Read and search text in HTML - ArrIndOutOfBoundsException: 88

[Seema Sharma]

Hi,
I am searching text from HTML and finding file names. Placing those names to JList. Searching is taking place properly. but java.lang.ArrayIndexOutOfBoundsException: 88 is thrown.

Find the code below:

public String search(JEditorPane editorPane, String word, String arg_strFilePath) {
int countOccurances = 0;
strGetFileName = arg_strFilePath;

try {
reader = new FileInputStream(arg_strFilePath);
} catch (FileNotFoundException e) {
e.printStackTrace();
}

HTMLEditorKit htmlKit = new HTMLEditorKit (  ) ;
editorPane.setEditorKit(htmlKit);
HTMLDocument htmlDoc = (HTMLDocument) htmlKit.createDefaultDocument();
HTMLEditorKit.ParserCallback callback = htmlDoc.getReader(0);
HTMLEditorKit.Parser parser=new ParserDelegator();
try {
//parser.parse(reader, callback, true);
editorPane.read(reader, htmlDoc);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

if (word == null || word.equals("")) {
System.out.println("word == null " );
return null;
}

doc = editorPane.getDocument();
try {
content = doc.getText(0, doc.getLength()).toLowerCase();
System.out.println("Content:\n " + content);
} catch (BadLocationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

word = word.toLowerCase();
System.out.println("word= " + word);
int lastIndex = 0;
int wordSize = word.length();
System.out.println("wordSize= " +wordSize);

while( (lastIndex=content.indexOf(word, lastIndex+1))!=-1)
{
countOccurances++;
}
System.out.println("countOccurances= " + countOccurances);

try {
reader.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

if(countOccurances!=0){
//Gets file name for matched text
getlistElements(strGetFileName) ;
filesMatching = strTemp;
}

return filesMatching;
}

Please let me know why this exception occurs:

Which line in that quoted code is throwing the Exception? I can't see any [] in your code.

[Seema Sharma]

It show exception at line editorPane.read(reader, htmlDoc);

Do i need to use HTMLEditorKit.Parser for reading. I tried using the parser.read() method, but shows errors. Tried the bow code:

  
HTMLEditorKit.ParserCallback callback = htmlDoc.getReader(0);
HTMLEditorKit.Parser parser=new ParserDelegator();
parser.parse(reader, callback, true);

when above code is used for reading HTML, search logic itself doesn't work and same java.lang.ArrayIndexOutOfBoundsException: 88 exception as above occurs, this time at parser.parse(reader, callback, true);

Thanks for reading. Any help is highly appreciated.

Seema

That doesn't help a lot; you haven't shown us which line is causing the Exception.

[Seema Sharma]

Exception is shown at line editorPane.read(reader, htmlDoc);

Thanks in advace,
Seema

[Campbell Ritchie]

None of your code appears to contain any arrays in the first place. What are you passing to the editorPane?

[Seema Sharma]

Campbell,
I am reading large number of HTML files, so exception may be because of that.
Same exception i found in the below link, but did not understand the solution.
Check URL

Please help in uderstanding it.

Thanks in advance,
Seema

Don't know. Sorry. I couldn't understand the other thread either.
