If you run your WebLogic on Win2K, you have to modify the
command file startWebLogic.cmd

Classpath, weblogic.class.path, server's class path, javaclasspath, serverclasspath ?? confused

When I type t3config , I see a couple of class paths and I'm confused which
one is which and
what are the diffrences between them, there is classpath, javaclasspath,
serverclasspath, weblogic.class.path
and JVM class path, Server's class path on the weblogic console window.
any clearification is appreciated.
thanks,
CLASSPATH Prefix
CLASSPATH
JAVA_HOME
WEBLOGIC_LICENSEDIR
WEBLOGIC_HOME
system properties
weblogic.class.path
INITIAL HEAP
MAX HEAP
SERVERCLASSPATH

Why would you do that - same class in both class paths? Don't.
Don't put any application classes in the system
classpath (JAVACLASSPATH).

Weblogic.class.path

I am using WL 5.1, SP12, on Solaris ...
          I am running jsp code that accesses a bean class specified in the weblogic.class.path in my startscript.
          I got a "ClassNotFound" error when I run the jsp code.
          Are all classes in weblogic.class.path of a given WL server visible to JSPs running in that server - regardless web-applications?
          I appreciate any help. Thanks


Look at startWeblogic.{cmd/sh}.
WLCLASSPATH should include the weblogic classes and any of your classes.
JAVACLASSPATH include the JDK classes, the weblogic/classes/boot and DB
access classes
(Cloudscape.jar, JConnect classes, etc.) and NOTHING else.
"Shoaib" <[email protected]> wrote in message news:[email protected]..
The documentation on setting up the environment mentions this property
but doesn't give any information on where it should be set.
How is this system property specified and what is it used for ?
Should it be specified via wlconfig.exe or is included in
weblogic.properties ?
I'm currently using the latest beta for WLS.

Diff between CLASSPATH and weblogic.class.path in t3config

Hi,
          My servlets which would run happily in WLS4.0.2 on NT do not run anymore
          in WLS4.5.

Pankaj,
          It all depends on whether you want to do reload on modify feature or not. If you don't need reload on modify they you can have servlets in weblogic.class.path.
          Two things to remember if you can't invoke servlets.
          1. Do you have the servlet registered.
          2. If not, do you have ServletServlet property uncommented. If this property is not commented out then you have to give the complete path to make servlets work.
          Good luck,
          Prasad

How to set (class)paths for a Managed server?

How does one configure the PATH and CLASSPATH and pass definitions (like "-Djava.library.path=c:\p\bea\wlserver6.1\bin")
to a remotely-started managed server?
The section in the WLS 6.1 AdminGuide.pdf that talks about configuring a managed
server's Remote Start tab says on pages 3-9 to 3-10 that, "If you don't specify
values for these fields and attempt to start the target server from the Administration
Console, the Node Manager will attempt to start the target server with the values
for these attributes that were used when starting the Node Manager. The Node Manager
will be able to start the Managed Server in that case if you specified the required
values on the command line when starting the Node Manager."
So it sounds as if I can get the java.library.path definition and CLASSPATH sent
to the server via the Node Manager startup command.
Does that work when using the Node Manager as an NT Service? Here is my Win2K
command file for setting up the Node Manager as an NT Service. Note that I'm trying
to tell it where to find the Windows native libraries (wlserver6.1\bin for wlntio.dll)
and the JDBC drivers (C:\SHADOW\jdbc\... and C:\Orant\jdbc\... ) :
========== BEGIN installNMNtService.cmd ================ @echo off
SETLOCAL
cd C:\p\bea\wlserver6.1\
rem *** Set Classpath to load Weblogic Classes
set CLASSPATH=.;C:\p\bea\wlserver6.1\lib\weblogic_sp.jar;C:\p\bea\wlserver6.1\lib\weblogic.jar;C:\SHADOW\JDBC\scjd12.jar;C:\orant\jdbc\lib\classes111.zip
rem *** Set Command Line for service to execute
rem *** %JAVA_HOME%\java will automatically be prepended.
set CMDLINE=" -ms16m -mx16m -classpath \"%CLASSPATH%\" \"-Dbea.home=C:\p\bea\"
\"-Djava.security.policy==C:\p\bea\wlserver6.1/lib/weblogic.policy\" \"-Dweblogic.nodemanager.weblogicHome=C:\p\bea\wlserver6.1\"
\"-Dweblogic.nodemanager.reverseDNSenabled=true\" \"-Djava.library.path=c:\p\bea\wlserver6.1\bin\"
\"-Dweblogic.nodemanager.listenAddress=111.111.111.123\" \"-Dweblogic.nodemanager.trustedHosts=./config/nodemanager.hosts\"
weblogic.nodemanager.NodeManager"
rem *** Install the service
"C:\p\bea\wlserver6.1\bin\beasvc" -install -svcname:EDANodeManager -javahome:"C:\p\bea\jdk131"
-execdir:"C:\p\bea\wlserver6.1" -extrapath:"C:\p\bea\wlserver6.1\bin" -cmdline:%CMDLINE%
ENDLOCAL
================= END installNMNtService.cmd ==================
But when I start a server remotely, it can't find the native libraries and it
can't find the JDBC libraries in the CLASSPATH. Otherwise, it can serve up HTML
pages at the correct port number so I know it's running.
When starting a managed server remotely via the WLS 6.1 console, how do I tell
the managed server where the native libraries and JDBC libraries are?
Thanks!

Hi,
The memory setting on the WC_Spaces managed servers can be seen as mentioned below.
ps -eaf | grep Spaces
Above command shows something like this at the top of the output:

How do specify Class-Path in exploded directory deployment?

Currently I have an app.ear(ejb.jar,lib.jar,web.war). In the MANIFEST file of
ejb.jar I do Class-Path: lib.jar. Now I exploded the app.ear and the components
into app(ejb,lib,web) directory structure, how do I write Class-Path? ../lib did
not seem to work for me. Any suggestions?

I got the answer at the EJb newsgroup. Instead of ../lib, use just lib.

How to use class path library

We are using java in built library to write the xml filw which "XSLT". One library named "saxon9he.jar" is already on my system at the path "C:\Program Files\Java\jre1.5.0_15\lib\ext" . when I run the progaram to read/ write in xml file, my progarm use this system library saxon9he.jar.
And generate the exception "Exception Caught while Checking tag in XMLjava.net.URISyntaxException: Illegal character in path at index 2: ./\config\SDBExplorer.xml stacktrace net.sf.saxon.trans.XPathException: java.net.URISyntaxException: Illegal character in path at index 2: ./\config\SDBExplorer.xml"
What I should do so that in class path it will take XSLT for xml operation instead of saxon9he.jar
Thanks!

The answer is to
- Remove the saxon9he.jar from the ${java.home}/lib/ext
- Add APIs to whatever application requires them, at run-time.

Servlet can't be found outside of weblogic/classes??

Hi there!
          I wrote a servlet that I've placed into a directory that's in my CLASSPATH
          (set inside startWebLogic.bat). It's clearly identified within the System
          java.class.path variable as well (when the logs scroll by).
          However, the Servlet (although it's been registered in Weblogic.properties)
          refuses to be found unless I finally move it into weblogic/classes.
          Does anybody know why??
          -joe


Joe,
          Servlets are loaded by the weblogic class loader. For that reason, the
          base directory for your servlets has to be in the weblogic.class.path.
          Since weblogic/classes is part of this class path, they were found by
          the WL class loader. Basically, add the base dir for your servlet
          package to the WL class path and you will be fine.
          If you're starting WL from the command line, see the
          /weblogic/startweblogic.??? scripts.

Class Path, Set Path

Imm new to Java Techology...plz tell me in detail bout how to "Set Class path", ....In Detail...Bye

To set class path
we type
set classpath= c:\j2sdk folder\lib;.;
set path = c:\j2sdk folder\bin;.;
setting these both will work out. in this .; ending means the class path will be available throught otu the command prompt where ever which ever folder it is..
well for setting permanent in the system for win2000 OS
right click on myComputer icon there from that option you select properties
then you get a pop up window where you have few tabs in which last one is advanced -- click on it
then you get there button placed vertically .... in which there is button callled Environment variables
click on it... you will get an window...
in that see the user variables box
In this if there is a variable to see as classpath then append the path of j2sdk folder\lib;.;
if not present then create a variable and set the name to classpath and value to the pathof folder\bin;
similalry path in that also if exist then edit it and give path to bin folder of j2sdk folder..
this will work out for you..

How to run a jar file which needs another jar to be in the class path

Hi,
I need to execute a jar, which needs another jar to be in the classpath.
If I run like
java -classpath <jar1 name> -jar <main jar>
It is giving classnotfoundexception, where as the class is available in the <jar1 name>.
so, currently I am doing like this
In the manifest file i have given like
Main-Class: <class name>
Class-Path: <jar name> <jar name2>
then it is running fine. But, if I want to change the jar location again I need to changed the manifest file.
Is there any way to do this? Pls help me.

How about
java -cp jar1.jar;jar2.jar com.acme.MainClass
You won't need to worry about the manifest file after that and you can make a bat files (or .sh file in *nix) for it.
