Recently while writing a program which takes large amount of memory I ran into this runtime error. And it is giving me nightmares, as I have a very important deadline to meet. The program takes large amount of memory so I tried increasing the heap size and set the following options for the vm -verbosegc -ms128m -mx128m Also, at one or two places I am explicitly calling gc, to help free up some memory. The time the program will take to execute is not a concern as long as it runs smoothly. Attached is a part of the trace of the gc run and the run time error. How to fix this bug? And is it memory allocation which is causing it? Any help on this will be heartily appreciated.

Memory settings are a part of the -X settings Further, this is not an expert opinion only my own: - I would recommend against doing your own gc too increase performance, the jvm does that better than you. However you can hint to the jvm what kind of gc you need. (see links) I would do this: 1. Increase heap size to make the application work 2. Check with som kind of analyzing tool what eats up your memory, and check to see whether the architecture can be less memory consuming. 3. Give correct jvm/hotspot parameters to maximise performance for this particular application (see links) Hotspot performance: http://java.sun.com/docs/hotspot/gc1.4.2/ JVM options: [http://java.sun.com/docs/hotspot/VMOptions.html] Good luck. asaguden ============================================================================== TOPIC: Java was created in SODOM and GOMORRAH !!!! http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/241d795807847c94 ============================================================================== == 1 of 4 == Date: Tues, Dec 21 2004 11:11 am From: "Azeus" "Bruno Beam" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > JAVA was written by SATAN in SODOM with help of the ANTICHRIST > in GOMORRAH !!!

Here is my XML file : <?xml version="1.0" encoding="ISO-8859-1"?> <docExcel> <onglet name="Lot1"> <cellule positionX="F" positionY="4" type="pourcent"> <seuilBas positionX="E" positionY="4"/> <seuilHaut positionX="D" positionY="4"/> <indicateur name="transfert_de_fichiers" periodicite="hebdo"/> </cellule> </onglet> </docExcel> I want to set the relationship between cellule and onglet, by calling a setOnglet(Onglet ong) method on a Cellule object. Here is my code : Digester mapping=new Digester(); mapping.setValidating(false); mapping.addObjectCreate("docExcel",DocExcel.class); mapping.addObjectCreate("docExcel/onglet",Onglet.class); mapping.addSetProperties("docExcel/onglet"); mapping.addObjectCreate("docExcel/onglet/cellule",Cellule.class); mapping.addSetTop("docExcel/onglet/cellule","setOnglet","divData2csv.excel.Onglet"); mapping.addSetProperties("docExcel/onglet/cellule"); So, in the Digester's stack, from bottom to top, I have a DocExcel, an Onglet, and a Cellule. According to the documentation, the addSetTop method should call the setOnglet method on the top object (Cellule), passing the top-1 object (Onglet) as an argument. When I execute my program, I have this in the log file : - Fire begin() for SetTopRule[methodName=setOnglet, paramType=divData2csv.exel.Onglet] - Fire begin() for SetPropertiesRules[] and the properties are set, but nothing else about setOnglet. Am I misunderstanding the way it should work ? I couldn't find any example using addSetTop, so if I have some, I would be glad to have a look at it. thanks -- Vince == 2 of 3 == Date: Tues, Dec 21 2004 5:26 pm From: "Guru" Hi, I have a database table with text and boolean. i need to show the text in a label and depending upon the boolean i need to show a check box with state off or on.

M?ller) Hello, i build a thread pool that computes some kind of jobs. The jobs are delivered by a RMI call (one call with jobarray) to the server together with a reference to the client (RMI Callback). Each job was computed by an own thread. A pool thread gets its jobs from a queue, compute it and invokes a method on the client reference. Sometimes i get a Connection refused Exception when i do the callback, but other callbacks work well. So, i enclose the callback with a synchronization block: class PoolThread extends Thread { public PoolThread(IClient client) { this.client = client; } ... run() { ... synchronized (client) { client.returnJob(job); } ... } ... } Now it works, but i do not understand why. Can anybody give me a hint? Is it because of several threads doing the callback concurrently? Does the RMI framework not handle this case? Again, everything worked well without the invokation of a callback INSIDE a thead. regards Mr. Müller ============================================================================== TOPIC: .class file includes debug info?? http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/68f1bf9ec4850ab3 ============================================================================== == 1 of 1 == Date: Tues, Dec 21 2004 4:05 am From: [EMAIL PROTECTED] Hi, I'm looking for a command-like utility which can read a .class file and tell you whether it includes debug information, i.e. whether it was built with the -g option of javac.

Amongst those gotchas and caveats, would there be a requirement to provide the client with a close() method that they have to call for the bean to know to release the connection? Or is there a mechanism for when the session expires? E.g, I am using a ConnectionPool and performing JNDI lookups by making use of Tomcat's "context". So, upon the session expiring would the context implementation be able to free the resources for reuse? Thanks.

We'll be more than glad to help you out. Sure Alin. Thanks. I'll drop by some time. I was facing a problem related to authentication previously. My test system at home doesn't belong to a domain, SQL authentication worked fine. When I uploaded onto the production server, two things: (i) I didn't upload the latest version of class A that imported static fields from a separate class B that I had modified. (ii) jTDS seems to have problems using SQL authentication when running in Tomcat's "context" when a domain is present. I solved (i) rather by chance before reading Michael's post to be clearer on the situation. (ii) was more of a hunch, that I wish had come earlier, to try and use domain=X and Windows authentication instead. Not sure if the problem is with Tomcat, jTDS or the domain policy.

When I use print(System.out) on the MyClass I get: <!DOCTYPE MyClass SYSTEM "jar:file:/D:/MyProject/lib/MyJar.jar!/MyProject/MyDTDs/MyClass_dtd.txt"> as the first line. I would like to have all of the mumbo jumbo including SYSTEM not to show up, i e I don't wont the name of the dtd to show up at all. Is there a way to accomplish this? I'm using the Oracle9 classgen.jar When I used the Oracle8 classgen.jar the SYSTEM and all the crap after didn't show up. ============================================================================== TOPIC: Setting DOCTYPE to a DOM- document http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/7f0a2e7258baad09 ============================================================================== == 1 of 1 == Date: Tues, Dec 21 2004 7:01 am From: "John C. Bollinger" All, Resolution: The method described earlier in this thread for creating a Document with DocumentType works as expected. However, that is not enough to achieve the OP's goal. (In fact, it may be orthogonal to that goal.) The OP was using a default Transformer to output a representation of his DOM document, and even though the document had a correct document type node, it was not reflected in the output. This appears to be because the data model used by XSLT does not accommodate document type declarations, and hence a Transformer object (or any other XSLT transformation mechanism) will not emit one without coaxing. One could write an appropriate document type declaration into the stylesheet as text, but that precludes using a default Transformer. There is a more flexible way: [...] import javax.xml.transform.*; import javax.xml.transform.dom.DOMSource; import org.w3c.dom.Document; import org.w3c.dom.DocumentType; [...] /** * Applies an identity XSLT transform to the provided DOM Document, * directing the result to provided Result object. If the document * contains a DocumentType node then its public and system ids are * provided as the appropriate properties of the transform, which * will generally cause a DOCTYPE declaration to be part of the * transformation result (but whether or not the provided Result * object does anything with it depends on that object). * * @param doc the DOM Document to copy * @param result the Result object that should receive the * copy * * @throws TransformerException if one occurs while obtaining an * Transformer instance or while performing the * transformation */ public void transformWithDoctype(Document doc, Result result) throws TransformerException { TransformerFactory factory = TransformerFactory.newInstance(); Transformer xformer = factory.newTransformer(); DocumentType doctype = doc.getDoctype(); if (doctype != null) { xformer.setOutputProperty( OutputKeys.DOCTYPE_PUBLIC, doctype.getPublicId()); xformer.setOutputProperty( OutputKeys.DOCTYPE_SYSTEM, doctype.getSystemId()); } /* * Note: the default output method is used (either "xml" or * "html", depending on the document). See chapter 16 of the * XSLT spec for the details. */ xformer.transform(new DOMSource(doc), result); } [...] This should also be expressible directly in XSLT.
