This is not a general problem but only with BD2, so inevitably a problem of jar. 
         
 
          
                       I thought the problem revolved around 3 jar DB2 (db2jcc4.jar, db2jcc_license_cisuz-6.1.0.jar, db2jcc_license_cu-6.0.0.jar) and I ended up finding the solution. 
                        
                         
                          
                           
                            
                             
                              
                               
                                
                                 
                               
                              
                             
                            
                           
                          
                         
                        
                      
 
                      
                                 At work I go through a proxy and talend can not install its external archives itself
I download them myself (on https://talend-update.talend.com/nexus/content/repositories/libraries/org/talend/libraries/) and point to it when talend asks me.
 
                               I download them myself (on https://talend-update.talend.com/nexus/content/repositories/libraries/org/talend/libraries/) and point to it when talend asks me.
 
                             But for db2jcc_license_cu, Talend asks me the 6.0.0 or the repository Talend only offers 6.1.0, when i 
                              choose it Talend accepts it but I have this error 
                             . 
                              
                               
                                
                                 
                                  
                                   
                                    
                                     
                                      
                                       
                                        
                                         
                                          
                                           
                                            
                                             
                                              
                                               
                                                
                                                 
                                                  
                                                   
                                                    
                                                     
                                                      
                                                       
                                                        
                                                         
                                                       
                                                      
                                                     
                                                    
                                                   
                                                  
                                                 
                                                
                                               
                                              
                                             
                                            
                                           
                                          
                                         
                                        
                                       
                                      
                                     
                                    
                                   
                                  
                                 
                                
                               
                              
                            
 
                            
                                       I was able to retrieve an older jar via a colleague who talend worked well with the DB2 component, jar of 2015 apparently ... and I do not have the error anymore !
 
                                      
 
                                       
                                                 I think you should put this jar 6.0.0 on Talend-update.
