J2EE_SERVER_WEBSPHERE

public static final int J2EE_SERVER_WEBSPHERE

Constant defining WebSphere j2ee server.

See Also:

Constant Field Values

JONAS_IDENTIFIER

public static final java.lang.String JONAS_IDENTIFIER

Constant identifying JOnAS j2ee server. There is retrieved parent of the classloader because it identify jonas server. Using just classloader there is retireved particular web server identifier (jetty, tomcat, ...). ClassLoader parent for JOnAS 4.2.3: org.objectweb.jonas_lib.loader.SimpleWebappClassLoader

Constant Field Values

JBOSS_IDENTIFIER

public static final java.lang.String JBOSS_IDENTIFIER

Constant identifying JBoss j2ee server. ClassLoader parent for JBoss 3.2.6 and 4.0.1: org.jboss.system.server.NoAnnotationURLClassLoader

See Also:

Constant Field Values

WEBLOGIC_IDENTIFIER

public static final java.lang.String WEBLOGIC_IDENTIFIER

Constant identifying WebLogic j2ee server. ClassLoader parent for BEA WebLogic 7.0 and 8.1: weblogic.utils.classloaders.GenericClassLoader

See Also:

Constant Field Values

WEBSPHERE_IDENTIFIER

public static final java.lang.String WEBSPHERE_IDENTIFIER

Constant identifying WebSphere j2ee server. ClassLoader parent for IBM WebSphere 6: com.ibm.ws.classloader.JarClassLoader

See Also:

Constant Field Values

s_iDetectedServer

protected static int s_iDetectedServer

Since J2EE server doesn't changes during execution we can cache the value for detected server.

Method Detail

getJ2EEServerType

public static int getJ2EEServerType()

Method detects and returns type of the current running j2ee server. For detecting actual running j2ee server we will use ClassLoader because it is server specific.

Returns:

int - representation of the curernt running j2ee server

detectJ2EEServerType

protected static int detectJ2EEServerType(java.lang.String strIdentifier)

Detect current running j2ee server based on the specified string because it is server specific.

Parameters:

strIdentifier - - string which should uniquely identify the AS

Returns:

int - representation of the current running j2ee server
