• Process-to-port mapping with SNMP and/or wmi/wmic in java

  - by Niddy888

  I'm trying to use SNMP to map outgoing ports on my host computer with the application running on the computer that is responsible for that communication. When running "netstat -ano" I get access to Protocol, Local Address (with port), Foreign Address (with port), State and PID. But I want to do this entirely without having to execute "cmd" from Java. By using SNMP OID: .1.3.6.1.2.1.25.4 (.iso.org.dod.internet.mgmt.mib-2.host.hrSWRun) I get access to PID (ex. 1704), Name (ex. cmd.exe), Path (ex. C:\Windows\system32) among others. There is an SNMP OID: .1.3.6.1.2.1.6.13 (.iso.org.dod.internet.mgmt.mib-2.tcp.tcpConnTable) that give you access to TCP connection state, local address, local port, remote address, remote port. But NO PID. So to sum up. My question again: Is there a way to "map" these tables together? Either directly in SNMP with other OID's or in conjunction with WMI / WMIC?

• NHibernate many-to-many mapping

  - by Scozzard

  Hi, I am having an issue with many-to-many mapping using NHibernate. Basically I have 2 classes in my object model (Scenario and Skill) mapping to three tables in my database (Scenario, Skill and ScenarioSkill). The ScenarioSkills table just holds the IDs of the SKill and Scenario table (SkillID, ScenarioID). In the object model a Scenario has a couple of general properties and a list of associated skills (IList) that is obtained from the ScenarioSkills table. There is no associated IList of Scenarios for the Skill object. The mapping from Scenario and Skill to ScenarioSkill is a many-to-many relationship: Scenario * --- * ScenarioSkill * --- * Skill I have mapped out the lists as bags as I believe this is the best option to use from what I have read. The mappings are as follows: Within the Scenario class <bag name="Skills" table="ScenarioSkills"> <key column="ScenarioID" foreign-key="FK_ScenarioSkill_ScenarioID"/> <many-to-many class="Domain.Skill, Domain" column="SkillID" /> </bag> And within the Skill class <bag name="Scenarios" table="ScenarioSkills" inverse="true" access="noop" cascade="all"> <key column="SkillID" foreign-key="FK_ScenarioSkill_SkillID" /> <many-to-many class="Domain.Scenario, Domain" column="ScenarioID" /> </bag> Everything works fine, except when I try to delete a skill, it cannot do so as there is a reference constraint on the SkillID column of the ScenarioSkill table. Can anyone help me? I am using NHibernate 2 on an C# asp.net 3.5 web application solution.

• SQLAlchemy Mapping problem

  - by asdvalkn

  Dear Everyone, I am trying to sqlalchemy to correctly map my data. Note that a unified group is basically a group of groups. (One unifiedGroup maps to many groups but each group can only map to one ug). So basically this is the definition of my unifiedGroups: CREATE TABLE `unifiedGroups` ( `ugID` INT AUTO_INCREMENT, `gID` INT NOT NULL, PRIMARY KEY(`ugID`, `gID`), KEY( `gID`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 ; Note that each row is a ugID, gID tuple. ( I do not know before hand how many gID is per ugID so this is probably the most sensible and simplest method). Definition for my UnifiedGroup class class UnifiedGroup(object): """UnifiedProduct behaves very much like a group """ def __init__(self, ugID): self.ugID=ugID #Added by mapping self.groups=False def __str__(self): return '<%s:%s>' % (self.ugID, ','.join( [g for g in self.groups])) These are my mapping tables: tb_groupsInfo = Table( 'groupsInfo', metadata, Column('gID', Integer, primary_key=True), Column('gName', String(128)), ) tb_unifiedGroups = Table( 'unifiedGroups', metadata, Column('ugID', Integer, primary_key=True), Column('gID', Integer, ForeignKey('groupsInfo.gID')), ) My mapper maps in the following manner: mapper( UnifiedGroup, tb_unifiedGroups, properties={ 'groups': relation( Group, backref='unifiedGroup') }) However, when I tried to do groupInstance.unifiedGroup, I am getting an empty list [], while groupInstance.unifiedGroup.groups returns me an error: AttributeError: 'InstrumentedList' object has no attribute 'groups' Traceback (most recent call last): File "Mapping.py", line 119, in <module> print p.group.unifiedGroup.groups AttributeError: 'InstrumentedList' object has no attribute 'groups' What is wrong?

• Mapping Drive Error - System Error 1808

  - by Julian Easterling

  A vendor is attempting to map and preserve a network drive using nt authority/system; so it stays persistent when the interactive session of the server is lost.

• Issues with ProxyPass and ProxyPassReverse when proxying to localhost and a different TCP port

  - by mbrownnyc

  I am attempting to use ProxyPass and ProxyPassReverse to proxy requests through Apache to another server instance that is bound to the localhost on a different TCP port that the Vhost exists (VHost is bound to :80, when the target is bound to :5000). However, I am repeatedly receiving HTTP 503 when accessing the Location. According to the ProxyPass documentation... <VirtualHost *:80> ServerName apacheserver.domain.local DocumentRoot /var/www/redmine/public ErrorLog logs/redmine_error <Directory /var/www/redmine/public> Allow from all Options -MultiViews Order allow,deny AllowOverride all </Directory> </VirtualHost> PassengerTempDir /tmp/passenger <Location /rhodecode> ProxyPass http://127.0.0.1:5000/rhodecode ProxyPassReverse http://127.0.0.1:5000/rhodecode SetEnvIf X-Url-Scheme https HTTPS=1 </Location> I have tested binding the alternate server to the interface IP address, and the same issue occurs. The server servicing request is an instance of python paste:httpserver, and it has been configured to use the /rhodecode suffix (as I saw this to be mentioned in other posts about ProxyPass). The documentation from the project itself, Rhodecode, reports to use the above. The issue is persistent if I target another server that is serving on a different port. Does ProxyPass allow proxying to a different TCP port? [update] I won't delete this, in case someone comes across the same issue. I had set an ErrorLog, and in that ErrorLog the following error was reported: [Wed Nov 09 11:36:35 2011] [error] (13)Permission denied: proxy: HTTP: attempt to connect to 127.0.0.1:5000 (192.168.100.100) failed [Wed Nov 09 11:36:35 2011] [error] ap_proxy_connect_backend disabling worker for (192.168.100.100) After some more research, I attempted to set SELinux to permissive (echo 0 >/selinux/enforce), and try again. It turns out the SELinux boolean httpd_can_network_connect must be set to 1. For persistence on reboot: setsebool -P httpd_can_network_connect=1

• Synergy Key Mapping

  - by Tauren

  I'm running a Synergy server on Ubuntu and a Synergy+ client on OSX. The server has a standard windows keyboard with shift, ctrl, windows, and alt keys. My MacBookPro has shift, fn, control, alt/option, and command keys. When I press ctrl-c, ctrl-v, etc, the appropriate copy/paste action doesn't happen on the Mac, but it does in Ubuntu. If I'm controlling the mac, and press alt-c, alt-v, then I get the copy/paste action. So I played around with key mapping in synergy.conf and found that the following allows me to do copy/paste with ctrl-c/ctrl-v: section: screens godzilla: mbp.local: ctrl = alt alt = ctrl end Is this all that I need to do? Or are there other mappings that will help as well? The synergy configuration page refers to the following key mappings. What are the equivalent keys for each of these on the Windows keyboard and Mac keyboard? What is a meta or super key? shift = {shift|ctrl|alt|meta|super|none} ctrl = {shift|ctrl|alt|meta|super|none} alt = {shift|ctrl|alt|meta|super|none} meta = {shift|ctrl|alt|meta|super|none} super = {shift|ctrl|alt|meta|super|none} Thanks!

• How to work around blocked outbound hkp port for apt keys

  - by kief_morris

  I'm using Ubuntu 9.10, and need to add some apt repositories. Unfortunately, I get messages like this when running sudo apt-get update: W: GPG error: http://ppa.launchpad.net karmic Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 5A9BF3BB4E5E17B5 W: GPG error: http://ppa.launchpad.net karmic Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 1DABDBB4CEC06767 So, I need to install the keys for these repositories. Under 9.10 we now have the option to do this: sudo add-apt-repository ppa:nvidia-vdpau/ppa See this Ubuntu help article for details. This is great, except that I'm running this on a workstation behind a firewall which blocks outbound connections to pretty much all ports except those required by secretaries running Windows and IE. The port in question here is the hkp service, port 11371. There appear to be ways to manually download keys and install them on apt's keyring. There may even be a way to use add-apt-repository or wget or something to download a key from an alternative server making it available on port 80. However, I haven't yet found a concise set of steps for doing so. What I'm looking for is: How to find a public key for an apt-package (recommendations for resources which have these, and/or tips for searching. Searching for the key hash doesn't seem all that effective so far.) How to retrieve a key (can it be done automatically using gpg or add-apt-repository?) How to add a key to apt's keyring Thanks in advance.

• lsof not showing what port a proc is listening on

  - by ericslaw

  I have many processes on a box listening on several ports. I am trying to map ports to pids. The problem is that lsof is not telling me what ports belong to which process. Given an apache listening on port 80, I can see it listening via netstat: user@host% netstat -an|grep LISTEN|grep 80 *.80 *.* 0 0 49152 0 LISTEN But when I try to map port 80 to a pid I get nothing: user@host% lsof -iTCP:80 -t When I try seeing what sockets that specific pid is using I get: user@host% lsof -lnP -p31 -a -i COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME libhttpd. 31 0 15u IPv4 0x6002d970b80 0t0 TCP *:65535 (LISTEN) Notice the *:65535 in the NAME column. Does anyone know why lsof is not reporting the port in use? I am running as root. I am using a mix of lsof and os versions: lsof v4.77 on Solaris10 sparc lsof v4.72 on Redhat4.2 etc I know that linux solutions can use "netstat -p", so I guess I'm only looking for why solaris isn't working, but I find lsof is frequently silent and not showing me expected data.

• How to setup port forwarding from my Webserver (apache) to my Database server (mysql)

  - by karman888

  Hello again guys, and thank you for your help so far. Here is my problem: I have two remote dedicated servers, one webserver that runs apache, and one db server that runs mysql. The apache server is visible on the internet of course, but the second server is only visible to the apache server because they are connected with LAN. I need to connect to the remote mysql server through internet from my home-pc , but only apache server is visible to my home-pc. How can i setup port-forwarding from my apache server to the mysql server so i will be able to "see" the mysql server from my home-pc? This question is a follow-up from my first question Connect to remote mysql server from my application. Problem is that Mysql server is on LAN in which you answered me and helped me a lot by telling me to do "port-forwarding". I looked over the internet, and i cant find a good how-to to do port-forwarding. I'm an experienced programmer, but have little experience on hardware and networks. I can understand though what must be done, so i just need a litle help to sort things out :) I hope you can help me guys, Thank you in advance p.s. machine that Apache is running is on CentOS, mysql server also CentOS. p.s2 webserver runs WebHostManager i dont know if that makes any difference or it can be made easily through this, i just mention it :)

• Connecting to network device behind NAT from local LAN using the external port and IP

  - by lumbric

  I noticed at several different LANs connected to the Internet through a NAT the following phenomena. There is a server in the LAN and there is a port forwarding to reach this server also from outside the LAN through the NAT. E.g. consider a LAN with the address 192.168.0.* and a SSH server at 192.168.0.2 with port 22 and a forwarding from port 2222 at the NAT 192.168.0.1 to 192.168.0.2:22. If the NAT's external IP is 44.33.22.11, one can connect to the SSH server through 44.33.22.11:2222. Surprisingly this works only from outside the LAN. If one tries to connect to 44.33.22.11:2222 from behind the NAT, there is no answer. Of course one could simply use 192.168.0.2:22, but often it is simpler to use the external IP. The typical use case for me is the configuration on a laptop computer. Usually the user uses any arbitrary Internet connection to connect to his home or office server, but sometimes he will use also the LAN to connect to it and it would be annoying to have to different configurations or bookmarks. Why does it fail to connect from inside the LAN? Is there any good work around?

• Port 80 not accessible Amazon ec2

  - by Jasper

  I have started a Amazon EC2 instance (Linux Redhat)... And Apache as well. But when i try: http://MyPublicHostName I get no response. I have ensured that my Security Group allows access to port 80. I can reach port 22 for sure, as i am logged into the instance via ssh. Within the Amazon EC2 Linux Instance when i do: $ wget http://localhost i do get a response. This confirms Apache and port 80 is indeed running fine. Since Amazon starts instances in VPC, do i have to do anything there... Infact i cannot even ping the instance, although i can ssh to it! Any advice? EDIT: Note that i had edited /etc/hosts file earlier to make 389-ds (ldap) installation work. My /etc/hosts file looks like this(IP addresses as shown as w.x.y.z ) 127.0.0.1   localhost.localdomain localhost w.x.y.z   ip-w-x-y-z.us-west-1.compute.internal w.x.y.z   ip-w-x-y-z.localdomain

• Named query not known error trying to call a stored proc using Fluent NHibernate

  - by Hamman359

  I'm working on setting up NHibernate for a project and I have a few queries that, due to their complexity, we will be leaving as stored procedures. I'd like to be able to use NHibernate to call the sprocs, but have run into an error I can't figure out. Since I'm using Fluent NHibernate I'm using mixed mode mapping as recommended here. However, when I run the app I get a "Named query not known: AccountsGetSingle" exception and I can't figure out why. I think I might have a problem with my HBM mapping since I'm not very familiar with using them but I'm not sure. My NHibernate configuration code is: private ISessionFactory CreateSessionFactory() { return Fluently.Configure() .Database(MsSqlConfiguration.MsSql2005 .ConnectionString((conn => conn.FromConnectionStringWithKey("CIDB"))) .ShowSql()) .Mappings(m => { m.HbmMappings.AddFromAssemblyOf<Account>(); m.FluentMappings.AddFromAssemblyOf<Account>(); }) .BuildSessionFactory(); } My hbm.xml file is: <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> <sql-query name="AccountsGetSingle"> <return alias="Account" class="Core, Account"></return> exec AccountsGetSingle </sql-query> </hibernate-mapping> And the code where I am calling the sproc looks like this: public Account Get() { return _conversation.Session .GetNamedQuery("AccountsGetSingle") .UniqueResult<Account>(); } Any thoughts or ideas would be appreciated. Thanks.

• NHibernate SubclassMap gives DuplicateMappingException

  - by stiank81

  I'm using NHibernate to handle my database - with Fluent configuration. I'm not using Automappings. All mappings are written explicitly, and everything is working just fine. Now I wanted to add my first mapping to a subclass, using the SubclassMap, and I run into problems. With the simplest possible setup an Nhibernate DuplicateMappingException is thrown, saying that the subclass is mapped more than once: NHibernate.MappingException : Could not compile the mapping document: (XmlDocument) ---- NHibernate.DuplicateMappingException : Duplicate class/entity mapping MyNamespace.SubPerson I get this with my simple classes written for testing: public class Person { public int Id { get; set; } public string Name { get; set; } } public class SubPerson : Person { public string Foo { get; set; } } With the following mappings: public class PersonMapping : ClassMap<Person> { public PersonMapping() { Not.LazyLoad(); Id(c => c.Id); Map(c => c.Name); } } public class SubPersonMapping : SubclassMap<SubPerson> { public SubPersonMapping() { Not.LazyLoad(); Map(m => m.Foo); } } Any idea why this is happening? If there were automappings involved I guess it might have been caused by the automappings adding a mapping too, but there should be no automapping. I create my database specifying a fluent mapping: private static ISession CreateSession() { var cfg = Fluently.Configure(). Database(SQLiteConfiguration.Standard.ShowSql().UsingFile("unit_test.db")). Mappings(m => m.FluentMappings.AddFromAssemblyOf<SomeClassInTheAssemblyContainingAllMappings>()); var sessionSource = new SessionSource(cfg.BuildConfiguration().Properties, new TestModel()); var session = sessionSource.CreateSession(); _sessionSource.BuildSchema(session); return session; } Again; note that this only happens with SubclassMap. ClassMap's are working just fine!

• Fluent nhibernate: Enum in composite key gets mapped to int when I need string

  - by Quintin Par

  By default the behaviour of FNH is to map enums to its string in the db. But while mapping an enum as part of a composite key, the property gets mapped as int. e.g. in this case public class Address : Entity { public Address() { } public virtual AddressType Type { get; set; } public virtual User User { get; set; } Where AddresType is of public enum AddressType { PRESENT, COMPANY, PERMANENT } The FNH mapping is as mapping.CompositeId().KeyReference(x => x.User, "user_id").KeyProperty(x => x.Type); the schema creation of this mapping results in create table address ( Type INTEGER not null, user_id VARCHAR(25) not null, and the hbm as <composite-id mapped="true" unsaved-value="undefined"> <key-property name="Type" type="Company.Core.AddressType, Company.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"> <column name="Type" /> </key-property> <key-many-to-one name="User" class="Company.Core.CompanyUser, Company.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"> <column name="user_id" /> </key-many-to-one> </composite-id> Where the AddressType should have be generated as type="FluentNHibernate.Mapping.GenericEnumMapper`1[[Company.Core.AddressType, How do I instruct FNH to mappit as the default string enum generic mapper?

• C# SerialPort - Problems mixing ports with different baud rates.

  - by GrandAdmiral

  Greetings, I have two devices that I would like to connect over a serial interface, but they have incompatible connections. To get around this problem, I connected them both to my PC and I'm working on a C# program that will route traffic on COM port X to COM port Y and vice versa. The program connects to two COM ports. In the data received event handler, I read in incoming data and write it to the other COM port. To do this, I have the following code: private void HandleDataReceived(SerialPort inPort, SerialPort outPort) { byte[] data = new byte[1]; while (inPort.BytesToRead > 0) { // Read the data data[0] = (byte)inPort.ReadByte(); // Write the data if (outPort.IsOpen) { outPort.Write(data, 0, 1); } } } That code worked fine as long as the outgoing COM port operated at a higher baud rate than the incoming COM port. If the incoming COM port was faster than the outgoing COM port, I started missing data. I had to correct the code like this: private void HandleDataReceived(SerialPort inPort, SerialPort outPort) { byte[] data = new byte[1]; while (inPort.BytesToRead > 0) { // Read the data data[0] = (byte)inPort.ReadByte(); // Write the data if (outPort.IsOpen) { outPort.Write(data, 0, 1); while (outPort.BytesToWrite > 0); //<-- Change to fix problem } } } I don't understand why I need that fix. I'm new to C# (this is my first program), so I'm wondering if there is something I am missing. The SerialPort defaults to a 2048 byte write buffer and my commands are less than ten bytes. The write buffer should have the ability to buffer the data until it can be written to a slower COM port. In summary, I'm receiving data on COM X and writing the data to COM Y. COM X is connected at a faster baud rate than COM Y. Why doesn't the buffering in the write buffer handle this difference? Why does it seem that I need to wait for the write buffer to drain to avoid losing data? Thanks!

• With NHibernate, how can I add a child object when updating a parent object?

  - by BMZ

  I have a simple Parent/Child relationship between a Person object and an Address object. The Person object exists in the DB. After doing a Get on the Person, I add a new Address object to the Address sub-object list of the parent, and do some other updates to the Person object. Finally, I do an Update on the Person object. With a SQL trace window, I can see the update to the Person object to the Person table and the Insert of the Address record to the Address table. The issue is that, after the update is performed, the AddressId (primary key on the Address object) is still set to 0, which is what it defaults to when you first initialize the Address object. I have verified that when I do an Add, this value is set correctly. Is this a known issue when trying to add sub-objects as part of an NHibernate UPDATE? Sample code and mapping files are below Thanks <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> <class name="BusinessEntities.Wellness.Person,BusinessEntities.Wellness" table="Person" lazy="true" dynamic-insert="true" dynamic-update="false"> <id name="Personid" column="PersonID" type="int"> <generator class="native" /> </id> <version type="binary" generated="always" name="RecordVersion" column="`RecordVersion`"/> <property type="int" not-null="true" name="Customerid" column="`CustomerID`" /> <property type="AnsiString" not-null="true" length="9" name="Ssn" column="`SSN`" /> <property type="AnsiString" not-null="true" length="30" name="FirstName" column="`FirstName`" /> <property type="AnsiString" not-null="true" length="35" name="LastName" column="`LastName`" /> <property type="AnsiString" length="1" name="MiddleInitial" column="`MiddleInitial`" /> <property type="DateTime" name="DateOfBirth" column="`DateOfBirth`" /> <bag name="PersonAddresses" inverse="true" lazy="true" cascade="all"> <key column="PersonID" /> <one-to-many class="BusinessEntities.Wellness.PersonAddress,BusinessEntities.Wellness" / </bag> </class> </hibernate-mapping> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> <class name="BusinessEntities.Wellness.PersonAddress,BusinessEntities.Wellness" table="PersonAddress" lazy="true" dynamic-insert="true" dynamic-update="false"> <id name="PersonAddressId" column="PersonAddressID" type="int"> <generator class="native" /> </id> <version type="binary" generated="always" name="RecordVersion" column="`RecordVersion`" /> <property type="AnsiString" not-null="true" length="1" name="AddressTypeid" column="`AddressTypeID`" /> <property type="AnsiString" not-null="true" length="60" name="AddressLine1" column="`AddressLine1`" /> <property type="AnsiString" length="60" name="AddressLine2" column="`AddressLine2`" /> <property type="AnsiString" length="60" name="City" column="`City`" /> <property type="AnsiString" length="2" name="UsStateId" column="`USStateID`" /> <property type="AnsiString" length="5" name="UsPostalCodeId" column="`USPostalCodeID`" /> <many-to-one name="Person" cascade="none" column="PersonID" /> </class> </hibernate-mapping> Person newPerson = new Person(); newPerson.PersonName = "John Doe"; newPerson.SSN = "111111111"; newPerson.CreatedBy = "RJC"; newPerson.CreatedDate = DateTime.Today; personDao.AddPerson(newPerson); Person updatePerson = personDao.GetPerson(newPerson.PersonId); updatePerson.PersonAddresses = new List<PersonAddress>(); PersonAddress addr = new PersonAddress(); addr.AddressLine1 = "1 Main St"; addr.City = "Boston"; addr.State = "MA"; addr.Zip = "12345"; updatePerson.PersonAddresses.Add(addr); personDao.UpdatePerson(updatePerson); int addressID = updatePerson.PersonAddresses[0].AddressId;

• using onDelete with Doctrine 2

  - by tamir

  I can't get the onDelete to work in Doctrine2 (with YAML Mapping). I tried this relation in my Product class: oneToOne: category: targetEntity: Category onDelete: CASCADE But that doesn't work.. EDIT: I've set the ON DELETE: CASCADE manually in the database imported the YAML mapping with doctrine:mapping:import, emptied the database updated it from the schema with doctrine:schema:update and got no ON DELETE in the foreign key.. so looks like even Doctrine doesn't know how to do it lol..

• Is this pdo bug fixed now?

  - by user198729

  Note that you can specify a port number with "port=####", but this port number will be ignored if the host is localhost. If you want to connect to a local port other than the default, use host=127.0.0.1 instead of localhost. Quoted from this page,has anyone verified if it has been fixed?

• NHibernate: Dynamically swapping a single domain model between multiple physical data models

  - by Nigel

  Hi In this article Ayende describes how to map a single domain model to multiple physical data models. Is it possible to extend this principle such that the mapping can chosen dynamically? So for example, imagine we had an entity that could be written to the same physical schema in three ways depending on its current status, and lets assume that regardless of status each entity had a unique identifier. One solution would be to represent the entity in its different states with three separate classes: one for each mapping. Then the entity could be loaded and in order to change its state the entity could be mapped to a class representing one of its other states and then saved back to the schema, making use of a different mapping. I was wondering if it is at all possible to have the same entity represented by one class that held a status flag (kind of like a discriminator), and any save to the schema would choose the appropriate mapping based on the value of the status flag. Hopefully that made sense! Many thanks.

• How to find unmapped properties in a NHibernate mapped class?

  - by haarrrgh

  I just had a NHibernate related problem where I forgot to map one property of a class. A very simplified example: public class MyClass { public virtual int ID { get; set; } public virtual string SomeText { get; set; } public virtual int SomeNumber { get; set; } } ...and the mapping file: <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="MyAssembly" namespace="MyAssembly.MyNamespace"> <class name="MyClass" table="SomeTable"> <property name="ID" /> <property name="SomeText" /> </class> </hibernate-mapping> In this simple example, you can see the problem at once: there is a property named "SomeNumber" in the class, but not in the mapping file. So NHibernate will not map it and it will always be zero. The real class had a lot more properties, so the problem was not as easy to see and it took me quite some time to figure out why SomeNumber always returned zero even though I was 100% sure that the value in the database was != zero. So, here is my question: Is there some simple way to find this out via NHibernate? Like a compiler warning when a class is mapped, but some of its properties are not. Or some query that I can run that shows me unmapped properties in mapped classes...you get the idea. (Plus, it would be nice if I could exclude some legacy columns that I really don't want mapped.)
