Exception in thread "main" java.util.zip.ZipException:

Alright I've built an application using Sun Studio 8.1. This is a stand-alone application not web based. I've successfully added drivers that I need to run the app (classes12.jar) and have incorporated packaging ect. ect.

The application runs fine from the IDE, however when I go to the command line and into the <dist> folder where the jar file has been built/placed and try to execute the java -jar CANS_Email command I receive the following error:

Exception in thread "main" java.util.zip.ZipException: The system cannot find the file specified

at java.util.zip.ZipFile.open(Native Method)

at java.util.zip.ZipFile.<init>(ZipFile.java:110)

at java.util.jar.JarFile.<init>(JarFile.java:115)

at java.util.jar.JarFile.<init>(JarFile.java:57)

I can't understand what could be wrong when the readme.txt file from the build advises me to do the following:

========================

BUILD OUTPUT DESCRIPTION

========================

When you build an Java application project that has a main class, the IDE automatically copies all of the JAR files on the projects classpath to your projects dist/lib folder. The IDE also adds each of the JAR files to the Class-Path element in the application JAR files manifest file (MANIFEST.MF).

To run the project from the command line, go to the dist folder and

type the following:

java -jar "CANS_Email.jar"

To distribute this project, zip up the dist folder (including the lib folder)

and distribute the ZIP file.

Notes:

* If two JAR files on the project classpath have the same name, only the first JAR file is copied to the lib folder. * If the classpath contains a folder of classes or resources, none of the classpath elements are copied to the dist folder. * If a library on the projects classpath also has a Class-Path element specified in the manifest,the content of the Class-Path element has to be on the projects runtime path.

* To set a main class in a standard Java project, right-click the project node in the Projects window and choose Properties. Then click Run and enter the class name in the Main Class field. Alternatively, you can manually type the class name in the manifest Main-Class element.

Finally the manifest file looks like this:

Manifest-Version: 1.0

Ant-Version: Apache Ant 1.6.5

Created-By: 1.5.0_09-b03 (Sun Microsystems Inc.)

Main-Class: cans_email.MainForm

Class-Path: lib/swing-layout-1.0.jar lib/classes12.jar lib/src.zip

X-COMMENT: Main-Class will be added automatically by build

my lib folder has the following:

classes12.jar

src.zip

swing-layout-1.0.jar

thank you in advance.

- Can u go to 'dist' folder and try 'java -cp ./CANS_Email.jar .... <mainclassname>" ? In other words try and see if it works with the standard 'java' command instead of executing from the jar as in 'java -jar'...

- There is a src.zip in the classpath which may not be needed... of course, this is likely not the problem..

- Is your app using javamail? If so, it will need mail.jar and activation.jar files in the classpath.

http://java.sun.com/products/javamail/downloads/index.html

These are available in the ide so the program would work fine in the ide.

I did try the java -cp./CANS_Email.jar MainForm from the command line and received a Class def not found error (I tried several times every which way but loose)

I just threw the scr.zip in the lib out of fustration. It's already in the classpath so that wasn't it.The mail.jar and activation.jar files are in the classpath as well.

Thank you for your response.... so what do you think?

Can u try 'java -verbose -jar ..." ?

Ref: http://java.sun.com/j2se/1.5.0/docs/tooldocs/windows/java.html

also, you may want to check that the jar filenames and classnames are specified with correct case; java is case-sensitive and on windows case is quite frequently a reason for this exception...

Ok I used -verbose and got a laundry list of errors. It seems that my system is using an Oracle version of Java instead of my Sun Studio 8.1 version. I read somewhere else that the error I listed above typically stems from trying to run a newer version of Java in an old JRE, which would make sense. I just recently installed Sun Studio 8.1 for the purpose of creating this application, however I believe that I still have old Java scource files installed and they are the ones being utilized instead of the newer version.

Some of the Errors when using java -verbose -jar CANS_Email:

Is the stack trace you posted the complete output? To my eye it seems a bit truncated since we can't see what called the JarFile consructor.

Can u try running the jar with a different jdk and see what the results are?Some known jdk issues: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5032358 http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4885817

OK I changed the working directory in the IDE for the jar file. IN Sun Studio 8.1 you right click the package folder and go to properties and under "run" you can select the main class and the working directory and then re-build the jar file. so now my working directory is correct (or at least I believe) because my new error is the following:

Exception in thread "main" java.lang.UnsupportedClassVersionError: cans_email/MainForm (Unsupported major.minor version 49.0)

I believe I'm gaining ground, when I tried executing bogus jar files like java -jar nosuchjar.jar I would receive the error I was struggling with at first:

Exception in thread "main" java.util.zip.ZipException: The system cannot find the file specified

So I must be improving because now I believe it's trying to read the correct jar. Can anyone help me with this new finding? THANKS A MILLION IN ADVANCE!!!

"Unsupported major.minor version 49.0" message usually indicates jdk incompatibility; that is a class file compiled with one jdk version is being run by another jdk version.

Are u running the ide with 1.5 or greater? In which case, the classes generated cannot be run using jdk1.4.

You can of course tell the 1.5 compiler to generate 1.4 compatible code and then you will be able to run that class with 1.4.

- Right-click on the project and select properties.

- Select 'sources' category in the properties dialog.

- Set the source level to "1.4"

- OK the dialog. Run 'clean and build'.

Ref: http://java.sun.com/j2se/1.5.0/docs/tooldocs/windows/javac.html#options ('-source' section).

GOT IT!!!! I installed the JRE 1.5 on a different machine and it worked on that PC. I have an Oracle Application Oracle Forms Builder on the PC that has the Sun Studio 8, and I can't seem to get the PC (the one with Studio 8) to use JRE 1.5 instead of the old 1.3 version. I'm going to have to do some configuring on that machine and see if I can fix it.

Thanks for all your help KarthikR!!!!
