jndi

Currently I am use following code to lookup EJB3 sateless session beans for normal POJO class. (We are in JEE5 so we can not inject Stateless Session Beans in normal POJO class I have to use look up) import javax.naming.Context; import javax.naming.InitialContext; import javax.naming.NamingException; import org.apache.log4j.Logger; public Object getEJB(String jndiName) { logger.debug("WEBSPHERE EJB Lookup : " + jndiName); String modifiedJndiName = ""; Hashtable<Object, Object> properties = new Hashtable<Object, Object>(); properties.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere

I am using tomcat connection pool, jpa, hibernate. The datasource i created in context.xml of tomcat works fine if I try to get it using : source = (DataSource) ((Context) c.lookup("java:comp/env")).lookup("jdbc/kids"); but if i specify this jndi datasource in persistence.xml <persistence-unit name="kids-tomcat" transaction-type="JTA"> <jta-data-source>jdbc/kids</jta-data-source> </persistence-unit> I am getting following exception: org.hibernate.service.jndi.JndiException: Unable to lookup JNDI name [jdbc/kids] Any idea why it could happen ! Finally it worked today after i specified the

I am basically walking the LDAP tree in Active Directory. At each level I query for "(objectClass=*)" . When I do this on the root eg "dc=example,dc=com" I get the exception below. This works fine on our other LDAP instances. For some reason only on our Active Directory server I get this exception. I also get the same exception when using JXplorer on our Active Directory server. From reading around online I found people saying you should turn on following, not sure what that means... So on my controls object ( javax.naming.directory.SearchControls ) that I pass with the query I call

We are getting java.sql.SQLException: Connection has already been closed. exception intermittently while performing a transaction. We are using tomcat 7.X and below is the configuration. <Context docBase="ROOT" reloadable="true" antiJARLocking="true"> <Resource name="jdbc/DS" auth="Container" type="javax.sql.DataSource" driverClassName="org.postgresql.Driver" url="jdbc:postgresql://XXXXXXX" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" username="XXXXXX" password="XXXXXX" maxActive="20" maxIdle="3" minIdle="3" maxWait="10000" removeAbandoned="true"/> </Context> Probably we are missing

I'm using Hibernate 4.0 with a JPA persistence.xml file on Tomcat 7. No Struts, just straight Hibernate with some Jersey services. Here is the exception I'm running into: Caused by: org.hibernate.service.jndi.JndiException: Unable to lookup JNDI name [jdbc/MyDB] at org.hibernate.service.jndi.internal.JndiServiceImpl.locate(JndiServiceImpl.java:68) at org.hibernate.service.jdbc.connections.internal.DatasourceConnectionProviderImpl.configure(DatasourceConnectionProviderImpl.java:116) at org.hibernate.service.internal.StandardServiceRegistryImpl.configureService(StandardServiceRegistryImpl.java

I have a Java application that runs on Weblogic. The application needs to access a stored procedure in a DB2 data base, therefore a JDBC data source is configured and accessed by its JNDI name. Data source: ClassDriver: com.ibm.db2.jcc.DB2Driver Properties: user=MYUSER DatabaseName=MYDB The following example works as expected. Context env = null; DataSource pool = null; Hashtable ht = new Hashtable(); ht.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory"); ht.put(Context.PROVIDER_URL,"t3://myserver:7777"); env = new InitialContext(ht); pool = (DataSource) env.lookup(
