java - How to load a PDF from a .jar File? -

-

I have created a swing application and it includes a file, help.pdf in .jar File will be When the user selects a help-> user guide from a JNNUTime, then it should load the file in the default PDF viewer on the system.

I have the code to load the PDF, 

  private zero openHelp () {try {java.net.URL helpFile = getClass (). GetClassLoader (). GetResource ("help.pdf"); File pdf file = new file (helpFile.getPath ()); If (pdfFile.exists ()) {if (Desktop.isDesktopSupported ()) {Desktop.getDesktop (). Open (pdfFile); } Else {System.out.println ("Awt desktop is not supported!"); }} And {System.out.println ("File does not exist!"); } System.out.println ("Done"); } Hold (Exception pre) {ex.printStackTrace (); }}   
 This eclipse works in the IDE, however, when I pack it in a jar for other people it does not work anymore.  
 How can I fix this problem?   
 
 
 The problem is that a  file  is not the name of a component of a jar File can be given. What you need to do is to copy the resource from the file system to a temporary file in the file system, and open it using the  file  for the temporary file.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
