Re: JRun 4 (Build 59056) - jsp:include error
Where do you put your servlet? I remember in Jrun 4.0,
you only need to put your servlet in your classes
folder.

RE: Problems with JSPs finding packaged classes
Erik,
Thank you so much for your info. I am going to try
this out. It took me a day to unsuccessfully work on
this issue.

We ran into similar issues (with respect to JRun 4
not finding the contents
of the Jar files), but in regards to tag libraries
not loading in when the
.jar file was in the server instance's WEB-INF/lib
directory.We fixed
this problem by adding the classpath to the lib
directory manually to the
java.class.path of the JRun instance we were going
to start up.For some
reason, JRun would find maybe the first JAR file in
the lib directory
(without this), but then none of the others.Now,
it finds them all (???)
So, here's an example:
$JRUN_HOME=/opt/java/jrun4
server instance: jsm-foo
In
$JRUN_HOME/servers/jsm-foo/default-ear/default-war/WEB-INF/lib
directory,
we have:
mail.jar
taglibs-scrape.jar
jstl.jar
...
We start each server instance off individually (to
avoid single point of
failure), and the only way to do this is to place a
configuration file into
your $JRUN_HOME/bin directory (with the classpath
for the instance).So,
we'd have a:
(in $JRUN_HOME/bin):
jsm.foo.conf:
#
# VM configuration
#
# Where to find JVM, if {java.home}/jre exists then
that JVM is used
# if not then it must be the path to the JRE itself
#
# If no java.home is specified a VM is located by
looking in these places in
this
# order:
#
#1) JAVA_HOME environment variables (same rules as
java.home above)
#2) bin directory for java.dll (windows) or
lib/ARCH/libjava.so (unix)
#3) ../jre
#4) registry (windows only)
#
java.home=/usr/jdk1.4
# Arguments to VM
java.args=-Xms65M -Xmx300m -Djava.awt.headless=true
# java.class.path - use this for adding individual
jars or
# directories.When directories are included they
will be searched
# for jars and zips and they will be added to the
classpath (in
# addition to the directory itself), the jar to be
used in launching
# will be appended to this classpath
java.class.path=/opt/java/jrun4/servers/jsm-foo/default-ear/default-war/WEB-
INF,/opt/java/jrun4/servers/jsm-foo/default-ear/default-war/WEB-INF/lib,/opt
/java/builds/foocode
#
# where to find shared libraries, again use commas
to separate entries
java.library.path=
I don't know if the first entry to the WEB-INF is
needed, but the second one
makes mention to the lib directory.Also, the
foocode would contain our
jars and zips.
To start this instance up, cd to $JRUN_HOME/bin and
start it up:
sudo jrun -config jsm.foo.conf -nohup -start
(using Solaris 8 JRun 4 - for Windows, you can get
rid of the 'sudo'
command).
Anyway, hope this helps.If it doesn't, you might
also try the newsgroups
(since this email list is pretty much dead).I go
to
http://groups.google.com and search from there.
Good luck.

RE: Compiled Java Files from jsp's
1. JRun 4.0 In your app default-web.xml, check init-param for JSPServlet. If you need to have source files generated, use: init-param param-namekeepGenerated/param-name param-valuetrue/param-value /init-param 2. JRun 3.0 Jrun 3.0 will generate those source files by default. All source files are in the same directory as byecode files as Dave said. fyi.

We deploy a webapp in it¹s expanded form to a folder like /apps/app1¹ and then use the JRun admin interface to point to the directory and deploy the application. Turns out we have some run time errors in some JSP files that give the line number for the exception for the COMPILED JSP but not the actual JSP file on disk. I don't think it stores the source files at all - I think they're compiled directly to bytecode without being stored as source code. I'm no JRun expert, though. If they were stored anywhere, I suspect they'd be stored in the same place as the compiled class files. I think the compiled class files are in \jrun4\servers\yourserver\yourserver-war\WEB-INF\jsp (if you've deployed as an EAR, presumably it would be \jrun4\servers\yourserver\yourserver-ear\yourserver-war\WEB-INF\jsp Dave Watts, CTO, Fig Leaf Software http://www.figleaf.com/ phone: 202-797-5496 fax: 202-797-5444 [Todays Threads] [This Message] [Subscription] [Fast Unsubscribe] [User Settings] [Donations and Support]

We are running Jrun 4 in solaris 5.8. Each Jrun app server instance uses abount 30MB-35MB without servicing any requests.

As an Admin, I am trying to determine if I should create seperate CFMX instances for each App or should I actually put some thought into it. ;-) I wouldn't base this decision on memory usage. You should ask yourself what benefits, if any, you'll see by running separate applications on separate instances. For example, you might benefit by isolating stable applications from unstable ones, or by being able to secure individual applications better, or by being able to tune individual applications better.

Its a pretty complete set of documentation to get your own service up and running. A word of caution.

Re: JRUN Stability- reply 2
Ben, How is the stability and performance of JRun server after you set activeHandlerThreads to 2000? Usually the number of the maxHandlerThreads should be bigger than activeHandlerThreads? As I understand, JRun would not perform well if the number of activeHandlerThreads is too big. Could you share your experience here? How busy would the traffic be on your site and is your site running in UNIX box? Thanks.
