java - Failed to connect hypersonic(HSQLDB) DB on Apache 7.0 -

-

i have project in eclipse defined 'dynamic web project' on apache-tomcat 7.0 server.
need connect hypersonic db (hsqldb) in of java classses.

the code i'm trying make simple: 

private connection getconnection(){     connection conn;      try {            class.forname("org.hsqldb.jdbcdriver");         conn = drivermanager.getconnection("jdbc:hsqldb:hsql://localhost","sa","");         return conn;     }      catch (exception e) {         e.printstacktrace();     }        return null; }

i added hsqldb.jar lib library located in project , defined in java build path on eclipse.

the problem i'm getting error:

java.lang.classnotfoundexception: org.hsqldb.jdbcdriver     @ org.apache.catalina.loader.webappclassloader.loadclass(webappclassloader.java:1722)     @ org.apache.catalina.loader.webappclassloader.loadclass(webappclassloader.java:1573)     @ java.lang.class.forname0(native method)     @ java.lang.class.forname(unknown source)     @ root.login.getconnection(login.java:75)     @ root.login.dopost(login.java:35)

so cannot find org.hsqldb.jdbcdriver class reason.
have made configuration many times before that, , went well.

funny story:
managed have simple java project main function , function on same configuration, , went on exact same machine.

  • what can in order find class?
  • is there more information need tell make clearer?

in web application, have add hsqldb.jar file web-inf/lib folder of application (or $tomcat_home/lib folder, if have more webapps using it). have in eclipse project's classpath not enough.

mysql - FireDac error 314 - but DLLs are in program directory -

-
i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.

c# - How do I debug "System.DllNotFoundException: The specified procedure could not be found"? -

-
i've got pinvoke wrapper set native dll, time try invoke it, crashes, saying system.dllnotfoundexception: specified procedure not found . things i've checked: the dll in same folder exe. dependency walker shows dll has 1 non-system dll dependency, , it's loaded (successfully) process point. it gives same error no matter function try call into, including dummy function no body. (so points 1 , 3 answer here not apply.) i've used dependency walker ensure functions being exported, same names, including case sensitivity. by point, i'm @ wits' end. how can debug , figure out what's going wrong? error message i'm getting spectacular pile of fail when comes usefulness; doesn't tell me name of procedure can't find. i'd debug first in native application. reasons explain later. put simple console app in same directory c# executable. have console app call loadlibrary , getprocaddress on dll p/invoking. same error occur? ...
