I am using the javax.mail .jar file to read the mail message. But when IM is running then I'm getting the following exception.
I added mail.jar to classpath. Exception in the thread "main" java.lang.NoClassDefFoundError: Javax / mail / messagingE due to outgoing: java.lang.ClassNotFoundException: javax.mail.MessagingException at java.net.URLClassLoader $ 1 .run (unknown source) at java.security.AccessController Privileged on Java.net (basic method).

You are not getting any messaging exposure , VM is complaining that it find messaging one Suppressions can not (although this is probably searching because it wants to throw it, but these are the problems for later.) Check if your mail is actually Includes this class, and check whether your mail.jar is really on the classpath or not.
The last thing may be that the class is incompatible with your version of Java. Compiled classes for 1.5 will not run at 1.4, for example.

I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...
If I have any results from the Active Records, then I have an array of hashes, if I have a reliable load, then every Each organization hash in record hash has a nested hash of its associated records My question is, is there a quick rail system that allows you to merge these nested hashes into a hash per record? An analogy will be changing the records table rows Another resemblance will be converted into a hash at one level of nested hashes. approach 1: select them in the section Include class user has_one: profile end is for square profile: user # street 1, street 2, city etc. end profile = profile.junks (user :). Selection ("User. *, Profile. *") All profiles. First.login Approach 2: Use delegation for class profiles : User # Street 1, Road 2, City etc. Representative: Name ,: name =,: email,: email = ,: from = to & gt; : End of user
