Our department has inherited code that uses Apache PDFBox 1.8.x or earlier and we are in the process of trying to migrate it to Apache PDFBox 2.0.x. I have versions of the last three major versions (1.7.x, 1.8.x, and 2.0.x) that I've looked to for guidance as well as the Migration to PDFBox 2.0.0 and the PDFBox Jira Board.
We have a class that extends PDFStreamEngine and there used to be a constructor that took a Properties object and used that to populate the internal operators field. I don't see any comparable features to initialize this field and all output is dropped because there are no registered operators.
Is there a recommended way to set these operators or do I just need to borrow the old properties processing code from 1.8 and add it to my extended class?

I am migrating from jdk8 to jdk11 and hence trying to use chronicle-queue v5.
In ChroincleQueue version 3 we had dedicated methods for creating SourceQueue and SinkQueue.
But I am finding it little difficult to implement the same with ChronicleQueue v5.
I am trying to follow this. In the doc they have mentioned use of ReplicatedQueue and ReplicatedQueueCfg classes. I looked into different classes of all the other packages of Chronicle but didn't find any of these classes.
How can I implement replication using ChronicleQueue5 ?
I need to use both quartz-1.8.6 and quartz-2.x.x dependencies in the same maven 3 project.
The reason for keeping 1.8.6 is that it's used by a large amount of code and new features are considered to written in spring, and in this case quartz-2.x come into play.
So the question is: how can I keep both these dependencies in the same project ? Maybe add some exclusions?
do you really need to use both of them at the same time
generally the classes may be deprecated. but usage will still be allowed.
You see whole idea of using maven is to avoid multiple jar of same API.
I will suggest code changes and completely using quartz 2.x API.
I was getting similar issue when I used lucene and was switching from 2.2 to 2.8/3, there were not just deprecated methods but many lucene classes were removed i the 2.8 API. I still ended in upgrading the API than using duplicate dependent jars
The kernel of Dojo is Base, an ultra-compact, highly optimized library
that provides the foundation for everything else in the toolkit.
I'm quite new to dojo toolkit and confused in the above context of kernal of dojo as whether they are meaning dojo.js file or all the file inside the dojo directory?
Can some explain me what is really called Base in Dojo?
dojo/_base is a subset of the dojo package.
At this point, it exists mostly for legacy reasons, but it was originally created as a list of what was included in the built version of dojo.js by default.
The idea was to create the same version of dojo.js, and for CDNs, without immediately needing to load additional resources.
With the emergence of AMD, _base has outlived its usefulness and is a legacy thing that will go away with Dojo 2.
What is the last version of nhibernate that supports .Net Framework 2 ? and is there a big difference between dealing with it and dealing with last version that supports .Net 3.5 ?
Note:
The series NH2.1.x is the last whose
target is .NET2.0
NHibernate 3 Alpha (full .NET Framework 3.5 support):
With the 3.0.0 release, NHibernate
includes support for LINQ, along with
additional features such as:
Along with a long list of bug fixes
and improvements, it has several new
features including a new strongly
typed criteria API called QueryOver;
lazy loading of columns; alias
delimiting in generated SQL; and
support for DetachedCriteria within
IStatelessSession. The new release
also brings improved support for LINQ,
overcoming the HQL limitations of the
previous provider.
Upgrading users should be aware that
one of the fixes means that null
values in dictionaries are no longer
silently ignored, which has the
potential to break existing
application code.
I'm migrating the data layer of our application to NH version 2.1.0 (from 2.0.1) and noticed the use of LinFu. I discovered that framework and want to use it in other pieces of the application, especially I want to use the LinFu.Reflection.dll, which requires a reference to LinFu.DynamicProxy and here comes the trouble, the 1.0 final version of LinFu that I can find on google.code is not the same version used by NHibernate itself. Do I need to rebuild NHibernate.ByteCode.LinFu.dll changing the reference to the available version? If not, what else?
I have faced the same problem a few days ago. There's a tool named ILMERGE that merges .NET DLL-files, and that way you should be able to have several versions of the same DLL in your application.
Unfortunately I haven't tested the tool yet, I didn't get around to it, but I'll test in the next week.
But Rhino Mocks for example, has a binary with all dependencies included: http://ayende.com/projects/rhino-mocks/downloads.aspx, so it seems doable.
