• Create Word/RTF file with table of contents from Java

  - by Glen

  Hi, I want to create a Word or RTF file with a table of contents (with links to each section) from Java. From my understanding, iText & Apache POI do not support generating a table of contents. Some clients of the app still use older versions of Word, so I need a library that supports the older Word doc format. Does anyone know how I can do this? Thanks, Glen

• List MySQL enum in Java

  - by Pieter

  Is there a way to get all possible values from a MySQL enum column? The MySQL documentation says the MySQL enum type is returned as a Java String, so I basically would like a way to get all possible strings I can pass when querying a table with such an enum. I couldn't immediately find anything when I was looking through the metadata returned for such a column, but since enum isn't standard SQL, I'm not sure it's even possible... any suggestions?

• Java class object from type variable

  - by Alexander Temerev

  Is there a way to get Class object from the type variable in Java generic class? Something like that: public class Bar extends Foo<T> { public Class getParameterClass() { return T.class; // doesn't compile } } This type information is available at compile time and therefore should not be affected by type erasure, so, theoretically, there should be a way to accomplish this. Does it exist?

• How to sanity check a date in java

  - by Bloodboiler

  I find it curious that the most obvious way to create Date objects in Java has been deprecated and appears to have been "substituted" with not so obvious to use lenient calendar. So... How do you check that a date given as a combination of day, month and year is a valid date? For instance a date 2008-02-31 (as in yyyy-mm-dd) would be invalid date.

• Java Deflater strategies - DEFAULT_STRATEGY, FILTERED and HUFFMAN_ONLY

  - by Keyur

  I'm trying to find a balance between performance and degree of compression when gzipping a Java webapp response. In looking at the Deflater class, I can set a level and a strategy. The levels are self explanatory - BEST_SPEED to BEST_COMPRESSION. I'm not sure regarding the strategies - DEFAULT_STRATEGY, FILTERED and HUFFMAN_ONLY I can make some sense from the Javadoc but I was wondering if someone had used a specific strategy in their apps and if you saw any difference in terms of performance / degree of compression. Thanks, Keyur
