我有一个Eclipse应用程序,为此我创建了用于生成jnlp文件的功能。 我用maven tycho构建了应用程序,用于体系结构x86和x86_64。
当我尝试为应用程序启动jnlp时,我看到所有资源都已下载,但应用程序无法启动。如果我尝试在broswer中打开它,它就会启动。我检查了第一个案例的日志,我得到了以下内容:

以下是生成资源的pom的一部分:

<groupId>org.eclipse.tycho</groupId>
<artifactId>target-platform-configuration</artifactId>
<version>${tycho-version}</version>
<configuration>
<resolver>p2</resolver>
<ignoreTychoRepositories>true</ignoreTychoRepositories>
<environments>
<environment>
<os>win32</os>
<ws>win32</ws>
<arch>x86</arch>
</environment>
<environment>
<os>win32</os>
<ws>win32</ws>
<arch>x86_64</arch>
</environment>
</environments>
</configuration>
</plugin>
我确实检查过资源是否在jnlp文件中引用:
<resources os="Windows" arch="x86">
<jar href="plugins/org.eclipse.swt.win32.win32.x86_3.7.2.v3740f.jar"/>
我还检查了缓存并下载了资源。
我无法找到应用程序无法启动Java Web Start的原因,因为在浏览器中直接启动应用程序时没有任何问题。
感谢任何帮助!
答案 0 :(得分:0)
我的应用程序出现了同样的错误。该项目使用buckminster构建,但也适用于x86和x86_64。
您的应用程序确实是通过浏览器启动的,因为这是一个32位应用程序,它将调用您的webstart作为32位应用程序。
通过Windows资源管理器启动应用程序,启动64位应用程序,这会遇到麻烦。
以下是适合我的解决方案:
编辑包含功能的jnlp文件:
修改(原始的jnlp文件,它不起作用)
...
</resources>
<resources os="Windows" arch="x86">
<jar href="plugins/org.eclipse.swt.win32.win32.x86_3.7.0.v3735b.jar"/>
<jar href="plugins/org.eclipse.core.filesystem.win32.x86_1.1.300.v20110423-0524.jar"/>

</resources>
into(新的jnlp文件,应该可以工作)
...
<resources os="Windows" arch="x86">
<jar href="plugins/org.eclipse.swt.win32.win32.x86_3.7.0.v3735b.jar"/>

换句话说:删除arch =“x86_64”过滤器。
我认为这是昼夜平分点发射器的错误。但它的真正原因对我来说是个秘密。
P.S:仅为org.eclipse.swt.win32.win32.x86_64捆绑包删除arch-filter也适用。
