java - Hibernate Initial SessionFactory creation failed -

-

I'm trying to use hibernate to fill in my jsf selectonmenu The problem is that I got an unsuccessful problem creating the initial sessionfire before applying my work in the application center, before installing it in session, and I did not get any errors.

For the complete error now 

  initial session. Java.lang.ClassCastException: org.hibernate.type.StringType can not be inserted in org.hibernate.type.VersionType 
 
   
 
 
 You are very likely to have a  VARCHAR  column  version  column, and hibernate it reverse engineering equipment generates it: 
 
  & lt; Version name = "version" type = "string" & gt; & Lt; Column name = "VERSION" length = "20" /> & Lt; / Edition & gt; Instead of  
 
: 
 
  & lt; Property name = "version" type = "string" & gt; & Lt; Column name = "VERSION" length = "20" /> & Lt; / Property & gt; First of all, I think this is not what you want. Second, the string is not allowed for the version field described in Chapter:  
 
 The version numbers include Hibernate type  long ,  integer ,  Small ,  timestamp  or  calendar . 
 
 
 This problem has been reported in some way (in fact, it should be hibernate, hibernate, and should not be hired) and I look at two ways to solve it.  
  •  Manually fix mapping 
    •  
  •  Give more columns to the column

    windows - Heroku throws SQLITE3 Read only exception -

    -
    After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's...

    lex - Building a lexical Analyzer in Java -

    -
    I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa...

    python - rename keys in a dictionary -

    -
    I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k])
