https://community.qlik.com/t5/Talend-Studio/org-apache-commons-lang-library-is-missing/m-p/2369278#M132436 Hi all, <BR />I need org.apache.commons.lang library for some useful methods (this case is StringEscapeUtils). <BR />But org.apache.commons is unavailable and I don't know why. <BR />I loaded library with tLibraryLoad, this is lib is in the list, but TOS doesn't recognize "org.apache.commons.lang.StringEscapeUtils.escapeJava". <BR />I tried commons-langx.xx.jar.... end org.apache.commons.lang3x.xx.jar, but nothing. <BR />I tried to create a custom routine and and manually import, but TOS show me only org.apache.log4j..... <BR />Restarted TOS and nothing. <BR />Any ideas? Is this correct? <BR />P.S. I found it in module view, as an installed library.
