    Angry EJB COMPILATION ERROR(TANMAY SINHA)

    I have installed on my machine weblogic 8.1 SP3.I am using jdk 1.7 version on my machine window xp.I have written my EJB Source code on my macine in
    D drive by using Advance_Java folder,in Advance_Java folder created EJB folder,in EJB folder created Demo folder,in Demo folder created Stateless
    folder,in Stateless folder i created classes,META-INF,src folder and I written

    set path=c:\bea\jdk142_04\bin;
    set classpath=c:\bea\jdk142_04\lib\tools.jar;c:\bea\we blogic81\server\lib\weblogic.jar;.;

    these above set path and set classpath in notepad and saved it with SetPath.bat extension.This SetPath created in Stateless folder with Classes,
    META-INF,src folder.In src folder I have written 4 source codes Hello,HelloBean,HelloClient,HelloHome in notepad with .java extension.

    In classes folder i created examples and META-INF folder.



    I am showing my Program compilation details are given below,so you look and read it carefully and solve my problem :

    C:\EJB\Demo\StatelessBean>javac -d ./classes C:\EJB\Demo\StatelessBean\src\*.java
    This command is correct command for compile the program(Source code).After writing the above command I compiled the Programs without any Errors.I got the class file after compilation in appropriate folder location.Yes when I put a space after -d then solved my problem.

    But you find this errors thats I am showing below :
