CLASSPATH and Packages

Hi
i get a
i just reorganised my java classes in packages (first time i use packages). After building up the directory tree representind the packages and adding the package statement to the classes i compiled them and everything seems to be find.
Then i added the path to my package to the classpath. Then i thought everything should be done and run fine.
But it doesn't. When i try to execute a simple test application (named TestApp, kind of Hello World) that resides in my package i get the well known error: "Exception in thread "main" java.lang.NoClassDefFoundError: TestApp". No matter if i call the the Application with "java TestApp" from it's own directory, the myfiles directory or form anywhere in my file system.
As far as i know this useally indicates a problem with the classpath. I tried to set the classpath like "java -cp d:\myfiles TestApp" but this didn't work. Of course i also tried to set the classpath within the Windows System Env. Variable. No success.
Does anyone has an idea what i'm doing wrong?
My Settings are:
OS: Windows 2000 pro
Root Dir where Java Runtime Env is installed: "d\:j2re1.4.2_05"
Windwos Env. Variable PATH: ".;d\:j2re1.4.2_05\bin"
Root Dir where my package resides: "d:\myfiles\"
Windows Env. Variable CLASSPATH: ".;d:\myfiles;d\:j2re1.4.2_05\lib\ext"
Path to TestApplication: "d:\myfiles\com\myname\myapplication\TestApp"
I hope some could help - i'm trying to track that problem down for about a day now and i'm getting a little bit frustrated.
Tanks a lot for your help!
Frank

You must use the fully qualified class name to launch an application. If TestApp is in a package named com.myname.myapp, then the command must be "java com.myname.myapplication.TestApp"

  • Need help about classpath and packages

    I am new to jAVA and trying to learn packages.I wrote a java programme called AccountBalance.java with package MyPack;
    I set the classpath as C:\java programs\MyPack.
    My java program was compile fine BUT classes were not creating in MyPack folder.
    Cananyone suggest how java programs create the classes in ClassPath specified folder automatically.
    Thanks

    Here you want to create your class file in a separate package.
    Actually the creation of class will happen at the time of compilation.
    So you have to take care about it at the time of compilation.
    try this one to compile your source file:
    javac <java source file name> -d <targetplace>
    the java source file name is your source file name and -d is switch that is used to create the package(directory) and the target place is the location where you want to create your package. if you want to create your package in the current directory then you can simply give
    javac <java source file name> -d .
    try this one all the best. if it's not working then reply me so that i can check myself and try to find another solution for that.
    thank you
    bye

  • A question about CLASSPATH and Package

    The configuration of my computer is:
    Windows98, C:\j2sdk1.4.0
    Which in Autoexec.bat are included like this:
    path=C:\j2sdk1.4.0\bin
    set CLASSPATH=C:\j2sdk1.4.0\lib
    Then I make a new directory named t in C:\j2sdk1.4.0\lib, where there is a compiled file a.class, source code is:
    package t;
    public class a
    And another java file was in D:\t, named b.java, code like this:
    import t.*;
    class b extends a
    public static void main( String[] args )
    System.out.println("OK");
    Then I compiled like this: javac b.java, it was wrong; but when I compiled like this: javac -CLASSPATH C:\j2sdk1.4.0\lib b.java, It was OK!!! Why?? And then when I execute like this: java b, an error message was prompted(Can not find class t/a)!!! How can I do?

    First one general comment: I would not advise putting your own classes into C:\j2sdk1.4.0\lib since this suggests that the classes under this directory belong to the Java distribution. So my advice: create your own directory somewhere like D:\user\Classes or whatever.
    The directory (-ies) you specify in CLASSPATH are root entries telling the JVM where to start looking for classes. Why root entries? Well, the package structure is reflected in the directory structure relative to these roots. So a class of package t belongs into the subdirectory t of one of the directories specified in your CLASSPATH. This would be the case of your class a - by the way, the convention says that class names are capitalized. Since class b, on the other hand, is not in any package, it belongs irirectly into one of the directories of your CLASSPATH.
    Whereas the compiler is fairly forgiving about the location of your source files, the JVM is not. Invoking a class of some package requires you to provide the fully-qualified name to the java command. So if you wanted to run class a, you would have to invoke "java t.a". Starting class b, simply requires a call of "java b". But make sure the class file of class a is located in the subdirectory t of one of the directories specified in your CLASSPATH.

  • Classpath and 3rd party jar files

    We have been searching for a long time and have not been able to find an answer to our question. Do you think that you could help us out?
    We need to include 3rd party jar files in our application. Where in the deployment classpath directory structure can we place these. This does not seem to happen when we publish.
    We also need to give our clients the ability to modify our configuration. Currently we do this with an xml file, which we place under server/config in our JBoss directory. We also need to find a home for out log4J configuration file.
    Where does this type of thing exist in the SAP world?

    We have had problems with 3rd party jar files also. We ended up including them in the WEB-INF/lib directory of our WAR file and packaging/deploying them everytime.
    If you are looking for your project on your server, it is deployed to a directory similar to this:
    /usr/sap/J01/JC00/j2ee/cluster/server0/apps
    Hope this helps.

  • 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?

    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>

  • Classpath and sourcepath

    Dear Sirs;
    I have been having problems with the classpath and sourcepath commands. I am using a Windows NT system. The Sun Certified Programmer for Java 2 stated that the information on setting up the environment would be in the main directory for Java. I have not found this to be the case. I cann't set either of the variable from the control panel. I have been able to key in the following;
    Javac directory\program.java
    This places the class in the same directory.
    Any information you can provide is greatly appreciated.
    Thanks

    Source path is where you're editor/compiler will look for your files to edit/compileNo.
    'sourcepath' is a command line option for javac.
    I remember that it was rather quirky. But its purpose seems to be to allow the dependency checker in the compiler to find other java files that are not in the same package as the compiled code. And compile them if needed.
    I finally decided that it was just easier to handle my own dependencies via make.

  • How to copy procedures and packages from one server to another?

    Hi,
    I have 439 packages and 178 procedures located in one server called MAXWELL.
    I need to copy these objects to another server called TITAN.
    The schema names is SPCBR in both servers.
    So both servers have an instance running with this schema SPCBR.
    SPCBR in TITAN server has their tables with table data which was generated by an export/import process from MAXWELL server.
    However, procedures and packages were not copied by the export/import because I used the clause 'tables'.
    Now, what can I do in order to equalize procedures and packages in both databases? I can't risk in damaging or duplicating data in my database located in TITAN server, ok?
    Thanks,

  • Unicode export:Table-splitting and package splitting

    Hi SAP experts,
    I know there are lot of forums related to this topic, but I have some new questions and hence posting a new thread.
    We are in the process of doing unicode conversion in our landscape(CRM 7.0 system based on NW 7.01) and we are running on AIX 6.1 and DB2 9.5. The database size is around 1.5 TB and hence, we want to go in for optimization for export and import in order to reduce the downtime.As a part of the process, we have tried to do table-splitting and parallel export-import to reduce the downtime.
    However, we are having some doubts whether this table-splitting has actually worked in our scenario,as the export has exeucted for nearly 28 hours.
    The steps followed by us :
    1.) Doing the export preparation using SAPINST
    2.) Doing table splitting preparation, by creating a table input file having entries in the format <tablename>%<No.of splits>.Also, we have used the latest R3ta file and the dbdb6slib.o(belonging to version 7.20 even though our system is on 7.01) using SAPINST.
    3.) Starting with the export using SAPINST.
    some observations and questions:
    1.) After completion of tablesplitting preparation, there were .WHR files that were generated for each of the tables in DATA directory of export location. However, how many .WHR files should be created and on what basis are they created?
    2.) I will take an example of a table PRCD_CLUST(cluster table) in our environment, which we had split. We had 29 *.WHR files that were created for this particular table. The number of splits given for this table was 36 and the table size is around 72 GB.Also, we noticed that the first 28 .WHR files for this table, had lots of records but the last 29th .WHR file, had only 1 record. But we also noticed that, the packages/splits for the 1st 28 splits were created quite fast but the last one,29th one took a long time(serveral hours) to get completed.Also,lots of packages were generated(around 56) of size 1 GB each for this 29th split. Also, there was only one R3load which was running for this 29th split, and was generating packages one by one.
    3.) Also,Our question here is that is there any thumb rule for deciding on the number of splits for a table.Also, during the export, are there any things that need to be specified, while giving the inputs when we use table splitting,in the screen?
    4.) Also, what exactly is the difference between table-splitting and package-splitting? Are they both effective together?
    If you have any questions and or need any clarifications and further inputs, please let me know.
    It would be great, if we could get any insights on this whole procedure, as we know a lot of things are taken care by SAPINST itself in the background, but we just want to be certain that we have done the right thing and this is the way it should work.
    Regards,
    Santosh Bhat

    Hi,
    First of all please ignore my very first response ... i have accidentally posted a response to some other thread...sorry for that 
    Now coming you your questions...
    > 1.) Can package splitting and table-splitting be used together? If yes or no, what exactly is the procedure to be followed. As I observed that, the packages also have entries of the tables that we decided to split. So, does package splitting or table-splitting override the other, and only one of the two can be effective at a time?
    Package splitting and table splitting works together, because both serve a different purpose
    My way of doing is ...
    When i do package split i choose packageLimit 1000 and also split out the tables (which i selected for table split)  into seperate package (one package per table). I do it because that helps me to track those table.
    Once the above is done i follow it up with the R3ta and wheresplitter for those tables.
    Followed by manual migration monitor to do export/import , as mentioned in the previous reply above you need to ensure you sequenced you package properly ... large tables are exported first , use sections in the package list file , etc
    > 2.) If you are well versed with table splitting procedure, could you describe maybe in brief the exact procedure?
    Well i would say run R3ta (it will create multiple select queries) followed by wheresplitter (which will just split each of the select into multiple WHR files)  ...  
    Best would go thought some document on table spliting and let me know if you have specific query. Dont miss the role of hints file.
    > 3.) Also, I have mentioned about the version of R3ta and library file in my original post. Is this likely to be an issue?Also, is there a thumb rule to decide on the no.of splits for a table.
    Rule is use executable of the kernel version supported by your system version. I am not well versed with 7.01 and 7.2 support ... to give you an example i should not use 700 R3ta on 640 system , although it works.
    >1.) After completion of tablesplitting preparation, there were .WHR files that were generated for each of the tables in DATA directory of export location. However, how many .WHR files should be created and on what basis are they created?
    If you ask for 10 split .... you will get 10 splits or in some case 11 also, the reason might be the field it is using to split the table (the where clause). But not 100% sure about it.
    > 2) I will take an example of a table PRCD_CLUST(cluster table) in our environment, which we had split. We had 29 *.WHR files that were created for this particular table. The number of splits given for this table was 36 and the table size is around 72 GB.Also, we noticed that the first 28 .WHR files for this table, had lots of records but the last 29th .WHR file, had only 1 record. But we also noticed that, the packages/splits for the 1st 28 splits were created quite fast but the last one,29th one took a long time(serveral hours) to get completed.Also,lots of packages were generated(around 56) of size 1 GB each for this 29th plit. Also, there was only one R3load which was running for this 29th split, and was generating packages one by one.
    Not sure why you got 29 split when you asked for 36, one reason might be the field (key) used for split didn't have more than 28 unique records. I dont know how is PRCD_CLUST  split , you need to check the hints file for "key". One example can be suppose my table is split using company code, i have 10 company codes so even if i ask for 20 splits i will get only 10 splits (WHR's).
    Yes the 29th file will always have less records, if you open the 29th WHR you will see that it has the "greater than clause". The 1st and the last WHR file has the "less than" and "greater than" clause , kind of a safety which allows you to prepare for the split even before you have downtime has started. This 2 WHR's ensures  that no record gets missed, though you might have prepared your WHR files week before the actual migration.
    > 3) Also,Our question here is that is there any thumb rule for deciding on the number of splits for a table.Also, during the export, are there any things that need to be specified, while giving the inputs when we use table splitting,in the screen?
    Not aware any thumb rule. First iteration you might choose something like 10 for 50 GB , 20 for 100 GB. If any of the tables overshoots the window. They you can give a try by  increase or decrease the number of splits for the table. For me couple of times the total export/import  time have improved by reducing the splits of some tables (i suppose i was oversplitting those tables).

  • How can I compile all functions, procedures and packages with a script?

    I need to compile all functions, procedures and packages of 5 schemas (users) with a script.
    How can I do it?
    Thanks!

    you can create a script to select all invalid objects in those schemas Since Oracle 8 introduced NDS this approach has struck me as a trifle old fashioned. It's much simpler to loop round the query in PL/SQL and use EXECUTE IMMEDIATE to fire off the DDL statements. No scripts, no muss, no fuss.
    Having said that, the problem with this approach and also with using DBMS_UTILITY.COMPILE_SCHEMA is that they do not compile all the invalid objects in dependency order. This may result in programs being invalidated by the subsequent compilation of dependencies. This is due to the introduction of Java into the database.
    The UTLRP script is much better, because it (usually) avoids cyclic references. But you still may need to run it more than once.
    In general it is better to avoid sledgehammer recompilations (like DBMS_UTILITY.COMPILE_SCHEMA, which starts by invalidating all the objects). If we have twenty invalid objects, nineteen of which are dependencies of the twentieth, we actually only need to recompile the master object, as recompiling it will trigger the recompilation of all the others.

  • 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 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

  • 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.

    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]
    How Classes are Found:
