D:\>javac AnimalTest.java
.\Cat.java:4: illegal start of expression
^You really need to start to understand what you are doing. Look at the error, it even points to what the error is. Look at where this bracket appears in your code and think to yourself "Should that be there or should it be something else" Once you fix that, the other errors will probably disappear.

Problems Running Java Programs

I usually use Forte for Java to run and compile my java programs, but now I am trying to compile and run using the command line. When I compile something it runs fine. However when I attempt to run something it gives me a NoClassDefFound Error. For example when I have this program in package greetings.
D:\JDK_Forte\forte4j\Development>javac greetings\Hello.java
D:\JDK_Forte\forte4j\Development>java greetings.Hello
Exception in thread "main" java.lang.NoClassDefFoundError: greetings/Hello
So it compiles fine but does not run. Is something possibly not set up correctly? I don't know what could be wrong. Thanks for any help you can give.

try
D:\JDK_Forte\forte4j\Development>java -classpath .
greetings.HelloI tried that and I got this error don't know if this helps at all....
D:\JDK_Forte\forte4j\Development>java -classpath . greetings.Hello

Problem running Java programs

Hello,
Have recently re-formatted my hard drive and re-installed Windows XP. I have installed the 1.4.2_03 SDK and any Java program I run just shows a grey window, with the toolbar as usual on top. I have un-installed it and re-installed it, and even tried installing the 1.5.0 beta, but it still keeps happening. Even the Jav Control Panel just shows the grey window.
Does anyone know how to fix this? Or have any suggestions I may try?
Thanks.

This is a fresh install of XP. But if I can't figure it out soon, I'll probably re-format and re-install again.

MS Access Date problem (from Java program)

I have written an app. in Java that reads & writes data from a MS Access database.
I am trying to write an insert class which will add a row of data to one of my database tables - which contains Date fields.
My problem is that I can update the text fields, but not Date fields - every time I try my program throws an exception:
java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver] Syntax error in INSERT INTO statement
My simplified code reads as:
try {
Statement insertStatement = databaseConnection.createStatement();
String query = "INSERT INTO myTable(jobId, employeeId, date) VALUES('11', '1', " + "'13/11/2006'" + ");";
insertStatement.execute(query);
} //close, etc. etc.
If I remove the date info from the query, the program executes successfully. I appreciate my problem might be related to the formatting of the date in Access, and if not a 'proper' Java question I give my apologies.
I have attempted several formats of the date with no success or variation in the exception.
I am, however, completely stuck and would appreciate any and all help given.
Regards and thanks
David

I have amended my code to use a preparedStatement, but on execution I have the same problem.
My code is as follows:
PreparedStatement pstmt = null;
try {
String query = "INSERT INTO myTable (jobId, employeeId, date) VALUES(?, ?, ?);";
pstmt = databaseConnection.prepareStatement(query);
pstmt.setString(1, "11");
pstmt.setString(2, "1");
java.sql.Date sqlDate = getCurrentJavaSqlDate();
pstmt.setDate(3, sqlDate);
// execute query, and return number of rows created
int rowCount = pstmt.executeUpdate();
System.out.println("rowCount=" + rowCount);
pstmt.close();
catch, etc. etc.
Any ideas or help most welcome
Regards
David

}If any kind people who can help me.
many thanks to you!

4 widgets???
maybe this is what you mean.
add this inside your actionPerformed method for the reset action
squareButton.setSelected(true);
colorComboBox.setSelectedIndex(0);
if not be more clear in your post.

Did you try debugging a break point (a debugging point) in the servlet and check where exactly you are getting an exception?

Typical problem - Will Java Runtime options help me ?

Hi,
We are using JInitiator to launch our application.When launching, this application downloads the ".JAR" files which are in server .I'm able to get the handle of the application and access all the Methods and properties from Visual Basic 6.0. But the problem is that I'm able to call methods which accepts only Integer or String as arguments.
I'm unable to call the methods which has argument type as Boolean [ Ex : Win.setVisible( Boolean b) ]. I tried passing all types of VB variables ,But I get "Type Mismatch Error" . I found an application which is similar to mine that uses "-Xbootclasspath" , "-Xrunmicsupp" , "MIC_CLASSES" & "_classload_hook" options to control Java applications by overriding some classes.
I created a new class with the same name but which has an extra function to accept string as a parameter [ Win.setVisible( String b) ] that enables me to call from VB. I want to Override my application's class with my class file which is in my local system. I want to override it because I'm supposed to change the class file in the server.
Is it possible to do my task using " java -Xbootclasspath" or something similar to that ? If so, Please tell me the way to do this. Please point me to some sites where in i can find the details about the above options that which the application similar to mine is using. Please help me,I will be very thankful to you guys.Hope to see your replies soon.
Thanks and Regards,
Srinivas.

D:\>javac AnimalTest.java
.\Cat.java:4: illegal start of expression
^You really need to start to understand what you are doing. Look at the error, it even points to what the error is. Look at where this bracket appears in your code and think to yourself "Should that be there or should it be something else" Once you fix that, the other errors will probably disappear.

Java programs not working.

I'm having problems running java programs. Whenever I open them, the window will open, but nothing will appear inside. The only parts of the program that appear, and only sometimes, will be the word "cancel" or "OK" where there should be buttons, but the rest of the program, including text boxes, other buttons, anything else, etc. will not load. Does anybody have any ideas as to what might be the problem? Thank you.

Hmmm. Both of those programs work fine on my machine. We're running the same version of the OS and the hardware shouldn't matter, but maybe someone with an Intel Mac like yours could try them and report on their results.
As a shot in the dark, you could run the standard maintenance routines like Repair Permissions and Repair Disk to see if that fixes your problem. Other than that, I don't know what to suggest. Sorry.

Compile correct but not run java programs

I have problem. Java program copile correctly but not run. I can't understand this one.
**this is the error**
Exception in thread "main" java.lang.NoClassDefFoundError: suminda
Caused by: java.lang.ClassNotFoundException: suminda

Could not find the main class: suminda. Program will exit.

The error is telling you that the jvm could not find a class named suminda. Are you aware that class names are case sensitive? Suminda is not the same as suminda for example.
This error usually happens when you haven't specified the classpath correctly. A simple thing to try isjava -cp . sumindaHere's some links that may help.

Problem while calling a Webservice from a Stand alone java program

Hello Everyone,
I am using a java program to call a webservice as follows. For this I have generated the client proxy definition for Stand alone proxy using NWDS.
Now when I call the method of the webservice I am getting the correct result but along with the result I am getting one error and one warning message in the output.
The java code to call the webservice is as follows.
public class ZMATRDESCProxyClient {
     public static void main(String[] args) throws Exception {
          Z_MATRDESC_WSDService ws = new Z_MATRDESC_WSDServiceImpl();
          Z_MATRDESC_WSD port = (Z_MATRDESC_WSD)ws.getLogicalPort("Z_MATRDESC_WSDSoapBinding",Z_MATRDESC_WSD.class);
          String res = port.zXiTestGetMatrDesc("ABCD134");
          System.out.print(res);
The result I am getting is :
Warning ! Protocol Implementation [com.sap.engine.services.webservices.jaxrpc.wsdl2java.features.builtin.MessageIdProtocol] could not be loaded (NoClassDefFoundError) !
Error Message is :com/sap/guid/GUIDGeneratorFactory
<b>Material Not Found</b> -
> This is the output of webservice method and it is right.
Can any one please let me know why I am getting the warning and error message and how can I fix this.
Thanks
Abinash

Hi Abinash,
I have the same problem. Have you solve that problem?
I am using a java program to call a webservice too. And I have generated the client proxy definition for Stand alone proxy using NWDS. When I call the method of the webservice I am getting the correct result but along with the result I am getting one error and one warning message in the output.
The java code to call the webservice is as follows.
MIDadosPessoaisSyncService service = new MIDadosPessoaisSyncServiceImpl();
MIDadosPessoaisSync port = service.getLogicalPort("MIDadosPessoaisSyncPort");
port._setProperty("javax.xml.rpc.security.auth.username","xpto");
port._setProperty("javax.xml.rpc.security.auth.password","xpto");
String out = port.MIDadosPessoaisSync("xpto", "xpto");
System.out.println(out);
The result I am getting is :
Warning ! Protocol Implementation [com.sap.engine.services.webservices.jaxrpc.wsdl2java.features.builtin.MessageIdProtocol] could not be loaded (NoClassDefFoundError) !
Error Message is :com/sap/guid/GUIDGeneratorFactory
<b>The result of the WS is correct!!!</b>
The Java project does not have any warning. But the stand alone proxy project has following warnings associated with it.
This method has a constructor name     MIDadosPessoaisSync.java
The import javax.xml.rpc.holders is never used     MIDadosPessoaisSyncBindingStub.java
The import javax.xml.rpc.encoding is never used     MIDadosPessoaisSyncBindingStub.java
The constructor BaseRuntimeException(ResourceAccessor, String, Throwable) is deprecated     MIDadosPessoaisSyncBindingStub.java
It is very similar with your problem, could you help me?
Thanks

Problems running a java program

Hello,
I have absolutely no java experience whatsoever, and I need to fix a program that suddenly stopped running properly after several years without problems. Basically, I have a perl script that calls a java program. Everytime I run this perl script from the web browser, the java program returns an internal error:
# # HotSpot Virtual Machine Error, Internal Error # Please report this error at # http://www.blackdown.org/cgi-bin/jdk # # Error ID: 5649525455414C53504143450E4350500024 # # Problematic Thread: prio=5 tid=0x804e680 nid=0x6d16 runnable #
However, when I run the perl script command line, it runs fine. I added the -verbose option to the java call, and I discovered that the program stops running after it opens the .jar files but before it loads them .... these files have full read permissions, so I don't think that's the problem. Any ideas?
Thanks!

...fix a program that suddenly stopped running properly after several years without problems.Which means either the program changed or the environment changed. I would guess the environment. The most likely possibilities: new version of the operating system, new version of perl, new version of java. Also possible: new version installed of any of the previous without removing older versions, new software not associated with the first, new mapped drives and/or changed env vars.

picklistBC.release();
try
if(m_dataBean!=null)

Can any body please help us.
Thanks

From the error code, it looks like you have a scripting error in the BusComp_SetFieldValue event on the Position
business component in your application.
Have you tried to look at that code or to turn of scripting for the application as a total?

Problems with JAVA SE 6 in 1 Program.

Hello, I'm a new guy here, so sorry for mistakes
Problem that JAVA seems does not work propertly. This is the text from error.log in program that I want to start: "1020=The JVM found at {0} is damaged.\r\nPlease reinstall or define EXE4JJAVAHOME\r\nto point to an installed 32-bit JDK or JRE.". Cause I am not a pro in using mac os I can't understand how to solve this problem. Thank you for your time and answers.
