java - Accessing external URL resources in iText -

-

i'm working on jsf 2.0 project using mojarra, primefaces , tomcat 6.x, in front have apache http server.

i created web form can select pdf files want merge. these files external of war in directory under apache httpd's control. use itext 2.1.7 merge pdf files.

at moment i'm accessing files follows:

pdfreader reader1 = new pdfreader(new url("file:///appli/vignette/vcm/inst-vgninst/docroot_cdc" + file));

however, want access them http:

pdfreader reader1 = new pdfreader(new url("http://centos" + file));
  • centos name of server, webapp deployed.
  • file string variable "/folder/folder1/file.pdf"

this fails. url http://centos/folder/folder1/file.pdf accessible normal webbrowser.

what's wrong , how can fix it?

the pdfreader apparently can't work directly urls point external resource. if intend work url rather file or fileinputstream, best bet use url#openstream() return inputstream pdfreader. has namely constructor that.

pdfreader reader1 = new pdfreader(new url("http://centos" + file).openstream());

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,
