Using 3rd party jar file in WCEM3.0

Hi,
I want to get data from an external database into WCEM. Is it possible to use MySQL connector jar for achieving this?
I used the MySQL connector jar but my guess is, it does not get deployed to the server. It is just visible in my local development.
When I try to connect to the database I get an error saying "could not find a suitable JDBC driver".
I need some guidance.
Regards,

Hi Steffen,
As per your suggestion I was able to ping the database manually, but when I try to access it from my code which runs on the server I am getting the exception that I have stated below.
But if I want to connect to the database dynamically, what then? I am using the MySQL connector jar file for this purpose but on deploying the code to the server I get the error as "Could not find a suitable driver".
I think the jar file is not getting deployed to the server. Are there any steps that I would have to follow to deploy it?

  • How to use 3rd party jar files for xml transform

    Hi all,
    Am using OAS9.0.4 and I deployed my .ear successfully.
    In my application am using 4 jar files for xml transformation. (xerces.jar, xalan.jar, xml-apis.jar,xercesImpl.jar)
    OAS has its own xmlparserv2.jar file. Its using this jar file for transforming xml data and not even looking for above mentioned 4 jar files.
    In opmn.xml, I provided these 4 jar files in to class path. Then also it didn't effect my output.
    I also tried as put these 4 jar files into j2ee\home\applib directory, but o result.
    Can anybody tell me where should I keep these 4 jar files in OAS and OAS should use these 4 jar files instead of its own xmlparserv2.jar for transforming data.
    Thanks in Anticipation,
    Regards,
    RK

    Add the Xbootclasspath variable in the java-options field. It will somewhat look like the following in your opmn.xml file
    <process-type id="<OC4J Instance Name>" module-id="OC4J">
    <module-data>
    <category id="start-parameters">
    <data id="java-options value="........... -Xbootclasspath^/a:<location of your jar files>" />
    Ensure to use th ^/a (append) signature

  • 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.

  • Using loadjava utility to load a 3rd party jar file

    Hi Folks,
        I need to validate if a java class, stored into an Oracle Database, is able to connect to a SQLite database.
        In order to connect to SQLite I'm using the the jar file sqlite-jdbc-3.7.2.jar that I got from  https://bitbucket.org/xerial/sqlite-jdbc/downloads
        Then I tried to load the jar file into Oracle Database using the command:
        loadjava -resolve -user system/xpto@tm014_23 -schema novacap sqlite-jdbc-3.7.2.jar
        The result is a series of error messages with the error code ORA-29533.
        Ex: - Attempt to overwrite class or resource org/sqlite/Codes while defining or compiling SYSTEM.org/sqlite/Codes
        Can you guys help me?
    Thanks,
    Luis

    I need to validate if a java class, stored into an Oracle Database, is able to connect to a SQLite database.
    You need to explain that a little more.
    How could a java class within Oracle connect to a SQLLite database if the driver it needs isn't already loaded into Oracle.
    The fact that you have to load the driver jar file tells you that the class will not be able to connect to SQLLite.
    The recommended way to develop with 'Java in the database' is to first write and test the code OUTSIDE the database. Then when it works load it in the databse.
    So use a copy of the Java class and test it outside the database to see if it can connect.
    Also since 11g you could just load that jar as a 'database resident' jar file. If you don't do that then Oracle just extracts all of the files in the jar and tries to load them one at a time. So using 'resolve' won't work because Oracle isn't going to load the classes in the proper order.
    See 'database resident jars' in the Java Dev Guide
    http://docs.oracle.com/cd/B28359_01/java.111/b31225/chtwo.htm#BEJCBAHI
    Database Resident JARs
    Starting with 11g release 1 (11.1), when you load the contents of a JAR into the database, you have the option of creating a database object representing the JAR itself. In this way, you can retain an association between this JAR object and the class, resource, and source objects loaded from the JAR. This enables you to:
      Use signed JARs and JAR namespace segregation in the same way as you use them in standard JVM.
      Manage the classes that you have derived from a JAR while loading it into the database as a single unit. This helps you to prevent individual redefinition of the classes loaded from the JAR. It also enables you to drop the whole set of classes loaded from the JAR, irrespective of the contents or the continued existence of the JAR on the external file system, at the time of dropping it.
    In order to load a JAR into the database, you have the following options of the loadjava tool:
      -jarsasdbobjects
      -prependjarnames
    For more information regarding the loadjava tool options, refer to "The loadjava Tool" section.

  • How can I include 3rd party jar files with my custom extention?

    I'm writing an extension that is dependent upon some 3rd party jars. How can I include/package these with my extension?
    we're using the 11g tech preview
    thanks,
    Dylan

    Do you mean that you need these files to appear in JDeveloper as a library available for the developers who build a project and use your extension?
    You can create a library in JDeveloper with JAR files by simply adding the following to your extension.xml file:
    <jdeveloper-hook xmlns="http://xmlns.oracle.com/jdeveloper/1013/extension">
    - <libraries xmlns="http://xmlns.oracle.com/jdeveloper/1013/jdev-libraries">
    <library name="My Extension Library">
    <classpath> ${ide.extension.install.home}/lib/some.jar</classpath>
    </library>
    </jdeveloper-hook>

    If you directly include classes12.jar in IRMASSvrMgntGUI.jar, the classloader won't be able to find the classes inside classes12.jar. You should sign classes12.jar separately and include that in jnlp along with your application specific jar. When you're launching your app using "java -jar somefile.jar" then the classpath settings in manifest file are used, but that's not the case when you start using JWS since in this case the classpath is based only on the " <jar href=..." entries in jnlp.

  • OSGI bundle creation using third party jar files

    Hi,
    I have a requirement to integrate our CQ5.5 based application with a third party. As part of this, I have to use some jar files. After lot of digging, I realised that the way to use external jar files is to create an OSGI bundle wrapping these jar files.
    So, I tried to do the same, but when I see the service details in system/console, I see errors. Can someone please suggest what could have gone wrong?
    I have to use 3 jar files. So, I placed them in lib folder as shown in the screenshot below.
    Ibuilt the bundle using .bnd file. It generated a jar file in install folder and I am able to to see its details in system/console/bundles. When I try to view details of the OSGI bundle that is installed, I see errors as follows:

    Here is my bnd file with all directives:

    And here is what is shown in systems/console/bundle:

    Regarding Export-Package, I know the function, class and its package I need to use. Would it be fine if I just export that package instead of using '*'? In such case, if this has dependency on some function in one of the 4 jar files I need to use, how does it get resolved? Do I need to Export those packages as well?

  • Using Third-Party jar file in database; Where to put license file?

    Hi!
    I have a third-party product that has a .jar file that references some .so files. I have successfully loaded the .jar file and the .so files are being called successfully, but when the program gets to the part where it reads the third-party license file, it is failing (ORA-3113 and an hs_err_pid<12345>.log and udump file are created. I know the issue is the location of the license file because I am getting the same exact error when I run it outside of the database. (I have been able to run it successfully outside of the database.)
    The instructions for the third-party product say to put the license file in the application's runtime directory.
    What I can't figure out is this: What is the application's runtime directory when I am running the code in the database?
    I thought it would be user.dir which is set to $ORACLE_HOME, but putting the license file there didn't work. I have tried lots of other places under $ORACLE_HOME.
    Any ideas?
    Thanks,
    Laurel

    Hi Laurel:
    Whether or not you can read the license file, sure you will have problem then when trying to load your .so file.

  • Using 3rd Party packages when creating jar - program doesn't run

    I am using the xerces and xom packages for xml etc in my program.
    It works fine when run from a command prompt, but as soon as I package it into a jar I get the java.lang.NoClassDefFound error for the nu.xom.Builder class (one of the 3rd party classes.)
    Reading through these forums has yielded several suggestions, none of which work.
    I am probably making some massive stupid mistake, but cannot see it...
    My manifest:
    Manifest-Version: 1.0
    Created-By: 1.6.0 (Sun Microsystems Inc.)
    Main-Class: be.bavardage.vocab.VocabGUI
    Class-Path: serializer.jar xercesImpl.jar xercesSamples.jar xml-apis.jar xom-1.1.jar
    using the jar comand line prompt:
    jar cfm vocab.jar MANIFEST.MF be\bavardage\vocab\*.classCan anyone give me any indication as to what I am doing wrong...

    bavardage,
    I too am reading forum messages to try to do just what you originally wanted to do. I have 3rd party JARs and I have always first extracted them and then turned around and JAR'ed them up into my single Remote.jar (actually I'm so new to Java that I don't yet change things that aren't broken and this was working when I got it)
    jar  xf  jakarta-oro-2.0.5.jar
    jar  xf  jasperreports-1.2.1.jar
    jar  xf  iReport.jar
    jar cmf  mainClassSpec  Remote.jar  *.class  org/  net/  it/I am reading the forums for a way to NOT do this. My reason is because I want to make the application Java Web Start (JAWS) capable. By zipping all the JARs up into one I end up with a JAR over 6 MB! I am also adding internationalization and I really need to keep the ListResourceBundle classes in a separate JAR so I can keep adding languages and not cause the entire 6 MB file to be downloaded each time.
    Using Java Web Start is the real motivating force here. I need to keep all JARs separate so that when there are code changes or new languages only one small JAR will be downloaded again by JAWS not the huge iReport.jar file at 4,218KB nor the somewhat smaller jasperreports...jar at 1,225KB (at 64KB jakarta-oro...jar is hardly worth mentioning) .
    I will watch this thread to see if you or anyone else later comes up with the information to reference external JARs (while in a Java Web Start environment).
    So to put it in a question format, can anyone provide some information about referencing external JARs in a normal environment and will it work in a JAWS environment (I do know the technique for specifing and downloading multiple JARs in a JNLP file)?
    Hopi(ng)

    Are you using Application Server Release 3 or Release 2? There are different versions listed in your mail.
    I think you probably want to add this as a shared library via EM and then import the shared library to your application with the application's xml config files.

  • Applets and 3rd party jars

    Hi,
    I'm trying to use a 3rd party jar with an applet. I can access the functions just fine when using an applet viewer, but when I try deploying the applet from a web page I get classNotFound exceptions. How do I go about getting the applet to recognize the jar file?
    Thanks

    Eva, yes, if that class in one of the 3rd party jars wants to access your class directly, then it is necessary that your class is loaded by the same classloader that loads that 3rd party jar or even higher up the classloader hierarchy.
    Why do you consider putting your class library into applib "a bit rude"? As long as your classes are named distinctively so that they will not clash with other classes, it is not a problem.
    On the other hand, it seems that the design of that 3rd party class is not classloader friendly. Had it used something like the following to load a class that is undefined at the compile time, you might not have this problem.
       Class userClass = Thread.currentThread().getContextClassLoader().loadClass(nameOfUserDevelopedClass);
       Object plugin = userClass.newInstance();

  • Problem deploying new version of 3rd party jar

    I have a third party jar file that was recently updated with to a new version. I deleted the old jar file and replaced it with the new version. Modified classpath accordingly. The strange thing is that the only way I could get the classes that use this jar file to work was to recompile them. What am I missing?

    When replacing a jar file it is alway a good idea to recompile against it... this ensures backward compatibity and also prevents Incompatible Class Change Errors. Your new 3rd party jar may not be completely backwards compatible, although it is always a good idea to recompile when implementing a new jar that your application depends on.

  • Signing of 3rd Party jars

    I have developed an app which uses Java Web Start. I created a self signed certificate for now an that works fine.
    What I was wondering about was 3rd party jars. Are they responsible for their own signing if they do system or disk I/O? Do I need to contact the vendor to get a signed version? I don't think I should be signing someone elses archive files.
    I need to run with all permissons set.

    My understanding is that if you sign one jar, you need
    to sign them all (and with the same certificate).This is only true within the the same jnlp file - not within the whole app.
    You can factor out sets of jar files into component extenions (a seperate jnlp file referenced by the original jnlp file.)
    Each component extension can have or not have the all-permissions tag, and if it does, the set of jar files in it can be signed by the same or a diferent certificate chain than the original.
