i am using following commands at dos prompt:
mkdir build build\META-INF
copy *.xml build\META-INF
javac -d build Account.java AccountHome.java ProcessingErrorException.java AccountBean.java
cd build
jar cv0f Account.jar META-INF mydomain
cd ..
java -classpath %WL_HOME%/lib/weblogic_sp.jar;%WL_HOME%/lib/weblogic.jar weblogic.ejbc -compiler javac build\Account.jar %APPLICATIONS%\Account.jar
