Problem with SAP Java Connector (JCo) in Eclipse

Hi all!

I use Eclipse (with ADT) for ABAP development. However, I’ve been having problems with Eclipse since last week. After starting, Eclipse shows an error related to SAP Java Connector (sapjco).

I’ve done some tests with “sapjco 3.1.7” using the jar file. The results are shown below:

JRE 64 bits

sapjco.dll (32 bits): "\eclipse_2022_09\configuration\org.eclipse.osgi\274\0.cp\lib\sapjco3.dll: Can’t load IA 32-bit .dll on a AMD 64-bit platform"
sapjco.dll (64 bits): "\eclipse_2022_09\configuration\org.eclipse.osgi\274\0.cp\lib\sapjco3.dll: %1 is not a valid Win32 application"

JRE 32 bits

sapjco.dll (32 bits): it worked
sapjco.dll (64 bits): "\eclipse_2022_09\configuration\org.eclipse.osgi\274\0.cp\lib\sapjco3.dll: %1 is not a valid Win32 application"

The only way is to use a JRE 32 bits but Eclipse requires JRE 64 bits. What can I do in this case?

Thanks in advance.
