Comparing .java files in JBuilder

Is this possible? I couldn't find this discussed elsewhere on the forum and am curious if and how this can be done. Currently using JBuilder 3.00.
The problem is that I have two slightly different .java files (applets) where one works and one doesn't. I'd like to have it step through both files and tell me where the differences are (like diff in unix--and no, I don't have a unix platform available to just use that :p ).

I'm not aware of that feature directly, but it's been awhile since I used JBuilder. Why don't you post to some borland newsgroup and see if any one knows the answer? Most IDEs have some limited version history that will allow you to compare versions of the same file. You could make one copy of the file your first version and the separate copy the second version and then compare ... ... ideally, you'd use a source control application for finding the differences.

JBuilder question on how to add a new .java file

I am new to Java and even newer to JBuilder. I am creating the GUI for our school project and my other members are creating the networking and database parts of our program seperatly. I am at the point were I need to import their .java files into my project I created in JBuilder.
Can someone tell me the steps I need to take to get those files into my project so I can start using the classes from my group they made up?
Thanks,
Scott

You can use show_alert statement and then make a check on button that is pressed from the alert.
Here is an example of show_alert built_in.
DECLARE
my_alert number;
ALERT_TXT     VARCHAR2(200) := 'Do you want to delete record?';
BEGIN
     set_alert_property('your_alert',ALERT_MESSAGE_TEXT,ALERT_TXT);
     my_alert := show_alert('your_alert');
     If my_alert = Alert_Button1 Then
         /** I choose to delete record **/
        -- here you can put your statements
       else
       -- I pressed NO button
       -- here you can put your statements
       end if;
END;Hope it helps you,

How to open acrobat in java and compare two files using javacode

I am absolutely new to use acrobat software in Java. I want to open two pdf files at a time and then compare the differences between them thru java program .
i am not sure how to do it. iam trying many ways without success.
I used jre and could open open files using runtime method , but couldn't do comaparision. i..e could't access tools menu (alt+t) Compare two files and <enter>. help in java will be appreciated.
Pls guide me the steps to use the acrobat library. At http://partners.adobe.com/asn/acrobat i found supporting vb and vc only.
Any help or links are greatly appreciated.

iText is an open source PDF library, reads a PDF one page at a time. You could check it out. I've used it for writing/splitting/concatenating PDFs, but not comparing files

Tools for Comparing Java Class Files

Are there any tools out there that can compare two .class files to see if they are the same ?? Please help.
Janet

In Windows there's the FC command that compares two files to see if they are identical. In Unix there is no doubt a similar command. Or you could write a small bit of Java code that reads the two class files and compares them byte by byte.

Error while compiling java file using J2SE 1.5.0

Dear Sir,
I'm getting the following error while compiling the java file.The code is also given.
package test;
public class TestRowSet {
public TestRowSet() {
"TestRowSet.java": cannot access java.lang.Object,bad class file: D:\Program Files\Java\jdk1.5.0\jre\lib\rt.jar\java\lang\Object.class,class file has wrong version 49.0, should be 48.0,Please remove or make sure it appears in the correct subdirectory of the classpath. at line 4, column 1
Please help me out.
--Suketu Naik.

But I'm compiling within "Borland JBuilder 9.0". I've
set the JDK path of the current project to point to
the path of JDK 1.5.0 . I've also tried to compile at
command prompt with "javac". I'm getting the same
error of "Undefinedclassloader" with long StatckTrace.
I don't know anything about JBuilder either. If you use the command prompt and enter the full path to the 1.5 javac.exe then that will prove whether the issue is using an older javac or not. For example "c:\j2sdk1.5.0_01\bin\javac HelloWorld.java"

Cannot import self-defined .java files?

Hi,
I created a MouseHandler.java file that contains a class (without main() ). and I have another appletcode.java file that needs to import it:
import MouseHandler;
I tried to javac appletcode.java and it said it couldn't find the package MouseHandler but I didn't package it in the first place.
I tried JBuilder to compile it and it too gave:
"Class required but identifier found at line 1, column 1"
How do I import my source file(if it is possible)?
Thanks.

As it stands, if the compiled .class file is in the
same directory as your program, it should run fine
without the import statement. Notice, the import is
failing, but your references to it aren't?It's in the same directory. I took out the import statement and it gave error:
class MouseHandler not found in class appletcode at line ..., column ..
PS: this code is actually from Beginning Java 2 by Wrox. Since mine couldn't work, I downloaded their code. Their code didn't contain the import statement (which should work like you said), but when I compile their code, it gave the same error as above too.
Assuming that code and directory is correct, is there any other possible reasons why this is happening?
Thank you

Replacing Class definition comments in java files.

Hi to all,
Im trying to implement a java file replacer that opens about a thousand java files and replaces the first comment lines. That is to say assume that these thousand java files have this comment at the beginning of them:
*Date Author Changes
*${date} ${author} initial release
My application should find these comments and replace them with
* Project Name:
* File: ${file_name}
* Purpose:
* History:
*Date Author Changes
*${date} ${author} initial release
I dont need any GUI. just I will print the changed files to console.
My question is is there any example applications you guys can suggest and should I use XML and XSL to implement this application?
Any suggestions are highly appriciated.
Best Regards.
Metan

How is XML going to help you? Also for a task which you describe its easier to replace it wholesale rather than compare what is present and what is not. If you want to selectively want to remove stuff you might run into issues where you have to compare the name of the file, and you would not even know if the documentation already existing is the right one if you do not replace.
If at all you wish to go with XML it is better with XSL transforms but I guess that would be an overkill for the purpose.
As previously suggested perl is a very good option, or if you have unix operating system you can even try some basic shell scripting to do your job
Thanks

How to mention a Relative path in a java file

How to mention the relative path of the file in fileinputstream?
The directory structure is as follows,Inside the **model** folder i have a java file called GetContents.java
I need to refer the input.xls file inside the template folder in GetContents.java.file.
I tried new FileInputStream("..\\..\\..\\template\\DevContentsTemplate.xls") cos the GetContents.class file will be inside webcontent\web-inf\classes\model\GetContents.class and I thought if i use the above relative path , it should refer webcontent\web-inf\template\input.xls
But it throws a file not found exception.

if so then for one ../ you will reach classes folder. for another you will reach the folder containing src, classes, templates etc.
So you do not need 3 escapes.I posted that same answer 7 hours before you did! What part of your answer is any additional help compared to mine? It's fine to give someone another answer, but there's not much point in giving the SAME answer 7 hours later. If it were a few seconds or a few minutes later, I would excuse you for having tried to post at the same time. But, 7 hours?! Please read the existing answers next time, not just the original post.

Need Sorter java file   for sorting the records in webdynpro java

Hi Gurus
   I had urgent requirement please give your inputs
   In my webdynpro java i need to sort entire records in table
   I now we need One sorter java class please provide that java file
   please suggest the all the steps how to do
Thanks
renu.

1. Implement class comparator wich will compare records according your sort preferencies,
like this:
     public class record_Comparator implements Comparator{
          public int compare(Object emp1, Object emp2){
      // here is your code for return -1if 'before' or 0 if equal or 1if 'after'
               int stepId_1 = ((record)emp1).get_someValue();
               int stepId_2 = ((record)emp2).get_someValue();
               if(stepId_1 > stepId_2)
                    return 1;
               else if(stepId_1 < stepId_2)
                    return -1;
               else
                    return 0;
than call method sort() with your collection of records,
like this:
Collections.sort(record_collection, new record_Comparator());

How to compare the files from one server to another

Hi !
I want to compare the files present in one server to another server. I had to list out the files which is not present in the server and import those files to an excel file. There are lot of folders and lot of files present inside those folders. I want a java or jsp or javascript program code for this or any site which indicates how to do. What are the requirement for this program to implement like any tool or any other techniques. Please can u help me out.

No ... The package mentioned in
http://www.oracle-base.com/dba/miscellaneous/ftp.pks
this works for across the server i.e. transfer the files from one server to other (it is basically ftp) ..
So it is NOT correct that this code transfer the file between two location & with in server..

If you have two public class in a java file what will be the error ?

Q:If you have two public class in a java file what will be the error and how will you remove that.?

Kannan_S wrote:
I dont want you to be on that list . Here goes my explanation..
A class is well defined with members and functions
An abstract class is not defined well as compared to a full fledged class (talking more generically)
An interface is more abstract.
I was asking the author who has posted this question to be like a class(very clear)
and not either as an abstract class or an interface
Hope i have made it clear..Not in the slightest. This has absolutely no bearing whatsoever on the question asked. Not to mention that classes are classes, and all equal in the eyes of the compiler, be they abstract, concrete or interfaces. It's difficult to see what your point is, to be honest, but I suspect it wouldn't be worth seeing anyway

Run java class using JBuilder

hi,
I already import the java class forder to the src folder in JBuilder where the src folder is created by the JBuilder itself. When i run compile the program there is an error in reading the java class file but when i run the program in Textpad, the program is success. May i know why? how can i run my program using java class in JBuilder instead of Java source? Thanks.

In JBuilder there is an option of specifying what the 'main' file in a project is . Specify that to this class file
[ What I mean is , in many java files we can define 'main' method , but we will intend to execute the main of one file only for a project . In JBuilder specify this file as the main class file ]
