migrating JDK1.4 to JDK1.5

[karthik11]

Hi,

I am trying to make our application JDK 1.5 compatible. Currently we are using JDK1.4 which is working fine.

While building the ear file I am getting symbol not found error.

I am getting this error for the enterprise method. I am trying to invoke the stateless session beans using remote interface.

Kindly help me in fixing this issue.

Thanks,
Karthik

Each new version of Java is supposed to be backward compatible with previous versions. Occasionally there have been issues where things work slightly differently (or not at all) in newer versions but these are bugs rather than features changes. I've never heard of something that compiled in version 1.4 not compiling in version 1.5, can you explain exactly what you have done and also show the error messages you are getting and the relevant code.

My project structure looks like

Project
+ProjectEjb
+ProjectWeb

I am trying to invoke the ejb object in projectEjb from projectWeb using remoteinterface

LocalEJBServiceLocator locatorEJB = LocalEJBServiceLocator.getInstance();
FacadeHome facadeHome = (FacadeHome)locatorEJB.getRemoteHome("ejb/FacadeHome",FacadeHome.class);
Facade facade = FacadeHome.create();
facade.sendStatus(1);

[error]

[javac] C:\Inventory_Wrkspc\Project\ProjectWeb\JavaSource\com\bank\Web\SendStatusServlet.java:161: cannotfind symbol
[javac] symbol : method sendStatus(java.util.Calendar,java.util.Calendar)
[javac] location: interface com.bank.facade.ejb.Facade
[javac] status = facade.sendStatus(startDate, endDate);
[javac]

[/error]

[karthik11]

facade.sendStatus(startDate, endDate);

It looks like you are calling the method

sendStatus(java.util.Calendar,java.util.Calendar)

but this method isn't declared in the interface com.bank.facade.ejb.Facade

Are you sure your classpath is set correctly, javac may be picking up a different version of the Interface.
