如何从SWT应用程序运行SWT应用程序？

-1

我有两个SWT应用程序。从应用程序1，我请APP2：如何从SWT应用程序运行SWT应用程序？

Runtime.getRuntime().exec("App2.bat");

App2的是拼命地跑，但得到显示时，它抛出异常：

java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons: 
    no swt-win32-3740 in java.library.path 
    no swt-win32 in java.library.path 
    C:\Documents and Settings\Tran Dinh Thoai\.swt\lib\win32\x86\swt-win32-3740.dll: The referenced assembly is not installed on your system 
    Can't load library: C:\Documents and Settings\Tran Dinh Thoai\.swt\lib\win32\x86\swt-win32.dll

    at com.escapenotes.updater.Checker.run(Checker.java:58) 
    at com.escapenotes.updater.Runner.main(Runner.java:20)

当我打电话APP2（运行App2.bat）从命令行中，它运行但是它从app1运行时会抛出异常。我如何从app1运行app2？

这是App2.bat的内容：

@echo off 
    set JH=C:\Program Files\Java\jre6 
    set CP=C:\Data\Projects\EscapeNotes\extensions\Updater\bin 
    set XNP="%CP%";"%CP%\commons-logging-1.1.1.jar";"%CP%\aws-java-sdk-1.0.007.jar";"%CP%\commons-codec-1.4.jar";"%CP%\commons-httpclient-3.0.1.jar";"%CP%\jsoup-1.6.2.jar";"%CP%\log4j-1.2.8.jar";"%CP%\text.jar";"%CP%\jface.jar";"%CP%\jfacetext.jar";"%CP%\osgi.jar";"%CP%\runtime.jar";"%CP%\swt.jar" 
    "%JH%\bin\java.exe" -cp %XNP% com.escapenotes.updater.Runner %1

当我加入-Djava.library.path

@echo off 
set JH=C:\Program Files\Java\jre6 
set CP=C:\Data\Projects\EscapeNotes\extensions\Updater\bin 
set XNP="%CP%";"%CP%\commons-logging-1.1.1.jar";"%CP%\aws-java-sdk-1.0.007.jar";"%CP%\commons-codec-1.4.jar";"%CP%\commons-httpclient-3.0.1.jar";"%CP%\jsoup-1.6.2.jar";"%CP%\log4j-1.2.8.jar";"%CP%\text.jar";"%CP%\jface.jar";"%CP%\jfacetext.jar";"%CP%\osgi.jar";"%CP%\runtime.jar";"%CP%\swt.jar" 
"%JH%\bin\java.exe" -Djava.library.path="C:\Data\Projects\EscapeNotes\extensions\Updater\bin" -cp %XNP% com.escapenotes.updater.Runner %1

虽然有C：\数据\项目\ EscapeNotes \扩展\更新\ bin \ swt-win32-3740.dll，我得到了异常：

java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons: 
    C:\Data\Projects\EscapeNotes\extensions\Updater\bin\swt-win32-3740.dll: The referenced assembly is not installed on your system

请将“App2.bat”的内容添加到您的问题中。 – Baz

我已经添加了App2.bat的内容到我的问题 –

从异常看起来像swt-win32库没有定义java.library.path环境变量。在您的“App2.bat”中，请提供以下-D选项：

java -Djava.library.path=[path to your library]
