Re: Interrogating JRun

[Ben Groeneveld]

Howard,

I think you can get at port info using the regular servlet API, but JRun 
provides for quite a bit of internal info using its JMX interface which 
you can review in the admin manual.  It is very cute with an HTML front 
end. 

Hope that helps, BenG.

response.setHeader("connection: close") with IIS becomes Keep-Alive

[Ben Groeneveld]

In response to an HTTP POST I am performing a

response.setHeader("Connection", "close");

My JRun4 is configured with IIS.  I think this used to work, but perhaps 
something else has changed (did browsers always use Keep-Alive on 
POSTs?).  It is currently not working - for a couple months now, and IIS 
overrides this with a "Connection: Keep-Alive" - which is what the 
browser requests.  Browser (IE and NS) requests are coming into my 
server as POSTs, and their connections are staying open and not 
closing.  This creates a problem for my application in situations where 
IE or NS only want to have two concurrent socket connections open - I am 
using one of those two for a dedicated, persistent connection on a 
custom app. 

If I configure JRun to run using it's webservice and bypass IIS my app 
runs as designed.

I have used the sniffer program provided with JRun to verify that the 
setHeader() call is not working.

Help or pointers would be appreciated to make this call work with the 
JRun connector for IIS. 

Thanks, BenG.

Re: Invalidating a session with Jrun SessionService

[Ben Groeneveld]

Gavin, you might try "registering" each user's session reference in an 
object accessible to the admin so that he/she can peruse and act on them 
using session.invalidate().  Hope that helps, BenG.

Gavin, I am not familiar with that approach.  As an alternative, you may 
try session.invalidate() - I use it frequently.  Hope that helps, BenG.

Well of course that is the beauty of our profession - we are all writing

Re: JRUN Stability- reply 2

[Ben Groeneveld]

Kathy, we run primarily on windows.  I have done some tests on linux, 
but not to this extent.

Our app uses keepalive connections that remain open, so we need a very 
high level of concurrency.  In production we run at 750 concurrent 
connections (users) per node.  The JRun server doesn't seem to 
pre-allocate the threads, so they remain upper limits.  We also run with 
a non-sanctioned patch provided by macromedia folks, because regular 
JRun will get stuck at 1000 activeHandlerThreads.  They gave me the 
patch, but in followup email have been quiet to answer my request for 
info on when the change would be incorporated into the base code.  I was 
working with someone by the name of Stephen Dupre last August; he was 
most helpful.

Using the patch we have tested just beyond 1800 in our lab with the IBM 
jvm and 1700 with the sun jvm, before we run into memory management 
problems.  We use the following jvm args now with sun 1.4:

-Xms128m -Xmx128m -Xss64k

In order to use such high settinmgs you also need to adjust your web 
server because by default they don't permit such high levels of 
concurrency either - I assume as a precaution against DOS attacks.  So 
you have to adjust your Apache or IIS settings.

If I recall my experiments properly, the jvm on windows is limited to 
2048 threads, so to get beyond that on a single machine you need to have 
multiple vm's.  So, I put several JRun servers under IIS, but then I 
started to run up against some upper limits of IIS.  I never got further 
than 4000 concurrent connections for a single win2k box with 1 cpu, and 
that was with three JRun servers under IIS.

Hope that helps, BenG.

Re: Increasing Logfile count

Alex, search for 5 in 
JRun4/servers/default/SERVER-INF/jrun.xml.  You can also change the log 
file size, which I find convenient to do.  Hope that helps, BenG.

Re: JRun mysteriously crashing, strange errors in Apache

[Ben Groeneveld]

Richard, that's pretty much it then, except that you can create a custom 
logger to catch stdout and stderr if you want; refer to the manuals for 
that. 

You can usually tell if JRun shutdown or got torched.  On a graceful 
shutdown, the destroy methods of servlets will be invoked, including the 
builtin JRun servlets, and they log misc things.

If you are running from the console, and JRun looks like it's dead, but 
perhaps overloaded as you describe below, you can examine the threads 
with Ctrl-Break w/o affecting processing to get an idea of where it's stuck.

Hope that helps, BenG.

Re: JRun mysteriously crashing, strange errors in Apache

[Ben Groeneveld]

Rchard, I'm not sure by what you mean to say in that logging is always 
on, and println() for System.out and System.err will go to stdout and 
stderr, so I suspect that if you redirect them you will capture them.  
All other logging should be in JRun4/logs.  Does that make sense?  BenG.

Re: JRun mysteriously crashing, strange errors in Apache

[Ben Groeneveld]

I believe that you might find more logging info if you run from the 
command line and redirect stdout and stderr to a file.  With JRun3 these 
used to be captured in a separate log files, but with JRun4 this is no 
longer the default.  I do believe that the documentation talks about how 
to setup such logging, though.  Hope this helps, BenG.

Re: High Traffic JRun4 Settings

Juan

I agree, that's a good article, and we have used it when we were with 
JRun 3.1.  With JRun3.1 we never actually scaled that far, though.  We 
are now using JRun4 sp1 and cannot get passed 1000 concurrent 
threads/sockets. 

Thanks for your advice, BenG.

High Traffic JRun4 Settings

[Ben Groeneveld]

JRun fans, I am experimenting with high volume settings for JRun under 
IIS.  I seem to bump up against a limit of 1000 user threads open.  I 
have configured the default server SERVER-INF/jrun.xml as follows:

  

1005
500
false
*

1005
1
51000
20
300

At 1000 concurrent connections the jrun server will start complaining 
that I need to configure it for more threads.  I can set the active and 
or max handler threads higher, e.g., 2000, and it has no effect.  When I 
experimented with low numbers, these params normally allow me (N-1) 
concurrent connections, where N is the HandlerThread param.  Now from 
what I understand, each socket connection will hold onto one thread, and 
a VM on NT should be able to handle 2048 threads or so.  Anyone have any 
idea what I am missing?

I don't think IIS is the issue.  But for what it's worth, I have JRun 
connected to IIS5 on win2k server, which is configured to as follows:

100,000 hits per day
ListenBackLog 500
AcceptExOutstanding 200
MaxPoolThreads 20
PoolThreadLimit 2000
ServerListenBackLog 2000
MaxEndPointConnections 2000

Thanks for any advice.  BenG.

Re: help! jrun 3.1 crashing!!!

[Ben Groeneveld]

This may sound simple, but I would suggest divide and conquer.  
You haven't provided any useful information to comment on, so here are 
some very random thoughts.
Isolate the problem.
Try running just the servlet that crashes.
Create a seperate JRun installation to debug on that has no 
modifications other than service packs.

Hope that helps. Thanks, BenG.

native os memory allocator

[Ben Groeneveld]

What would be the advantage of using the os's memory allocator instead 
of the web server's.  Does anyone know what the performance impact is, 
or is this strictly a stability issue? I've searched the documentation 
on this 'advanced' connector option and have found nothing useful 
 Thanks, BenG.

Re: Max Heap Size.

[Ben Groeneveld]

Kannan, before you start changing these parameters wildly, you might 
want to check you memory usage to see what your real bottleneck is. 
1024M is quite high.  JRun has some really nice metrics built in to log 
memory growth.  I would recommend setting Xms and Xms both equal to some 
number like 128 meg so that memory is 'pre-allocated', and turn on the 
collection of memory statistics.  Then you can see if you don't have a 
leak.  What the amount of memory used.  If you do have a leak you can 
get a tool like OptimizeIt (trial available) to help pinpoint it. I've 
tried using a free tool called jmp, but it had some reliability problems 
last time I tried about 6m ago.  Good luck, BenG.

Optimizing JRun4 For Larger Sites

[Ben Groeneveld]

We have an application configured for JRun3 to support up to 500 
concurrent connections (open sockets).  There we're some useful 
documents that helped us get there, in particular MacroMedia's 
"Platform-Specific Performance Settings Article 11772".  What might I 
find useful for JRun4 tuning?  Currently I am wading through the pdf's, 
and just came across the HtmlAgentService to set all parameters in the 
jrun.xml file.  But, some recommendations or references for large 
installations would be useful.  Thanks, BenG.

Inconsistency Iisue with jvm.conf and admin console "Settings

[Ben Groeneveld]

This looks like a bug.  We are running JRun4 no service packs (because 
sp1 doesn't completely install). In our bin/jvm.conf we have 
pre-allocated memory:

java.args=-Xmx128M -Xms128M

But, the admin console will display only the second param as:

-Xms128M

So, using the admin console you think something is missing ...  so you 
add more params and provide the jvm with conflicting instructions. 
 Anyone else seen this?  Thanks, BenG.

Re: How To Browse Virtual Dirs In JRun4

[Ben Groeneveld]

  Charlie, I came up with something that satisfies my current needs, but 
I would hope there is a more fail-safe approach. Essentially I turn the 
generic browse switch for the default server on, add my virtual mapping, 
and then turn off browsing specific to my app's war.  It's like the 
reverse of what you do for security.  Imagine in your /etc/hosts.allow 
you permit all access, then one by one plug the holes...  Thanks for the 
followup, BenG.


   (a) 
$CONTAINER_DIR/servers/default/default-ear/default-war/WEB-INF/jrun-web.xml

   
   /logs/*
   $CONTAINER_DIR/logs
   

   (b) $CONTAINER_DIR/servers/samples/SERVER-INF/default-web.xml 

   
  FileServlet
  jrun.servlet.file.FileServlet
  
  browseDirs
  true
   
   

   (c) In the web.xml for the .war's that you deploy add: 



  browseDirs
  false

FileServlet
jrun.servlet.file.FileServlet
This servlet overrides FileServlet in 
SERVER-INF/default-web.xml.

How To Browse Virtual Dirs In JRun4

[Ben Groeneveld]

How do I tell JRun4 to permit directory browsing in a specific 
directory, like the following dir defined  in my jrun-web.xml file?


  
/logs/*
/usr/local/JRun4/logs

Issues with XML and JRun4

[Ben Groeneveld]

I've been trying to use jdom8.jar with xerces.  I tried using the 
builtin jdom7 with crimson, but kept getting an error regarding a null 
constructor for the SAXParser.  However, my code works as desired after 
taking the following drastic measure, i.e., replacing and modify the 
jrun.jar.  I updated jrun.jar with jdom and xerces as follows:

   jar xvf jdom.jar
   jar xvf XmlParserAPIs.jar
   jar xvf xercesImpl.jar
   jar -uf jrun.jar 'JDOMAbout$Author.class' 'JDOMAbout$Info.class' 
JDOMAbout.class javax org

I thought I should have, but I could not get any of the following to 
work. For each of these I essentially get a ClassNotFoundException for 
the SAXParser.

- put the jars in my CLASSPATH, or in JRun4/lib, or in 
JRun4/servers/default/myApp/WEB-INF/lib
- expanding the jars into myApp's war path WEB-INF/classes

Although everything seems to work fine for me now, I'm sure messing with 
jrun.jar is not kosher, especially with regard to support and patches, 
etc.  What would be the right way to do this?  

Thanks, BenG.

Trouble With JRun4, ColdFusionMX, And IIS Coexistence

[Ben Groeneveld]

We used to do this before JRun4 and *MX, but now we are upgrading and 
cannot seem to get the three to live together happily.  We have run the 
JRun4 web config tool, and my CF peer has done the equivalent for CF. 
 Now when I try to open a jsp on port 80 (that works fine on port 8100) 
I get the following (from the CF jvm).  Of course, we have checked our 
licensing and believe all is properly configured.

License Exception has been thrown

I can see that the JRun isapi filter is at least being invoked, because 
the IIS connector log lib/wsconfig shows this (status.jsp is what I can 
get at on port 8100 but not 80):

16:00:45 jrISAPI[init] jrISAPI[filter]: scriptPath is /JRunScripts/jrun.dll

I've tried both the normal web connector settings as well as the 
advanced where you select the extension to be invoked.  Any clues or 
insight would be useful.

Thanks, BenG.

Re: Potential JRun 4 getPathInfo Migration Issue

Yes, our pattern was /TestServlet and changing it to /TestServlet/* 
resolves the issue.  Thanks!  BenG.

Potential JRun 4 getPathInfo Migration Issue

[Ben Groeneveld]

I am having trouble migrating a servlet that uses request.getPathInfo(). 
 We use a URL like:

http://127.0.0.1:8100/tJRun4/TestServlet/extraParams?misc=stuff&more=NotEnough

I developed a little testcase which presents the above as follows on 
JRun 3.0:

doGet
logRequestParameters request.getPathInfo(): /extraParams
logRequestParameters request.getQueryString(): misc=stuff&more=NotEnough
logRequestParameters request.getPathTranslated(): 
C:\usr\local\jrun-3.0\servers\default\tJRun4\extraParams
logRequestParameters request.getRequestURL(): 
/tJRun4/TestServlet/extraParams
logRequestParameters request.getParameterValues(): misc:[stuff]
logRequestParameters request.getParameterValues(): more:[NotEnough]

On JRun 4 I just get in the log:

error Requested resource /tJRun4/TestServlet/extraParams not found

Anyone have a clue as to what's up or what we're doing wrong?  Thanks, BenG.

Re: Storing xml in oracle 8i

[Ben Groeneveld]

Verma, you could map the file directory to your web server, then it 
could be served to anyone to whom you provide access.  But that may not 
be what you are looking for.  Hope that helps, BenG.

Re: Storing xml in oracle 8i

[Ben Groeneveld]

Verma, if you are looking for performance, consider storing your large 
objects outside of oracle directly on the file system.  You can store a 
reference to the file in oracle.  Filesystems are pretty good at serving 
large stuff quickly - works great for us!  Hope that helps, BenG.

Re: Java/Excel

[Ben Groeneveld]

Kans, I have found that the easiest way to do this is to simply alias 
your jsp or servlet to somename.csv.  Then, if you just return a file 
with comma separated values, your IE will open MSExcel as an OLE thingy. 
 Netscape will may prompt you.  So, like this in your web.xml:


Sql2Csv
/forms/sql2csv.jsp


Sql2Csv
/forms/sql2csv.csv



When IE sees that the file type of .csv it loads the results into Excel. 
 So it *only* works if your URL ends with .csv, so you must POST if 
parameters are needed.  You just need to write the csv to the stream (in 
jsp out.print()).  To help Netscape you can add content type like so:

<%@ contentType="application/vnd.ms-excel"
%>

There are fancier ways to do this with XML as the so called pet shop 
examples show.  However, I like the KISS principle.  Hope that helps, BenG.

Re: help! Datasource!

[Ben Groeneveld]

Zafif, this is the case here.  We are doing some JNI and when we hose 
the system up such that jrun.exe won't exit, even though the vm is gone, 
but you try and start up a new instance anyway, the symptom reported in 
the log is

Port in use by another service or process: 53000

so I think your hypothesis is right on.  BenG.

Re: Connection reset by peer: socket write error

[Ben Groeneveld]

What's JRun's Oracle driver?  Have you tried using oracle's free thin 
driver?  We use oracle JDBC driver-8.1.6.2.0 on a large variety of 
projects and operations w/o a hiccup.  Maybe trying it will help you.  BenG.

Re: Background Thread Servlet Question

[Ben Groeneveld]

Alex, you can specify in the web.xml for the servlet to autoload when 
the container starts, and then start the threads in the init method.  To 
track your threads, first create a threadgroup, and start all your 
threads in that group.  Name each one, and then use a tool like 
OptimizeIt to track them.  OptimizeIt attaches nicely to a jrun 
container.  Be careful starting too many threads, you'll shoot yourself. 
 Most people don't realize they don't need 'em :)  Hope that helps, BenG.

Re: Difficult To Reproduce Session Issue

Scott, easy for you to say...and I would have done that were it 
critical. Instead, it's not.  Merely frustrating for me because it deals 
with a sys admin component of our system the customer never sees.

You know I have provided you with a test case of a bug before and you 
just sat on it.

How about offering some constructive debugging tips for this difficult 
issue instead?  

Thanks, BenG.

IIS authentication 'under' jrun

[Ben Groeneveld]

Hi, I'm looking for some iis/jrun integration advice.  We have a jrun 
3.0 app that uses form based authentication.  Nice because we can 
generate 100s of passwords in batches using pwgen and jrunpasswd.  Now 
we have the need to integrate with crystal reports under iis4 on nt4. 
 We would like to bring these crystal iis 'pages' under the jrun realm, 
which is defined in our web.xml.  I tried using a virtual mapping, but 
that doesn't work because the crystal reports use some sort of isapi 
(I'm not too familiar with this) filter that tell it to generate epf 
(encapsulated postscript, btw, pretty fancy if you haven't seen it). 
 Adding mime types to global.properties was apparently not enough.  Not 
being too knowledgeable on NT/IIS security - is there an easy way to 
accomplish this?  Note that we absolutely do not want to use an IIS/NT 
gui to admin 100s of users, so if the solution is to have IIS control 
authentication, I would gladly hear about some way to import gobs of 
user credentials.  Help is greatly appreciated.  Thanks, BenG.

Re: Why HTTP tunneling not working in Netscape?

[Ben Groeneveld]

Susan, there can be a number of things up.  Proxies and persistent 
connections can wreak havoc with the URLConnection class.  In your case 
the POST may not actually be happening.  These two articles helped me a lot:

http://www.javaworld.com/javaworld/jw-03-2001/jw-0323-traps_p.html
http://www.javaworld.com/javaworld/javatips/jw-javatip34.html

Also, a great new feature for those of us using URLConnection instead of 
sockets (which I still prefer) is that with 1.4 you can specify a read 
timeout (albeit using a property)!  Hope that helps, BenG.

Re: Starting JRun Servers as Service

[Ben Groeneveld]

Dan, you add it to your local startup script, usually an rc.local, or 
create a startup script by cloning one of the many in /etc/rc.d/init.d 
if you are running a sysv unix like red hat linux (maybe macromedia will 
soon ship a template like other vendors). After cloning you use a 
utility like chkconfig to ensure the new script fires up at the 
appropriate run level by creating some symbolic links.  Hope that helps, 
BenG.

Re: JRUN Startup and Shutdown Settings????

[Ben Groeneveld]

Alex, you may look into the init method of a servlet that is designated 
to be loaded on container startup by the web.xml, and use the destroy 
method of the same servlet.  Hopt that helps, BenG.

Difficult To Reproduce Session Issue

[Ben Groeneveld]

Hello.  I seem to have a difficult to reproduce session issue.  I am 
loosing session attributes on occasion, and it seems to be related 
(although not for sure) to concurrent use of ie 6 with a java applet 
that connects to the server for db interaction.  Odd thing is that it is 
not immediately after one of those events - only after several more 
client/server interactions.  It seems like I get a new session.  All my 
forms and servlets communicate with the same database, whose jdbc 
connection information is stored with that user's session - so when my 
session gets lost I will see messages like:

02/08 16:19:26 error (JRun) exception.jsp: message:Can only use 'connection' or 
'datasrc' or 'driver + url'. trace:allaire.taglib.InvalidTagAttributeException: Can 
only use 'connection' or 'datasrc' or 'driver + url'. 
[allaire.taglib.InvalidTagAttributeException: Can only use 'connection' or 'datasrc' 
or 'driver + url'.]
allaire.taglib.InvalidTagAttributeException: Can only use 'connection' or 'datasrc' or 
'driver + url'.
at allaire.taglib.SqlTag.validate(SqlTag.java:100)
at allaire.taglib.SqlTag.doStartTag(SqlTag.java:168)


Can someone clue me in on what this might be - or I'm even up for some 
good debugging ideas?  I am using jrun 3.1 patch level 26414 on redhat 
7.1.  Thanks, BenG.

Re: Installation on Linux

[Ben Groeneveld]

David, I had the same problem on 7.1 and wound up copying the binaries 
from a successful 6.2 install.  But then, patch 26414 seems to install 
fine, which is apparently a complete install.  Maybe give that a try; 
find it by searching the knowledge base at the support site.  Hope that 
helps, BenG.

Funny, I did exactly what you did in terms of altering the script and 
eventually ran into checksum errors.  I thought it was me.

Re: LongTexts

[Ben Groeneveld]

Fred, this sounds related to msaccess and not JDBC.  I regularly update 
oracle text fields via JDBC that are 3200 wide.  Maybe see if there 
isn't another datatype you can use.  Hope that helps.  BenG.

Re: netstat, grep, etc

Jeff, you are so right.  But one really nice things about NT is the 
performance monitor.  It is just indispensable in system testing.  Are 
you aware of any such comprehensive system data collection tool for 
unix?  I've been on unix for ages and still fiddle with various scripts 
and utils.  Thanks, BenG.

Re: JVM and Red Hat 7.2

Renato, download from www.ibm.com/java

bruce:~> java -version
java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0)

Regarding comments on the 1.4 beta - for what it's worth the plugin 
frequently freezes my IE on win32 running Oracle applets.  But then I 
haven't tested IBM's plugin there.  The IBM jdk on win32 also shows 
observable and measurable performance improvements over Sun's 1.3. BenG.

Re: Page cannot be displayed

[Ben Groeneveld]

Arul, this might be due to buffering.  This went away for me when I used 
Apache as the external web server, and for the JRun web server when I 
manually set the buffer size, like so in the jsp:

<%@ page 
 buffer="32kb"
 autoFlush="true"
 language="java"
 import="allaire.taglib.*, java.sql.*" %>

Hope that helps, BenG.

Re: SV: JRun does not responds after 100 threads

[Ben Groeneveld]

Roar, unless you make special provisions each servlet request would be 
another thread.  Could it be that your threads (requests) are not 
exiting but blocking on some resource?  Can you throttle demand for that 
resource by including a synchronized method wrapped around that 
resource?  Just a thought.  BenG.

Re: JRun does not responds after 100 threads

Makarand, are you hitting JRun thru the Netscape Webserver?  Then your 
problem may be with its max concurrency setting.  I have seen this with 
IIS as the front-end to JRun.  How many concurrent connections will your 
Netscape Webserver accept?  Make sure you are updating the external web 
server settings and not the JRun web server.  Hope that helps, BenG.

Re: JRun does not responds after 100 threads

[Ben Groeneveld]

More to ponder...I repeated this run on my laptop now booted in
redhat 6.2.  I change the JRun web server min threads from 1 to
50, and change the idle thread timeout from 300 to 60s.  Now I
fire up the JRun 3.1 default server.  I check gtop, and I see
jrun having 95 processes (a linux thread is practically a
process).  60 seconds later this number drops to 46.  Hmm.  That
doesn't seem right.  It should be threads beyond the pool of 50
that get killed.  Ok, so now I set the min threads back to 1,
restart, and JRun default has 44 threads.  Now all these threads
are idle, none are vying for CPU.  I have a hard time accepting
this as thread-thrashing or NT vs unix. These are the exact same
results I see on NT for JRun 3.0 sp2.  I think the thread pool's
not working, or I don't understand these parameters.  What am I
missing?  Thanks, BenG.

Re: JRun does not responds after 100 threads

[Ben Groeneveld]

Dave, agreed that 100 threads is a lot, but only if they are all busy. 
 From a unix perspective, the main thing to worry about is that the 
average queue length in front of the cpu - aka load average - is < 1. 
 As long as this is well below 1 there should not be 'thread thrashing' 
on a single headed machine, don't you think?

For example, in my experiments on NT we see JRun's VM consuming about 
100 threads (because our clients keep their sockets open, but the 
threads are largely idle).  NT and other processes account for an 
additional 4-500 threads, but CPU utilization is just some 15%.  I can 
monitor page faults as well and they stay at just a couple per second. 
 I'm having a difficult time attributing the thread 'loss' to something 
else than a bug...

Thanks, BenG.

Re: JRun does not responds after 100 threads

[Ben Groeneveld]

Makarand, I have seen similar behavior.  I think there may be a JRun problem.  If I 
setup a threadpool of 50 with an idle thread timeout of 60, then after a fresh jrun 
startup and no activity NT perfmon shows the threadpool gets cleaned up.  Or if I send 
a burst of 100 persistent connections, then after 60s the threadcount goes from 150 to 
100.

I am going to try an experiment with the IBM jvm later this week to make sure this 
isn't VM related.

I've had best performance leaving the threadpool at 1, even thought that's not what's 
desired, my server/VM lives much longer that way.  I'm assuming that changing the 
threadpool causes a fault inside JRun.  Anyone know more?

John, thanks.  I was hoping to not introduce yet another passwd

Re: JRun 3.1 connector disables SSI

[Ben Groeneveld]

Scott, the goal is to have apache work the way it used to before jrun 
was connected.  jrun interferes with the ssi handling as far as I can 
tell.  If I turn off jrun's .shtml handling then .shtml in the apache 
server root still doesn't work unless I rm the mod_jrun.  

I have found a workaround.  Using the apache 'xbithack on' directive I 
can cause std .html files to be parsed for ssi if their file mode is +x. 
  I also rename my files from .shtml to .html for this to work.

I don't have evidence of anyone else seeing this issue, but would like 
to.  it's easy to reproduce.  The default redhat config for apache is to 
recognize ssi.  I'm running jrun 3.1 on redhat 6.2 with apache 1.3.14.  

Thanks, BenG.

Re: JRun 3.1 connector disables SSI

[Ben Groeneveld]

Scott, thanks.  I would like to have it on in my apache html tree.  But 
the mod_jrun seems to disable it.  BenG.

Re: JRun 3.1 connector disables SSI

[Ben Groeneveld]

Victory cry too soon!

Just when shtml is working the mod_jrun stops, if I get mod_jrun to run 
by placing it before includes_module then shtml stops...

Any help appreciated.  Thanks, BenG.

Re: JRun 3.1 connector disables SSI

[Ben Groeneveld]

John, SSI becomes disabled for all files in the apache 's.

By default JRun loads their module after all others when auto-installed 
by the JRun admin console.  So this is interesting: I just tried loading 
the JRun module first.  *This works*.  I put it back at the end of the 
httpd.conf and SSI stops working.  Order matters.  Thanks

As an aside, I would also like to be able to control access to the paths 
mapped by jrun using .htaccess or AuthUserFile, but it seems that they 
get intercepted first by the mod_jrun.  Do you know of a way around this?

BenG.

JRun 3.1 connector disables SSI

[Ben Groeneveld]

Hooking up my JRun 3.1 to Apache 1.3.14 on RedHat 6.2 disables server 
side includes (.shtml).  It is easily reproducible.  Has anyone else 
seen this - is it a known problem with a workaround?  Thanks, BenG.

what is "Exception while swapping" ?

[Ben Groeneveld]

In an attempt to debug what appears to be a lockup we turned debug on in 
logging.  One thing we see is this:

08/07 16:04:43 info (JRun) f_req_drw_Servlet.doGet END

maintain keepalive.
08/07 16:05:10 info (JRun) f_req_drw_Servlet.doPost BEGIN

Re: Setting Blob and Clob data in Oracle from an EJB.

[Ben Groeneveld]

Depending on your application, consider storing the blobs directly on 
disk.  Filesystems can be efficient and fast.  Just keep a reference to 
them in oracle.  BenG.

Re: bean newbie question

[Ben Groeneveld]

That's interesting, we do just the same but with CVS.  I'm curious, do 
you use makefiles for your build or have you come across a better tool? 
 Makefiles have been nice in that we can build from the same repository 
on linux and windows using cygwin.  BenG.

Re: Newbie question/Debate

[Ben Groeneveld]

Bear in mind that's it's not so 1-2-3 as you make it sound. It is my 
understanding from the developer of the cobol .net compiler for hitachi 
that you must code in a proper subset of the language.  I think that if 
you want to use .net you are best coding in its native language c#.  BenG.

Re: Newbie question/Debate

[Ben Groeneveld]

One of the nice things I like is my ability to adjust and scale.  In my 
current project I am just butting up against 2gbyte file limits on std 
32bit intel linux.  I know I can easily upgrade to a pay-for-unix, get 
huge files, and don't have to worry about my apps written in 
java/servlet/oracle.  BenG.

Re: Servlet request object and multipart/form-data

Yes, the oreilly package is great.  The only limitation we found is the 
upload size being checked with a Java int which limits the size of 
uploads to 2G...  BenG.

Re: JRun 3.1 Stability

[Ben Groeneveld]

Alpesh, we have most definately run into problems with jrun 3.1 
configured with jdk 1.3.1 and Oracle 8.1.6 on radhat 6.2.  SQL UPDATE 
statements don't work in the jrun:sql tag.  I would like to report this 
to Allaire because I've narrowed this down quite well, but they want 
your credit card to report bugs - so they suggested I report it to this 
list.  I have reported this issue 6/15:

jrun 3.1 sql tag issues

[Ben Groeneveld]

Has anyone else seen these issues when upgrading to 3.1?

(1) 'update' statements fail to be parsed and run in the jsp:sql tag 
resulting in an out of memory message
(2) the sql tag scripting method .resetCursor() vanished and must be 
replaced with .beforeFirst(), a java.sql.rowSet interface
(3) the parser is much more sensitive to requiring scripting parameters 
be enclosed in double quotes, but that's probably a good thing.  
however, the line numbering info it returns is useless

I haven't found a workaround to (1) so if anyone has please let me 
know.  Thanks, BenG.

bad magic number on NT crash

[Ben Groeneveld]

We seem to have a recurring problem with java servlet classes getting 
corrupted when NT gets shutdown ungracefully.  A recompile always solves 
the problem, but that's a big hassle.  I was wondering

(1) does anyone else have this problem?  a note is that our linux based 
servers don't see this and are using the same rev of JRun (3.01) and 
JDK(1.3).
(2) can I mitigate this by turning off any sessions or other objects 
JRun is trying to recover?

The log below is from jrun/logs/default-event.log.  The errors occurs on 
a jsp (f_req_maint) that is forwarded to from a servlet 
(f_req_maint_Servlet).  The jsp loads a bean, but it doesn't get that 
far.  Thanks, BenG.

conversion of "<" to "<"

Another conversion question - is there a class that can do these html 
safe conversions:

"<" represents the < sign
"&" represents the & sign
"" represents the " mark

Bad magic number - known jvm issue?

[Ben Groeneveld]

This may not be a JRun question, but I wonder if you have seen this.  We 
had a 500 internal server error on a "Bad Magic Number", which was fixed 
by recompiling a servlet class that has become corrupted.  This seemed 
to have happened after out NT server was hit by a power outage.  I've 
seen this before on another NT server that on occasion, when not shut 
down gracefully, would have currupted files with bad magic numbers.  
That machine just ran straight Java code w/o JRun.  We also run linux, 
where I have not seen this.  Is there some known issue about class files 
getting corrupted (on NT?) when a JVM is not shutdown gracefully?  
Thanks, BenG.

Re: Beans reload problem

[Ben Groeneveld]

It is, confirmed by Allaire a while back when I asked the same.  I've 
heard many containers have this problem.  It's unfortunate, because I 
put a lot more code in my JSPs than I'd like too, because this is faster 
than developing beans.  Does anyone know which containers do not require 
this restart, e.g., Tomcat?  Thanks, BenG.

Re: How To Increase JVM Size

[Ben Groeneveld]

pdw, you are exactly right.  I can now use (for limit testing, 'man 
java' says the defaults are 8m and 24m)

   user.javaargs=-Xms8m -Xmx8m

And to see the command line, since it's so frikken long, use 'ps -ef 
--width 254'

Also, I really like the idea of setting min size = max size for 
servers.  I'm using a custom cache in our system, and by specifying 
these limits it seems I can insulate better from other processes' troubles.

Thanks, BenG.

Multiple servers - bind: Address already in use

[Ben Groeneveld]

Victor, I read you posting regarding issues running two jrun servers on 
a machine.  Did you ever get any response?  For some reason I can no 
longer post to the newsgroup.  Anyway, I've managed to get two jrun 
servers going on my redhat6.2 box, one for production and one for 
development.  Only the production instance is linked to apache - I got 
socket address bind errors when I tried two.  So we access deveopment 
directly from it's web server port.  I changed all port numbers to be 
separate (+=10) as is evidenced by the diff below.  Now occasionally, 
web clients cannot access the development server - essentially they need 
to do a refresh before they can hit the page.  I see this message in my 
/var/log/messages file:

Mar 21 06:55:38 penguin inetd[424]: auth/tcp: bind: Address already 
in use

Any clues as to what this might be?  Thanks, BenG.

[Fwd: servlet debugging]

Please let me clarify.  My issue is actually with a bean my .jsp's 
uses.  The bean is not reloaded after I recompile it.  Should it be?  
Thanks, BenG.

What's a good way to have servlets auto-reloaded when recompiled?  I 
looked though the manual and this was not obvious.  When I change a .jsp 
jrun seems to detect that and reload, but servlets don't (I'm using the 
invoker servlet shortcut).  What am I missing?  Currently I restart the 
default jrun server to debug, but this is painfully slow.  Thanks, BenG.

shut everything down but studio my cpu is still pegged.  I've stopped 
using the product, which is unfortunate - because I liked it.  Good 
thing for demos...  BenG.

RE: servlet debugging

[Ben Groeneveld]

Scott, thanks for responding.

At 01:14 AM 12/31/00 -0500, you wrote:

Our servlets are located in jrun/servers/default/myapp/WEB-INF/classes, 
which is not in my CLASSPATH; I don't think they should be.  The 
application is installed using makefiles, so we make use of the command 
line deploy and remove capabilities.  We use makefiles because our app is 
developed collaboratively, geographically speaking, via cvs.  We currently 
debug using the jrun event logging (jrun/logs) accessible from the servlet 
"context."

We're using jrun 3.01 on redhat 6.2 with jdk 1.3 and oracle on the back 
end.  The config is standard I think, as described above.  Any help is 
welcome.  Restarting the server each run is slow.

Thanks, BenG.

servlet debugging

[Ben Groeneveld]

What's a good way to have servlets auto-reloaded when recompiled?  I 
looked though the manual and this was not obvious.  When I change a .jsp 
jrun seems to detect that and reload, but servlets don't (I'm using the 
invoker servlet shortcut).  What am I missing?  Currently I restart the 
default jrun server to debug, but this is painfully slow.  Thanks, BenG.

Re: JSP hosting

[Ben Groeneveld]

Scott, Evan gave me the referenced list below which lists primarily CF
partners - not yet useful to me.  I am still working with him to get
a list of JRun hosting firms; he has not yet responded to my followup,
which he normally has been very good about.
I would agree with your statement; I have already received several responses
with links to JSP hosting firms not on your list - perhaps because they
are not "partners": cniweb.net (Tomcat), hostjsp.com, and www.senternet.com.
Thanks, BenG.

Ben,

I have done some digging for you in regards to Jrun Hosting.  I have
included a link below where you can take a look at the different companies
within the U.S. which host Jrun.

JSP hosting

[Ben Groeneveld]

Can someone recommend a JSP hosting service?  JRun hosting preferred,
but other containers may work too.  In speaking with Allaire sales no
hosting services could be recommended. Thanks, BenG.

Re: jsp tag library

[Ben Groeneveld]

It took me a while also.  Did you add your jdbc drivers to the default
*and* admin servers and verify they work?  The drivers for your db
go in lib/ext to be auto picked up.  Then, I modifed the source of
the examples to go against tables that really exist in my db.  BenG.

Re: Overwriting of deploy.properties

[Ben Groeneveld]

Adam, I've been using makefiles and command line deploy to avoid use of a properties 
file
altogether.  For me this is an easier way to do system builds platform to platform.  
Our
app is named doms.  Maybe this will help you:

CONTAINER_DIR  = /usr/local/JRun

DEPLOY_SERVER_NAME = default
DEPLOY_SERVER_DIR  = $(CONTAINER_DIR)/servers/$(DEPLOY_SERVER_NAME)

DEPLOY_APP_NAME= doms
DEPLOY_APP_DIR = $(DEPLOY_SERVER_DIR)/$(DEPLOY_APP_NAME)

DIRS   = $(DEPLOY_APP_DIR)

all:  doms.war

doms.war:
 jar cvf0M doms.war index.html WEB-INF

deploy: $(DIRS) all
 cp doms.war $(DEPLOY_APP_DIR)/
 java -classpath $(CLASSPATH):$(CONTAINER_DIR)/lib/jrun.jar \
  allaire.jrun.tools.WarDeploy -deploy \
  deploy.war.path=$(DEPLOY_APP_DIR)/doms.war \
  deploy.server.name=$(DEPLOY_SERVER_NAME) \
  deploy.webapp.name=$(DEPLOY_APP_NAME) \
  deploy.context.path=/$(DEPLOY_APP_NAME) \
  deploy.webapp.rootdir=$(DEPLOY_APP_DIR) \
  deploy.jrun.rootdir=$(CONTAINER_DIR)

remove:
 java -classpath $(CLASSPATH):/usr/local/JRun/lib/jrun.jar \
  allaire.jrun.tools.WarDeploy -remove \
  deploy.server.name=$(DEPLOY_SERVER_NAME) \
  deploy.webapp.name=$(DEPLOY_APP_NAME) \
  deploy.jrun.rootdir=$(CONTAINER_DIR)

$(DIRS):
 -mkdir -p $(DIRS)
