

[Tommy Pham]

Hi Mark,

After some research and thought about internal application flow, I think
the 'cleanest' is have TC's default servlet handle the *.html requests and
use the assigned filter to restrict the access as desired.  Is there a
better approach?  On that plan, I have this mapping for TC's default
servlet and init:

Filter AppFilterAccessLog's servlet mapping:
Servlet name: default , registered class:
org.apache.catalina.servlets.DefaultServlet.
Servlet default's mapping:
 /img/*
 /css/*
 /WEB-INF/*
 /js/*
Servlet default's init parameters:
 listings: false
 debug: 0

If I use *.html instead of /WEB-INF/*, it goes into infinite loop
redirecting / forwarding until exception is thrown (I think that root cause
is servlets' startup ordering).  Below are what my access log filter see
for HttpServletRequest:

Attributes:
javax.servlet.forward.request_uri=/erm-0.0.1-SNAPSHOT/
javax.servlet.forward.context_path=/erm-0.0.1-SNAPSHOT
javax.servlet.forward.servlet_path=
javax.servlet.forward.path_info=/

javax.servlet.forward.mapping=org.apache.catalina.core.ApplicationMapping$MappingImpl@7fc1f887
org.apache.logging.log4j.web.Log4jServletFilter.FILTERED=true
Class: org.apache.catalina.core.ApplicationHttpRequest
DispatcherType: FORWARD [javax.servlet.DispatcherType]
HttpServletMapping:
Class: org.apache.catalina.core.ApplicationMapping$MappingImpl
MappingMatch: PATH
MatchValue: setup/step_0.html
Pattern: /WEB-INF/*
ServletName: default

Below is from the actual filter assigned to TC's default servlet intended
to restrict access:

ContextPath: /erm-0.0.1-SNAPSHOT
DispatcherType: FORWARD
PathInfo: /setup/step_0.html
PathTranslated:
D:\apache-tomcat-9.0.21\webapps\erm-0.0.1-SNAPSHOT\setup\step_0.html
Method: GET
RequestURI: /erm-0.0.1-SNAPSHOT/WEB-INF/setup/step_0.html
RequestURL:
http://localhost:8080/erm-0.0.1-SNAPSHOT/WEB-INF/setup/step_0.html
ServletPath: /WEB-INF
ServletContext.ServletContextName: erm
response: org.apache.catalina.connector.ResponseFacade

I think everything seems correct except the PathTranslated.  It should be:

D:\apache-tomcat-9.0.21\webapps\erm-0.0.1-SNAPSHOT\WEB-INF\setup\step_0.html

where the file is.  I'm unable to find out why it's wrong after a couple
hours of searching since the the browser shows an empty page...  The string
"/WEB-INF/setup/step_0.html" was passed to request.getRequestDispatcher().
According to the doc [1], " If the path begins with a "/" it is interpreted
as relative to the current context root." everything is as it should be
right, other than PathTranslated?  Or did I misunderstood the usage of
getRequestDispatcher().forward()?  Currently, I have 4 filters in place and
all are in passive monitoring mode.  None of them have the code logic to
perform their intended functions.  3 filters mapped to URL /* and one
assigned to TC's default servlet.  I'll work out their filtering order
before the intended functions are implemented.

Thanks,
Tommy

I was using "/WEB-INF/*" as a test of the scaffolding for my application
since previously "*.html" ended up infinite loop which, eventually, it
threw an exception.  Now that I've got "*.html" working, I'm still getting
a blank page.  The HTML files are only served as UI for the initial setup
of the application.  There won't be any static files other than JS, CSS,
and images when the application is fully configured by administrator.  Here
are the servlets configuration:

Hi Mark,

Your one suggestion helped me resolve this issue and another (WebSocket) in
less than 10 minutes that I've spent over 8 hours going through 5-6 classes
in addition researching online trying to identify the root cause.  Thank
you very much!

Hi Mark,

I've finally started my embedded Tomcat project.  I'm running into NPE for
the JSP servlet.  From the log:

https://pastebin.com/thiADVYE

I think I have everything setup correctly because accessing
http://localhost/css/sample.css works.  I've even added the 5 listeners in
the server.xml configuration while troubleshooting.  My JSP is really basic:

https://pastebin.com/X7R8weKv

When I inspecting the code where the NPE is thrown:

// Get the cached EL expression factory for this context
expressionFactory =
JspFactory.getDefaultFactory().getJspApplicationContext(
compiler.getCompilationContext().getServletContext()).
getExpressionFactory();

I couldn't figure out which part is the NPE.  I have the following jars:

*) all 4 tomcat-embed-*
*) tomcat-annotations-api
*) ecj-3.21
*) jstl 1.2 ( to troubleshoot this NPE )

I forgot to mention that the directory path org/apache/jsp was created
within workDir  /mnt/d/java/projects/ewa/build/ewa/temp/ROOT
