  • Apache BeanUtils.copyProperties is spilling too much log

    - by Ravi Gupta
    How can I switch off logging for BeanUtils.copyProperties ? It creates way too much logs and hampers the log file readability. Thanks heaps.. Sample code BeanUtils.copyProperties(someDataobject,someActionForm); In the log I see hunders of lines like below EBUG org.apache.commons.beanutils.PropertyUtils - setSimpleProperty: Invoking method public void someMethod(java.lang.String) with value null (class ) 2010-03-23 18:53:23,134 DEBUG org.apache.commons.beanutils.BeanUtils - copyProperty(someActionForm@13e38a7, someValue, )

    - by user267581
    When using ANT to build my Java application I keep getting this error. I have tried multiple times to use SQLJDBC.JAR and SQLJDBC4.JAR but continually receive this error message. I am completely stumpped why this error is received even after upgrading to sqljdbc4.jar. [javadoc] java.lang.UnsupportedOperationException: Java Runtime Environment (JRE) version 1.6 is not supported by this driver. Use the sqljdbc4.jar class library, which provides support for JDBC 4.0.

  • What's the correct way to read an inputStream into a node property in JCR 2?

    - by Stuart
    In JCR 1 you could do: final InputStream in = zip.getInputStream(zip.getEntry(zipEntryName)); node.setProperty(JcrConstants.JCR_CONTENT, in); But that's deprecated in JCR 2 as detailed at http://www.day.com/maven/jsr170/javadocs/jcr-2.0/javax/jcr/Node.html#setProperty%28java.lang.String,%20java.io.InputStream%29 That says I should be using node.setProperty(String, Binary) but I don't see any way to turn my inputStream into a Binary. Can anyone point me to docs or example code for this?

If anyone has seen this error before and could offer some help, I would be obliged.

  • How can I prevent PermGen space errors in Netbeans?

    - by DR
    Every 15-30 minutes Netbeans shows a "java.lang.OutOfMemoryError: PermGen space". From what I learned from Google this seems to be related to classloader leaks or memory leaks in general. Unfortunatly all suggestions I found were related to application servers and I have no idea to adapted them to Netbeans. (I'm not even sure it's the same problem) Is it a problem in my application? How can I find the source?

  • Wanted: a very simple java RegExp API

    - by itsadok
    I'm tired of writing Pattern p = Pattern.compile(... Matcher m = p.matcher(str); if (m.find()) { ... Over and over again in my code. I was going to write a helper class to make it neater, but I then I wondered: is there a library that tries to provide a simpler facade for Regular Expressions in Java? I'm thinking something in the style of commons-lang and Guava.

  • Why do I get a NullPointerException when initializing Spring

    - by niklassaers
    Hi guys, I've got a problem running a batch job on my server, whereas it runs fine from Eclipse on my development workstation. I've got my Spring environment set up using Roo, made an entity, and make a batch that does some work, and test it well on my develompent box. I initialize my context and do the work, but when I run my batch on the server, the context isn't initialized properly. Here's the code: public class TestBatch { private static ApplicationContext context; @SuppressWarnings("unchecked") public static void main(final String[] args) { context = new ClassPathXmlApplicationContext("/META-INF/spring/applicationContext.xml"); try { @SuppressWarnings("unused") TestBatch app = new TestBatch(); } catch (Exception ex) { ex.printStackTrace(); } } public void TestBatch() { /** Do Something using the context **/ } } And here's the log and exception: 2010-02-16 11:54:16,072 [main] INFO org.springframework.context.support.ClassPathXmlApplicationContext - Refreshing org.springframework.context.support.ClassPathXmlApplicationContext@6037fb1e: startup date [Tue Feb 16 11:54:16 CET 2010]; root of context hierarchy Exception in thread "main" java.lang.ExceptionInInitializerError at org.springframework.context.support.AbstractRefreshableApplicationContext.createBeanFactory(AbstractRefreshableApplicationContext.java:194) at org.springframework.context.support.AbstractRefreshableApplicationContext.refreshBeanFactory(AbstractRefreshableApplicationContext.java:127) at org.springframework.context.support.AbstractApplicationContext.obtainFreshBeanFactory(AbstractApplicationContext.java:458) at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:388) at org.springframework.context.support.ClassPathXmlApplicationContext.<init>(ClassPathXmlApplicationContext.java:139) at org.springframework.context.support.ClassPathXmlApplicationContext.<init>(ClassPathXmlApplicationContext.java:83) at tld.mydomain.myproject.batch.TestBatch.main(TestBatch.java:51) Caused by: java.lang.NullPointerException at org.springframework.beans.factory.support.DefaultListableBeanFactory.<clinit>(DefaultListableBeanFactory.java:103) ... 7 more Any idea or hints as to what's going on? My classpath is set to $PROJECTHOME/target/classes, and all my dependencies are in $PROJECTHOME/target/lib, and I execute using "export CLASSPATH=$PROJECTHOME/target/classes; java -Djava.endorsed.dirs=$PROJECTHOME/target/lib tld.mydomain.myproject.batch.TestBatch" Is there anything in my setup that looks very wrong? When I run this from Eclipse, no problems, but when I deploy it on the server where I want to run it and run it as described above, I get this problem. Because it runs from Eclipse, I believe my config files are all right, but how can I debug what's causing this? Perhaps I have some config errors or a mismatch between the server and the development workstation after all? Or is this a really weird way of saying file not found, and if so, how do I make sure it finds the correct file?? I'm really looking forward to hearing your suggestions as to how to tackle this problem. Cheers Nik

  • Correct mapping for SHChangeNotify in JNA

  • Problem running a simple EJB application

    - by Spi1988
    I am currently running a simple EJB application using a stateless Session Bean. I am working on NetBeans 6.8 with Personal Glassfish 3.0 and I have installed on my system both the Java EE and the Java SE. I don't know whether it is relevent but I am running Windows7 64-bit version. The Session Bean I implemented has just one method sayHello(); which just prints hello on the screen.
