Setting classpath in WebLogic 7.0

I'm a WebLogic newbie.
I've developed some simple EJB and everything works fine.
I want to add an external package (jar file) to the classpath but
can't figure out how to do it.
Detailed help will be most welcome (which file to edit or directory to
throw your jar files in).

If your a newbie this sounds daunting I am sure.
But if your going to do do this easily and right, pick up a book on Ant, it will
easily build jar's with manifest classpaths.
This is much easier in 8.1 coming soon..... stay tuned.

Setting CLASSPATH question

Hi,
          I'm evaluating Weblogic 5.1. My evaluation requires me to write an
          Enterprise Java Bean that uses Container Managed Persistence, place it on a
          server, and have an HTML page call into the EJB through a servlet. The
          servlet is also sitting on the server. I've managed to prove that this
          works within the confines of Visual Cafe EE, but cannot make it work
          independantly.
          I've set my HTML page to have a link to the servlet I need to hit
          (http://Local IP:7001/ServletName). The EJB is properly deployed. The
          servlet is registered in weblogic.properties. But when I hit my link, it
          returns a "10.5.1.500 Internal Server Error". And the server throws a
          ServletException which tells me that "Servlet class:
          weblogic.servlet.ServletName could not be loaded - the requested class
          wasn't found in classpath."
          "weblogic.servlet.ServletName" is my location on the server. I've
          registered that location in my wl.props and it shows on the server. I'm
          running Win2K and have the location of my EJB and location of the servlet in
          both the User CLASSPATH and the System CLASSPATH.
          Can anyone help me out? Where can I find the exact meaning of error
          "10.5.1.500 Internal Server Error"?
          Feel free to contact me at [email protected] or directly at 303-987-3499

          I'm having a little trouble understanding "my location on the server". The
          registration is for associating names with classfiles. Thus, in order for
          what it seems like you're saying here to work, you'd need (assuming a
          default installation of WLS):
          in weblogic.properties:
          weblogic.httpd.servlet.classpath=c:/weblogic/myserver/servletclasses
          weblogic.httpd.register.ServletName=weblogic.servlet.ServletName
          on the filesystem:
          c:\weblogic\myserver\servletclasses\weblogic\servlet\ServletName.class
          >
          >Can anyone help me out? Where can I find the exact meaning of error
          >"10.5.1.500 Internal Server Error"?
          From this error, I can determine that you do have the register part of the
          properties file properly set up. Either the class file is not there (see
          filesystem statement) or it does not have the proper package statement.
          The error is actually "500 Internal Server Error". The 10.5.1 might be a
          documentation reference (Cameron? BEA?), but the 500 error is sufficient.
          It means the web server you're talking to had a processing error that it
          couldn't recover from and thus could not return the response you requested.
          You'll usually get in in servlet failures, or app server failures.

Setting CLASSPATH's on Windows & Linux

I am still new Java programming language, but I am coming along in learning the actually language. The one problem I keep running into is how to set a CLASSPATH on a windows machine and Linux machine. I have currently installed j2sdk1.4.2 on the windows machine and jdk1.5.0 on the linux machine. If any one has any suggestions on how to set these CLASSPATH's I would greatly appreicate it.

Before ammending classpath I recommend checking the
windows path variable. This variable is a list of
folders where windows looks for executables.
Path can be viewed by going to control panel ->
system _> advanced table -> environmental variables
and then selecting path and then edit.
Make sure �C:\Program Files\Java\J2SDK1.5.0\bin� (or
equivalent)is included.
Alternative you can enter �path = %path%; �C:\Program
Files\Java\J2SDK1.5.0\bin� into command prompt each
session.
This ensures that you can compile and execute java
programs from any directory. Ideally the java
installer should do it but I have found it does not.Indeed.
Similarly the classpath can be varied from either the
command prompt or it can be added to the
environmental variables.I'm one of those that recommends folks not set CLASSPATH using an environment variable.
IDEs like Eclipse and IntelliJ totally ignore it; so do containers like WebLogic and Tomcat.
One CLASSPATH does not fit all. Every project is unique. The best way to set it is with the -classpath option on both javac.exe and java.exe.
For compiling, you should learn Ant. It's a make tool built on Java and XML. That'll help with your compilation issues.
For running, you'll either run in a container, which has its own idea of CLASSPATH, or you can script the startup of a batch job using a Windows .cmd or *nix .sh. Set the CLASSPATH in the script.
If altering it from the command prompt, in windows
use a �;� between paths variables and a �:� for unix
systems. Also include a �.� as one of the path
variable as it includes the pre-existing class path.
For example, when entered from the command prompt (in
windows), the following line will add �C:\
JavaPrograms� to the existing Classpath
Java �cp .;C:\JavaPrograms
Alternatively go into environmental variables as
described above and if a classpath variable does not
exist, create one and include �.� and your desired
directory.
Note: I prefer adding directories to the classpath
via the environment variables as it is more accepting
a folders with spaces in the name.Installing software in a folder with spaces in its name is asking for trouble. It's not highly recommended.

Trouble Setting Classpath on Windows XP

I'm having trouble setting up a classpath on Windows XP for SDK1.3.1_04.
I've tried Control Panel\Advanced\Environment Variables\System Variables. There was a Path variable present, to which I've added:
c:\jdk1.3.1_04\bin;
There wasn't a Classpath variable present though. I've tried adding it myself in System Variables as follows:
Variable name: Classpath
Variable value: set classpath=.;
But no joy. When I run "set" from the command prompt, there's no classpath present.
I'd appreciate any help.
Cheers.

Hi,
I am running on XP (unfortunately), but also win2000 and win98.
Setting up the classpath is not a problem, although if you are logged in as root, then it does not always show correctly.
Try logging back in as yourself and then checking the classpah through the set command.
Altrnatively, if this is not the problem, actualy try a reboot. which should not be necessary.

How to set classpath from java class ??

I have tried to use System.setProperty("java.class.path", "my class path string ") to set classpath dynamically. But it is not working. How to set it dynamically from java class ?? Thanks , gary

Look into the java.net.URLClassLoader. You can't set the classpath after the fact but you can specify URL's that will checked when you try to load a class with that loader.

Don't worry about it. The CLASSPATH variable is best avoided anyway. Specify classpaths for particular apps on the command-line. Teh Docs show you how

Please help.This suggests you're talking about PATH rather than classpath. Do you understand the difference?

Setting Classpath in linux

Hi !! Can anyone help me in setting classpath in linux to run servlets/? I tried using this command..but didnt work
export CLASSPATH="$CLASSPATH:/usr/share/tomcat5/server/lib/servlets-common.jar"
Thanks
Nive

in ur autoexec.bat file write the following
set PATH=C:\jdk1.5.0_04\bin;%PATH%
set JAVA_HOME=C:\jdk1.5.0_04
set
CLASSPATH=.;C:\jakarta-tomcat-5.5.9\common\lib\servlet
-api.jar;C:\jakarta-tomcat-5.5.9\common\lib\jsp-api.ja
r;C:\Servlets+JSP;..;..\..;C:\jakarta-struts-1.2.4\lib
\struts.jarThis response is meaningless. Principally because the OP specifically mentioned the use of LINUX. Not Windows.
I've taken the advice of other forum users by avoiding a system level classpath variable. I define the classpath each time I compile and run. Working on Linux I tend to use command line argument files ( http://java.sun.com/j2se/1.5.0/docs/tooldocs/solaris/javac.html#commandlineargfile ) which eliminates the need to redefine the classpath each time I compile or run my classes and apps. But others may do things differently.
Here is a website you might want to check out which pertains to setting the classpath on Solaris and Linux.

It does not either if set classpath= blabla\WEB-INF\classes\myjar.jar

Help with setting classpath

Hi All,
I am new to servlets and JSP. I have a question regarding setting Classpath. My development directory structure is like this c:\..\desktop\java\project1\src\com\eg\web\e1.java. Servlet.jar file is in C:\Program Files\Apache Group\Tomcat 4.1\common\lib. I tried setting Classpath in windows 2000 using control panel=>System utility by this command
SET CLASSPATH=.;c:\Program Files\Apache Group\Tomcat 4.1\common\lib\servlet.jar . I try to compile my program by going into the whole development directory structure C:\..\src\com\eg\web using javac e1.java. But I get the error "package javax.servlet does not exist". Can somebody help me resolve this?
Thank You in advance

Question 1: Are you using an IDE?
[IDEs ignore the system classpath]
Question 2: Did you try setting the classpath using the -cp option for javac, if you are not using an IDE?
[you could also try to print the classpath on command line to check if it has taken effect]

Setting Classpath on windows platform

Hello
I was trying to set classpath of "D:\documentum\config" in my environment variable , i was doing it through command
prompt , the command i was implementing was
set classpath=D:\documentum\config;
but the when i was closing command prompt , the environment variable in windows named as ClassPath was not updating
i have also tried this command
set classpath=%classpath%;D:\documentum\config;
this also having the same result , so how can i set this property through command prompt
Regards

You can permanently set command line environmental variables through the advanced settings in Windows. You have to hunt around for it a bit, it is somewhere behind opening the right click properties of "my computer" (or whatever it is called in your flavor of Windows) and then choosing advanced. An "environmental variables" tab should be present there.
BUT! I would not advise you to set a classpath variable unless you fully realize that is only to make your development life a bit easier when working on the command prompt. When making your application ready for deployment the classpath must be managed without the variable. A script could work, or packaging everything up as an executable jar. When you start to work with an IDE like Eclipse or Netbeans you don't need that variable at all any more.

Setting classpath from the command prompt

each time i try to set the classpath from the command prompt it is not always well done . can someone give a good format
i.e set classpath = ;c:\document and settings\ luke

Anyway, try:
set classpath = ".;c:\document and settings\luke"

In UNIX how to set classpath

I know nothing about UNIX. pls kindly give me some instruction on how to set classpath in UNIX, thanks!

best way is to set in your .profile (name differs between different shells, but whatever the OS/Shell is, it should starts with . and has a 'profile' string in the name). Try ls -a to find the file, edit it, insert lines like this:
CLASSPATH=xxxx
export CLASSPATH
Use : to seperate different path/files.
then every time when you log in, the classpath is setted.
if you already logged in, use the above lines in command line, but it only set class path of the current shell/console.
anyway, you should learn Unix before you do anything, or you'll have more trouble. do a search in yahoo or google to find on line tuturials, and SUN's Java tuturial has some basic instructions on how to use Java in Unix.

Set classpath in Window 95, 98, ME

Hi,
Would anybody please show me how to set the class path in windows 95, 98, ME.
I used: set classpath=c:\ but it did not work
Thanks

hi,
Instead of using 'classpath' try and use just 'path'.
If JDK is installed in C: then the path would be
"path=c:\jdk1.3\bin;%path%"
