Hi Vibhor, Please refer to examples directory of weblogic 5.1.Copy one ejb-jar.xml,weblogic-jar.xml files to your directory.Change the same as per your requirement. Following is the ejb-jar.xml for a stateless session bean <?xml version="1.0"?> < !DOCTYPE ejb-jar PUBLIC '-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 1.1//EN' 'http://java.sun.com/j2ee/dtds/ejb-jar_1_1.dtd'> <ejb-jar> <small-icon>images/green-cube.gif</small-icon> <enterprise-beans> <session> <small-icon>images/orange-cube.gif</small-icon> <ejb-name>statelessSession</ejb-name> <home>examples.ejb.basic.statelessSession.TraderHome</home> <remote>examples.ejb.basic.statelessSession.Trader</remote> <ejb-class>examples.ejb.basic.statelessSession.TraderBean</ejb-class> <session-type>Stateless</session-type> <transaction-type>Container</transaction-type> <env-entry> <env-entry-name>WEBL</env-entry-name> <env-entry-type>java.lang.Double </env-entry-type> <env-entry-value>10.0</env-entry-value> </env-entry> <env-entry> <env-entry-name>INTL</env-entry-name> <env-entry-type>java.lang.Double </env-entry-type> <env-entry-value>15.0</env-entry-value> </env-entry> <env-entry> <env-entry-name>tradeLimit</env-entry-name> <env-entry-type>java.lang.Integer </env-entry-type> <env-entry-value>500</env-entry-value> </env-entry> </session> </enterprise-beans> <assembly-descriptor> <container-transaction> <method> <ejb-name>statelessSession</ejb-name> <method-intf>Remote</method-intf> <method-name>*</method-name> </method> <trans-attribute>Required</trans-attribute> </container-transaction> </assembly-descriptor> </ejb-jar> Here's the weblogic-jar.xml
and here's the build file you have run after creating above files It's .cmd file @REM Copyright (c) 2000 BEA Systems, Inc. All Rights Reserved. @REM Adjust these variables to match your environment if "" == "%JAVA_HOME%" set JAVA_HOME=\java if "" == "%WL_HOME%" set WL_HOME=\weblogic set MYSERVER=%WL_HOME%\myserver set MYCLASSPATH=%JAVA_HOME%\lib\classes.zip;%WL_HOME%\classes;%WL_HOME%\lib\weblogicaux.jar;%MYSERVER%\clientclasses @REM Create the build directory, and copy the deployment descriptors into it mkdir build build\META-INF build\images copy *.xml build\META-INF copy *.gif build\images @REM Compile ejb classes into the build directory (jar preparation) javac -d build -classpath %MYCLASSPATH% Trader.java TraderHome.java TradeResult.java TraderBean.java @REM Make a standard ejb jar file, including XML deployment descriptors cd build jar cv0f std_ejb_basic_statelessSession.jar META-INF examples images cd .. @REM Run ejbc to create the deployable jar file java -classpath %MYCLASSPATH% -Dweblogic.home=%WL_HOME% weblogic.ejbc -compiler javac build\std_ejb_basic_statelessSession.jar %MYSERVER%\ejb_basic_statelessSession.jar @REM Compile ejb interfaces & client app into the clientclasses directory javac -d %MYSERVER%\clientclasses -classpath %MYCLASSPATH% Trader.java TraderHome.java TradeResult.java Client.java This is for the Trader Example.Please check your jdk path in the build.cmd file. I hope this will give you lot of inputs for further exploring the EJB.Wish you Happy Exploring EJB. Bye, Mahesh
