Classpath is not identifing the class file

Iam developing cumtom java function event in Oracle WorkFlow. Here iam getting ClassNotFoundException. I included all class file in the jar file and the jar file added in the class path
The problem seems be, java compiler not recognising the class which is there in the classpath.. any one suggest on this. ??

Let's get this straight first: ClassNotFoundException is something that happens at runtime; that means you must have been able to compile your program successfully. So it is not the "java compiler not recognising the class".
What does your classpath look like exactly?
Is the class you are trying to use in a package?
Are you correctly importing the class?
Look inside the JAR files in your classpath to check if the class is really present in one of the JAR files.
If you were able to compile the code successfully but you get an error while running it, then the compiler must have been able to find the class while you were compiling it. Are you passing the same classpath to the Java runtime environment as what you are using when you were compiling your code?
And by the way, you posted this question in the forum about generics, but your question does not have anything to do with generics. Please post your questions in the appropriate forum in the future.

JNI generated header file does not match the class file

We have had a JNI project for many years and all has been fine. Within our libraries we have several classes that have inner enum classes.
Recently we have moved to JDK1.7. Up to now when JNI generated the methods where the signature used the inner enum class, and it was an oveloaded method, we would get something like the following as the signature:
Java_PackageName_ClassName_methodName_OuterClass_00024InnerEnum_2
And the class file result of the build would look like the following:
methodName(OuterClass$InnerEnum)
Since we have moved to JDK 1.7 the header file looks like the following:
Java_PackageName_ClassName_methodName_OuterClasss_InnerEnum_2
The class file is still the same, and because of that when we run the program we get an UnsatisfiedLinkError. I understand that this error is because the VM cannot find the implementation. So why JDK 1.7 generates a header file that does not match the class file?
Thank you in advance.

I don't have 1.6 to verify but your statements about what is generated for 1.7 for the header appear correct.
The 000024 represents the '$' and for 1.7 the inner class is still named using '$'. So for example after compiling in 1.7 the inner class file is named the following...
MyClass$InnerEnum.class
So a one to one conversion should have kept the 000024 (presuming it does in fact do it that way in 1.6.)
You might want to look at the release notes for 1.7.
If you need a solution you could add a post javah step that renames the file.

How to find the arguments of a static method from the class file

Hi,all !
How to find the arguments of a static method from the class file? for example, when we meet a bytecode "invokestatic", how can I know the arguments of this static method?

Hi,all !
How to find the arguments of a static method from the
class file? for example, when we meet a bytecode
"invokestatic", how can I know the arguments of this
static method?You mean
1. The values?
2. Argument names?
3. Argument signatures.
I would suppose for the last that the easiest way would be to parse the signature string.
The first is not possible - not from the class file.
The second is only in the debug information stored in the optional part of the class file. And figuring out the format for that is going to be a problem.

Java -jar Test.jar option is not identifing the CLASSPATH on UNIX BOX

Hi All,
java -jar Test.jar
I am trying to execute Test.jar file using -jar option. I am able to excute the Test.jar file but it is not identifing the CLASSPATH set for other JAR files which is used in part of Test.jar. Saying java.lang.NoClassDefFoundError: for the class which are set in CLASSPATH.
The same is able to identify the CLASSPATH if i excute the Test.class file directly with out -jar option like
java Test. In this case everything is working fine.
Can any one tell me why it is not identifying the classpath if i use or execute with java -jar Test.jar option.
Thanks,
sha

When you use the -jar option, the only classpath that is used is the Class-Path in the manifest file of the jar. If there is no Class-Path, then only the jar is searched for classes. If there is a Class-Path, the paths must be relative to the jar file.

Hi
Are you using wli process control?
That uses wsdl and could cause the issue.
I also saw couple of internal bugs CR264315 and CR288904 on the same issue on 9.2.
Since this is a wli issue could you post in the wli newsgroup to get more answers http://forums.bea.com/forum.jspa?forumID=2047 ?
Also you can open a BEA support case at http://support.bea.com and an wli support engineer would help you. Please refer to the Cr numbers above in your support case.

How do I make a batch file if the .class file uses a foreign package?

I am trying to make an MS-DOS batch file using the bytecode file from the Java source file, called AddFields.java. This program uses the package BreezySwing; which is not standard with the JDK. I had to download it seperately. I will come back to this batch file later.
But first, in order to prove the concept, I created a Java file called Soap.java in JCreator. It is a very simple GUI program that uses the javax.swing package; which does come with the JDK. The JDK is currently stored in the following directory: C:\Program Files\Java\jdk1.6.0_07. I have the PATH environment variable set to the 'bin' folder of the JDK. I believe that it is important that this variable stay this way because C:\Program Files\Java\jdk1.6.0_07\bin is where the file 'java.exe' and 'javac.exe' are stored. Here is my batch file so far for Soap:
@echo off
cd \acorn
set path=C:\Program Files\Java\jdk1.6.0_07\bin
set classpath=.
java Soap
pause
Before I ran this file, I compiled Soap.java in my IDE and then ran it successfully. Then I moved the .class file to the directory C:\acorn. I put NOTHING ELSE in this folder. then I told the computer where to find the file 'java.exe' which I know is needed for execution of the .class file. I put the above text in Notepad and then saved it as Soap.bat onto my desktop. When I double click on it, the command prompt comes up in a little green box for a few seconds, and then the GUI opens and says "It Works!". Now that I know the concept of batch files, I tried creating another one that used the BreezySwing package.
After I installed my JDK, I installed BreezySwing and TerminalIO which are two foreign packages that make building code much easier. I downloaded the .zip file from Lambert and Osborne called BreezySwingAndTerminalIO.zip. I extracted the files to the 'bin' folder of my JDK. Once I did this, and set the PATH environment variable to the 'bin' folder of my JDK, all BreezySwing and TerminalIO programs that I made worked. Now I wanted to make a batch file from the program AddFields.java. It is a GUI program that imports two packages, the traditional GUI javax.swing package and the foreign package BreezySwing. The user enters two numbers in two DoubleField objects and then selects one of four buttons; one for each arithmetic operation (add, subtract, multiply, or divide). Then the program displays the solution in a third DoubleField object. This program both compiles and runs successfully in JCreator. So, next I moved the .class file from the MyProjects folder that JCreator uses to C:\acorn. I put nothing else in this folder. The file Soap.class was still in there, but I did not think it would matter. Then I created the batch file:
@echo off
cd \acorn
set path=C:\Program Files\Java\jdk1.6.0_07\bin
set classpath=.
java AddFields
pause
As you can see, it is exactly the same as the one for Soap. I made this file in Notepad and called it AddFields.bat. Upon double clicking on the file, I got this error message from command prompt:

Press any key to continue . . .
I know that most of this makes no sense; but that it only means that it cannot find the class BreezySwing or GBFrame (which AddFields extends). Notice, however that it does not give an error for javax.swing. If I change the "set path..." command to anything other than the 'bin' folder of my JDK, I get this error:
'java' is not recognized as an internal or external command,
operable program or batch file.
Press any key to continue . . .
I know this means that the computer cannot find the file 'java.exe' which I believe holds all of the java.x.y.z style packages (native packages); but not BreezySwing or any other foreign packages. Remember, I do not get this error for any of the native Java packages. I decided to compare the java.x.y.z packages with BreezySwing:
I see that all of the native packages are not actually visible in the JDK's bin folder. I think that they are all stored in one of the .exe files in there because there are no .class files in the JDK's bin folder.
However, BreezySwing is different, there is no such file called "BreezySwing.exe"; there are just about 20 .class files all with names like "GBFrame.class", and "GBActionListener.class". As a last effort, I moved all of these .class files directly into the bin folder (they were originally in a seperate folder called BreezySwingAndTerminalIO). This did nothing; even with all of the files in the same folder as java.exe.
So my question is: What do I need to do to get the BreezySwing package recognized on my computer? Is there possibly a download for a file called "BreezySwing.exe" somewhere that would be similar to "java.exe" and contain all of the BreezySwing packages?

There is a lot of detail in your posts. I won't properly quote everything you put (too laborious). Instead I'll just put your words inside quotes (").
"..there are some things about the interface that I do not like."
Like +what?+ This is not a help desk, and I would appreciate you participating in this discussion by providing details of what it is about the 'interface' of webstart that you 'do not like'. They are probably misunderstandings on your part.
"Some of the .jar files I made were so dangerously corrupt, that I had to restart my computer before I could delete them."
Corrupt?! I have never once had the Java tools produce a corrupt Jar. OTOH, the 'cannot delete' problem might relate to the JRE gaining a file lock on the archive at run-time. If the file lock persisted after ending the app., it suggests that the JRE was not properly shut down. This is a bug in the code and should be fixed. Deploying as .class files will only 'hide' the problem (from casual inspection - though the Task Manager should show the orphaned 'java' process).
"I then turned to batch files for their simple structure and portability (I managed to successfully transport a java.util containing batch file from my computer to another). This was what I did:
- I created a folder called Task
- Then I copied three things into this folder: 1. The file "java.exe" from my JDK. 2. The program's .class file (Count.class). and 3. The original batch file.
- Then I moved the folder from a removable disk to the second computer's C drive (C:\Task).
- Last, I changed the code in the batch file...:"
That is the +funniest+ thing I've heard on the forums in the last 72 hours. You say that is easy?! Some points.
- editing batch files is not scalable to 100+ machines, let alone 10000+.
- The fact that Java worked on the target machine was because it was +already installed.+ Dragging the 'java.exe' onto a Windows PC which has no Java will not magically make it 'Java enabled'.
And speaking of Java on the client machine. Webstart has in-built mechanisms to ensure that the end user has the minimum required Java version to run the app. - we can also use the [deployJava.js|http://java.sun.com/javase/6/docs/technotes/guides/jweb/deployment_advice.html#deplToolkit] on the original web page, to check for minimum Java before it puts the link to download/install the app. - if the user does not have the required Java, the script should guide them through installing it.
Those nice features in deployJava.js are available to applets and apps. launched using webstart, but they are not available for (plain) Jar's or loose class files. So if 'ensuring the user has Java' is one of the requirements for your launch, you are barking up the wrong tree by deploying loose class files.
Note also that if you abandon webstart, but have your app. set up to work from a Jar, the installation process would be similar to above (though it would not need a .bat file, or editing it). This basic strategy is one way that I provide [Appleteer (as a downloadable ZIP archive)|http://pscode.org/appleteer/#download]. Though I side-step your part 1 by putting the stuff into a Jar with the path Appleteer/ - when the user expands the ZIP, the parts of the app. are already in the Appleteer directory.
Appleteer is also provided as a webstart launched application (and as an applet). Either of those are 'easier' to use than the downloadable ZIP, but I thought I would provide it in case the end user wants to save it to disk and transport the app. to a machine with no internet connection, but with Java (why they would be testing applets on a PC with no internet connection, I am not sure - but the option is there).
"I know that .jar and .exe files are out because I always get errors and I do not like their interfaces. "
What on earth are you talking about? Once the app. is on-screen, the end user would not be able to distinguish between
1) A Jar launched using a manifest.
2) A Jar launched using webstart.
3) Loose class files.
Your fixation on .bat files sounds much like the adage that 'If the only tool you have is a hammer, every job starts to look like a nail'.
Get over them, will you? +Using .bat files is not a practical way to provide a Java app. to the end user+ (and launching an app. from a .bat looks quite crappy and 'second hand' to +this+ user).
Edit 1:
The instructions for running Appleteer as a Jar are further up the page, in the [Running Appleteer: Application|http://pscode.org/appleteer/#application] section.

Hi Gowsika,
the class needed is located in htmlb.jar which can be found under <irj-root>/WEB-INF/portal/portalapps/com.sap.portal.htmlb/lib
You need to integrate this jar in your .classpath
Hope this helps,

Weblogic Server not picking the jar files in WEB-INF/lib folder

we are facing a strange problem where Weblogic App Server is not picking the jar files present inside the WEB-INF/lib folder if we update the jar file path in the classpath of the start script then the classes get loaded properly.
Is there any specific setting which I need to do in weblogic to pick these jars ?

Class loaders associated with a Web application can be configured to locate local classes first. To enable this we have to set the <prefer-web-inf-classes> to true in the deployment override weblogic.xml, for example
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
http://blog.transfer-solutions.com/2010/12/weblogic-class-loading/

Please,please help, this drives me crazy,can not find the class but...

The story is:
I have alot java class files under directory: c:\myproj\com\pin\sa
in each of the file, the package signature is: package com.pin.sa
Then I set the JavaVMInitArgs fVM_args; by setting the classpath to:c:\myproj
then I use: cls = (*fEnv).FindClass("com/pin/sa/frameWork") to find a class file called frameWork, but failed.
then i build a test file called test.class (it is just a simple file pls see below for the code)and put package com.pin.sa in it and put it in directory : c:\myproj\com\pin\sa, this means the test.class is under the same directory as the frameWork.class,
then I use cls = (*fEnv).FindClass("com/pin/sa/test"), and it SUCCEEDED!!!
I really don't understand why like this, they have same package signature and under same directory why different results.
In frameWork file, there are some imported packages, does this matter? And there is a static main() in it.
if you can give an example of how to set the classpath in JavaVMInitArgs fVM_args, and how to deal with the package signature, I will appreciate it very much
==test.java==
package com.pin.sa;
public class test
public void printHello()
System.out.println("Hello World from Java!");
cls = (*fEnv).FindClass("com/pin/sa/test");
cls = (*fEnv).FindClass("com/pin/sa/test");
C:\\myProj\\resiprocate\\myAnalysis\\sipphone\\sipXphone\\main\\softphone\\lib");

Hi Hufuman,
What are the packages that you are using in frameWork Class. Add the class path to those classes also. Also check the name of the .class file is exactly the same as frameWork and not FrameWork or framework etc.
Check whether you have correctly given the package declaration in the frameWork class.
If you dont have any problem, post the frameWork class definition also here or atleast the packages imported and the classpath set for those referred packages.

Advice on encrypting the class files so that it cannot be reverse engineer

Hi,
i will like to ask if there is any way where we can encrypt the class files so that people cannot use reverse engineering to modify the codes?

ThanksIn addition to what others said encryption is totally different from what you want.(called as 'obfuscation').Not necessarily. You could encrypt the class files, but then you would have to provide an unencrypted ClassLoader (and possibly Main if you didn't want to put the ClassLoader in the bootstrap classpath) that is capable of decrypting them. Then, someone could decompile this ClassLoader (obfuscated or not) and either simply take the decryption algorithm and decrypt the classes, or even easier, simply modify the ClassLoader to write out the decrypted class files itself.
So, why would you? ;-)

How to hide the source code from the .class file

Hi,
By some jad tool we can recompile the .class files and get the java file corresponding to it. How to protect it?
Anyone please help me..
Thanks & Regards,
N.Ravasankar

An obfuscator can for example rename classes, variables to meaningless names, like one-letter names. And it can make some bytecode that is hard to decompile or just makes the code less readable when decompiled. Some obfuscators might even be able to do something to the code that makes decompilers not work or incorrect decompile code.

This is the css file code that I like to apply to the show_email_entry.jsp
named: Displaydata.css
This rules are for background color for data display
/*td.column{
background-color: #f0f8ff;
background-color: #fffacd;
td.headerColumn{
background-color: #daa520;
font-weight: bold;
font-family: sans-serif,Verdana, Arial, Helvetica;
font-size: 10pt;
td.column{
font-family: sans-serif,Verdana, Arial, Helvetica;
font-size: 10pt;
white-space: nowrap;
background-color: #fffacd;
a{
text-decoration: none;
h1{
color: red;
They are working fine. However, it just does not execute the css file in the show_email_entry.jsp. Another word, the headerColumn should show some color as I coded it in the css file. But it shows only white background and black text. I have the file named DisplayData.css in the same directory as the file named show_email_entry.jsp. But it still does not work.
if I create a test.jsp and use with the DisplayData.css file above then it would work fine. But when I used it with the servlet file, then it would not work.
Anyone knows why ?
