Classpath and manifest.mf

what is the difference between classpath, buildpath and a Manifest.mf paths?
I believe class path is used at run time to look for the classes referred in this path.
Build path is used to build the application i.e. to link the components used while compiling and building classes.
Manifest.MF is also used for runtime resolution.
What different purpose did classpath and manifest.mf serve?

If I understand you correctly, this is more of a general Java Question then a Java Servlet Question... but anyway...
The manifest.mf is defined for JARs. Your system CLASSPATH, and the classpath set on the command line are ignored for JARs, and only the CLASSPATH set in the manifest is used.
When running applications outside of JARs, then the system/command line CLASSPATH is used.
When running a web application inside a WAR, the server has its own classpath which will override that of the manifest and the system CLASSPATH.

Classpath and property problem in services

Hi, all,
I've had a number of problems getting the Stockquote example to run properly. This seems to be due to a problem that services don't get either classpaths or properties when they start.
The first manifestation of this problem came when the proxySet, proxyHost, and proxyPort environment variables weren't getting set properly in class services.stockquote.Stockquote. The symptom was that url.openStream () timed out because the proxy was not set correctly.
The second symptom comes when"JavaPort" is used as the port on the client. Despite every attempt I've made to put services.stockquote.Stockquote on the classpath, URLClassLoader will not find this class. However, a call to Class.forName("services.stockquote.Stockquote") in Main.java, just before the bottom of the stack, works! It works in both the client and the server!
So, could someone please tell me why the classpath and properties are getting shucked, and how to get them right?
I'm on Windows 2000 :p using JDK 1.3.1 and Tomcat 4.0.
Thanks,
- Steve.

Vivek, I think this belongs in a different thread. Also you'll need to say what problems you're having.
The only thing that definitely needs to be changed about the example is that the service may fail if it's run behind a proxy server. You'll need to set the following System properties:
System.setProperty("proxySet", "true");
System.setProperty("proxyHost", "your.proxy.com");
System.setProperty("proxyPort", <your proxy port>");
If this isn't done you'll get an exception like the following:
Exception in thread "main" com.ibm.wsif.WSIFException: SOAP Fault:SOAP-ENV:Server Exception from service object: Operation timed out: connect
-S.

Classpath in manifest file

what is 'classpath' in manifest file used for?
I tried to create classpath, but doesnt have any significant different....
thanks
YAn

This is what the tutorial says about class-path in a manifest file:
Download extensions are JAR files that are referenced by the manifest files of other JAR files. See the trail on the extension mechanism for information about extensions.
     In a typical situation, an applet will be bundled in a JAR file whose manifest references a JAR file (or several JAR files) that will serve as an extension for the purposes of that applet. Extensions
     may reference each other in the same way.
     Download extensions are specified in the Class-Path header field in the manifest file of an applet, application, or another extension. A Class-Path header might look like this, for example:
          Class-Path: servlet.jar infobus.jar acme/beans.jar
     With this header, the classes in the files servlet.jar, infobus.jar, and acme/beans.jar will serve as extensions for purposes of the applet or application. The URLs in the Class-Path
     header are given relative to the URL of the JAR file of the applet or application. For more details, see the link shown below:
http://java.sun.com/docs/books/tutorial/jar/basics/manifest.html

J2EE Packaging and manifest Class-Path:

Does anyone know if Weblogic 6.0 supports the redefined deployment extension mechanism
that makes use of the 'Class-Path:' entry in the manifest files?
In our project we have one single .ear file containing a couple of EJB's (.jar
files) and a Web Application (.war file).
We are using log4j as logging mechanism and we would like to keep everything in
the .ear file so that we can make hot-deploys. So we are trying not to make use
of the classpath in startWebLogic.sh. All of our EJB's and the Web Application
makes use of log4j.jar. My question is; can I do the following and make it work
in Weblogic 6.0?
1. In every EJB .jar file I add the follwing to the manifest file - "Class-Path:
log4j.jar"
2. I place the log4j.jar in the root directory of the .ear file.
By doing this I expect that the ear classloader loads the log4j.jar classes. Am
I right or do I do something wrong. At least it does not seem to work.

Thanks,

This does not work in WebLogic 6.0. It's supposed to be supported in 6.1

Can I specify classpath in MANIFEST.MF of a ear file?

Hi,
I know that one can specify classpath in MANIFEST.MF of a jar file, I'd like to know whether I can specify classpath in MANIFEST.MF of a ear file?
If yes, will the classpath specified affect all j2ee components in this ear file?(e.g. jar files,war files)
Thanks

Unfortunately, yes, you'd have to edit the MANIFEST.MF
of each module within the .ear that has a dependency on
the bundled library. One workaround is to add the common
code to the server's classpath. However, that approach
doesn't work if the common code has dependencies on the
code packaged within the ejb-jars and .wars themselves.

WebLogic 11g EAR EJB Classpath and class loaders

All,
I have been having issues migrating Spring based EJB applications from OC4J to WebLogic 11g (10.3.1). I have been in communication with Oracle who has suggested a work around however I am keen to see if anyone else can suggest a solution.
The application is dependant on stateless session EJB beans that communicate with a Spring managed service tier to perform the business logic and database access. PitchFork is used to inject the Spring managers into the EJB’s using the spring-ejb-jar.xml configuration file. Note originally I was using the SpringBeanAutowiringInterceptor however I could not get this to work. See WebLogic 11g and Spring beens injected into EJB for details.
When the application is deployed packaging all the dependant jars within the APP-INF\lib folder I get a verity of errors from the following InvalidClassException, NoSuchMethodError, AbstractMethodError and IllegalArgumentException. I am using Spring 2.5.3 to match the supported WebLogic version. Note within the EAR application.xml the library-directory is set to APP-INF/lib. The issue appears to be Spring, PitchFork, commons-logging and aspectj libraries are being loaded form WebLogic and do not have visibility on jars within the application or have been modified when bundled for WebLogic. An example of this is the PitchFork jar within WebLogic has been changed excluding the spi package resulting in java.lang.ClassNotFoundException: org.springframework.jee.spi.PitchforkUtilsImpl errors.
Moving the jars to the domain library path does not resolve any of the issues. I have been unable to successfully deploy the application picking up the application jars using the prefer-application-packages configuration.
Oracle has advised me to deploy the libraries into the WebLogic system classpath by modifying the startWebLogic command to load the libraries into the classpath. I am concerned that modifying the system classpath will result in an unstable WebLogic server as I will be replacing modified jar files packages with WebLogic (such as PitchFork). This will also limit the applications that can be deployed within the server as each application must use the same libraries and versions (as the application ibraries are leing ignored).
Has anyone else hit this issue and corrected it? Can anyone think of an alternative solution?
Regards
Neil

Hi,
I am in the process of updating the tracking bug# 331569 with copies of the eclipse EAR/WAR projects and the EAR for these scenarios. Here are some details on how I got past the 2nd CCE on the org.eclipse.persistence.jpa.PersistenceProvider class (not the javax one)
https://bugs.eclipse.org/bugs/show_bug.cgi?id=331569
Essentially an SE persistence unit running both JPA 2.0 api and the 2.0 XSD schema work fine. I will next retest the EE case with variations of the 3 types of injection on the SSB or Servlet.
Update: There are 3 (possibly 4) issues here (all of these may become obsolete when the next WLS version ships)Initially I got the same 2.0 schema error and the ClassCastException on org.eclipse.persistence.jpa.PersistenceProvider
It turns out that my import of the 2 eclipse projects from my bug # 296271 for WebLogic 10.3.2.0 lost their facets(specifically the dynamic web facet) because I associated them with a different WebLogic 10.3.3.0. - this caused the CCE I was experiencing like Sri.
Anyways, after creating an EAR/Web project combination from scratch in eclipse associated with the 10.3.3.0 instance - I predeployed/deployed/ran fine - even with the 2.0 schema - in SE bootstrap mode (no EE yet).
Reproduction Procedure:
redoing project from scratch as I noticed that the war was not at the root of the ear - it was a jar in the app-inf/lib dir - my imported eclipse project was not referenced correctly as a web module facet- create empty EAR and WAR project with references
- download and open my EAR and WAR project code from bug # 296271
https://bugs.eclipse.org/bugs/show_bug.cgi?id=296271
- do essentially all the steps in the page below (I paraphrase for re-verification)
http://wiki.eclipse.org/EclipseLink/Development/JPA_2.0/weblogic#DI_1.1:_Alternative_3:_Application_Level_Shared_Library_-InUse
- copy applicationService, entity and FrontController servlet code into new projects
- create persistence.xml and MANIFEST.MF manifest in src\META-INF
- update manifest
Class-Path: APP-INF/lib/eclipselink.jar
APP-INF/lib/javax.persistence_2.0.0.v200911041116.jar
- copy both javax.persistence 2.0 and eclipselink 2.x jars to APP-INF/lib
- change ordering of WebLogic library modules classpath reference (javax.persistence 1.0) to ear reference (2.0 version)
- update web.xml with servlet tags
- update weblogic.xml with new context root
- make the persistence unit name the same in persistence.xml and ApplicationManagedService
- update weblogic-application.xml with prefer-application-packages overrides
<wls:prefer-application-packages>
<wls:package-name>javax.persistence.*</wls:package-name>
<wls:package-name>org.eclipse.persistence.*</wls:package-name>
</wls:prefer-application-packages>
- enable server redirect logging

<property name="eclipselink.logging.logger" value="DefaultLogger"/>
- start WebLogic 10.3.3.0
- deploy (run on) server from eclipse or export ear to auto deploy directory
1) JPA 2.0 XSD usage on 10.3.3.0
- I reproduced this issue with a bad EAR
- was able to use the 2.0 schema within the WAR-only application managed EAR

2) CCE on JPA provider implementation class
Error instantiating the Persistence Provider class org.eclipse.persistence.jpa.PersistenceProvider of the PersistenceUnit example2: java.lang.ClassCastException: org.eclipse.persistence.jpa.PersistenceProvider
- I reproduced and fixed this one (was Eclipse project facet issue) - EAR was wrong
- was able to run JPA 2.0 code fine on an SE PU (predeploy/deploy together)
- EE injection should not work but I will post an example EAR anyway
log[EL Example]: enterprise: JPA 2.0 Metamodel: MetamodelImpl@56287508 [ 3 Types: , 1 ManagedTypes: , 1 EntityTypes: , 0 MappedSuperclassTypes: , 0 EmbeddableTypes: ]
3) CCE on JPA spec interface class
- I could not reproduce this one
Re: WebLogic 11g EAR EJB Classpath and class loaders
Error processing persistence unit PT of module pt: Error instantiating the Persistence Provider class org.eclipse.persistence.jpa.PersistenceProvider of the PersistenceUnit PT: java.lang.ClassCastException: org.eclipse.persistence.jpa.PersistenceProvider cannot be cast to javax.persistence.spi.PersistenceProvider
4) CCE on fallback Kodo JPA provider (if an invalid say 2.1 JPA XSD schema is referenced)
java.lang.ClassCastException: kodo.persistence.PersistenceProviderImpl
at javax.persistence.Persistence.findAllProviders(Persistence.java:186)
java.lang.NoSuchMethodError: javax/persistence/EntityManager.getMetamodel()Ljavax/persistence/metamodel/Metamodel;
- reproduced by using the 1.0 javax.persistence jar (but named as the 2.0 one in APP-INF/lib)
- fixed by using either the 1.0 or 2.0 JPA XSD schema and using the correct 2.0 spec jar

Classpath and hash Character (#)

Hi,
I have some jar files in my java classpath and it looks as if the JVM does not manage to find them when the jar file path contains a hash character (#) (java.lang.NoClassDefFoundError Exception is raised)
I haven't found anything about this in docs.
Can anyone help me ?
Thanks
Michel

Maybe not.
However, once I do not need these classes which are stored in a file path with a hash character, everything works fine.
You can experiment by yourself following this basic scenario:
1) store your famous HelloWord.class in a directory containing a hash Character (e.g. C:\tmp\te#st )
2) run your jvm as follows: java -classpath C:\tmp\te#st HelloWord
3) you should see the message
"Exception in thread "main" java.lang.NoClassDefFoundError: HelloWorld"
if not, tell me. I am completely wrong.
PS: Enviromment: WindowNT, sdk 1.4.0 or sdk 1.3.1

I must confess that I am totally unable to understand what your PATH is set to. The error that you see,
<'javac' is not recognized as an internal or external command,operable program or batch file.>
is due to a missing or incorrectly set PATH. It is used by Windows to find executable file (like javac.exe) that you have added to the computer. Item #5 on this page gives you instructions on how to set it: http://java.sun.com/j2se/1.4.2/install-windows.html
As for the setting of the CLASSPATH, you seem to have a number of different versions of java (1.4.2_02, 1.4.2_01, 1.4.2_2, and 1.1.8) and I doubt that these are all valid. You are also using an unusual syntax C:\java_home\jdk1.4.2_2\bin\javadoc Fruit.java and I wonder if that is really C:\java_home\jdk1.4.2_2\bin\javadoc\Fruit.java? I think the best action is to point you to Sun's instructions and information about setting and using the CLASSPATH.
The CLASSPATH is a set of pointers that is used by Java to find the files that YOU (not Java) create and want compiled and/or run.
Setting the Classpath:
http://java.sun.com/j2se/1.4.2/docs/tooldocs/windows/classpath.html
[NOTE: always start your classpath with ".;" which means the current directory. See my classpath, below]

http://java.sun.com/j2se/1.4.2/docs/tooldocs/findingclasses.html

Creating & Using .jar files and manifests

I've read through hundreds of online tutorials on creating and using .jar's, but it's surprising how unhelpful they really are.
I've been trying to make a java program of mine standalone, so I can distribute it to others and allow them to run it without use of a compiler, etc (ideally just a .exe or .bat that they double click on). Everything I've found says I need to create a .jar of my program in order to do this. I was finally able to create a .jar but I got different errors relating to "main-class" and "manifest" issues...I tried running it with javaw.exe and had the same problem.
Some tutorials briefly discuss "meta manifest's", other's skip the concept all together in creating .jar's. I created a jar with:
jar cf A2.jar c:\jarTester.java
after changing my command prompt path to
C:\Program Files\Java\jdk1.6.0_01\bin
It created the .jar, but nothing worked. As above, it gave me errors relating to the "Main-Class" and "Manifest". So here's my question:
What involvement does a "manifest" play in .jar's, and how do I create/use one to create a .jar? Why is it necessary to specify the "Main-Class" when I have already done so in my .java file?
I believe that once I can get this "Main-Class" and "Manifest" problem straightened out, I will be able to create a batch file with the line:
java -jar A2.jar
is this correct? THANKS.

Hi Satosh Sutar,
Based on the description, you got the error message when you update the apps from version 1.0 to 1.1.
From the error message, it seems the menifest include some settings no allowed in the new version. Would you mind sharing more detail about how you update the project?

Custom classpath and custom jar entry in R12

Hi all,
I have created the custom classpath and custom jar file for isrore process. I had put custom jar and custom class entry in orien_application.xml file. But it was working on R12 at doveloper mode. It will creates the classes for custom jsp file using custom import class or custom jar. But once i revert back the devloper mode means it won't work.
Could you please help..

Oracle apps R12 - Compiling JSP with custom classpath
We all know that to compile JSP manually on the Oracle Application R12 instance, we need to run the file $FND_TOP/patch/115/bin/ojspCompile.pl.
Its help is as follows:
syntax: ./ojspCompile.pl COMMAND {ARGS}
COMMAND --compile               update dependency, compile delta
--create                rebuild entire dependency file
-delta.out update dependency, list delta to file
-dep.out update dependency, output heirarchy to file
ARGS -s matching condition for JSPs filenames
-p number of parallel compilations
-log to override logfile from ojspCompile.conf
You are
recommended to set the log file location
outside of any network file system shared (NFS) area/drive.
-conf to override ojspCompile.conf
--retry         retry previously failed compilation attempts
--flush         forces recompilation of all parent JSPs
--quiet         do not provide an actively running progress meter
--fast          instantly fail jsps that are possibly invalid
example1: ojspCompile.pl compile -s 'jtf%' -p 20 retry
example2: ojspCompile.pl compile -s 'jtflogin.jsp,jtfavald.jsp' flush
example3: ojspCompile.pl compile fast --quiet
If your JSP uses custom classes, then compiling jsp manually can fail if proper classpath is not set. Yes, even though if you have setup the classpath correctly in orion-application.xml, it will fail because this jsp compile utility does not read orion-application.xml classpath.
So, the problem is to identify where to set the classpath so that above utility can pick it up. After several search and looking into code, I found following:
By default, the jsp compiler script uses following configuration file
$INST_TOP/appl/admin/ojspCompile.conf
This conf file has a classpath field in it which is usually pointed to file
$INST_TOP/appl/admin/ojspCompile.properties
This property file lists the classpath used for JSP compilation.
So if your classes are not listed in this file, your jsps will not compile by ojspCompile.
Ofcourse, you can always set the "main_mode" to "recompile" in orion-web.xml, but that for production you do not want to change it and compile the JSP on file deployment.

CLASSPATH and JAVA_HOME commands (variables) aren't recognized by DOS

My command prompt doesn't recognize neither CLASSPATH nor JAVA_HOME commands...I've already set the path variable "C:\WINDOWS\System32;C:\Programs\Java\jdk1.6.0\bin", but when i'm going to set the classpath and java_home variables it says that they are not recognized as an intern or extern command etc...
Could anyone please help me?
(I'm portuguese; sorry for my english...)

you don't need to set CLASSPATH. you should learn to use -classpath option on javac.exe and java.exe when you compile and run in a command shell.
if your PATH points to Java's /bin, you probably don't need to do anything else.
the right way to set environment variables in Windows XP is in the control panel.
if you want to set them just for one shell, and have them disappear when the shell is closed, you type "set JAVA_HOME=...." and "set CLASSPATH=...".
You'll find out quickly that CLASSPATH environment variables are ignored by javac.exe, java.exe, every IDE, and every Java EE app server. You have to learn how each one sets CLASSPATH.

Sick and tired og classpath and system properties

Now im really turned on! Its maybe the fifth time i have to reinstall. Why?
Because ANY change of weblogic.class.path seems to be irreversible, and the
wlconfig-"tool" not even act as in the documentation.
***How do I really change weblogic.class.path?
It does NOT seem to work, and when it works it appends just the new path to
alle other paths
***How do I set paths back to "zero"????? It seems impossible! Any change is
appearently a no-return operation where the possibilities is succes or
reinstall.
***Why is it not possible to edit some simple textfiles/scripts? Or why is
there not even some graphic tool like in all other apps? Its very strange
that a common thing lige some simple files is so hard for BEA to implement.
Its really, really, really annoying!!! I Use 5.1 and sp8. All the printed
documentation says that i shall use for instance
java -Dweblogic.class.path=xxx, but it doesnt work. It says also that I can
use wlconfig -classpath, but this messes CLASSPATH Prefix, classpath and
weblogic.class.path up, so the server cant run.
I have maybe done something wrong, but the documentation is certainly not
very helpful or accurate!
How do you really do it? It should not be so hard to do, becuase WL is
worthless without for instance a databasepool.

Now im really turned on! Its maybe the fifth time i have to reinstall. Why?
Because ANY change of weblogic.class.path seems to be irreversible, and the
wlconfig-"tool" not even act as in the documentation.
***How do I really change weblogic.class.path?
It does NOT seem to work, and when it works it appends just the new path to
alle other paths
***How do I set paths back to "zero"????? It seems impossible! Any change is
appearently a no-return operation where the possibilities is succes or
reinstall.
***Why is it not possible to edit some simple textfiles/scripts? Or why is
there not even some graphic tool like in all other apps? Its very strange
