JavaMail classpath problems...

Hi there,
I have coded a function that will send an email. The code compiles perfectly in the command line and i have the mail.jar file placed in the C:\j2sdk1.4.2_12\lib\javamail-1.3 folder and the activation.jar file placed in the C:\j2sdk1.4.2_12\lib\jaf-1.0.2 folder with the classpaths set in the environment variables. Everytime i go to run the program i get the "java.lang.NoClassDefFoundError: javax/mail/Session" error in the console. It clearly can't find the Session.class for some reason. Anybody have any ideas what I can do to fix this?
(I have the jar files installed on the server that my application is located on)

Edited by: JamesAL on Jun 19, 2008 3:53 AM

I'm running it on a web server. It's part of an application on which orders can be placed. The email is basically a little confirmation email after the order is successfully placed. I have the classpath set for the neccessary jar files on the webserver in the Environment variables and also have the imports at the top. I am using JavaMail 1.3 and Java SDK 1.4 and it has been suggested there could be some sort of bug when trying to use this version of JavaMail with this version of Java. Do you think that is a possibility?
The function is located in the same .class file from which it is called (so its called internally) rather than it being located in the WEB-INF folder in tomcat. Would that make a difference?

Classpath problem

i am here stuck..
my dir structure is
c:\my\xxx\yyy\zzz
i have a code ...
package xxx.yyy.zzz;
class A
// some code
}i have compiled sucessfully and put the clsss file into c:\my\xxx\yyy\zzz folder.
now i want to import it in another class
like...
package xxx.yyy; // note this
import xxx.yyy.zzz.*; // note this
class B
// some code
// creating instance of class A here
}question is how do i compile and run it ?
i am at c:\my---> what should be the command to compile and run the above code?
plz give me the explicit command so that i can test and verify . i have given the dir structure.
i have tried several ways but got class not found exception and errors . i know its a classpath problem but i could not figure out what should i type at the c:\my prompt.
can u give exact command to run and compile the above code in steps ?
thanx

question is how do i compile and run it ?You don't with that code. You've defined class A to have "package visibility," meaning it can't be used from outside its package. You should declare it with public visibility instead, like "public class A {...".
Once you change that, use these commands to compile and run:c:\my\>javac xxx/yyy/zzz/A.java
c:\my\>javac xxx/yyy/B.java
c:\my\>java xxx.yyy.B

Classpath Problem (Using JSAPI)

Hi,
I using IBM Via Voice as a the implementation of the JSAPI on my system. I've downloaded the speech for java pack from IBM Alphaworks and put it in the directory of
c:\ibmjs
This gives you access to the speech packages for utilisation in your programs so I should be able to import javax.speech in my programs. However the system doesn't see these classes.
Heres my Autoexec...
path=%path%;c:\jdk1.3.1_01\bin;c:\ibmjs\lib;
CLASSPATH=%CLASSPATH%;c:\ibmjs\lib\ibmjs.jar;
I presume the whole thing is just a classpath problem, does anybody have any idea from the above paths where I am going wrong?

i guess you have to put some of ibm's dll files coming with speech for java in the path (not classpath). it's not sufficient to have the directories in the path.
anyway, there come's an installation manual with speech for java which explaines all that.

Fragment Bundle Classpath problems

Does anyone have any tips for solving classpath problems in fragment bundles? I'm getting a no-class-def that I can't explain.
I've used maven to create a fragment, hosted by com.day.crx.sling.server, to create a custom login. It needs to call a web service, so I've included httpclient-4.2.3.jar. I can see this jar listed on the deployed fragment's Bundle-ClassPath, via the osgi>bundle console. When I inspect the bundle that maven created, I can find this jar contained in the bundle jar, in the directory specified in the Bundle-ClassPath. I even oppened the httpclient jar to ensure that the offending class (org/apache/http/client/HttpClient) is there.
This is the first fragment that I've tried to build. Is there something I don't know about how they load classes?
Does anyone have any tips or tricks on solving osgi classpath problems? I read that felix has some tools, but I haven't found any documentation about them.

I'm still not sure why the classes didn't load, but I have a solution to my problem - don't try to include the jars in the fragment bundle. I tracked down osgi-ready versions of the libraries that I needed and and installed them.

Another simple classpath problem question

Hi All
Yes I know, there are a lots of questions about this matter, but I couldn't found a solution to my problem.
I have a simple program:
public class prueba {
public static void main(String[] args) {
System.out.println("Ahi va...");
}placed in /tmp/javier/prueba.java
After compiled, I've tried to run it from / and then problems started:
cd /
java /tmp/javier/prueba
Exception in thread "main" java.lang.NoClassDefFoundError: /tmp/javier/prueba (wrong name: prueba)
I said, ok...it could be a classpath problem...then:
java -cp /tmp/javier/ /tmp/javier/prueba
Exception in thread "main" java.lang.NoClassDefFoundError: /tmp/javier/prueba
Damn, another try...
java -cp .:/tmp/javier/ /tmp/javier/prueba
Exception in thread "main" java.lang.NoClassDefFoundError: /tmp/javier/prueba (wrong name: prueba)
Jesus Christ....may be the last slash....
java -cp .:/tmp/javier /tmp/javier/prueba
Exception in thread "main" java.lang.NoClassDefFoundError: /tmp/javier/prueba (wrong name: prueba)
Oh...no.... may be classpath to java classes..
java -cp .:/usr/java/j2sdk1.4.2_01/lib/jre/:/tmp/javier/ /tmp/javier/prueba
Exception in thread "main" java.lang.NoClassDefFoundError: /tmp/javier/prueba (wrong name: prueba)
Well, I don't know why this error happens....
Please, could somebody help me !!!
Thanks in advance...

It's not too early to start following the Sun coding
conventions for Java:
http://java.sun.com/docs/codeconv/html/CodeConvTOC.doc.
tmlHi
thanks for your reply.
Yes, I agree. I use conventions with my programs. But my real problem was with a real application and then I did quickly this simple code to help others to understand the problem and give a fast reply...
Let me know if that works. (It was fine on my
machine.) - MODYes it works fine, thanks.... and Damn...Murphys law again, the only option I didn't tried is the solution to my problem... :)
Thanks again...

Classpath problems in EAR packaging?

I try to access an EJB from a JSP. The JSP resides in web.war and the bean is in ejb.jar, and both of these are packaged together in an ear.
I get a compile error when I try opening a JSP. I've had this problem in all my attempts to use my bean classes from JSP.
My browser reports that the compiler cannot find the beans package. I have servlets within the war-file that are able to find the beans package, but the JSPs aren't.
My ear-file contains 3 files
ejb.jar
web.war
META-INF\MANIFEST.MF
The manifest classpath points to ejb.jar and web.war
My guess is that this has something to do with the way this is deployed by GlassFish.
The application is deployed in the
domains\mydomain\applications\j2ee-apps\myear\
This directory contains the expanded files:
ejb_jar\
web_war\
META-INF
So the Java classes under web_war\ are able to see the Java classes under ejb_jar\ (i.e. my servlets)
However; when GlassFish creates Java files from the JSPs and then tries to compile them, these files are placed under
domains\mydomain\generated\jsp\j2ee-apps\myear\web_war\org\apache\jsp\jsp
This might be correct for all I know, but apparently the compiler is unable to find the Java classes located under the mydomain\applications\.. directory when compiling classes located under the mydomain\generated\.. directory. There are no other files from my ear anywhere in the "generated" directory.
So to me this seems to be some kind of classpath problem, as the compiler cannot find the needed files.
Does this make any sense to anyone?
PS
In my ear, the JSPs are placed in the web.war. The war file looks like this:
jsp\
   myjsp.jsp
META-INF
   MANIFEST.MF
WEB-INF
   web.xml
   lib\
      mylib.jarThanks
\\Marius

Marius,
If you want communicate the bean you have to do following things.
. Create a factory for the correct protocol
. Obtain a Home
. Use the Home to create stubs to the remote object
So you want to call the Home and Remote interfaces to access the bean. When you run the client program, it will create the remote object that time it has to search the Home and Remote interfaces. So you have included those files for references in following location
WEB-INF/classes
     -- <Home Interface File Name>.class
     -- <Remote Interface File Name>.class
Or
WEB-INF/lib
     -- <Bean Jar file name>.jar
I think you will understand.

Again classpath problem

again classpath problem.... i have tried to solve it in many ways but all failed. here is one
instance of my effort which did not give me success.
i have a FOLDER > c:/com/abc/def/ijk
and files......
MyClass.java
==============
package com.abc.def.ijk
class MyClass
// blah
// blah
}c:\com\abc\def\ijk>javac MyClass.java ===>compiled fine and created a class file.
and also one more file.....
OneMoreClass.java
=================
import com.abc.def.ijk.MyClass
class OneMoreClass
// blah
// blah
}c:\com\abc\def\ijk>javac OneMoreClass.java ===> Error!!! package com.abc.def.ijk does not exist !!!!
how can i solve it ?

yea, this works....eariler i also usued to do this
way. but this time i forgot.
by the way, why individually it did not work !!!.Because you were in the package directory itself, and the classpath was set to the cwd, so java was looking for package directories at this level.
and also when i specify directly by
c:\com\abc\def\ijk
javac -classpath c:\com\abc\def\ijk\MyClass
OneMoreClass.java ...it does not work!!.
STRANGE! why ?Because by stating the package directory as classpath, you do the same as explained above. Stay out of package directories, stay one level above them, don't regard them as common directories. When declaring classpaths, don't mention package directories but the directories that contain them.

JDBC and Classpath problems on OpenVMS

Hello,
I'm working on an OpenVMS server and I got a simpler Java application that needs to establish a connection to an Oracle database, the application works perfectly well on Windows but when I moved to OpenVMS I got some problems with the oracle driver.
I believe I�m using the correct driver, I already checked on the oracle site according to my java version (1.4.2) and my database version (oracle 9i 9.2.0.7.0)
This is the error:
$java -jar miss.jar "DnBProcess"
About to start loading parameters for the MISS Proxy.
Successfully load parameters for the MISS Proxy.
About to load interface settings for DnBProcess
Settings for DnBProcess succesffully loaded.
About to load interface DnBProcess

at miss.DnBProcess.Execute(DnBProcess.java:178)
at miss.Proxy.ExecuteInterface(Proxy.java:160)
at miss.Proxy.main(Proxy.java:207)
I know is a classpath problem, and my classpath on VMS looks like this:
define JAVA$CLASSPATH .,SYS$COMMON:[JAVA$142.LIB]TOOLS.JAR,SYS$COMMON:[JAVA$142.LIB]DT.JAR,SYS$COMMON:[JAVA$142.JRE.LIB]RT.JAR, USER1:[MONTEALEGRE.TEST.LIBS]OJDBC14.JAR,USER1:[MONTEALEGRE.TEST.MISS.LIBS]OJDBC14.JAR,[]
As you can see I added the �ojdbc14.jar� in different folders but my application seems not to find it.
Does anyone know how to set the classpath properly on VMS? Or maybe give me some tips that could lead me to find a solution to this problem.
Thanks.
Ileana.

I would try googling for OpenVMS classpath. Unfortunatley the first result is this thread but there are a bunch of resources from IBM and HP listed and maybe they can help you.

Servicegen classpath problem

I'm trying to find out the status of the servicegen classloading problem
(specifying a classpath in a servicegen task causes class cast exceptions).
We are currently using the workaround described in this group which is
putting the weblogic jars in the system classpath. This workaround is very
unwieldy in our build environment. Is there any estimate on when the
problem will be fixed?

And was it? I am using 7.0sp4 and am getting classpath problems in servicegen.
The problem I am having is that the type generation fails to find any of the weblogic
utility classes, sug as weblogic.xml.schema.binding.util.runtime.PropertyInfo
(and many many others)

JavaMail Installation Problem-Further Help Required

Hi everyone, I am trying to install and configure JavaMail API and java activation framework so that I may start to try and write a Java Mail application, the problem I am having is that I am unable to get the sample program to work, I am compiling the sample program msgsend.java but I keep getting the following errors (I am using Jbuilder 2):

I have installed JavaMail and java activation framework into the following directories on my hard dirive:
JavaMail: C:\jdk1.3.1\lib\javamail-1.2
java activation framework : C:\jdk1.3.1\lib\jaf-1.0.1
My CLASSPATH is set to
C:\jdk1.3.1\lib\javamail-1.2;C:\jdk1.3.1\lib\jaf-1.0.1
I think that I have set this correctly, If not could somenone tell me what the CLASSPATH should be.
If I have set it correctly, could anyone tell me another reason why I cannot run the sample programand tell me how I may be able to fix it.
I have done a search on my computer for a file named javax\mail but it just says that javax is not a valid folder.
Any help would be appreciated
Thank You
Noel

>
Noel, I have said it twice now... your classpath is
supposed to be:
C:\jdk1.3.1\lib\javamail-1.2\mail.jar;C:\jdk1.3.1\lib\j
f-1.0.1\activation.jar
/MichaelI have set the classpath to what you suggested but when I compile the msgsend.java sample I am still getting the same errors as before, the folder where javamail and JavaBeansTM Activation Framework are still in the same location also (C:\jdk1.3.1\lib\javamail-1.2 & C:\jdk1.3.1\lib\jaf-1.0.1).
Can you tell me what is wrong?
Thanks

JavaMail Classpath

Good Day!
My JavaMail Codes were not able to be compiled. I feel that the Classpath MAY be wrong or I may not be following the correct steps involved to do that.
Can someone kindly help me to examine this classpath which I used but was not able to compile it:
set classpath=c:\Sun\AppServer\lib\mail.jar%classpath%;
set classpath=c:\Sun\AppServer\lib\activation.jar%classpath%;
NB: "javac is not recognised as an internal or external command, operable command or batch file" was the message on the command prompt screen.
pls I need more explanation
Thanks
Alam Winner

It's not your CLASSPATH setting, it's your PATH setting that's the problem.
PATH needs to be set to include the "bin" directory of your JDK installation
so the shell can find the "javac" command.

Jar file and classpath problem

I0m writing a program that use the kunststoff.jar Look&Feel.
Now I would like to put all I'm writing into a jar file but I always have a NoClassFoundException when I try to start my application.
here is a MANIFEST:ME I'm using:
Manifest-Version: 1.0
Created-By: 1.4.2-beta (Sun Microsystems Inc.)
Main-Class: JListaR.JListaR
Class-Path: kunststoff.jar img\ .why this don't work?

Unfortunately you can't embed jars within a jar and
expect them to be referencable for the classpath from
outside the main jar. The "Class-Path" attribute in
the manifest is used to refer to other jar files
outside of your jar file.
The usual approach to solve this problem is to unpack
the jar files you want to embed and then rejar
everything together in one big jar file again. This
isn't always a great approach though, I know I'm
looking for an alternative. So far my only alternative
is dynamic class loading using a classloader, however
this isn't great if you need to refer to several
hundreds or even thousands of classes.thank you very mach...now I understand because it dosen't work correctly!

Javac classpath problem

I get this error when trying to compile a simple program:
# javac -classpath .;/mnt/bdrive/MyData.class Test.java
javac: no source files
Usage: javac <options> <source files>
where possible options include:
***snip***
bash: /mnt/bdrive/MyData.class: Permission denied
It seems to be a problem with specifying more than one thing for the classpath. If I remove the ".;", it works. (I don't need the . in the classpath but I should be able to specify it)

probably :)
I originally had just the path and was trying it different ways. If I use just the path instead of the permission denied message, I get this:
bash: /mnt/bdrive/: is a directory
