Compiler Compliance

Im looking for answers/references on JVM performance regarding the latest Java v6 performance benchmarks. Specifically if i compile with the Java v6 compiler setting to Java v5 compliance and running on the v6 VM what am I getting in terms of the marketed performance blow-out of the v6 VM? Does the bytecode compilation drastically make a difference?

Installing a newer version of eclipse will solve your issue.

Eclipse: can't set compiler compliance level to 6.0

hello!
i have installed the following packages:
local/jdk 6u3-1
Sun's Java Development Kit
local/jdk 6u3-1
Sun's Java Development Kit
local/eclipse 3.3.1.1-1
Eclipse IDE development platform
java -version says:
java version "1.6.0_03"
Java(TM) SE Runtime Environment (build 1.6.0_03-b05)
Java HotSpot(TM) Client VM (build 1.6.0_03-b05, mixed mode)
but i cannot set the jdk compiler compliance level to 6.0! when i select it, eclipse says, that the installed jre does not support the compliance level of 1.6.
my jre definition in eclipse:
java | /opt/java | standard vm
what is the problem?
thanks, mfg iggy

How to make compiler do inline optimization in WTK?

Hello:
I'm a freshman in WTK. I found that my project is running very slow, so I wrote the following test to find the time cost of function call. I found that in this test, it spent 94ms, 1076ms and 2016ms in simulator, for 0, 1, and 2 function calls in each cycle (300,000 times).
By this result, I think function call may be very expensive and may became the bottleneck of performance in my project.
public static runTest(){
        long i = 0;
        long j = 0;
        long begin = System.currentTimeMillis();
        int times = 300000;
        for (i = 0; i < times ; i++){
            j = j + i;
        long end = System.currentTimeMillis();
        System.out.println("The result no call is " + (end - begin) );
        begin = System.currentTimeMillis();
        for (i = 0; i < times ; i++){
            j += set(i);
        end =System.currentTimeMillis();
        System.out.println("The result 1 call is " + (end - begin) );
        begin = System.currentTimeMillis();
        for (i = 0; i < times ; i++){
            j += set2(i);
        end = System.currentTimeMillis();
        System.out.println("The result 2 call is " + (end - begin) );
private static long set2(long i) {
     return set(i);
private static long set(long i) {
        return i;
}I work in eclipse ,and make sure i've checked "Inline finally blocks" check box.
I also run the same code in pc, and find the function call may have been optimized to "inline" by compiler (The times changed to 300,000,000, and result is 2016ms, 2281ms, and 2266ms), i also make sure changed the "compiler compliance level" to 1.3
In an ideal situation, the compiler can find "set(i)" is exactly "i" and change all"set(i)" to "i";
I wonder if the compiler can change some function to such "inline" in WTK. I don't know how compiler works in WTK, but as a freshman in WTK, i think there may have some optimization option i don't know. Can someone tell me how to make compile do this stuff?
Thx a lot!

...javac make something inline while WTK not...I doubt this. I think that code that was inlined by javac, will remain inlined when executed by WTK. You can check that in more details at compiler forum if needed. Javac remains the same, inlines are there - I don't think this changes.
What WTK probably can (and maybe even should) change is *hotspot* optimization settings when it emulates execution of MIDlets by real device.
As for your problem, could it be described as follows: MIDlets run slower than you'd expect of a typical desktop Java applications?
If yes then WTK User Guide seem to have an explanation for that: +"...Compared to the desktop-based emulator, a real MIDP device usually has a slower processor, less memory, and a slower network connection, and might have a different type of display. The Sun Java Wireless Toolkit for CLDC enables you to simulate the constrained environment of a real device..."+ (quoted from chapter Adjusting Emulator Performance). To me this reads like WTK forces Java machine to slow down execution of MIDlets in order to make it feel closer to a typical mobile device.

Simple ArrayList declaration will NOT compile in Eclipse

For some reason I can't get the following line of code to compile in eclipse, even though the exact same code compiles in NetBeans.
I'm trying to work on my program at school and they don't have Netbeans installed they only have Eclipse so I have to work with it instead.
Anyway, here's the line, it's a simple arraylist declaration:
ArrayList<Integer> list = new ArrayList<Integer>();I''ve got java.util.ArrayList imported.
There error I get is the following:
"Syntax error on token '<', invalid assignment operator.
Can anyone clear this up for me, I've been searching and I've basically wasted a good half-hour without even touching my damn program.

endasil wrote:
well, to go higher than 1.4 you'd need a JDK that is higher than 1.4. It really has nothing to do with eclipse, and if you don't have a 1.5 jdk installed, NetBeans will have the same problem.Nonsense. Eclipse has it's own compiler, your JDK is irrelevant.
Go to Window->Preferences->Java->Compiler and change the compiler compliance setting to 5.0 or higher. Your JRE will need to match, but the JDK need not even be installed

Upgraded to ubuntu 7.04 now jeclipse wont compile

i just upgraded to ubuntu 7.04 now when i try to compile

I have the same problem. I do not know for sure if this is what caused it but it kept reminding me to upgrade itunes so i did. Now my shuffle doesn't show up on my computer or in itunes, and there are NO songs on it. I had to restore my ipod but it said there was an error and it never finished and now it doesn't show up in itunes or windows.I plugged this into another computer but it doesn't load on that computer either. a green light comes on and blinks slowly. I have no idea whats wrong.

Problem with ' as a queryString in jsp

Hi All,
I am trying to send a value that I retrieved from the database as a queryString to other jsp. My String has special characters encoded.
When I am using the encoded in the code given below I get nothing
../common/displayMessage.do?displayMessage=<bean:write name="article" property="errorMessage"/>&article=<bean:write name="article" property="article"/>'Here my errorMessage contains something like Data map dosn (&#39 ;)t contain article info.&article=zta-0016
Special character encoding for '
How can I pass this value as a queryString?
--Any Help appreciated.

The "Compiler compliance level" is set to 5.0
I am using WebSphere v6.1 to deploy my web application.
I have no problem to create a generic ArrayList in JSP. The problem occurs when I try to cast a object which I know and have checked is a generic ArrayList.
First I check if the object is an instance of ArrayList. Then I check if the content of that ArrayList is an instance of my generic object. So I have taken every step to assure that it is what it is supposed to be.

Packet does not exist

Hello,
I am developing a WebDynpro application with Java 1.5 and NWDS 7.1. When I use external jars in the project build path I get build errors that say that the packet ...does not exist and cannot read symbol...Same thing was working smoothly with NWDS 7.0 java 1.4.
Please help!

Hi,
You can try to change your compliance level to another value:
Windows, Preferences, Java, Compiler, Compliance and classfiles.
Good luck,

MQ Adapter does not clear the rejected message from the queue

Hi All,
I'm using a MQ Adapter to fetch the message from the queue without any Backout queue configured. However, whenever there is any bad structured message found in the queue, MQ adapter rejects the message and moves the message to the rejmsg folder but does not clear it off the queue, as a result of which it keeps retrying the same hence, filling the logs and the physical memory. Somehow we do not have any backout queue configured so I can move the message to blackout queue. I have tried configuring the jca retry properties and global jca retry as well but to no avail.
- Is it not the default behaviour of MQ Adapter to remove the rejected message from the queue irrespective of Backout queue is configured or not? The same behaviour working well with the JMS and File Adapter though.
- Is there any way I can make MQ Adapter delete the message from that queue once it is rejected?

Urgent Help on Smart Card

Hi Friends
I have a javacard application which write and reads to/from the smartcard.My card supports Javacard 2.2.1 and GP 2.1.1 ,but from my experience it seems no supporting GP( it is not working GPShell sowing 6d00 error and also giving error under mode_211)
I converted my class file to a cap file .I was using Netbeans.Now i changed to Eclipse (galileo_jee) with Eclipsejcde plugin.I can convert to cap file from eclipse.I use compiler options as :
Compiler Compliance level 1.3
Source code compatibility 1.3
Generated .class file compatibilty 1.1
We can convert to a cap file through eclipse .I can run GPShell script (Ant script) using Eclipse and load the cap file to the smart card, but when i ran the following script .I am getting 6d00 error .
So I moved to Smart card shell(SC Shell):
It contains some javascript function to install the cap file to smart acrd and read some messages from FORUM that some peoples have successfully installed using Smart Card Shell.When i tried to install my cap file it is loading the file to smart card(I am able to see) ,but giving an error message at the end of install method as 6A80.The APDU trace i have pasted next message.Continue....

Thnx for your help.
Best regards.

Hello Decio Junior,
Actually yes, I resolved my problem.
I'm developing an EJB 3.0 project. I'm using NWDS 7.2 and JDK 1.6 as I said.
The problem is that my server was using JDK 1.4 and that was the problem.
EJB 1.1 and 2.1 need ejb-jar.xml but EJB 3.0 use the annotations instead.
Check your server JDK Version. It should be JDK 1.5 or higher.
Something else that you should check, in your project properties :
In the Build PATH : Use JDK 1.5
In the Java Compiler : Set the java compiler compliance level to 1.6 and check use default compliance settings
Hope it would help.
If you need more explanations, I'm here
Good luck.

hi,
you may get some idea from below lines
I changed the compiler complience level to 1.4 and deployed the application using jdk1.4. However the error was still there. When basis team checked the development config for PCUI_GP, it was sitting on SP03 which they then updated and the problem was fixed. Now I am getting a java.lang.UnsupportedClassVersionError on a different wd componet.
Thanks !

My first roadblocks in bean culture

I was trying to follow the how to make a bean instructions
http://sheikyerbouti.developpez.com/forms-pjc-bean/first-bean/first_bean.pdf
but I got bogged down here:
A Javabean source code ‘s skeleton (bean_template.txt) is provided with the samples to help you to quickly start
a new PJC/Javabean class.
• Open the bean_template.txt file provided with the samples, then copy the content in the new
GetCanvasProp.java window
What samples?
I think the url was supposed to be this but that no longer exists
http://www.oracle.com/us/technology/sample_code/products/forms/index.html
BTW I note that jdeveloper 11.1.1.2 uses weblogic 10.3.5 in case anyone was harboring wishes of less weblogic's on their system. Afraid not!
This discussion of bean construction doesn't address the samples, and uses eclipse but brings up the question of "compiler compliance
level". How do we find out the compiler compliance level of any forms version? (I'm trying to use 11.1.1.4)

UnsupportedClassVersionError in WASD

I am creating a simple java project in WASD (WebSphere Studio Application Developer Version: 5.1.1 )
but just changing compiler compliance level to 1.4 from 1.3 .
when I run a class it gives me UnsupportedClassVersionError
I don't know what is the problem ?
pls help

Having same problem as mentioned in this thread only getting it when try to run the demo webDynpro apps provided with NWDS.
Root Cause
The initial exception that caused the request to fail, was:
java.lang.UnsupportedClassVersionError: Bad version number in .class file
at java.lang.ClassLoader.defineClass1(Native Method)
After 3 installs now with different JDK's last was JDK 1_5_15 .. can't find update 12 anywhere as perscribed in earlier threads. Anyone figure out a way to resolve this without have to play shell games with JDK's. Speaking from new SAP Netweaver Guy considering jumping from ledge.
Thanks.

Eclips使用秘技(绝对经典)zt

前言：
本来我都是使用JBuilderX当主力IDE、但使用了Eclipse后
发现...Eclipse原来也这么好用...渐渐的就爱上了它......
Eclipse优点：免费、程序代码排版功能、有中文化包、可增
设许多功能强大的外挂、支持多种操作系统(Windows、
Linux、Solaris、Mac OSX)..等等。
开此篇讨论串的目的，是希望能将Eclipse的一些使用技巧集
合起来...欢迎大家继续补充下去...由于Eclipse的版本众多
，希望补充的先进们能顺便说明一下您所使用的版本～
Eclipse网站：http://www.eclipse.org/
Eclipse中文化教学：JavaWorld站内文章参考
(使用版本：Eclipse 2.1.2 Release + 中文化)
热键篇：
Template：Alt + /
修改处：窗口->喜好设定->工作台->按键->编辑->内容辅助。
个人习惯：Shift+SPACE(空白)。
简易说明：编辑程序代码时，打sysout +Template启动键，就
会自动出现：System.out.println(); 。
设定Template的格式：窗口->喜好设定->Java->编辑器->模板。
程序代码自动排版：Ctrl+Shift+F
修改处：窗口->喜好设定->工作台->按键->程序代码->格式。
个人习惯：Alt+Z。
自动排版设定：窗口->喜好设定->Java->程序代码格式制作程序。
样式页面->将插入tab(而非空格键)以内缩，该选项取消勾选
，下面空格数目填4，这样在自动编排时会以空格4作缩排。
快速执行程序：Ctrl + F11
个人习惯：ALT+X
修改处：窗口->喜好设定->工作台->按键->执行->启动前一次的启动作业。
简易说明：第一次执行时，它会询问您执行模式，
设置好后，以后只要按这个热键，它就会快速执行。
<ALT+Z(排版完)、ATL+X(执行)>..我觉得很顺手^___^
自动汇入所需要的类别：Ctrl+Shift+O
简易说明：
假设我们没有Import任何类别时，当我们在程序里打入：
BufferedReader buf =
new BufferedReader(new InputStreamReader(System.in));
此时Eclipse会警示说没有汇入类别，这时我们只要按下Ctrl+Shift+O
，它就会自动帮我们Import类别。
查看使用类别的原始码：Ctrl+鼠标左键点击
简易说明：可以看到您所使用类别的原始码。
将选取的文字批注起来：Ctrl+/
简易说明：Debug时很方便。
修改处：窗口->喜好设定->工作台->按键->程序代码->批注
视景切换：Ctrl+F8
个人习惯：Alt+S。
修改处：窗口->喜好设定->工作台->按键->窗口->下一个视景。
简易说明：可以方便我们快速切换编辑、除错等视景。
密技篇：
一套Eclipse可同时切换，英文、繁体、简体显示：
1.首先要先安装完中文化包。
2.在桌面的快捷方式后面加上参数即可，
英文-> -nl "zh_US"
繁体-> -nl "zh_TW"
简体-> -nl "zh_CN"。
(其它语系以此类推)
像我2.1.2中文化后，我在我桌面的Eclipse快捷方式加入参数-n1 "zh_US"。
"C:\Program Files\eclipse\eclipse.exe" -n "zh_US"
接口就会变回英文语系噜。
利用Eclipse，在Word编辑文书时可不必将程序代码重新编排：
将Eclipse程序编辑区的程序代码整个复制下来(Ctrl+C)，直接贴(Ctrl+V)到
Word或WordPad上，您将会发现在Word里的程序代码格式，跟Eclipse
所设定的完全一样，包括字型、缩排、关键词颜色。我曾试过JBuilder
、GEL、NetBeans...使用复制贴上时，只有缩排格式一样，字型、颜
色等都不会改变。
外挂篇：
外挂安装：将外挂包下载回来后，将其解压缩后，您会发现features、
plugins这2个数据夹，将里面的东西都复制或移动到Eclipse的features
、plugins数据夹内后，重新启动Eclipse即可。
让Eclipse可以像JBuilderX一样使用拖拉方式建构GUI的外挂：
1.Jigloo SWT/Swing GUI Builder ：
http://cloudgarden.com/jigloo/index.html
下载此版本：Jigloo plugin for Eclipse (using Java 1.4 or 1.5)
安装后即可由档案->新建->其它->GUI Form选取要建构的GUI类型。
2.Eclipse Visual Editor Project：
http://www.eclipse.org/vep/
点选下方Download Page，再点选Latest Release 0.5.0进入下载。
除了VE-runtime-0.5.0.zip要下载外，以下这2个也要：
EMF build 1.1.1: (build page) (download zip)
GEF Build 2.1.2: (build page) (download zip)
3.0 M8版本，请下载：
EMF build I200403250631
GEF Build I20040330
VE-runtime-1.0M1
安装成功后，便可由File->New->Visual Class开始UI设计。
安装成功后，即可由新建->Java->AWT与Swing里选择
所要建构的GUI类型开始进行设计。VE必须配合着对应
版本，才能正常使用，否则即使安装成功，使用上仍会
有问题。
使用Eclipse来开发JSP程序：
外挂名称：lomboz(下载页面)
http://forge.objectweb.org/project/showfiles.php?group_id=97
请选择适合自己版本的lomboz下载，lomboz.212.p1.zip表示2.1.2版，
lomboz.3m7.zip表示M7版本....以此类推。
lomboz安装以及设置教学：
Eclipse开发JSP-教学文件
Java转exe篇：
实现方式：Eclipse搭配JSmooth(免费)。
1.先由Eclipse制作包含Manifest的JAR。
制作教学
2.使用JSmooth将做好的JAR包装成EXE。
JSmooth下载页面：
http://jsmooth.sourceforge.net/index.php
3.制作完成的exe文件，可在有装置JRE的Windows上执行。
Eclipse-Java编辑器最佳设定：
编辑器字型设定：工作台->字型->Java编辑器文字字型。
(建议设定Courier New -regular 10)
编辑器相关设定：窗口->喜好设定->Java->编辑器
外观：显示行号、强调对称显示的方括号、强调显示现行行、
显示打印边距，将其勾选，Tab宽度设4，打印编距字段设80。
程序代码协助：采预设即可。
语法：可设定关键词、字符串等等的显示颜色。
附注：采预设即可。
输入：全部字段都勾选。
浮动说明：采预设即可。
导览：采预设即可。
使自动排版排出来的效果，最符合Java设计惯例的设定：
自动排版设定：窗口->喜好设定->Java->程序代码制作格式。
换行：全部不勾选。
分行：行长度上限设：80。
样式：只将强制转型后插入空白勾选。
内缩空格数目：设为4。

补充：(于Eclipse使用assertion机制)
Eclipse版本：2.1.3 release。
JDK1.4版新加入的assertion机制(关键词：assert)，由于JDK1.4编译器
预设是兼容1.3，所以要使用assert必须在编译时加上-source 1.4的参数。
C:\>javac -source 1.4 XXX.java
执行时则必须加-ea 或-enableassertions参数启动。
C:\>java -ea XXX
如要在Eclipse中使用assertion机制，请作以下设定：
设定一：(编译设定)
Windows->Preferance->Java->Compiler->Compliance and Classfiles
页面。将..JDK Compliance level->Compiler compliance level调成1.4。
设定二：(执行设定)
Run->Run->(x)=Arguments页面，在VM arguments加入-da参数，按下
Run button便可看到启动assertion后的执行结果。
(Eclipse 2.1.3 release + assertion测试)
<assert判别为false，所以show出AssertionError>
新版(m8+)的eclipse可以设vm arguments
另外提供一种设法，是在eclipse启动时加入vm arguments(跟加大eclipse预设内存大小的方式一样)
这样就不用每次run都得需去设vm arguments

其实很多功能JBuilder中也都有，我现在用惯了JBuilder，反而觉得eclipse不方便，习惯而已。不过eclipse是免费的！
