Hi all, I need org.apache.commons.lang library for some useful methods (this case is StringEscapeUtils). But org.apache.commons is unavailable and I don't know why. I loaded library with tLibraryLoad, this is lib is in the list, but TOS doesn't recognize "org.apache.commons.lang.StringEscapeUtils.escapeJava". I tried commons-langx.xx.jar.... end org.apache.commons.lang3x.xx.jar, but nothing. I tried to create a custom routine and and manually import, but TOS show me only org.apache.log4j..... Restarted TOS and nothing. Any ideas? Is this correct? P.S. I found it in module view, as an installed library.
