使用Java Web Start在Mac上启动SWT [英] Launching SWT on Mac using Java Web Start
问题描述
目标:使用Java 7在Mac上启动SWT Web Start应用程序
Goal: Launch SWT Web Start application on Mac using Java 7
为了在Mac OS X上运行SWT RCP应用程序，有据可查，有必要包含
In order to run an SWT RCP application on Mac OS X, it is well documented that it is necessary to include -XstartOnFirstThread as part of the Java Virtual Machine arguments.
不幸的是，Java Web Start似乎正在删除该参数.查看Java Web Start的详细跟踪日志:
Unfortunately, Java Web Start seems to be deleting this argument. Looking at Java Web Start’s detailed tracing logs:
temp: returning LaunchDesc from XMLFormat.parse():
<jnlp spec="1.0+" codebase="..." href="...">
<information> ...
<resources>
<java java-vm-args="-XstartOnFirstThread -Xms1024m" version="1.6+"/> ...
因此，Web Start成功接收了XstartOnFirstThread参数.
So Web Start is successfully receiving the XstartOnFirstThread parameter.
及以后

类似地，在日志中的其他地方:
Similarly, elsewhere in the log:
Selected JVMParam: [JVMParameters: isSecure: false, args: -XstartOnFirstThread -Xms1024m -Djnlp.serverIP=... -Djnlp.eclipse.product=... -Djnlp.debugLevel=1]
Running JVMParam: [JVMParameters: isSecure: true, args: "-Xms1024m -Djnlp.serverIP=... -Djnlp.eclipse.product=... -Djnlp.debugLevel=1"]
请注意已正确标识了startOnFirstThread，但未在下一处理阶段传递它.也许它没有被识别为'isSecure:true'?
Notice that startOnFirstThread is correctly identified, but then not passed along in the next processing stage. Perhaps it's not recognized as 'isSecure: true'?
...最后我感到恐惧:
... and in the end I get the dreaded:
OS X Detected...
***WARNING: Display must be created on main thread due to Cocoa restrictions.
org.eclipse.swt.SWTException: Invalid thread access
at org.eclipse.swt.SWT.error(SWT.java:4361)
Web Start正确解析-XstartOnFirstThread和-Xms1024m，但仅选择传递-Xms1024m而不是-XstartOnFirstThread.
Web Start correctly parses -XstartOnFirstThread and -Xms1024m but only chooses to pass on -Xms1024m and NOT -XstartOnFirstThread.
同样，如果在Web Start开始加载应用程序的几秒钟内执行ps aux | grep ms1024m，我将得到:
In the same vein, if I execute ps aux | grep ms1024m for the few seconds that Web Start begins to load the application, I get:

同样，使用Xms1024m，但不使用XstartOnFirstThread.
Again, Xms1024m is used, but not XstartOnFirstThread.
(请注意，一些标识信息已从此处发布的日志中删除，但这不应影响分析).
(Note a number of pieces of identifying information were removed from the logs posted here, but this should not affect the analysis).
我还确认了将相关文件从服务器复制到本地计算机并通过java -XstartOnFirstThread...运行该应用程序没有问题.
I have also confirmed that copying the relevant files from the server to my local computer and running the application via java -XstartOnFirstThread... works without a problem.
如何使用Java 7在Mac上启动SWT Web Start应用程序?如何使startOnFirstThread能够被Java 7成功处理?在SWT Mac泥潭附近还有另一种方法吗?
How can I launch an SWT Web Start application on Mac using Java 7? How can I get startOnFirstThread to be successfully processed by Java 7? Is there another way around the SWT Mac quagmire?

推荐答案
您是否尝试过使该参数成为受信任的参数?我还没有尝试过.但是请在Java小程序期间检查启动时，正在运行的JVM args与安全子集匹配"是什么?是什么意思?
Have you tried to make that parameter a trusted one? I have not tried it. But please check During Java applet startup, what does "Running JVM args match the secure subset" mean?
这篇关于使用Java Web Start在Mac上启动SWT的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
