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\

Exception in thread "main" java.lang.NoClassDefFoundError: vXmx512m
Caused by: java.lang.ClassNotFoundException: vXmx512m

        at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
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"

Hi,
when i execute startWebLogic.cmd
i am getting error message :

Thanks.

Hi,
Check what you put in the setDomainEnv.cmd.
Secondly try to clear tmp and cache folder of your adminserver once before next start.

Exception in thread "main" java.lang.NoClassDefFoundError: weblogic/Server

Dear Sir/Madam
I downloaded the Weblogic610 server five times, and when I install it on my Linux
box (RedHat 7.1), I always met the exception like:
Exception in thread "main" java.lang.NoClassDefFoundError: weblogic/Server
When I check with lib directory, there is weblogic.jar here, but the file looks
was damaged, the file size is ok, but I can't open it by use jar tool or other
tools.
Some packeage is very strange, after my downloaded, and install, there are only
a few files in lib directory and some subdirectory and weblogic.jar is missing,
but the download is normal.
So, I hope who guy have similar experience, please let me know.
Thank you
Cidy

Hi Raj,
Could you provide more information from the log; is there a full
traceback. A first step may be to use the latest service pack [1].
Also you might try your question in the management newsgroup [2] or
contact our outsanding support group [3].
Hope this is of some value,

Java.exe error - Exception in thread "main" java.lang.NoClassDefFoundError:

I've just started to take on java, and some examples from my learning source
show the
javac.exe fileincluded.java
to
java.exe fileincluded
method. Although I can compile fine, when I go to run I get a java.exe error - Exception in thread "main" java.lang.NoClassDefFoundError:.
I thought it was an environment variable problem as I'm running win xp.
I've gotten the bin directory included, and I've previously had visual studio .net installed
so the INCLUDE and LIB variables are set to those directories. I've tried to attach the java /lib and /bin directories by ";C:\PROGRAM FILES\JAVA\JDK1.5.0_02\LIB" etc,
and that didn't work. What can I do to fix this problem?

I get the I/O exception while reading: D:\Java\HelloApplet (The system cannot find the file specified). I have previously compiled HelloApplet.java into HelloApplet.class using javac.exe
the two include statements in the sample HelloApplet I'm using are
import java.applet.*;
import java.awt.*;
I also have a ComponentEventTest.java file which I've made into a class with these two
include statements:
import java.awt.*;
import java.awt.event.*;
I can however compile .java files which have no include statements.
I take it that my classpath is not set correctly. Like I said earlier, I'm using winxp
and trying to set the classpath variable under system. I have tried under user too. The path names I've tried setting are C:\Program Files\Java\jdk1.5.0_02\, C:\Program Files\Java\jdk1.5.0_02\lib, C:\Program Files\Java\jdk1.5.0_02\include, and C:\Program Files\Java\jdk1.5.0_02\;C:\Program Files\Java\jdk1.5.0_02\lib;C:\Program Files\Java\jdk1.5.0_02\include.
How can I correct this? If it's possible, I would like to set a variable in windows
versus having to type extra commands at the command prompt everytime I try
to run a java class with java.exe. Any help would be much appreciated

Can't get by Exception in thread "main" java.lang.NoClassDefFoundError:

With the help of someone on the Forum, I resolved the class reference that was giving me fits. But I'm still getting
Exception in thread "main" java.lang.NoClassDefFoundError: jform_example
This is all the information that I get. It compiles and runs from SunOne IDE, but not from command line. What Class reference or whatever am I missing? I don't know that my environment variables are correct. I've tried to find a comprehensive list of steps to do so, but without success. So I've been winging it.
What information should I provide that will help you help me. I'm spending WAY to much time on this issue.
Help!
Gary

This error occurs when the java.exe program can not find the class whose name was specified on the command line. Note that the argument to java.exe is the class name not a file name. java.exe tried to find a file whose name is jform_example.class. It searched the directories that were in your system's Classpath environment variable at the time of command execution. It didn't find the file.
So the file jform_example.class must exist, must be named exactly as specified (java is case sensitive so Jform_Example won't work), the source code must not start with a package statement (a package statement means the class name is package_name.jform_example), and the jform_example.class must be in a directory that's in your Classpath.
Try to CD to the directory where jform_example.class is located and use the command "java -classpath . jform_example" This uses the current directory as the Classpath during execution.

SQLJ error: "Exception in thread main java.lang.NoClassDefFoundError: sqlj/

Hi,
I am new to SQLJ. Now, in my PC (with Win98), I have JDK 1.2 and Oracle 8i (personal edition). I have used Java and Oracle in my PC without any problem. Now, I am going to learn SQLJ in order to create a java program to access Oracle database. What I have done is to set up several classpaths in DOS:
SET classpath=C:\ora_program\sqlj\lib\translator.zip;
SET classpath=C:\ora_program\sqlj\lib\runtime.zip;
SET classpath=C:\ora_program\sqlj\lib\runtime12.zip;
SET classpath=C:\ora_program\jdbc\lib\classes12.zip;
The code of my program is:
import java.sql.Date;
import java.sql.SQLException;
import oracle.sqlj.runtime.Oracle;
import java.util.Date;
public class Hello{
     public static void main(String[] args){
          java.sql.Date current_date;
          try{
               // connect to the db
               Oracle.connect(
                    "C:\ora_program\bin",
                    "system",
                    "manager");
               // get the current date from the database
               #sql{SELECT sysdate INTO :current_date FROM dual};
               // display message
               System.out.println("Hello, the current date is: "+ current_date);
          catch(SQLException e){
               System.err.println("sqlException: "+e);
          finally{
               try{
                    Oracle.close();
               catch(SQLException e){
                    System.err.println("sqlException: "+e);
And then I compile my program in DOS with the typing: sqlj Hello.sqlj
The program cannot be compiled and the error message is:
"Exception in thread main java.lang.NoClassDefFoundError: sqlj/tools/Sqlj"
It indicates that the SQLJ translator class files cannot be found.
I have set up the classpath in DOS (see above). How does the error come? Please help. Thanks.

SET classpath=C:\ora_program\sqlj\lib\runtime12.zip;
SET classpath=C:\ora_program\jdbc\lib\classes12.zip;
The above only sets the classpath to the last value. You need to use the following.
SET classpath=%classpath%;C:\ora_program\sqlj\lib\runtime.zip;

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

Hi
I have seen this problem on a few forums but have not found an answer that works for me, sorry if missed it!!
The command I am giving is:
C:\Program Files\Rococo\ImprontoSimulator\examples\echo\bin>echo-server
Exception in thread "main" java.lang.NoClassDefFoundError: com/rococosoft/impronto/examples/echo/EchoServer
this runs the following batch file:
@echo off
set CLASSPATH=
set CLASSPATH=%SIMULATOR_HOME%\lib\isim_j2se.jar;%CLASSPATH%
set CLASSPATH=%SIMULATOR_HOME%\lib\log4j.jar;%CLASSPATH%
set CLASSPATH=%SIMULATOR_HOME%\examples\echo\lib\echo.jar;%CLASSPATH%
java -classpath "%CLASSPATH%" com.rococosoft.impronto.examples.echo.EchoServer
this is where I assume all the CLASSPATH's are set.
Any help would be very much appreciated.
Thanks
Nitin

Once you have defined your classpath as an environment variable, it shouldn't be necessary to include it (or quote it) within the command line. In other words,
c:\> java EchoServer
should have worked. However, I suspect the reason the batch script doesn't work might be because %SIMULATOR_HOME% isn't defined? If Java can't find any of the libraries, then it can't find a class EchoServer that contains a main() function to call, resulting in the error message you've received.

Dear People,
I would really kindly welocme any help on the following error problem:
Exception in thread "main" java.lang.NoClassDefFoundError: CoreUpdate
The program compiles successfully and there are no errors generated from that but I get the above error when I try to run it. I have scanned over all the previous replies that have been posted for this sort of error and have tried all the following solutions:
1) Set classpath to point to the bin and lib directories of where the JDK1.3.1 is installed in.
2) Have actually placed in my classpath the EXACT directory to which the tools.jar file is located (within the lib directory).
So WHAT ELSE is there to do?? I am really frustrated with this problem and I have re-started my computer in order to boot the classpath into gear but still no joy!
I am running Win2k so do I actually have to go into my autoexec.bat file and type the classpath in there aswell(to which I havent done) or can I just go through my computer on my desktop and then to environment variables and set it up in there (to which I have done already and nopthing seems to work)?
PLEASE PLEASE PLEASE help!! I very frustated girl programmer!!!
Any help would be very much appreciated!

HELP Needed with this error: Exception in thread "main" java.lang.NoClass

Folks,
I am having a problem connecting to my MSDE SQL 2000 DB on a WindowsXP pro. environment. I am learning Java and writing a small test prgm to connect the the database. The code compiles ok, but when I try to execute it i keep getting this error:
"Exception in thread "main" java.lang.NoClassDefFoundError: Test1"
I am using the Microsoft jdbc driver and my CLASSPATH is setup correctly, I've also noticed that several people have complained about this error, but have not seen any solutions....can someone help ?
Here is the one of the test programs that I am using:
import java.sql.*;
* Microsoft SQL Server JDBC test program
public class Test1 {
public Test1() throws Exception {
// Get connection
DriverManager.registerDriver(new
com.microsoft.jdbc.sqlserver.SQLServerDriver());
Connection connection = DriverManager.getConnection(
"jdbc:microsoft:sqlserver://LAPTOP01:1433","sa","sqladmin");
if (connection != null) {
System.out.println();
System.out.println("Successfully connected");
System.out.println();
// Meta data
DatabaseMetaData meta = connection.getMetaData();
System.out.println("\nDriver Information");
System.out.println("Driver Name: "
+ meta.getDriverName());
System.out.println("Driver Version: "
+ meta.getDriverVersion());
System.out.println("\nDatabase Information ");

+ meta.getDatabaseProductName());
System.out.println("Database Version: "+
meta.getDatabaseProductVersion());
} // Test
public static void main (String args[]) throws Exception {
Test1 test = new Test1();

I want to say that there was nothing wrong
with my classpath config., I am still not sure why
that didn't work, there is what I did to resolved
this issue.You can say that all you like but if you are getting NoClassDefFound errors, that's because the class associated with the error is not in your classpath.
(For future reference: you will find it easier to solve problems if you assume that the problem is your fault, instead of trying to blame something else. It almost always is your fault -- at least that's been my experience.)
1. I had to set my DB connection protocol to TCP/IP
(this was not the default), this was done by running
the
file "svrnetcn.exe" and then in the SQL Server Network
Utility window, enable TCP/IP and set the port to
1433.Irrelevant to the classpath problem.
2. I then copied all three of the Microsoft JDBC
driver files to the ..\jre\lib\ext dir of my jdk
installed dir.The classpath always includes all jar files in this directory. That's why doing that fixed your problem. My bet is that you didn't have the jar file containing the driver in your classpath before, you just had the directory containing that jar file.
3. Updated my OS path to located these files
and....BINGO! (that simple)Unnecessary for solving classpath problems.
4. Took a crash course on JDBC & basic Java and now I
have created my database, all tables, scripts,
stored procedures and can read/write and do all kinds
of neat stuff.All's well that ends well. After a few months you'll wonder what all the fuss was about.

Error after compile Exception in thread "main" java.lang.NoClassDefFoundErr

Hi I am very new to Java programming, right now I am using a mac os 10.49
I can create java documents using bbedit and then they compile when i type
javac.
But when i type java *.java I get the following error
Exception in thread "main" java.lang.NoClassDefFoundError
If I type java "filename"
without the .java at the end of the file the terminal has no response
I understand i am supposed to some how set the classpath but i do not know how to do this
Also I can create and compile and then run my java in the eclipse program that i have installed, but not from terminal and im not sure why.
Thanks for the help.

I understand i am supposed to some how set the classpath but i do not know how
to do thisThere is no need to set a system variable CLASSPATH, it is inflexible to do so, and it can lead to unpredictable behaviour.
You should be able to compile and run programs from the command line, specifying the classpath as part of the commands you use.
(1) For instance, you can create a file HelloWorld.java with the following contents:public class HelloWorld {
public static void main(String args[]) {
System.out.println("Hello world");
}(2) From the command line (console) navigate to the folder (directory) containing this file and compile it with the commandjavac -cp . HelloWorld.javaThe "-cp ." part is what specifies the classpath. Note that it is a file that is being compiled so we specify the actual file name including the extension. At this point you should be able to check that the HelloWorld.class file has been created.
(3) From the same folder (directory) you run the program withjava -cp . HelloWorldThe classpath is being specified in the same way as before. It is a class that is being invoked, so we don't specify a filename. (much less use wildcards like *).
