Updating Tomcat to 7.0.91 breaks pages

[Maximilian Völker]

With the latest update to tomcat, a stricter parsing of function signatures was introduced: Correct parsing of XML whitespace in TLD function signatures that incorrectly only looked for the space character. (See Changelog)

By this, some pages respond with error 500 and in the bibsonomy error log you can find exceptions like org.apache.jasper.JasperException: Method "containsResourceClass " for function "containsResourceClass" not found in class "tags.Functions"

Removing any whitespace in function signatures in BibSonomy / bibsonomy-webapp / src / main / webapp / WEB-INF / taglibs / mytaglib.tld solves this issue.

Example:

<function-signature>String getPath (java.lang.String)</function-signature>

to

<function-signature>String getPath(java.lang.String)</function-signature>

See also this forum post.

(We're using PUMA, but I suppose the code comes from the BibSonomy-Project.)

Please note that starting with 3.8.17 you need at least tomcat 8 (we recommend tomcat9) to run the bibsonomy/puma app

Thanks for fixing and for the tomcat hint!
