When you try to access the zeroth element of that non-existent array, you get a NullPointerException. > imgs[0] = getImage(image[0]); > mt.addImage(imgs[0], 0); > [...] > imgs[5] = getImage(image[5]); Once you solve the NullPointerException, your next problem will be the ArrayIndexOutOfBoundsException you get when you try to access the sixth element of this five-element array ... By the way, have you ever heard of something called a "loop?" The code you're using for all ten of these images differs only in the URL strings and in the array indices. Why not just make an array of the strings and then write a loop that repeats the same code ten times, once for each string? It's not only boring to write the exact same code ten times in a row, but you'll find that it's also error-prone. -- [EMAIL PROTECTED] == 3 of 4 == Date: Wed, Dec 1 2004 11:22 pm From: Andrew Thompson On Wed, 01 Dec 2004 22:40:54 GMT, Emilie Dorchies via JavaKB.com wrote: > The following code is ought to init my applet displaying a > solution to the CIgarette Smokers Concurrency Problem.

Usually I recommend that folks set their news-client to do it for them, but I notice you are using a web-based interface to Usenet, so you will need to do it manually. > But it returns ...

Anyone 's got a workaround? Sensible code should do the trick, no 'workarounds' required. But before we get to a solution there are some (OK many) things that need to be cleared up. - You are posting to a group for advanced questions about Java, whereas it is apparent that you are just learning, so a better group to post to for the moment is <http://www.physci.org/codes/javafaq.jsp#cljh> On your web-based interface to usenet, it is referred to as 'First Aid'. - Don't mix swing and the AWT, they do not play well together. - Please post an SSCCE[1], rather than 102 lines of code that do not compile, due to.. - lack of import statements and a closing '}' - Missing two classes, 'Lock' and 'CigarCanvas' [1] <http://www.physci.org/codes/sscce.jsp> - When discussing applet problems in particular, always mention what OS and version, browser and version, Java maker and version. The last can be answered here. <http://www.physci.org/pc/property.jsp?prop=java.version+java.vendor> - As mentioned in the SSCCE document, when dealing with applets, upload the applet (broken or whatever) and source (and images) to a free web-server like GeoCities so that people who are helping you can see it break for themselves. Link to the code from the applet page. - Read the FAQ referenced above, from start to finish. It mentions both applets (many times) and how to find resources. See you over on 'First Aid' with those things fixed up and we should be able to fix the problem pronto.

I find Borland's OptimizeIt to be an excellent profiler of memory and cpu. I find it easy to identify memory leaks. It's about $800 2. Recently, I've tried Enerjy(enerjy.com) cpu and memory profiler. They plug into your IDE so you can profile while you code. They're nice tools and cheaper. 3. JRockit's JRA tool has good output and a more runtime environment orientation. For example, it clearly states heap usage, number of garbage collections, etc. But the profiling is not as strong. It's free at http://e-docs.bea.com/wljrockit 1 & 2 both offer free evals.

Thanks, Neetij == 2 of 2 == Date: Wed, Dec 1 2004 5:17 pm From: "[EMAIL PROTECTED]" [crosspost to comp.lang.java,comp.lang.java.programmer,comp.lang.java.beans] Greetings All. I'm trying out XMLBeans 1.0.3 (in Windows environment). To test, I am using code from this article - Programming with XMLBeans (http://www-106.ibm.com/developerworks/xml/library/x-beans1/). However, I have trouble compiling the XSD file using the command: scomp -out automobile-policy.jar automobile-policy.xsd I get the following errors: Time to build schema type system: 1.892 seconds Time to generate code: 0.331 seconds 'javac' is required on the path. java.io.IOException: CreateProcess: D:\www\testbed\javac @C:\DOCUME~1\jay\LOCALS~1\Temp\javac15795 error=2 null java.io.IOException: CreateProcess: D:\www\testbed\javac @C:\DOCUME~1\jay\LOCALS~1\Temp\javac15795 error=2 at java.lang.Win32Process.create(Native Method) at java.lang.Win32Process.<init>(Unknown Source) at java.lang.Runtime.execInternal(Native Method) at java.lang.Runtime.exec(Unknown Source) at java.lang.Runtime.exec(Unknown Source) at java.lang.Runtime.exec(Unknown Source) at org.apache.xmlbeans.impl.tool.CodeGenUtil.externalCompile(CodeGenUtil.java:218) at org.apache.xmlbeans.impl.tool.SchemaCompiler.compile(SchemaCompiler.java:815) at org.apache.xmlbeans.impl.tool.SchemaCompiler.main(SchemaCompiler.java:264) BUILD FAILED I have tried using '-verbose' and '-compiler' options as well but continue to get errors. Apache's XMLBeansv1 Wiki (http://wiki.apache.org/xmlbeans/XmlBeansV1Faq#scompFindingJavac) gives a solution to the first error - changing the location of %JAVA_HOME% in the path (move it higher up). This does not solve the problem as I still have to specify the compiler location. What gives? My updated command is: scomp -compiler C:\Java\j2sdk1.4.2_05\bin\javac -out automobile-policy.jar automobile-policy.xsd I now get the following errors: Time to build schema type system: 1.893 seconds Time to generate code: 0.34 seconds Time to compile code: 2.274 seconds java.io.IOException: CreateProcess: D:\www\testbed\jar cf D:\www\testbed\automobile-policy.jar -C C:\DOCUME~1\jay\LOCALS~1\Temp\xbean30916.d\classes . error=2 at java.lang.Win32Process.create(Native Method) at java.lang.Win32Process.<init>(Unknown Source) at java.lang.Runtime.execInternal(Native Method) at java.lang.Runtime.exec(Unknown Source) at java.lang.Runtime.exec(Unknown Source) at java.lang.Runtime.exec(Unknown Source) at org.apache.xmlbeans.impl.tool.CodeGenUtil.externalJar(CodeGenUtil.java:304) at org.apache.xmlbeans.impl.tool.SchemaCompiler.compile(SchemaCompiler.java:825) at org.apache.xmlbeans.impl.tool.SchemaCompiler.main(SchemaCompiler.java:264) BUILD FAILED I cannot figure out what the problem is here. I haven't found any solutions online either. Any ideas as to how I can remedy this situation?

The problem right now is testing it in Mac. I only have an old Mac Performa with OS8, and my Mac isn't reading it right. Anyone know how to use a Java console program in pre-OSX Macs? When I double click on the jar file it launches an editor now, does anyone know how to launch it as a console application? I have the Java Runtime Engine installed. I believe want to associate the jar files with the Java Runtime Engine in OS8...does anyone know how to do that with a Mac? -- Robert Pearson http://www.rspearson.com/ ParaMind Brainstorming Software http://www.paramind.net ============================================================================== TOPIC: Java-Query http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/802e1612aa3ef8f4 ============================================================================== == 1 of 1 == Date: Wed, Dec 1 2004 10:00 pm From: "Hal Rosser" "Anil" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > Whats the particular use of method overloading It depends on the particular method, but mostly its to confuse Cobol programmers.

As these tablespaces are growing, I'm near the 2Gig limit imposed by Java 1.4.2_06. I am investigating if I can alleviate this limit by using Java 5.0 with 64 bit Linux. My question is as follows: what is the largest ByteBuffer I can allocate in Java 5.0 64 bit Linux edition? I know that Linux 64 bit edition supports 512G virtual space per process. Can Java 5.0 utilize all 512G virtual space, and if so, how much for ByteBuffers ? If Java 5.0 can allocate only 2G ByteBuffers, can it allocate a pool of ByteBuffers, whose sum is 512G ?

This is a HUGE subject area so I dont know why you cant find much.
