But what about libmlib_image.so? That's the one it's complaining about.
Here's what I can see on a non-X Linux system:

$ ldd /usr/lib/jvm/java-1.5.0-sun-1.5.0.17/jre/lib/i386/libawt.so
linux-gate.so.1 =  (0xb7f67000)

libc.so.6 = /lib/i686/cmov/libc.so.6 (0xb7d52000)
/lib/ld-linux.so.2 (0xb7f68000)

Still, compiling and running a color example works fine for me. (From
the command line, that is.) It works because of the built-in value for
the system property java.library.path.

Download an example that *I think* requires AWT.

Pantone example : Spot Color

The result looks fine!


I read somewhere that whenever java is installed no a linux box
without x (in my case it's a remote vps) java omits certain graphics
related libraries like AWT (naturally).


There is no X11 server on that machine; the Sun Java is installed via
the package manager; everything seems fine.


I also read that you can run java headless to avoid the dependencies
to X. Now is there a way to run tomcat (or add variables to tomcat's
startup.sh) to avoid having these dependencies?


Aren't the dependencies simply required? I think the JVM wants to load
libmlib_image.so because it is needed.

Try running your Itext examples from the command-line on your server. If
that works, I'd look for the issue in how you set up the environment for
Tomcat.

I don't know if that could be a problem, but is there more than one Java
installation on your machine? Do Java library directories show up in the
output of ldconfig -p? Could that confuse the JVM about what library to
load?

Query on Tomcat Server.xml

2009-08-31 Thread Tk, Pramod (NSN - IN/Bangalore)

Hello All,

 

The below tag is used to for making use of keystore on snmartcard. It
works fine

 

Connector port=443 protocol=HTTP/1.1 SSLEnabled=true

 maxThreads=150 scheme=https secure=true

 clientAuth=false sslProtocol=TLS protocols=TLSv1 

 algorithm=SunX509 

 keystore=NONE keystoreType=PKCS11 keystoreProvider=smartcard
provider keystorePass=X  

/

But ,

 

What I want to make is to remove keystorePass=X tag and give
this keystore password when tomcat starts up. 

 

I presume this type of hardcoding in server.xml is security loop hole.  

 

Apache asks keystore password during its start up.

 

Any suggestions to avoid the hard coding  of the password in tomcat will
appreciated.

 

 

Thanks :-),

Pramod TK

Not yet, but I'll start this evening hopefully.

Yes, this should work. It is the contract for ACTION_COMMIT that it sends
the headers down the wire regardless of which Connector you are using.
I implemented this and it's working - great!

My wrapping hook defines just an abstract method beforeCommit. This
hook is set on the coyote response (if a session was requested, just as
an optimization), and restores the original action hook at the end of
beforeCommit.

The hook can be seen here: http://is.gd/2JcSh
The usage of the hook from within the valve is here: http://is.gd/2JcVD

Doing this kind of thing is always a risky proposition, since there are
lots of cases to test.
Hmm, which cases do you have in mind?

The main one I'd worry about is that it isn't guaranteed that ACTION_COMMIT
won't be invoked more than once on a request (although it is rare), so you
need to be able to handle this case. The second time it is called, the
o.a.coyote.Response object will show itself as committed, so that is all you
need to check. I'd keep a reference to the Response in my ActionHookWrapper
to keep my sanity, but it should also be the 'param' value to the action
method (but I haven't check if this is true in all Connectors).
Yes, that's exactly what I did, and I also checked for the isCommitted
property and additionally restored the original hook after the
intercepting hook was invoked.

The other one would be that Tomcat reuses instances of it's low-level
internal objects. So the Valve that wraps the ActionHook needs to check
that it isn't re-wrapping an instance of your ActionHookWrapper.
Uuh, good to know, this might lead to weird issues. I'll add a check for
this.

Thx cheers,
Martin

Any other thoughts on this?

Two related thoughts:

1. Do you need all of the content to be generated before this header is
set? If so, you'll need another strategy for 100% response buffering
in order to meet your needs (say, calculating a cryptographic hash of
the response content to include in a header).

2. If you don't need #1, then why do you want to delay the header
setting as long as possible?
To answer this, I need some more words. Basically, I'd like to add the
cookie only under certain conditions, but then after all session
modifications are definitely done. So what am I trying to do in more
detail?

I'm creating the memcached-session-manager ([1]) as a session-failover
solution when running on tomcat. The memcached-session-manager is
basically storing a session additionally in a memcached node after the
request was processed - as a backup of the session. Normally, the
session is read from the jvm local session map. But if a request shall
be served for an unknown session id, the session is looked up in the
memcached and restored if found. Sessions are still kept locally to have
only one roundtrip to memcached for each request. As there might be
several memcached nodes used for session backup, the memcached node is
encoded in the session id, so that the appropriate memcached node is
selected for backup or restore.
In the case of a memcached failover, the memcached-session-manager
selects another memcached node for session backup, and changes the
session id accordingly. To let the client know that the session id has
changed, it must send a new JSESSIONID cookie with the new session id.

So for this case, I want to defer the memcached-failure detection as
long as possible, until the response is committed. If I have a memcached
node in failure state, the response will also get a cookie with the new
session id, and at the end of the request the session id will be
migrated to the new memcached node.

Cheers,
Martin

 I presume this type of hardcoding in server.xml is security loop hole.

Not really.

If you don't put the password in server.xml, where are you going to put it?  
The server.xml file can have the same access constraints applied to it as any 
other location for the password.

Re: java.lang.UnsatisfiedLinkError: running tomcat on java headless?

2009-08-31 Thread Tim Funk

1) Are you passing -Djava.awt.headless=true to tomcat via CATALINA_OPTS 
 (or JAVA_OPTS)
2) I have found that even if you are headless, you can't use all the 
Graphics/awt stuff. I wish I could recall what it was, but I thought the 
death was in  similar manner. (But this was also a few years ago). Of 
course -  since you are using iText - this shouldn't be an issue.

You're probably alluding to:

  You either need to run headless or run an alternate X-server. [...] if

  java.awt.headless=true

Indeed, isHeadless() returns true for my Java 5 and 6 installations.

public class Headless {

 Doing this kind of thing is always a risky proposition, since there are

 Hmm, which cases do you have in mind?

Well, you have to test it when you have a tiny response (including
things like redirects, 304s, etc.), when you have a huge response (large
static file, perhaps), when you have a large response AND a redirect
(which might actually fail on its own), etc.

 2. If you don't need #1, then why do you want to delay the header
setting as long as possible?

 To answer this, I need some more words. Basically, I'd like to add the
 cookie only under certain conditions, but then after all session
 modifications are definitely done.

I would recommend that you re-think your architecture if this is a
concern. It's best to do all your state-changes on the server /before/
any response is generated. If you stick to this rule, then you can set
your cookie before the 1st byte of the response is even emitted, and it
will significantly uncomplicate your life.

 So what am I trying to do in more detail?
 
 I'm creating the memcached-session-manager ([1]) as a session-failover
 solution when running on tomcat. The memcached-session-manager is
 basically storing a session additionally in a memcached node after the
 request was processed - as a backup of the session. Normally, the
 session is read from the jvm local session map. But if a request shall
 be served for an unknown session id, the session is looked up in the
 memcached and restored if found. Sessions are still kept locally to have
 only one roundtrip to memcached for each request. As there might be
 several memcached nodes used for session backup, the memcached node is
 encoded in the session id, so that the appropriate memcached node is
 selected for backup or restore.
 In the case of a memcached failover, the memcached-session-manager
 selects another memcached node for session backup, and changes the
 session id accordingly. To let the client know that the session id has
 changed, it must send a new JSESSIONID cookie with the new session id.
 
 So for this case, I want to defer the memcached-failure detection as
 long as possible, until the response is committed. If I have a memcached
 node in failure state, the response will also get a cookie with the new
 session id, and at the end of the request the session id will be
 migrated to the new memcached node.

Shouldn't you know when you first try to access the session that a
memcached-failure condition has been detected? If so, you don't have to
wait until the end of the response to put that into a header (and why do
you even need it in the header)?

This doesn't sound like you need any delayed processing whatsoever.

Other than Chuck's suggestion to use the Tuckey's venerable url-rewrite,
you could also deploy your webapps differently, like this:

Host name=www.domain1.com appBase=./domain1 /
Host name=www.domain2.com appBase=./domain2 /

I think you'll have to write your own code that reads the keystore
password from the console (and displays it, since I don't think Java can
control a pty device very well) and then sets up Tomcat. If you're
trying to be cute, you could pop-up a tiny GUI window to get the
password, but that will significantly increase the amount of memory
required just to get Tomcat started because the GUI subsystem must be
started.

Or, you could hack Tomcat's existing bootstrap classes to do the same
thing, but it might end up being more complicated than you think
(because IIRC Tomcat uses commons-digester to configure everything).

In either case, you'll have to figure out how to get Tomcat into the
background after accepting the password, too, unless you just expect
users to press CTLR-Z and then type bg or whatever.

You might want to consider developing on the same platform you are
targeting for production. Yes, Java is supposed to run everywhere but
there are certain environmental factors that can ruin your day (like X
libraries). Note that Microsoft Windows always has X-ish capabilities
available because the console runs a windowing system.

Running Java headless doesn't mean X is not required: it just means
that X doesn't have to be /running/. Some X libraries may still be
required to use certain functions. You used to have to run xvfb if you
wanted any kind of AWT interaction. Now, that restriction has been lifed
(by going headless) but I think the libraries still need to be available.

Have you tried asking the iText folks? They are much more likely to know
the answer to this. Tomcat, as you might guess, has no requirements for
X whatsoever.

You shouldn't have to specify the 'factory'. Is there a reason you do?

You also shouldn't need testOnReturn and testWhileIdle, though I

Do you get a similar message? If so, please post it. Unfortunately, it
doesn't look like it dumps its test configuration.

I can't imagine that it matters, but you might want to take out the
spaces after the = signs in your XML (like validationQuery =true).

You could also try writing some code like this:

org.apache.tomcat.dbcp.dbcp.DataSource ds = ctx.lookup(jcbd/oracle);
System.out.println(validationQuery= + ds.getValidationQuery());
System.out.println(testOnBorrow= + ds.getTestOnBorrow());
System.out.println(testOnReturn= + ds.getTestOnReturn());
System.out.println(testWhileIdle= + ds.getTestWhileIdle());

...and see what it emits. I suspect something is wrong with your
validation query being set on the data source.

maling list archives and bug tracker dumps for academic research evaluation

2009-08-31 Thread Iqbal, Aftab


Hi,

I am a PhD student at DERI (http://www.deri.ie), Galway, Ireland. We are 
working here on a research to address some issues in
software development processes and how can make software development and 
specially its management efficient[1]. For the
evaluation of our research, we are looking for data from mailing list archives, 
bug trackers, source code, subversion logs of an open source, live long project 
such as Apache Tomcat.

Although, we have Web access to the subversion repository of Apache Tomcat but 
we require dumps of the bug tracker of Apache Tomcat development and mailing 
list archives to do our evaluation.

Your help will be highly appreciated and we will be very happy to share the 
results of our evaluation with you.

If this mailing list is not intended for this email then please guide me to 
whom i can contact for it.

thanks and looking forward for your kind response.

Bill, Thanks for your prompt response.
I see that it will be available in Tomcat 6.0.21 onwards. Do you know when will 
it be available for download ?

Also, does it resolve the 8k size limit on AJP connector or if there is a way

 I've a setup where Apache 2.2 is fronting Tomcat 6.0.20. They are talking 
 AJP/1.3
 Using mod_proxy_ajp.
 I've a URL protected by client SSL. Apache prompts for client certificate 
 and I can get to the cert in my webapp (servlet).
 However, when the cert have intermediate CAs, I still only get the leaf 
 cert and Not the cert-chain in my tomcat webapp !

 Could not find a setting on apache (mod_proxy_ajp) to send cert-chain.
 And even if it did, the tomcat code looks like it only wants to get single 
 cert!
 org.apache.jk.core.MsgContext public void action(ActionCode actionCode, 
 Object param) {...

} else if( actionCode==ActionCode.ACTION_REQ_SSL_ATTRIBUTE ) {
Request req=(Request)param;

// Extract SSL certificate information (if requested)
MessageBytes certString = 
 (MessageBytes)req.getNote(WorkerEnv.SSL_CERT_NOTE);
if( certString != null  !certString.isNull() ) {
ByteChunk certData = certString.getByteChunk();
ByteArrayInputStream bais =
new ByteArrayInputStream(certData.getBytes(),
 certData.getStart(),
 certData.getLength());

// Fill the first element.
X509Certificate jsseCerts[] = null;
try {
CertificateFactory cf =
CertificateFactory.getInstance(X.509);
X509Certificate cert = (X509Certificate)
cf.generateCertificate(bais);
jsseCerts =  new X509Certificate[1];
jsseCerts[0] = cert;
} catch(java.security.cert.CertificateException e) {
log.error(Certificate convertion failed , e );
return;
}

 Can possibly change it to something like (assuming the cert-chain gets 
 passed in   WorkerEnv.SSL_CERT_NOTE)
Collection ? extends Certificate certCollection = 
 cf.generateCertificates(bais);
X509Certificate [] certs = new 
 X509Certificate[certCollection.size()];
int i = 0;
for (Certificate cert: certCollection) {
certs[i] = (X509Certificate)cert;
i++;
}


 I tried it w/ Tomcat 5.5.27 as well with similar result.
 Also, tried with original Java connector 
 org.apache.jk.server.JkCoyoteHandle  the new 
 org.apache.coyote.ajp.AjpProtocol with similar results.

 Seems like a bug ?? Or am I missing anything ?


Yes, it's a bug. Specifically 
https://issues.apache.org/bugzilla/show_bug.cgi?id=39637.  With mod_jk, the
JkOptions +ForwardSSLCertChain directive works.  I'm too lazy to see 
if it has been implemented in mod_proxy_ajp.


 Any prompt help is appreciated.

IO package and the third test from the CGlib framework that we used from
Hibernate. In all instances, there is a call to a method/constructor on the
String object in the stack.

I'm about to try Java 6 to see if it makes a difference.

  I have a Spring/Hibernate app running in Tomcat 5.5.20 that we've tested
 in
  many environments that is currently faltering when running in a Ubuntu 7
  VM.
  Basically on startup, frequently, the startup process will halt when
 trying
  to read Hibernate's HBM files and in various other places in startup
  process. When it stops both CPUs are pegged at 200% usage by the java
  process (from 'top'). At this point, the only recourse is to kill the app
  with kill -9 pid. Occasionally the app will start all the way up.
 Then,
  I can trigger a re-index of the content in the app's database using
 Lucene
  and the app will freeze again.
 
  The only thing I've been able to find in common about these operations is
  that they seem to be heavy I/O.


 One trick would be to take a thread dump when the app locks up.  kill -3
 pid will trigger such a dump.  The output will be in one of Tomcat's
 logfiles (catalina.out by default, I think).  That might allow you to get
 debugging information, as you're getting the data without having to enable
 JPDA.

 Sometimes it's useful to take several thread dumps, a few seconds apart,
 and
 analyse them.  However, given your suspicions of a race condition, I'm not
 sure that's appropriate

 Hi,
 
 I am a PhD student at DERI (http://www.deri.ie), Galway, Ireland. We are

 evaluation of our research, we are looking for data from mailing list 
 archives, bug trackers, source code, subversion logs of an open source, live 
 long project such as Apache Tomcat.
 
 Although, we have Web access to the subversion repository of Apache Tomcat 
 but we require dumps of the bug tracker of Apache Tomcat development and 
 mailing list archives to do our evaluation.
 
 Your help will be highly appreciated and we will be very happy to share the 
 results of our evaluation with you.
 
 If this mailing list is not intended for this email then please guide me to 
 whom i can contact for it.

The Apache Infrastructure Team usually handles requests like this but
since I am also a member of that team as well as a Tomcat committer I
should be able to get this for you.

Could you provide a time frame for the data you are interested in? To
give you an idea of the volumes involved, in compressed form the
complete dev archive is 121MB, the users archive 233MB and the announce
archive 15KB.

For the bugs it will be easier to give you a complete dump of the
Bugzilla database. That was about 300MB (compressed) the last time I
took a copy.

The easiest thing for me to do is to put this somewhere under
http://people.apache.org/~markt and let you download it.

Not compiling JSP's

2009-08-31 Thread Carl

My environment (fresh install) (this is a backup server that can be used for 
testing and to allow us to upgrade the current production server running Tomcat 
5.5):

Slackware 12
Java 1.6.0_13 (Actually installed in May)
Tomcat 6.0.18

My development system:

Windows XP
Java 1.6.0_07
Tomcat 6.0.16
NetBeans 6.5

The problem:

Tomcat will compile the first few JSP's.  Then, it stops compiling them. 
Nothing in the logs says there is a problem compiling the JSP.  They are the 
same JSP's run in the development environment.  If I copy the .java and .class 
files from the work directory on the development computer, that JSP will run 
just fine.  The Jasper flags in web.xml (in the tomcat/conf directory) are all 
default except I added modificationTestInterval = 0 (didn't seem to have any 
effect.)

The war was built using NetBeans 5.5 and Java 1.5.0_07 (I have been doing this 
so I didn't have to deal with the compatibility issues on the production 
server.)

I am baffled and ready to accept help from any and all sources.

Hmm. That smells like a JVM issue to me, particularly if it goes away
when you use JPDA.

Things to try:
- use a 1.6 JVM
- try different JVM settings, particularly GC related ones
- switch to/from client from/to server JVM

  Hmm, which cases do you have in mind?
 
 Well, you have to test it when you have a tiny response (including
 things like redirects, 304s, etc.), when you have a huge response (large
 static file, perhaps), when you have a large response AND a redirect
 (which might actually fail on its own), etc.
Yes, these are good things to check, I'll write tests for such cases.

 
  2. If you don't need #1, then why do you want to delay the header
 setting as long as possible?
 
  To answer this, I need some more words. Basically, I'd like to add the
  cookie only under certain conditions, but then after all session
  modifications are definitely done.
 
 I would recommend that you re-think your architecture if this is a
 concern. It's best to do all your state-changes on the server /before/
 any response is generated. If you stick to this rule, then you can set
 your cookie before the 1st byte of the response is even emitted, and it
 will significantly uncomplicate your life.
As I'm creating a library that shall be usable in different projects,
it's not on me to decide when the session is accessed and when the
response is created.

However, if there will be issues with the current approach (intercepting
the response.commit) I'll have to reconsider a different way.

 
  So what am I trying to do in more detail?
  
  I'm creating the memcached-session-manager ([1]) as a session-failover
  solution when running on tomcat. The memcached-session-manager is
  basically storing a session additionally in a memcached node after the
  request was processed - as a backup of the session. Normally, the
  session is read from the jvm local session map. But if a request shall
  be served for an unknown session id, the session is looked up in the
  memcached and restored if found. Sessions are still kept locally to have
  only one roundtrip to memcached for each request. As there might be
  several memcached nodes used for session backup, the memcached node is
  encoded in the session id, so that the appropriate memcached node is
  selected for backup or restore.
  In the case of a memcached failover, the memcached-session-manager
  selects another memcached node for session backup, and changes the
  session id accordingly. To let the client know that the session id has
  changed, it must send a new JSESSIONID cookie with the new session id.
  
  So for this case, I want to defer the memcached-failure detection as
  long as possible, until the response is committed. If I have a memcached
  node in failure state, the response will also get a cookie with the new
  session id, and at the end of the request the session id will be
  migrated to the new memcached node.
 
 Shouldn't you know when you first try to access the session that a
 memcached-failure condition has been detected?
Nope, the memcached might fail directly in the *moment* after the
session was created but before the session is going to be stored for
backup - of course this is not very probable, but possible. And for long
running requests the probability increases.

  If so, you don't have to
 wait until the end of the response to put that into a header (and why do
 you even need it in the header)?

Just copying what I already wrote:

  In the case of a memcached failover, the memcached-session-manager
  selects another memcached node for session backup, and changes the
  session id accordingly. To let the client know that the session id has
  changed, it must send a new JSESSIONID cookie with the new session id.

Cheers,
Martin


 
 This doesn't sound like you need any delayed processing whatsoever.

Agree.

The other interesting point is that all of those are hung in places where
they would naturally be allocating an object or have very recently allocated
an object, and the JVM *might* in theory be growing the heap.  Bradley, are
your initial and maximum heap sizes identical (I suspect not from your

 Martin,
 
 Thanks for your quick reply.  I am presently downloading the latest JDK (to 
 the box that is building the war) to see if that makes a difference.
 
 There are no error messages in any of the logs, including the 
 localhost*.log.
 
 Thanks,

Have tried with -server flag. Same problems.

I agree with you on JVM problem especially given that all the blocked
threads are blocked in calls to the String object. Problem is I'm not doing
anything exotic with the JVM. We simply did an apt-get to get the latest
Sun JVM for Ubuntu. I've been searching their forums as well for any mention
of incompatibilities with Sun's JVM.

Strange problem with data source Tomcat 6.0.18

Hi everyone,

I sincerely hope someone can point me in the right direction here. I have
set-up a data source using the context.xml file located inside my META-INF
and added the relevant entry in the web apps web.xml. I also have the MySQL
connector/j driver inside my own apps lib as well as inside the server's
lib(same version). When running the app on my local machine it works without
any hassles b.t.w. I am connecting to the remote db server from my local
machine.

Now when I deploy the .war to the server in which the db is running, the
archive is deployed but when I now try to get a connection to the same db
and same server as from my local machine I get:

Cannot create JDBC driver of class '' for connect URL 'null'

I do test whether I can get a context before trying to connect to the db:

try {
Context initialContext = new InitialContext();
Context envContext = (Context)initialContext.lookup(java:comp/env);
if(envContext != null) {
DataSource dataSource =
(DataSource)envContext.lookup(jdbc/wuMaps);
conn = dataSource.getConnection();
} else {
log.error(Houston we have a problem No Context!);
}

The name jdbc/wuMaps is also exactly the same in the web.xml as well as the
context.xml, any ideas why the app cannot find the data source on the
server? I look forward to hearing from everyone.

 Subject: Re: slight problem with Tomcat and Httpd working together.

 Something that I am not understanding.  If the context.xml files are
 truly ignored how can each of the companies be able to login?

You appear to have answered your own question, since you don't really have the 
Context elements in server.xml.

 You're saying if I create the conf/Catalina/[host]/[appName].xml
 I can add them on the fly?

You can always add webapps on the fly, if you have autoDeploy set.

 would it be something like conf/Catalina/localhost/xyzcompany.xml?
 Isn't this for JAAS type realm?

The location of the Context element has nothing to do with whatever Realm 
is being used.

 I know best practice is keeping the webapps directory inside of
 $CATALINA_HOME.

That's not best practice, just the default one.

 What would I have to change in my configuration to be able to 
 serve new projects under the new displaced webapps folder

Just the appBase attribute of the Host element; point it to the location of 
your webapps.

That's wrong. The driver must not be in both locations. It must be made
available to the common classloader, which provides classes to both the
server and the applications.

Discard the driver from your application.

Are you doing a proper deploy using the manager application? Or removing
the WAR and properly waiting for Tomcat to discover this?

Or are you improperly clobbering the WAR? That would leave a stale
context.xml for your application in place.

Hey Chuck,

Re: 100% usage and hanging on startup of Spring/Hibernate app in Tomcat 5.5 on Ubuntu 7


 I agree with Mark: the three threads you showed were different

(different ids), and showing different call stacks. Are you saying that

each thread dump you took represents multiple thread dumps where that

particular thread didn't progress /at all/ over your multi-dump sample?


The three thread dumps were from three different occurrences of the same
problem and three consecutive startup attempts.

With each occurrence, the startup process hangs in the middle of
initialization. I took 2-3 jstack dumps that were identical each time. After
that, I killed the process (kill -9 pid) and started it again.

So, while it's not hanging in the same place every time, it's definitely
hanging every time. And because it's the main initialization thread that is
hanging, once it hangs, it never gets any further.

Sorry for the confusion and thanks for the help!

 The other interesting point is that all of those are hung in places where

they would naturally be allocating an object or have very recently allocated

an object, and the JVM *might* in theory be growing the heap.  Bradley, are

your initial and maximum heap sizes identical (I suspect not from your

original message)?  If not, what happens if you make them so?


From my original post, I'm setting the following memory parameters:

-Xmx512M -XX:MaxPermSize=128m

so I'm not setting an initial heap size at all. If I remember correctly,
Tomcat's initial heap size default's to 64MB or something.

I'll try to set the initial and max to the same to see if that has any
effect.

2009-08-31 Thread Leon Rosenberg

Hello,
This indeed sounds like you have problems with one of the spaces,
please add following option to the JAVA_OPTS (or whatever you are
using) to seubmit jvm parameters:
-XX:+PrintGCDetails

And, no tomcat's initial heap size don't default to 64Mb. The JVM
allocateds a heap dependent on your computer type, for example the 1.5
VM would identify a 2 core 2 GB machine as 'server' and allocated more
memory than with 1 core cpu.

http://72.5.124.55/docs/hotspot/gc5.0/ergo5.html

regards
Leon

P.S. I know the link looks strange it come ups from google:
http://www.google.de/search?q=hotspot+memory+ergonomicsie=utf-8oe=utf-8aq=trls=org.mozilla:en-US:officialclient=firefox-a

P.P.S I had a similar situation once, as a client had set space sizes
manually (new and old) and the old space was full. The VM was only
full garbage collecting which led to 100% CPU usage and strange thread
dumps. The above option would help you in this case to identify the
full gc runs previously and during the hangup.

 https://issues.apache.org/bugzilla/show_bug.cgi?id=47769

That's a very good start. Thanks!

There is however still one vital piece of information missing in the
proposed documentation update. It now clearly states that resource-ref
in the web.xml deployment descriptor is optional, but it still doesn't
explain what exactly it is that using resource-ref buys me.

Okay, it's optional, so I don't HAVE to use, but if I DO use it, what
possible advantage does it have?

Don't get me wrong, I'm not trying to be clever, just honestly
wondering about this. But consider the following analogy. Putting a
file called 'nobody-reads-this.txt' in your root directory is
obviously optional too. I mean, you -can- put this file there, but if
you do that nothing happens. It's a filename I just made up and of
course Tomcat doesn't know about it. To me, using resource-ref feels
exactly like this. You -can- put this in your web.xml, but as far as I
can see nothing changes.

Now, maybe, just maybe, it has something to do with compatibility with
other servlet containers? I have tried war archives with Jboss, and at
least on Jboss resource-ref isn't needed either. DataSources appear in
the java: JNDI space, just as in Tomcat. Only the exact location is
different, but resource-ref does not seem capable of doing any name
aliasing and thus can't be used for that purpose either.

 Hi there Michael,
 
 Ok, I removed the mysql jar from my app and left it in tomcat/lib
 
 I also undeployed and then redeployed the war file via the manager app
 but the problem persists.

Then I suspect a typo in your resource definition. I once had
Resource/@url instead of Resource/@uri with the MySQL driver.
The error was just:

  Cannot create JDBC driver of class 'com.mysql.jdbc.Driver'
  for connect URL 'null'

Double-check your resource definition.

Re: Not compiling JSP's

2009-08-31 Thread Carl


Martin,

On the theory that the problem was the JDK, I clean/built the war using my 
development computer (Java 1.6.0_11) and deployed it to the test server 
(Java 1.6.0_13).  I test compiled all the JSP's on the development computer 
just to be certain there wasn't some failure there.  When the war is 
deployed to the test server, there are essentially no files in the Tomcat 
work directory (as expected).  The system runs perfectly on the development 
computer but shows the same problems on the test server (creates a few .java 
files, compiles them properly and then stops compiling the JSP's.)


This is the startup of Tomcat from the catalina log:

Aug 31, 2009 5:25:57 PM org.apache.catalina.core.AprLifecycleListener init

This looks very normal to me.

There are no errors in the catalina.out or the localhost log.

I have set modificationTestInterval to 0.

Odd that some JSP's get compiled and some won't.  Note that it is always the 
same JSP's that will not compile.


Have installed Tomcat several times and never had problems.

Any help is appreciated.

TIA,

Carl

Hi there Michael,

Thanks so much for all of your assistance. I am going to try all of these
suggestions and let you know what the results are. One thing though, with
what you just mentioned I technically do not have to include the Context
definition bit at all in the context.xml and can basically just use the
Resource definitions on its own and Tomcat will figure out all of the rest.

Hi Michael,

A combination of factors did it and this is definitely one of those moments
where you want to kick your own *ss ;)Basically what I did was make all
references everywhere, and I mean everywhere, to wuMaps to wumaps. So this
is in the resource reference in the web.xml in the Java class, the path as
well as docbase and walla! Thanks again!

 Try capitalizing context to Context.

Also make sure there is no conf/Catalina/[host]/myapp.xml file lying around; if 
so, it will override your META-INF/context.xml file.  The copy in 
conf/Catalina/[host] is created during deployment, and removed when the webapp 
is undeployed.  However, if you're simply replacing the webapp, the old 
myapp.xml file may hang around.

Depends on how wide a scope you want for the Resource.  If it's intended to 
be for just one webapp, the Resource element must be nested inside the 
Context element for that webapp.  If you want the Resource to be available 
to all webapps, you can place it inside a GlobalNamingResources element which 
itself must be inside the Server element; in this case, you will need a 
ResourceLink element inside the Context of each webapp that you want to 
give access to said Resource.  Regardless, you do need the Context element.
