I was facing the same issue  I was missing DriverManager registerDriver   call  before getting the connection using the connection URL and user credentials   It got fixed on Linux as below   DriverManager registerDriver new org apache derby jdbc ClientDriver     connection   DriverManager getConnection  jdbc derby   localhost 1527  tmp Test DB Name   user  pass     For Windows   DriverManager registerDriver new org apache derby jdbc ClientDriver     connection   DriverManager getConnection  jdbc derby   localhost 1527 C  Users Test DB Name   user  pass

For me  DriverManager registerDriver new org apache derby jdbc EmbeddedDriver       helped  In this way  the DriveManager does know the derby EmbeddedDriver  Maybe allocating a new EmbeddedDriver is to heavy but on the other side  Class forName needs try catch doSomethingIntelligentWithException that I dont like very much

Had the same  and it was solved by running with the classpath defining the derby jar location  java -cp  lt path-to-derby jar gt   lt Program gt  To be more precise  java -cp  quot lib     quot  Program Where    includes the current directory  And the lib   does not include the jar extension  lib   jar

It s also possible that in persistence xml  EmbeddedDriver was used while the jdbc url was pointing to Derby server  In this case just change the url to pointing a path of database

If your using embedded Derby you need Derby jar in your classpath

Encountered the same problem  I was doing something like  connect  jdbc derby   localhost 1527   databases db1  Replacing the path with the absolute path fixed this problem  connect  jdbc derby   localhost 1527  Users ayush99 databases db1   In summary  Avoid using   or any such variables in the path of existing database

The JDBC DriverManager can t find any suitable Driver for the given connection URL  Either the JDBC driver isn t loaded at all before connecting the DB  or the connection URL is wrong  Since the connection URL looks fine  I bet that the driver isn t loaded at all  You need to load the driver during application s startup before connecting the DB  For Apache Derby  the driver class name is org apache derby jdbc ClientDriver  So   Class forName  org apache derby jdbc ClientDriver

java sql SQLException  No suitable driver found for jdbc derby   localhost 1527    This exception has two causes    The driver is not loaded  The JDBC URL is malformed    In your case  I d expect to see a database name at the end of the connection string  For example  use create true if you want the database to be created if it doesn t exist    jdbc derby   localhost 1527 dbname create true   Databases are created by default in the directory where the Network Server was started up  But you can also specify an absolute path to the database location   jdbc derby   localhost 1527  home pascal derbyDBs dbname create true   And just in case  check that derbyclient jar is on the class path and that you are loading the appropriate driver org apache derby jdbc ClientDriver when working in server mode

You may be missing to start the Derby server  Once a derby server starts  it starts listening to default port 1527   Start script is located as below   Windows        lt DERBY INSTALLATION DIRECTORY gt  bin startNetworkServer bat   Linux        lt DERBY INSTALLATION DIRECTORY gt  bin startNetworkServer

I just bumped into this problem  tried all above suggestions but still failed  Without repeat what have been suggested above  here are the things I  you  may be missing  In case you are using maven  likely you ll state the dependencies i e    lt groupId gt org apache derby lt  groupId gt   lt artifactId gt derbyclient lt  artifactId gt   lt version gt 10 10 1 1 lt  version gt    Please be careful with the version  It must be compatible with the server instance you are running   I solved my case by giving up on what maven dependencies provided and manually adding external jar from   JAVA HOME  db lib   the same source of my running server  In this case I m testing using my Local   So if you re testing with remote server instance  look for the derbyclient jar that come with server package
