    <p>I want to revisit an old question of mine about in-memory "compilation" of classes. Since about 1/2 a year have passed since I asked (and was somewhat answered), I'd like to re-raise the issue and see if something new would come up (so no, I don't consider this a duplicate).</p> <p>The old question can be found here: <a href="https://stackoverflow.com/questions/616532/on-the-fly-in-memory-java-code-compilation-for-java-5-and-java-6">On-the-fly, in-memory java code compilation for Java 5 and Java 6</a> - I suggest reading it (and the answers) before answering this question.</p> <p>I'm quite content with beanshell doing the heavy work of evaluating string of a java class to an actual Class object. However, beanshell has been standing on version 2.0b4 for ages now and its limitations (no constructor, not even default; no generics, no for-each, no enums...) are annoying.</p> <p>Reminder - this is to be used as a debugging interface, so performance considerations are negligible. However, I can't have server restarts, can't send class files to the location and JSPs are a very bad choice for me (I won't go into reasons here). Also, the end product must be a Class (or an Object of that class) so I could pass it around.</p> <p>Some limitations: I can't have a JDK, so no javax.tools.JavaCompiler. I can't have JSPs since I don't have tomcat or other "real" web container. Java 5 syntax support would be great, especially generics, enums and parameterization. Support for default constructors would be very nice.</p> <p>Any ideas?</p> <p>Edit 1: I just found out that there is a round-about way of having constructors in beanshell - however you have to declare them "public void XXX(){...}" instead of the usual way "public XXX(){...}".</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
