signer information does not match signer information of other classes in the same package in Oracle forms java bean

• The Main issue to this ,is there are many jar File have same package name on it
• To Solve the issue ,used  JDeveloper or any java developer to combine Class from multiple jar into only one jar and sign  as example :-

clientinfos.jar has main pakge name is :-package

and javahost.jar has also smae page name 

combine this into one package  as follow using  JDeveloperVersion 11.1.1.2.0

1. Create new Project and give it any name 
2. Then  add all class from clientinfos.jar,javahost.jar using coy past 
3. After add both Class ,creat JAR profile and Sign it using wbutile sign script :-C:\Oracle\midtierhome\jdk\bin>C:\Oracle\midtierhome\forms\webutil\sign_webutil.bat C:\Oracle\midtierhome\forms\java\newjar.jar
