WebLogic cache classes API

I've used the WebLogic cache tag libraries in a portal application - with success. But then I would like to use the cache API from Java code also, and I went looking for documentation. There weren't much documentation on these classes and after doing a grep on weblogic.jar I found a package named weblogic.cache. I tried to look at the API documentation, but these classes weren't inlcuded in the JavaDocs available on e-docs.
What's the reason for not exposing these libraries with API documentation and tutorials/articles on how to use them? Do BEA recommend using third party cache libraries instead? I know that tangsol have a product, but my needs are simple and I don't want to use a product for these simple needs, and I don't want to implement them myself either.

I have similar need to cache simple POJO objects in clustered environment. Does WebLogic 8.1 Server offers any caching feature similar to p13n cache in WebLogic Portal server?
Thank you

  • Weblogic startup class and EAR file

    Hi,
    I am using WL 8.1.5.
    I have a weblogic starup class MyStartup that implements T3StartupDef. (it does not specify package).
    I jar-ed it. And I placed MyStartup.jar file into the MyEA.ear file. And I placed that into applications dir.
    With WL Console I defined the startup class and for the ClassName specified MyStartup.
    Yet I get the java.lang.ClassNotFoundException.
    I also have a Manifest.mf file with
    Class-Path: MyStartup.jar
    Please help me solve this problem, I literally don't know what to do next.

    Hi,
    thanks.
    This seems like a completely opposite method of the depplying startup class with weblogic console.
    Does my class still need to implement T3StartupDef?
    I get this exception. And my classnotfound is still there.

  • Weblogic Startup Class does not run as Windows Service

    If you know the answer, plase send me an email at [email protected]
    I'm running a weblogic startup class that starts a Thread. I need to
    run a batch program that should be running as long as WebLogic is
    running (to process new orders).
    It works fine when I run WebLogic (5.1 SP8) from a script, but causes
    problem when I'm running it as a Windows Service. It calls the
    startup class, however, the startup class never spawns the Thread
    class.
    Following is excerpts from different components:
    =============================================================
    *** weblogic.properties ***
    weblogic.system.startupClass.pdfCreatorStart=WebLogicStartupPdfCreator
    *** WebLogicStartupPdfCreator.java ***
    public class WebLogicStartupPdfCreator implements T3StartupDef {
    public String startup(String name, Hashtable args) throws
    Exception {
    Thread t = new ProductionPdfBatchRunner();
    t.start();
    return "success";
    *** ProductionPdfBatchRunner.java ***
    public class ProductionPdfBatchRunner extends Thread {
    public void run() {
    try {
    //work being done here
    this.sleep(30000);
    catch (InterruptedException ie) {               
    catch(Exception e) {
    e.printStackTrace();

    Thanks for any help

    Hi,
    Ok. Few suggestions.
    1. Can you review the SAP note:
    552286  Troubleshooting for the SAP Web Dispatcher
    2. When you said: "web dispatcher does not get started ", what error you got ? Can you be more details here ?
    3. Please check the trace file dev_webdisp" that generated in the work directory. If the log entries is not abvious, increase the trace level to 2 or 3, and reproduce and re-check the trace file.
    4. What is the output of the command "sapwebdisp -v"
    5. How about sapwebdisp.pfl ? Are those settings correct ?
    Hope this helps.
    Regards,
    Vincent

  • Clear the weblogic cache

    Hi All
    Please let me know how to clear the Weblogic cache folder (ie. <bea_home>/user_projects/domains/<app_domain>/servers/
    <app_name>/tmp/_WL_user) upon each restart of the server?
    I am using Weblogic 9.1 and application is deployed using
    exploded mode
    Thanks.

    We have seen that error as well. When using entity beans, we could do some creates, but then we would get the Cursor error. It would happen sporadically.
    IBM now has better Type 4 drivers with version 8.2, we are having better luck with them then with the BEA drivers.

    Hello All,
    I would like a client java program to communicate with a WLS over a t3s
    connection with two-way SSL.
    We have generated certificates for browsers that work fine for the two-way SSL.
    I have access to the base 64 encoded certificate that the java client program
    can use. I am assuming I need a private key also for use in the
    setSSLClientCertificate(InputStream[] chain) method for decryption of data
    coming to to the client. For a WLS server, this is no problem.
    Question(s): Am I correct in this private key assumption? If I do need the
    private key, how could I get it.
    Thanks

  • Weblogic User class extends deprecated class?

    weblogic.security.acl.User extends java.security.Identity which is a
    deprecated class for Java 1.2
    I checked the 5.1 API docs, this class still extends the
    java.security.Identity. Are there any plans to update this class or if there
    is another class we should use instead of weblogic.security.acl.User ?
    Srikanth Meenakshi

    s> weblogic.security.acl.User extends java.security.Identity which is

    This is not a problem. It's okay to use it.

  • How to use weblogic.logging classes in 6.0

    Hi,
    We developed a number of logging classes under 5.1. One used
    weblogic.logging.LogOutputStream to write messages out to the log. This
    code no longer works under WLS 6.0. Everything compiles and runs but I
    don't see any of our messages in any of the log files. Judging from the 6.0
    JavaDoc, it looks like LogOutputStream is no longer supported. So I
    switched over to using NonCatalogLogger. Same results - no output in the
    logs.
    What am I missing?
    Thanks.

    My coding error. weblogic.logging.* classes work just fine in 6.0 (he said

  • Clear KM Cache using API

    Hi All,
    We have a requirement to clear the KM cache every day in the morning for two of the items in Cache Monitor.  I would like to know if we could clear the cache for the selected items using some API or any and schedule a job so that it runs every day to clear the cache.
    Appreciate any suggestions for the same.

    check out this one:

    something like

  • Is WebLogic JMS C API backwards compatible with 8.1

    I need to be able to send a JMS message from a C++ legacy application, so I am looking at using the JMS C API to do this. However, I am stuck with using WebLogic Server version 8.1. The JMS C API came out with version 9, so I am wondering if it would be possible to use it with 8.1?
              Can this be done? Thanks in advance.

    I've shot off an internal email to see if I can get an answer - I'll post again if I get one. Some notes:
              - Prior to 9.0, there was a separate C-API kit available on dev2dev which is supported (via this newsgroup only), I don't know where it is now.
              - I think its likely the 9.0 C-API will work with an 8.1 client (or 7.0 for that matter), I just don't know if this usage supported.
              - You could use the 9.2 C-API with a 9.2 client to communicate with an 8.1 server. This is definitely supported.
