I am new to JGraphT. I have already run ShortestPathDemo, but I want to use it with osmfile.
I have tried importers in org.jgrapht.nio, but I failed.

I have a script, main.jl, I am trying to run that looks like this:
using Pkg
Pkg.develop(path="path/to/MyPackage/")
import MyPackage as mp
mp.test()
In my function located in "path/to/MyPackage/src/test.jl" I have
function test()
println("test 1")
end
If I run main.jl I see "test 1", however if I keep the REPL open and modify test() to print out "test 2" it still prints out "test 1". What am I doing wrong?
I have found that using the Revise package in Julia helps resolve this issue. All I need to do is add using Revise to the top of the document:
using Revise
using Pkg
Pkg.develop(path="path/to/MyPackage/")
Pkg.instantiate()
Pkg.resolve()
import MyPackage as mp
mp.test()
After that I can make changes to test() and they show up each time I run the script.
Note that I found that this doesnt work unless I put using Revise at the top before I load any of the packages I want to develop into the REPL, meaning that I had to restart the REPL once to make sure that I imported Revise before running any Pkg.develop.
I am facing some troubles while trying to create an IFSFile using IFSFile object from JT400.jar. The problem that I am facing is when the process that calls the JAVA is called by a BATCH user(without login enabled into AS400 machine).
Exception given

Code used:

//Obtain the template path
String templatePath ="/HOME/XXX/auth.txt";
IFSFile templateAuth = new IFSFile(as400,templatePath);
templateAuth.copyTo(fileXML + ".xml");
I have check some opened threads but no results obtained. (find below the threads commented)
JT400 Read File From IFS with user without password
Java IFSFile on Iseries testing over PC
There is any option to generate an IFSFile when the process is called by a BATCH user(note that when the process is called by a user with login enabled, the process is working as expected)
I need something similar to what is done when a JDBCAppender is created, JDBCAppender object allows setUser(null) and setPassword(null) to enable batch users to write into a table.
Thanks all!
I have recently had a similar problem when trying to use CommandCall whilst running under a profile with PASSWORD is *NONE. I (eventually) solved it by using the native Java toolbox at /QIBM/ProdData/Java400/jt400ntv.jar (which happens to be a symbolic link). I didn't have to make any code changes:
AS400 as400 = new AS400();
CommandCall cc = new CommandCall(as400);
String wrkenvvar_cmd = MessageFormat.format("ADDENVVAR ENVVAR('JAVA_HOME') VALUE(''{0}'') REPLACE(*YES)",path);
boolean ok = cc.run(wrkenvvar_cmd);
I hope that helps.
I'm trying to run a powershell script through batch job, I used the following code that works fine in a job :
System.Diagnostics.Process process;
System.Diagnostics.ProcessStartInfo startInfo;
;
process = new System.Diagnostics.Process();
startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.set_FileName("powershell.exe");
startInfo.set_Arguments("D:\\Documents\\OP3_FTP_Upload.ps1");
startInfo.set_UseShellExecute(false);
startInfo.set_RedirectStandardError(true);
process.set_StartInfo(startInfo);
process.Start();
when I use this code in a runbasebatch class, I have the following errors:
Failed to request the permission of type 'InteropPermission'.
Unable to create object 'CLRObject'
So I try to use the following to solve my permission problem:
Set permissionSet;
InteropPermission interopPermission;
;
interopPermission = new InteropPermission(InteropKind::ClrInterop);
permissionSet = new Set(Types::Class);
permissionSet.add(interopPermission);
CodeAccessPermission::assertMultiple(permissionSet);
...my first code example
CodeAccessPermission::revertAssert();
When I execute my batch job , I have no error message but nothing happens. The path is correct, the script also (parms corrects based on AOS)
I think the problem is my way to implement permissionSet and interopPermission classes, I know how to use it in case of CRUD operations on files, but how to use it in case of script execution? Can anyone explain me how (if possible)to manage those classes in my case of use?
Any other ideas to solve my problem are welcome.
This should be enough (in the method doing the CLR calls):
new InteropPermission(InteropKind::ClrInterop).assert();
Otherwise try to debug.
I'm using the function sqlite3_prepare_v2 to access to the database but it not returns SQLITE_ERROR( http://www.sqlite.org/c3ref/c_abort.html ).I tried to use another db and it was ok.I made a new db(with navicat) the function returns SQLITE_ERROR...The code is ok,the problem regards the db.I thought to make the new db with the command line but where is saved?Any suggestion?
I have an application that should use an application role from the database.
I'm trying to make this work with queries that are actually run using Subsonic (2).
To do this, I created my own DataProvider, which inherits from Subsonic's SqlDataProvider.
It overrides the CreateConnection function, and calls sp_appsetrole to set the application role after the connection is created.
This part works fine, and I'm able to get data using the application role.
The problem comes when I try to unset the application role. I couldn't find any place in the code where my provider is called after the query is done, so I tried to add my own, by changing SubSonic code. The problem is that Subsonic uses a data reader. It loads data from the data reader, and then closes it.
If I unset the application role before the data reader is closed, I get an error saying: There is already an open DataReader associated with this Command which must be closed first.
If I unset the application role after the data reader is closed, I get an error saying ExecuteNonQuery requires an open and available Connection. The connection's current state is closed.
I can't seem to find a way to close the data reader without closing the connection.
Do you have to use the role for every query?
If not you can use a SharedDbConnectionScope()
using(var scope = new SharedDbConnectionScope())
{
// within this using block you have a single connection
// that isn't closed until scope.Dispose() is called
// (happens automatically while leaving this block)
// and you have access to scope.CurrentConnection
// Do your init stuff
SetRole(scope.CurrentConnection);
var product = new Product();
product.Code = "12345";
product.Save();
// Revert to normal
UnsetRole(scope.CurrentConnection);
}
The problem is that Subsonic executes its reader with CloseConnection.
If I make it not close the connection I can unset the application role after the reader is closed.
May be you can subscribe to the event like this:
Connection.StateChange += new System.Data.StateChangeEventHandler(Connection_StateChange);
And then do some actions according to the new state of this connection:
if(e.CurrentState== System.Data.ConnectionState.Open)
dbworker.ExecuteCommand("EXEC sp_setapprole application, 'password'");
