Re: [Php-java-bridge-users] Help

Thank you very much Jost,

I solved the problem just last night and you were right. I could catch the two Runtime Exceptions before the execSelect() call using the java_values() function. The problem was in the arguments format I was using. 

You are right about the while loop. Here, the java_values function saved me again. It's probable that it is not the right way to solve it, so I will follow your advices.

Either way I just starting and I think PHP / Java Bridge is a magnificent tool. I hope not to bother too often.

Thanks again.
