Error:

weblogic.jms.common.MessageFormatException: JMSClientExceptions: Invalid property name, "my-personnal-id"

Fix:

Rename the property as myPersonalId for instance. Indeed, owing to JMS specification, properties on JMS messages must be written in alphanumeric characters. Therefore, hyphen '-' and periods '.' are forbidden.

Error:

 java.lang.ClassNotFoundException: net.sf.cglib.transform.impl.InterceptFieldEnabled  at java.net.URLClassLoader$1.run(URLClassLoader.java:200)  at java.security.AccessController.doPrivileged(Native Method)  at java.net.URLClassLoader.findClass(URLClassLoader.java:188)  at java.lang.ClassLoader.loadClass(ClassLoader.java:306) 

Fix: add cgilib-nodep.jar to your classpath.

Error:

Error: LDAPLocalException: com.novell.ldap.ldif_dsml.LDIFReader: modify record not ends with '-' in the record starting on line 38 of the file. (82) Local Error

Fix:

• go to the line hinted in the error (here: 38)
• get the block of the entry which is modified, for instance:

dn: cn=foo,ou=OUfoos,ou=Groups, dc=DCfoos
changetype: modify
add: uniqueMember 
uniqueMember: cn=myFoo, ou=OUfoos, ou=Groups, dc=DCfoos

• then add a character '-' at the end of this block, you get:

dn: cn=foo,ou=OUfoos,ou=Groups, dc=DCfoos
changetype: modify
add: uniqueMember 
uniqueMember: cn=myFoo, ou=OUfoos, ou=Groups, dc=DCfoos

Error:

 LDAPLocalException: com.novell.ldap.ldif_dsml.LDIFReader: Version line must be the first meaningful line(on line 1 of the file) (82) Local Error 

Fix: add this line at the bottom of your Ldif file:

 version: 1 

Error:

nested exception is java.lang.NoClassDefFoundError: net/sf/ezmorph/Morpher org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:899) org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:793) org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:476) org.springframework.web.servlet.FrameworkServlet.doPost(FrameworkServlet.java:441)

Fix: add ezmorph.jar to your classpath.

Error:

 java.lang.ClassNotFoundException: net.sf.cglib.transform.impl.InterceptFieldEnabled  at java.net.URLClassLoader$1.run(URLClassLoader.java:200)  at java.security.AccessController.doPrivileged(Native Method)  at java.net.URLClassLoader.findClass(URLClassLoader.java:188)  at java.lang.ClassLoader.loadClass(ClassLoader.java:306) 

Fix: add ehcache.jar in your classpath.

Dolphin extends the switch operator to String

Read the rest of this entry »

Tiger (Java 5) introduced new syntax, among which generics are the most used. Mustang (Java 6) did not offer anything new. Dolphin (Java 7) will introduce a new scheme, the “diamond syntax”. We deal of diamond because of the look of theses characters: “<>”

To sum up quickly, in Java 5 we have to write:

[java]
List<Integer>  myList = new ArrayList<Integer>()
Map<String, List<Double>> myMap = new Hashmap<String, List<Double>>();[/java]

On last Dolphin development releases, we can simply write:

[java]
Lis<Integer> myList = new ArrayList<>()
Map<String, List<Double>> myMap = new Hashmap<>();[/java]

There’s nothing revolutionary, but developpers will save a little more time ;-).

Abstract: we need copy all Java files in a folder and its subdirectories.

Solution:

 xcopy C:\<source folder>\*.java C:\<destination folder>\

 weblogic.management.ManagementException: Unable to obtain lock on /$HOME/.../myDomain/tmp/myServer.lok. Server may already be running at weblogic.management.internal.ServerLocks.getServerLock(ServerLocks.java:159) at weblogic.management.internal.ServerLocks.getServerLock(ServerLocks.java:58) at weblogic.management.internal.DomainDirectoryService.start(DomainDirectoryService.java:75) at weblogic.t3.srvr.ServerServicesManager.startService(ServerServicesManager.java:374) at weblogic.t3.srvr.ServerServicesManager.startInStandbyState(ServerServicesManager.java:125) at weblogic.t3.srvr.T3Srvr.initializeStandby(T3Srvr.java:630) at weblogic.t3.srvr.T3Srvr.startup(T3Srvr.java:402) at weblogic.t3.srvr.T3Srvr.run(T3Srvr.java:361) at weblogic.Server.main(Server.java:67) 

Fix:

• If possible, ensure you have admin rights
• else:
  • delete /$HOME/.../myDomain/cache
  • delete /$HOME/.../myDomain/data/ldap/ldapfiles/*.lok
  • delete /$HOME/.../myDomain/data/stores/diagnostics/*
  • delete /$HOME/.../myDomain/data/stores/default/*
