The meaning of NoInitialContextException error
(13 answers)
Closed 9 years ago.
When i run a JMS related application, i am encountering the following exception error.
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
We are using Sun Application Server 9.1
Any idea what are we missing?
I already tried adding the following but result still the same
Properties env = new Properties();
env.put("java.naming.factory.initial","com.sun.jndi.cosnaming.CNCtxFactory");
Context ctx = new InitialContext(env);
A very common error can be that you have not added the jboss-client.jar!
or alternate jar if using weblogic.
I was facing the same problrm while working with spring & weblogic . I had resolved it by setting two properties
System.getProperties().put("java.naming.factory.initial","weblogic.jndi.WLInitialContextFactory");
System.getProperties().put("java.naming.provider.url", "t3://localhost:80")
In my environment, setting Context.INITIAL_CONTEXT_FACTORY wasn't enough. I also had to set Context.URL_PKG_PREFIXES, explained at http://docs.oracle.com/javase/6/docs/api/javax/naming/Context.html#URL_PKG_PREFIXES.

In my old setup for Quarkus 1.3.2.Final
I have this in my property file
quarkus.vault.url=${vault_path}
quarkus.vault.tls.use-kubernetes-ca-cert=true
quarkus.vault.authentication.kubernetes.role=${someVaultRole}
quarkus.vault.tls.ca-cert=${someTlsCertLocation}
quarkus.vault.kv-secret-engine-mount-path=${someSecretEngingPath}
when i tried to access the secrets using VaultKVSecretEngine.readSecret(path), it gives me the secrets for that path
But when I try to migrate to Quarkus 1.4.2.Final, I got this error
"io.quarkus.vault.runtime.client.VaultClientException code=403 body={\"errors\":[\"1 error occurred:\\n\\t* permission denied\\n\\n\"]}\
when i tried to call VaultKVSecretEngine.readSecret(path) with my old setup.
Question is, what are the configs in my application.properties that i missed for quarkus 1.4.2.final vault access?
since by default, quarkus 1.4.2.Final uses kv-secret-engine-version 2, it is needed to specify the kv-secret-engine-version to version 1 when migrating from quarkus 1.3.2.Final to 1.4.2.Final since 1.3.2.Final uses kv-secret-engine-version 1
I am getting the following error on Line #4 of code below in IBM Websphere
Liberty Profile 16.0.0
InputStream keystoreStream = EncryptionUtility.class.getResourceAsStream(keyStoreLocation);
KeyStore keystore = KeyStore.getInstance("JCEKS");
keystore.load(keystoreStream, storePass.toCharArray());
Key key = keystore.getKey(alias, keyPass.toCharArray());
Which results in the following exception:
Caused by: java.security.UnrecoverableKeyException: com.ibm.crypto.provider.AESSecretKey
at com.sun.crypto.provider.KeyProtector.unseal(KeyProtector.java:358)

at com.comdata.base.helper.EncryptionUtility.initSymmetricKey(EncryptionUtility.java:134)
Any ideas why this is happening? Is anything need to be configured for cryptography?
I poked through the code of keyProtector.java in JDK 7 and UnrecoverableKeyException is triggered by ClassNotFoundException
com.ibm.crypto.provider.AESSecretKey
Do we need to install any feature via installUtility?
Any ideas why this is happening? Is anything need to be configured for cryptography?
The class not being found (com.ibm.crypto.provider.AESSecretKey) is from the IBM JDK.
It looks like your keystore was created using the IBM JDK and thus has a key packaged in it that uses the AESSecretKey from the IBM JDK.
At runtime, your Liberty server is probably using a non-IBM JDK, which would not have this IBM JDK specific class in it.
Do we need to install any feature via installUtility?
Nope. The missing class should be provided by the JDK, as opposed to a Liberty feature.
I'm working on deploying application to WebSphere 7 using python script and the script is throwing exception at this line:-
AdminTask.listTCPEndPoints('abc(abc)')
If I run the above command before I run the python script, it works fine. It gives me an error ADMF0003E: Invalid parameter value. But the same command fails in the python script with this error:
wsadmin>AdminTask.listTCPEndPoints('abc(abc)')
WASX7015E: Exception running command: "AdminTask.listTCPEndPoints('abc(abc)')"; exception information: com.ibm.websphere.management.cmdframework.CommandValidationException: ADMF0007E: target object is required.
I can guess that there something in the python script that is causing this issue, but I don't understand why is the AdminTask.listTCPEndPoints command is not able to see the parameter being passed. I'm new to WebSphere, I have only used it in past but never configured it. Any help/insight would be highly appreciated.
Thanks!
Added stack trace of interactive mode option

Follow this link. It appears that you have not specified the target object that's why that error is coming.
I suggest use the following command as a starter
print AdminTask.listTCPEndPoints('-interactive')
Note: Instead of copying and pasting the command, type it on the command line. sometimes command editor does not take the command after pasting it directly.
Okay, I was able to fix the error. I was getting that error because as part of the application deployment script, I was copying few of my application jars to WebSphere's java/jre/lib/ext directory so that those are available in classpath. In one of those jar, I had bundled an IBM class (Base64Coder.class) which was required by a class in my jar and it was corrupting the WebSphere AdminTask utility. When I removed that Base64Coder.class from my jar, python script worked fine. I believe, the reason it corrupted WebSphere was that there was a duplication of the same class in the JVM as the class comes with IBM WebSphere installation and was present in AppServer/runtimes/com.ibm.ws.webservices.thinclient_7.0.0.jar
I am trying to set java options for my spring application in open shift and its not working. I tried exporting JAVA_OPTIONS and _JAVA_OPTIONS in my app and still I see a file not found exception in my spring initialization exception.
I am trying to load a properties file in spring which is picked based on the environment variable
stack trace:
org.springframework.beans.factory.BeanInitializationException: Could not load properties; nested exception is java.io.FileNotFoundException: Could not open ServletContext resource [/WEB-INF/config_${targetEnv}.properties]
any help is appreciated.
You should be using the JAVA_OPTS_EXT environment variable to set any extra JAVA_OPTS that you would like your application to use.
I am trying to deploy a web application using WSAdmin tool. But it is throwing an error.
JACl script that I am using is :
$AdminApp install /opt/www/temp/SampleApp.war {-nopreCompileJSPs -nodeployejb -server delivery -cell delivery_cell -node delivery_node -appname SampleApp -contextroot SampleApp -MapWebModToVH {{"SampleApp" SampleApp.war,WEB-INF/web.xml default_host}}}
Error I am getting is:
com.ibm.ws.scripting.ScriptingException: WASX7109E: Insufficient data for install task "MapResRefToEJB
ADMA0007E: A validation error occurred in task Mapping resource references to resources. The Java Naming and Directory Interface (JNDI) name is not specified for resource reference jdbc/app_DB in module SampleApp with EJB name.
From the error above I understand that I need to configure my JNDI with -MapResRefToEJB. I tried to understand this option but getting too confused.
Can anyone help me to resolve this issue?
These errors appear to be caused by the MapResRefToEJB option in
the wsadmin command not being set correctly, or the resource it is pointing to
not existing correctly in the web.xml file.
Additional information on MapResRefToEJB
Options for the AdminApp object install, installInteractive, edit,
editInteractive, update, and updateInteractive commands
