Recently I'm working on this little project with Java EE and I need to use derby database , but every time I go to service->Database and try to connect to my jdbc:derby I get this error :
Unable to connect. Cannot establish a connection to jdbc:derby://localhost:1527//sample using org.apache.derby.jdbc.ClientDriver (java.netConnectException : Error connecting to server localhost on port 1527 with message Connection refused: connect.).
and this exception :

Any ideas how to fix it?
Did you already try the hint from here http://wiki.netbeans.org/JavaDB_grant_permissions
JDK 7u51 comes with some security improvements which are causing problems with starting Java DB on this Java version.
When you try to start DB from NetBeans you will probably get the Exception:
java.security.AccessControlException: access denied ("java.net.SocketPermission" "localhost:1527" "listen,resolve")
The same exception you will get while starting using script /db/bin/startNetworkServer
Because there is no suitable way to fix it on the NetBeans side and this should be fixed on the side of the Java DB.
There are several ways how to deal with this problem. I will mention only the easiest way. You have to start DB manually from command line.
Start Java DB with -noSecurityManager argument.
<JDK 7u51 location>/db/bin/startNetworkServer -noSecurityManager
you need to add start page in project property.
Open Project property. Then choose tab run. Then add your project start page to relative URL text box. Mine is "/index.jsp".
Sorry if i have some mistake in english grammar.

I have jenkins agent running on windows 10 , when i start the agent via jnlp file its connect i can see "Connected" but then Terminated the next second , when I went into the Jenkins/remoting/logs i found out this error , any one can please help what is the issue and why its getting terminated after connection
My windows agent have OpenJDK 1.8.0
For Jnlp I am using open web start
Jenkins is of latest version 2.318 on agent and master
My master is of linux
Following steps I already tried
I updated my agent JDK to JDK11 but no success so I just downgrade it , i tried to restart/reboot but nothing can helped
Please any jenkins expert can help me with this
Incase any one in future might search for this here is an answer to that problem
The problem does not lies within the jenkins agent or jenkins master but it is the problem with jnlp launcher as with Open web start
When I tried to connect my agent via cmd running command and passing agent.jar it connects to my master and works fine
so any one in future ever encounter problem like this dont touch or change your jdk setting for master or agent but tried to figure out the security / certificate settings of java web start or Open web start whatever you are using
Thanks
For windows node only
There are some dependecies, keep them at same location (dependecies)
You can create the service manually if you have reference. or follow the below steps:
create service using below command:
sc create "service_name" binpath= "path to jenkins-slave.exe" start=auto
Open RUN, type regedit --> this will take you to registry editor.
on editor find your service:
HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> Services -> jenkins_slave (name is same as step 1)
Click on service name and edit Object name (put a user that has access to this machine) -- save
open services.msc and open jenkins_slave properties --> Logon --> enter password for user put in step 4.
start the service -- boom jenkins node is connected :D
I am trying to read a file stored in my computer from the app engine project which I am debugging in eclipse. But I am getting security exception with the following error:
java.security.AccessControlException: access denied ("java.io.FilePermission" ""D:\PROJECTS\LocBiz-AppEngine\war\Key\locbiz_key.json"" "read")
at java.security.AccessControlContext.checkPermission(Unknown Source)
at java.security.AccessController.checkPermission(Unknown Source)
at java.lang.SecurityManager.checkPermission(Unknown Source)
How do I read the file?
Put the files you want to read on the classpath and use the class loader to read them in
Foo.class.getResource("myfile");
A Java App Engine application's access to the classes in the Java standard library is limited to the whitelisted classes.

I tried to put a java.policy.applet file with permission granted for reading but it doesn't work.
I need a quick way to solve this problem. I have to specify that for making this applet I used java 6.
You said you want to read a file on the server, but the exception is caused by trying to read a file on the client (the machine that is running the applet).
You cannot read files from the server directly. You need to access them via HTTP or put them into the applet's jar file and load it from there.
