运行打包的 ejb3 swing 客户端 jar 时出现“java.lang.ClassNotFoundException: org.jnp.interfaces.NamingContextFac tory”错误。这是堆栈跟踪。

这是我打包的 Swing 客户端 Jar 内容：-

MetaDB-Client.jar
  \net\.. - contains class files(from both client and server)
  META-INF
    MANIFEST.MF
  jndi.properties

这是我的 jndi.properties：-

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
java.naming.provider.url=localhost:1099

这是我的 MANIFEST.MF：-

Manifest-Version: 1.0
Main-Class: net.massmatrix.metadb.ui.MainFrame
Class-Path: jbossall-client.jar

我的罐子里的清单内容：-

Manifest-Version: 1.0
Created-By: 1.6.0_18 (Sun Microsystems Inc.)
Main-Class: net.massmatrix.metadb.ui.MainFrame

用于创建 jar 的命令：-

jar cfm MetaDB-Client.jar MANIFEST.MF net\* jndi.properties

用于运行 jar 的命令：-

java -jar MetaDB-Client.jar

我的类路径中有 jbossall-client.jar

G:\Courses\OSUMC\Installables\June 5\New>echo %CLASSPATH%
.;G:\Courses\OSUMC\WORK\Software - New\jboss-5.0.1.GA\client

我还缺少什么？

谢谢。

您所要做的就是将 jbossall-client.jar 库添加到客户端 lib 文件夹中。
MANIFEST 中的 ClassPath 中不能有 *。
这是 JAR 清单类路径的教程。
