I know, maybe this isnt the right topic, but please help me !!
And I'm not the best PC programmer but I know the basics :S

This is a support forum for programming Java, not for any and all Java-based software.
Your best bet is to contact the author of the software.
How did you try to run the program?

Exception in thread "main" java.lang.NoClassDefFoundError

Am using java 1.3.1 on Red Hat Linux 7.1
i get this error
Exception in thread "main" java.lang.NoClassDefFoundError
while running a simple program HelloWorld.java
help

When you use the "java" command, the only required argument is the name of the class that you want to execute. This argument must be a class name, not a file name, and class names are case sensitive. For example, "java HelloWorld.java" won't work because the class name isn't HelloWorld.java, it's HelloWorld. Similarly, "java helloworld" won't work because a class defined as "public class HelloWorld {" is not named helloworld due to case sensitivity. Finally, the .class file must be in a directory that is in the Classpath - that's where java.exe searches to find the file that contains the class.

On starting WebLogic getting Error : Listening for transport dt_socket at address: 8453 Exception in thread "main" java.lang.NoClassDefFoundError: vXmx512m

Hi,
system i am using for Oracle SOA is :
Windows 64 Bit
i5 Processor
6 GB RAM
29 GB on C Drive is already free after installation of all SOA related products.
I have installed wlserver_10.3 for SOA 11g Development purpose and followed exact installation sequence and procedure as mention in oracle documentation
i created domain also and every thing look correct but after installation procedure there are "Additional actions required just after every thing installed" :
setting memory limit
starting weblogic server (Admin Server)
starting weblogic managed server
and so on
now Problem is when i execute C:\Oracle\Middleware\user_projects\domains\soa_div_domain\bin startWebLogic.cmd
as mention in oracle documentation i am getting following error message : (i have only included last error lines instead of complete console log)
oConsole= -Dweblogic.ext.dirs=C:\Oracle\MIDDLE~1\patch_wls1036\profiles\default\

Could not find the main class: ++Xmx512m. Program will exit.
Now to resolve this what i already tried are :
I change JAVA_HOME and PATH to jdk6 which came with web logic installer
Location is at :
JAVA_HOME : C:\Oracle\Middleware\jdk160_29
PATH : C:\Oracle\Middleware\jdk160_29\bin
The above dose not include any space between path
I ran the startWebLogic.cmd and got same error
After that I also added
CLASSPATH : C:\Oracle\Middleware\jdk160_29\lib\tool.jar;C:\Oracle\Middleware\wlserver_10.3\server\lib\weblogic.jar;C:\Oracle\Middleware\jdk160_29\bin
WL_HOME: C:\Oracle\Middleware\wlserver_10.3
I ran the startWebLogic.cmd and got same error
I also used earlier path which I used with eclipse when I was working on other java development.
JAVA_HOME : C:\Program Files\Java\jdk1.7.0_21
PATH : C:\Program Files\Java\jdk1.7.0_21\bin
I ran the startWebLogic.cmd and got same error
Then I also gave PATH: C:\Oracle\Middleware\wlserver_10.3\server\lib      (including the existing one using ; )
I ran the startWebLogic.cmd and got same error
Now may be there is a file called setSOADomainEnv.cmd in
< C:\Oracle\Middleware\user_projects\domains\soa_div_domain\bin\ setSOADomainEnv.cmd>
That include some values for memory set :
set JAVA_OPTIONS=%JAVA_OPTIONS%
set DEFAULT_MEM_ARGS=-Xms512m –Xmx512m
set PORT_MEM_ARGS=-Xms512m –Xmx768m
if "%JAVA_VENDOR%" == "Oracle" goto OracleJVM
set DEFAULT_MEM_ARGS=%DEFAULT_MEM_ARGS% -XX:PermSize=128m -XX:MaxPermSize=768m
set PORT_MEM_ARGS=%PORT_MEM_ARGS% -XX:PermSize=256m -XX:MaxPermSize=768m
now as I change the red highlighted value to 512 value because I have less memory resource and I checked in installation documentation to change the above red highlighted value to 512 original is 1024 which is too high and it was crating problem and showing memory space problem so I change it to 512 and now I am not getting that memory space problem error but may be the above error is related with change value in setSOADomainEnv.cmd file or not
Following are my domain, weblogic and soa home directory path and all these path are exactly what it suppose to be according to Oracle Installation Documentation:
WebLogic :
C:\Oracle\Middleware\wlserver_10.3
C:\Oracle\Middleware\coherence_3.7
C:\Oracle\Middleware\oepe_11.1.1.8.0
SOA Oracle Home Directory :
C:\Oracle\Middleware\Oracle_SOA1
OSB Home Location :
C:\Oracle\Middleware\Oracle_OSB1
Domain name : soa_div_domain
Domain Location :       C:\Oracle\Middleware\user_projects\domains
Application Location : C:\Oracle\Middleware\user_projects\applications
Domain Location:        C:\Oracle\Middleware\user_projects\domains\soa_div_domain
form here i am trying to start weblogic : C:\Oracle\Middleware\user_projects\domains\soa_div_domain\bin\startWebLogic.cmd
Please tell me any body want more details.
Thanks.

I think you are missing a character '-'
USER_MEM_ARGS="Xms512m -Xmx512m -XX:MaxPermSize=128m"Add this character like follows
"-Xms512m -Xmx512m -XX:MaxPermSize=128m"

I'm assuming you're using JWSDP 1.6 as I see Fastinfoset.jar in your list. You are missing some jar files in your classpath there. The best way to know what you need is to look at the release notes for JWSDP 1.6. Since you're building a web serivce start with the table in there and lookup JAX-RPC. It'll show you what jar files are needed and what other libraries are needed. Now depending on what you're doing you don't really need all those.
For sure you're missing jsr173_api.jar which is where I believe that class you need is located. This is in the JWSDP_1_6\sjsxp\lib directory. You will probably need the other jar thats in there too. Best bet is to follow the dependancy chart in the release notes.
This should get you going.

There is no errors by the compiling. But when i want to run the application follows:
Exception in thread "main" java.lang.NoClassDefFoundError: Springer
Can someone help me??
I need that program!

A few more comments on your code...
- In Java arrays index start at 0 not at 1. You may want to change your init() method accordingly.
- In init() the parameter nquad hide the field of the same name so the assignment you make at the end of the method is lost
Hope this help,
Eric

Debian jdk 1.5 Exception in thread "main" java.lang.NoClassDefFoundError:

Hi people!
My problem is that I"ve installed jdk 1.5 on Debian (without problems) and I want to run my java program. I get
Exception in thread "main" java.lang.NoClassDefFoundError: /home/me/GermanAnnotations/build/classes/GermanAnnotations
although this class exists and runs perfectly under Windows.
Please, help!

This sounds like someone is including the ".class" in a class name. For example, when I compile a java application, it may be in a package like "tld.mydomain.package". When I run it I might say:
java -classpath classes tld.mydomain.package.ClassNamebut a common mistake is to include the ".class":
java -classpath classes tld.mydomain.package.ClassName.classwhich would produce an output similar to what you're seeing.

Exception in thread "main" java.lang.NoClassDefFoundError: Emp/class

Dear all,
It occur 'Exception in thread "main" java.lang.NoClassDefFoundError: Emp/class' error when I test a oracle java sample.I've already SET CLASSPATH=C:\ORACLE\JDBC\LIB\CLASSE~1.ZIP.
following is the source code:
import java.sql.*;
class Emp
public static void main (String args [])
throws SQLException
// Load the Oracle JDBC driver
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
// Connect to the database
// You must put a database name after the @ sign in the connection URL.
// You can use either the fully specified SQL*net syntax or a short cut
// syntax as <host>:<port>:<sid>. The example uses the short cut syntax.
Connection conn =
DriverManager.getConnection ("jdbc:oracle:oci8:@localhost:1521:orcl",
"scott", "tiger");
// Create a Statement
Statement stmt = conn.createStatement ();
// Select the ENAME column from the EMP table
ResultSet rset = stmt.executeQuery ("select ENAME from EMP");
// Iterate through the result and print the employee names
while (rset.next ())
System.out.println (rset.getString (1));
Can you tell me what should also be set in classpath?
thanks in advance.

You are right, the program is absolutely correct and I've run it before.but why set PATH=%PATH%;C:\ORACLE\JDBC\LIB\CLASSE~1.ZIP?I don't think it is correct.
I've ever run this jdbc program before and remeber only set classpath(path is also be set only for run executable program, for example set path=%path%;c:\j2sdk\bin),
I think the only difference with before is:
1,oracle version is changed from enterprise version to personal version
2,OS is changed from NT to windows 98
but i dont know if it lead to problem and can you give me some advice?

pl guide for this.

Put the hsqldb JAR file into your classpath. I suspect Mr Singh was using ".." when he should have been using "." in the classpath string, but even if he wasn't his classpath issue's not that likely to be identical to yours.

Exception in thread "main" java.lang.NoClassDefFoundError: Helloworld

Hi Java Experts,
I am at a lost to how Java searches for all the classes when running a program. Below are the following steps I have taken to try a simple basic HelloWorld.java program on the command prompt on Windows XP (SP2) platform:
( i ) Installed both jdk1.5.0_09 and Netbeans IDE 5.0 and working properly.
( ii ) The source file is located in F:\Documents and Settings\abc\HeadFirstDesignPattern\src\ch11 and the compiled file is in F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes\ch11 which was compiled in Netbeans.
( iii ) No problem compiling & running this program in Netbeans.
( iv ) The RUN CLASSPATH in Netbeans is F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes.
( v ) No CLASSPATH variable has been set.
( vi ) The HelloWorld program looks like this:
package ch11;
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World!");
( vi ) Got the message
"Exception in thread "main" java.lang.NoClassDefFoundError: HelloWorld"
when running a combination of the following Java commands:
( a ) cd F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes
( b ) java HelloWorld, or
java -cp . HelloWorld or java -cp "." HelloWorld, or
java -cp F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes HelloWorld or "F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes" HelloWorld, or
java -cp F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes;. HelloWorld or "F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes";. HelloWorld, or
java -cp "F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes";. HelloWorld or "F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes";"." HelloWorld, or
java -cp "F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes";. HelloWorld or "F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes";"." ch11\HelloWorld.
It is the package location which is a subdirectory of F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes which caused Java not to find this program. I had no problem running it if the HelloWorld.java was moved one level up. ie from F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes\ch11 to F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes.
I have written Java in the last year mostly on Netbeans without any problem running them.
The reason for having to learn to run Java on the command line is so that I could add arguments to the program which I couldn't do in Netbeans just yet.
I have gone through a lot of the articles from Java forums, Google searches but yet to have found a solution.
Many thanks,
Netbeans Fan

I am getting the same problem when running the same program on a Fedora 4.0 (Redhat Linux 10) system, together with Netbeans 5.5 and JDK1.5.0_09. Again, I have no such problem when running the same program in Netbeans.
Here are the steps that I have taken as follows:
