  • SpringMvc java.lang.NullPointerException When Posting Form To Server [closed]

    - by dev_darin
    I have a form with a user name field on it when i tab out of the field i use a RESTFUL Web Service that makes a call to a handler method in the controller. The method makes a call to a DAO class that checks the database if the user name exists. This works fine, however when the form is posted to the server i call the same exact function i would call in the handler method however i get a java.lang.NullPointerException when it accesses the class that makes a call to the DAO object. So it does not even access the DAO object the second time. I have exception handlers around the calls in all my classes that makes calls. Any ideas as to whats happening here why i would get the java.lang.NullPointerException the second time the function is called.Does this have anything to do with Spring instantiating DAO classes using a Singleton method or something to that effect? What can be done to resolve this? This is what happens the First Time The Method is called using the Web Service(this is suppose to happen): 13011 [http-8084-2] INFO com.crimetrack.jdbc.JdbcOfficersDAO - Inside jdbcOfficersDAO 13031 [http-8084-2] DEBUG org.springframework.jdbc.core.JdbcTemplate - Executing prepared SQL query 13034 [http-8084-2] DEBUG org.springframework.jdbc.core.JdbcTemplate - Executing prepared SQL statement [SELECT userName FROM crimetrack.tblofficers WHERE userName = ?] 13071 [http-8084-2] DEBUG org.springframework.jdbc.datasource.DataSourceUtils - Fetching JDBC Connection from DataSource 13496 [http-8084-2] DEBUG org.springframework.jdbc.core.StatementCreatorUtils - Setting SQL statement parameter value: column index 1, parameter value [adminz], value class [java.lang.String], SQL type unknown 13534 [http-8084-2] DEBUG org.springframework.jdbc.datasource.DataSourceUtils - Returning JDBC Connection to DataSource 13537 [http-8084-2] INFO com.crimetrack.jdbc.JdbcOfficersDAO - No username was found in exception 13537 [http-8084-2] INFO com.crimetrack.service.ValidateUserNameManager - UserName :adminz does NOT exist The Second time When The Form Is 'Post' and a validation method handles the form and calls the same method the web service would call: 17199 [http-8084-2] INFO com.crimetrack.service.OfficerRegistrationValidation - UserName is not null so going to check if its valid for :adminz 17199 [http-8084-2] INFO com.crimetrack.service.OfficerRegistrationValidation - User Name in try.....catch block is adminz 17199 [http-8084-2] INFO com.crimetrack.service.ValidateUserNameManager - Inside Do UserNameExist about to validate with username : adminz 17199 [http-8084-2] INFO com.crimetrack.service.ValidateUserNameManager - UserName :adminz EXCEPTION OCCURED java.lang.NullPointerException ValidateUserNameManager.java public class ValidateUserNameManager implements ValidateUserNameIFace { private OfficersDAO officerDao;

  • How do I start "Ubuntu classic desktop" (no effects) from the command line

    - by Andrew Stern
    I am able to run sessions over an ssh connection but I rather use the "Ubuntu classic desktop (no effects)" version on Ubuntu 11.04 instead of the new Unity since I don't have 3d support on the laptop I'm using to display the graphical User Interface. How can I startup the older gnome-session without the 3d effects? I tried gnome-session but it seems to be the option with the 3d effects and I want a more stripped down session over my ssh session.

  • Splitting a texture atlas into seperate images

    - by bigtunacan
    I'm doing a port of an existing game and the designer no longer has all of the original art; he only has the resulting texture atlases he used when developing for iPad. The tool I'm using won't support these files so I need to break them back out into separate PNG files. I'm hoping someone knows of a software tool that does this. PC software would be preferred in this case, but Mac would suffice.

  • Launchpad ppa supporting multiple versions of Ubuntu

    - by unknownone
    Is it possible for a launchpad ppa to support multiple Ubuntu versions such as 10.04 and 12.04 when the package itself was built on a 12.04 machine? When trying to add the ppa to a older machine, it gives an error saying it was made on a 12.04 system and that it could not install. I'd like sudo get-apt-install my-app to work with both 10.04 and 12.04, and I am new to packaging and ppa's so I do not know if anything like this exists. Any help would be appreciated, thanks!

  • Multiple country-specific domains or one global domain [closed]

    - by CJM
    Possible Duplicate: How should I structure my urls for both SEO and localization? My company currently has its main (English) site on a .com domain with a .co.uk alias. In addition, we have separate sites for certain other countries - these are also hosted in the UK but are distinct sites with a country-specific domain names (.de, .fr, .se, .es), and the sites have differing amounts of distinct but overlapping content, For example, the .es site is entirely in Spanish and has a page for every section of the UK site but little else. Whereas the .de site has much more content (but still less than the UK site), in German, and geared towards our business focus in that country. The main point is that the content in the additional sites is a subset of the UK, is translated into the local language, and although sometimes is simply only a translated version of UK content, it is usually 'tweaked' for the local market, and in certain areas, contains unique content. The other sites get a fraction of the traffic of the UK site. This is perfectly understandable since the biggest chunk of work comes from the UK, and we've been established here for over 30 years. However, we are wanting to build up our overseas business and part of that is building up our websites to support this. The Question: I posed a suggestion to the business that we might consider consolidating all our websites onto the .com domain but with /en/de/fr/se/etc sections, as plenty of other companies seem to do. The theory was that the non-english sites would benefit from the greater reputation of the parent .com domain, and that all the content would be mutually supporting - my fear is that the child domains on their own are too small to compete on their own compared to competitors who are established in these countries. Speaking to an SEO consultant from my hosting company, he feels that this move would have some benefit (for the reasons mentioned), but they would likely be significantly outweighed by the loss of the benefits of localised domains. Specifically, he said that since the Panda update, and particularly the two sets of changes this year, that we would lose more than we would gain. Having done some Panda research since, I've had my eyes opened on many issues, but curiously I haven't come across much that mentions localised domain names, though I do question whether Google would see it as duplicated content. It's not that I disagree with the consultant, I just want to know more before I make recommendations to my company. What is the prevailing opinion in this case? Would I gain anything from consolidating country-specific content onto one domain? Would Google see this as duplicate content? Would there be an even greater penalty from the loss of country-specific domains? And is there anything else I can do to help support the smaller, country-specific domains?

  • Wrapping REST based Web Service

    - by PaulPerry
    I am designing a system that will be running online under Microsoft Windows Azure. One component is a REST based web service which will really be a wrapper (using proxy pattern) which calls the REST web services of a business partner, which has to do with BLOB storage (note: we are not using azure storage). The majority of the functionality will be taking a request, calling our partner web service, receiving the request and then passing that back to the client. There are a number of reasons for doing this, but one of the big ones is that we are going to support three clients: our desktop application (win and mac), mobile apps (iOS), and a web front end. Having a single API which we then send to our partner protects us if that partner ever changes. I want our service to support both JSON and XML for the data transfer format, JSON for web and probably XML for the desktop and mobile (we already have an XML parser in those products). Our partner also supports both of these formats. I was planning on using ASP.NET MVC 4 with the Web API. As I design this, the thing that concerns me is the static type checking of C#. What if the partner adds or removes elements from the data? We can probably defensively code for that, but I still feel some concern. Also, we have to do a fair amount of tedious coding, to setup our API and then to turn around and call our partner’s API. There probably is not much choice on it though. But, in the back of my mind I wonder if maybe a more dynamic language would be a better choice. I want to reach out and see if anybody has had to do this before, what technology solutions they have used to (I am not attached to this one, these days Azure can host other technologies), and if anybody who has done something like this can point out any issues that came up. Thanks! Researching the issue seems to only find solutions which focus on connecting a SOAP web service over a proxy server, and not what I am referring to here. Note: Cross posted (by suggestion) from http://stackoverflow.com/questions/11906802/wrapping-rest-based-web-service Thank you!
