Does weblogic.Deployer set the CLASSPATH?

Hi,
I need to deploy an application with the weblogicDeployer utility. Does it automatically
set the CLASSPATH, as is done with the Admin console? Or do I need to set the
CLASSPATH explicitly?
Thanks,
-Ami

ah. weblogic.Deployer and the console use the same underlying API to
our Deployment subsystem. There shouldn't be any difference in
application behavior (eg classpath).

Novice Trying to Set The CLASSPATH Variable

I am trying to compile a file (which can be downloaded at http://java.sun.com/docs/books/tutorial/getStarted/QandE/FirstClass.java). Despite being able to successfully compile several other files, this particular one will not compile. According to my JAVA Tutorial book, the problem may lie in the CLASSPATH variable, but I am having a great deal of trouble trying to set/understand it. My operating system is WINDOWS 2000. PLEASE HELP!!!

in win 2000, the classpath can be set by the following process.
Right Click My Computer icon and click on properties.
(This can be done by going to the Control Panel and Double Clicking the System icon too).
Once you have the properties window of the system click on the 'Advanced' tab.
There is a button called 'Environment variables'.Click on it.
You will have a part called 'System Variables' there.
Here there is an entry called Classpath. Just add the entry of what you want to add to the classpath, separating each entry with a ';' semicolon as mentioned there and click on the Set button.
That should set the classpath.If that does not take effect immediately, restart the system and it will take effect.
Tell me if it worx.
All the best. Bye!
Cheers,
Win!

I can't set my classpath to compile serlets any help?

I don't understand I'm doing it the way my book says to do it but I can't for the life of me set a freaking class path for my tomcat server so I can compile my serlets here's how it says to do it
C:\Documents and Settings\Compaq_Owner\Desktop>javac -classpath C:\Program Files\Apache Software Foundation\Tomca
t 5.0\common\lib\servlet-api.jar
Can anyone tell me what the hell I'm doing wrong any help is greatly appreciated thanks

Ok I think I get what your saying but couls someone show me the syntax where to include the source files at and how here's what I did but it couldn't read the file so I'm guessing I'm not putting it in right and also is there a way to permanently set the classpath so I won't have to go through this everytime I want to compile java servlet files?
C:\Documents and Settings\Compaq_Owner\Desktop>javac -classpath "C:\Program Files\Apache Software Foundation\Tomc
at 5.0\common\lib\servlet-api.jar" "C:\Program Files\Apache Software Foundation\Tomcat 5.0\webapps\jhtp6\WEB-INF\
classes\WlcomeServlet.java"
error: cannot read: C:\Program Files\Apache Software Foundation\Tomcat 5.0\webapps\jhtp6\WEB-INF\classes\WlcomeSe

Java newbie questions...Setting the classpath in Unix

When you set the classpath, how do you include anything already in the classpath? For instance, if your profile sets your classpath to
"/home/weblogic/:home/weblogic/weblogic.jar, and you want to add MyJar.jar to it, can you enter:
export classpath=~:MyJar.jar
My question really boils down to how do you prefix the existing CLASSPATH environment variable to any new classes or jars you want to add to it. I think it's the tilde, but I'm not sure.

In csh, the CLASSPATH environment variable is modified with the setenv command. The format is:
setenv CLASSPATH path1:path2
In sh, the CLASSPATH environment variable can be modified with these commands:
CLASSPATH = path1:path2:...
export CLASSPATH
====
(From the Sun documentation)
or, in sh,
export CLASSPATH=path1:path2
should work

T o set the classpath

my forlder is :C:\Documents and Settings\india
jdk is in:C:\Program Files\Java\jdk1.5.0_11\bin
can any body can help me to create a classpath for my folder

set classpath=C:\Program Files\Java\jdk1.5.0_11\binDon't do this.
The term "classpath" is used in two senses: it can mean the folders where user classes are located, and it can refer to an environment variable of the same name used for the same purpose. Since you won't be putting classes in he bin folder, and you will be putting them elsewhere, the setting posted makes no sense.
For a discussion of how classes are found and on setting the class path see the links at the top of this page: http://java.sun.com/javase/6/docs/technotes/tools/#general
I agree with the comment at the start of the start of the section on setting the classpath (http://java.sun.com/javase/6/docs/technotes/tools/windows/classpath.html), that it is better to specify the classpath by using the -classpath switch with the Java tools (java, javac, jar). In this case you don't use a classpath environment variable at all.
A typical HelloWorld is compiled and run with:javac -classpath . HelloWorld.java
java -classpath . HelloWorld

Help, how to install jvm and set the classpath using a batch file

hello,
i have created my java application and now have to create an installable / batch file which will install the JVM on the users machine and also the java packages such as javamail and the class files that i have created . it also has to set the classpath.
i would like to know if anyone can tell me how to go about iti.e. how can i install the JVM using a batch file and then place the javamial packages etc in the apropriate directory .
or is it advisable to explain it to the user how to go about it in tht user manual.
and would also like to know that if i install the JVM will the path for the java.exe be set
or will i have to set the path explicitly from the "batch file" so that the user can run the application without and problem just by running the java command followed by filename from the command prompt.

hi,
I have windows and I use it.
The only problem with the free edition is that you can only create 1 launcher and that during the installation you get 1 popup showing that the installer was created with an unregistered version.

Tomcat ignores any and all CLASSPATH environment variables. Even if you could figure out how to set it, Tomcat wouldn't use it.
Better to learn how Tomcat's CLASSPATH works and how to deploy Web apps properly. - MOD

Setting the classpath of classes12.zip for Tomcat

Hi
I am using Apache Tomcat webserver and while trying to run a jsp page which intializes oracle.jdbc.driver.OracleDriver it throws an error
java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver
Please suggest how to set the classpath of classes12.zip in Apache Tomcat
My Code Snippett
<%@ page import="java.util.*,java.sql.*,javax.servlet.*"%>
<body>
     <%
     Connection con ;
     ResultSet rs ;
     Statement stmt ;
     ResultSetMetaData rsmd ;
     try{
     Class.forName("oracle.jdbc.driver.OracleDriver");
     catch(Exception e)
     out.println(e);//print the exception on the command prompt
%>

The simplest way to do this is to copy classes12.zip to the WEB-INF/lib directory. The JSP should then find this automatically.
As a side note, that is an ancient JDBC driver - you might want to upgrade to something from this millennium.

It is never advisable to store large data sets in the session. But it will depend on a lot of factors:
1. How costly is the query retrieving the data from the database?
If it's a complex query with lots of joins and stuff, then it will be better to store it in the session as processing the query each time will take a lot of time and will decrease performance. On the other hand if the query is simple then it's advisable not to store it in the session, and fetch it each time.
2. Are there chances for the data to become stale within a session?
In this case storing the data is session will mean holding the stale data till the user session lasts which is not right.
3. How many data sets does the session already holds?
If there are large no. of data sets already present in the session, then it's strictly not advisable to store the data in the session.
4. Does the server employ some kind of caching mechanism?
Using session cache can definitely improve performance.
You will have to figure out, what is the best way analyzing all the factors and which would be best in the situation. As per my knowledge, session is the only place where session specific data can be stored.
Also, another thing, if the data set retrieved is some kind of data to be displayed in reports, then it would be better to use a pagination query, which will retrieve only the specific no. of rows at a time. A navigation provided in the UI will retrieve the next/previous data set to display.

I think it is Oracle 10g Release 2... since when I click the top OAS link in the Enterprise Manager Console, it took me to 'Enterprise Manager 10g Grid Control Release 2' this page.
And...10g Application Server Control Release 10.1.2.0.1, I think 2.0.1 means Release 2.
Thanks and let me know if you need something else.

How to set the classpath in CVM?

Hi everybody,
experimenting with the J2ME Personal Profile Runtime Environment on a Linux PC I wonder how to set the classpath. The command line options only allow me to set the bootclasspath.
My original problems deals with determining the codebase for a class that is contained in a jar.
1) If I put this jar into the bootclasspath, that class is found and can be loaded, but the codebase (retrieved using class.getProtectionDomain().getCodeSource) is NULL.
2) If I put it into the classpath by using the command line option -Djava.class.path=... the class cannot be found by the ClassLoader.
3) If I put the jar into both, the classpath and the bootclasspath, the latter one is applied and result 1) shows up.
Any idea how to work around this?
