 Thanks,

Also if you're deploying a webApp, make sure to have a keepgenerated entry in the
 webapp deployment descriptor.
 It looks like the implicit variable exception is null the time you're making the
 call exception.getMessage. I would suggest to change this line to exception !=
 null ? exception.getMessage() : "whatever error message you see fit".
 Try this with all other variables you're accessing in the JSP.
 This way you can pinpoint the location where you're trying dereferencing null.
 If the implicit variable exception is the cause try the combination of <%page
 errorPage=...%> in the page causing the error and <%page isErrorPage="true"%>
 in page handling the error.
 Hope this helps.

Java File Missing while import

Hi,
When I try to import a project into the workspace, only one java file is missing(showing error : R3View does not exist).
Before I import the project, the folder contains that java file in gen_wdp folder. but after import, it doesnt. It automatically got deleted. I dint know how it happens. I have taken one copy of that java file. So I have created a new java file(R3View.java) in gen_wdp folder and copied the code. Now it works fine. I have taken this backup folder.
When I try to import it next time, the same problem exists. Actually the folder contains all the java files before import.
Why this problem occurs? Kindly help me out.
Regards,
Kalai

Hi,
As abhilash stated the folder gen_wdp always have generated code based upon web dynpro metadata.
You cann't contribute code by placing any souce file in this directory. That you have to do in some source directory that is generally "src\packages".
If you place code in gen_wdp folder and reload the project, do a dc build, or simple project build ....... the file will get deleted.

Java file missing in par file

Hi all,
We have a par file. After importing that par file in NWDS we could see only jsp pages. No Java file exists.
This par file is downloaded from our portal which is created by previous developer. I think previous developer did not selected "Include Source code" option while exporting par file to portal.
Now we need to changes in R/3 side and in java file. For that we need to know the Function Module or Report used in R/3. I think this data will be in java file.
Can anybody let me know how to find the java file related to a par file?
Regards,
Swapna.

Hi Bobby/n@v!n,
Thank you for the inputs given.
But I heard that we cant get the same java file (like original) when we use the Java Decompiler. We will get the file which gives the same output with different code. I'm not sure if we can the use the file given by java decompiler.
Is there any other way to get the original java file of given par file?
Regards,
Swapna.

I had java and bluej installed once befor but bluej went bonkers saying it couldnt find "system library" for system.out.println and when i tried to reinstall java came back with that message. so i reinstalled java.

Missing java file via eclipse.please help

There is a java file missing in my eclipse when i do an update
via svn.
the error class the class shows 'Trade cannot be resolved to a type
How do I import via SVN fo that specific file that is missing?
I tried doing a fresh update but still its missing?
please help

Suresh,
there are multiple ways to achieve that. If it is a "pure" java application create a java project.
If you put java files into portal, webservice etc projects, they be compiled with the projects build process.
To compile a single class you have also the option to configure an entry in the tool section (which points to javac for example) and run the tool, when your file is open (like in Visual Studio).

Checkstyle warning: Missing package-info.java file

Hi,
I'm getting a checkstyle warning for a simple class which looks like:
package tools.interprocess;
* Class for testing RMI.
* @author spinth
public final class RMITest {
     * Private constructor.
    private RMITest() {
     * Main method.
     * @param args User arguments
    public static void main(final String[] args) {
}The warning message says: Missing package-info.java file
I really couldn't figure out what this means and how I can fix it. Do I have to add something to the source tree?
I'm using Eclipse for development and Eclipse-cs as my checkstyle plug-in.
Thanks.
Edited by: spinth on Apr 15, 2010 12:37 PM

If you don't want that warning then simply turn it of.
A package-info.java file is there mostly to attach JavaDoc to the package itself.
If you don't need/want that, then the checkstyle warning is useless. Checkstyle (and similar tools) are meant to be tweaked to your needs and not used blindly.

TutWD_FlightList_Init .project file missing

Hello,
I am trying the TutWD_FlightList_Init tutorial.
I have downloaded the project.
For the first time I could successfully import this project into my workspace , however while creating model i was getting jjava.lang.NullPointerException.
So also when I tried to import this project for the second time into my workspace , while importing it said .project file missing.
Can anyone suggest the possible solutions to resolve the issues I am facing.
Thanks & Regards
Pooja

Hi,
Removing the .metadata folder and restarting NWDS fixed my NWDS as well.
I think you have to downloaded TutWD_FlightList_Init this application in SDN right. May be that application having some problem you can create application in own way. I think you are new to webdynpro JAVA right. Please read this [Document|http://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/web-dynpro-java/_web-dynpro-java/WDJava%20archive/Creating%20a%20Web%20Dynpro%20Application%20Accessing%20ABAP%20Functions.pdf]

3 Java Files Problem.

I got 3 java files let say sub.java, sub1.java and sub2.java.
the code for the sub files are as below with
import java.applet.*;
import java.awt.*;
on the top of each files.
sub2.java
=======
public class sub2{
String txt;
int x, y;
void setting(String objStr, int StartX, int StartY){
txt = objStr;
x = StartX;
y = StartY;
public void paint(Graphics g){
g.setColor(Color.blue);
g.drawString(txt, x, y);
sub1.java
=======
public class sub1{
sub2 chair;
String txt;
public void init(){
txt = "Oracle";
chair = new sub2();
public void paint(Graphics g){
chair.setting(txt, 20, 20);
chair.paint(g);
chair.setting(txt, 20, 40);
chair.paint(g);
chair.setting(txt, 20, 60);
chair.paint(g);
sub.java
======
public class sub extends Applet{
sub1 room;
public void init(){
room = new sub1();
public void paint(Graphics g){
room.paint(g);
room.paint(g);
All files can be compiled but i can't run sub.java
where i expect it to paint 6 "Oracle" string.
Anybody can help me?

In your class sub.java, you created a new sub1 object (1) without calling its init() method afterwards.
sub.java
======
public class sub extends Applet{
sub1 room;
public void init(){
(1) room = new sub1();
room.init(); // here is the missing line
Because the init method of sub1 (2) has not been called,
its sub2 instance (chair) won't be created and remains null.
I guess you'll get a NullPointerException at (3) when running the Applet.
sub1.java
=======
public class sub1{
sub2 chair;
String txt;
(2) public void init(){
txt = "Oracle";
chair = new sub2();
public void paint(Graphics g){
chair.setting(txt, 20, 20);(3)
chair.paint(g);
chair.setting(txt, 20, 40);
chair.paint(g);
chair.setting(txt, 20, 60);
chair.paint(g);
I hope this helps...

Calling a method from another Java file.

I think I'm doing this right, but I'm obviously going wrong somewhere.
In order to not have one big long java file, I've created one main one to execute the program, and another to do some of the functions. I'm using eclipse, btw.
In the main file, I have
currentTB = getActiveTB(playerArea);If it works, it should get send the player area variable to the getActiveTB method, and store the value it returns in the currentTB variable, right?
In the other file, I have;
package scenes;
public class sceneIndex {
     private TerrainBlock getActiveTB(String areaCode) {
          TerrainBlock tBlock = new TerrainBlock();
                 **DOES STUFF**
          return tBlock;
}I have it set up so the second file is in the source folder "resources" and the package "scenes." The problem is I'm not calling it properly. I'm missing something simple, I think. The only error I'm getting is;
The method getActiveTB(String) is undefined...
Where am I screwing up?
EDIT: Yeah, I'm a rookie here trying to figure it out on my own. My computer science courses, so far, conveniently all consist of just one big java file. Easier to write, sure, but not very efficient/organized.

Yeah, so this is still pissing me off. I'm not sure what else to do. I've tried this a million different ways, in both eclipse and netbeans. Whatever.

               pTexture.addTexture(new ImageIcon(SceneIndex.class.getClassLoader().getResource("img/grass.gif")), -128, 0, 128);
               pTexture.addTexture(new ImageIcon(SceneIndex.class.getClassLoader().getResource("img/dirt.jpg")), 0, 128, 255);
               pTexture.addTexture(new ImageIcon(SceneIndex.class.getClassLoader().getResource("img/granite.jpg")), 128, 255, 384);
               pTexture.createTexture(64);

               TextureState tState = display.getRenderer().createTextureState();
               Texture t1 = TextureManager.loadTexture(pTexture.getImageIcon().getImage(), Texture.MM_LINEAR_LINEAR, Texture.FM_LINEAR, true);
               tState.setTexture(t1, 0);
               tBlock.setRenderState(tState);
          return tBlock;
}Again, I've tried this a few different ways, and I either get a "Could Not Find Symbol" error referring to the getActiveTB(playerArea); in Main, or it just says java.lang.NoClassDefFoundError: and Exception in thread "main".
Whatever.

Managing java files and packages

Hi,
I am just starting out with java and have reached the stage where I want to store my files in packages and the correct directory structure. I have read through the sun link below and have a question they seam to miss. They say that .java and .class files should be kept in separate places. ie sources and classes directories with the package directory names below. But I have found that unless you have the .class files you are referencing in the same directory as the .java files when you come to compile you will get an error so they have to be stored in the same directory???.. Does this make sence or have I gotten it all wrong.
Thanks

You should put path containing your classes in your classpath. There is a -classpath option in javac.

Java File and JSP Page

I am to create a link verification program -- a simple java file with the database connection & some business logic and a JSP page that instantiates the my java file. It won't work. Everytime I run the jsp page, it gives me java.lang.NullPointerException. Can anyone give me some directions? The web server I am using is JRun.
Thank you
Below are my code:

How to compile Java files using Ant in Eclipse

Hi All ,
I would like to compile all Java files using Ant in Eclipse.Since am very new to Ant and Eclipse can someone help me to create a build.xml file and let me know how to compile all the java files.
For ex , I have placed my java files inside the path C:\HEC\Terab.Initially the Terab folder holds 7 jar files which i had decompiled using JD compiler and placed the unzipped 7 folders (which contains the java files ).Now i have imported the HEC project into Eclipse using New ->Project ->Java Project.after importig it throwed me an error saying missing jar files.again i copied the jar files and placed inside Terab folder with other 7 folder.
Now How i can compile the java files and convert in to class files.Then after compiling the files i will again need to jar all the 7 folder.
Please tell me the steps i need to follow.How to write an build.xml file ? where i should keep it ? only one build.xml file is enough or should i write 7 build.xml file for each folder ? Please help me out...
Thanks & Regards

You are missing a closing parens. You have :
if(type = "Return")
FlightServiceClient client = new FlightServiceClient(ServerFlightServiceURL);
ArrayList list = client.getFlight(arr, des, FDat, TDat, type, clas, adult, child);
Iterator it = list.iterator();
while (it.hasNext()){Which opens two parens but you only have one closing parens
</tr>

How to convert .class files to .java files

Hi,
I want to convert .class files to .java files. Is there is any software for that doing except Dj DCompiler? Because if i am using this i am not getting proper code i mean as it is available in the file.
I tried by writing simple java file and i compiled Sample.java file and i got a .class file then i converted this Sample.class to Sample.java file by using DjDcompiler but i was missing some statements i need entire code that is available in Sample.java file. Please tell me any other software for that doing.
Thank you in advance
