On Solaris 10, I'm using JDK 1.5.0_22 and when I run any of the JDK executables (javac, native2ascii, javadoc, etc) in the JDK/bin directory that require tools.jar to run, I get this error (run with and without arguments): Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/tools/javac/Main JRE executables in the bin dir...
I have created a JAR file and I want run it on a client. I have a couple of questions: How can I convert the JAR file to an EXE file? How can I encrypt the JAR file's contents? The jar file could be extracted with WinRAR and the classes could be decompiled with any Java decompiler. How can I create a installer? My clients doesn't have ...
To tell the truth, I am quite confused on all these terms (JDK/JRE/Java SDK). I am not sure what each one does. When I first started doing simple java examples in eclipse, I am pretty sure I only had the JRE, which I believed was the default java installer regular users use to be able to run java programs/applets on their system. Howev...

Now I just updated to 6u18, and I saw that it has been replaced to com.sun.xml.internal.bind.marshaller.NamespacePrefixMapper. However if I import this class and try to compile my classes, I get the error: pac...
I am using jersey for a REST WS. How do I enable jersey logs at server side? Long story: I get a clientside exception - but I don't see anything in tomcat logs [It doesn't even reach my method]. Since the stack trace is saying "toReturnValue" it did get something from server. But I don't know what the server said. Exception in thread ...
Hey! Migrating to GlassFish v3 / JDK6u18 / NB6.8 makes me a lot of headscratching, and I'm quite confused now. My project (JSF, RichFaces, Spring) works fine with GlassFish v2 + JDK6u17. I'm using the same JAR's, and the same JSF version. One of my JSP's contains a <rich:tree>, this renders just fine, but if I post the values on this p...
Was chatting to a colleague about the design of Javas libraries. I mentioned I'd always found it funny that the AWT/Swing classes called that essentially provide an Observable interface on a UI widget were actually called "listeners". Whereupon he floored me by pointing out that there would have been a name clash with java.util.Observer...
I thought this would be very easy. I downloaded the JDK, extracted src.zip, modified the JDK to fit my needs and saved the file. Now, the only thing I need to do is recompile the extracted and update src folder to a "JRE". I tried using javac, but didn't get anywhere. For example, I got the error that no source files were given. I am ob...

My runtime environment is still on JDK1.4 but I like the Solr features related to how documents are ingested and indexed. Would I be able to index my documents using Solr offline on a recent version of the JDK, copy the index over and use it in my runtime environment with an older version of the JDK? Version wise, Solr 1.4.0 uses Apach...

Hi is there a standard place for accessing empty array constants in the JDK > 1.5. When I want to do a conversion from a String Collection (e.g. ArrayList)to a String Array I find myself using my own which is defined in my own Constants class: public static final String[] EMPTY_STRING_ARRAY = new String[0]; And then in my client cod...
Hi all. I am trying to build a Hudson plugin I've modified and it requires jdk1.6. This is fine, but I don't see how I can tell maven where the different jdk is. I've found few mentions on the internet but they don't seem to apply to me. Some suggest adding some config to .m2/settings.xml but I don't have a settings.xml. Plus, I don't wa...

C:\Program Files\Java\jdk1.6.0_17\jre\bin\server is in my PATH environment variable. Does anyone know how to accomplish this? Thanks. ...
