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

  • How to set the CLASSPATH in Unix Server

    Hi, everyone~
    Do anyone noe how to set the CLASSPATH in the hp-ux server? I tried the setenv CLASSPATH, but not working.. I think should use export. But my jsp pages still cannot working, dunnoe y?
    I wonder is the hp-ux support jsp and servlet or not?
    In order to let the jsp and servlet to run properly in the unix server, what kinds of steps should taken ?
    Hope somemore who experience with this situation b4 can give me some guidance.. Thanks~~

    Tomcat ignores any and all CLASSPATH environment variables. Even if you could figure out how to set it, Tomcat wouldn't use it.

  • How to set the classpath and path from the jsp to call  java class function

    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.
    Thanks,

  • 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).

  • 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.

  • 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!

  • 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.

  • 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?

  • Setting the classpath

    doing a jsp page which calls for:
    <%@ page import="java.sql.*" %>
    <%@ page import="javax.sql.*" %>
    <%@ page import="sun.jdbc.rowset.*" %>
    <%@ page import="java.util.*;" %>
    at the top of the page , so i downloaded the jar files that i needed and set the classpath to:
    C:\jdk1.3.1_01\rowset.jar;C:\jdk1.3.1_01\jdbc2_0-stdext.jar;C:\jdk1.3.1_01\jndi
    this is the first time ive set the classpath
    but when i run the page i get loads of Error: Could not find package named:
    anyone no what im doing wrong?

    When you say you "set the classpath", does that mean that you changed the system CLASSPATH environment variable, or that you went into the configuration of whatever it is that's running your JSPs and put those jars and directories into the appropriate place?

  • Setting the CLASSPATH from the JVM by a class

    Hy experts
    I have an application thats searching a jar file and have to access classes from this jar file.
    There are two ways to do this:
    1.
    Loading the jar file byte by byte and create the classes to load them into memory. This is the hard way.
    2.
    Setting the CLASSPATH variable in the running program! Thats the easy way! May how does it works?
    Is there any possiblity to set the classpath in a running application or only in the shell?
    Thanks for help
    konrad

    the classpath is readin when you run the JVM ie issue the 'java' command, the environment cant be altered to update a new classpath. However, why not just put the files you wish to load at runtime within the current classpath you've setup. If you use the System.loadLibrary(), you should be able to pick up the classes you wish to readin at run time via this approach.
    good luck
