I have linux machine with java installed on it . I have written a program that takes a html and makes a pdf out of using IText . this program is working on my local . I see the same program is not working on the server .
How do i resolve this. I assume that the font is not recognized on the linux machine.
Can some one tell me how to attach the font to the jvm.
I found the issue for this . While writing the PDF file to disk , the encoding of the file was not UTF-8 . When i fixed this , everything started working fine

I was trying to access a file with a java scanner class but always got FileNotFoundException so i tried to output what my current working directory was System.out.println(System.getProperty("user.home"));
and it returned null
Do i have to manually set it somewhere in project settings or are my enviromental paths messed up? How can i fix this?
When you are on Android the traditional 'user.home' property has no specific meaning or equivalent to what it would in a traditional desktop java application. However when running inside an Android runtime you should have access to the 'Environment' class which defines a number of paths to relevant directories.
Take a look at the getDataDirectory() call, which should give you a file object to the correct system path.

We have the below java command which was running and stopped working all of a sudden,
java –cp "classes:lib/*" xxx.yyy.ppp
The jar is within lib directory and the jar contains the class.
It stopped working all of a sudden and gived the below error,
"Error: Could not find or load main class –cp"
Why is it considering '-cp' as the main class, even though ppp (example) has the main class. Please help me out with this...
You are not using a default hypen before cp as java –cp "classes:lib/*" xxx.yyy.ppp
Use this instead : java -cp "classes:lib/*" xxx.yyy.ppp

I am trying to install Java 7u80 on Windows 10. When I attempt to install it, get this error:
"Error 1324. The path Temp;C: contains an invalid character."
I am not sure what it means or why it is even trying to use a path with those characters in it. I have been trying to do research on this issue and so far found nothing. The solutions I found said that it is caused by a username with an invalid character in it, but my username is CF77. I do not know what to do and am looking for help.
Your TEMP or TMP environment variable is likely bad. That's usually where installation programs find the path to the temp folder. Type command set in a command prompt to see your environment variables. – Andreas
Well you can easily figure out if you watch few you tube video on how to set the path variable in java after installation.
Here is the couple of link-

My code works on my windows 7 machine, however it doesn't work on my windows 8 computer.
I get this error:
java.io.FileNotFoundException: C:\Drawing.jpg (A required privilege is not held by the client)
The code creates a jpg file in C:\ . This is a permission problem with java and windows 8. I gave myself read and write privleges to my c drive but it still doesn't work. Is it there some permission settings that I can change with the JVM?
more code:
String dir = "C:\\Drawing.jpg";
BufferedImage image = componentToImage(component, null);
File file = new File(dir);
file.setWritable(true);
file.setReadable(true);
file.setExecutable(true);
System.out.println(file.canWrite()); //this returns false
ImageIO.write(image, "jpg", file);
I had to disable my UAC in the registry. Even though the UAC was off already
