Jiwa

I am trying to use Jiwa from a stand alone application and then run a Crystal Report to produce a pdf, when the code attempts to load the report Crystal is throwing an exception to do with not finding crpe32.dll, I have noticed that in the Jiwa directory there is a program files directory with a structure and Crystal DLLs is that because Jiwa is using some sort of application assembly resolver to ensure that crystal will works?

No, we don't use a custom assembly resolver in order to locate the Crystal assemblies - our custom resolver is only there for plugin assemblies to be able to locate Jiwa assemblies (as plugins are loaded from the ProgramData folder).

We just use the Crystal installation MSI package in our own installer, which installs Crystal to the GAC and our application references the assemblies in the GAC. The Crystal MSI adds registry entries which are essential for Crystal to work - you cannot just copy Crystal assemblies - and that's the reason why we had to remove support for Azure App Service hosting the Jiwa REST API - even loading a Crystal assembly will fail if those registry entries are not present.

I don't know why there are Crystal assemblies in the Jiwa directory - that could be a mistake... I've checked and we definitely use the GAC assemblies and copy local is false for those references to Crystal assemblies.

What version of Crystal is Jiwa on at present, I am thinking it could be the vs version against runtime that is causing the problem?

SP22 (assembly version 13.0.22.2668)

Thanks Scott that might be the problem I pit down SP27 and the run times related to that, which might be where the issue is coming from.

That would be for Jiwa 07.02.01, yes?

The version of Crystal may change from release to release of Jiwa - we generally avoid changing the versions of 3rd party components when possible, but we do change some from time to time - for instance Jiwa 07.00.175.00 has an older Crystal SP deployed with it (SP 16 I think) - so knowing the Jiwa version being targeted is useful to know when asking about what versions of Crystal are deployed.

Its the latest and greatest, no point in doing development against and older versions if it's possible to avoid it so we try and get people to upgrade as part of the process.

Basically to solve this involves removing everything including Jiwa and then making sure the versions of everything match i.e. you need the correct version of Crystal for visual studio to go with the runtime that Jiwa is using.

It would be handy therefore if the release notes for a version of Jiwa mentioned what the Crystal runtime is if they already don't.

I guess it isn't in an obvious place, but we do mention that in this docs article.

Obvious no, helpful yes, I have to say it's clearer than what the software vendor for Crystal Reports provides.
