将共享库附加到 WebSphere 应用程序的模块

Question

根据 IBM 文档，我编写了一个 jython 脚本，用于将共享库添加到现有应用程序。

# Application name
app = sys.argv[0]

dep = AdminConfig.getid('/Deployment:' + app + '/')
depObject = AdminConfig.showAttribute(dep, 'deployedObject')
classldr = AdminConfig.showAttribute(depObject, 'classloader')

for x in range(1, len(sys.argv)):
    AdminConfig.create('LibraryRef', classldr, 
                       [['libraryName', sys.argv[x]], ['sharedClassloader', 'true']])

AdminConfig.save()

不幸的是，这只是为应用程序而非模块设置共享库。我怎样才能为两者设置库？

我试图获取应用程序的模块，但无法获取它的类加载器。

顺便说一句，sharedClassloader 属性用于什么？

注意：我知道这是不好的做法，但我继承了一堆遗留应用程序，所以请不要建议删除共享库或添加 deployment.xml

嗯，这是工作脚本addSharedLibrary.py <application-name> shared-lib [shared-lib...]

def addSharedLibrary(holder):
    classldr = AdminConfig.showAttribute(holder, 'classloader')
    for x in range(1, len(sys.argv)):
        AdminConfig.create('LibraryRef', classldr, [['libraryName', sys.argv[x]], ['sharedClassloader', 'true']])


def handleWebModules(applicationName):
    webModules = AdminConfig.list('WebModuleDeployment').split('\n')
    for webModule in webModules:
        if (webModule.find(applicationName) != -1):
            print 'Setting for ' + webModule
            addSharedLibrary(webModule)


dep = AdminConfig.getid('/Deployment:' + sys.argv[0] + '/')
addSharedLibrary(AdminConfig.showAttribute(dep, 'deployedObject'))
handleWebModules(app)

AdminConfig.save()

我认为实现此目的的一个好方法是在服务器级别创建一个共享库，然后也在服务器级别创建一个类加载器以加载库。

set serv [$AdminConfig getid /Cell:mycell/Node:mynode/Server:server1/]

print AdminConfig.create('Library', serv, [['name', 'mySharedLibrary'],     ['classPath',  
'home/myProfile/mySharedLibraryClasspath']])

AdminConfig.create('Library', serv,     [['name', 'mySharedLibrary'],              
['classPath','test1.jar;test2.jar;test3.jar']]) 

appServer = AdminConfig.list('ApplicationServer', serv)
print appServer

classLoad = AdminConfig.showAttribute(appServer, 'classloaders')
cleanClassLoaders = classLoad[1:len(classLoad)-1]
classLoader1 = cleanClassLoaders.split(' ')[0]

classLoader1 = AdminConfig.create('Classloader', appServer,     [['mode',  'PARENT_FIRST']])

print AdminConfig.create('LibraryRef', classLoader1,     [['libraryName', 'MyshareLibrary']])

AdminConfig.save()

AdminNodeManagement.syncActiveNodes()

感谢 poussma 提供的 jython 脚本，它适用于以前版本的 WAS... 所以我调整了你的代码，让它在 WAS8 上也能工作：

运行命令行：addSharedLibrary.py <application-name> [shared-lib...]

def addSharedLibrary(holder):
    classldr = AdminConfig.showAttribute(holder, 'classloader')
    for x in range(1, len(sys.argv)):
        AdminConfig.create('LibraryRef', classldr, [['libraryName', sys.argv[x]], ['sharedClassloader', 'true']])


def handleWebModules(applicationName):
    webModules = AdminConfig.list('WebModuleDeployment').split('\r')
    webModules = map(lambda s: s.strip(), webModules)
    for webModule in webModules:
        if (webModule.find(applicationName+'.ear') != -1):
            print 'Setting for ' + webModule
            addSharedLibrary(webModule)


dep = AdminConfig.getid('/Deployment:' + sys.argv[0] + '/')
addSharedLibrary(AdminConfig.showAttribute(dep, 'deployedObject'))
handleWebModules(sys.argv[0])

AdminConfig.save()
