Question

我得到了“java.lang.ClassNotFoundException：org.jnp.interfaces.NamingContextFac “运行我的打包的ejb3 swing客户端jar时出错”。这是堆栈跟踪。

以下是我打包的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

从我的jar中显示内容： -

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classpath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？

感谢。

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不能包含* {JAR清单类路径的Here is the tutorial。
