java - Problems with Eclipse adding referenced jars to exported jar file -


I want to create a JAR file from a Meven Java project and it wants to add as external jar file in another project I am However I am receiving a NoClassDefFoundError error. 

  thread "main" java.lang.NoClassDefFoundError exception: org / slf4j / LoggerFactory on com.tutelatechnologies.dashboard.DataUsageLogs.Logging.getlogger (Logging.java:10) on com.tutelatechnologies java.lang.ClassNotFoundException: .dashboard.DataUsageLogs.Logging.d on com.tutelatechnologies.dashboard.DataUsageLogsRunner.DUL_TESTER.main (Logging.java:26) org.slf4j.LoggerFactory in Java due to (DUL_TESTER.java:11) on .net.URLClassLoader $ 1.run java.net.URLClassLoader.findClass on java.net.URLClassLoader $ 1.run (URLClassLoader.java:355) (URLClassLoader.java:366) java.security.AccessController.doPrivileged (Native method on) on java.lang.ClassLoader.loadClass (java.lang.ClassLoader.loadClass in classloader (ClassLoader.java:423) sun.misc.Launcher $ AppClassLoader.loadClass (Launcher.java:308) (URLClassLoader.java: 354). Java: 356) ... 3 More   
 jar file is very simple, it only includes wrappers for logging with Log4J and SLF4J I have it blow:  
  import org. Slf4j.Logger; Import org.slf4j.LoggerFactory; Public class logging {public zero E (string msg, class input class) {logger log = loggerfiner Tag (input class); Logs.error (msg); } Public Zero (string message, class input class) {logger log = loggerfinor.logger (input class); Logs.warn (msg); } Public Zero D (String Message, Class InputClass) {Logger Log = Logger Factor Tag (input class); Logs.debug (msg); } Public Zero T (String Message, Class InputClass) {Logger Log = Logger Factor Tag (input class); Logs.trace (msg); }}   
 Now I right-click this project, export - & gt; Java - & gt; Click the jar file then click Exclude all selected folders.  
 Then I go to my new project by right-clicking the jar file on my project, Build Path- & gt; Select Select. Configure Build Path then in the Library tab I click on the "Add external jar" button and link it to my jar file. I add my source code and a Javadock so that I can link it correctly. It looks fine, but when I run it, I get a nochlas defound error. The reason for this is that in eclipse dependency the jar does not seam to add the file.  
 If I add this project to the Java Build path then I can get it to work. But I want it to be a self-contained jar file. It separates when it is logarithtitter. Runs the MetLogger (InputClass); Which is looking for slf4j dependency  
 The following line is the only line used for this test.    logging d. ("Exam", thisClass.class);   
 Can all dependencies be packed into a single jar file and is it properly linked?  
 FYI, I have tried to make it a runner jar, which works fast to work but then the jar file does not know how to link to the log4j.properties file. This file is located in src / main / resources  
 Any help is appreciated.  
 Cheers,

 It looks like a missing jar, not just SLF4J , Rather your code is Based on your folder structure it seems that you are using Maven, is it possible that you have only the Slaf 4 J-API only marked as Test Dependency? You actually  need  that one against (ie, marked as a compilation dependency), but various plug-ins such as logback-classic or whatever you are using. Test dependency may be,  P>

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
