Implementing a custom ClassLoader

Hi. I have found plenty of tutorials online about how to create your own custom ClassLoader but how do you actually go about indicating to the JVM that it should be using a custom ClassLoader for a given application? I can't figure it out.

It's quite interesting. Often I find that inquiries on ClassLoader are related to the poster's misunderstanding something, but yes, sometimes interesting things come up.
I want
to contrive some sort of mechanism for embedding java
code or some custom templating language in HTML. Hmm, like JSP?
I want to avoid having to recompile my whole
application each time i or someone else updates an
HTML template. It seems that a custom classloader is
the answer here where i could write a custom loader
that would detect recently modified HTML templates
and re-compile their associated .class file on the
fly before re-loading the class.I wrote one of these along time ago. Its a bit tricky, but its been done.
Why reinvent the wheel? I believe you could find one by doing a google for
DynamicClassLoader.
Take a look at janino, too.
Good luck.

  • 5.1 SP8 Custom ClassLoader ClassFormatError messages

    We use a custom ClassLoader that unscrambles classfiles not understood by its parent.
    When the Weblogic parent ClassLoader attempts discovers it can't decipher the
    file, it writes a ClassFormatError message and stack trace to the console (though
    not to the log) before delegating to its child (our code) which proceeds to load
    the class with no trouble. The result is that our product runs fine, but appears
    to be full of unloadable classes. How can we get the Weblogic ClassLoader to suppress
    these misleading error messages? (IMHO, it shouldn't report errors until and unless
    both it and its child have failed, but given that it does, is there some way to
    make it shut up?)

    You can use class preprocessor in WebLogic for that sort of thing (products
    like Wily and Tangosol use this feature to instrument or customize classes when
    they are loaded by WebLogic classloaders) without adding your own classloaders,
    for example, in 6.1:
    public class ExamplePreprocessor implements weblogic.utils.classloaders.ClassPreProcessor {
    public void initialize(java.util.Hashtable ht) {}
    public byte[] preProcess(String classname, byte[] classbytes) {
         ... unscramble or do whatever is that you do with classbytes ...
    return classbytes;
    and add this to the WebLogic command line :
    -Dweblogic.classloader.preprocessor=preprocessorclassname

  • Can we implement the custom sql query in CR for joining the two tables

    Hi All,
    Is there anyway to implement the custom sql query in CR for joining the two tables?
    My requirement here is I need to write sql logics for joining the two tables...
    Thanks,
    Gana

    In the Database Expert, expand the Create New Connection folder and browse the subfolders to locate your data source.
    Log on to your data source if necessary.
    Under your data source, double-click the Add Command node.
    In the Add Command to Report dialog box, enter an appropriate query/command for the data source you have opened.
    For example:
    SELECT
        Customer.`Customer ID`,
        Customer.`Customer Name`,
        Customer.`Last Year's Sales`,
        Customer.`Region`,
        Customer.`Country`,
        Orders.`Order Amount`,
        Orders.`Customer ID`,
        Orders.`Order Date`
    FROM
        Customer Customer INNER JOIN Orders Orders ON
            Customer.`Customer ID` = Orders.`Customer ID`
    WHERE
        (Customer.`Country` = 'USA' OR
        Customer.`Country` = 'Canada') AND
        Customer.`Last Year's Sales` < 10000.
    ORDER BY
        Customer.`Country` ASC,
        Customer.`Region` ASC
    Note: The use of double or single quotes (and other SQL syntax) is determined by the database driver used by your report. You must, however, manually add the quotes and other elements of the syntax as you create the command.
    Optionally, you can create a parameter for your command by clicking Create and entering information in the Command Parameter dialog box.
    For more information about creating parameters, see To create a parameter for a command object.
    Click OK.
    You are returned to the Report Designer. In the Field Explorer, under Database Fields, a Command table appears listing the database fields you specified.
    Note:
    To construct the virtual table from your Command, the command must be executed once. If the command has parameters, you will be prompted to enter values for each one.
    By default, your command is called Command. You can change its alias by selecting it and pressing F2.

  • Best practice question for implementing a custom component

    I'm implementing a custom component which renders multiple <input type="text" .../> controls as part of it. The examples I've seen that do something similar use the ResponseWriter to generate the markup "by hand" like:
         writer.startElement("input", component);
         writer.writeAttribute("type", "text", null);
         writer.writeAttribute("id", "foo", null);
         writer.writeAttribute("name", "foo", null);
         writer.writeAttribute("value", "hello", null);
         writer.writeAttribute("size", "20", null);
         writer.endElement("input");
    I don't know about anyone else, but I HATE having to write code that manufactures this stuff - seems to me that there are already classes that do this, so why not just use those? For example, the above could be replaced with:
         HtmlInputText textField = new HtmlInputText();
         textField.setId("foo");
         textField.setValue("hello");
         textField.setSize(20);
         // just to be safe, invoke both encodeBegin() and encodeEnd(),
         // though it seems like encodeEnd() actually does the work in this case,
         // but who knows if they might change it at some point
         textField.encodeBegin(context);
         textField.encodeEnd(context);
    So my question is, why does everyone seem to favor the former over the latter? Why not leverage objects that already do the (encoding) work for you?

    Got it!
    You JSP should have this:
    <h:panelGroup styleClass="jspPanel" id="jspPanel1"></h:panelGroup>
    And your code page ValueChangeListener/ActionListner should have this:
              if (findComponent(getForm1(),"myOutputText") == null)
                   FacesContext facesCtx = FacesContext.getCurrentInstance();
                   System.out.println("Adding component");
                   HtmlOutputText output =
                        (HtmlOutputText) facesCtx.getApplication().createComponent(
                             HtmlOutputText.COMPONENT_TYPE);
                   output.setId("myOutputText");
                   output.setValue("It works");
                   getJspPanel1().getChildren().add(output);          
                   System.out.println("Done");
                   DebugUtil.printTree(FacesContext.getCurrentInstance().getViewRoot(),System.out);
              else
                   System.out.println("component already added");
    I just have to figure out this IOException on the closed stream - probably has to do with [immidiate="true"].
    Thanks.

  • The struggle of creating a Custom ClassLoader for Native libraries

    Hello Everyone,
    I'm having a really hard time writing and using my own ClassLoader in a Java Applet.
    Context :
    As the this link shows - http://codethesis.com/tutorial.php?id=1 - loading and especially unloading native libraries through Java requires defining our own ClassLoader, and use it to instantiate a class loading a library. When the class using native libraries has finished execution, setting all references to the classloader and calling the garbage collector will cause the native library to be unloaded. The class to load within the custom classloader is thus read byte after byte from the jar and defined using the Classloader.defineClass(..) function. So that's what I did. But I've got two problems.
    Problem 1 :
    On one single machine over 15 tested, the magic number of a given class read from the Jar using Applet.class.getResourceAsStream(classname) takes a value different from CAFEBABE and the defineClass function then throws an "Incompatible magic value" exception (see below). The workaround I found is to force the first 4 bytes of the byte array read from the class with CAFEBABE. But I still would like to understand why it takes a different value on this machine.
    Exception in thread "thread applet-MyApplet.class-1" java.lang.ClassFormatError: Incompatible magic value 409165630 in class file Reader
    at java.lang.ClassLoader.defineClass1(Native Method)
    at java.lang.ClassLoader.defineClass(Unknown Source)
    at NativeClassLoader.findClass(Unknown Source)
    Problem 2 :
    On windows, the NativeClassLoader works perfectly, but on Linux, I'm getting a java.lang.VerifyError (see below).
    Code is compiled with java 1.6.0_06 on windows XP. I tried to remove everything related to native code (remove .so load), the same error is raised.

  • Custom classloader fails when using Java Web Start

    Hope you can help me with a problem that is driving me nuts. I have implemented my own classloader to support plugins. This classloader works as follows:
    1. The classloader is configured to access a plugin components jar file downloaded by jws.
    2. The plugin components jar file contains other jar files which contains the actual plugin code to be loaded using my own classloader.
    3. Upon initialization - my classloader extracts all jar files contained in the plugin components jar file into temporary files.
    4. These temporary files are used by my classloader when defining plugin classes.
    The classloader works fine when not using java web start. Then I launch the application using java web start with security policy in .jnlp file set to:
    <security>
    <all-permissions/>
    </security>
    After a while (it was able to load some of the classes) it fails with the following stack-trace:
    Regards,
    Terje

    Does anyone have source code for implementing a simple class loader that can be used with Java Web Start (preferrably with all jar files to be used by the classloader wrapped into a jar file)

    If you implement your own classloader, and then still run with a SecurityManager installed, then your ClossLoader is responsible for asigning the permissions to the code it loads.
    You need your ClassLoader to extend SecureClassLoader, and implement the method :
    SecureClassLoader.getPermissions(CodeSource cs) to return the PermissionCollection you want.

  • XMLEncoder stackoverflow problem with custom classloader

    Hi, All
    I'm tring encoding my object using XMLEncoder, the objects are from the custom classloader like URLClassLoader which is importing several jar files at run-time.
    source code is like this:
    XMLEncoder e = new XMLEncoder(new BufferedOutputStream(os));
    e.writeObject( sourceObj);
    When I run it, I experienced this error:
    XMLEncoder has "ClassNotFoundException" or "InstantiationException" problem.
    so I found very similar posting for this problem and modified it so that the XMLEncoder can find my classes from custom classloader:
    ClassLoader cl = this.getClass().getClassLoader();
    URLClassLoader urlClassLoader = new URLClassLoader(urls, cl);
    Thread.currentThread().setContextClassLoader(urlClassLoader);
    XMLEncoder e = new XMLEncoder(new BufferedOutputStream(os));
    e.writeObject( sourceObj);
    The result was slightly changed. However, still disappointing:

    When I finally include the jar files into the classpath so that the default classloader can reference them, the encoder worked properly.
    Anyone can help me?

    StackOverFlow is quite a gotcha in XMLEncoder it is often because of the following code in java.beans.PersistenceDelegate:
    public void writeObject(Object oldInstance, Encoder out) {
    Object newInstance = out.get(oldInstance);
    if (!mutatesTo(oldInstance, newInstance)) {
    out.remove(oldInstance);
    out.writeExpression(instantiate(oldInstance, out));
    else {
    initialize(oldInstance.getClass(), oldInstance, newInstance, out);
    and the following code in java.beans.DefaultPersistenceDelegate:
    protected boolean mutatesTo(Object oldInstance, Object newInstance) {
    // Assume the instance is either mutable or a singleton
    // if it has a nullary constructor.
    return (constructor.length == 0) || !definesEquals(oldInstance) ?
    super.mutatesTo(oldInstance, newInstance) :
    oldInstance.equals(newInstance);
    What this means is if you have a class (you want to persist) that has a constructor that takes arguments AND defines an equals method AND you have overridden initialize in DefaultPersistenceDelegate to do some extra work after it instantiates newInstance, then while the PersistenceDelegate is trying to generate you newInstance, oldInstance.equals(newInstance) will return false, and PersistenceDelegate will keep trying to instantiate a newInstance that does equal the oldInstance.
    So if you do use DefaultPersistenceDelegate then ensure that you override mutatesTo so that it is:
    protected boolean mutatesTo(Object oldInstance, Object newInstance) {
    return (newInstance != null && oldInstance.getClass() == newInstance.getClass());
    Here is an example PersistenceDelegate that persistence a class called PersistentBeanCollection, it calls its constructor with the property "type" and then calls the method add() on the newInstance.
    new DefaultPersistenceDelegate(new String[]{"type"}) {
    protected void initialize(Class type, Object oldInstance, Object newInstance, Encoder out) {
    PersistentBeanCollection oldBeanCollection = (PersistentBeanCollection) oldInstance;
    for (Iterator iterator = oldBeanCollection.iterator(); iterator.hasNext();) {
    out.writeStatement(new Statement(oldInstance, "add", new Object[]{iterator.next()}));
    protected boolean mutatesTo(Object oldInstance, Object newInstance) {
    return (newInstance != null && oldInstance.getClass() == newInstance.getClass());

  • Implementation of Custom Retractor in Cost Center Planning

    Hi All,
    I am facing a problem regarding Implementation of Custom Retractor.
    In our Project TM1 Server which is presently existing is to be replaced by BI server for Cost Center Planning.
    The value needs to be retracted back to the R/3 server for poplutaing the  Source Table fields.
    Now our Business requirement is best suited by implementing a Custom Retractor which would fetch the data from
    BI back to R/3 Server.I have some queries regarding this implementation.
    1> The Data load Function Module & Post Data Load Function Module which is implemented for Data loadinf into R/3 server
    is written in which server (BI / R3)? If its written in R3 as the case seems them how the BI table type needs to be declared in the
    function module?
    2> What the  Function Module is returning ..is it directly updating the DB table or returning a structure?
    Our project is still in the Realisation Phase....So no development has began yet....
    Eagerly waiting for your response.
    Thanks a lot..

    Hi Uryikin,
    Thanks for your response.
    Standard Retractor does not satisfy the Business requirement in full.
    The RFC connection you have suggested is what we are implementing through RSPLAN function Type creation.
    In the RSPLAN we are implementing a Class which will fetch the Data from the Infoobject.
    This infoobject will be fed from the target Infocube. After this Class getting populated Mapping will be done b/w BI source fields and the R/3 source fields.
    Now the problem arise when a Function Module needs to be created that will actually bring the data to R/3 side.
    The server where  Data Load function Module is to written is still unknown to me..
    The Function Module Return type is also unknown...
    As this is totally customised we have to identify the return type for submission of Blueprint...
    Kindly refer to this link we are implementing this same steps only on different scenario...

  • Best way to call custom classloader

    I have created a custom classloader to perform hot deployment for application server. How do I let JVM to use my class loader instead of system class loader?
    a. Using the command line argument -Djava.system.class.loader
    b. Using -javaagent and setting System.setProperty("java.system.class.loader", myclass) in premain method.
    c. Is there any other alternative?
    If I am using the command line approach, I will need to have my jar file in the classpath. What is the best way to do this?
    Thanks for your help

    Or you could write a small program which sets up the classloader and then loads the target program with it.

  • Customer ClassLoader:  keeping JWS from loading jars

    I really like the ability of JWS to be able to download jars required for my application to run, but there are several jars that I need the ability to load up via a custom ClassLoader. But because JWS includes all of these jars in the classpath upon application start, the system class loader will take the first class it can find. Because I need to load classes from these jars based upon something a user selects, I need to have control over the codesource for these classes. Does anyone have any ideas on how to tackle this problem? Not include the jars in the jnlp and then download if not cached locally, if that's the case what's the best way to do that? Include in jnlp and be able to load with custom classloader(I dont think this will work)? Any ideas on this would greatly be appreciated.

    Easiest solution to your problem and still being able to use the update mechanism of JWS is to include your JAR-file in another JAR-file that JWS loads, and then write up your own classloader, which tries to fetch your JAR-file from the downloaded JAR-file (if JWS already downloaded it, otherwise JWS will download it).
    The contents of the jws-stub.jar would be something
    of the following ;).
    jws-stub.jar
    --> myjar1.jar
    --> myjar2.jar
    org.myjar.MyJarClassloader
    Then based on your user selecting something you
    can decide which JAR-file you want to load, and thus
    which class.
    Hope this helped,
    Manfred.

  • Custom ClassLoader - trying to use different version of SNMP library than WebLogic Server 8.1 uses

    Problem: my J2EE ear file uses the AdventNet third-party library to do
    SNMP work. WebLogic Server 8.1 also uses this AdventNet third-party
    library to do its own SNMP work. The problem is the version used by
    WebLogic 8.1 is older than the version I use, so my code tries to run
    and finds the wrong version of the library that WebLogic 8.1 has supplied.
    Possible solution: I plan to have a custom classloader (derived from
    java.lang.ClassLoader) that gets hooked in to my threads using
    Thread.setContextClassLoader(). This custom classloader would look for
    the AdventNet library jars in a spot I specify so it would find the
    correct ones. Since I want to change the usual classloader behavior of
    "look in parent classloaders first, then child classloader" to "look in
    child classloader first, then in parent classloaders" I can't just
    override ClassLoader.findClass(). I, at a minimum, have to override
    ClassLoader.loadClass() to look in my classloader first. I have
    questions about this:
    1. What other methods do I have to override? For example, which of the
    resource-related methods do I need to override so that resources are
    searched for first in my classloader then in parent classloaders?
    2. I was thinking of using a URLClassLoader as a helper to my
    classloader, invoking its method(s) from my custom classloader's
    method(s) to actually load the classes from URLs that are not on the
    standard classpath. I was planning to set it up with a custom parent
    classloader that can't find anything, so that the helper URLClassLoader
    would only ever find classes/resources in the URLs I provide to it. Does
    this approach make sense? Have you seen anything like this done before?
    3. Is there any way around this problem besides a custom ClassLoader? A
    buggy custom ClassLoader would have problems which AFAIK would be
    difficult to track down as ClassLoader problems.
    Thanks in advance for any help you can provide.

    Hi,
    I am experiencing the same problme and
    even I tried to put the AdventNet jar files
    before weblogic.jar I still cannot get it
    to work
    Would you help me out here.
    Thanks,
    -AlvinI finally figured out a way to do it using a custom classloader that
    looked in the directory where I kept the version of AdventNet I wanted
    before looking in the normal places classloaders look.
    How it works is I hook two classloaders at the bottom of the chain of
    classloaders. My custom BlockingClassLoader is hooked as a child of the
    normal chain of classloaders, then a URLClassLoader is hooked under
    that. The BlockingClassLoader's findClass method checks if the class
    starts with a package prefix I want to control (like "com.adventnet.").
    If it does, then it acts like it can't find the class. This makes its
    child, the URLClassLoader, try to find the class. The URLClassLoader
    is given the URL of places to look for classes that match the directory
    I keep the version of AdventNet I want in. When I load a class, I
    directly tell the URLClassLoader to load it so that it is loaded as I want.
    There's more to it than this. I had to override some other methods in
    my BlockingClassLoader and do some other stuff. I'm not sure if I can
    share the source code, as it was developed on company time and thus is
    owned by the company. Feel free to ask questions though.
    I haven't tried this solution very long (basically just unit tested it)
    but it looks promising.

    Hi,
    I am using Adobe Flash Builder 4.6.I was trying to implement a custom logger with the logging API.

  • Custom ClassLoader

    I do not understand much how to create a simple custom class loader. I found many explaination about it. I don't really get what it means.
    Can anyone explain to me in simple code? My custom classloader doesn't work at all.
    I want to load a class in another package. How can I do it?
    Thanks

    What do you mean by "package"?

  • Custom classloader in Applet?

    Hi
    I have for some time tried to load an Applet from within an Applet by means of custom classloader.
    However when reading various specifications for classloader they state it is not possible for an Applet to do so.
    Does anyone know otherwise?

    Hi
    To be more specific.. I have 2 Applets yes. In the first signed Applet I run as a jar I have created a custom classloader that extends ClassLoader hence the java bytecode I wish to load (also an Applet) must be (a) class file(s). As far as I know the ClassLoader is not able to define classes from jars right?
    It is only the loading Applet that is packed as a jar and there is no nested jars. However the loaded Applet is now loaded as a class file but I would like to load is a jar for speeding up loading time.
    Quote from http://www.javaworld.com/javaworld/jw-10-1996/jw-10-indepth.html:
    There is a cost, however, because the class loader is so powerful (for example, it can replace java.lang.Object with its own version), Java classes like applets are not allowed to instantiate their own loaders. (This is enforced by the class loader, by the way.) This column will not be useful if you are trying to do this stuff with an applet, only with an application running from the trusted class repository (such as local files).
