gclib | reusable code for bioinformatics projects | Dataset library

Im very novice at java programming. Running into an error message while trying to make a browser using locally stored GECKOVIEW library. The build does complete but the app crashes. Help would be greatly appreciated because i'm very stuck and it's proven difficult to find information about problems arising with GeckoView.

Error message:

I'm trying to use the default aop proxy provided by Spring, but i'm getting an execption error.

Here is my code: A first class that run the test example.

I have written several small scripts in python and build the binaries using pyinstaller.

When I would build them on my Ubuntu 16.04 machine -- they would run fine on the machine where I build them. But moving the file to a Centos / Redhat 7.4 machine would give me GCLIB and other .so version dependency errors.

• Building the same binary on docker with the same version of Centos would not give these errors.
• If I try running the binary compiled on Centos 7.4 on Centos 6.6 I would get errors again -- But building on Centos 6.6 it would work correctly with Centos 6.6

I have solved the problem using a lower version of Centos to build my binaries for now.

• My specific question is -- In Python, is it a common approach of building the binaries on different OSs based on the target OS that it is intended for (assuming linux targets only) or what I am doing is a hack / bad way of solving this problem?

I am trying to understand how this problem is approached in the standard way.

I used the XADES4j project to sign electronic invoices using JavaSE-1.8 (jre1.8.0_121) 32-bit version + Windows32Bits + eclipse (32-bit Luna) + Gemalto token and it worked well. Now I'm using the Windows64 bit system, I have not changed anything: I installed the JavaSE-1.8 (jre1.8.0_121) 32-bit version, the same version of eclipse (32-bit) and the token Gemalto (gclib. 64bit dll). when running the signature from eclipse I encountered runtime errors at the pkcs11 security provider installation level :

**1. Service usage: when you see a hibernate spring tutorial, they all say that for an entity (e.g. User in my case ) you must have a repository called UserRepository with methods like find, findAll, delete, etc. Normally the UserRepository extends some base Repository interface.

Then you have to add the UserService, which injects a UserRepository.

a. Must I have a UserService interface that is implemented by a UserServiceImpl?From my point of view it adds no value to have this. I can have UserService be a class and use Spring's ability to create proxy using GCLIB instead of JDKInterfaces.

b. Is it correct to write the UserService by copying every method from UserRepository and delegating to the @Autowired repository, and then add any other bussiness method?

c. If my UserService doesn't have any bussiness methods, it just delegates everything to the UserRepository, can I just skip the UserService and access directly the UserRepoisitory from my REST layer?

d. Let's say that I also have an Address entity. The user needs an Address when saving ( it is a one2one mandatory ). Is it ok from UserService to inject both UserRepository and AddressRepository inside of it, set up relations there and then call save on each repository? ( don't want to use cascading persist, I want to know how would I do without it since in some situation you cannot use cascading )

2. DTO usage: When you want to read data, you can fetch entities or fetch DTOs directly through JPQL ( or Criteria, I prefer JPQL ).

a. From my point of view, I would always use DTOs instead of entity fetching. It's because, I think SQL is simple, and if i have to think about entities merging, detach, attach , etc, I miss out the entire simplicity of SQL, and ORM becomes an enemy in terms of performance and complexity. So I would use DTO always when I read data and entities when I modify data. What do you think?

b . I want to return all the columns from the User entity. Is it ok to have a UserDTo or I am exaggerating and should just return a User entity? I am 50% - 50% on this.

c. I want to return partially some columns from User. Here I am for 75% DTO and 25% entity. What do you think?

d. I want to return some columns of User and some columns of Address. Here I am 100% for DTO ( although I could just join fetch Address ). What do you think?

Kind regards,

It is possible to delete the prefix "SunPKCS11-"? because always I get a provider whose name is "SunPKCS11-SmartCard" and not "SmartCard" .

this my code :
