One of the applications...

Suppose if you want to serialize an object which can be readable for an C++ program you can do it with externalizable. Assuming both entities understand the binary format.

Neither audience nor the question is dumb.. some times it also means that ppl. are busy Let me try to explain ..as far as I know.

To be frank, If you can understand the API doc of externalizable from JDK documentation, you are not a normal person .

Coming to the answer,

You must have noticed that Externalizable extends Serializable. Hence you can't put "VS" in between them. Externalizable is an enhancement over Serializable.

OK this is the theory behind Externalizable..

JVM has a mechanism to write or read an object from the I/O streams using its own representation (bytecode). This is done through readObject() and writeObject() APIs.

Assume if you want store the object in your own way, you must do with Externalizable.

It will look bit wiered, but thats how it is...

If you have Thinking in Java (Bruce Eckel), please refer it. The same example is available in this URL

Hope it helps.

Hi
I feel JExcel as best, it has lot of features when compared to others. no need to use driver manager, actually if you do so it will not give you a better performance as compared to others.

Hi, No need to compile JSPs just update them in web folder, just make a refresh in browser. the container will compile it.
If you want to precompile the JSPs it varies from container to container, WebSphere has a tool called "jspc" which will precompile jsp before deploying simlly, oracle also providet his facility in Oracle9i. but I dont think Tomcat has this facility if so pl. let me know how its to be done?

try out this,
request.getParametervalues("your checkbox name")
this will give you a string array of check box values that are selected. in your case 1,2,3, .... then do the processing based on the selected values.
