Thread: 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 :

Hey ! I have solved my Problem on compilation time error.Now I am getting something different errors.
C-EJB-Demo and ppt.In demo StatelessBean.In StatelessBean classes ,META-INF and src.
In classes examples(After compilation making .class file).In META-INF no folder.

C:\EJB\Demo\StatelessBean>javac -d.\Classes C:\EJB\Demo\StatelessBean\src\*.java
When I used the above command on command prompt then got the following Errors :

javac: invalid flag: -d.\Classes

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 :
