我也面临类似的问题:
我有TrainingDNA.jnlp用于TrainingDNA.jar。 jar和jnlp都是Linux服务器上的Tomcat Apache 6(webapps / root)的主机。 jnlp在64位Windows操作系统中启动jar文件应用程序,但是当我尝试从: 1. IE浏览器32bit操作系统,Win XP它给我错误:“找不到主类:com.sangha.gui.Main,程序会退出”,我已经启用了java控制台看输出,下面是java控制台错误:

2.从Firefox开始,java Java 6窗口出现,java控制台闪烁一秒钟。
PS:TrainingDNA.jar没有任何问题,因为如果我不使用JNLP并双击并运行它,它在32位运行正常。
以下是我的jnlp文件:
<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="1.0+" codebase="http://192.168.244.25:8080/" href="TrainingDNA.jnlp">

<jar href="TrainingDNA.jar" main="true" />
<j2se version="1.6+" />

<application-desc main-class="com.sangha.util.Relauncher" />
</jnlp>
*上面提到的主要类'Relauncher'只是应用程序的入口点,在这个类中它读取一个配置文件'relauncher.config',后者又指定应用程序的主类。配置文件的内容如下:
Class-Start: com.sangha.gui.Main
Class-Memory: 1024
Class-Arg-0: -propsResource
Class-Arg-1: /com/sangha/gui/client.cfg
Class-Arg-2: DNA.Client

答案 0 :(得分:0)
(@ akita的评论重新发布为答案,以获取一些格式)
它开始在32位Java中工作,但确实做到了:
已替换:
<resources>
<j2se version="1.6+" />
<jar href="TrainingDNA.jar" main="true" />
</resources>
具有:
<resources>
<j2se version="1.6+" java-vm-args="-Xmx1024M"/>
<jar href="TrainingDNA.jar" main="true" />
<property name="sun.java2d.noddraw" value="true"/>
</resources>
