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"

Error while compiling java file

Hi, im newby in java,
i was trying to compile java files, and after that i will use it in JSP as javabean.
I have 2 files already, the first file is a connection code, and its compiled successfully, it looks like this
i named this as ConnectionBean.java
package my_package;
import java.sql.*;
public class ConnectionBean {
     private Connection con;
     private static final String driver = "org.postgresql.Driver";
     private static final String url = "jdbc:postgresql://localhost:5432/PSQLDS";
     private static final String username = "postgres";
     private static final String password = "mypassword";
     public ConnectionBean() {
     public Connection logOn() {
          try {
               Class.forName(driver); con = DriverManager.getConnection(url, username, password); }
          catch(ClassNotFoundException e) {
               System.err.println("ConnectionBean: driver unavailable..."); con = null; }
          catch (SQLException e) {
               System.err.println("ConnectionBean: driver not loaded..."); con = null; }
          return con;
     public void logOff() {
          try {
               con.close(); }
          catch (Exception e) {
               e.printStackTrace(); }
as you can see above im using "package", and yes i have manage to put all my java files within the correct path (ROOT\WEB-INF\classes\my_package)
And also, i have test this class as javabean on JSP file and it works.
There for i continue to create the second java file, as a purpose to create a back engine for JSP. I use the same package as ConnectionBean.java, it looks like this
i named this as ListPageEngine.java
package my_package;
import java.beans.*;
import java.sql.*;
public class ListPageEngine {
     public static void main(String[] args) {
          ConnectionBean conBean = new ConnectionBean();}
on compiling process using command "javac ListPageEngine.java", i get this error message
ListPageEngine.java:11: cannot find symbol
symbol : class ConnectionBean
location: class my_package.ListPageEngine
ConnectionBean conBean = new ConnectionBean();}
^
ListPageEngine.java:11: cannot find symbol
symbol : class ConnectionBean
location: class my_package.ListPageEngine
ConnectionBean conBean = new ConnectionBean();}
^
2 errors
I think, i am pretty much sure that all my configuration (wheater its Apache TomCat, Environment Variable or PostgreSQL server) was good, as a prove, i was able to use ConnectionBean.class in my JSP file.
I susspect the problem is related with "package", seems i cannot use ConnectionBean class within ListPageEngine class when i use package.
For another information, i didn't install such thing as J2EE, i only install JDK 1.5, i also guess this might be the cause.
Right now im all stuck, i try to find thread which might be related with my problem but i failed to find it, most of them get the same answer by UncleSAM which are
Try the following forum (about JSP technology)
http://forum.java.sun.com/forum.jspa?forumID=45
JavaBeans spec contains nothing about JSP, but JSP spec describes using of beans.
i hope my question is clear so anyone who might have experience or clue with this problem might be able to help me.
Thanks before

finally folks, i found answer to my own problem hehehehe..
the problem is on the compiling command (javac ... my_file.java), i found that i need to add some parameter on the command to make it works.
This problem solved.

but the error is: "cannot access javacard.framework.APDU"
What am I wrong?
2. I use eclipse 3.3.2, eclipse jcde 0.1, java_card_kit-2_2_2, jdk1.6.0 to compile java card applet. The compilation from .java to .class was no problem, but from the .class to .cap has problem:

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

Error while Building Jar files using [ejbc]

Hi,
I am building EJB's using [ant ejbc] for upgrade from Weblogic 6.1 to Weblogic 10.0. The code gets build fine but when creating the Jar file it is throwing me the following error :-
[ejbc] Loading properties file: /C:/dev/MarketingOne/thirdparty/sms/lib/logging.//config/logging.properties
[ejbc] SMS_ERROR:
[ejbc] Properties:
[ejbc] - Failed to load properties file: /C:/dev/MarketingOne/thirdparty/sms/lib/logging.//config/logging.properties
[ejbc] java.io.FileNotFoundException: C:\dev\MarketingOne\thirdparty\sms\lib\logging.\config\logging.properties (The system cannot find the path specified)
[ejbc] - Either invalid SMS_HOME: /C:/dev/MarketingOne/thirdparty/sms/lib/logging./ or invalid <I>SERVICE</I>_P
ROPERTIES_FILE_NAME
[ejbc] at java.io.FileInputStream.open(Native Method)
[ejbc] please set SMS_HOME using -D option at JVM start up.
Can anybody provide me with a solution for this as the path mentioned for SMS Logging.properties file is correct..??

Actually the folder 'lib' consists of a logging Executable Jar file and the SMS folder consists of 'config' and 'lib' folders. Inside the 'config folder is a logging.properties file.
But Actually I am not getting any idea as to from where this command is being triggered because my targets.xml file does not have any such command whereas it just builds all the files and then creates the jar file.
Is it a problem of using EJB 2.0 in Weblogic 10.0 environment or jdk1.5..??

Error while deploying war file using JRUN JMC

Hi,
I am getting "Deployment service failed to deploy war file" Error
while trying to deploy a war file using JRUN Mgmt console.
If anyone has any idea about it, please help.
Thanks
Jit

Check the logs. There might be a detailed exception in it. My guess is that it might have something to do with the deployment descriptors.
If you could post the deployment descriptors and the exception stack trace, it would be easier to figure out.

After transport all the SWDC to another client, i try to deploy the sca file using the tcode Sdoe_upload_archive and i am getting this error : " DataObject Transid '005056C000081DDD9BA073B0B4974E15' doesnot exist/is inactive in DOE.
Can anyone pls share some idea how to resolve this problem? thank you
Regards,
Joan

Hi,
Were you able to reach the screen mobile component administration?
From sap easy access menu>click the user menu>Data Orchestration Admin and Mon portal-->administration link
You mean you are not able to find the MCD at all?I guess your mobile component will be of type application.
May be you can scan through the MCDs listed after a wild card search and check the dataobject dependencies for each.
Some how the MCD that you are trying to upload contains dataobjects that are not present in the system.
You mentioned 'After transport all the SWDC to another client' , what exactly was done in this step?

Liji

Any one pls tell me how to slove my problem
thanks in advance

hi
i got the solution. its working now
but blowfish key ranges from 56 to448
while i am writing the code as
KeyGenerator keyGenerator = KeyGenerator.getInstance("Blowfish");
keyGenerator.init(448);
this code is generating the key upto 448 bits
but coming to encoding or decode section key length is not accepting
cipher.init(Cipher.ENCRYPT_MODE, key);
Exception in thread "main" java.security.InvalidKeyException: Illegal key size or default parameters

i am getting this error
what is the solution for this type of exception.
thank you
