通过jython安装Ear文件，从而在Websphere Application Server启动中产生问题

Question

hi i have a below logic to install both war and ear files being in warpath into websphere. after running the script it installs both war and ears successfully but during server stratup its throwing error only for ear file. if i use same commandlogic to execute directly on wsadmin for ear file installation it works fine and even server comes up without error,can any one analyse whats going wrong in the script

my logic:

for fname in os.listdir(warPath):
        if fname.endswith(".ear") or fname.endswith(".war"):
            file_list.append(fname)


    for i in range(len(file_list)):
        earFile=file_list[i]
        letter=earFile[0]

        if (letter == "a"):
            applicationName="admin-guiwar"
            installApp(cellName, nodeName, serverName, earFile, applicationName);
            classldr(applicationName)
        if (letter == "i"):
            applicationName="internetbank-guiwar"
            installApp(cellName, nodeName, serverName, earFile, applicationName);
            classldr(applicationName)
        if (letter == "m"):
            applicationName="mobilegateway"
            installApp(cellName, nodeName, serverName, earFile, applicationName);
            classldr(applicationName)
        if (letter == "n"):
            applicationName="netbanksrv-ear"
            installApp(cellName, nodeName, serverName, earFile, applicationName);
            classldr(applicationName)

def installApp (cellName, nodeName, serverName, warFileName, applicationName):
    fullPath = warPath+"/"+warFileName
    node = "-node "+nodeName
    cell = "-cell "+cellName
    svr = "-server "+serverName
    appName = "-appname "+applicationName
    AdminApp.install(fullPath, [node, cell, svr, appName])

Your deploy script is OK. But you have a different issue with Spring:

 Could not instantiate bean class [pegasus.integration.framework.HttpClientUrlResource]: Constructor threw exception; nested exception is java.net.MalformedURLException: no protocol: null

I think you have to set class loader policy to PARENT_LAST for your application.
