I have SQL expression for Postgres. And i want to get Abstract syntax tree to manipulate this from Java program.
I have found sqlite-parser (find it google, please, I have not enough reputation) from code-school but it`s in develop.
So, do you know another parsers that could execute from Java program ? If it is possible, write almost stable parsers, please.

I have a service written in python.
This service uses DataFrame from pandas.
The thing is that it (the service) should be translated to Java.
For that I need a similar library in Java. (or is there other way to achieve this?)
I would like to know what are some options for this.
Till now I have joinery library
Besides joinery you could also take a look at tablesaw library. Here is link to a brief tutorial: https://jtablesaw.github.io/tablesaw/gettingstarted

I would like to know the best way to generate reports in java. I have written a small code in java which reads data from my csv file and printing in console. how can i pass this data to my HTML reports.
Thanks in advance
The two options I would consider for creating an HTML representation of your data are Apache Velocity & Freemarker. Both of these are easy to use template engines that separate the generation & formatting of the output from the Java code which I find improves maintainability.

I would like to create CMS in JavaEE. I want use graph database. Which graph database is good for this purpose? What do you recommend? I seek free/open source graph database.
I can personally encourage you to use neo4j - http://neo4j.com/. It's new, quite simple, easy to use on Java and has quite good documentation. Although be aware of some minor issues (like an application crashing occasionaly when used heavily).

I am working on a big project with a complex codebase written in java. I want to understand a particular piece of code and i thought getting a sequence diagram of the entry point method would give me a good idea. I use intelliJ and i looked for a plugin which could do this and i found 'SequencePlugin' but unfortunately it is not working in intelliJ 8.1.4. Can i achieve what i am trying to in any other way? Is there a standard approach to follow when trying to understand a complex codebase other than by debugging?

Is there any program/Tool , to compare the individual xmls' or two folders with xml's.
I know I can use Araxis / XMDiff from command line or use scripting to get the report.
What I'm looking for is to exclude some of the Xpath while comparing , and I want to do this from command line , but not from GUI.
If there is no tool I'll have to write a tool in java
I think Beyond Compare 3 has a CLI - http://www.scootersoftware.com/.
I'm still using version 2, it's the best comparison tool around in my opinion.
