class not foundexception: oracle.jdbc,driver.OracleDriver - ojdbc

I wrote a code and got this error, then I searched it in Internet and all answers were about adding jdbc literary, I did it 8n several ways according others guidance in Internet but Ithe didn't work.

you have written wrong path "oracle.jdbc,driver.OracleDriver" , replace this with
"oracle.jdbc.driver.OracleDriver" because a path never contains a seprater.

What is the RKUIManager?

I get an error with RKUIManager, or more precisely:
Could not invoke RKUIManager.manageChildren
It appears for example when I'm using firebase with React Native and try to set a reference in the constructor of a component with a prop. For ex:
messagesRef = FBRef.child("Messages").child(this.props.currentMeetingID)
If I change it to the following it works, and yes, I have checked if this.props.currentMeetingID is a legitimate value.
messagesRef = FBRef.child("Messages").child("123456789")
I can't seem to locate the problem nor reproduce it perfectly. I'm just trying to figure out if it's my machine or some kind of bug elsewhere.
Right now I'm just looking for info about what RKUIManager actually is.
If I nullcheck this.props.currentMeetingID I fix it, easy fix but nowhere to be found on the internet so I'll leave it here for anyone passing by. Probably me in a couple of weeks...

How can I except some kind of errors on sass-lint?

I've been refactoring the CSS with sass on our project.
So I wanna fixing by the sass-lint, but it's so hard cause it have so many errors.
For example, 'Avoid using id selectors' or 'Selector 'mainFooter' should be written in lowercase with hyphens' like that.
These things can't be fixed now.
So I've found the document below, but they have only about 'BorderZero', 'StringQuotes' and 'all'.

Oh, I found it!

Thanks :)

Simian multiple excludes option

I use Simian to analyze the duplicate codes in my c# project.
But I want to exclude two kind of situations.
One is unit test files shouldn't be analyzed, the other is auto-generated file (such as Microsoft.Moles auto produces m.g.cs files)
My arguments are fine as following when I only have one kind of file excludes
-formatter=vs:c:\temp\SimianResult.log -language=cs $(SolutionDir)//*.cs -excludes=/*Test.cs -threshold=15
But when I add the second situtions, I don't know how to put them together, I search it on the web ,but cannot find samples, even the offical site http://www.harukizaemon.com/simian/ doesn't show it.
I try the following combination but all fails
(1)... -excludes=/*Test.cs,/*m.g.cs -threshold=15
(2)... -excludes=/*Test.cs;/m.g.cs -threshold=15
(3)... -excludes=*/Test.cs */*m.g.cs -threshold=15
Does anybody know how to solve it ?
thanks
My co-worker has try the correct syntax for me and it works.
The key is your have to put the keyword "excludes" twice. So the answer of my question is
-formatter=vs:c:\temp\SimianResult.log -language=cs $(SolutionDir)//*.cs -excludes=/Test.cs -excludes=*/m.g.cs -threshold=15

simplehtmldom 500 error

I saw that there are a lot of topics on simplehtmldom, but no one's problem seems to be mine- specifically, that it just 500s, even on the examples provided. I've found that I can include the file without an error, but if I then try to use file_get_html, it 500s. The only thing I found in the manual about installation is a possible problem with allow_fopen_url, which I do.
Something I'm missing?
Seems like too long since you asked this question, but since I came across this trying to solve this problem myself, I thought I'd post what worked for me.
I solved this problem by changing file_get_html to file_get_contents. Since I wanted to use the 'find' feature in simple_html_dom, I had to then convert the string to an object:
$string = file_get_contents(http://thedeadfallproject.com/)
$object = new simple_html_dom();
$object->load($string); // Load HTML from a string
