Apache Tomcat Realm JDBCRealm with Hibernate

noreply@blogger.com (Yasin Hasan Karanfil) — Thu, 17 Mar 2011 12:31:00 +0000

If you need a restriction to access of your java web project, you can use Apache Tomcat Realm feature. If you need to store users on db, and also access this users as a POJO in jour project, you need to use Hibernate as well, please follow this steps.

In hbm.xml file, define this table
<class name="com.karanfil.shared.Role" table="ROL_ROLES">
<meta attribute="class-description">
JDBC Realm Roles for Tomcat Authentication
</meta>
<id name="RoleName" type="string" length="25" column="ROL_ROLENAME">
</id>
</class>
<class name="com.karanfil.shared.User" table="USR_USERS">
<meta attribute="class-description">
JDBC Realm Users for Tomcat Authentication
</meta>
<id name="UserName" type="string" length="25" column="USR_USERNAME">
</id>
<property name="UserPass" type="string" length="25" column="USR_USERPASSWORD" not-null="true" />
<property name="FirstName" type="string" column="USR_FIRSTNAME" not-null="false" />
<property name="SurName" type="string" column="USR_SURNAME" not-null="false" />
<set name="UserRoles" table="USER_ROLES" cascade="all" lazy="true">
<key column="USR_USERNAME" />
<many-to-many column="ROL_ROLENAME" class="com.karanfil.shared.Role" />

After defining the objects, create POJO objects using Hibernate plug-in.

Now, open ApacheTomcat\conf\server.xml file
Add these lines
<Realm className="org.apache.catalina.realm.JDBCRealm"
driverName="org.gjt.mm.mysql.Driver"
connectionURL="jdbc:mysql://localhost/karanfil"
connectionName="root" connectionPassword="root"
userTable="USR_USERS" userNameCol="USR_USERNAME" userCredCol="USR_USERPASSWORD"
userRoleTable="USER_ROLES" roleNameCol="ROL_ROLENAME" />

Now in your project, WEB-INF\web.xml file
add these lines, and change it to make most suitable for your project.

<security-constraint>
<web-resource-collection>
<web-resource-name>MyFirst</web-resource-name>
<description> accessible by authenticated users of the tomcat role</description>
<url-pattern>*.jsp</url-pattern>
<url-pattern>*.html</url-pattern>
<url-pattern>*.htm</url-pattern>
<url-pattern>/brugwt/greet</url-pattern>
<url-pattern>/upload</url-pattern>
<url-pattern>/Worker</url-pattern>
<http-method>GET</http-method>
<http-method>POST</http-method>
<http-method>PUT</http-method>
<http-method>DELETE</http-method>
</web-resource-collection>
<auth-constraint>
<description>These roles are allowed access</description>
<role-name>superuserrole</role-name>
<role-name>datainputrole</role-name>
<role-name>consultantrole</role-name>
</auth-constraint>
</security-constraint>

<login-config>
<auth-method>FORM</auth-method>
<realm-name>MyFirst Protected Area</realm-name>
<form-login-config>
<form-login-page>/login.html</form-login-page>
<form-error-page>/autherr.html</form-error-page>
</form-login-config>
</login-config>

<security-role>
<description>Only 'tomcat' role is allowed to access this web application</description>
<role-name>tomcat</role-name>
</security-role>

<security-role>
<description>Only 'administrator' role is allowed to access this web application</description>
<role-name>administrator</role-name>
</security-role>

Now the last step is creating users and roles on the db, you can do this using SQL or tools like MySql Query browser, Microsoft SQL Server Management Studio

Path is not a working copy directory Error

noreply@blogger.com (Yasin Hasan Karanfil) — Thu, 17 Mar 2011 12:30:00 +0000

If Subclipse complains about this error

Path is not a working copy directory
svn: '[original (pre-move) directory path]' is not a working copy

Doing things outside of Eclipse is more likely to create problems than solve
them.

To delete the cache, close Eclipse. The cache is stored in:
[workspace]/.metadata/.plugins/org.eclipse.core.resources/.projects/PROJECTNAME/.syncinfo

So you can just find and delete all files named .syncinfo in
[workspace]/.metadata/.plugins/org.eclipse.core.resources/.projects.

Dozer Mapping Framework

noreply@blogger.com (Yasin Hasan Karanfil) — Thu, 17 Mar 2011 12:15:00 +0000

If you have some serialization problems in a GWT project, or if you need to transfer the data inside a POJO to another POJO, you can use dozer framework to do this.

If you are using Hibernate in your project and you have objects and DTO objects, you don't have to write data transfer code between these objects, you can use dozer framework to do these tasks automatically.

DozerBeanMapperSingletonWrapper.getInstance().map(record, RecordDTO.class));

Excel Translate Function

noreply@blogger.com (Yasin Hasan Karanfil) — Thu, 17 Mar 2011 12:06:00 +0000

Using Google Docs, you can translate excel documents to another language using Google Translate service.

To be able to do this use this function

=GoogleTranslate("text", "source language","target language")

instead of "text", you can use the cell number

You can also detect the language of a text
=DetectLanguage("text")

“Could not find resource assembly” error on Windows Mobile

noreply@blogger.com (Yasin Hasan Karanfil) — Fri, 05 Mar 2010 15:10:00 +0000

You should avoid deploying the System_SR cab file; In project properties, select Devices tab uncheck .net framework deployment

If it didn’t work

Copy the System_SR_ENU.CAB file to the emulator and install it. You can check this folders

C:\Program Files (x86)\Microsoft.NET\SDK\CompactFramework\v2.0\WindowsCE\Diagnostics
C:\Program Files\Microsoft Visual Studio 8\SmartDevices\SDK\CompactFramework\2.0\v1.0\WindowsCE\Diagnostics

Enable Network Connection on Windows Mobile Emulators

noreply@blogger.com (Yasin Hasan Karanfil) — Fri, 05 Mar 2010 15:04:00 +0000

If you have trouble with connecting to the internet with emulator, and you also tried Active Sync or Windows Mobile Device Center, there is a better way to do it, which worked perfectly for me.

Source:

http://www.xdevsoftware.com/blog/post/Enable-Network-Connection-Windows-Mobile-6-Emulator.aspx

Steps How I Enabled Internet Connection on the Emulator:

- Downloaded and install Virtual PC 2007 (this is because it has to install some driver for the network card to work for the emulator)
- Open Windows Mobile Device Center and allow DMA connections.
this can be done by going to Mobile Device Settings ->Connection Settings -> Allow Connections to one of the following -> Select DMA
- Opened Visual Studio and opened my mobile app
- In the toolbar selected Device Options Icon (located next to dropdown with the emulators to select from)
- Under Device Tools -> Devices I selected my Windows Mobile 6 Pro Emulator then clicked on Properties
- Clicked Emulator Options
- Select the Network Tab
- Checked the first box (enabled NE2000 PCMCIA network adapter and bind to:)
- Selected the name of my network card
- Ran the emulator by running the application
- Went to Connection Settings in the Emulator
Start -> Settings -> Connections Tab -> Connections -> Advanced Tab -> Select Networks -> Choose My Work Network for both drop downs

That should do it to get internet going on your emulator. Quite a few steps to get on the Internet, but oh well.

Creating Windows Mobile CAB Files Programmatically

noreply@blogger.com (Yasin Hasan Karanfil) — Fri, 05 Mar 2010 14:58:00 +0000

There is an easy way to create CAB files programmatically is to create Smart Device Cab Project in Visual Studio. If you check the Debug output you will see there is a command like this

"C:\Program Files (x86)\Microsoft Visual Studio 8\smartdevices\sdk\sdktools\cabwiz.exe" "C:\Users\aradiomy\Documents\Visual Studio 2005\Projects\Program\ProgramKurulum\Release\ProgramKurulum.inf" /dest "C:\Users\aradiomy\Documents\Visual Studio 2005\Projects\Program\ProgramKurulum\Release\" /err CabWiz.log

You can edit the *.inf file and call this command from a script or your program.

Google App Engine Java UTF-8 Character Encoding Problem

noreply@blogger.com (Yasin Hasan Karanfil) — Sun, 17 May 2009 15:44:00 +0000

There is a problem about Google App Engine Java Encoding settings. You have to change the Google App Engine's Javac Compiler Encoding.

http://groups.google.com/group/google-appengine-java/browse_thread/thread/1345bf330766d8be/

The easiest way to do it is add an UTF-8 argument to javac.exe. You can use this simple tool.

http://www.karanfil.info/blog/javac.exe

Rename the default javac.exe to javac1.exe, and copy this tool to same folder. (For example : C:\Program Files\Java\jdk1.6.0_12\bin\javac.exe)

Netbeans Türkçe Versiyonu Gelişmeler

noreply@blogger.com (Yasin Hasan Karanfil) — Thu, 07 May 2009 13:01:00 +0000

Merhaba Arkadaşlar,

NetBeans Türkçe Yerelleştirme Takımı olarak Java SE kümesini (cluster)
çevireceğiz. [1] sayfasında da görüldüğü gibi öncelikli hedefimiz Java
SE kümesini tamamlayabilmek.

Daha sonra C/C++, Ruby, PHP gibi kümelerin de yerelleştirmesini
yapabileceğiz. Tek yapmamız gereken şey CTI'daki projeye bu kümelerin de
eklenmesini istemek olacak.

Peki Java SE kümesini neden seçtik? Çünkü yerelleştirmek için oldukça
büyük bir küme ve zaman alacak.

Java SE yerelleştirmesine katılmak isteyen arkadaşlar listeye ya da bana
özelden e-posta yollayabilirler mi? Çünkü CTI hesabının açılması ve bu
hesabın projelere tanıtılması gerekli.

[2] sayfasındaki listede kümelerin detaylarını bulabilirsiniz. NetBeans
6.5 sürümü için kümelerin listesi [3] sayfasındaki gibiydi.

[1] sayfasında görülebileceği gibi Platform yerelleştirmesinde %100'e
ulaştık. Hâlâ eksiğimiz ya da yanlış olarak çevirilmiş kısımlar
bulunabilir. CTI [4]'a girip (hesabınız yoksa bile) çevirilere gözatıp
hataları e-posta listelerimize yazabilirseniz, çok seviniriz.

Bu vesileyle büyük katkı sağlayan Orhan (orhanbalci) ve Yasin
(yasinkaranfil)'e çok teşekkür ediyorum.

En kısa süre içerisinde de wiki [5] sayfamızı 6.7 sürümü için
güncelleyeceğim.

Herhangi bir öneri ya da görüşünüz varsa lütfen çekinmeden bu e-postayı
yanıtlayın.

Sevgiler,

iPhone SDK installation on 10.5.2 Leopard

noreply@blogger.com (Yasin Hasan Karanfil) — Tue, 21 Apr 2009 11:48:00 +0000

Getting the FINAL SDK to run on a 10.5.2 Leopard box.

1) Install the Iphone_SDK_Final DMG file. It won't let you install the Iphone parts; no worries.

2) Open the Packages folder on the DMG and install all the packages labeled IPHONE and "DeveloperDiskImage".

3) These packages will install into /Platforms, but we need them in /Developer/Platforms. Use Finder, Terminal, whatever, to move these files over.

4) You should at least have a working Iphone Simulator. You'll be able to write code and run it on your PC.

J2ME repaint() problem

noreply@blogger.com (Yasin Hasan Karanfil) — Tue, 17 Feb 2009 11:35:00 +0000

If you are confused about Canvas repaint() method does'nt calls paint() method. And you also tried
                // serviceRepaints();
                // Display.getDisplay(Midlet.instance).callSerially(this);
                and still doesn't works.

Here is the solution;

Copy the paint() method and rename it customPaint(). In the code where repaint doesn't works, replace repaint() with customPaint().

And

In Netbeans

Tools - Java Platform Manager - J2ME - WTK - Open Preferences - Performance
Display refresh -> Select Immediate

Hopefully it works out.

Google, ücretsiz çeviri hizmeti olan Google Translate servisine bugün Türkçe dilini de ekledi.

http://translate.google.com/

Web sitelerini, yazılarınızı türkçeye çevirebilirsiniz. Çevirilmiş arama, sözlük, Toolbar Translate kısımlarına henüz türkçe desteği eklenmemiş.

Ayrıca güzel bir hizmet de web sitenizin diğer dilere otomatik olarak çevirilebilmesi için sayfanıza script yerleştirebiliyorsunuz. Böylece türkçe sitenizi ziyaret eden kullanıcılar kendi dillerini seçerek sayfalarınızı gezebiliyorlar.

Dr. Barrett'in ODTÜ'deki Konuşması

Intel Yönetim Kurulu Başkanının Dr. Barrett'in konuşması:

Dr. Barrett konuşmasında ilk olarak internet tarayıcıları konusunda bir devrim yaratan Netscape'den bahsetti. Daha sonra ilk çıkardığı hizmeti "ağ dizinleri (web directory)" ile bir anda büyük bir ilgi gören Yahoo!'yu örnek verdi. Son olarak da arama motoru dünyasında bir çığır açan Google konusunda konuştu.

Bu üç fikir, yani Netscape, Yahoo! ve Google hakkında, "Bu fikirler insanların hayatlarını değiştirdiler. Ancak bu fikirlerin herhangibiri, ar-ge faaliyetlerine yıllık 7 milyar dolar harcayan Microsoft'ta veya yıllık 6,5 milyar dolar harcayan Intel'de olsaydı kuvvetle muhtemel proje yöneticisi ya da onu geçti diyelim daha üst düzey bir yönetici tarafından iptal edilirlerdi" dedi.

"Bu fikirlerle insanlar ilk çıktıkları zaman nasıl para kazanacaklarını bilmiyorlardı. Google 1998'de kuruldu, 2001'de ancak para kazanmaya başladı. Bir şirketin varlığını sürdürebilmesi için para kazanması gerekir, bu nedenle bu fikirler ve buna benzer diğer fikirler eskiden ve şu anda büyük şirketlerin çoğunda nasıl para kazanacakları belli olmadığı için iptal ediliyorlar" dedi.

Dr. Barrett, dinleyicilerin dikkatlerini daha sonra bu üç fikrin ortak bir noktası olduğuna çekti ve konuşmasına şu sözlerle devam etti, "Bu üç fikir de üniversitelerde doktora ve master yapan araştırmacıların üniversite olanaklarını kullanarak ortaya koydukları projelerdi. Üniversitelerin olanakları yetersiz olsaydı bu fikirler hayata geçirilemeyecekti. Araştırma yapmaya önem veren üniversiteleri bu nedenden ötürü önemsiyoruz".
