    Make sure that you have set the classpath of the server. In other words, make sure that your server's batch file is not changing the classpath that you set on the console.

    Have you done the import of the bean?

    <%@ page import="packages.BeanName"%>

    You should put a line like that on the top of the page.

    Maybe this will help you.

  6. problem in weblogic(jsp calling bean)[ Go to top ]

    Hi,

    U donn't need to import the beans..

    U put u'r bean in a package, say com.bean.test.TestBean
    and put the class file in the WEB-INF/classes/com/bean/test
    folder and in the jsp u mention the full path fo the bean class
    <jsp:useBean id="test" scope="session" class="com.bean.test.TestBean" />

    Hope this helps

  8. problem in weblogic(jsp calling bean)[ Go to top ]

    Hi,

    Sorry.. i gave the path for weblogic6.0.

    For 5.1.. i guess u have to put the javabean class files
    weblogic/myserver/serverclasses.
    for examples if u'r beans r in package com.bean.test
    then put u'r bean class files in
    weblogic/myserver/serverclasses/com/bean/test/TestBean.

    jsp will be the same as i told before..

    I think u no need to put it in clientclasses

    Try it out and let me know..

  10. problem in weblogic(jsp calling bean)[ Go to top ]

    Hi,

    The problem will be in u'r environment settings..
    serverclasses may not be included in the settings..
    If possible send u'r env settings in u'r system..
    Check u'r setEnv batch file in weblogic folder..
    And how did u declared u'r bean initialisation in the jsp..?
    If i get these inf i try to solve u'r prob...

  11. problem in weblogic(jsp calling bean)[ Go to top ]

    hai saran,
     yes definetely there is a problem in classpath...i didnt modify anything in startweblogic.cmd or setEnv..i just use a batch file..i execute it before starting the server..i have given it here

    set path=%path%;e:\weblogic\bin\oci815_8;e:\weblogic\oci\bin\oci815_8;
    set classpath=%classpath%;e:\weblogic\lib\weblogic510sp8boot.jar;c:\jdk1.1.8\lib\classes.zip;e:\weblogic\classes\boot;e:\weblogic\eval\cloudscape\lib\cloudscape.jar;e:\weblogic\lib\weblogicaux.jar;e:\weblogic\classes;e:\weblogic;e:\weblogic\myserver\clientclasses;
    set Dweblogic.class.path=%Dweblogic.class.path%;e:\weblogic\lib\weblogic510sp8.jar;e:\weblogic\classes;e:\weblogic\licence;e:\weblogic\lib\weblogic\weblogicaux.jar;e:\weblogic\myserver\serverclasses weblogic.server


    i think i made a mistake here..pls tell me what is wrong in the above file..if everything is right then tell me am i have to modify anything in the startweblogic.cmd or setenv

    pls clear this

    thx a lot

  12. problem in weblogic(jsp calling bean)[ Go to top ]

    Hi,

    Try with including the serverclasses in u'r CLASSPATH environment variable though its there in weblogic classpath.

    U'r CLASSPATH should be as:

    CLASSPATH=
    %CLASSPATH%; e:\weblogic\lib\weblogic510sp8boot.jar;
    c:\jdk1.1.8\lib\classes.zip; e:\weblogic\classes\boot; e:\weblogic\eval\cloudscape\lib\cloudscape.jar; e:\weblogic\lib\weblogicaux.jar;e:\weblogic\classes; e:\weblogic;e:\weblogic\myserver\clientclasses;
    e:\weblogic\myserver\serverclasses

    I guess all other path settings r correct.

  15. problem in weblogic(jsp calling bean)[ Go to top ]

    Hi guys,

    It's quite interesting to see your conversation. As per my knowledge whatever the path saran mentioned should work.

    ELSE

    Try this:

    inside jsp:

    <page import="xxx.yyy.BeanName">
    <jsp:useBean id="xxxxx" scope="yyy" class="BeanName">

    Location of JSP:

    Keep this JSP inside

    C:\weblogic\myserver\public_html (if u want create your own package and add in your property file)

    Location of Bean:

    C:\weblogic\src\xxx\yyy


    After doing this...

    Give the classpath of the bean in the post classpath of the startweblogic.cmd file:

    The classpath is:

    C:\weblogic\src\xxx.yyy

    after doing this start the server and call the JSP

    Hope this should work:

    if u have further problem give a msg
    regards
    Moorthi
