Yes completely rebuild.Removed class files and ran build.xml

I am deploying applications using Ant build.xml.
All is working fine when initially I use JRE1.4.I run build.xml by right clicking on build.xml and Runs>Ant build.These are my setting when it is working fine.
JRE Tab>Sperate JRE:jre1.4(One of Ant tabs)
I have to test my application in JRE5 also,I changed by Project setting to use Java5.Everything is fine,all worked.These are my setting when it is working fine.
JRE Tab>Sperate JRE:jre5(One of Ant tabs)
But now i came to back to jre1.4 for jre5,when try to access the applications I am getting unsupported version 49.That means all java classes are getting compiled in java5 and running in java1.4 as classpath is set like that.
Even though I have removed all the jre5 references I am still getting this error.Could anyone help me on this.

Hi All

My project requires to create multiple instances of Tomcat 5.0.25 on Windows XP machine
Instance1 should run JRE 1.4
Instance2 should run JRE5
Instance1 will have all the existing applications which are currently running on JRE1.4
Now we would slowly move to Instance2 where JRE5 is present and also all new applications will developed and deployed on Instance2.
Basically we going to use this method of creating Instance2 with JRE5 because we would like to move all the old applications to Java5.We have to go this way because of Java5 in compatability issues with Java1.4.
If we are able to create Instance2 with JRE5 we will slowly move existing applications from Instance1 with JRE1.4 after testing each application cartefully.

Please kindly help me on this if anybody has knowledge or implemented already in their respective projects.Please revert back to me with steps.

Thanks

What is Forward Referencing?

Can anybody throw some light UML Certification.
Who are offering and which is good at price and also the syllabus.

I know we can call just using Class name.
My doubt here is whether we can say both Instance Method and Static Method belongs to a class and not to Object

I would like to know what is the difference between Instance Method and Static Method?
I know that in Instance Method we can access the other instance members directly and in Static Method we access indirectly by using the Reference of an instance.I want to know which of these belong to a Class,becoz for variables we can say that static variables belong to class and instance variables belong to Object.

Garbage Collection happens on Heap Memory

Can anybody throw some light on this.

We all know String literals are allocated memory in Pool Interns.My doubt is how Java deallocates the memory after the usage of String literal.
